FIELD OF INVENTION
The present disclosure generally relates to the field of automobiles, more specifically the present disclosure relates to adaptive cruise speed control assistant system and a method thereof.
BACKGROUND OF THE INVENTION
Cruise control is a smart well-known feature in existing vehicles which enables maintaining a set speed without using an accelerator unless manually override by a driver through clutch, brake or other manual operation. Once a particular speed is selected, driver can take his/her foot off the accelerator and the vehicle cruises at the selected speed. Recent upgradation in the cruise control is “adaptive” cruise control (ACC) in latest vehicles. The ACC is further advancement of the conventional cruise control in a way that the adaptive cruise control automatically adjusts the speed of the vehicle to match the speed of a preceding vehicle of the vehicle. The ACC automatically matches the speed of the running vehicle automatically if the preceding vehicle slows down. Such a system uses sensors and radar to monitor the distance between the preceding vehicle and the running vehicle. Advanced ACC which is known as advanced driver assistance system (ADAS) involves resetting of cruise speed automatically once the foot is taken off the accelerator and cruise control is activated.
There are many conventional arts which disclose various systems and methods related to adaptive speed cruise control or ACC. In one of the conventional arts, automatic control of speed for a vehicle is based on using speed setting, actual speed, acceleration and the change of the slope of the road to set fuel flow for improved fuel mileage. However, such a system tends to optimize the fuel mileage depending upon one factor only i.e. slope of the road. There are other factors as well which contribute to range and mileage of the vehicle.
Range is distance covered by a vehicle for a given fuel volume or charge for the vehicle. In the conventional arts, range is predicted primarily on the basis of past driving history of the user. Some vehicles use eco mode to get better range.
Mileage is distance covered per unit fuel or electric charge (km/litre or km /Kwhr). Various factors include engine capacity, sitting capacity, load capacity affect mileage of the vehicle. One of the conventional arts introduce mileage predicting and optimization system for a normal vehicle lacking ACC. However, such a system is dependent only on tyre pressure and lack other aforementioned factors which also contribute to range and mileage considerably.
More factors including such as but not limited to speed, number of passengers sitting, goods load, tyre pressure, air conditioning, use of vehicle till date, and so on also affect the range and mileage considerably when the vehicle is in running condition and is on road. Previous driving history of the vehicle is used to predict the range (distance to be covered) with the available fuel in conventional prior arts. If the conditions vary, predicted range is very inaccurate and user runs out of fuel midway. Range and mileage prediction is being done conventionally without taking into account number of passengers, tyre pressure, use life of vehicle, load on vehicle, Air Conditioning status, and so on.
For declaring range, different speed cycles are used and vehicle is tested on a test track with different speeds. User is not informed about range at constant speed i.e. at cruise speed with different passenger load, tyre pressure etc.
Range, speed, mileage, cost/km are dealt independently. Correlation between such parameters is not fully utilised to help the user take informed decisions regarding optimisation of Range, speed, mileage, cost/km, Fuel volume/km.
Coordination between the vehicles to exchange goods/passengers is being done manually in isolation without considering Range, cost/km or fuel refill cost.
Travel time and distance advisories are based on average traffic speed predictions. User is not informed about cruise speed settings to attain higher range, fuel cost/km goals along with meeting “Just IN” and “Just Out Time” in given geographical area.
Alternate routes distance & time information is available to user for same start and end location. Fuel Running Cost and fuel refill cost on alternate routes as per vehicle make and model is not available to user.
For example, A user sets Range goal as 100 km, and Adaptive cruise speed setting is 90 Km/hr. Suppose, fuel tank contains 10 litres of fuel, then mileage is 10 km/litre at speed 90 km/hr while mileage is 12km/litre at speed 80 km/hr. Range is 100 km at speed 90 km/hr and range is 120 km at speed 80 km/litre. Then, the Adaptive cruise speed setting can be modified to 80 Km/hr and Range goal can be modified to 120 km, which is as per speed vs Range characteristics (or graph) of vehicle under standard conditions with a given fuel/charge in vehicle. Thus, there is requirement to command automatic modification of Adaptive cruise speed setting depending upon the ‘Range’ goal. Similarly, modification can be done considering ‘Mileage’ as goal. Range and mileage prediction can also be modified by taking into account number of passengers, tyre pressure, use life of vehicle, load on vehicle, Air Conditioning status, and so on.
In another example, a user sets fuel cost/km goal as INR 9/km, cruise speed setting as INR 90 Km/hr. However, the fuel cost varies in different geographical regions. Thus, there can be requirement to modify the adaptive cruise speed setting depending upon the variable fuel cost/km. Similarly, modification can be done depending upon fuel volume/km i.e. volume of fuel in the fuel tank or amount of charge of battery in electric vehicle or volume of CNG in CNG cylinder of the vehicle. Furthermore, there can be modification in the adaptive cruise speed setting depending upon setting low fuel volume/km to save environment.
There is need to have a system which can adapt to cruise speed as per Travel distance & time restrictions compliance in different geographical areas of user. User wants to set “Travel distance & time restrictions” as a goal. For example, a user has a cruise speed setting of 90 Km/hr. As per local traffic laws, the user must cross forest area of 100 km within 1 hour as exit is not allowed after 1 hour of his entry time. Length of the route is 100 km. User cruise speed setting is 90 Km/hr. However, there is need of a system to modify adaptive cruise speed as 100 km/hr to cross the area. This is as per compliance of local traffic or other laws of the given geographic area. In another example, the adaptive cruise setting requires modification as per closing and opening gate timings of a particular zone. In another example, an aeroplane is moving at cruise speed of 1000 km /hr and landing runway is 800 km away. Runway may be available for landing after 1 hr only. So, there may be requirement to modify the adaptive cruise speed to 800 km/hr to avoid traffic congestion in air space near airport, reduce load on Air Traffic control system, avoid mid-air collision and reduce pollution near airports. Similarly, for trains approaching a railway station, vehicles approaching a charging station for EV charging, vehicles approaching fuel station or gas station, buses approaching a bus stand, ships approaching a sea port, and so on.
There is need of the system to inform, train and assist the user to use the vehicle at optimum speed to reduce fuel cost/km, reduce pollution, to refill/charge vehicle as per the geographical constraints forecast and to achieve other goals through audio/video instructions.
There is a need to adapt to new cruise speed automatically/ manually to reach just in/out time in a charging station to optimise waiting period or optimise charging cost wherever charging cost varies with Time of the Day (TOD) or parking cost is variable or reduce pollution or reduce traffic or reduce number of accidents.
There is need to adapt to new cruise speed automatically/ manually with an objective to coordinate between two or more vehicles and their control room to optimise waiting period or optimise charging cost wherever charging cost varies with Time of the Day (TOD) or parking cost is variable or reduce pollution or reduce traffic or reduce number of accidents.
There is need to adapt to new cruise speed automatically/ manually with an objective to determine fuel costing as per geographic area, for example, the fuel costing varies from one state to another state. In such a scenario, the user may be beneficial as he may decide for example if he should purchase fuel from a particular state or wait to reach to next state basis low fuel price.
The existing systems lack assisting the adaptive cruise speed control systems to modify automatically depending upon one or more goals in terms of Range (in Km), Mileage (Km/litre), Fuel cost /km (INR/litre), Fuel volume /km, Travel distance & time restrictions compliance in different geographical areas.
Therefore, there requires a need for the systems and methods to get rid of the aforementioned systems and methods.

Speed vs mileage table may be drawn by running the vehicle with constant speed and measuring the distance when fuel consumed is one litre. Such a process of measuring is mentioned in Bureau of Indian standard BIS 11921. Other examples of such tests of the above process of measuring may include such as but not limited to other Constant Speed Fuel Consumption Test (CSFC) and similar test available in different countries having different standards. Using speed vs mileage relation, other parameters including such as but not limited to Range, Fuel Cost/distance, Fuel Volume/distance may also be calculated.

1. Mileage Variations with various factors
Mileage (distance covered per unit volume or charge) depends on speed, number of passengers sitting, goods load, tyre pressure, Air Conditioning, use of vehicle till date etc. when vehicle is in running condition. Various factors used to quantify including such as but not limited to passenger load, Tyre pressure, Air conditioning, Use of vehicle, goods load with respect to given vehicle.
Various Factors to be used in description are defined herein below. Such factor tables numerical values are given as exemplary only to be contemplated for the skilled persons in the art to understand the present disclosure. True value of such factors may be provided by vehicle manufacturer or testing bodies like ARAI or user may experiment and make these tables as per experience.
1.1. Passenger Factor (PF) = Effective Mileage with certain passengers/ Actual Mileage with driver only
Passenger Factor (PF) Table 1A:
Passengers Driver only Driver+1 Driver+2 Driver+3 Driver+4
PF 1.0 0.95 0.90 0.85 0.80
Number of passengers in a vehicle may be determined from a number of following exemplary methods including such as but not limited to:
a) No. of seat belts in “ON” state
Example: In 7-seater vehicle, if 3 seat belts are “ON” means 3 persons are sitting in the vehicle. 4 seats are in “OFF” state means that there are no persons sitting in the remaining 4 seats.]
b) Load cells under seats may detect whether a person is in seat or it is vacant.
c) Axle load may be used to check vehicle load status
d) Manual counting by driver/user
As number of passengers increase, fuel efficiency i.e. mileage (km/litre) decreases as given in Table 1A above.
1.2. Tyre pressure factor (TPF) = Effective Mileage with certain tyre pressure/ Actual Mileage with recommended tyre pressure.
Tyre Pressure Factor (TPF) in below Table 1B:
Tyre pressure as % age of recommended tyre pressure value 100 % 90 % 80 % 70 % 60 % 50 %
Tyre Pressure Factor TPF 1.00 0.98 0.96 0.94 0.92 0.90
Tyre pressure is available on vehicle CAN (Connected Area Network) through tyre pressure monitoring system (TPMS) or can be fed manually by the user.
As tyre pressure decreases, TPF decreases. Tyre Pressure data is taken from TPMS (114) and fed to microcomputer (152) for calculating the TPF or user feeds it manually.
1.3. Use Factor (UF)= Effective Mileage with used or old vehicle/ Actual Mileage with new vehicle.
Use Factor (UF) table as shown in below Table 1C
Odometer reading (Km) 0 50000 100000 150000 200000 250000
Use Factor UF 1.00 0.96 0.92 0.88 0.84 0.80
As distance covered by the vehicle increases with use, UF decreases. Use of vehicle data is taken from odometer (112) and fed to microcomputer (152) for calculating Use Factor (UF). OR user feeds it manually.
1.4. Air Conditioning Factor (ACF) =Effective Mileage with certain air conditioner setting/ Actual Mileage with zero or no air conditioning.
Air Conditioning Factor (ACF) Table in Table 1D
Air conditioning levels (%age of max) AC OFF Level1 (20 %) Level2
(40 %) Level3
(60 %) Level4
(80 %) Level5
(100 %)
AC Factor (ACF) 1.0 0.98 0.97 0.96 0.95 0.94
As air conditioning level in vehicle increases, the ACF decreases. Air conditioning data is taken from the Air conditioning status monitor (118) or CAN or current supply of an Air conditioner is used and fed to microcomputer (152) for calculating the ACF or the user feeds thereto manually.
1.5 Load factor (LF) = Effective Mileage with certain tyre pressure/ Actual Mileage with recommended tyre pressure.
Load Factor (LF) Table as shown below in Table 1E
Load %age 0 % 25 % 50 % 75 % 100 %
Load Factor LF 1.0 0.9 0.8 0.7 0.6
Load is sensed through load sensors in vehicle and Load data is available on vehicle CAN (Connected Area Network) or can be fed manually by the user.
As load increases, LF decreases. Load data is taken from load sensors and fed to microcomputer (152) for calculating LF or the user feeds thereto manually.
1.6 Net factor (NF) = PF x TPF x UF x ACF x LF
Net Factor (NF) is product of all the factors as disclosed aforementioned. After all the above factors are available, the microcomputer (152) calculates NF by multiplying all the five factors discussed above and is explained below through an example.
Example 1: NF = PF x TPF x UF x ACF x LF = 1 x 1 x 1 x 1 x 1 = 1 under ideal cases
Example 2: NF = PF x TPF x UF x ACF x LF = 0.9 x 0.98 x 0.96 x 0.96 x 0.9 = 0.73 when different factors have different values.
2. Range Goal
User has certain value of fuel or charge and wants to cover certain distance without running out of fuel. Range depends on the speed of vehicle. User may change range by controlling the speed of the vehicle. User may attain desired range by getting adaptive cruise speed setting automatically or manually adjusting the cruise speed.
Following steps are followed while accounting for range variation with speed only. Effect of other factors including such as but not limited to number of passengers sitting, goods load, tyre pressure, Air Conditioning, use of vehicle till date etc. accounted subsequently.
As shown in Figure 3 (discussed hereinafter), distance between starting point 1 and end point 2 is (say) 60 km. Distance to be covered for up and down journey is 120 km.
The system (100) may set new adaptive cruise speed such that vehicle completes journey without running out of fuel/charge.
Step 1: User enters start and end points in a given geographical area (Figure 3) through the input device (102 ) and connected to GPS cloud server (126) for maps and navigation. Starting point is 1 and end point is 2 in figure 3 of geographical area.
Step 2: The system (100) checks fuel available in fuel tank through fuel volume sensor and charge available in battery (106) for the electric vehicle. As an example, available volume is 10 litres in fuel tank (104).
Step 3: The system (100) checks availability of fuel/charging stations in routes 1 to 2 and 2 to 1. Such a step is done by map solution API. The system (100) checks if the fuel station is functional and has the capacity to supply fuel or charge the vehicle. Such a data is available through various platforms known in the art, including such as but not limited to Map Solution and available on the GPS cloud server (126).
Step 4: The system (100) checks maximum distance (range) which may be covered at cruise speed set by user or car manufacturer or fleet owner (say 90 km/hr) and corresponding mileage (say 10 km/litre) as per speed v/s mileage data (fix for a given vehicle as per B.I.S standards).
Speed v/s mileage data is available in the memory of the microcomputer (152) or available on the GPS cloud server (126) and is given hereinabove as Table 1 as an example.
Other parameters including such as but not limited to Range, cost/km and Fuel consumed/distance is also given as a function of speed.
The system (100) calculates the range, (at speed 90 km/hr, mileage is 10 km/litre).
Here the range is = 10 km/litre x 10 litre = 100 km
Step 5: The system (100) checks the total distance to be covered from 1 to 2 and back to point 1(say 120 km) through distance map API.
Step 6: If the value in step 5 > value in step 4, then the system (100) resets the cruise speed such that the new range (maximum possible distance) is enough to complete the journey.
Here, the system (100) sets another cruise speed (say 80 km/hr) for which the mileage (12 km/litre) as per speed v/s mileage in Table 1. As per the Table 1, range is 120 km at speed 80 km/hr.
So, new cruise speed reset = 80 km/hr
Hence, the system (100) is able to perform following functions:
a) Auto reset new cruise speed (say 80 km/hr) by giving a command to the cruise speed control setup (104) and informs the user about the new cruise speed. The user may manually override the new cruise speed (80 km/hr) and manually keep it to any value. (say 90km/hr or 70 km/hr or any other value).
b) Auto suggest new cruise speed (say 80 km/hr) through audio/ pop-up/ animation on audio/ video output display (132). The user may set or ignore it.
c) Give reasons for auto reset of cruise speed (say 80 km/hr) through audio/video display (132) or through the Personal Digital Assistant (122).
Example: “Dear user, you may run out of fuel/ charge if you cruise at 90 km/hr. System is setting a new cruise speed (say 80 km/hr) to increase the mileage (from 10 km/litre to 12 km/litre) and increase the range from (100 km to 120 km) so that you can complete the journey without running out of fuel or charge. You can manually set/reset cruise speed at your own risk.”
2.1 Range goal with variation in number of passengers i.e., Passenger Factor (PF)
As number of passengers increases, fuel consumption increases. Mileage and Range decrease.
The vehicle mileage v/s speed along with variation due to number of passengers may be given by vehicle manufacturer or third parties in Automobile research or user may find out by performing experiments on his vehicle as per Bureau of Indian Standard BIS 11921 and varying the number of passengers.

3 Various procedural steps for adaptive cruise speed for Range goal method
As shown in Figure 11A, method steps for achieving Range Goal
Step1: Check Range at cruise speed set by user or manufacturer, if any.
Example: Range = 100 Km at cruise speed = 90 Km/hr.
Step 2: Required Range to complete the journey either from Map API or Manual calculation by user.
Example: Required Range = 120 Km to complete the journey.
Step 3: Either automatic or manual feed of all five factors PF, TPF, UF, ACF, LF
Step 4: Calculate Net factors as, NF = PF x TPF x UF x ACF x LF
Example: NF = 0.9 x 0.98 x 0.96 x 0.96 x 0.9 = 0.73
[If any factor is not fed, it is taken as 1]
Step 5: Find speed as per Table 2F. i.e., speed for which effective range is more than 120 Km with given NF. (here NF =0.73).
Get the corresponding cruise speed from Table 2F.
As per table 2F, Speed = 50 Km/hr.
Step 6: Automatically feed above speed (say 50 km/hr) to adaptive cruise control system or advise Adaptive cruise speed = 50 km/hr to user.
If recommended adaptive cruise speed is not within speed limits permissible by local laws, information/warning is given to user and he can override this warning at his own risk.
Step 7: Display adaptive cruise speed = 50 km/hr.
Either the system (100) feeds thereto automatically or the user does thereto manually.
Step 8: If Range goal is too high and may not be achieved, informs the user
Example: Range goal set by user = 130 km when NF=0.73
Following message appears on the display (132):
“Range goal is not possible with this vehicle. Maximum Range of 124.1 possible at cruise speed of 50 km/hr. Set lower possible Range goal”
Step 9: Adaptive Cruise speed value is transferred to Cruise speed control setup (104) and information is given to the display (132) and PDA (122).
4 Adaptive cruise speed setting to achieve Mileage Goal
The system (100) adapts to cruise speed as per “Mileage goal” of user.
User wants to set Mileage as a goal.
User has certain value of fuel or charge (for Electric Vehicle) and wants to cover certain journey with some Mileage as goal. Mileage depends on the speed of vehicle. User may change mileage by controlling the speed of the vehicle. User may attain desired mileage by getting adaptive cruise speed setting automatically or manually adjust the cruise speed.
Example: A user sets mileage goal as 10 Km/litre, cruise speed setting is 90 Km/hr. Now user modifies and sets mileage goal as 12 km/litre. The system (100) modifies Adaptive cruise speed setting to 80 km/hr. This is as per speed vs mileage characteristics (or graph) of vehicle under standard conditions.

Example: 10 Km/litre at speed 90 Km/hr
Step2: Required Mileage Goal = 12 Km/litre
Step 3: Either automatic or manual feed of all five factors PF, TPF, UF, ACF, LF
Step 4: Calculate Net factor, NF
Example: NF = PF x TPF x UF x ACF x LF = 0.9 x 0.98 x 0.96 x 0.96 x 0.9 = 0.73
[If any factor Is not fed, it is taken as 1]
Step5: Find Mileage as per Table 2F.

If recommended adaptive cruise speed is not within speed limits permissible by local laws, information/warning is given to user and he can override this warning at his own risk
Step 7: Display adaptive cruise speed = 50 km/hr.
Either the system (100) sets it automatically or user does it manually.
Step 8: If Mileage goal is too high and cannot be achieved, inform the user
Example: Mileage goal = 14 Km/l when TF=0.73
Following message appears on the display (132):
“(Mileage goal is not possible with this vehicle). Set lower mileage goal”.
Step 9: Adaptive Cruise speed value is transferred to Cruise speed control mechanism (130) and information is given to the display (132) and PDA (122).
6 Fuel cost /km Goal
User has certain value of fuel or charge (for Electric Vehicle) and wants to cover certain journey with some Fuel cost/km as goal. Fuel cost/km depends on the speed of vehicle. User may change Fuel cost/km by controlling the speed of the vehicle. User may attain desired Fuel cost/km by getting adaptive cruise speed setting automatically or manually adjusting the cruise speed.
The system (100) adapts to cruise speed as per “Fuel cost/km goal” of user as and when user wants to set Fuel cost/km as a goal. It is explained through an example below.
Example: A user sets Fuel cost/km goal as INR 9/km, cruise speed setting is 90 Km/hr. Now user modifies and sets Fuel cost/km goal as INR 7.5/km. Need a system to modify Adaptive cruise speed setting to 80 km/hr. This is as per speed vs Fuel cost/km characteristics (or graph) of vehicle under standard conditions with a given fuel price updates as given in Table 1.

Actual Fuel Volume /km under ideal conditions (with NF =1) is 100 ml/km at speed 90 Km/hr.
Required Fuel Volume /km set by user is 85 ml/ Km when Net Factor (NF) =0.73
From the table 5F, effective Fuel Volume /km is less than 85ml/km for speed =50.
Suggested adaptive cruise speed to get above Fuel Volume /km (less than 85 ml/km) is 50 Km/hr.
At 50 Km/hr, effective Fuel Volume /km = 80.54 ml/ Km.
At 50 Km/hr, effective Fuel Volume /km = 80.54 ml/Km which is less than required Fuel Volume /km (85 ml/km) set by the user.
9 Various Procedural steps for Fuel Volume/Km Goal
As shown in Figure 11D, method steps for achieving Fuel Volume/km Goal as follows:
Step1: Check Fuel Volume/Km at cruise speed set by user or manufacturer.
Example: Fuel Volume/Km =100 ml/km at cruise speed = 90 Km/hr.
Step 2: Required Fuel Volume/Km either from Map API or Manual calculation by user.
Example: Required Fuel Volume/Km = 85 ml/km
Step 3: Either automatic or manual feed of all five factors PF, TPF, UF, ACF, LF
Step 4: Calculate Net factor, NF
Example: NF = PF x TPF x UF x ACF x LF = 0.9 x 0.98 x 0.96 x 0.96 x 0.9 = 0.73 (say)
[If any factor Is not fed, it is taken as 1]
Step 5: Find speed as per Table 5F. For Example, Speed = 50 Km/hr.
Table 5F (NF = 0.73)
Speed
(Km/hr) 30 40 50 60 70 80 90 100 110
Fuel Volume
(in ml/Km) 71.4 62.5 58.8 62.5 71.4 83.3 100 111 143
Effective Fuel Volume/Km
(NF = 0.73) 97.80 85.61 80.54 85.61 97.80 114.10 136.98 152.05 195.89
Effective Fuel Volume/Km = 85 ml/km is possible only for speed = 50 km/hr
Step 6: Automatically feed to adaptive cruise control or advise.
Adaptive cruise speed = 50 km/hr
If recommended adaptive cruise speed is not within speed limits permissible by local laws, information/warning is given to user and he can override this warning at his own risk
Step 7: Display adaptive cruise speed = 50 km/hr
The system (100) either sets it automatically or user does it manually.
Step 8: If Fuel volume /km goal is too low and may not be achieved, inform the user.
Example: Volume /km goal = 80 ml/km when TF=0.73
Following message appears on the display (132)
“Fuel Volume/km goal is not possible with this vehicle. Set higher Fuel volume/km goal”.”
Step 9: Adaptive Cruise speed value is transferred to Cruise speed control setup (104) and information is given to the display (132) and the PDA (122)
10 Travel distance & time restrictions compliance goal in different geographical areas.
System can adapt to cruise speed as per Travel distance & time restrictions compliance in different geographical areas of user.
User wants to set “Travel distance & time restrictions” as a goal.
Example: A user has a cruise speed setting of 90 Km/hr. As per local traffic laws, user must cross forest area of 100 km within 1 hour as exit is not allowed after 1 hr of his entry time. Length of the route is 100 km. User cruise speed setting is 90 Km/hr. Need a system to modify adaptive cruise speed as 100 km/hr to cross the area. This is as per compliance of local traffic or other laws of the given geographic area. All local traffic laws and rules are available as data from cloud server in system. It is automatically fed to system. User can feed this data manually for given geographical area.
Example: An aeroplane is moving at cruise speed of 1000 km /hr and landing runway is 800 km away. Runway may be available for landing after 1 hr only. Need a system to modify adaptive cruise speed to 800 km/hr to avoid traffic congestion in air space near airport, reduce load on Air Traffic control system, avoid mid-air collision and reduce pollution near airports.
Similar examples can be given for trains approaching a railway station, cars approaching a charging station for EV charging, buses approaching a bus stand, ships approaching a sea port.
The system (100) is configured to adapt, train and assist the user to use the vehicle at optimum speed to reduce fuel cost/km, reduce pollution, to refill/charge vehicle as per geographical constraints forecast and to achieve other above stated goals through audio/video instructions.
As travel distance & time restrictions are functions of Range, speed, calculation and procedure for this case are same as discussed in previous 4 cases. Application methods are slightly different and will be explained here through different use cases.
Travel distance & time restrictions in geographical area are available as Map API and are conveyed to system through cloud server (126).
11 Multiple Goals
User may set multiple goals. For example, a user may set Range goal of 100 km, Mileage Goal of 10 Km/litre, Cost /km Goal of 9 INR/km and Fuel Volume Goal of 100 millilitre/km for a given Net Factor (NF) of 0.73 (say). All these goals are achieved by suggesting Adaptive Cruise Speed of 70 km/hr. It is as per (Table 2F), (Table 3F), (Table 4F) and (Table 5F). As per these four tables, at Adaptive Cruise speed of 70 Km/hr, Range is 102.2 Km , Mileage is 10.2 km/litre, Cost /km is 8.7 INR/km and Fuel Volume/km is 97.8 millilitre/km which is as per required Range goal of more than 100 km, Mileage Goal of more than 10 km/litre, Cost INR/km Goal of less than 9 INR/km and Fuel Volume Goal of less than 100 millilitre/km for a given Net Factor (NF) of 0.73 (say).
USE CASES
13) Use Case 1: Refer Fig 3
Available fuel= 10 litre
Route length= 60 km up + 60 km down=120 km
Fuel pump at 1 and 2 points are available.
User has crossed point 1 and fuel station at 2 are not working due to any reason. [say timing is over, workers strike, non-availability of fuel due to any reason]
User has set cruise speed= 90 km/hr
Problem: User may not come back to point 1 as vehicle will run out of fuel as up and down distance to be covered= 120 km.
Maximum distance (Range) which can be covered at speed 90 km/hr (mileage 10 km/litre) with a fuel of 10 litre = 10 km/litre x 10 litre = 100 km
So, vehicle may not come back to starting point because vehicle may run out of Fuel or battery is discharged.
Solution: If the set cruise speed is changed from 90 km/hr to 80 km/hr, the new mileage is 12 km/litre as per the standard speed vs mileage graph of the vehicle.
Now if performing calculations again.
Maximum distance which can be covered at speed 90 km/hr (mileage 12 km/litre) with a fuel of 10 litre = 12 km/litre x 10 litre = 120 km
Now, vehicle can come back to starting point without running out of fuel or charge.
Procedure for the Use Case1 is as follows:
Step 1: User to enter start and end location on Map solution application
Step 2: Map API to fetch fuel availability along with fuel prices along the route, up and down journey.
Step 3: MAP API to get total distance (say 120 km) to be covered.
Step 4: The system (100) to measure fuel in tank (or charge in battery) and corresponding Range (say 100 km) at set cruise speed (say 90 km/hr) under standard conditions as per Table 1.
Step 5: System to give audio/ visual warning to user that vehicle may not come back if present cruise speed is maintained. The system (100) give advisory to set a new cruise speed (say 80 km/hr) for which Range is sufficient (say 120 km) so that user can come back without refuelling or recharging. System can automatically set adapted cruise speed (80 km/hr) and inform the user about new adapted cruise speed (80 km/hr)
Step 6: The system (100) to check Net Factor (NF) and do steps 4 and 5 again as per new adapted speed at NF (say 0.73). The system (100) checks all multiple goals set by user discussed in description and set /recommend new adapted speed as per the methods discussed in description earlier.
Step 7: If new adapted speed with NF equal to 0.73 is 50 km/hr, User can manually set new adapted cruise speed (50 km/hr) OR The system (100) set new adapted cruise speed (50 km/hr) OR user can manually override all these warnings/advisories and set any speed of user’s choice at his own risk.
14 Use Case 2: Reference to Figure 4
Available fuel= 10 litre
Route length 1 to P in state A =120 km
In state A, route 1 to P, either fuel pumps are not available OR Fuel price in state A is high in comparison to state B. Fuel pumps are available in path P to 2 in state B.
User may not want to refill between 1 to P due any reason and wants to get refill at or after point P.
User has set cruise speed= 90 km/hr
Problem: User may not reach point P as vehicle may run out of fuel as distance to be covered= 120 km.
Maximum distance (Range) which can be covered at speed 90 km/hr (mileage 10 km/litre) with a fuel of 10 litre = 10 km/litre x 10 litre = 100 km
So, vehicle may not reach point P because vehicle will run out of Fuel or battery is discharged.
Solution: If the set cruise speed is changed from 90 km/hr to 80 km/hr, the new mileage is 12 km/litre as per the standard speed vs mileage graph of the vehicle.
Now if we do the calculations again
Maximum distance which can be covered at speed 80 km/hr (mileage 12 km/litre) with a fuel of 10 litre = 12 km/litre x 10 litre = 120 km
Now, vehicle can cross point P without running out of fuel or charge.
Procedure for this use case1 is as follows
Step 1: User to enter start and end location on Map solution application
Step 2: Map API to fetch fuel availability along with fuel prices along the route in state A and State B along with fuel price and distance of border point P and fuel station distances.
Step 3: MAP API to get distance 1 to P (say 120 km) to be covered.
Step 4: The system (100) to measure fuel in tank (or charge in battery) and corresponding Range (say 100 km) at set cruise speed (say 90 km/hr) under standard conditions as per Table 1.
Step 5: The system (100) to give audio/ visual warning to user that vehicle may not cross point P if present cruise speed is maintained. The system (100) give advisory to set a new cruise speed (say 80 km/hr) for which Range is sufficient (say 120 km) so that user can cross point P without refuelling or recharging. System can automatically set adapted cruise speed (80 km/hr) and inform the user about new adapted cruise speed (80 km/hr) on the display (132).
Step 6: The system (100) to check Net Factor (NF) and do steps 4 and 5 again as per new adapted speed at NF (say 0.73). The system (100) checks all multiple goals set by user discussed in description and set /recommend new adapted speed as per the methods discussed hereinabove.
Step 7: If new adapted speed with NF equal to 0.73 is 50 km/hr, User may manually set new adapted cruise speed (50 km/hr) OR the system (100) may set new adapted cruise speed (50 km/hr) OR user can manually override all these warnings/advisories and set any speed of user’s choice at his own risk.

(Here Net Factor =1)
As per previous history stored in vehicle memory storage or permissible speed is 90 km/hr or User Cruise control speed is 90 km/hr or average mileage as per history of user or approximate mileage given by manufacturer at speed 90 km/hr is 10 km/litre.
By any of above or some other mentioned vehicle declared/calculated/measured mileage is 10 km/litre (say).
If various factors (PF, TPF, UF, ACF, LF) are fed by user, mileage calculation is as per NF as discussed in earlier description.
Total Fuel requirement to complete journey = 360 km/ (10km/litre) = 36 litre
Fuel prices in three states (Geographical area) enroute
State Fuel Price (Rs/litre)
A 88
B 90
C 95
The system (100) performs following steps for use case 3 :
Step 1: Measure fuel in fuel tank by known methods and inform to CPU/ microcontroller.
Step 2: Microcontroller (152) puts in “Fuel tank capacity” from vehicle specification data memory chip/storage.
Say fuel tank capacity= 60 litre
Step 3: CPU will find max possible refill volume at this stage = Fuel Tank capacity – Fuel Available = 60 litre – 10 litre = 50 litres
Step 4: Get route length (say 360 km) from GPS or Map solutions APIs (ONLINE or OFFLINE) as user feeds in starting and end points. Also get route lengths in each state A, B and C.
Step 5: Find names and fuel prices of states (here A, B, C) through which route passes and get data from cloud in following format.

Step 8: Advise the user to get remaining refill capacity of 50 litre to be filled from lowest prices in state A (Punjab) which is user’s starting position.
These advisories may be “text written” or “Audio advisories “or “Animations” or Audio/ Video/Animation/Text pop up on Map display of user audio/video output display used. [Screen, LCD, LED, infotainment, multi-information display, speedometer etc.]
Advisories may be of the following type:
“Dear user, your starting point state A (say Punjab) has lowest fuel price of INR88/ lt. You can save INR7 [INR 95-INR 88] per litre on your trip.”
Or
“Your trip fuel cost will be reduced by INR 350 if you get your fuel tank filled here. Save INR 350. Wish you safe journey.”
Or
“Get your tank filled with 50 litres here and save INR 350[Rs 7/ litre x 50 litres] fuel filled within 20 km as prices will change in next state B (say Haryana).”
Step 9: If user misses refill in State A due to any reason, the system (100) again performs the above process taking “P” as starting point or existing location of user as starting point and point 2 as end point.
Now the advisory may be in the complete form.
“Dear user, your starting state B (say Haryana) is having lower prices in comparison to your end point state C (say Rajasthan).
You can save INR 5/litre [INR 95- INR90].
Get your tank filled with 52 litres here.
[2 litre fuel has been consumed in State A for 20 km route length 1 to P. The system (100) recalculates available refill capacity (52 litres) and save INR 260 (INR 5/litre x 52 litres)]
Step 10: User can set a prefixed time of (say 1) hr each or prefixed distance (say 10 km) before crossing of border of state where fuel prices of bordering states are different to inform/warn/advise the user for tank refill advisory based on optimum fuel prices of states en route.
Step 11: Auto reset of cruise speed control (say from 90 km/litre to 80 km/litre to over some distance in high fuel price area to low fuel price area. It is done as per various goals set by user discussed hereinabove.

The System (100) performs following steps:
Step 1: Measure fuel in fuel tank by known methods and inform to CPU/ microcontroller.
Step 2: Microcontroller (152) puts in “Fuel tank capacity” from vehicle specification data memory chip/storage. Say fuel tank capacity= 60 litre
Step 3: CPU will find max possible refill volume at this stage. = Fuel Tank capacity – Fuel Available = 60 litre – 2litre = 58 litre
Step 4: Get route length (say 360 km) from GPS or Map solutions APIs (ONLINE or OFFLINE) as user feeds in starting and end points. Also get route lengths in each state A, B, C and D.

Step 6: Identify states where fuel price is lowest, highest and arrange them in increasing order or decreasing order as per fuel prices. Do the same for both routes one and two.
Step 7: Display (122) and temporary store in memory for the system (100), fuel prices on maps display with lowest fuel prices in (say in green) and highest (say in Red) for all states for both routes.
Step 8: Available fuel (2litre) is sufficient to cover only 20 Km at speed of 90 km/hr. (Mileage 10 km/litre at speed 90 km/hr as per Table 1).
The system (100) compares route one and route two lengths in each state along with fuel prices.
The system (100) advises adaptive reduced speed of 80 km/hr to cover 24 km distance (1 to R) and refill in state D (reduced fuel price of 78INR /litre).
It is done as per various goals set by user discussed in description so far.
Advise the user to get remaining refill capacity of 58 litre to be filled from lowest prices in state D.
The system (100) advises to opt for Route two i.e., Refill in state D (not state B).
It will result in saving = INR 12/litre x 58 litre = INR 696.
Fuel Bill saving of INR 696 advisory can be given to user for manual or automatic adaptive speed control with a display.
These advisories can be “text written” or “Audio advisories “or “Animations” or Audio/ Video/Animation/Text pop up on Map display of user audio/video output display used. [ Screen, LCD, LED, infotainment, multi-information display, speedometer etc]
Advisories may be of the following type:
“Dear user, state D has lowest fuel price of INR78/ lt.
You can save INR12 [ INR 90-INR 78] per litre on your trip if you follow Route two through state D”
Or
“Your trip fuel cost will be reduced by INR 696 if you get your fuel tank filled in state D. Wish you safe journey.”
Or
“Get your tank filled with 58 litre in state D and save INR696[INR 12/ litre x 58 litre] fuel filled after covering 24 km on route two, and enter state D as prices in state D are lowest”
Step 9: If user misses refill in State D due to any reason, the system (100) re does the above process.
Step 10: User can set a prefixed time of (say 1) hr each or prefixed distance (say 10 km) before crossing of border of state where fuel prices of bordering states are different to inform/warn/advise the user for tank refill advisory based on optimum fuel prices of states en route.
Step 11: Auto reset of cruise speed control (say from 90 km/litre to 80 km/litre to cover some distance in high fuel price area to low fuel price area on two different routes as per above steps logic. It is done as per various goals set by user discussed in description so far.
17 Use case 5: Figure 6
Vehicle is at point 1 at certain time (say 6 PM).
Entry point P (in state B) has in time after 8 PM and exit point Q has exit time before 9 PM (say).
Distance 1 to P = 160 km and distance P to Q = 100 km.
Vehicle present set cruise speed is 90 km/hr.
Vehicle will reach point P in 1 hr 47 minutes.
Entry at P is allowed only after 2 hrs i.e., by 8 PM only.
Step 1: The system (100) fetches all entry and exit times of all geographic areas en route.
Step 2: The system (100) advises the adaptive cruise speed of 80 km/hr to cover 160 km and reach just in time at P at 8 PM. It will reduce cost/km and reduce pollution as discussed hereinabove.
(It avoids traffic jams /parking fee /waiting charges etc at point P)
Step 3: The system (100) automatically sets Adaptive cruise speed of 80 km/hr to cover 160 km and reach just in time at P at 8 PM. It may be informed to user who can accept or manually override it.
Step 4: The system (100) advises adaptive cruise speed of 100 km/hr so that vehicle exits point Q within one hour i.e., 9 PM.
Step 5: The system (100) automatically sets Adaptive cruise speed of 100 km/hr to cover 100 km (P to Q) and reach just in time at Q at 9 PM. It may be informed to user who can accept or manually override it. It is done as per various goals set by user discussed hereinabove.
18 Use case 6: Reference to Figure 7

As an example, X is a charging station at distance 80 km from point 1.
At present, vehicle is cruising at speed 90 km/hr. Vehicle may reach station X in 8/9 hrs. Charging port may be available after one hour only. Vehicle may have to wait 1/9 hrs.
So, the system (100) may be configured to set/advise adaptive cruise speed of 80 km/hr so that vehicle reaches in 1 hour i.e., Just in time to avoid any waiting/traffic jam etc. at station X.
Another example is, station X is 100 km and vehicle is cruising at 90 km/hr.
Station X will close after one hour.
So, the system (100) may be configured to set/advise adaptive cruise speed of 100 km/hr so that vehicle reaches in 1 hour i.e., Just in time to avoid delay for charging.
Procedural steps to be followed are almost same as use case 5.

Adaptive cruise speed system can help both reach same time if both the vehicles are having the proposed system.
Both vehicles’ users have information (through Map APIs) regarding coordinates of station Y and coordinates, speed, stay time of both vehicles at station Y.
Adaptive cruise system may set/advise vehicle A to adapt to new cruise speed of 100 km/hr and reach station after 1 hr from present position 1.
The system (100) set/advise vehicle B to adapt to new cruise speed of 80 km/hr and reach station after 1 hr from present position 2.
Both vehicles may reach just in time at station Y.
It may help vehicles to reach in time and save fuel, reduce wait time outside station, reduce risk of accidents and reduce passenger/ goods rush on station Y. Here station Y is a junction point having connectivity in two or more directions.
Figure 2 represents integration of the system (100) with existing cruise speed control mechanism (conventionally known). The controller (208) takes input from the microcontroller (152) or the input device (102) to set cruise speed. The controller (208) gives input to the actuator (210) which controls the throttle in combustion engine or current in motor in an electric vehicle. The engine or motor (212) further controls the speed of the wheel (214) or vehicle. Speed feedback (216) is available to the controller (208) to set or adjust the actuator (210) to cruise control speed of the vehicle. System ON/OFF display (202) may be an LED or audio signal to inform the user that system is ON or OFF. Audio/ video output (204) is used to interact with users regarding cruise speed control information. Vehicle CAN (206) is similar to Vehicle CAN as the vehicle may have two or more information channels.
