Description:SYSTEM FOR CUSTOMIZING AN IDLE START STOP FUNCTIONALITY AND METHOD THEREOF
TECHNICAL FIELD
[0001] The present subject matter generally relates to system and method for 5 customizing an idle start stop functionality. More particularly, but not exclusively to a system and method of customizing an idle start stop functionality of vehicles based on inputs taken from a user of the vehicle.
BACKGROUND 10
[0002] To make driving a vehicle an enjoyable experience for a user, modern vehicles are provided with supplementary features which will make driving comfortable for the users. During long drives, maintaining constant speed, lane discipline, and constant focus on the road can take a mental strain on the driver. Specifically, for two wheeled vehicles, these are extremely pertinent, 15 as there is an absence of protection from the natural elements such as rain, dust, and wind. Generally, vehicle fuel economy is a very important aspect to be considered, while buying a vehicle by a user. Most importantly, fuel economy becomes more crucial parameter for those users whose livelihood depends on the vehicle wherein the vehicle is used for commercial 20 transportation. Further, the increasing cost of fossil fuels has created an urgent need to look for ways to economize the fuel used in the vehicles. There are many mechanisms available to switch off the vehicle, when not in use or when the vehicle is in idling condition to save fuels.
[0003] One such supplementary feature is an idle start stop feature, which 25 automatically turns-off an engine in a state of vehicle idling. Present day automobiles are equipped with idle stop start (ISS) feature that automatically turn-off an engine in a state of vehicle idling. Specifically, in IC engines, combustion of fuel does not take place steadily and varies at intervals of time based on the automobile throttle state. An idling state occurs when such an 30 engine is kept running when the vehicle is not in use or in a standstill position while parking. Vehicle idling results in unnecessary consumption of fuel by

the engine and emission of harmful gases into the environment. To overcome this, a system to effectively control the engine during idling is placed in such automobiles. Reducing the amount of energy wasted in idling conditions especially at heavy traffic zones significantly helps in gaining better fuel economy for vehicles. 5
[0004] The current idle start stop system comprises of an idle start stop controller. The idle start stop controller engages the integrated starter generator machine upon receiving inputs of a vehicle start method that indicates the intention of the user to start driving the vehicle again.
[0005] Currently, a plurality of parameters are involved in the functioning of 10 the idle start stop system of a vehicle. The plurality of parameters include a timer. For example, if a user is operating the vehicle, and is in an idle condition for a certain time period indicated by the timer set by default, the idle start stop feature will turn-off the engine. However, in conventional idle start stop systems, the timer may not be suitable for certain traffic conditions. 15 For instance, in a heavy traffic situation, a shorter timer duration may be inconvenient for the user, as the engine may get turned off just before the user intends to move the vehicle. In other cases, during long idling period, a longer timer duration may lead to decreased fuel efficiency. Thus, the default settings of the plurality of parameters might not always cater to an individual's 20 specific needs or riding patterns.
[0006] Furthermore, the user may restart the engine by a vehicle start method, achieving safe restart of the engine and avoiding sudden actuation of the vehicle, therefore, avoiding head-on collisions. Conventionally, the vehicle start method includes the application of brakes and throttle simultaneously to 25 restart the engine. In some cases, the vehicle may be restarted by only the application of throttle. Similarly, during heavy traffic, a quicker vehicle start method with less complexity and simultaneous actuating of multiple buttons and switches would be beneficial to the user of the vehicle. Thus, there is a need to enable a user to customize the vehicle start method tailored to their 30 requirements.

[0007] The user being enabled to customize the timer for which the idle start stop system will actuate allows the user to modify the system to wait for longer durations or even allow the user to temporarily disable the system, which will further help to address the safety concerns and provide the users with greater control over the vehicle behaviour and functioning. 5
[0008] Moreover, the default timer settings that are hardcoded into the idle start stop system may lead to excessive engine restarts, which can put strain on the battery and electrical system. There is a need to allow users to set longer timer durations to avoid frequent engine restarts, thereby preserving the life and reducing wear and tear on the vehicle system. 10
[0009] Furthermore, default timer settings might not align with a preference of the user or the traffic conditions that the user is facing. By extending the timer there will be a reduction of unintended engine shutdowns.
[00010] On the other hand, if the timer is set for a long period, it can put excessive strain on a battery of the vehicle, especially in situations where the 15 electrical loads may remain active during the engine shutdown period. Customization of the timer will help the user optimize the duration of the waiting period to strike a balance between fuel efficiency and battery preservation.
[00011] Furthermore, the idle start stop system will be beneficial especially 20 if the vehicle is functioning in certain conditions. For example, if an engine of the vehicle is overheating, the vehicle being switched to idle start stop mode would reduce the strain on the engine of the vehicle, as well as the user will have an uninterrupted riding experience. Similarly, if the vehicle has already travelled a certain distance and the vehicle is low on fuel, the idle start 25 stop mode would help with fuel efficiency and vehicle performance. Therefore, there is a need for a vehicle to automatically switch to an idle start stop mode when certain conditions are satisfied.
[00012] More importantly, the customization of the ideal start stop system will enable the user to alter and modify the plurality of parameters as per the 30 user’s unique requirements and preferences regarding the vehicle functioning.

The inability of a user to calibrate and customize the plurality of parameters that account for an efficient functioning of an idle start stop system contributes to an uncomfortable riding experience. Furthermore, this inability to customize the plurality of parameters takes away the user’s control over their vehicle and are unable to tailor its performance to suit their specific 5 needs and riding style.
[00013] Therefore, there is a need in the art to enable the user to customize and tailor these plurality of parameters easily without the need for complex methods and arrangements. The user must be able to change the plurality of parameters as per their requirements whenever possible without hesitation. 10 Thus, there is a need in the art for a method and a system for an idle start stop system of a vehicle which addresses at least the aforementioned problems and other problems of known art.
[00014] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through 15 comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

[00027] Another objective of the present invention is to enable the user to customize the ISS start method tailored to their requirements. When the vehicle is in the idle start stop mode (ISS mode) and the vehicle is idling, the vehicle can enter into ISS stop and ISS start. ISS stop is based on the parameters as customized by the user. For example, the user can identify 5 plurality of parameters based on which the vehicle will cut the engine off when the vehicle is idling, and the user can customize the plurality of parameters based on their preference. In one embodiment, the ISS stop is triggered based on a timer, which can be customized based on the density of traffic that the user is experiencing. Similarly, an engine temperature crossing 10 a certain threshold when the vehicle is idling can be customized by the user.
[00028] Additionally, the user is able to modify the ISS start method which may include the application of brakes and throttle simultaneously or a quicker ISS start method with less complexity and eliminating the simultaneous actuating of multiple buttons and switches, which would be beneficial to the 15 user of the vehicle.

In an embodiment, the user is enabled to select the timer in the range of 3 seconds to 10 seconds. Therefore, in this embodiment, the user is enabled to customize the time period for which the vehicle should be idling after which the engine will be 10 turned off. For example, if the user selects 3 seconds and the vehicle is in an idle start stop mode, the engine will be turned off after the vehicle has idled for 3 seconds. Similarly, the user can also customize the engine temperature at which the vehicle should turn off the engine when the vehicle is idling. If the engine temperature crosses the engine temperature as indicated by the 15 third set of parameters when the vehicle is idling, the engine is cut off.

[00053] Figure 1 exemplarily illustrates a block diagram of customization of an idle start stop system in accordance with an embodiment of the present disclosure. The control unit (202) is configured to be communicatively connected with the external device (201) wirelessly. This connection between the external device (201) and control unit (202) may be via a Bluetooth 5 connection to enable a swift and quick connection without any hassle. In an embodiment, the external device (201) will be automatically connected to the control unit (202). The control unit (202) is communicably connected to the integrated starter generator controller (203). In an embodiment, the integrated starter generator controller (203) is configured to communicate with the 10 control unit (202) via CAN communication. The integrated starter generator controller (203) is configured to communicate with the integrated starter generator machine (205) via 3-phase communication and the integrated starter generator machine (205) is mechanically coupled with an engine (206) of the vehicle. The integrated starter generator controller (203) is 15 communicatively connected to the Engine Control Unit (204) to ensure that the vehicle is functioning in an efficient manner. In an embodiment, the integrated starter generator controller (203) is communicatively connected to the Engine Management System (not shown). The control unit (202) is connected to a display unit (207) which displays the calibration status and the 20 plurality of calibration parameters that are selected by the user for easier modification.

[00056] Once the connection is established, at step 106, a selection of the plurality of calibration parameters by an external device is made by a user on the external device (201). The external device (201) can be a mobile phone with a mobile application, where the user can choose and select the plurality of calibration parameters on the user interface of the external device (201). 5 The user interface of the external device may have various options to select the plurality of calibration parameters, enabling the user to modify the plurality of calibration parameters easily and swiftly as per their needs. In an embodiment for example, the user may be able to modify the timer being in the range of 3 seconds to 10 seconds, which will determine the time period of 10 vehicle idling after which the engine will be turned off. Furthermore, the user may be able to modify the set of pre-defined conditions, thereby modifying the distance covered by the vehicle in the range of 100 meters to 300 meters and the engine temperature in the range of 40 degree Celsius to 80 degree Celsius. Furthermore, the user may be able to modify the vehicle start method 15 to turn on the engine of the vehicle by customizing the second set of parameters comprising a clutch input, a brake input, a throttle input, and the like, and a time associated with a press of each of the input and a combination thereof.
[00057] Once the plurality of calibration parameters are selected by a user, 20 the calibration parameters are sent to the control unit (202) (shown in Figure 2). At step 108, the control unit (202) calibrates the integrated starter generator controller (203) to operate the vehicle in the idle start stop mode based on the plurality of calibration parameters.
[00058] At step 109, the triggering ON/OFF of ISS mode of the vehicle, by 25 the integrated starter generator controller, based on the first set of parameters is done.

When the vehicle has travelled the distance as indicated by the first set of parameters, or the engine of the vehicle has crossed the engine temperature indicated by the first 30 set of parameters, or input signal is received from the ISS switch the vehicle will switch to ISS mode. In an embodiment, the user is enabled to select the

distance covered by the vehicle being in the range of 100 meters to 300 meters. For example, if the user selects 100 meters to be the distance travelled by the vehicle, the vehicle will trigger the ISS mode when the vehicle has travelled 100 meters. Therefore, if the vehicle has travelled a distance as selected by the user, the vehicle will automatically switch to the ISS mode. 5 This feature enables timely switching to the ISS mode of the vehicle without user interference.
[00059] In another embodiment, the ISS mode is triggered based on the temperature of the engine. For example, if the user has customized the engine temperature parameter to be 60 degrees Celsius, the condition to switch the 10 vehicle to ISS mode is satisfied when the engine temperature has reached 60 degrees Celsius. Therefore, if the engine temperature has reached the setting as selected by the user, the vehicle will automatically switch to the idle start stop mode. This feature enables timely switching to the idle start stop mode of the vehicle without user interference. In an embodiment, the user is enabled 15 to select the engine temperature being in the range of 40 degree Celsius to 80 degree Celsius.
[00060] At step 110, the vehicle will be operated in the idle start stop mode based on the plurality of calibration parameters by the integrated starter generator controller (203). The idle start stop system will be operated 20 according to the modified plurality of calibration parameters. The entering ISS start, by the integrated starter generator controller based on the second set of parameters is done. In an embodiment, the method to enter into ISS start is configured to operate an integrated starter generator machine upon actuation of the second set of parameters. The ISS start is essentially the process to start 25 the engine once it is turned off due to vehicle idling by the idle start stop functionality. Conventionally, the vehicle start method is a simultaneous application of brakes as well as the throttle to indicate the intention to start the vehicle. The present invention provides the user the ability to select and customize the ISS start. The second set of parameters could be a clutch input, 30 a brake input, a throttle input, and a time associated with a press of each of

the input and a combination thereof. Therefore, the vehicle will restart the engine once these inputs are provided by the user to the vehicle.
[00061] At step 111, the entering of ISS stop, by the integrated starter generator controller (203), based on the third set of parameters is done. In an embodiment, the third set of parameters comprises at least a timer, and the 5 engine temperature. As per an aspect of the present subject matter, the integrated starter generator controller (203) is configured to operate an integrated starter generator machine (205) based on the timer. Further, the integrated starter generator machine (205) is configured to operate the engine (206) of the vehicle. In an embodiment, when the vehicle has switched to the 10 ISS mode, the integrated starter generator controller (203) operates the integrated starter generator machine (205), which in turn operates the engine (206) of the vehicle to turn off when the vehicle is idling for more than the time period indicated by the timer. In an embodiment, the user is enabled to select the timer in the range of 3 seconds to 10 seconds. Therefore, in this 15 embodiment, the user is enabled to customize the time period for which the vehicle should be idling after which the engine will be turned off. For example, if the user selects 3 seconds and the vehicle is in an idle start stop mode, the engine will be turned off after the vehicle has idled for 3 seconds. Similarly, the user can also customize the engine temperature at which the 20 vehicle should turn off the engine when the vehicle is idling. If the engine temperature crosses the engine temperature as indicated by the third set of parameters when the vehicle is idling, the engine is cut off.
[00062] At step 112, a display unit will display the plurality of calibration parameters selected by the user as well as the calibration status of whether the 25 idle start stop system has been modified as per requirements successfully.
