FIELD OF INVENTION
The present invention generally relates to a navigation method for a vehicle. More particularly, the present invention relates to a method and system for determining the road status by a vehicle and transmitting the road status to other vehicles.
BACKGROUND OF THE INVENTION
The following description of related art is intended to provide background information pertaining to the field of the present disclosure. This section may include certain aspects of the art that may be related to various aspects of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and therefore, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section.
There are several land transportation modes in the world such as trains, roads etc. Of these, roads are the most commonly used mode. Condition of roads varies from one place to another. A road surface can have bad conditions, such as cracks, bumps, undulations, potholes, or a slippery condition. These bad road conditions can cause vehicular accidents and can cause damage to both vehicle and driver. Further, bad road conditions can also result in inordinate delays.
Existing navigation systems for providing information related to road/terrain conditions comprises front mounted cameras. The cameras captures images of the road/terrain and sends the images to an electronic control unit (ECU)/ vehicle control unit of a vehicle, wherein the captured images are electronically analyzed for detecting possible cracks, bumps, undulations and potholes. Further, the detectable road conditions at a given location on a road/terrain is sent to a central server for informing other users/riders following the same

route. However, the data captured by the camera consists of pixilated information and are not optimum to accurately gauge the cracks, bumps, undulations and potholes present at a given road/terrain.
The other technological advance in the domain started with the use of conventional sensors for collecting road/terrain information and identifying possible cracks, bumps, undulations and potholes in the road/terrain. The sensors such as global positioning unit (GPS), accelerometer, and shock sensor are configured at an electronic control unit (ECU) for detecting in data obtained from shock sensor when vehicle speed decreases due to possible cracks, bumps, undulations and potholes during the ride at the road/terrain. However, the cumulative data used from acceleration sensor and shock sensors in combination with the GPS sensors do not provide a decent resultant data to detect the bad road/terrain information.
Existing road/terrain condition detection systems are capable of detecting abnormalities in the road/terrain without determining the severity of bad conditions. The road/terrain abnormality varies from extremely severe road/terrain conditions to not so severe road/terrain conditions. The determination of severity of negative road condition is helpful to a rider/user in determining an optimum path/route.
Further, existing navigation systems are capable of providing road/terrain information to a plurality of vehicles. However, such systems do not send any alerts or notifications to a user regarding a road/terrain with bad conditions.
Hence, in light of the drawbacks which are aforementioned and inherent in the existing art, there exists a need to provide a system and method for accurately detecting road/terrain abnormalities and transmitting the same to a plurality of vehicles. Further, there exists a need to propose a method and system which determines the severity of road conditions ranging from extremely severe

road/terrain conditions such as large cracks, potholes, dead ends to a minute road/terrain conditions such as small cracks, undulation, slippery road/terrain or traffic condition. In addition, there is a requirement in the art to provide an alert/ notification to user/rider by detecting other user’s movement for avoiding a path with bad road/terrain conditions.

EXAMPLES
The disclosure will now be illustrated with examples, which is intended to illustrate the working of disclosure and not intended to take restrictively to imply any limitations on the scope of the present disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure belongs
Example 1
FIG.1 illustrates an exemplary embodiment of the present invention which encompasses a method [100] of determining at least one road status by a vehicle.
The method [100] initiates at step [102]. At step [104] a user starts driving a vehicle in a particular route/path. At step [106] the at least one vehicle parameter is measured by at least one sensor mounted on the vehicle. The at least one vehicle parameter is selected from the group comprising, but not limited to driving speed, acceleration, deceleration, lean angle, geo location, shock impulse, steering angle, braking occurrence, wheel slip, and combinations thereof.
The at least one vehicle parameter is measured using at least one sensor [503]. The at least one sensor [503] is mounted in the vehicle [502]. The at least one sensor [503] comprises at least one inertial sensor, at least one geo-spatial sensor, at least one gyro sensor, at least one acceleration sensor, at least one

cellular tracking, at least one steering angle sensor, at least one speedometer, at least one traction sensor, at least one temperature sensor, at least one rain sensor, at least one daylight sensor and a combination thereof. Alternatively, the at least one sensor [503] comprises an accelerometer [503a], which is used for obtaining different axial movement, including horizontal movement and the vertical movement of the vehicle due to cracks/bumps/potholes/undulations at the road/ terrain. The accelerometer [503a] is mounted at one of a wheel portion, a suspension system, an axle portion of the vehicle, and combination thereof. The at least one sensor [503] further comprises a gyro sensor [503b] configured in a vehicle for measuring the lean angle and turn angle of the vehicle in all possible directions. Alternatively, the lean angle and turn angle may also be detected by turning of handle or steering of a vehicle. In a scenario when a user detects a potential bad terrain/obstacle/pothole/hurdle/undulation, the user sways from one side of the road/lane to another to avoid the potential bad terrain/obstacle/pothole/hurdle/undulation. Based on the act of the user, the gyroscope and accelerometer detects and records the change and sends the same to the processor for generating at least one road status and/or the at least one alert.
The at least one sensor [503] further comprises a geo-location sensor or a global positioning system (GPS) sensor [503c] for determining the location of the vehicle [502]. Thus, at least one vehicle parameter is measured using one or more sensors [503a, 503b, 503c] with the location of the vehicle [502] at an instance when the at least one vehicle parameter is measured. A slippery condition of the road may be detected by measuring the wheel slip of the vehicle. The wheel slip may be measured by comparing the motor torque with the wheel torque. At step [108] the at least one vehicle parameter is transmitted to a processor [504]. Alternatively, a combination of two or more vehicle parameters is sent to the processor [504].

At step [110], comparison of the at least one vehicle parameter takes place, wherein the processor [504] compares the at least one vehicle parameter with at least one upper threshold value and at least one lower threshold value for generating at least one road status or at least one alert. Alternatively, a combination of two or more vehicle parameters are compared with two or more upper threshold value and lower threshold value for generating the at least one road status and/or the at least one alert. The at least one upper threshold value and the at least one lower threshold value are pre-defined values for determining the severity of cracks/bumps/potholes/undulations/slippery conditions of the road. The at least one road status comprises at least one alert and/or at least one road condition. The at least one road condition is generated if the at least one vehicle parameter is greater than the at least one lower threshold value. The at least one road condition and the at least one alert is generated if the at least one vehicle parameter is greater than the at least one upper threshold value. The at least one road condition comprises data related to the condition of the road including but not limited to detection of cracks/ potholes/ bumps/ undulations/ slippery condition/ traffic congestion/ dead ends or combination thereof. The at least one alert may comprise but not limited to audio alert, video alert, luminous alert, haptic feedback, and superimpose on the real time map. The at least one alert is generated when the condition of the road is extremely severe and that can be detected when the at least one vehicle parameter is found to be greater than the upper threshold value.
At step [112] the processor [504] sends the at least one road condition and/or the at least one alert to a central server [505]. The process ends at [116].

The at least one upper threshold value and the at least one lower threshold value may be static or dynamic. The static value of the at least one upper threshold and the at least one lower threshold may have a fixed value and may be pre-configured in the processor [504] by the central server [505]. The dynamic values of the at least one upper threshold and the at least one lower threshold may keep changing and may be updated in the processor [504] by the central server [505], wherein the updating may take place in real-time or in a pre-determined time intervals. The at least one alert and the at least one road condition may also be static or dynamic. The static value of the at least alert and the at least one road condition may have a fixed value and may be pre-configured in the processor [504] by the central server [505]. The dynamic value of at least one alert or the at least one road condition may keep changing and may be updated in the processor [504] by the central server [505], wherein the updating may take place in real-time. Alternatively, the updating of the dynamic at least one alert and the at least one road condition may be done in pre¬determined time interval. The value of the at least one upper threshold value, the at least one lower threshold value, the at least one alert and/or the at least one road condition is dependent on the type of the vehicle. A two wheeled vehicle may have a different threshold values than the threshold value for a car or a truck and may receive different alert type than the alert for the car or a truck.
Example 2
The present invention encompasses an alternate process [200] of determining at least one road status by a vehicle [502] and as illustrated in FIG. 2. The method [200] initiates at step [202]. At step [204] user starts driving a vehicle in a particular route/path. The at least one vehicle parameters starts varying with the road surface. At step [206] the at least one vehicle parameter is measured using at least one sensor [503]. At step [208] the at least one vehicle parameter is

transmitting to the central server [505], wherein the at least one vehicle parameter is compared with the at least one upper threshold value and the at least one lower threshold value at step [210]. Further at step [212], the at least one road condition and/or the at least one alert is generated by the central server [505] based on the comparison of the at least one vehicle parameter with the at least one upper threshold value and the at least one lower threshold value. The process ends at step [216].
The at least one upper threshold value and the at least one lower threshold value may be static or dynamic. The static value of the at least one upper threshold and the at least one lower threshold may have a fixed value and may be pre-configured in the processor [504] by the central server [505]. The dynamic values of the at least one upper threshold and the at least one lower threshold may keep changing and may be updated in the processor [504] by the central server [505], wherein the updating may take place in real-time or in a pre-determined time interval. The at least one alert and the at least one road condition may be dynamic. The static value of the at least alert and the at least one road condition may have a fixed value and may be pre-configured in the processor [504] by the central server [505].
The dynamic at least one alert or the at least one road condition may keep changing and may be updated in the processor [504] by the central server [505], wherein the updating may take place in real-time. The dynamic updating of the at least one alert or the at least one road condition may be done in at pre¬determined time intervals or in real time. The value of the at least one upper threshold value, the at least one lower threshold value, the at least one alert and/or the at least one road condition is dependent on the type of the vehicle.

Example 3
FIG.3 illustrates an exemplary embodiment of the present invention which encompasses a method [300] of inter vehicle remote communication of at least one road status. The method [300] initiates at step [302]. At step [304] a central server [505] receives the at least one road status determined by a method [100] or [200] from one or more vehicle. The road status may comprise the at least one alert and/or the at least one road condition or vehicle parameter. At step [306] the central server [505] sends the at least one road condition and/or the at least one alert to other users / vehicles following the same route/path without analysing the at least one road status and/or the at least one alert. In an alternative, the central server [505] analyses the at least one road status and/or the at least one alert before sending it to other users. The user following the same route may change his route or vehicle settings to encounter the bad road condition. The user response may be observed by the processor [504] and sent to the central server [505]. At step [308] the central server [505] receives the at least one road status from the user. At step [310] the server updates the new road status for a particular road. The process [300] terminates at step [312]. Therefore, the central server [505] receives the road status from one vehicle/user and transmits the same to other vehicles / users following the same route. Thus, the road status determined by one vehicle can be transmitted to other vehicles via the central server [505].
Example 4
FIG.4 illustrates an exemplary embodiment of the present invention which encompasses a method [400] of inter vehicle remote communication of at least one road status. The process [400] starts at step [402]. At step [404] the central server receives at least one vehicle parameter of a vehicle. At step [406] the central server [505] compares the at least one vehicle with the at least one upper threshold value and the at least one lower threshold value. At step [408]

the central server [505] generates the at least one alert and/or the at least one road condition based on the comparison of the at least one vehicle parameter. Further, the central server [505] sends the at least one alert or the at least one road condition to the users following the same route. At step [410] the central server [505] receives the new vehicle parameters of the vehicle and updates the new alert and/or the new road condition. The process [400] terminates at step [412].

The disclosed method and system is advantageous over existing navigation methods and systems since the presently disclosed method and system not only determines the road condition but also alerts plurality of users in real time following the same road/route and thus actively assists a user to informatively choose a particular route/road.
In a most exemplary depiction of the present invention, the present invention provides a method and system whereby a vehicle measures various road parameters via sensors and generates actionable information such as generation of road condition or alerts, which can be communicated to other vehicles via a central server. The road condition or alerts are generated by comparing the recorded vehicle parameters to values which are preferably updated in real time by the server, thus providing real time updates to a plurality of users for optimum route determination and route condition update. The information generated (road condition or alert) can be overlaid on road map information such as navigation maps.
However, a person skilled in the art may be cognizant of the fact that types of sensor used for determining various vehicle parameters, types of communication means, display means may vary with respect to the type of the vehicle.

Although the present invention has been described in considerable detail with reference to certain preferred embodiments and examples thereof, other embodiments and equivalents are possible.
