Method And System For Correcting Velocity Of Autonomous Vehicle To Navigate Along Planned Navigation Path

Abstract: Disclosed subject matter relates to field of telematics that performs a method of correcting velocity of autonomous vehicle to navigate along a planned navigation path. A velocity correcting system may receive a velocity for navigating the autonomous vehicle for a selected segment along the planned navigation path and may identify plurality of values corresponding to current vehicle condition while the autonomous vehicle is navigating along the planned navigation path and may determine a counter angular velocity corresponding to current vehicle condition by comparing the plurality of values with pre-stored values. Finally, velocity is corrected by correlating the velocity with counter angular velocity and provided to navigation module for applying the correction velocity. The present disclosure eliminates need for continuous monitoring and steering angle adjustment to align the autonomous vehicle with planned navigation path, thereby reducing power consumption and minimizing jerks experienced by autonomous vehicle.

Specification

Claims:We claim:
1. A method of correcting velocity of an autonomous vehicle (103) to navigate along a planned navigation path, the method comprising:
receiving, by a velocity correcting system (107) associated with the autonomous vehicle (103), a velocity for navigating the autonomous vehicle (103) for a selected segment among one or more segments along the planned navigation path;
identifying, by the velocity correcting system (107), a plurality of values corresponding to a current vehicle condition, for the selected segment, while the autonomous vehicle (103) is navigating along the planned navigation path;
determining, by the velocity correcting system (107), a counter angular velocity corresponding to the current vehicle condition by comparing the plurality of values with pre-stored values, wherein the pre-stored values are generated based on a trial run of the autonomous vehicle (103) under various predefined conditions of the autonomous vehicle (103); and
correcting, by the velocity correcting system (107), the velocity of the autonomous vehicle (103), by correlating the velocity with the counter angular velocity, and providing the correction velocity to a navigation module (114) associated with the velocity correcting system (107), for applying the correction velocity to navigate the autonomous vehicle (103) along the planned navigation path.

2. The method as claimed in claim 1, wherein the plurality of values corresponding to the current vehicle condition are measured with respect to wear and tear condition of the autonomous vehicle (103), based on one or more parameters comprising at least one of a speed of the autonomous vehicle (103), a load condition of the autonomous vehicle (103), a slope of the planned navigation path and a curvature of the planned navigation path.

3. The method as claimed in claim 1, wherein the pre-stored values corresponding to the various predefined conditions of the autonomous vehicle (103) are associated with a corresponding counter angular velocity.

4. The method as claimed in claim 1, wherein the plurality of values corresponding to the current vehicle condition are identified using one or more sensors configured in the autonomous vehicle (103).
5. The method as claimed in claim 1, wherein the correction velocity is iteratively applied for the selected segment at every predefined cycle time, wherein a number of iterations for the selected segment is determined in real-time.

6. The method as claimed in claim 5, wherein the number of iterations is determined based on a speed of the autonomous vehicle (103) and length of the selected segment.

7. A velocity correcting system (107) for correcting velocity of an autonomous vehicle (103) to navigate along a planned navigation path, the velocity correcting system (107) comprising:
a processor (109); and
a memory (113) communicatively coupled to the processor (109), wherein the memory (113) stores the processor-executable instructions, which, on execution, causes the processor (109) to:
receive a velocity for navigating the autonomous vehicle (103) for a selected segment among one or more segments along the planned navigation path;
identify a plurality of values corresponding to a current vehicle condition, for the selected segment, while the autonomous vehicle (103) is navigating along the planned navigation path;
determine a counter angular velocity corresponding to the current vehicle condition by comparing the plurality of values with pre-stored values, wherein the pre-stored values are generated based on a trial run of the autonomous vehicle (103) under various predefined conditions of the autonomous vehicle (103); and
correct the velocity of the autonomous vehicle (103), by correlating the velocity with the counter angular velocity, and providing the correction velocity to a navigation module (114) associated with the velocity correcting system (107), for applying the correction velocity to navigate the autonomous vehicle (103) along the planned navigation path.

8. The velocity correcting system (107) as claimed in claim 7, wherein the processor (109) measures the plurality of values corresponding to the current vehicle condition, with respect to wear and tear condition of the autonomous vehicle 103, based on one or more parameters comprising at least one of a speed of the autonomous vehicle (103), a load condition of the autonomous vehicle (103), a slope of the planned navigation path and a curvature of the planned navigation path.

9. The velocity correcting system (107) as claimed in claim 7, wherein the pre-stored values corresponding to the various predefined conditions of the autonomous vehicle (103) are associated with a corresponding counter angular velocity.

10. The velocity correcting system (107) as claimed in claim 7, wherein the processor (109) identifies the plurality of values corresponding to the current vehicle condition using one or more sensors configured in the autonomous vehicle (103).

11. The velocity correcting system (107) as claimed in claim 7, wherein the processor (109) iteratively applies the correction velocity for the selected segment at every predefined cycle time, wherein a number of iterations for the selected segment is determined in real-time.

12. The velocity correcting system (107) as claimed in claim 11, wherein the number iterations is determined based on a speed of the autonomous vehicle (103) and length of the selected segment.
