Lane centering fail-safe control using differential braking
First Claim
1. A method for fail-safe performance of a lane centering system, the method comprising:
- using a computer processor,monitoring an electrical power steering system of a vehicle for a failure; and
switching operation of the lane centering system to a differential braking controller to output differential braking commands to a differential breaking system, upon determining that a failure of the electrical power steering system has occurred,wherein the output braking commands direct the differential braking system to apply force a brake for a wheel of vehicle, such by the applied braking force the vehicle follows a desired path determined for a lane centering operation.

Abstract
Method, system and non-transitory computer-readable medium for fail-safe performance of a lane centering system. An electrical power steering (EPS) system of a vehicle is monitored for a failure and operation of the lane centering system is switched to a differential braking controller to output differential braking commands to a differential breaking system upon determining that a failure of the EPS system has occurred, where the output braking commands direct the differential braking system to apply force a brake for a wheel of vehicle, such by the applied braking force the vehicle follows a desired path determined for a lane centering operation.

15. A system for fail-safe performance of a lane centering system, the system for fail-safe performance comprising:
-
a differential braking controller coupled to a differential braking system; and a supervisory element coupled to the differential braking controller and a lane centering system, the supervisory element configured to monitor an electrical power steering system of a vehicle for a failure and, upon determining that a failure has occurred, switch an output of the lane centering system to an output of the differential braking controller, wherein the output of the differential braking controller provides a braking command to the differential braking system for an application of a braking force to a wheel of the vehicle, wherein by the applied braking force the vehicle follows a desired path determined for a lane centering operation. - View Dependent Claims (16, 17, 18)

19. A non-transitory computer-readable medium having stored thereon instructions, which when executed by a processor cause the processor to perform the method of:
-
monitoring an electrical power steering system of a vehicle for a failure; and switching operation of the lane centering system to a differential braking controller, to output differential braking commands to a differential breaking system, upon determining that a failure of the electrical power steering system has occurred, wherein the output braking commands direct the differential braking system to apply force a brake for a wheel of vehicle, such by the applied braking force the vehicle follows a desired path determined for a lane centering operation. - View Dependent Claims (20)
