Abstract
Systems, methods, and other embodiments described herein relate to detecting a false positive request to disengage a vehicle control system. In one embodiment, a method includes detecting a false positive request to disengage a vehicle control system based on a difference between a road wheel angle input and an angle of a road wheel controlled by the road wheel angle input and preventing the vehicle control system from disengaging based on detecting the false positive request.
Claims20
A method comprising:
- detecting a false positive request to disengage a vehicle control system based on whether:
- a rate of change of angle of a road wheel exceeds a predetermined threshold value, the road wheel being controlled by a road wheel angle input;
- and
- a difference between the road wheel angle input and an angle of the road wheel exceeds a second predetermined threshold value;
- and
- preventing the vehicle control system from disengaging based on detecting the false positive request.
A system comprising:
- a processor;
- and
- a memory storing machine-readable instructions that, when executed by the processor, cause the processor to:
- detect a false positive request to disengage a vehicle control system based on whether:
- a rate of change of angle of a road wheel exceeds a predetermined threshold value, the road wheel being controlled by a road wheel angle input;
- and
- a difference between the road wheel angle input and an angle of the road wheel exceeds a second predetermined threshold value;
- and
- prevent the vehicle control system from disengaging based on detecting the false positive request.
A non-transitory computer-readable medium including instructions that when executed by a processor cause the processor to:
- detect a false positive request to disengage a vehicle control system based on whether:
- a rate of change of angle of a road wheel exceeds a predetermined threshold value, the road wheel being controlled by a road wheel angle input;
- and
- a difference between the road wheel angle input and an angle of the road wheel exceeds a second predetermined threshold value;
- and
- prevent the vehicle control system from disengaging based on detecting the false positive request.
