The present disclosure relates to a method for controlling an application of regenerative brake torque to a plurality of wheels of at least one of a hybrid electric vehicle or an electric vehicle, to avoid brake instability. The method may involve sensing variables such as an angle of a steering wheel of the vehicle, a speed of the vehicle, a brake pedal rate as an operator engages a brake pedal, and a wheel slip of each of the front and rear wheels. A commanded lateral acceleration may be determined representing a steady state lateral acceleration that the vehicle would reach at an actual vehicle speed and with a presently sensed steering wheel angle. The application of regenerative brake torque can then be controlled based on the sensed wheel slips relative to at least one predetermined wheel slip limit. The predetermined wheel slip limit is determined based at least in part on the determined commanded lateral acceleration.

System and method for delimiting regenerative braking

An enhanced stability control system () for a vehicle includes a vehicle status sensor that generates a sensor signal. A driver input sensor that generates an input signal. A controller () may disable normal yaw stability control operation and enable body-force-disturbance (BFD) yaw stability control (YSC) operation, which includes at least partially reducing response functions of the normal yaw stability control associated with the input signal, in response to the sensor signal and performing BFD-YSC functions to achieve desired control performance upon the detection of BFD reception. The controller () may also or alternatively compare the sensor signal to a threshold and detect an improperly functioning/inoperative vehicle status sensor. The controller () disregards information associated with the improperly functioning/inoperative vehicle status sensor, and continues to perform enhanced yaw stability control operations.
