Enhanced regenerative braking control method for brake booster pressure build-up delay compensation
Abstract:
A regenerative braking control method. An illustrative embodiment of the method includes selecting a vehicle speed at onset of transition from regenerative braking to friction braking of a vehicle, comparing the vehicle speed to a threshold value, applying a delayed regenerative braking torque ramp out to a hybrid powertrain and sending an undelayed regenerative braking torque ramp-out signal to a vehicle brake controller without at onset of transition from regenerative braking to friction braking of the vehicle if the vehicle speed falls below the threshold value.
