Abstract
A vehicle brake systems ( ) is provided which compensates for brake pedal feel variation to provide enhanced braking feel. The brake system ( ) includes a brake pedal ( ), a wheel sensor ( ), and a database ( ) for storing target accelerations and torque to pressure parameters. The brake systems ( ) may employ a friction brakes ( ) and regenerative brakes ( ). The brake system further includes a controllers ( ) for controlling the amount of braking, including the friction brake actuator ( ). The controller ( ) determines brake acceleration caused by braking torque and determines a target acceleration based on the driver commanded input. The controller ( ) also determines a brake acceleration error as the difference between the target acceleration and the brake acceleration. The controller adjusts the torque-related parameter to reduce the brake acceleration error by adjusting the braking torque generated by the friction brake actuator to compensate for brake torque variation.
