Abstract
A method and apparatus for providing regenerative and friction braking on a vehicle having one or more wheels driven by a drive motor includes a master cylinder (28), a hydraulic control unit (30), a brake control unit (38), a drive motor control unit (52) and a drive motor (18). The drive motor control unit determines a coast down regenerative torque signal in response to an acceleration signal and a driver brake command regenerative torque signal in response to a pressure signal and a drive motor deceleration signal and commands the drive motor to regeneratively brake the driven left and right wheels in response thereto, thereby providing a desirable proportioning of front to rear braking.
