Vehicle brake system having adaptive torque control |
摘要 |
A vehicle brake systems (10) is provided which compensates for brake pedal feel variation to provide enhanced braking feel. The brake system (10) includes a brake pedal (18), a wheel sensor (20), and a database (16) for storing target accelerations and torque to pressure parameters. The brake systems (10) may employ a friction brakes (26) and regenerative brakes (29). The brake system further includes a controllers (12) for controlling the amount of braking, including the friction brake actuator (24). The controller (12) determines brake acceleration caused by braking torque and determines a target acceleration based on the driver commanded input. The controller (12) 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.
