Abstract
Direct sensing of rough road conditions are used to modify operation of a wheel slip control system. At least one suspension sensor () senses an operating parameter of the suspension system. A road surface classifier is responsive to the suspension pension sensor () for generating a road surface signal representing a roughness of a road surface over which the vehicle travels. A braking system includes a wheel speed sensor and a brake actuator. An active braking control detector wheel slip in response to the wheel speed sensor () during at least one of braking or accelerating of the vehicle and modulates the brake actuator in response to the detected wheel slip. The active braking control is responsive to the road surface signal for modifying modulation f the brake actuator as a function of the road surface signal.
