ABSTRACT:
An improved active brake control in which differential braking is used in a feed-forward control to develop vehicle yaw in response to a desired yaw value determined as a function of steering wheel position and vehicle speed. The desired yaw rate value is used to develop a derivative yaw component and a proportional yaw component, which are summed to form a feed-forward yaw command for differential braking. Both proportional and derivative components have limited control authority determined by dead-band and saturation thresholds, and the proportional term is subjected to a diminishing integrator which reduces the yaw command as the desired yaw rate value approaches steady-state.
