ABSTRACT:
An active brake control method including an improved method of developing the desired state variables, enabling the system designer to specify the damping ratio and the un-damped natural frequency of desired vehicle performance. The desired state variables are determined by converting a linear time domain model into a transfer function model and solving for the lateral velocity and yaw rate as a function of the driver steering angle, the damping ratio, the un-damped natural frequency of the vehicle, and the transfer function zeros. The damping ratio, the un-damped natural frequency of the vehicle, and the transfer function zeros may either be computed or specified in a look-up table as a function of vehicle speed. This allows the system designer to provide increased damping at high vehicle speeds, for example.
