Abstract
In a preferred embodiment, the present invention relates to automatic vehicle control systems for controlling individual wheel torque and steering angle. Control is provided in response to desired forward velocity, desired steering angle, actual angular velocities of each controlled wheel, actual vehicle yaw rate, and actual vehicle lateral acceleration. A command processor uses desired forward speed, desired steering angle, and lateral acceleration to compute command angular velocities for each drive wheel and the commanded vehicle yaw rate. Further, the command signal processor monitors a tire adhesion limit. If this limit is exceeded, command signal will be reduced.
