Abstract
A system for controlling the yaw rate of a vehicle is provided. The system includes a facility for measuring the yaw rate, the lateral acceleration and the reference velocity of the vehicle. The velocity of the side slip angle of the vehicle is determined according to the equation: ##EQU1## where .beta. is the velocity of the side slip angle, a.sub.trans is the lateral acceleration, .nu. is the reference velocity, .gamma. is the yaw rate, .nu. is the time derivative of the reference velocity, and .beta. is a side slip angle. The velocity of the side slip angle determining mechanism includes a mechanism for setting the value of the time derivative of the reference velocity to zero, and a mechanism for determining the side slip angle by integrating the velocity of the side slip angle.
