Abstract

System for controlling yawing moment in a vehicle equipped with ABS and rear wheel steering includes a controller which generates a compensation steering angle for the rear wheels based on the difference between brake pressures at the front wheels. The difference is filtered so that the angle is zero up to a minimum pressure threshold and thereafter consists of a constant portion added to a variable portion which decreases with time. The compensation steering angle so generated may be modified by a correction factor dependent on the transverse acceleration of the vehicle and a further correction factor dependent on the velocity.
