An ABS which evaluates slip values prescribes pressure values for the wheel brakes. In order to improve the driving stability, these pressure values are varied by a brake controller using the deviation of the yawing speed from a set value and the front-axle steering angle as input variables. The brake controller determines its output values (variation values) with the aid of the fuzzy logic. Additionally, rear-axle steering is integrated into the system, the system partially also using fuzzy logic. Subsequently, an adaptation which is based on fuzzy logic and uses the brake controller and the rear-axle steering controller in a weighted fashion is proposed.
