A steering system is provided for motor vehicles, in which, during the normal operation, the driver adjusts an actual steering angle value generator by way of a steering handle. A control and automatic control arrangement correspondingly operates the steered vehicle wheels by a motor-operated adjusting assembly. For an emergency, a forced coupling is provided between the steering handle and the steered vehicle wheels which switches on automatically. This forced coupling is constructed such that a centering mode can be switched on, during which, when the forced coupling is at least partially switched off, the manual steering wheel can be adjusted until a position is reached. Thereby, in the straight-ahead position of the steered vehicle wheels, the manual steering wheel takes up a defined normal position.

The invention relates to a method for controlling vehicle brake pressure as a function of the deviation of the actual slip of wheels relative to a prescribed desired slip. The desired slip is determined from the wheel speeds in such a way that the cornering forces occurring between wheel and roadway given the specific desired slip values and the adhesion conditions occurring, ensure stable handling.

A method for controlling propulsion in motor vehicles is described which detects when the vehicle approaches the limiting value for lateral acceleration independently of the condition of the load, the tires, the roadway and so forth in that a measurement value for the lateral acceleration, the yaw velocity or the difference of the front wheel speeds of rotation is compared with a mathematical value determined by the use of a mathematical formula, in which method this mathematical value is phase-delayed in a filter and corrected in a first correction unit and the mathematical formula used is corrected in a second correction unit.

Method and device for controlling propulsion in motor vehicles

A propulsion control system for motor vehicles for maintaining stable driving conditions, having a computer unit for determining a desired value or a tolerance range for the rotational speed difference of the front wheels or of the lateral acceleration or of the yaw velocity, and having a comparator unit in which this desired value or tolerance range is compared with the measured actual value, in which case the difference between the actual value of the desired value or tolerance range is used as a control signal for the brakes of the wheels and/or for a power control element of the vehicle engine.
