    • A method for calculation of the lateral force in a motor vehicle with an electromechanical or electrohydraulic steering system is disclosed. The method comprises the following steps: firstly a steering column force is recorded, from which a total restoring torque is calculated. The total restoring torque comprises restoring torques generated by differing forces acting on the wheels. Said restoring torques include a restoring torque generated by lateral force and other restoring torques. The other restoring torques are quantitatively determined on the basis of measured values and subtracted from the total restoring torque, in order to determine the restoring torque generated by lateral force. Finally the lateral force is determined from the restoring torque generated by the lateral force.

    • The invention relates to a method for assisting an operator of a vehicle in the vehicle stabilization, wherein an additional steering torque is applied to the steering line of the vehicle. The method manifests itself by the feature that a first component of the additional steering torque is determined depending on a steering angle difference between an instantaneous steering angle at steerable wheels of the vehicle and a nominal steering angle, and the steering angle difference is determined depending on a difference between an instantaneous value of a yaw rate of the vehicle and a value of a reference yaw rate, and with the value of the reference yaw rate being established in a vehicle model by way of a value of at least one variable predefined by the driver. The invention further relates to a device which is appropriate for implementing the method.

    • A brake system for motor vehicles with an adjustable pneumatic brake force booster includes a control valve which can be actuated by an electromagnet independently of the driver's actions. A brake pressure controller generates signals which serve to actuate the electromagnet. In order to be able to implement a quick-action, low-noise pressure regulating system at low cost, the brake pressure controller (8) is formed by connecting in parallel an electromagnetic control circuit (60) that processes the nominal brake pressure signal (Pnominal) into a first current value (IA) and a regulating circuit (70) that processes a control difference (&Dgr;P) formed from the nominal brake pressure signal (Pnominal) and the actual pressure signal (Pactual) into a second current value IB, with the output variable (Inominal) of the brake pressure controller (8) being formed by adding together the two current values (IA, IB).

    • The invention concerns a process for shortening the braking distance of a vehicle equipped with a brake servo unit which during a standard braking action is only triggered by the brake pedal pressure caused by the driver and in case of a critical driving situation is so triggered by a control device that in comparison to the standard braking action an increased amplification factor is set at the brake servo unit. The invention distinguishes itself by the fact that a danger potential is determined, stating the probability that the vehicle to be braked will be involved in an accident and that the increase of the amplification factor is controlled in accordance with the danger potential.

    • The present invention relates to a maneuvering assistance system for automotive vehicles and a method of maneuvering automotive vehicles which permit a simple and safe maneuvering of the automotive vehicle particularly during a parking procedure. The present invention is especially advantageous when the automotive vehicle needs to be maneuvered, for example, on a steep positive or negative gradient. According to the present invention, a preselected or adjustable maneuvering speed is chosen such that the driver is not surprised by unwanted reactions of the automotive vehicle. The present invention especially comprises an accelerator pedal sensor [(5)] for detecting an accelerator pedal position [(&agr;)] and a device for determining a speed [(vref)] of the vehicle. By using values pertaining to the accelerator pedal position [(&agr;)], to the accelerator pedal depression speed [({dot over (&agr;)})], and the vehicle speed [(vref)], a control unit [(4)] determines whether the vehicle is in a maneuvering or parking condition, in order to accordingly actuate an engine [(6)] or a brake control system [(3)] so that the vehicle [(1)] is moved at a desired maneuvering speed.
