Abstract: A steering control system executes an automatic intervention in the steering of the rear axle when a .mu.-split condition is detected, in order to stabilize the tracking of the vehicle. The steering always takes place in the direction of the vehicle side on which the higher braking torque is generated; this applies also to cornering, irrespective of whether the lower .mu.-value is on the inside of the bend or on the outside of the bend and, furthermore, irrespective of whether the vehicle is being braked or accelerated.

Abstract: An antilock brake system includes a pressure modulator having a step piston. The smaller step defines a primary chamber connected to the wheel brake and the larger piston step defines a driving pressure space that is alternatively connected to the high pressure output of an auxiliary pressure source or to its unpressurized storage reservoir by a control valve. By the admission of pressure to the driving pressure space, the modulator piston, against the restoring force of a strong restoring spring, is forced into its initial position corresponding to the minimum volume of the primary chamber. For a pressure reduction phase, the driving pressure space is connected with the storage reservoir of the auxiliary pressure source, so that, under the combined effect of the brake pressure in the primary chamber and of the restoring spring, the piston moves to expand the volume of the primary chamber. The pressure buildup phases are controlled by the readmission of the output pressure of the auxiliary pressure source to the driving pressure space. The maximum volume expansion of the primary pressure space is smaller than the brake fluid volume that, during a braking taking place with maximum actuating force, can be displaced into the wheel brakes. This avoids the brake unit from becoming "controlled empty" in the case of very low adhesion coefficients between the road and the vehicle wheels.

Abstract: An installation for the forward drive regulation acting on the output torque of a drive aggregate in motor vehicles with a regulating circuit responding to the slippage of each driven wheel on which is superimposed a regulating circuit responding to exceeding an acceleration threshold value of each driven wheel which replaces the slippage regulating circuit designed for optimum traction from the regulation beginning for a predetermined duration and as a result thereof rapidly stabilizes the vehicle because only a small excess torque which can be controlled in few regulating cycles, can occur owing to the early regulation beginning.

Abstract: An anti-skid brake system has a first brake circuit (I) terminating at two wheel brakes and connected to a dual-circuit master cylinder, a brake pressure modulation valve assembly and a recirculating pump. In an anti-skid situation, in order to reduce brake pressure, fluid is withdrawn from the two wheel brakes by the brake pressure modulation valve assembly and then returned to the master cylinder by the recirculating pump. Associated with a second brake circuit (I), which is likewise connected to the master cylinder and which terminates at two other wheel brakes, is a floating piston assembly connected to the first brake circuit (I). In an anti-skid situation, a pressure reduction, which is performed in the first brake circuit (I) by the brake pressure modulation valve assembly brings about a pressure reduction in the second brake circuit (II), via the floating piston assembly.

Abstract: A hydraulic multiple-circuit brake system is proposed, the brake amplifier of which has a multiple-chambered refill container. With an intake connection of its pump, an energy supply apparatus comprising a pump and a reservoir is connected at a predetermined fill level (h/2) to the refill chamber which is intended for the supply of an open brake circuit (II). In this manner, it is attained that if there is an energy failure, the open brake circuit will be capable, as a closed brake circuit, of continuing to function.

Abstract: A brake valve for feeding selectably different levels of fluid pressure into at least one pressure receiver, which is a component of a vehicle brake system. The brake valve includes a first, normally open valve having a ball and a second valve, which is normally closed by a closing spring and which likewise has a ball. The latter ball is pressed by pressure provided by a pressure supply apparatus against a ball seat. A compensation piston acted upon by this pressure is also provided, which presses against the ball in the opening direction of the second valve. Because of the compensation piston, the second valve is easily opened, so that brake pressure can be sensitively controlled.

Abstract: A brake system having a master cylinder including main pistons, a brake booster for displacing the main pistons a brake valve for controlling the brake booster and a pressure supply device. The brake booster has a booster cylinder and a booster piston which is displaceable into the booster cylinder. The booster piston divides a booster chamber from an auxiliary chamber, which is located between the booster piston and the master cylinder. A first valve assembly and a second valve assembly are provided. The second valve assembly is located between the pressure supply device and the brake valve as well as a connection associated with the booster chamber. The first valve assembly is intended for relieving pressure in the booster chamber in favor of a return line or to join it with the pressure supply device. In the anti-skid mode, pressure in the booster chamber is initially reduced by means of the second valve assembly. This is effected by blocking the inflow of pressure medium to the brake valve and by relieving pressure in the booster chamber. If the drop in brake pressure attainable thereby should be inadequate, then by means of the first valve assembly, pressure medium is directed out of the pressure supply device into the auxiliary chamber. This pressure displaces the booster piston toward its initial position. As a result, a pressure drop down to zero is possible, no matter how severely a brake pedal coupled with the brake valve is depressed.
