Abstract: Disclosed is a method for controlling a brake system (1) of a motor vehicle having an electric-regenerative brake, in particular a generator (4), and a number of hydraulic friction brakes (2) driven by at least one brake pressure generating means by way of a braking medium (B). The brake system is controlled so that the total deceleration of the brake system is composed of deceleration components of the friction brakes (2) and the electric-regenerative brake, thus achieving maximum brake comfort. The braking medium (B) is discharged into a pressure accumulator (12) when braking with an electric-regenerative brake.

Abstract: The present device relates to a pressure controller, in particular for a slip-controlled brake system in a motor vehicle, which is equipped with a first housing (1) for the accommodation of several pressure control valves and with a second housing (2) arranged on the first housing (1) and accommodating electric and/or electronic components which electrically contact several pressure sensors arranged in a sensor housing (3) when the second housing (2) is placed on the first housing (1), and at least one device is arranged between the sensor housing (3) and the second housing (2) for the compensation of process and assembly tolerances.

Abstract: A braking pressure boosting device is suggested, in particular for automotive vehicles, which includes a boost sensor for sensing or identifying the point of maximum boosting of the braking pressure boosting device. By using the boost sensor, ad signal is generated reporting the point of maximum boosting. This invention permits the manufacture of high-performance braking force boosting devices requiring minimal space and opens up new potential for economizing.

Abstract: To retain a vehicle on an inclined roadway and when starting uphill, the vehicle speed, the brake pedal application, the drive torque, the operating condition of the vehicle engine, the application of a parking brake, and the activation of the retaining system is determined. When the retaining system is activated and the vehicle speed lies below a limit value, the brake force or the braking pressure is maintained when the brake pedal is applied and no drive torque is sensed; the brake force is increased when the driving engine is switched off and neither the brake pedal nor the parking brake is activated, or when the engine is switched on and neither brake pedal application nor drive torque is sensed. The brake force is reduced when the parking brake is applied, with the engine switched off and the brake pedal not applied, or a drive torque is sensed with the engine switched on. The retaining system is deactivated when the vehicle speed threshold is exceeded and/or when the off-switch is activated.

Abstract: A brake pressure controller for a hydraulic vehicle brake system includes a master brake cylinder (1), a wheel brake cylinder (10, 11) connected thereto through a brake conduit (5), and a branch conduit (8, 9) which is provided in the brake conduit (5) between the master brake cylinder (1) and the wheel brake cylinder (10, 11). The brake system includes control valves (12, 14) and a pump (16) returning pressure fluid from a return conduit (15) into the brake conduit (5). At least one valve (6) is provided between the master brake cylinder (1) and the branch conduit (8, 9), which valve, in a first mode of operation, connects the outlet (17) of the pump (16) to the master brake cylinder (1) and, in a second mode of operation, discontinues the connection from the outlet (17) of the pump (16) to the master brake cylinder (1) and connects the inlet (24) of the pump (16) to the master brake cylinder (1) or a reservoir (4).

Abstract: An anti-lock hydraulic brake system is described wherein a throttle valve has a restrictive flow condition which becomes effective in the brake line in the event of brake slip control. Pumps for reapply pressure deliver fluid to the wheel brake via this restriction and regulating the pressure in the wheel brake is performed by control of an outlet valve. The throttle valve is operated hydraulically by various arrangements including the application of pump pressure, or by wheel brake pressure applied upon opening of the outlet valve at the start of an anti-lock control cycle.

Abstract: A hydraulic servo brake system with slip control. Brake circuits (18, 22, 25) with supply valves (28, 32, 35) and discharge valves (29, 33, 36) for the control of the wheel cylinder pressures during slip control are provided. Throttle points (38) are arranged within the supply valves. Each supply valve is bridged by an auxiliary valve (31, 34, 37) which is switchable into the closed position when the slip control action sets in. In this manner, the pressure gradient for the brake pressure build-up in the wheel cylinders is high before the slip control and low during the slip control.
