    摘要: In traffic-related stationary phases, a drive ratio of the transmission remains engaged with the engine running on a road vehicle equipped with automatic transmission. The service brake automatically remains activated for a short time after the vehicle has come to a halt as a result of a targeted braking operation. Thereby, the driver is allowed to remove his/her foot from the brake pedal, and the vehicle can be held stationary in a reliable manner on a flat or sloping road surface. This holding braking mode of the vehicle service brake system is cancelled when the driver actuates the accelerator pedal whose position is monitored by a switch.

    摘要: A brake-pressure control device is provided for a road vehicle with electrohydraulic multi-circuit brake system. For each wheel brake, a hydraulic servo-cylinder is driven by an electric motor. The servo-cylinders enables certain functions to be implemented, namely spot braking mode, including electronic control of the VA/HA braking force distribution (EBKV); anti-lock braking control (ABS function); traction control (TCS function); and vehicle movement control as a result of automatically controlled increase in brake slip at one or more of the wheels of the vehicle. A desired-value setting unit with a single-circuit master cylinder is provided which, in normal electronically controlled braking mode, serves as a desired-value transmitter and, in the event of failure of the vehicle's electronic system, can be activated as an emergency braking unit for building up brake pressure in the front-wheel brakes.

    摘要: A method for terminating an automatic braking process improves an automatic braking process by assuring that reliable termination of the braking process always takes place. Breaking-off criteria, which are independent of the actuation force of the brake pedal, are provided for the automatic braking process. The variables relating to the dynamics of vehicle movement or the activation time of the automatic braking process, if appropriate also as a function of variables relating to dynamics of vehicle movement, are used as the breaking-off criteria. Thus, automatic braking process is terminated as a function of vehicle behavior. In addition, the gradient of the braking pressure is determined as a function of the activation time and/or as a function of the switch-off criteria when the automatic braking process is terminated.

    摘要: In a brake-pressure control device for a road vehicle, having an antilock braking system whose braking device comprises a vacuum brake power assist unit which has a vacuum chamber connected to the intake stub of the vehicle engine and a working chamber which can be subjected to a higher pressure via a control element operable by the brake pedal, a position sensor is provided which detects the position of the brake pedal and generates output signals. An electronic control unit processes these signals and generates drive signals for a brake-pressure control device making it possible to couple into the wheel brakes a higher brake pressure than would otherwise correspond to the instantaneous pedal position. Such driving of the brake-pressure control device is triggered when the speed .PHI. at which the brake pedal is operated overshoots a prescribed threshold value .PHI..sub.s. The brake power assist unit is provided with a solenoid valve arrangement which can be moved from a basic position in which pressure compensation can be performed between the vacuum chamber and the working chamber of the brake power assist unit, whereas the working chamber thereof can be connected only via the control element to the outside atmosphere, into a functional position in which the working chamber is subjected to the ambient pressure but is blocked off from the vacuum chamber.

    摘要: A brake-pressure control device for a road vehicle with a hydraulic brake system has a pneumatic brake booster provided with a change-over device which changes over the brake booster to a mode with an increased boost factor when the speed with which the driver actuates the brake pedal exceeds a threshold value. A reaction piston of the axial force-transmission train, leading from the brake pedal via the reaction piston, a flexible reaction element and the driving piston of the brake booster to the master cylinder, is constructed in two parts. One of the two part-pistons engages axially on the reaction element and the other of the part-pistons acts as a valve element of the inlet valve and via which the driving chamber of the brake booster can be exposed to the ambient pressure. The two part-pistons have complementary threads which engage one another. The pedal-side part-piston can be driven by a device on an electric motor with the effect of shortening the total length of the reaction piston and is activated in the direction of rotation when the actuating speed of the brake pedal is higher than the threshold value.
