    摘要: A method of operation of an electronically controllable brake actuation system for anti-lock automotive vehicle brake systems employs a brake system which includes a master brake cylinder operable by an actuating pedal, braking pressure generators which are electromechanically operable by an electronic control unit. The braking pressure generators are directly connected to wheel brakes of a vehicle and are connectable to the master brake cylinder by way of hydraulic connections closable by valves that are electromagnetically operable by the electronic control unit. The system also includes at least one sensor device for identification of the driver wish for deceleration, and at least one simulator chamber interacting with the master brake cylinder. On commencement of a braking operation, a signal representative of the position of the master brake cylinder piston and a signal representative of the actuating speed occurring on the actuating pedal are produced. A length of the time delay, after which the valves are closed upon commencement of the braking operation, is determined by the electronic control unit responsive to at least one of the signals.

    摘要: An electronically controllable anti-lock brake actuation system for automotive vehicles, including a pedal actuated dual-circuit master brake cylinder, and braking pressure generators actuatable by an electronic control unit. Each of the braking pressure generators has a piston slidable in a cylinder bore from an initial position, each piston separating a first working chamber, to which each one wheel brake of the vehicle is connected directly and the master cylinder is connected by way of a closable hydraulic connection, from a second working chamber and is connected to the master cylinder where the stepped piston is operable to achieve a braking pressure generation or boosting. In one embodiment, first and second electromagnetically operable separating valves are inserted in the connection between the first working chamber and the master brake cylinder, the connection between the master brake cylinder and the second working chamber being effected exclusively by way of the second separating valve, and the initial position of the stepped piston permits a return stroke in opposition to its actuating direction. In another embodiment, no connection exists between the first working chamber and the master brake cylinder. The second working chamber is connected to the master brake cylinder by way of a closable hydraulic connection, and the stepped piston is operable only so as to achieve a braking pressure generation. The closable connection is achieved via an electromagnetically operable valve interposed between the second working chamber and the master brake cylinder, and the connection is open in the valve's first switch position and, in the valve's second switch position, the master brake cylinder is isolated from the second working chamber and a connection is established between the first and the second working chamber. The initial position of the stepped piston permits a return stroke in opposition to its actuating direction.

    摘要: A hydraulic braking system with slip control, comprising a working piston guided within the brake pressure generator, a booster piston of a hydraulic brake force booster for actuating the working piston at least one wheel brake connected to the brake pressure generator and an electrically excitable auxiliary pressure source adapted to be connected to the brake force booster, a control and regulating electronic unit for detecting the wheel rotating pattern and for controlling the wheel braking pressure by pressure modulating valves. An electronic sensor is provided for detecting the relative movement between the pressure rod and the booster piston, the output signals of which are capable to influence the excitation of the auxiliary pressure source. This will permit the brake force boosting, if need be, to be effected independently of actuation forces put in manually, with anti-locking control/traction slip control functions being readily exercisable at any time.

    摘要: The setpoint generator according to the invention utilizes the information "pedal travel s" in combination with the information "pedal force p" by weighting them in input circuits 4,5 and summing up the corresponding partial setpoints p'.sub.s and p'.sub.p to form a setpoint p'.sub.Hz. Here, a countercurrent weighting takes place: If a small force acts on the pedal, the pedal travel is dominant; as the pedal force is growing, the latter is weighted more heavily. In this way, a smooth brake behavior is attained, whereby the comfort is enhanced and the wear of the employed components is reduced.
