The invention relates to an electronically regulated brake system comprising a central control device (Z ; Z ) and at least one pressure control valve (A). According to the invention, the electronically regulated brake system additionally includes at least one pressure regulating valve (B) and/or at least one pressure regulating module (C).

Electronically regulated brake system

An electrically controlled braking system for a vehicle is proposed, in which at least one actuating variable for the service brake and one actuating variable for a parking-brake request are received by a central control unit, the variables, or variables derived therefrom, being transmitted separately via a communication system to wheel modules actuating at least one wheel brake.

Electrically controlled braking system for a vehicle

In a vehicle having a duty brake and a sustained-action brake (retarder), the actual braking moment produced by the sustained-action brake, as well as the braking command of the driver, are taken into consideration in the electrically controlled adjustment of the duty brake.

Method and apparatus for controlling the brake system of a vehicle

A central control module generates nominal values for braking based on a pedal input value form a pedal sensor which detects actuation of the brake pedal by the driver, and sensor signals representing wheel speeds. First and second brake control modules transmit sensor signals to the central module, receive nominal values from the central module, and transmit nominal values to the actuators. The first brake control module receives the pedal input value from the pedal sensor directly, and calculates the nominal values as a function of the pedal input value when the central module has failed.

Method and device for electrically controlling or adjusting the brake

An electronic control unit adjusts the pressure in the brake cylinders of at least one axle during the braking process on the basis of measured static and dynamic loads at the other axle.

Process and apparatus for controlling the brake system of a vehicle

In a selected operating situation, the automatic control circuit, which is closed during normal operation, is opened, the final control element of the wheel brake being actuated within the scope of an open-loop control process. The drive signal value for the wheel brake changes in accordance with a predetermined time function, and the application pressure or release pressure is found on the basis of the characteristic behavior of a value representing the braking action.

Method and apparatus for determining a characteristic value of a wheel

An operating variable detected by at least two control units for actuating the brakes is distributed to a central control unit which identifies an error state in the area of the control unit in question when the operating variable in question deviates unacceptably from a reference value.

Process and device for testing the function of an electronically

A method operating a braking system to prevent or overcome glazing of the brake linings. The brake system has a friction-affected service brake and a wear-free auxiliary brake. A brake value, for instance vehicle deceleration, can be specified to the brakes by a brake value transducer. On the specification of the brake value transducer signals, a control unit triggers the brakes; it detects and evaluates signals characterizing the braking action. Upon a request for braking, the control unit preferentially triggers the auxiliary brake. If the brake value transducer signal level is high, it additionally switches on the service brake. The control unit detects the number of braking events of the service brake and their intensity (duration, action, etc.). As a function of these data, the control unit detects a threatening danger of glazing or glazing that has already begun and triggers the service brake exclusively. The brake linings of the service brake undergo 'deglazing' by braking, by way of an adequate temperature rise.
