Embodiment Construction

[0070] exist figure 1 A vehicle 100 with a braking system 1 that can be braked via service brakes 3 on wheels 4 in two service brake circuits 2 a, 2 b is shown schematically in FIG. The front axle service brake circuit 2a is assigned to the front axle 6a, and the rear axle service brake circuit 2b is assigned to the rear axle 6b. Additional axles can also be provided, to which service brake circuits 6a and 6b or additional service brake circuits are assigned. Pressure medium accumulators 5a, 5b are respectively assigned to the service brake circuits 2a, 2b depending on the bridge.

[0071] A parking brake circuit 7 is also assigned to the rear axle 6b, wherein the wheels 4 on the rear axle 6b can be braked in the parking brake circuit 7 via a spring-loaded brake 8 so that the wheels of the rear axle 6b can be braked. It is possible to decelerate not only via the service brake 3 in the rear axle service brake circuit 2b, but also via the spring-loaded brake 8 in the parking b...

Abstract

The invention relates to an electronically controllable braking system (1) having an inverter control valve (15; 15a) configured to generate and output an inverter control pressure (pI), wherein the inverter The control pressure (pI) is inversely proportional to the parking brake pressure (pPH) and / or the parking brake control pressure developed in the parking brake circuit (7), which are regulated to In (7), the braking preset parameters (VA, VB, VP) are implemented via the spring energy storage brake (8). According to the invention, it is provided here that if the brake presetting is carried out electrically controlled via at least one service brake circuit (2a, 2b) by the service brake control module (10) of the service brake circuit (3) parameters (VA, VB, VP) are blocked, then the service brake pressure (pBa, pBb) is regulated depending on the inverter control pressure (pI) generated by the inverter control valve (15; 15a) for driving A service brake (3) in at least one service brake circuit of a brake system (1) is controlled.

Description

technical field [0001] The present invention relates to an electronically controllable braking system and a method for controlling an electronically controllable braking system. Background technique [0002] The braking system in a vehicle, preferably a commercial vehicle, can be provided with two or more service brake circuits and a parking brake circuit in which the service brakes that are actuated to the service brakes are adjusted. Brake pressure, in the parking brake circuit, the brake pressure of the parking brake that is regulated to the spring-loaded brake is adjusted. The control of the service brake braking pressure to the service brake is carried out, for example, via a pressure modulator, which is based on a service brake braking specification in the form of a pneumatic service brake control pressure or an electric service brake control signal. The service brake pressure is output to the respective service brake. [0003] In normal operation, the pre-specificat...
