Abstract

The invention relates to an electronically controllable brake system (1) having an inverter control valve (15; 15a), which is designed to generate and output an inverter control pressure (pI), whereinthe inverter control pressure (pI) is inversely proportional to a parking brake braking pressure (pPH) generated in a parking brake circuit (7) and / or a parking brake control circuit, which are to beactuated in order to implement a braking specification (VA, VB, VP) in the parking brake circuit (7) via spring-loaded brakes (8). According to the invention, an operating brake braking pressure (pBa, pBb) is to be actuated in order to control operating brakes (3) in at least one operating brake circuit of the brake system (1) as a factor of the inverter control pressure (pI) generated by the inverter control valve (15; 15a), if an implementing of a brake specification (VA, VB, VP), controlled electrically by an operating brake control module (10) of the operating brake circuit (3), is prevented via the at least one operating brake circuit (2a, 2b).

Description

technical field

[0001] The 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 regulated to the service brakes are adjusted Brake pressure, in the parking brake circuit, sets the parking brake pressure that is regulated to the spring-loaded brake. The brake pressure of the service brake is regulated to the service brake, 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 electrical service brake control signal. output the service brake pressure to the respective service brake.

[0003] In normal operation, the presetting is carried out electrically via the service ...

Examples

Embodiment Construction

[0063] exist figure 1 A vehicle 100 is shown schematically with a braking system 1 which can brake in two service brake circuits 2 a , 2 b via service brakes 3 on wheels 4 . 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. Further axles can also be provided, to which service brake circuits 6 a and 6 b or further service brake circuits are assigned. A pressure medium store 5 a , 5 b is assigned to the service brake circuits 2 a , 2 b per bridge.

[0064]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 accumulator brake 8, so that the wheels of the rear axle 6b 4 Deceleration is possible not only in the rear axle service brake circuit 2 b via the service brake 3 , but also in the parking brake circuit 7 via the spring accumulator brake 8 . For this purpose, a combi...
