Embodiment Construction

[0030] Commercial vehicle 1 according to figure 1 With electropneumatic braking system 2. Furthermore, the commercial vehicle 1 has a front axle VA with a left front wheel VA-1 and a right front wheel VA-r, and a corresponding rear axle HA with a left rear wheel HA-1 and a right rear wheel HA-r, wherein , for example in a conventional manner, double tires can be mounted on the rear axle HA.

[0031] The electropneumatic braking system 2 has a central electronic brake control unit 3 (ECU-EBS), a brake pedal 4 for operation by the driver, and actuation of the left front brake cylinder 6-1 and correspondingly for actuating the front axle brake module 5 of the right front brake cylinder 6-2 via the right front ABS shut-off valve 7-2; The rear axle brake module 15 of the brake cylinder 6-3 and the right rear brake cylinder 6-4.

[0032] The more detailed construction of the brake modules 5 , 15 and the brake cylinders 6 - i , ie 6 - 1 , 6 - 2 , 6 - 3 and 6 - 4 can be realized diff...

Abstract

The invention relates to an electropneumatic brake system (2) for a utility vehicle (1), having wheel rotational speed sensors which are divided into two wheel rotational speed sensor groups (14A, 114A, 214A, 314A) that are read by a central brake controller or a second brake controller. In a braking operation, the central brake controller controls the wheel brakes and allows a slip control operation. If the central brake controller malfunctions, the second brake controller controls the wheel brakes and allows an alternative slip control operation.

Description

technical field [0001] The invention relates to an electropneumatic braking system for commercial vehicles. Background technique [0002] Service brake systems, in particular electronic brake systems (EBS), usually have a central electric brake control unit, which can control the braking process at the front and rear wheel brakes by outputting electric service brake signals. In this case, the use of a second brake control device or auxiliary control device is partly provided, which can maintain an auxiliary or at least redundant braking operation or The service brakes operate, which is also known as a fail operable brake system (FOBS). [0003] During normal braking operation, the central brake control can usually carry out brake slip control on the individual wheel brakes. However, such brake slip adjustment is generally no longer possible in fail-operable braking operation. [0004] EP 0 133 287 B1 describes a hydraulic automatic braking system in which a wheel speed se...
