Problems solved by technology

However, since there is usually still a ground connection for the power supply of the component, this value or this check cannot detect a faulty contact connection.
[0006] Electromagnetic imbalances can occur especially in the high-frequency-transmission section when the shielding ground of the data cable, which consists of a grounding conductor, is broken

Embodiment Construction

[0019] Electropneumatic brake control device 1 such as figure 1 With central module 2. The central module 2 is used for central data processing and can be connected to other internal vehicle data connections not shown here. In addition, the electropneumatic brake control device 1 has a drive axle-brake pressure modulator (rear axle-brake pressure modulator) 3 for brake pressure regulation on the driven rear axle, a drive axle brake pressure modulator 3 for the front axle Brake pressure modulator 4 for brake pressure regulation on the front axle, additional axle brake pressure modulator 5 for brake pressure regulation on the auxiliary or lifting axle, and as sensor module for electronic control ESP-Module 6 of ESP-Sensing System 6 .

[0020] In the central module 2 a controller area network (CAN) driver 8 is provided for the two controller area network (CAN) buses 9 , 10 . Central module 2 with its controller area network bus 8, additional axle brake modulator 5 with its bus...

Abstract

The invention relates to a vehicle electro-pneumatic type brake control device comprising at least a central mould, a first shaft-brake regulator for regulating brake pressure on the first shaft, a second shaft-brake regulator for regulating brake pressure on the second shaft, an electric data connector between the central mould, the first shaft-brake pressure regulator and the second shaft-brakepressure regulator, wherein a non-central electric data connector between the first and the second-shaft brake regulators has a data conductor and at least one ground conductor. According to the invention, a detection circuit device for at least detecting the non-central electric data connecting ground conductor sends a detection signal to at least one ground conductor and reads and evaluates thesent detection signal.

Description

technical field [0001] The invention relates to an electropneumatic brake control device for a motor vehicle and to a method for monitoring a data connection between two shaft-brake pressure modulators of a motor vehicle. Background technique [0002] The electropneumatic brake system of the truck partly has a plurality of controllers which are combined with one another via a data bus. In this way, in particular brake pressure modulators can be provided for the different axes, which communicate with the central module and possibly with each other. Some use star-quad quad cables for the data bus, with which a ground conductor and a supply voltage conductor wrap around two data or signal conductors or are twisted to one another. In this case, the ground conductor can be routed externally for shielding. [0003] In this case, the data connection is prone to failure. In particular, data connections distributed externally on the vehicle or exposed to environmental influences c...
