Embodiment Construction

[0020] figure 1 (a) shows an arrangement according to the prior art. Thus, for example, the electronic brake system EBS 2 is coupled to the brake system 1 . Inside the brake system 1 is a separate electronic assembly 101 which is arranged to provide a protective mechanism. The brake system 1 is connected to the EBS via a pipeline 102, which controls the brake system.

[0021] figure 1 (b) shows a simplified block diagram of the device according to the invention. The actuating device 3 is coupled to an electronic braking system 2 (EBS). In the electronically adjusted braking system, the driver gives the braking command electronically, and the braking command is converted into a control signal in the electronic component, which is used to control the braking system controlled by the pressure medium (air, hydraulic pressure). Usually, the components of the valve to be controlled are also located in the spatial proximity of the electronic assembly. Electronically adjusted br...

Abstract

The invention relates to a device for protecting against unauthorized removal of a trailer, with an electronic brake system (EBS) and a brake assembly, characterized by a control device which is set up in order to be actuated to activate and deactivate the protection such that the electronic brake system is activated so as to bring about protection by means of the brake assembly and thus to brake the trailer by means of the brake assembly if unauthorized removal is attempted.

Description

technical field [0001] The invention relates to a device for preventing unauthorized removal of a trailer vehicle. Background technique [0002] The simplest known mechanism for preventing theft of a trailer is a catch on the kingpin which makes it impossible to couple the trailer mechanically. But these latches are uncomfortable, expensive and have to be overcome by mechanical action. [0003] Vehicle brake systems are also known which provide anti-theft protection in which a valve is arranged in the pressure medium line which reduces the pressure in the line carrying the pressure medium in order to engage the brake . Known mechanisms combine the function of a valve, for example, with the actuation of a key, so that the parking brake is only released when a corresponding key actuation takes place. The disadvantage here is that in order to unlock the parking brake, a suitable key must be in the hands of the person who wants to remove the trailer. Therefore, conventional ...
