Problems solved by technology

The "European Trailer Control", which brakes the trailer by means of the service brake via the brake pressure when the spring accumulator is deflated in the de-energized state of the vehicle, is not possible with the arrangement in DE 10 2015 112 490 A1 and Also explicitly not setting
Furthermore, the design of the relay valve with two control pistons in the relay valve is complex

Embodiment Construction

[0062] figure 1 The overall structure is first illustrated in terms of vehicle 500 , which includes a tractor 502 and a trailer 504 . Here, the trailer 504 is only shown schematically, ie only the axle 506 of the trailer 504 is shown. Trailer 504 has a trailer service brake system 508 , shown only schematically, which can be connected to corresponding interfaces 515 , 516 connections. The trailer 504 can be connected to the accumulator 525 via the interface 515 and the brake pressure can be transferred via the interface 516 . Trailer service brake system 508 has service brakes 510a, 510b shown schematically.

[0063] Tractor 502 has braking system 520 with compressed air reserve 521 for rear axle brake circuit 522, compressed air reserve 523 for front axle brake circuit 524, and for trailer braking Third compressed air reserve 525 of circuit 542 .

[0064] A central module 527 is provided as the central and higher-level control unit, which operates purely electrically. T...

Abstract

The invention relates to an electropneumatic trailer control module (1) for an electronically controllable pneumatic braking system (520) of a vehicle (500) having a tractor (502) and a trailer (504), the electropneumatic The trailer control module has: an electronic control unit (ECU), a pneumatic reserve input (11) that can be connected to a compressed air reserve (525), with one or more electropneumatic valves (RV, IV, OV) trailer control valve unit (65), trailer brake pressure port (22), and trailer supply pressure port (21). The trailer control module (1) is characterized in that the electronic control unit (ECU) has a parking brake signal input terminal (200) for receiving electronic braking representative signals (SB1, SB2, SB3), and the electronic braking The representative signal represents the actuation of the parking brake (6, 532a, 532b) of the towing vehicle (502), wherein the electronic control unit (ECU) is set up to At least one valve (IV) of one or more electropneumatic valves (RV, IV, OV) of the control valve unit (65) is switched in order to regulate the brake pressure ( PB). The invention also relates to a vehicle.

Description

technical field [0001] The invention relates to an electro-pneumatic trailer control module for an electronically controllable pneumatic braking system of a vehicle with a tractor and a trailer, the electro-pneumatic trailer control module having an electronic control device, energy and compressed air storage A pneumatic reserve input to which the device is connected, a trailer control valve unit with one or more electro-pneumatic valves, a trailer brake pressure connection, and a trailer supply pressure connection. The invention also relates to a vehicle having an electro-pneumatic trailer control module of the generic type. Background technique [0002] In vehicles, especially commercial vehicles, with a pneumatic braking system, in particular designed as an electronic braking system (EBS) or an anti-lock braking system (ABS), a control unit (ECU) can be used to control the braking pressure. They actuate electro-pneumatic valves, such as relay valves or axle modulators, w...
