Problems solved by technology
Especially in the case of vehicle combinations with full trailers or central axle trailers, the distribution of the load on the tractor or trailer is often unclear in the case of partial loads, which likewise makes it difficult to determine the appropriate trailer brake pressure. adjustment becomes difficult or impossible
In this context, estimation of proper trailer brake pressure is often very difficult

Embodiment Construction
[0024] figure 1 An electro-pneumatic diagram of the tractor 2 , ie the braking system 1 of the commercial vehicle and the braking system 3 of the trailer 4 is shown. The tractor 2 and the trailer 4 form a vehicle combination 5 in which the tractor 2 is equipped with a motor and pulls the trailer 4 . The braking system 3 of the trailer vehicle 4 is activated in the manner described below for the braking of the braking system 1 of the tractor 2 .
[0025] Both the wheels 6 of the tractor 2 and the wheels 7 of the trailer 4 are each assigned pneumatically actuatable wheel brakes 8 , 9 . The wheel brakes 8 , 9 decelerate the wheels 6 , 7 assigned to them under the action of brake pressure. In the braking system 1 of the tractor 2 , the regulation of the brake pressure at the respective wheel brake 8 is monitored by the brake control unit 34 . Each wheel 6 of the tractor is assigned a pressure control valve 10 which can be individually actuated by a brake control unit 34 . Via ...

The invention relates to a method for decelerating a trailer (4), wherein the wheel brakes (9) of the trailer (4) are actuated pneumatically via the trailer brake pressure (14) in order to utilize the low To prevent a trailer without an anti-lock braking system from slipping or moving forward during the braking process onto a vehicle driving ahead in the vehicle combination (5), it is provided according to the invention that one or more of the trailers (4) At each wheel (7), the wheel module (18) receives the acceleration measurements of the respective wheel (7), takes these acceleration measurements into account and generates and wirelessly transmits an information signal (21). Here, the measured acceleration values are evaluated and monitored with respect to the locking tendency, wherein the electronic brake control unit ( 34 ) reacts to the trailer vehicle when receiving the information signal ( 21 ) taking this information signal ( 21 ) into account. brake pressure (14) for matching. The invention also relates to a wheel module (18) for carrying out the method and a vehicle combination (5) having a tractor (2) and at least one trailer (4).
Description
technical field [0001] The invention relates to a method for decelerating a trailer. The invention also relates to a wheel module for carrying out the method. The invention also relates to a vehicle combination comprising a motor vehicle and at least one trailer. Background technique [0002] Modern commercial vehicles with pneumatically actuatable wheel brakes usually have an electronic brake control unit which, inter alia, can bring about a specific adjustment of the brake pressure for driving stability functions. In electronic braking systems (EBS), controls are generated and processed as electrical signals in the control transmission. In this case, an electronic brake system with a three-channel or four-channel system is preferably used, in which the brake pressure of the individual wheels or axles can be adjusted independently of one another. Independently of the electronic brake system (EBS), the brake system can be supplemented with an anti-lock braking system (ABS...
