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
[0021] figure 1An 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 .
[0022] 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 a...

The invention relates to a method for decelerating a trailer vehicle (4), wherein wheel brakes (9) on the trailer vehicle (4) are actuated pneumatically using trailer brake pressure (14) so that the tendency of a trailer vehicle without ABS brakes to skid or push against the vehicle in front in a vehicle combination (5) during a braking process can be counteracted using simple vehicle equipment. According to the invention a wheel module (18) on one or more wheels (7) of the trailer vehicle (4) measures acceleration values for the wheel (7) concerned, generates an information signal (21) on thebasis of the measured acceleration values and transmits said information signal wirelessly. The measured acceleration values are analysed and monitored for a tendency to lock up and, on receipt of aninformation signal (21), an electronic brake control unit (34) adjusts the trailer brake pressure (14) on the basis of the information signal (21). The invention further relates to a wheel module (18) for performing the method and a vehicle combination (5) having a towing vehicle (2) and at least one trailer vehicle (4).
Description
technical field [0001] The invention relates to a method for decelerating a trailer according to the preamble of claim 1 . According to claim 8, the invention also relates to a wheel module for carrying out the method. The invention also relates to a vehicle combination with a motor vehicle and at least one trailer according to the preamble of claim 11 . 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 b...
