Embodiment Construction

[0029] exist image 3 A tractor tractor with a tractor 1 and a semi-trailer 2 is schematically shown in FIG. 2 , its semi-trailer 2 being designed here as an example with three axles. Here, the semi-trailer 2 is connected to the traction machine 1 via a saddle coupling 3 , wherein the saddle coupling 3 forms an interface via which the semi-trailer 2 is supplied with electrical energy and compressed air, although this is not detailed here. show. The information signal (signal channel 4a) is then intercepted or derived in the semi-trailer 2 newly coupled to the tractor 1 by means of the saddle coupling 3 configured in this way and supplied to the brake test controller 4, which evaluates the information signal and First identify ( figure 1 ), the new semi-trailer has been connected to tractor 1. Furthermore, it can be deduced from this information signal of the brake test controller 4 which type of semi-trailer and in particular which semi-trailer brake system 5 is involved, w...

Abstract

A method carries out a brake test on trailer vehicles and / or semitrailer vehicles. The method a) senses a semitrailer (2) or trailer which has been newly hitched to the towing vehicle (1), b) initializes an on-board brake test for the semitrailer brake system or trailer brake system (5), c) initiates at least one defined braking process by the semitrailer brake system (5) or trailer brake system after a defined distance has been traveled, and d) senses and determines the braking effect of the at least one defined braking process as a braking effect actual value which is compared with a braking effect setpoint value which is present, and e) an information signal is output which takes into account the evaluation result of the step d).

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for performing a brake test on a trailer vehicle and / or a semi-trailer vehicle. Furthermore, the invention relates to a device for carrying out such a method according to the preamble of claim 15 . Background technique [0002] Depending on the purpose of use, the commercial vehicle is used either as a stand-alone car or in a car combination. In this case, a vehicle combination is understood to mean a trailer or tractor with a trailer or semi-trailer, wherein such trailers are generally known as articulated towbar trailers or central axle trailers, for example. Semi-trailers are mainly used in the form of saddle tractors (Sattelkraftfahrzeug). Especially at peak times (in which high loads of the vehicle fleet occur) it can occur that, if necessary, an old trailer or semi-trailer is used to cover the load peak, the brakes of which do not function properly because, for example, A r...
