Abstract
A system is specified for the automatic adjustment of a gap between a tractor vehicle and an attached trailer, with a length-adjustable hitch with a tension tube, at the end of which is arranged a tension lug, while the tension lug can travel in the vehicle's lengthwise axis relative to the tension tube by an actuator along a predetermined travel path, as well as a control unit. The basic problem of the invention was to provide a system with which the gap between tractor vehicle and trailer can be changed automatically in driving operation and depending on the speed, both for articulated and unarticulated trailers. The problem is solved according to the invention with a system in which the control unit is an electronic controller, which is hooked up to a speed pickup for the processing of a speed signal and connected to the actuator.
