Abstract

In a method and apparatus for stabilizing running of a wobbling trailer towed by a vehicle, a tandem of trailer and vehicle is braked by a brake device activated by a control device. The braking process is triggered, when an amplitude of the oscillation of the trailer exceeds a predetermined value. As a result, the tandem is decelerated to a speed at which the amplitude of the oscillation of the trailer falls below a predetermined value. The tandem is decelerated more intensely in the case of a wobbling trailer and when travelling at a first travelling speed than in the case of a wobbling trailer and when travelling at a second travelling speed which is lower than the first travelling speed, and the tandem is braked in presence of the first driving speed during exceeding a lower value of the amplitude than in the presence of the second driving speed.
