Abstract

In a control system for a train composed of a towing vehicle and a trailer, the towing vehicle is equipped with an electronically actuatable drive train. A trailer steering angle actual value sensor determines a trailer actual steering angle of a wheel axle which steers the trailer. The driver of the vehicle can input a trailer setpoint steering angle via a trailer steering angle setpoint value sensor. A reversing device is provided which determines, from the trailer actual steering angle and the trailer setpoint steering angle, a modified towing vehicle setpoint steering angle of a wheel axle which steers the towing vehicle. In the active state of the reversing device, the modified towing vehicle setpoint steering angle takes the place of the present towing vehicle setpoint steering angle in a modified movement vector; and when the train is moving, it changes the trailer actual steering angle into the trailer setpoint steering angle when the modified movement vector is processed.
