Abstract
In order to allow a traffic-lane following device in a vehicle to be used at relatively high vehicle speeds, a steering system is provided with a steering handle and a steering run which couples the steering handle to vehicle steered wheels. A servomotor is coupled to the steering run. A servovalve is arranged in the steering run and has a first control part (which is associated with a section on the steering handle side of the steering run) as well as a second control part (which is associated with a section on the vehicle steered wheel side of the steering run) to operate the servomotor as a function of relative movements between the control parts. An actuating drive is coupled to the section on the steering handle side of the steering run and is used to produce a steering force. A regulating and control arrangement uses a sensor system to determine required steering angle values which allow a traffic lane to be followed and uses a steering angle sensor to determine actual steering angle values. The actuating drive is operated as a function of a comparison of the required and actual steering angles, in which the steering angle sensor interacts with the section on the vehicle steered wheel side of the steering run.
