A first control or regulating device for the drive motor, a steering motor for auxiliary steering, a second control or regulating device for the steering motor and a sensor device which produces a set signal for the second control or regulating device according to the extent of a steering movement of the handle lever are provided, the handle lever rod acting on the steering base via two horizontally spaced pivot points and at least one sensor being associated to each pivot point to measure the force between the handle lever rod and the steering base. The second control or regulating device produces a control signal for the steering motor from the signals of the two sensors.
