摘要

Drive control device for a vehicle, in particular for a wheelchair. The vehicle has two drive wheels which can each be driven by an electric motor, and at least one swivellable running wheel which can assume an angular position with respect to a reference axis of the vehicle. The drive control device comprises an operating unit and a control unit. The operating unit feeds two operating signals representing the desired speed and direction of the vehicle to the control unit. The control unit outputs an output signal to each electric motor. The drive control device furthermore comprises a sensor which feeds a wheel-position signal representing the angular position of a swivellable running wheel to the control unit. The control unit has a first control circuit which determines the output signals as a function of the first operating signal and the second operating signal and the wheel-position signal in such a way that the actual direction of the vehicle is adjusted to the desired direction. The drive control device furthermore comprises an electrical wheel steering device which can be linked to a swivellable running wheel of the vehicle.
