A drive unit for a steer-by-wire system for a vehicle having a motor for providing a drive power to a control rod of the wheel actuator. A sensor device determines the position of the control rod, wherein the sensor device has a first sensor unit and at least one second sensor unit. The first sensor unit is designed to detect an angle of a rotor shaft of the motor, and the second sensor unit is designed to detect an angle of an auxiliary shaft which is mechanically operatively connected to the rotor shaft. A transmission device provides the mechanical operative connection between the rotor shaft and the auxiliary shaft. A controller actuates the sensor device and/or determines the position of the control rod of the wheel actuator. The first sensor unit and second sensor unit use different measuring principles.
