A drive unit for a window wiper system having an electronically commutated drive motor, which has a rotor and phase conductors for providing a stator magnetic field; a reversing transmission, which controls one or more wiper arms of a wiper unit in a pivoting motion with alternating direction; a power unit, which provides phase voltages to the drive motor based on control signals and which has a device for measuring phase currents through the phase conductors; and a control unit, which determines a rotor position of the rotor of the drive motor based on the phase currents without using any sensors to generate the control signals based on the rotor position to provide a drive torque and to control rotational speed based on a specified operating function.
