An open roof assembly for use in a vehicle roof of a vehicle comprises a moveably arranged closure member for selectively covering or at least partially exposing an opening in the vehicle roof, an electric motor operatively coupled to the closure member through a mechanical drive assembly for moving the closure member, an electric driving unit for providing a supply signal to the electric motor and a control unit operatively coupled to the electric driving unit for controlling operation of the electric motor. The electric driving unit comprises four switching devices in a bridged configuration and the control unit is configured to control a motion of the closure member by controlling operation of the switching devices, and to incur a safety stop during a motion of the closure member by an immediate reversal of a polarity of the supply signal.
