<p>1. Arrangement for controlling a reversible electric drive for a pump of a pneumatic central locking system of a motor vehicle, comprising a pressure switch which, when a predetermined operating pressure is reached in the pneumatic system, initially stops the drive to the pump whereupon the drive is automatically activated in the opposite direction for venting the pneumatic system, characterized in that such a pressure switching device (pressure switch 10, control electronics 3) is in pressure-conducting connection with the pneumatic system, in that the pressure switching device switches off the reverse rotation of the drive (drive motor 5) only when a predetermined venting pressure has been reached.</p> |
