(FR2752400-A1)      The control system has a control device (2) coupled via control lines to motor drivers for each of the vehicle door locks (4). The control device is supplied from the vehicle battery (10), with a stand-by energy supply (11) for emergency operation coupled to emergency operating drives for decentralised operation of individual door locks. The stand-by energy source is connected between the battery and the motor drivers for the door locks and provides a reduced voltage output relative to the battery voltage.    ADVANTAGE -   Ensures emergency operation of door locks, and as required operation of other vehicle components, such as vehicle window drives, anti-theft device etc.    (JP10153027-A)      The control system has a control device (2) coupled via control lines to motor drivers for each of the vehicle door locks (4).
