UNE CENTRALE DE VERROUILLAGE, NOTAMMENT DES PORTIERES ET AUTRES FERMETURES DE VEHICULES AUTOMOBILES, COMPORTE PLUSIEURS SYSTEMES MOTEURS ELECTRIQUES 1 POUR L'ACTIONNEMENT DES VERROUS ET UN CIRCUIT COMMANDE PAR UN COMMUTATEUR 5, QUI ENVOIE UNE IMPULSION UNIQUE AUX SYSTEMES MOTEURS POUR LES METTRE EN MARCHE DANS UN SENS DE VERROUILLAGE OU DE DEVERROUILLAGE, SUIVANT SA POSITION, CE CIRCUIT PRODUISANT CES IMPUSLIONS EN FONCTION DU FLUX DE COURANT DANS UN CONDENSATEUR. LE CONDENSATEUR 3 EST, DANS UNE PREMIERE POSITION DU COMMUTATEUR 5, RELIE A UN CIRCUIT DE CHARGE, DANS LEQUEL LE COURANT DE CHARGE DETERMINE L'IMPULSION MOTRICE POUR UN PREMIER SENS DE FONCTIONNEMENT DES SYSTEMES MOTEURS ET, DANS UNE SECONDE POSITION, IL EST RELIE A UN CIRCUIT DE DECHARGE, DANS LEQUEL LE COURANT DE DECHARGE DETERMINE L'IMPULSION MOTRICE DANS LE SECOND SENS DE FONCTIONNEMENT DES SYSTEMES MOTEURS A central locking system particularly suitable for use in a motor vehicle to lock or open, at one time, all the vehicle doors from any one of a number of locations, includes at least one lock bolt mechanism which provides movement in a selected one of a locking and a release direction to locking elements at the vehicle doors. At least one control switch which may be located at the door on the driver's side of the vehicle is selectively actuable to one of first and second switch positions, and is arranged together with a pulse drive circuit including a capacitor to provide a first drive pulse to the lock bolt mechanism when the control switch is in the first switch position. The first drive pulse causes the lock bolt mechanism to move the locking elements at the vehicle doors in one of the locking and release directions, and is produced by the capacitor in response to a charging current supplied to the capacitor by a charging current circuit. When the control switch is in the second position, a discharging current circuit is coupled to the capacitor and directs a discharging current from the capacitor. This allows the capacitor to provide a second drive pulse to the lock bolt mechanism, and causes the mechanism to move the locking elements at the vehicle doors in the other one of the locking and release directions.
