Abstract (en)

[origin: FR2824351A1] The door locking system includes three relays.. The third relay (C3) is switched into an actuating position to interrupt the supply to the second (M2) of the two motors. Then the first and third relays (C1,C3) are switched, at the same time, into a release state so as to return all three relays to a rest state. Control method for a vehicle door lock including a first electric motor (M1) electrically fed via a first relay (C1), with a second motor (M2) fed via the first relay and a third relay (C3). Each relay can be switched between a release state in which it is connected to the vehicles negative supply terminal (-) and an actuated state in which it is connected to the vehicles positive supply terminal (+). From the release state of the three relays, the first (C1) and second (C2) relays are switched at the same time into an actuated state for feeding the second motor (M2). Followed by switching the second relay (C2) into a release state for supply to the first motor (M1) whilst maintaining the first relay in its actuated state and the third relay (C3) in its release state

Abstract (fr)

Le procédé de commande pour une serrure d'ouvrant de véhicule automobile comprenant un premier moteur électrique (M1) alimenté électriquement par l'intermédiaire d'un premier relais (C1) et d'un deuxième relais (C2), et un second moteur électrique (M2) alimenté par l'intermédiaire dudit premier relais (C1) et d'un troisième relais (C3), chaque relais pouvant être commuté entre un état relâché et un état actionné, consiste, à partir d'un état relâché des trois relais, à commuter le premier relais (C1) et le deuxième relais (C2) en même temps dans un état actionné pour alimenter le second moteur (M2), puis ensuite, à commuter le deuxième relais (C2) dans un état relâché pour alimenter le premier moteur (M1). Les variations du courant sont ainsi réduites, ce qui permet d'utiliser un premier relais de plus petites dimensions. <IMAGE>
