Abstract

Un module de verrouillage d'un véhicule à moteur, qui peut se présenter sous forme d'un module de verrouillage de la porte et/ou de l'allumage, comprend une clé (26) et un verrou (34) monté sur le véhicule à moteur. Un émetteur portatif (24) relié à la clé (26) émet lorsque l'on actionne un déclencheur (32) un signal codé qui sert à actionnner à distance le verrou de la porte du véhicule à moteur. Lorsque l'on insère la clé (20, 26) dans le verrou (34), l'émetteur reçoit une tension tirée du réseau de bord du véhicule à moteur afin de recharger son dispositif d'alimentation en courant (44).
