System for detection of the locking states of a motor vehicle

Abstract

A system for the detection of at least an open state of an opening of a motor vehicle and two other states of a lock of said opening, called a first state and a second state, includes two switching devices associated with the opening and the lock. One of the two switching devices includes a first contact breaker with a normally open or normally closed position detecting at least the open state of the opening. The two switching devices are connected to a ground cable. The first contact breaker detects the first state and is connected to a first information cable. The other of the two switching devices includes a second contact breaker with a position normally open or normally closed, detecting two states and is connected to a second information cable. Of the two states, one is common with the state detected by the first contact breaker. The first and second information cables are connected to analytical means.
