METHOD FOR DETECTING THE INTENT TO LOCK OR UNLOCK A VEHICLE DOOR AND ASSOCIATED DETECTION DEVICE

摘要

The subject of the present invention is a device for detecting (D) an intention to lock or unlock a door of a motor vehicle, said device (D) comprising at least a first inductive sensor (A1), comprising a first target ( 20), an oscillating circuit (M1) comprising a coil (B), means for measuring a resonant frequency of said circuit (M2), and a printed circuit, (10), said device (D) being characterized in what it comprises a second inductive sensor (A2) comprising: • a second target (30) in the form of a loop, such that a first end (E1) of the loop is connected to a fixed potential, and a second end ( E2) of the loop connected to switching means (S1) having two states: • in a first state (P1), the second end (E2) of the loop is connected to said fixed potential, • in a second state (P2) , the second end (E2) of the loop is connected to a floating potential ant, • control means (M3) of the switching means (S1), • the coil (B) of the first inductive sensor (A1) being common to the second inductive sensor (A2).
