Abstract
Disclosed is a device for detecting intention to lock or unlock a door of a motor vehicle, the device including at least a first inductive sensor, including a first target, an oscillating circuit including a coil, a unit measuring a resonant frequency of the circuit, and a printed circuit. The device includes a second inductive sensor including: a second target in the form of a loop, such that a first end of the loop is connected to a fixed potential, and a second end of the loop is connected to a switch having two states, in a first state, the second end of the loop is connected to the fixed potential, in a second state, the second end of the loop is connected to a floating potential; and a controller for the switch. The coil of the first inductive sensor is common to the second inductive sensor.
