Abstract
The invention relates to a device for determining the height of the chassis (2) of a vehicle using at least one displacement sensor (3) which is mounted between the chassis (2) and a vehicle suspension system (4) and which is designed to detect a relative vertical movement between the chassis (2) and the suspension system (4). According to the invention, the device consists of a contactless linear magnetic position sensor having two different parts (31, 32), namely: one part comprising (i) a magnetic core which is magnetised by at least one field coil which is supplied with alternating current and (ii) at least one detection coil which is coupled to the magnetic core; and another part which is fixed to the suspension system (4) and which comprises a magnet that creates a virtual gap in the magnetic core, the position of said magnet affecting the magnetic flux leakage and, consequently, the voltage delivered by the detection coil.
