Device for determining the position of a first vehicle component relative to a second one, in particular for determining the pitch of a vehicle, and vehicle fitted with such a device

摘要

An inductive measuring system (100) contactlessly determines the space between two motor vehicle parts. A free-running oscillator (10) has an amplifier (15) for reducing the damping of its oscillation circuit (30) by negative feedback. The oscillator has a feedback branch (21) for exciting the oscillation circuit connected between the output (18) and input (16) of the amplifier. The feedback branch includes a device (19,20) for generating a square-wave voltage signal (VRE) from an alternating voltage (VSIN). An independent claim is included for a vehicle with an apparatus for controlling the headlight range based on the pitch of the vehicle.
