Brief component description

The data of the ride height sensors on front axle and rear axle are evaluated through the BDC and made available for other vehicle electrical system participants. For example, the "automatic headlight beam throw adjustment" function also accesses this data. It adjusts the headlight beam throw so that the oncoming traffic is not dazzled.

The ride height sensor is a non-contact sensor. The ride height sensor converts the distance covered proportionally through an angle of rotation into an analogue voltage signal. The sensor can be rotated by 360°. The measuring range is 70° (depending on the installation location, sawtooth-shaped characteristic curve). The signals are output as analogue electrical voltages.
