Level setting for distance measurement devices in motor vehicles

摘要

The method involves directing at least one electromagnetic pulse transition time sensor channel at the road in front of the vehicle (101) and evaluating the pulse shape and/or the distance of the echo in front of the vehicle to set the pitch angle of the sensor system. By applying the sensor system at a large vertical distance from the road, the pulse transition time sensor channel directed towards the road can be simultaneously used for distance measurement of very low vehicles (301) which are close to the vehicle.
