A sensor unit, in particular a sensor unit in or on a vehicle, for capacitively ascertaining the distance between the sensor device and an object, having an electrode for forming a capacitive system with the object and an apparatus for creating a signal proportional to the capacitance of the capacitive system. The sensor unit has a reference electrode for forming a capacitive reference system with the object, an additional apparatus for creating a reference signal proportional to the capacitance of the capacitive reference system, and an analyzer device for ascertaining the distance by forming a ratio of the signal and the reference signal, the reference electrodes having an electrode shape, which is different from the electrode shape of the electrode.

Sensor device for capacitively ascertaining distance

A measuring station for measuring vehicles has at least one laser source, which emits laser radiation () during operation, and a safety system, which includes at least one sensor, which is set up to detect objects. The safety system is configured in such a way that it switches off the laser source when at least one sensor detects an object which approaches a region in which the laser radiation emitted by the laser source has a particularly high intensity.

Measuring station for measuring vehicles

A method for the detection of surroundings is performed using a source which emits pulsed signals. Signals backscattered from an object are detected by a sensor. When performing the method, a presence of the object is detected during coarse sampling. To determine a variable related to the detected object, operating parameters of the source are set for fine sampling.
