Conventional vehicles have a multiplicity of safety functions which are dependent on ambient data of the vehicle. This has the effect of sensing, for example, bends, other vehicles etc. and correspondingly reacting. This usually requires a multiplicity of sensors, and depending on the sensor, also emitters for outputting radiation. Usually an ultrasonic system or a radar system is used for distance measurement. An ultrasonic system is used, for example, for a parking aid in which only one distance measurement takes place. Radar systems serve as distance control systems but also as a parking aid. Said systems can be provided as distance control systems for autonomous or partially autonomous driving. Such systems usually require additional installation space and give rise to additional costs.
