Method for controlling a close-range recognition system for vehicle and close-range recognition system

The method involves setting the distance measurement sensors to a first sensitivity equal to/greater than normal sensitivity, activating the sensors, disconnecting and setting to normal sensitivity any sensors receiving a reflected signal, assessing the received signal or only filtering it if it is a noise signal, not disconnecting sensors not receiving reflected signal and reactivating the disconnected sensors and evaluating the received signal. An Independent claim is also included for a short range detection system for vehicles.
