A method for determining the occupation state of a parking space, including the steps of: providing a first detection unit equipped with a frequency modulated continuous wave radar; preparing a decision unit and a second detection unit; transmitting via the radar a communication signal modulated on the basis of a first code, alternatively indicating the parking space or a vehicle; receiving the communication signal with the second detection unit; demodulating the first code with the second detection unit; transmitting the first code to the decision unit via the second detection unit; and determining, with the decision unit, the occupation state on the basis of the first code and the second code, alternatively indicating either a vehicle or the parking space.

Method and system for determining the occupation state of a parking space

A proximity sensor for a parking area designed to detect the presence of an obstacle constituted by a parked vehicle, comprises a transmitting radar, designed to send electromagnetic pulses towards the obstacle, a receiving radar, designed to receive the pulses reflected by the obstacle, and a processing circuit, designed to compare samples detected in a certain condition of absence of an obstacle in a calibration step with those detected in a condition of detection of an obstacle to determine the presence/absence of the obstacle.
