Abstract
An object of the present invention is to provide a method capable of calibrating a sensor function required in a safety design of a radar safety sensor in real time. A calibration station () is provided on a traveling route of an unmanned vehicle () on which a safety sensor () for detecting an obstacle () ahead is mounted, and a standard reflection is provided at a position of a maximum measurement distance (L) of the safety sensor () at the calibration station (). Prior to normal traveling of the unmanned trolley, the unmanned trolleyis moved to the calibration stationin advance, and the reference value obtained by measuring the standard reflectorwith the safety sensoris taught, During normal operation of the unmanned trolley, every time the unmanned trolleyreaches the calibration station, the measured value obtained by measuring the standard reflectorby the safety sensoris compared with a reference value. Calibrate the sensor function of.
