Abstract

A moving body detection system for detecting moving bodies by transmitting and receiving signals between the moving bodies. Each moving body transmits an ID code capable of identifying the moving body itself. A detection side moving body receives the ID code signal based on changes in driving conditions, discriminates the received ID signal, and transmits a detection signal with the ID code and the ID code of the detection side moving body itself added thereto. A non-detection side moving body receives the detection signal, and transmits a response signal with its own ID code and the ID code of the detection side moving body added if the ID code added to the detection signal is the same as its own ID code. Furthermore, the detection side moving body receives the response signal and measures the distance to the non-detection side moving body having the same ID code as the response signal.
