Abstract
In order to reliably communicate with a communication object even when a relative positional relationship with the communication object cannot be accurately recognized, an inter-mobile-body communication system includes: a control device which performs control of switching between a first mode of transmitting wide-area signal light, and a second mode of transmitting selective signal light toward a communication object in response to response signal light responding to the wide-area signal light transmitted in the first mode, and performs control of selectively receiving the response signal light from the communication object; and a light transmitting/receiving device which transmits the wide-area signal light in the first mode, transmits the selective signal light toward the communication object in the second mode, and selectively receives the response signal light from the communication object, according to control by the control device.
