PROBLEM TO BE SOLVED: To improve the communication efficiency of position information due to inter-vehicle multi-hop communication by increasing the number of pieces of position information of a mobile object which can be transmitted in one communication frame.SOLUTION: An information processing part 150 acquires position information of an own device transmitted from a position detection part 120, and other device transmission position information including position information (transmission device position information) of other communication device transmitted from the other communication device through a radio transmission/reception part 110 among communication devices (100, 200, ...) for performing short-range radio communication of a prescribed standard. Subsequently, the information processing part 150 generates compound position information including the position information of the own device and relative position information of the other communication device to the own device on the basis of the acquired own device position information and other device transmission position information. Then, the information processing part 150 transmits the generated compound position information to the outside by using the radio transmission/reception part 110.SELECTED DRAWING: Figure 1 |
