<p><P>PROBLEM TO BE SOLVED: To provide a car-to-car communication device for exchanging information between vehicles with no long time required for specifying a communication partner, and with the effect of elimination of interference of radar waves. <P>SOLUTION: The device comprises a timing matching means which allows a radar device 12 of an own vehicle 10 to transmit radar waves at a timing matched with a satellite time information received from the satellite of a positioning system; a detecting means for detecting positional information of other vehicle from the beat between the radar waves transmitted from the radar device 22 of other vehicle 20 at the timing matched with the satellite time information, and the radar waves transmitted from the laser device of the own vehicle at the timing matched with the satellite time information; a transmitting means for transmitting radar waves multiplexed with communication information if other vehicle is present within a specified range from the own vehicle, based on the positional information for the other vehicle; and a receiving means for splitting and extracting a communication information from the radar waves received from the other vehicle. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
