PROBLEM TO BE SOLVED: To confirm that one automobile recognizes that the other automobile is out of a route by making a second automobile carry out and transmit a re-routing calculation to a first automobile when the second automobile is detected to be out of the route, and making the first automobile transmit to the second automobile that it receives the calculation. SOLUTION: When one's vehicle CM automatically sets an optimum route and starts to a destination, a re-route is displayed at a display device of the vehicle CM on the basis of a re-route information received from an accompanying vehicle CP. If the accompanying vehicle CP is out of the route at an off route point Por on the optimum route to the destination, a CPU of the accompanying vehicle CP immediately calculates a re-route. After the accompanying vehicle CP calculates the re-route, information of the re-route is automatically transmitted from the vehicle CP to the vehicle CM. When receiving the information of the re-route, the vehicle CM displays the re-route at the display device and transmits a confirmation signal indicating the reception of the re-route information to the transmitting vehicle CP. |
