<P>PROBLEM TO BE SOLVED: To provide an error detection means of a vehicle ID in the case of operation in radio communication between vehicles. <P>SOLUTION: In the case of a traveling order > the number of vehicles in line, a setting error of the vehicle ID is detected by operations of steps W2 to W7 (a step W15). In addition, when traveling orders of a compared ID and a comparison origin ID are the same, the setting error of the vehicle ID is detected by operations of steps W8 to W13 (a step W15). Furthermore, when the number of vehicles in line of the compared ID and the comparison origin ID are different, the setting error of the vehicle ID is detected by an operation of a step W14 (a step W15). In addition, when no data are present in a slot buffer of a counter value number, when the comparison origin ID is not set and group data of a reception ID is different from group data of the present vehicle, when the traveling orders of the compared ID and the comparison origin ID are different from each other and the number or vehicles of the compared ID and the comparison origin ID is coincident, a prescribed value is added to a slot counter in the step W5 by returning to the step W4 and loop is repeated until a beacon interval termination flag is raised in the step W3. <P>COPYRIGHT: (C)2004,JPO |
