MOBILE COMMUNICATION EQUIPMENT

PROBLEM TO BE SOLVED: To give other traveling objects necessary information regarding one traveling object by detecting abnormality of a mutual communication among the traveling objects and repeating a specific information signal. SOLUTION: A controller reads data contents of an information signal from another vehicle nearby an own-vehicle which is received by a radio equipment, decides whether or not there are multiple vehicles traveling toward the same intersection forward, and calculates time differences in the time of arrival at the intersections among the vehicles (S1 to 3). When there are vehicles having the time difference in arrival time less than the specific time, it is decided whether or not those vehicles are sending danger alarm ON to each other (S4, 5). When the danger alarm ON is not indicated in the information signal from one or both of the vehicles, it is considered that a communication between those vehicles is not established and the information signal indicating the presence of approaching danger object vehicles is generated and sent to the radio communication equipment for the vehicle which does not indicate the danger alarm ON (S6).
