IPC: G08B25/00
Filed: 2000-06-12
Abstract: PROBLEM TO BE SOLVED: To give emergency information even in an area outside of a communication circle where the radio base station of portable telephone does not exist in the neighborhood. SOLUTION: Pieces of on vehicle emergency informing equipment can communicate with each other by storing and repeating. When an emergency information communication means 1 cannot communicate with a radio base station, a repeating request signal for requesting repeating of emergency information is issued to another vehicle.
