Abstract
A method and an apparatus for the transference of traffic information among vehicles and for assisting navigating the vehicles. The traffic information of the vehicles, such as the speed and the route and direction, is remotely transmitted to each other during passing, via communication devices mounted on each of the vehicles. The apparatus comprises sensors to detect the direction and the displacement of the vehicle; a microcomputer to recognize the position of the vehicle by referring the detected direction and displacement to a digitized map; a receiver to receive the passing vehicle's traffic information to be processed by the microcomputer; a transmitter to transmit the traffic information to the passing vehicle; and a navigation unit in the microcomputer to generate navigation information and indicate the traffic information of vehicles ahead is transmitted to a receiving vehicle in an indirect manner via a passing vehicle.
