Abstract:
A method for guiding a vehicle in which a transmission signal of a position transmitting device installed at key points on a roadside is received by a position receiving device mounted in the vehicle, comprising the steps of:receiving traffic information for service to a vehicle moving on a road from a traffic information network; receiving position information on the road and the traffic information received from an interface unit as code values and storing the same; modulating the position information and the traffic information as coded and stored in a recording unit, and wirelessly transmitting the same to each vehicle moving in the vicinity of the road; coding the position information on the road and the traffic information obtained by the interface unit, providing it to a recording unit, and controlling the transmitting operation of a first communication module and the receiving operation of the traffic information; receiving the transmission signal as modulated by the position transmitting device, classifying the information and the intensity of the signal from the received signal, and outputting the same; digitizing the intensity of the transmission signal as classified by the second communication module; measuring a travel distance of the vehicle and generating pulses in proportion to the measured travel distance; detecting the determined current position of the vehicle on the basis of the information as classified by a second communication module, the digital value according to the intensity of the signal and the measure pulse, analyzing the data to output a corresponding position information, travel information and danger information, and periodically controlling the operation of the second communication module; and visually and acoustically guiding the position information, the travel information and the danger information obtained by a second microprocessor.
