Operation risk prevention method of vehicle navigation system using global positioning system

摘要

The present invention relates to a method for preventing driving hazards of a vehicle navigation system using a global positioning system (GPS). In particular, a global positioning system is added to a charrang navigation system to detect unexpected problems on a national highway or a high-speed national highway. The present invention relates to a method for preventing driving hazards of a vehicle navigation system using a global positioning system for providing a better driving information to a driver by notifying a driver of a driving position or notifying a surrounding position of a driving position and preventing a danger.;According to an exemplary embodiment of the present invention, a method for preventing a driving hazard of a vehicle navigation system using a global positioning system sets an initial carrier on which data is to be carried, and the received signal is initially examined for a carrier carrying data allocated within a bandwidth provided in the system. And determining whether the carriers are duplicated in transmission and reception, and if the transmission and reception carriers are different carriers, extracting and outputting data on the receiving carrier while sequentially increasing the carriers one by one. If the received carrier is the same as the transmission carrier, the carrier includes changing the redundant carrier and loading the data of the vehicle on the changed carrier and transmitting the same to another vehicle.
