A Safe Driving Support System for Motor Vehicles with DSRC

In this paper, a safe driving support system for motor vehicles is disclosed. The system is designed to prevent traffic accidents via inter-vehicle communication even in the case where a driver cannot obtain sufficient information of a region, such as curved roads, crossroads, and the like, using only auditory and sight senses. The system is operated as follows via an antenna and communication module mounted on a vehicle. When receiving information of an opponent vehicle on the road via inter-vehicle communication, the system compares conditions of a host vehicle with those of the opponent vehicle and determines a proper service for the host vehicle. Then, a warning for a driver of the host vehicle was generated as a front-vehicle warning, rear-vehicle warning, side-vehicle warning, host-vehicle warning, etc. in accordance with the determined service. In the experiment for checking the operation of the system, the prototype vehicle sent and received vehicle information, such as vehicle speeds, vehicle positions, parking and stopping of a vehicle, driving conditions, driving directions, and the like, and provided the information to the driver of the host vehicle. Further, the system calculated a vehicle-to-vehicle distance, and processed information of curved roads and crossroads and alarm generation in accordance with a degree of danger through the vehicle terminal.
