The invention discloses a vehicle threat assessment system based on DSRC and Telematics, and vehicle-mounted equipment consists of a data collection and communication module and a threat assessment module. Road side equipment consists of a DSRC communication module and a vehicle-tracking module. The data collection and communication module of the vehicle-mounted equipment collects the state and position information of a vehicle, broadcasts the state and information of the vehicle through DSRC, and receives the state and position information, transmitted by the road side equipment, of a surrounding vehicle through DSRC, and obtains the environmental information through Telematics service. The threat assessment module achieves the correction of threat assessment results, and obtains a more accurate threat index of the surrounding vehicle to the vehicle, wherein the threat index serves as the basis for subsequent warning/control. The DSRC communication module of the road side equipment receives the states and position information of all vehicles, and broadcasts the information processed by the tracking module. The vehicle-tracking module achieves the tracking filtering of the states and position information, which are received by the DSRC communication module, of all vehicles, so as to improve the precision and reliability.
