A vehicle threat assessment system based on dsrc and telematics

Abstract

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.

Description

technical field [0001] The invention relates to communication and automatic control technology, mainly a vehicle threat assessment system based on DSRC (Dedicated Short Range Communications, dedicated short-range wireless communication) and Telematics (vehicle information service). Background technique [0002] The number of cars is increasing day by day, coupled with the complexity of road forms and surrounding environments, resulting in frequent vehicle traffic accidents. The current passive safety technology has been maturely used in different automobile manufacturers, and it has played a certain role in collision avoidance and mitigation when traffic accidents occur. However, due to the limitations of traditional passive safety, it is relatively difficult to further reduce the harm caused by collisions difficult. The active collision avoidance system can predict and evaluate possible accidents in advance through the perception of the surrounding environment, and take co...
