Intelligent vehicle target tracking system and method employing DSRC and vehicle sensor in combination

Abstract

The invention discloses an intelligent vehicle target tracking system and method employing DSRC (Dedicated Short Range Communications) and vehicle sensor in combination and relates to the technical field of intelligent vehicle target tracking and vehicle communication. The system includes a vehicle-sensor-based target detection module, a DSRC communication module, a target tracking module and a vehicle locating module. The target detection module detects location information of vehicles and pedestrians in the surrounding of a main vehicle through the vehicle sensor. The DSRC communication module receives target vehicle self movement state and identify information delivered by target vehicles having a DSRC-based information issuing function in a communication range. The target tracking module performs data association according to detected target observation data and modifies an association result according to the state and the identity information of the target vehicles, then performs tracking filtering on the modified association result and obtains more accurate movement states of the targets in the surrounding. The vehicle positioning locating module is used for obtaining the movement state of the main vehicle for delivering. The system and method provided by the invention improves intelligent vehicle target tracking precision.

Description

technical field [0001] The invention belongs to computer and automation technology, especially the field of intelligent vehicle target tracking technology, and specifically relates to a multi-target tracking method using DSRC (Dedicated Short Range Communications, dedicated short-range wireless communication) communication technology combined with vehicle sensor observation. Background technique [0002] The target tracking system is an important part of intelligent vehicles. In order to realize collision warning and vehicle automatic driving control, it is necessary to accurately detect and estimate various targets in the surrounding environment of intelligent vehicles, including accurate position and motion state information of vehicles and pedestrians. [0003] Chinese Patent Application: Vehicle Control Equipment, Target Guidance Vehicle Designation Equipment, and Vehicle Control Method (Application No.: 201180017118.X) discloses a vehicle communication unit and a radar d...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the current intelligent vehicle target tracking system in the scene where the target vehicle publishes its own information within the communication range of the main vehicle, the traditional target tracking method fails to make full use of the identity information and status information released by the target vehicle, resulting in data loss during the target tracking process. The correlation results are not accurate enough and the tracking accuracy is not high. The present invention proposes an intelligent vehicle target tracking system and method using DSRC and vehicle sensor fusion
