The data control system comprises a data server and a data displayer, the industrial personal computer is communicated with the data server through a public network data converter, and the data server is connected with the data displayer. According to the system, a targetcar can be monitored. The invention further discloses a car trajectory tracking method. According to the tracking method, the moving track of the target car can be accurately tracked and positioned,and high innovativeness is achieved.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to a vehicle target trajectory tracking system and a vehicle trajectory tracking method. Background technique [0002] With the continuous development of the national economy and the continuous increase in the number of cars, the popularization of motor vehicles not only brings convenience to people's travel, but also causes serious problems such as traffic congestion, traffic accidents and environmental pollution. Intelligent traffic control is an effective means to alleviate traffic problems, and accurate and real-time perception of road traffic status is the premise of formulating reliable traffic control strategies. Among them, the vehicle's driving trajectory is an important manifestation of the driver's behavior. It can not only detect some uncivilized driving behaviors such as continuous lane changes, ghost walks, and snakes that appear in the driver's driving process, but ...
