Embodiment Construction

[0010] Combine below figure 1 , the present invention is described in further detail.

[0011] refer to figure 1 , an automatic car following system, including a processing module 10 and a control module 20, the processing module 10 includes a decision controller 11, an image acquisition unit 12 and a radar acquisition unit 13, and the image acquisition unit 12 is used to acquire the front of the vehicle The video or image information is processed to obtain the relative position information of the vehicle in the lane. The radar acquisition unit 13 is used to detect the distance, orientation and speed information of the obstacle in front of the vehicle. The decision controller 11 receives the image acquisition unit 12 and the radar acquisition unit. The information output by 13 is processed and output vehicle speed, angle and angular velocity control commands to the control module 20, and the control module 20 controls the vehicle speed and direction according to the control c...

Abstract

The invention relates to the field of smart cars, in particular to an automatic car tracking system, comprising a processing module and a control module. The processing module comprises a decision controller, an image acquisition unit and a radar acquisition unit. The image acquisition unit is used for obtaining video or image information in front of a car and performing processing to obtain the relative position information of the car on the lane, the radar acquisition unit is used for detecting distance, position and speed information of an obstacle in front of the car, the decision controller is used for outputting car speed, angle and angular velocity control commands to the control module after receiving and processing the information, and the control module is used for controlling the car speed and direction according to the control commands. The invention also discloses a control method of the system. The image and the radar technology are combined, the car is detected and tracked more accurately, the safety issue under multiple weather conditions is better solved, traffic accidents caused by urban road congestion are reduced, safety is improved and the mental pressure of drivers is alleviated.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to an automatic car-following system and a control method thereof. Background technique [0002] With the development of our country's economy, the number of cars has increased rapidly, which has made urban traffic congestion more and more serious, and also brought huge mental pressure to drivers. At present, there is also car following in the market that uses a single sensor to obtain the vehicle in front and the surrounding environment for assistance. In a sense, it does not reduce the driver's fatigue. In addition, the reliability and safety of autonomous car following are not very good. guarantee. Contents of the invention [0003] The primary purpose of the present invention is to provide a reliable automatic car-following system to improve the real-time performance, safety and reliability of the automatic car-following system. [0004] In order to achieve the above obje...
