Embodiment

[0047] A vehicle anti-collision warning system based on vehicle-road coordination, the system includes an on-board device OBU, a roadside device RSU installed near the road, a control module, a communication module, and a roadside prompt device;

[0048] The vehicle-mounted equipment consists of a vehicle-mounted GPS module and an acceleration sensor, which is used to obtain vehicle driving information including speed, direction, position, acceleration and other data. After the vehicle obtains relevant motion information, it transmits and aggregates the data to the control module through the communication module.

[0049] Roadside equipment collects vehicle position and environmental information within the relevant area, mainly moving vehicles and their positions in the traffic environment, and uses spatial alignment to remove redundancy from the detection information of joint video detection equipment and lidar detection equipment To improve the detection accuracy, the releva...

Abstract

The invention discloses a vehicle anti-collision early warning system and method based on vehicle-road cooperation. The early warning system comprises a vehicle device, a roadside device, a control module, a communication module and a roadside prompting device; the vehicle device and the roadside device are subjected to data exchange through the communication module, the various collected data are converged to the control module through the established data channel to perform collision risk assessment, and early warning information or control instructions formed after risk assessment information are issued to a vehicle terminal or the roadside prompting device to prompt the vehicle to take corresponding measures to avoid vehicle collision. According to the invention, the accurate collision risk value of the vehicle can be obtained by means of a vehicle-road cooperation technology and a collision early warning model, the vehicle device can remind the vehicle to take corresponding anti-collision measures through voice and images after receiving early warning information, and the roadside prompting device performs collision risk prompting through lamplight or display device.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a vehicle anti-collision warning system and method based on vehicle-road coordination. Background technique [0002] With the rapid development of high-tech technologies such as communication technology, computer technology, information technology, and the Internet of Things, people's travel experience is also undergoing earth-shaking changes. Collaborative research, vehicle-road coordination technology is mainly to realize real-time information interaction between vehicles and vehicles, and carry out active safety control based on the collection and fusion of full-time dynamic traffic information, fully realize the effective coordination of people, vehicles and roads, ensure traffic safety, and improve traffic safety. traffic efficiency. [0003] At present, scholars and institutions at home and abroad have carried out relevant research on anti-collision, and...
