Cooperative vehicle-road early-warning device based on road junction vehicle collision avoidance and operating method of device

Abstract

The invention discloses a cooperative vehicle-road early-warning device based on road junction vehicle collision avoidance and an operating method of the device. The device comprises a base station and an early-warning system, wherein the base station is built at a road junction, and the early-warning system is mounted in a vehicle. By information interaction of the road junction base station and the vehicle, a collision risk is transmitted to the vehicle through wireless signals, the vehicle reminds a driver of danger conditions through a visual display device, and the early-warning system actively reduces speed to avoid collision if sensing that the driver continuously reminded does not perform operation action. The device can effectively avoid collision for an automobile suddenly appearing in front of the vehicle at the road junction. The collision risk of the vehicle in a current risk field is identified by a central processing unit A of the base station for the road junction with a complicated road condition, a large amount of calculation is performed at the base station, requirements for the vehicle are low, an expensive sensor mounted in the vehicle is omitted, and economic benefits are high.

Description

technical field [0001] The invention relates to the fields of traffic safety and vehicle-road coordination, in particular to a vehicle-road coordination early warning device and a working method thereof. Background technique [0002] With the continuous growth of my country's automobile production and sales, the traffic flow on the road is constantly increasing, and with the construction of urban-rural integration, the urban-rural road network is expanding rapidly. While enjoying the convenience of transportation, it is bound to increase the complexity of road traffic. The vicious traffic accidents that above-mentioned problem brings occur frequently. It is particularly important to design a vehicle active safety device for intersections. At present, in terms of active safety of automobiles, data is collected mainly through sensors or image processing technology, combined with the operating parameters of the vehicle to determine whether there is a risk of collision, and then...

AI Technical Summary

Problems solved by technology

This method cannot effectively avoid the collision of the car that suddenly appears in front of the car at the intersection, and it requires the vehicle to be equipped with multiple expensive sensors such as ultrasonic waves, which is costly and insufficient in implementability
