Abstract

The invention discloses a vehicle-road cooperative early warning device based on vehicle collision avoidance at an intersection and a working method thereof. The device includes a base station and an early warning system, the base station is established at the intersection, and the early warning system is installed in the vehicle. The invention interacts with the vehicle's early warning system information through the intersection base station and transmits the collision risk to the vehicle by wireless signals, and the vehicle reminds the driver of the dangerous situation through the visual display device. Actively slow down to avoid a collision. The present invention can effectively avoid collision for the vehicle suddenly appearing in front of the vehicle at the intersection. In the present invention, for intersections with complex road conditions, the central processing unit A of the base station performs collision risk identification for vehicles in the current risk field, a large number of calculations are performed at the base station, the requirements for vehicles are low, and expensive sensors do not need to be installed in the vehicle. high economic efficiency.

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 automobile production and sales in my country, the traffic flow on the road is 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. Vicious traffic accidents caused by the above problems are frequent. It is particularly important to design a vehicle active safety device for the intersection. At present, in terms of active safety of automobiles, data is mainly collected 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 sound reminders or ac...
