Vehicle early warning method, vehicle infrastructure cooperative system and storage medium

Abstract

The invention relates to the technical field of vehicle infrastructure cooperation, and discloses a vehicle early warning method, a vehicle infrastructure cooperative system and a storage medium. Thevehicle early warning method comprises the following steps that the early warning information of a local vehicle is acquired, and the early warning type of each early warning information is identified; according to the early warning type and a presupposed mapping relation, the early warning type scoring of the early warning information is obtained; according to the early warning type, a relative motion parameter between the local vehicle and a hazard source in the early warning information is acquired, and the early warning risk scoring of the early warning information is calculated accordingto the relative motion parameter; the number of vehicles in the surrounding area of the local vehicle is detected, and the vehicle density is calculated according to the number of vehicles; the earlywarning weight value of the early warning information is calculated according to the early warning type scoring, the early warning risk scoring and the vehicle density; and the early warning information, conforming to the early warning condition, of the early warning weight value is selected and output. According to the vehicle early warning method, the effective early warning can be accurately selected for alarming, the early warning accuracy is improved, and the interference of an early warning system to a driver or an advanced driving auxiliary system is reduced when multiple early warningsoccur simultaneously.

Description

technical field [0001] The invention relates to the technical field of vehicle-road coordination, in particular to a vehicle early warning method, a vehicle-road coordination system and a storage medium. Background technique [0002] Intelligent Vehicle Infrastructure Cooperative Systems (IVICS, Intelligent Vehicle Infrastructure Cooperative Systems) adopts advanced wireless communication and new-generation Internet technologies to comprehensively implement vehicle-vehicle and vehicle-road dynamic real-time information interaction, and collect and integrate dynamic traffic information in all time and space. Carry out active vehicle safety control and road collaborative management on the basis to fully realize the effective coordination of people, vehicles and roads, thus forming a safe, efficient and environmentally friendly road traffic system, which can help drivers make decisions and judgments faster, and is conducive to improving Driving safety, so the intelligent vehicl...

Problems solved by technology

However, in the process of implementing the present invention, the inventor found that the prior art has at least the following technical problems: in the case of multiple threats concurrently, the vehicle will obtain multiple early warning information. The early warning method of simply distinguishing the early warning level cannot accurately select the effective early warning information for notification, resulting in low accuracy of early warning, which will cause interference to the driver or Advanced Driving Assistant System (ADAS, Advanced Driving Assistant System)
