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.
