Driving environment safety evaluation method and device

Abstract

The invention discloses a driving environment safety evaluation method, and the method comprises the steps: dividing a target object in a current driving environment into target object sets, and determining spatial vectors corresponding to the target object sets which do not comprise to-be-evaluated target objects, and spatial vectors of the target object set including the target objects to be evaluated corresponding to various potential driving tasks, and based on spatial vectors, corresponding to various potential driving tasks, of a target set including to-be-evaluated targets and spatial vectors, not including the to-be-evaluated targets, of the target set, determining safety coefficients corresponding to various potential driving tasks, thereby determining a safe driving task suitable for the to-be-evaluated target object. According to the method, the driving environment safety of the to-be-assessed target object can be comprehensively assessed according to each target object in the current driving environment, and the safety corresponding to various potential driving tasks is predicted, so that intelligent driving is realized, the driving risk is avoided, and a basic guarantee is provided for quickly responding to the risk.

Description

Technical field[0001]The present application relates to the field of smart driving technology, and more particularly to a driving environment safety assessment method and apparatus.Background technique[0002]Road transportation systems are a dynamic system composed of many factors such as people, cars, roads and environments. In this system, any factors are unreliable, unbalanced, and unstable may lead to various conflict conditions, such as traffic accidents. The occurrence of the driving environment is accurately evaluated for driving environment safety, and the occurrence of traffic accidents can be effectively avoided to some extent.[0003]The current driving environment safety assessment system evaluates the safety of the vehicle, typically based on the relative movement between the vehicle and the target, determining the safety assessment result of the driving environment; specifically, if the predicted vehicle and the target The collision time is less than the preset threshold,...

Problems solved by technology

[0004] However, the above-mentioned evaluation method can only be evaluated based on the current relative driving state of the vehicle and the target object. When a situation of low safety is determined, it is usually difficult for the vehicle to respond in time, and the vehicle is prone to lag behind in avoiding danger; in addition, only Based on the current relative driving state of the vehicle and the target object, the safety evaluation results obtained are relatively one-sided and the accuracy is usually low
