Abstract

The invention relates to the field of road traffic safety, and discloses an intelligent sensing early warning method and system based on a vehicle state and a driving environment. The method comprisesthe steps of obtaining the state and driving environment parameters of a vehicle, carrying out data preprocessing on the state of the vehicle and the driving environment parameters, carrying out safety characteristic index quantification, analyzing the scalar indexes by using a method of combining single factor analysis and principal component analysis, and establishing a safety prediction modelbased on the vehicle state and the driving environment, and establishing an early warning strategy according to the safety prediction model based on the vehicle state and the driving environment. Thevehicle state information and the driving environment information are fused; a safety prediction model based on the vehicle state and the driving environment is constructed; the intelligent sensing early warning system based on the vehicle state and the driving environment is provided based on the safety prediction model, effective identification and pre-judgment of the vehicle operation safety are achieved, the early warning accuracy is high, the road traffic accident rate is reduced, and the road traffic safety is guaranteed.

Description

technical field [0001] The present invention relates to the field of highway traffic safety, in particular to an intelligent perception early warning method and system based on vehicle state and driving environment. Background technique [0002] With the continuous development of technologies such as artificial intelligence, big data, cloud platform, and 5G, road traffic is gradually becoming intelligent, and a large number of intelligent auxiliary facilities have been put into use, effectively improving the safety level of road traffic. With the mileage of the road network and the rapid growth of car ownership, a large number of traffic accidents are still occurring, especially on road accident-prone sections. At present, for accident-prone road sections, the safety of road vehicles is mainly guaranteed by adding auxiliary facilities such as warning signs, safety guidance facilities, video surveillance equipment, and speed measurement. Although it can reduce the occurrence ...
