Abstract

The present invention provides a system and method for estimating the road surface adhesion coefficient of the whole road network, which relate to the technical field of the Internet of Vehicles. coefficient and vehicle information, calculate the second road surface adhesion coefficient according to the vehicle information and the weather information collected in real time, and determine the current road surface adhesion coefficient and warning information according to the first road surface adhesion coefficient and the second road surface adhesion coefficient. The solution of the present invention realizes the real-time or pre-acquisition of road surface conditions during vehicle driving, and makes corresponding safe driving behaviors according to the current road surface adhesion coefficient and / or warning information to ensure driving safety.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a system and method for estimating the road surface adhesion coefficient of the whole road network. Background technique [0002] In the existing technology, when driving a vehicle in rainy and snowy weather, the vehicle often slips due to the low adhesion coefficient of the road surface, resulting in traffic accidents and endangering the safety of personnel and vehicles. How to know the road conditions ahead to avoid danger is an urgent need solved problem. Contents of the invention [0003] The purpose of the present invention is to provide a system and method for estimating the road surface adhesion coefficient of the whole road network, so as to solve the problem of traffic accidents caused by low road surface adhesion coefficient in the prior art. [0004] In order to achieve the above object, the present invention provides a system for predicting the adhesio...
