Vehicle speed control method and device based on cloud platform

Abstract

The invention discloses a vehicle speed control method based on a cloud platform, and the method comprises the steps: acquiring first vehicle speed information of a first vehicle; acquiring second vehicle speed information of a second vehicle in a first predetermined area based on big data of the cloud platform; acquiring first path information and second path information of the first vehicle andthe second vehicle, judging whether an overlapped road section exists or not, and acquiring information of the road section; judging whether the first vehicle and the second vehicle are adjacent vehicles or not by acquiring first position information and second position information; if yes, acquiring first distance information, judging whether the first vehicle speed information and the second vehicle speed information are within a preset safety range or not, and whether the first vehicle speed and the second vehicle speed need to be adjusted or not is judged. By means of the technical scheme,the technical effects that the vehicle speed and the path of the surrounding vehicles are obtained based on big data to adjust the vehicle speed, accidents are avoided by integrating various factors,and the accident rate is reduced are achieved.

Description

technical field [0001] The invention relates to the field of vehicle speed control methods, in particular to a cloud platform-based vehicle speed control method and device. Background technique [0002] With the rapid development of the national economy, expressways extend in all directions, and at the same time, there are more and more cars. Due to the high density of cars on the roads in our country, traffic congestion is serious and traffic accidents occur frequently. Speed ​​limit is a simple and effective traffic management measure to reduce the average speed of vehicles on the road, so as to achieve the multiple purposes of ensuring traffic safety, reducing energy consumption and reducing vehicle exhaust emissions. Traffic management speed limit is a worldwide problem involving public traffic safety, because it directly affects traffic safety, traffic operation efficiency and economic efficiency. [0003] However, in the process of realizing the technical solution of ...
