Problems solved by technology

At present, the road condition information synchronization method of the expressway mainly relies on the road condition LED screen, navigation or broadcasting. The traditional method has certain limitations and cannot effectively synchronize the current environment and surrounding vehicle information to the target vehicle, especially in extreme weather (rainy days, large Fog, night, etc.) information on road conditions and surrounding vehicles is particularly important

Abstract

The invention discloses a vehicle speed guiding method. According to the vehicle speed guiding method, according to the change of traveling states of a target vehicle in different detecting areas, theinfluence of adjacent vehicles on the target vehicle is calculated in real time, and it is ensured that the vehicle can travel more reasonably and safely under the influence of the surrounding vehicles; and the traveling conditions of the surrounding vehicles are comprehensively applied, so that the calculating result is more accurate and more reasonable, high real-time performance is achieved, meanwhile, the driving environment can also be adjusted more efficiently, and the passing rate of a road is increased.

Description

technical field [0001] The invention belongs to the field of Internet of Vehicles and relates to a vehicle speed guidance method. Background technique [0002] The Internet of Vehicles is based on the intra-vehicle network, the inter-vehicle network and the wide area network, and is assisted by various sensors to realize the interaction and sharing of information inside the vehicle, between vehicles, and between vehicles and the Internet, so as to improve road traffic control and road safety. traffic safety capabilities. [0003] In recent years, highway traffic safety and congestion problems have frequently appeared in the public eye. A considerable part of the accidents are caused by excessive speed. How to reduce the occurrence of accidents through technical means has become a research hotspot. At present, the road condition information synchronization method of the expressway mainly relies on the road condition LED screen, navigation or broadcasting. The traditional met...
