Abstract

The invention discloses a cloud platform based electric automobile path planning method. The method comprises steps as follows: the deployment conditions of charging piles of the entire network as well as traveling data of an electric automobile are collected through a cloud platform in real time, the traveling path data of the automobile are calculated by a vehicle navigation system, reasonable traveling paths, such as a path with the shortest traveling time, a path with the shortest traveling distance and a path recommended by the cloud platform, of the electric automobile are planned in advance according to the use saturation degree of the charging piles, the path recommended by the cloud platform is selected on the basis of shorter increased time, shorter detouring distance and preferable use of the charging piles with low saturation degree, then the cloud platform sends the paths to a user, and the user selects one path according to individual demand and reserves the corresponding charging pile through the cloud platform. According to the method, the reasonable traveling path can be planned for the electric automobile, the difficulty of finding the charging piles for the electric automobile is reduced, and the utilization rate of the charging piles of the entire network is effectively balanced.

Description

technical field

[0001] The invention relates to the technical field of electric vehicles and computer communication, in particular to a cloud platform-based path planning method for electric vehicles. Background technique

[0002] With the in-depth study of path planning theory, the existing navigation system has been able to calculate the shortest distance path and the shortest time path, so as to plan the driving route for car travel. For traditional fuel vehicles using gasoline and diesel, the route planning of the existing navigation system can well meet the demand. Because the deployment of gasoline and diesel gas stations is very common, the refueling process of cars is also very convenient, and the driving distance of a car is long, so it is not difficult for cars using this traditional fuel to find a gas station before the fuel is exhausted. The process also doesn't require long queue times, and the navigation system usually doesn't have to think about refueling whe...
