Electric automobile traveling path planning method based on driving working condition

Abstract

The invention provides an electric automobile traveling path planning method based on a driving working condition. The electric automobile traveling path planning method comprises the following steps:step 1: determining a starting point and a finishing point; loading road network information, an average speed of each road section, uphill information of each road section and road section congestion information; setting a default initial speed v0 of an automobile vehicle; automatically detecting current residual total energy of an the electric automobile by a system; step 2, planning a shortestpath L0 according to the starting point and the finishing point by utilizing a shortest path Dijkstra algorithm; step 3, carrying out energy consumption analysis on the L0, calculating total energy consumption and judging whether the total energy consumption can reach or not, wherein the energy consumption analysis is divided into energy consumption of next 2 kilometers in the future, energy consumption from a residual road section of to the finishing point and extra energy consumption caused by uphill. According to the electric automobile traveling path planning method provided by the invention, a charging pile and the road network information of a road are effectively combined; a driving process considers the average speed which is dynamically calculated and a road grade which are dynamically calculated, and an electric automobile traveling path planning process is finished relatively well; a route can be more accurately planned for a user.

Description

technical field [0001] The invention relates to a travel path planning method for an electric vehicle based on driving conditions. technical background [0002] With the substantial increase in urban car ownership, traditional car pollutant emissions have become the main source of urban air pollution, seriously threatening the health of residents. Therefore, my country is vigorously developing new energy vehicles, especially electric vehicles. However, the development of electric vehicles at this stage is still limited by the lack of infrastructure such as charging and swapping stations and charging piles. Therefore, when using electric vehicles to travel, it is also necessary to consider whether the remaining power of the electric vehicle is sufficient to reach the destination when planning the route. Problems such as charging on the way. Contents of the invention [0003] In order to overcome the shortcomings of the existing route planning that does not take into accoun...
