Electric vehicle travel path planning is an important part of the new energy vehicle intelligent travel.In the background of advocating electric car travel and urban road congestion,accurate and effective electric vehicle path planning services can provide the best charge Program for the travelers,which have brought great convenience.In this paper,we mainly study a travel path algorithm for electric vehicle based on driving conditions.Through the optimization algorithm analysis,the problem is simulated and the result of the model simulation is consistent with the experimental observation data,which makes the model more reliable.Specifically we have completed the following work:1.we have studied the research on the travel path planning of electric vehicle based on driving conditions,and the correlation analysis of the parameters is carried out.The simulation characteristics of the model are discussed based on the curve of battery residual power.2.the actual driving environment analysis,to determine the average vehicle speed and road slope for the impact of electric vehicle energy consumption of the main factors,and according to multiple actual test data modeling.3.compared with the existing conventional electric vehicle path planning algorithm,the use of sub-estimated electric vehicle energy consumption method to calculate the dynamic calculation of the average speed,taking into account the road slope on the electric car’s energy consumption.Finally,we compare the energy error and time error of the two algorithms,to prove the accuracy of electric car path planning algorithm in this paper.4.Through a large number of simulation and optimization experiments,the proposed algorithm is further optimized,considering the road congestion index,the optimal charging pile selection and the electric vehicle end stop condition,which improves the accuracy of the algorithm and enhances the practical application of the algorithm.5.The algorithm of this paper is verified by a model simulation,and a prototype system is designed to show that the algorithm has certain practicability.In this paper,based on the driving conditions of the electric vehicle travel planning algorithm and its application,combined with the charging pile,road network information,driving process taking into account the dynamic calculation of the average speed,road slope,better completed the electric vehicle path planning Process,can be more correct for the user planning routes,compared to the existing literature has been compared to the results of the basic to meet the normal driving needs,can be applied to the actual life.
