Electric automobile optimal path finding method based on power consumption

Abstract

The invention provides an electric automobile optimal path finding method based on power consumption, and belongs to the technical field of electric automobile driving. The method includes the steps of calculating the path, namely, a first class path where the power consumption between the starting point and the ending point is the minimum, according to the starting point, the ending point and the storage battery residual electric quantity, namely, the first storage battery electric quantity, comparing the first storage battery electric quantity with the first class power consumption, and determining the optimal path according to the comparison result. The path finding scheme with the minimum power consumption between the starting point and the ending point as the index is put forward for the current situation that the running mileage of electric automobiles is poor. Meanwhile, road condition information is obtained through the real-time communication technology, and therefore the optimal path closest to the actual condition can be obtained.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle driving, and relates to a method for finding the optimal route of the electric vehicle. Background technique [0002] Under the dual needs of environmental protection and occupation of the commanding heights of the industry, the development of new energy vehicles has become the future industry direction of China and even the world. Pure electric vehicles save the fuel tank, engine, transmission, cooling system and exhaust system. Compared with the internal combustion gasoline engine power system of traditional vehicles, the cost of electric motors and controllers is lower, and the energy conversion efficiency of pure electric vehicles is higher. Because the energy source of electric vehicles - electricity, comes from large generator sets, its efficiency is unmatched by small gasoline engines or even hybrid engines, and the cost of using pure electric vehicles is falling, so pure electric ...

Problems solved by technology

However, in this paper, the traffic conditions are not considered, but the car is assumed to be traveling at the same speed; the impact of different traffic conditions on the power consumption of the car is not considered, and the foothold of the paper is still that the user travels according to the shortest path

[0007] The above papers have proposed route optimization for fuel vehicles or electric vehicles, but they have not taken the least power consumption of electric vehicles as an index; Charge
