Method and device for planning route of electric car

Abstract

The invention provides a method and a device for planning a route of an electric car, which are used for providing a global optimum route to the running of the electric card, and can get ready for the next travelling after the electric car arrives at the destination. The method comprises the following steps: determining the position information of each candidate charging station and each candidate charging station sequence according to acquired predetermined starting position information, destination position information, charging facility information of the destination and initial electric quantity; aiming at each candidate charging station sequence, respectively calculating the route parameters from the starting point, through the candidate charging stations included in the candidate charging station sequence in sequence and to the destination point, and selecting the optimal route according to the route parameter of each candidate charging station sequence and a predetermined route selection rule.

Description

technical field [0001] The invention relates to a path planning method, in particular to a path planning method and device for an electric vehicle. Background technique [0002] The environment and energy are hot issues in the world at present. In order to alleviate the pressure on the environment and energy, electric vehicles have received widespread attention at home and abroad. Compared with traditional cars, electric vehicles have been developed rapidly due to the advantages of low noise, no pollution and energy saving. [0003] Among them, the battery is an important part of the electric vehicle, and it is also the main factor restricting the maximum mileage (that is, the cruising range) of the electric vehicle. The electric vehicle often needs to find a charging station for charging during driving. However, path planning for traditional vehicles cannot be directly used for electric vehicles because it does not take into account factors such as the cruising range of th...

[0003] Among them, the battery is an important part of the electric vehicle, and it is also the main factor restricting the maximum mileage (that is, the cruising range) of the electric vehicle. The electric vehicle often needs to find a charging station for charging during driving. It is very important to carry out path planning, and the path planning of traditional vehicles cannot be directly used for electric vehicles because it does not consider factors such as the cruising range of the vehicle's initial power and the distribution of charging stations.
