Electromobile navigation method and device based on positions of charging piles

Abstract

The invention discloses an electromobile navigation method and device based on positions of charging piles. The navigation method comprises the following steps: 1, obtaining position information of a current electromobile, position information of the charging piles, destination information and current remain continuous navigation mileage information in real time through satellite navigation to calculate the distance to the destination directly and the distance to the nearest charging pile; 2, judging the magnitude of the distance to the destination directly and the current remain continuous navigation mileage information; 3, when the distance to the destination directly is less than or equal to the current remain continuous navigation mileage information, planning the route to the destination directly. According to the navigation method, the navigation route can be automatically planned according to the current automobile remain continuous navigation mileage and the periphery charging pile distribution condition, and a user can reach the destination without trouble.

Description

technical field [0001] The present invention relates to the field of electric vehicle navigation, in particular to a navigation method for electric vehicles based on the location of charging piles and a navigation device used for the method. Background technique [0002] With the vigorous promotion and promotion of electric vehicles in our country, more and more manufacturers have launched pure electric vehicles, and the market acceptance of electric vehicles is also getting higher and higher, which is about to usher in explosive growth. However, electric vehicles have a short mileage on one charge, few charging piles, and the problem of difficulty in charging has been plaguing the users of pure electric vehicles. Self-funded project: (English) Supported by National Natural Science Foundation of China (Grant No.61401004) (Chinese) National Natural Science Foundation of China (No. 61401004) Research on sparse representation of network multimedia stream QoS features and flexib...

Problems solved by technology

[0004] The object of the present invention is to provide a navigation method for an electric vehicle based on the location of a charging pile and a navigation device thereof. Information, navigation information and the remaining mileage information of the vehicle itself are combined, and it is not convenient to use. It is realized that only by inputting the destination, it can automatically plan according to the remaining mileage of the current car and the distribution of surrounding charging piles. Navigation route to ensure that users can reach their destination smoothly
