Method and device for dynamically searching charging piles for path planning and navigation method and device

Abstract

The invention discloses a method and device for dynamically searching charging piles for path planning and a navigation method and device. The method for dynamically searching charging piles for pathplanning comprises the steps of: calculating a residual mileage of a vehicle according to a current electricity state and destination information of the vehicle; when the residual mileage achieves a first preset mileage, searching charging piles according to current first position information of the vehicle; when charging piles are searched, carrying out path planning according to types of the charging piles, and generating and displaying a path planning result; and obtaining a first charging pile site selected by a user according to the path planning result, calculating path planning according to the first charging pile site and the first position information, and carrying out navigation. Through implementing the method for dynamically searching charging piles for path planning, availablecharging piles can be searched in real time, thereby effectively avoiding the condition that vehicles cannot supplement power before the power is exhausted, assisting and improving continuing mileageof the vehicles in the running process, decreasing the worry and scruple, for power insufficiency, of users in the process of driving electric cars, and enhancing the driving experience of the users.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging and navigation, in particular to a method and device for dynamically searching for charging pile path planning and navigation. Background technique [0002] In the current market, when users buy pure electric vehicles, there are two main concerns, one is the mileage problem, and the other is the charging problem. Even if charging piles can be searched through programs such as map APP, there will still be problems such as unavailable charging piles, charging piles being occupied, and charging piles not existing, but these problems cannot be timely and accurately fed back through the current map APP and other programs , is one of the most important reasons for users' "mileage anxiety". This problem will further lead to the difficulty of finding available charging piles. These are all problems to be solved urgently in the process of using electric vehicles. Contents of the inven...
