Recursive-type path-planning method of electric vehicle

A recursive-type path-planning method of electric vehicle comprising the following steps: inputting state conditions, which include at least a starting position, at least a destination position, a residual mileage of the electric quantity, and a path distance between the starting position and the destination position; searching all available charging stations within a range according to the longitudes and latitudes of the starting position and the destination position; calculating the distances between the charging station to the starting position and the destination position one by one; filtering out and removing the charging stations which do not conform to the searching condition one by one; integrating a list of charging stations and planing at least a travel path of the electric vehicle; when any one of the state conditions changes, executing the loop of step a-e, so as to re-gain a travel path for the electric vehicle. In this way, the charging stations on the paths can be connected in series step by st
