Navigation path planning method, device and system

Abstract

The embodiment of the invention relates to the technical field of new energy automobile navigation, and discloses a navigation path planning method. The method comprises the following steps: a navigation device sends navigation path planning related data information and residual electric quantity information to an energy consumption model server, and when the residual endurance mileage corresponding to the residual electric quantity information is smaller than a preset first distance threshold, the navigation device receives a first path plan sent by the energy consumption model server, the first path planning comprises the shortest time, the shortest distance and high-speed priority. By applying the technical scheme of the invention, the energy consumption under the current driving condition can be calculated based on the driving habit data of the user, and when the remaining endurance mileage corresponding to the remaining electric quantity information is smaller than the preset first distance threshold value, the shortest-time shortest-distance high-speed priority path planning is provided, so that the driving experience of the user is improved. The problem that a user cannot reach a destination due to insufficient residual electric quantity is solved, and meanwhile the problems of energy supplement worry and mileage anxiety of the user of the pure electric vehicle are solved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of new energy vehicle navigation, and specifically relate to a navigation path planning method, device, and system. Background technique [0002] Most of the current new energy vehicle users come from traditional fuel vehicles, and their driving habits are closer to fuel vehicles. At present, the battery life of new energy vehicles, especially pure electric vehicles, is quite different from that of traditional fuel vehicles under different driving conditions, which leads to inaccurate estimates of the remaining mileage of the vehicle by users, which in turn easily causes anxiety about the driving range of users. [0003] During the driving of new energy vehicles, the user mainly estimates the mileage of the vehicle based on the vehicle SOC (remaining power), and then judges whether to supplement the vehicle based on the mileage and the mileage between the vehicle and the destination...
