Abstract

The invention discloses a global path planning method and system based on energy consumption economy. The method comprises the following steps: establishing a vehicle energy consumption model according to relevant parameters of vehicle dynamic property in advance, and establishing a real-time traffic model according to section parameters, map information and real-time traffic information; establishing an energy consumption map according to the vehicle energy consumption model and the real-time traffic model; determining a path according to the energy consumption map, a starting point and a target point. The path planned through the method is the lowest in path, and relatively optimal duration and / path length can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a global path planning method and system based on energy consumption economy. Background technique [0002] Path planning is one of the basic links of unmanned vehicle navigation. It is to search for an optimal or approximately optimal non-collision path from the starting point to the target point according to a certain performance index, which can be divided into two types: the first The first is macro path planning, also called global path planning; the second is local path planning. Global path planning can optimize the planned path, and local path planning can enable unmanned vehicles to complete real-time obstacle avoidance. [0003] The existing global path planning methods are mainly based on the shortest path or the shortest time, and do not take the energy consumption economy into the path planning considerations, resulting in high energy consumption in...
