Abstract
Provided is a vehicle navigation method based on an improved A-star (A*) algorithm, relating to the technical field of path panning. The method includes: converting a regional map for path planning into a grid map; planning a target travel path of an automated guided vehicle from a starting point to a target point on the grid map by using an improved A* algorithm, where the improved A* algorithm is an A* algorithm incorporating turning costs into a cost function; and navigating the automated guided vehicle along the target travel path. The method reduces the turning costs and improves navigation efficiency.
