However, due to the imperfect development of battery and charging technology of electric vehicles, the rated driving range of driverless electric logistics vehicles is generally not high, and the actual driving range is less than the rated driving range . Therefore, it is necessary to study the path optimization problem. In this study, a mathematical model of the route optimization problem of driverless electric logistics vehicle is proposed, and the rationality of the model is verified by using LINGO software to test a small scale example. Then, the traditional C-W algorithm is improved, and it is used to solve the mathematical model in this paper. MATLAB software is used to solve the small-scale example to verify the feasibility of the algorithm. Finally, a large scale example is solved by th
