The invention relates to the technical field of intelligent driving, and discloses an urban logistics vehicle intelligent driving-human driving mode switching method considering driving risks and energy consumption. Comprising the steps of driver mode switching driving data extraction, mode switching interval acquisition considering driver styles and surrounding vehicle trajectory prediction, and mode switching opportunity optimization based on driving risks and limit energy consumption. The method comprises the following steps of: obtaining a risk interval and a risk change curve of a mode switching decision by combining a style identification result and utilizing a risk evaluation model according to historical characteristic data and surrounding vehicle track prediction in a driver mode switching process, and obtaining a time interval of the mode switching decision based on the risk interval and the risk change curve; and finally, an optimization model is established based on human driving mode speed prediction, and the switching opportunity is optimized. According to the method, the driving risk and the driving energy consumption are comprehensively considered, the problems of high driving energy consumption and insufficient safety caused by unreasonable man-machine co-driving mode switching of the intelligent driving logistics vehicle in a complex urban scene are effectively solved, and the passing efficiency of the urban logistics vehicle is improved.
