A method for controlling start-stop of a hybrid electric vehicle, comprising steps as following: acquiring a first start-stop instruction, and determining a first start-stop type of the vehicle according to the first start-stop instruction; acquiring a second start-stop instruction, and determining a second start-stop type of the vehicle according to the second start-stop instruction; and performing start-stop controlling on an engine according to priorities of the first start-stop type and the second start-stop type, charcterized in that the priorities are set as: the emergency stop has the highest priority; the priorities of the error stop and the power-off stop are higher than that of all start types; the priority of the error start is higher than that of the comfortable start, the dynamic start, and the normal stop; the priority of the dynamic start is higher than that of the comfortable start; the priorities of the dynamic start and the comfortable startup are higher than that of the normal stop, wherein: - the start of the vehicle under normal working conditions is a comfortable start, - the start when the vehicle needs power to respond quickly is a dynamic start, - when the vehicle is a hybrid vehicle, it is detected that the electric power system of the vehicle has a serious failure, and the start when the driving needs cannot be met is an error start, - the stop of the vehicle under normal working conditions is a normal stop, - the stop when the parts of the vehicle have a slight abnormality is an error stop, - the stop of the vehicle when the parts of the vehicle are in a serious abnormal situation or the vehicle is in an emergency situation is an emergency stop, - the stop of the vehicle when the whole vehicle is powered off is a power-off stop; and wherein the priorities are calibrated according to factors such as fuel consumption, vehicle driving safety, and personal safety of drivers and passengers and are preset in the control system of the vehicle, and the method further comprises monitoring real-time working condition of the vehicle and generating start-stop instructions according to the real-time working condition. acquiring a first start-stop instruction, and determining a first start-stop type of the vehicle according to the first start-stop instruction;
