In a traditional power supply system of an automobile, an engine directly drives an automobile generator through a belt, and a storage battery is charged while electric energy is supplied to an electric appliance on the automobile. The energy-saving and emission-reducing system is also used for generating power by using the inertia kinetic energy of the automobile and charging the battery pack of the electric automobile, but the utilization rate of the inertia kinetic energy of the automobile is still low. In some long downhill sections, when an accelerator is not stepped on for acceleration, the engine does not directly drive the motor vehicle to move, because the gravitational potential energy of the motor vehicle is enough to be converted into the kinetic energy of the motor vehicle, the motor vehicle can move, but the current motor vehicle can not directly turn off the engine to avoid the failure of steering and braking, and the oil consumption of the motor vehicle can not be reduced by utilizing the downhill sections.
