Description

technical field [0001] The invention relates to an intelligent inertial energy-saving system of an unmanned vehicle and a control method thereof. Background technique [0002] Despite strong policy support, pure electric vehicle technology has not been widely promoted due to the high cost of vehicle power batteries, low battery energy density, limited mileage, and charging piles are far from popular. "Technical Roadmap for Energy-Saving and New Energy Vehicles" pointed out that energy-saving vehicles should vigorously develop high-efficiency drive trains and reduce internal resistance and friction of drive trains. Inertial energy utilization technology fully meets this requirement. [0003] In recent years, inertial energy utilization technology has increasingly become one of the research and development hotspots. Japan's Toyota, Honda, Germany's Mercedes-Benz, BMW, Audi, etc. have successively added cars that use inertial energy randomly, but they can only use inertial en...
