Abstract: It takes the loader of parallel hybrid power as the object to study the control strategy. Through analyzing the working character of a five-ton loader's load spectrum, the control method of fuzzy logic was put forward. Take the required torque of system which was estimated online and super capacitor's SOC as the input to get output torque of engine and electromotor. The result shows that the control strategy raises the fuel economy of the engine. Comparing with traditional loader, it can save about 7.8% fuel and achieve the goal of energy-saving.

Key words: automatic control technology, loader, hybrid power, energy-saving, control strategy, fuzzy logic
