The control strategy for series hybrid tractor is formulated in this paper. The driving mode and target vehicle speed are based on the accelerator pedal signal and the driver’s response to the control panel switches, then the drive demand power could be calculated. The charging power of the battery is based on the battery SOC, and the engine operating point could be determined by both. By controlling the generator, the ECU is assisted to effectively control the engine operating point. The physical model is established by MATLAB/Simulink, and the normal sea state and extreme sea state are simulated. Through the simulation results analysis, the total fuel consumption of the engine under normal and extreme sea conditions is 1.012L and 1.973L respectively, and the efficiency of the engine under extreme sea conditions can be maintained above 40% for a long time.
