摘　　要：为解决串联式混合动力车辆动力单元突加重载时发动机转矩负荷率过高导致运行异常的问题,设计了一种基于模糊控制的载荷补偿策略,通过控制发电机转矩来调节发动机转矩负荷率,避免发动机在临界条件工作。仿真和试验结果表明,该策略有效改善了动力单元工作特性,使其可以稳定平滑地过渡到预期工作点,提高了动力单元工作的鲁棒性。When the power unit of the series hybrid vehicle is overloaded suddenly,the engine torque load rate would be too high,which would lead to abnormally operation.In order to solve this problem,a load compensation strategy based on fuzzy control is designed.By controlling the torque of generator,the engine torque load rate could be regulated,so that avoiding the engine working near the critical condition.The simulation and test results show that the strategy improves the working characteristics of the power unit effectively,makes it operates stable and smoothly until achieve the expected operating point,improves the robustness of the power unit.
