在混合动力汽车中,动力源功率的合理匹配是影响整车性能的最主要的因素。混合动力汽车的控制策略及结构决定了整车的行驶性能和燃油经济性。由于常规的逻辑门限值控制方法很难从精确定量的尺度上确定相关控制参数的值,所以采用模糊控制策略。根据对常用汽车仿真软件ADVISOR的主要功能和仿真过程的掌握,针对其局限性对软件进行二次开发,构建基于模糊转矩控制策略的仿真模型,实现发动机和电机转矩的合理分配。
About the hybrid Electric vehicle, the reasonable match the power of the power producer is the most important factor of the Vehicle performance. Hybrid electric vehicle control strategy and structure determines the vehicle's driving performance and fuel economy. Since conventional logic threshold control is very diflficult to scale from a precise quantitative values to determine the relevant control pa- rameters, so use the fuzzy control strategy. Used cars based on the main functions ADVISOR simulation software and simulation process control, limitations on the software for its second development, build torque control strategy based on fuzzy simulation model of the engine and the motor torque to achieve a reasonable distribution.
