摘要
针对并联式混合动力车动力系统中发动机和电动机驱动系统之间存在的能量分配和转矩协调问题,以发动机高效率、低能耗工作为目的,建立了并联式混合动力车动力系统传动模型,以发动机稳态特性图和超级电容SOC值为主要依据,设计了发动机和电动机间的转矩分配控制策略,并运用电动机补偿转矩方法设计两者之间的转矩协调控制策略。仿真结果表明:控制策略能够实时动态地控制发动机和电动机的转矩分配与协调问题,可有效地控制混合动力系统在高效区工作,既满足了系统动力性需求,又提高了燃油的经济性。
Aiming at the problem of energy distribution and torque coordination which existed in the Parallel Hybrid Electric Ve- hicle （PHEV） dynamical system between engine and electrically driven system,the simulation model of the PHEV dynamic sys- tem was established for the purpose of keeping the engine operating in high efficiency, and based on the engine efficiency and ul- Ira capacitor SOC value, torque distribution strategy between the engine and motor is designed, and torque coordination strategy is designed by the way of motor torque compensation. Result shown that ： torque distribution and coordination can be controlled effec- tively, and PHEV work on the high-efficiency area, and power performance and oil efficiency is improved.
