摘　　要：并联混合动力汽车在发动机和电动机工作过程中,需要根据路况进行能量分配和工作模式切换。以并联混合动力汽车在状态切换过程中总转矩不发生大的波动为控制目标,提出"转矩预分配+发动机调速+发动机动态转矩估计+电动机转矩补偿控制"的动态控制策略。以MATLAB为仿真平台,搭建了基于整车动态控制的仿真模型,对上述基本控制算法进行了定工况和全工况仿真验证。结果表明,在各种状态切换过程中,动态控制算法能有效控制混合动力系统的转矩波动,保证动力传递的平稳性。It is necessary for PHEV to distribute energy between engine and motor and to control state--switch during work. Aimed at keeping the total torque unchanging under state--switch, a dynamic control algorithm was put forward, which can be expressed as motor torque compensation for engine after torque pre--distribution, engine speed regulation and dynamic engine torque estimation. Taking MATLAB as the platform, a vehicle control simulation model was built, based on which the fundamental control algorithm was verified by simulation testing with fixed state--switch conditions and consecutive state--switch conditions. The results demonstrate that the dynamic control algorithm can effectively dampen torque fluctuations and ensure power transfer smoothly under various state-- switches.
