The invention relates to a torque coordination method during series-parallel connection switching, torque coordination equipment and a computer readable storage medium. The torque coordination method comprises the following steps: controlling a driving motor to work according to a target torque; the current rotating speed of the driving motor and the target torque of the engine in the parallel connection mode are obtained, and the engine is controlled to work according to the target torque in the parallel connection mode to achieve speed regulation of the engine; if the rotating speed of the engine and the rotating speed of the driving motor meet the set conditions, the clutch is controlled to be closed; and the torque of the engine is kept unchanged, and the torque of the ISG motor is unloaded. The invention provides a torque coordination method and torque coordination equipment during series-parallel connection switching and a computer readable storage medium, the problem of torque impact in the parallel connection torque coordination process is solved, and better driving performance and driving comfort are obtained.

    本发明涉及一种串并联切换时的扭矩协调方法、扭矩协调设备及计算机可读存储介质。该扭矩协调方法包括步骤:控制驱动电机按照目标扭矩工作;获取当前驱动电机的转速和发动机在并联模式下的目标扭矩,控制发动机按照并联模式下的目标扭矩工作以实现发动机的调速;若发动机的转速和驱动电机的转速符合设定条件,则控制离合器闭合;保持发动机扭矩不变,卸载ISG电机扭矩。本发明提出了一种串并联切换时的扭矩协调方法、扭矩协调设备及计算机可读存储介质,解决了并联扭矩协调过程中的扭矩冲击问题,获得更好的驾驶性能和行车舒适性。
