The invention relates to a parallel control method for a hybrid power vehicle, a vehicle control unit and a system. The method comprises the following steps that when it is detected that a vehicle meets a preset condition for entering parallel connection, the vehicle is controlled to enter a parallel connection driving mode; the engine torque is controlled to be adjusted to the engine target torque, the engine rotating speed is controlled to be adjusted to the engine target rotating speed, and the engine flywheel end torque is controlled to be adjusted to the target flywheel end torque; when it is detected that the engine flywheel end torque is adjusted to be the preset torque, a clutch is controlled to be attached, and the front end of the clutch has no torque; the clutch fitting state is obtained, when it is detected that the clutch fitting state is that fitting is completed, the working mode of the generator is switched, and the torque of the generator after mode switching is transferred to a driving motor; therefore, the hybrid electric vehicle can quickly and stably enter the parallel drive mode from the series drive mode.

    本发明涉及一种混动车进并联控制方法、整车控制器及系统。该方法包括如下步骤:当检测到车辆满足进入并联的预设条件时,控制车辆进入并联驱动模式;控制发动机扭矩调整为发动机目标扭矩,控制发动机转速调整为发动机目标转速,控制发动机飞轮端扭矩调整为目标飞轮端扭矩;当检测到发动机飞轮端扭矩调整为预设扭矩后,控制离合器贴合,并使离合器前端无扭矩;获取离合器贴合状态,当检测到所述离合器贴合状态为已贴合完成时,对发电机的工作模式进行模式切换,并将模式切换后的发电机扭矩转移至驱动电机;因此可使混动车快速平稳的由串联驱动模式进入并联驱动模式。
