The invention relates to an engine starting method and device, a medium, equipment and a vehicle, and is applied to a hybrid power vehicle of a P2 power structure. The method comprises the steps of under the condition that the hybrid power vehicle enters a parallel connection mode, controlling the pressure of a clutch to be gradually increased and reach the critical point pressure of torque transmission and non-torque transmission; controlling a driving motor to drive an engine to run through the clutch until the rotating speed of the engine reaches the preset rotating speed, and adjusting the increment of the torque of the driving motor according to the pressure of the clutch in the process that the pressure of the clutch is increased from the critical point pressure to the target pressure corresponding to the preset rotating speed, so that the increment of the torque of the driving motor and the pressure of the clutch meet a preset corresponding relation; and when the rotating speed of the engine reaches the preset rotating speed, controlling the engine to ignite and regulating the speed to be consistent with the rotating speed of the input shaft. In this way, the torque increment part of the driving motor is applied to dragging of the engine, and therefore impact caused when the engine is started is reduced.

    本公开涉及一种发动机的起动方法和装置、介质、设备、车辆,应用于P2动力结构的混合动力车辆。方法包括:在混合动力车辆进入并联模式的情况下,控制离合器的压力逐渐增大并达到传扭与不传扭的临界点压力;控制驱动电机通过离合器带动发动机运转,直至发动机的转速达到预定转速,其中,在离合器的压力从临界点压力增大到与预定转速对应的目标压力的过程中,根据离合器的压力调节驱动电机扭矩的增量,以使驱动电机扭矩的增量与离合器的压力满足预定的对应关系;在发动机的转速达到预定转速的情况下,控制发动机点火并调速至与输入轴转速一致。这样,驱动电机的扭矩增量部分应用于发动机的拖拽,从而减小了发动机起动时造成的冲击。
