The invention discloses an engine starting control method and device, a vehicle, a computer readable storage medium and a computer program product. The control method comprises the following steps: judging whether a current gear is a D gear or not; if the current gear is the D gear, oil pressure corresponding to the maximum sliding friction torque is applied to the clutch according to the maximum sliding friction torque capable of being borne by the clutch; the driving motor is controlled to increase additional dragging torque on the basis of the original torque requirement; and when the rotating speed of the engine reaches the ignition rotating speed, oil pressure of the clutch is removed, and meanwhile the dragging torque additionally applied by the driving motor is controlled to be reset. Oil pressure is applied to the clutch through the hybrid power vehicle control unit, so that a driving disc and a driven disc of the clutch are attached, and the driven disc drives the driving disc to increase the rotating speed; the driving motor is controlled to increase additional dragging torque for starting the engine; when the engine reaches the ignition rotating speed, the engine automatically injects oil and ignites; the engine can be started under the condition that the generator cannot be dragged.
本发明公开了一种发动机起动控制方法、装置、车辆、计算机可读存储介质及计算机程序产品。该控制方法包括:判断当前档位是否在D档;如果当前档位在D档,根据离合器所能承受的最大滑摩扭矩向离合器施加最大滑摩扭矩对应的油压;控制驱动电机在原有扭矩需求基础上增加额外的拖拽扭矩;当发动机转速到达点火转速时,撤掉离合器的油压,同时控制驱动电机额外施加的拖拽扭矩清零。本发明实施例通过混合动力整车控制器向离合器施加油压,使离合器主从动盘贴合,从动盘带动主动盘转速上升;并且控制驱动电机增加额外的拖拽扭矩,用于使发动机起机;当发动机达到点火转速后,发动机自行喷油点火;实现了在发电机无法拖动的情况下使发动机起机。
