混合动力汽车及其模式切换控制方法和装置
摘要：
本发明公开了一种混合动力汽车及其模式切换控制方法和装置所述方法包括以下步骤：当所述混合动力汽车从纯电动模式向混合动力模式切换时，控制所述发动机点火启动，并在所述发动机的转速达到预设的目标转速之前控制所述第二电机的输出扭矩达到所述混合动力汽车的需求扭矩；在所述发动机的转速达到所述预设的目标转速时控制所述发动机和所述第二电机同时进行扭矩输出，以使所述混合动力汽车切换至所述混合动力模式，其中，所述第二电机的输出扭矩与所述发动机的输出扭矩之和为所述需求扭矩，从而混合动力汽车从纯电动模式切换至混合动力模式时不会出现动力中断，增强汽车操纵稳定性及平顺性，提升用户的体验。
摘要（英）：

The invention discloses a hybrid vehicle and a mode switching control method and device thereof. The mode switching control method comprises the following steps that when the mode of the hybrid vehicle is switched from a full electric mode to a hybrid power mode, an engine is controlled to be ignited and started, and the output torque of a second motor is controlled to reach the required torque of the hybrid vehicle before the rotating speed of the engine reaches the preset target rotating speed; and when the rotating speed of the engine reaches the preset target rotating speed, the engine and the second motor are controlled to simultaneously conduct torque output so that the mode of the hybrid vehicle can be switched into the hybrid power mode, specifically, the sum of the output torque of the second motor and the output torque of the engine is the required torque, accordingly, power interruption can be avoided when the mode of the hybrid vehicle is switched from the full electric mode to the hybrid power mode, the operation stability and smoothness of the vehicle are improved, and the user experience is improved.
