The invention relates to a vehicle flameout control method, a vehicle flameout control system, a power train for a vehicle and a hybrid vehicle. The vehicle flameout control method comprises the following steps that S1, when an engine enters a flameout working condition, whether the condition that a motor activates an auxiliary flameout mode is met or not is judged, if yes, the step S2 is executed, and if not, the step S1 continues to be executed; s2, simulating and establishing an engine rotating speed model according to the actual rotating speed signal of the engine; s3, calculating the real-time fluctuation torque of the engine according to the engine rotating speed model; and S4, the motor is commanded to send a negative torque instruction capable of being adjusted in real time according to the fluctuation torque. By means of the vehicle flameout control method, the problem of noise generated in the flameout process of the hybrid power vehicle provided with the dual-mass flywheel can be effectively solved.
本发明涉及车辆熄火的控制方法、车辆熄火的控制系统、用于车辆的动力传动系以及混合动力车辆。该车辆熄火的控制方法包括以下步骤：S1，当发动机进入熄火工况，判断是否满足电机激活辅助熄火模式条件，如果满足，执行步骤S2，如果不满足继续执行步骤S1；S2，根据发动机的实际转速信号模拟建立发动机转速模型；S3，根据所述发动机转速模型，计算发动机实时的波动力矩；S4，命令电机根据所述波动力矩发出可实时调整的负扭矩指令。本发明的车辆熄火的控制方法能够有效解决配有双质量飞轮的混合动力车辆在熄火过程中发生的噪音问题。
