The invention provides a vehicle engine reverse rotation prevention control method and system.The method comprises the steps that when it is detected that a hybrid power system in a hybrid power vehicle is in a running state in real time, the first rotating speed of an engine in the hybrid power vehicle is monitored in real time; monitoring a second rotating speed of a generator in the hybrid vehicle in real time, and matching a first torque limit corresponding to the generator in real time according to the first rotating speed; matching a second torque limit corresponding to the generator in real time according to the second rotating speed, and performing minimization processing on the first torque limit and the second torque limit to generate a corresponding target torque limit in real time; and the target torque limit is correspondingly transmitted to a motor controller in the hybrid vehicle based on a preset rule, so that the motor controller completes corresponding torque control. The limiting torque of the engine and the generator can be accurately controlled, the reverse rotation phenomenon of the engine can be prevented, and the user experience is improved.

    本发明提供了一种车辆发动机防反转控制方法及系统,方法包括当实时检测到混动车辆内部的混动系统处于运行状态时,实时监控所述混动车辆内部的发动机的第一转速;实时监控所述混动车辆内部的发电机的第二转速,并实时根据所述第一转速匹配出与所述发电机对应的第一扭矩限制;实时根据所述第二转速匹配出与所述发电机对应的第二扭矩限制,并对所述第一扭矩限制以及所述第二扭矩限制进行取小处理,以实时生成对应的目标扭矩限制;基于预设规则将所述目标扭矩限制对应传输至所述混动车辆内部的电机控制器,以使所述电机控制器完成对应的扭矩控制。本发明能够精确的控制发动机以及发电机的限制扭矩,能够防止发动机出现反转的现象,提升了用户体验。
