The invention discloses a hybrid engine idle speed control method and device, a controller and a storage medium, and the method comprises the steps that on the basis of an idle speed target rotating speed needed by an engine and an obtained actual rotating speed of the engine, an idle speed demand torque is obtained through a PID adjusting method; the idle speed demand torque is processed, and a dynamic part torque and a static part torque are obtained; based on a preset demand torque distribution method, the dynamic part torque and the static part torque are processed, and the total engine demand torque and the total motor demand torque are obtained; and based on the engine total demand torque and the motor total demand torque, controlling the engine and the motor to operate at idle speed. By means of the scheme, the problem that in the related technology, engine emission and oil consumption are difficult to balance can be solved.

    本申请公开了一种混合发动机怠速控制方法、装置、控制器和存储介质,其中方法包括:基于发动机所需的怠速目标转速和获取到的发动机实际转速,利用PID调节方法,得到怠速需求扭矩;处理怠速需求扭矩,得到动态部分扭矩和静态部分扭矩;基于预设有的需求扭矩分配方法,处理动态部分扭矩和静态部分扭矩,得到发动机总需求扭矩和电机总需求扭矩;基于发动机总需求扭矩和电机总需求扭矩,控制发动机和电机怠速运行。本申请通过上述方案,能够解决相关技术中发动机排放和油耗难以得到平衡的问题。
