The invention discloses an emission control method, system and device after cold start of a range extender and a medium. The emission control method comprises the steps that a hybrid control unit and a range extending system are powered on and awakened; the hybrid control unit obtains the starting trigger signal, generates an engine starting instruction and sends the engine starting instruction to the range extending system, and the range extending system obtains the engine starting instruction and starts emission control limitation; the current power-on circulation state of the range extender is judged based on the water temperature of the engine and the value of the ignition identification bit of the range extending system; if the value of the ignition identification bit of the range extending system is a preset value, the power limitation of the range extender is relieved; otherwise, when the water temperature of the engine does not exceed the preset threshold value T1; the power-on circulation state is in a first-time starting state, and the range extender executes power limitation; the first starting state comprises that the water temperature of the engine does not exceed a preset threshold value T1, and the value of the ignition identification bit is not a preset value. According to the emission control method, system and equipment and the medium, the emission control method improves the emission efficiency of the output power after the cold start of the vehicle.
一种增程器冷启动后的排放控制方法、系统、设备及介质,该排放控制方法包括:上电唤醒混动控制单元和增程系统;混动控制单元获取启动触发信号,生成发动机启动指令并发送至增程系统,增程系统获取发动机启动指令,启动排放控制限制;基于发动机水温和增程系统起燃标识位的值判定增程器当前的上电循环状态;若增程系统起燃标识位的值为预设值,则解除增程器功率限制;否则在发动机水温未超过预设阈值T1时;上电循环状态处于首次启动状态,增程器功率执行功率限制;首次启动状态包括:发动机水温未超过预设阈值T1且起燃标识位的值非预设值。本发明提供的排放控制方法、系统、设备及介质,该排放控制方法提升了车辆冷启动后输出功率的排放效能。
