The invention discloses a heating control method for an extended-range electric vehicle, which comprises the following steps: step S20, an air conditioner control panel sends a heating or defrosting request, the request is transmitted to a vehicle control unit through a gateway, whether an engine is in a non-starting state or not is judged, if not, a current driving mode is kept, if yes, the step S21 and the step S21 are executed, and if not, the step S20 is executed; the VCU judges whether to enter a range extending mode or not in a delayed mode, if yes, the step S22 is executed, if not, the current driving mode is kept, the step S22 enters the range extending mode and sends a starting instruction to the APU to start execution, and the step S24 is executed when an engine is started and a CLM sends a heating or defrosting request or not and whether a driver at the MP5 end manually selects a switching mode to be an electric (EV) mode or not. If not, the current driving mode is kept, and if yes, the step S25 is carried out, and the problem that the cost is high due to the fact that an extended-range electric vehicle at the present stage adopts engine waste heat and PTC to jointly provide a heat source for a cab passenger compartment for cab heating is solved.
本发明公开了一种增程式电动汽车采暖控制方法,包括以下步骤:步骤S20,空调控制面板发出采暖或除霜请求,请求经过网关传输给整车控制器,且发动机是否处于未启动状态,若否则保持当前驱动模式,若是进入步骤S21,步骤S21,VCU延时判断是否可以进入增程模式,若是则进行步骤S22,若否则保持当前驱动模式,步骤S22,进入增程模式,将启机指令发送给APU开始执行,步骤S24,在发动机已启动,CLM已发出采暖或除霜请求的的状态下,在MP5端驾驶员是否手动选择切换模式为电动(EV)模式,若否则保持当前驱动模式,若是则进行步骤S25,现阶段的增程式电动汽车采用发动机余热和PTC共同为驾驶室乘员舱提供热源用于驾驶室采暖,成本较高的问题。
