The invention provides a heating ventilation and cooling system for a vehicle. A method of operating a start-stop vehicle having an HVAC system that does not include an electrically assisted coolant pump for circulating hot coolant to a heater core of the HVAC system in an engine off state of the vehicle, the method includes forcibly driving the vehicle via the engine in an environment with an external ambient temperature of about 30 degrees Fahrenheit or less, entering an auto-stop event such that the engine enters an engine off state, and circulating heated air into a cabin of the vehicle for at least one minute in the engine off state. The heated air is circulated by reducing a rotational speed of a blower motor, adjusting a recirculation door position to increase air recirculation, and adjusting a temperature mix door position toward a full heating position based on a sensed engine coolant temperature and a sensed evaporator core temperature.

    本公开提供了“用于车辆的加热通风和冷却系统”。一种操作具有HVAC系统的启停车辆的方法,所述HVAC系统不包括用于在车辆的发动机关闭状态下将热冷却剂循环到HVAC系统的加热器芯体的电动辅助冷却剂泵,所述方法包括以下步骤:在外部环境温度约30华氏度或低于30华氏度的环境中经由发动机强制驱动车辆,进入自动停止事件,使得发动机进入发动机关闭状态,以及在发动机关闭状态下将加热后的空气循环到车辆的车厢中达至少一分钟。加热后的空气通过以下方式进行循环:降低鼓风机马达的转速,调整再循环门位置以增加空气再循环,以及基于感测到的发动机冷却剂温度和感测到的蒸发器芯体温度将温度混合门位置朝向完全加热位置调整。
