热管理系统的控制方法和车辆
By controlling the operation of the heater and warm air pump in the event of a main control valve failure, combined with the engine start/stop status and thermal management demand signals, the problem of battery pack cooling and passenger compartment heating failure caused by the main control valve failure was solved. This enabled the normal operation of some thermal management functions, improving battery pack safety and passenger compartment comfort.

Abstract
本发明公开了一种热管理系统的控制方法和车辆，热管理系统的控制方法，包括：在所述主控制阀处于故障状态且所述车辆的电池工作状态为放电状态的条件下，判断是否接收到热管理需求信号，其中，热管理需求信号至少包括电池包冷却需求信号、电池包加热需求信号和乘员舱采暖需求信号中一种或多种；若是，则获取发动机的启停状态，并根据发动机的启停状态和 / 或热管理需求信号控制加热器的加热工作状态以及暖风水泵的开闭状态。采用该控制方法可以在主控制阀发生故障时实现部分有效的热管理功能，避免或延缓因零部件故障而导致的车辆趴窝问题和乘员舱采暖失效问题。
