The invention discloses a vehicle thermal management system and a control method thereof and a vehicle, and the device comprises a sampling device which is used for sampling the battery detection actual temperature of the vehicle, sampling the passenger compartment detection actual temperature of the vehicle, and sampling the motor detection actual temperature of the vehicle; the control device is used for controlling opening and closing of the compressor according to at least one of the actual temperature detected by a battery of the vehicle, the actual temperature detected by a passenger compartment of the vehicle and the actual temperature detected by a motor of the vehicle, and/or controlling opening and closing of corresponding valves in the valve device so as to control the flow direction of the refrigerant. The heat exchange requirements of the battery and the passenger compartment in the vehicle are met at the same time. According to the scheme, the flow direction of the refrigerant is controlled according to the detected actual temperature of the battery, the passenger compartment and the motor, and the heating or cooling requirements of the battery and the passenger compartment can be met at the same time in ultralow-temperature weather or ultrahigh-temperature weather.
本发明公开了一种车辆热管理系统及其控制方法和车辆,该装置包括:采样装置,用于采样车辆的电池检测实际温度,采样车辆的乘员舱检测实际温度,以及采样车辆的电机检测实际温度;控制装置,用于根据车辆的电池检测实际温度、车辆的乘员舱检测实际温度、以及车辆的电机检测实际温度中的至少之一,控制压缩机的启闭,和/或控制阀件装置中相应阀件的启闭以控制冷媒的流向,实现同时满足车辆中电池和乘员舱的换热需求。该方案,通过根据电池、乘员舱和电机的检测实际温度控制制冷剂流向,在超低温天气或超高温天气下也能同时满足电池和乘员舱的制热或制冷的需求。
