The invention discloses a control device and method for a vehicle air conditioner, the vehicle air conditioner and a vehicle, and the device comprises an overcurrent protection switch which is arranged between a motor controller loop and an air conditioner loop; the detection unit is used for detecting the current flowing from the motor controller loop to the air conditioner loop to obtain a current detection signal under the conditions that the vehicle runs and the air conditioner runs; under the conditions that the vehicle runs and the air conditioner runs, the overcurrent protection switch is closed; the frequency converter determines whether the air conditioner loop needs overcurrent protection or not according to the current detection signal; if it is determined that the air conditioner loop needs over-current protection, an over-current protection switch is controlled to be switched off, so that the current flowing from the motor controller loop to the air conditioner loop is switched off, and an air conditioner protective tube is protected. According to the scheme, when the current flowing from the motor controller loop to the air conditioner loop is over-current, the motor controller loop and the air conditioner loop are controlled to be disconnected, so that the fuse of the air conditioner loop is prevented from being fused due to over-current, and the fuse of the air conditioner loop is protected.
本发明公开了一种车辆空调的控制装置、方法、车辆空调和车辆,该装置包括:过流保护开关,设置在电机控制器回路与空调回路之间;检测单元,在车辆行驶、且空调运行的情况下,对从电机控制器回路流向空调回路的电流进行检测,得到电流检测信号;在车辆行驶、且空调运行的情况下,过流保护开关闭合;变频器,根据电流检测信号,确定空调回路是否需要过流保护;若确定空调回路需要过流保护,则控制过流保护开关断开,以断开由电机控制器回路流向空调回路的电流,保护空调保险管。该方案,通过在从电机控制器回路流向空调回路的电流过流时,控制电机控制器回路与空调回路之间的连接断开,以避免过流使空调回路的保险管熔断,保护空调回路的保险管。
