The invention relates to the technical field of vehicles, particularly provides a vehicle-mounted air conditioner, a control method thereof and a vehicle, and aims to solve the problem that a storage battery is easily damaged when an existing vehicle-mounted air conditioner is continuously used. In order to achieve the purpose, the control method of the vehicle-mounted air conditioner comprises the following steps that the working state of the vehicle-mounted air conditioner is determined according to the state of an engine, the current of a vehicle-mounted battery, the current of the vehicle-mounted air conditioner and the sum of the currents of other working electronic elements of a vehicle. When the engine works, the vehicle-mounted air conditioner works normally. When the engine is shut down, if the current of the vehicle-mounted battery is larger than the sum of the current sum of other working electronic elements of the vehicle and the current of the vehicle-mounted air conditioner, the vehicle-mounted air conditioner works normally; and if yes, the vehicle-mounted air conditioner is shut down. The voltage of the vehicle-mounted battery does not change, and when the electric quantity is small, the current of the vehicle-mounted battery becomes small; turning off the vehicle-mounted air conditioner when the current is small; and the vehicle-mounted battery can be prevented from being damaged, so that the normal operation of the vehicle is ensured.
本发明涉及车辆技术领域,具体提供一种车载空调及其控制方法、车辆,旨在解决现有车载空调连续使用时容易损坏蓄电池的问题。为此目的,本发明的车载空调的控制方法包括如下步骤:根据发动机的状态、车载电池的电流、车载空调的电流及车辆其他工作的电子元件的电流总和,确定所述车载空调的工作状态。在当发动机工作时,则车载空调正常工作。当发动机关闭时,若车载电池的电流大于车辆其他工作的电子元件的电流总和与车载空调的电流之和,则车载空调正常工作;若小于,则车载空调关机。车载电池的电压不会变化,电量较小时,车载电池的电流会变小;电流较小时关闭车载空调;可以保证车载电池不被损坏,进而保证车辆的正常运行。
