The invention discloses an automobile, a vehicle-mounted air conditioner and a control method of a compressor of the vehicle-mounted air conditioner. The control method of the compressor of the vehicle-mounted air conditioner comprises the steps that a first rotating speed limiting value is obtained according to the current real-time power of the compressor and a preset power rotating speed limiting value curve; according to the current working mode of the vehicle-mounted air conditioner and the operation parameters of the compressor, a second rotating speed limiting value is obtained; obtaining battery cooling required power of the vehicle control unit; according to the set temperature of the vehicle-mounted air conditioner, the environment temperature data and the battery cooling required power, a third rotating speed limiting value is obtained; obtaining a fourth rotating speed limit value according to a preset noise vibration limiting strategy; screening out the lowest target rotating speed limit value from the first rotating speed limit value, the second rotating speed limit value, the third rotating speed limit value and the fourth rotating speed limit value; and controlling the compressor to operate according to the target rotating speed limit. The active limit value control function of the rotating speed of the compressor can be achieved, so that the stability of compressor control is guaranteed, and the service life of the compressor is prolonged.

    本申请公开了一种汽车、车载空调及其压缩机的控制方法,车载空调的压缩机控制方法包括:根据压缩机当前的实时功率及预设的功率转速限值曲线,获得第一转速限值;根据车载空调当前的工作模式以及压缩机的运行参数,获得第二转速限值;获取整车控制器的电池冷却需求功率;根据车载空调的设定温度、环境温度数据及电池冷却需求功率,获得第三转速限值;根据预设的噪声振动限制策略,获得第四转速限值;从第一转速限值、第二转速限值、第三转速限值以及第四转速限值中,筛选出最低的目标转速限值;根据目标转速限值控制压缩机运行。本申请可实现压缩机转速的主动限值控制功能,从而保证压缩机控制的稳定性,以及提高压缩机的使用寿命。
