The invention discloses a protection control method and device for a vehicle-mounted compressor, a vehicle-mounted air conditioner and a vehicle. The method comprises the steps that in the process that a power converter is controlled to drive the compressor to work, the temperature of a switching tube in the power converter, the current of the compressor and the rotating speed of the compressor are obtained; determining a current protection limit value and a current protection recovery value of the compressor based on the temperature; and performing overcurrent protection control on the compressor according to the current protection limit value, the current protection recovery value, the current and the rotating speed. According to the method, the overcurrent protection function of the compressor can be more comprehensive so as to be suitable for various complex environments, and therefore the safety of the vehicle-mounted compressor is improved.
