Abstract

A vehicle air conditioner has a refrigeration cycle system including a compressor. The rotational frequency of the compressor is variably controlled, and the compressor is prevented from being operated within a resonating rotational frequency range of the compressor in which the vibration frequency of the compressor and the natural frequency of a steering device resonate with each other. When the vehicle performs automated driving, the compressor is also allowed to operate within the resonating rotational frequency range.
