To make it possible to accurately determine that dew condensation of a dust sensor is dissolved when dew condensation of the dust sensor is dissolved.SOLUTION: Whether or not dew condensation occurs in a dust sensor 32 (S80) is determined, and when it is determined that dew condensation occurs in the dust sensor 32, an amount of dew condensation, which occurs in the dust sensor 32, is estimated by use of at least one of a temperature and a humidity of air around the dust sensor 32 (S110), and based on the estimated amount of dew condensation, a dew condensation dissolution time until dew condensation, which occurs in the dust sensor 32, is dissolved is specified (S130).SELECTED DRAWING: Figure 5
【課題】埃センサの結露が解消した際に、埃センサの結露が解消したことを正確に判定できるようにする。【解決手段】埃センサ32に結露が発生したか否かを判定し(S80)、埃センサ32に結露が発生したと判定された場合、埃センサ32の周囲の空気の温度および湿度の少なくとも一方を用いて埃センサ32に発生した結露量を推定し(S110)、推定した結露量に基づいて埃センサ32に発生した結露が解消されるまでの結露解消時間を特定する(S130)。【選択図】図5
