AMP (2-Amino-2-Methyl-1, 3-Propanediol) does not release the absorbed heat during temperature drop but releases it during temperature rise. Also, AMP keeps a solid state upon the heat release. The heat storage material which is the aggregate of AMP is arranged to exchange heat with the subject for warm-up. In the warm-up acceleration control, it is judged whether or not there is a request for warm-up to the subject for warm-up (step S). If it is judged that there is the request for warm-up, it is judged whether or not the radiation condition of the heat storage material is satisfied (step S). If it is judged that the radiation condition is satisfied, the heater is started to operate (step S). By operating the heater, the heat storage material is directly or indirectly heated.

An estimated electromotive voltage is calculated on the basis of the temperatures at three points that are defected or estimated. A malfunction of the power generator is detected when the absolute value of the difference between the estimated electromotive voltage and an actual electromotive voltage is greater than or equal to a threshold value.

The present invention relates to a vehicular air cleaner. It is an object to provide a DOR system which can utilize a purifying function of an ozone purifying element containing an activated carbon for a long period of time. As shown in Aand Aof FIG., in the activated carbon at an initial state, an ozone purification rate is almost the same as the same wind velocity even when a temperature condition is different, even though the ozone purification rate is changed when the wind velocity is changed. After the endurance test, the ozone purification rate is increased even at the same wind velocity when the temperature becomes high as shown in Band Bof FIG.. Thus, the temperature condition difference affects the ozone purification rate more as the deterioration o the activated carbon continues.
