To restrain deterioration of a base material of an electric heating type catalyst.SOLUTION: A vehicle 110 comprises: an internal combustion engine 100; an electric heating type catalyst device 33 provided on an exhaust passage of the internal combustion engine 100, and including a conductive base material 35 generating heat by energization, and a catalyst heated via the conductive base material 35; and a control device 200. The control device 200 comprises a base material supply power control part for controlling base material supply power supplied to the conductive base material 35, and a determination part generated when moisture exists inside the catalyst device 33 in a process during which temperature of the conductive base material 35 increases, and determining whether it is in a stagnation period during which the temperature of the conductive base material 35 is partially stagnated in a predetermined temperature band. The base material supply power control part controls the base material supply power to lower power when it is determined in the stagnation period, than when it is not determined in the stagnation period.SELECTED DRAWING: Figure 1 【課題】電気加熱式触媒の基材の劣化を抑制する。【解決手段】内燃機関１００と、内燃機関１００の排気通路に設けられ、通電されることにより発熱する導電性基材３５と導電性基材３５を介して加熱される触媒とを含む電気加熱式の触媒装置３３と、制御装置２００と、を備える車両１１０であって、制御装置２００は、導電性基材３５に供給する基材供給電力を制御する基材供給電力制御部と、導電性基材３５の温度が上昇していく過程において触媒装置３３の内部に水分が存在していた場合に発生し、導電性基材３５の温度が部分的に所定温度帯域で停滞する停滞期間であるか否かを判定する判定部と、を備える。基材供給電力制御部は、停滞期間であると判定されたときは、停滞期間ではないと判定されたときと比較して、基材供給電力を低い電力に制御する。【選択図】図１
