摘要： PROBLEM TO BE SOLVED: To prevent a starting time from being longer because unnecessary heating operation of a structural component is executed.
SOLUTION: An ECU 12 estimates a temperature difference between a site where a temperature sensor 22 detects a temperature and a site of an exhaust control valve 7 which is frozen not guaranteeing its function, and changes a freezing determination temperature in accordance with the estimation result. Thus, it can make freezing determination approximate to the freezing condition of the site of the exhaust control valve 7 which is frozen not guaranteeing its function, therefore suppressing a starting time from being longer than normal one because the heating operation of the exhaust control valve 7 is executed with erroneous determination that there is freezing possibility in spite of no freezing possibility.
