PROBLEM TO BE SOLVED: To set the most-suitable electric fan operating time in the case that an ignition switch is turned off during idle stopping state.SOLUTION: In the case that a time in which a time that an electric fan is operated ranging from starting of an idle stopping state to a turning-off of an ignition switch is subtracted from the first operating time is applied as a reference time and a time coinciding with the reference time is present within a set time, an electric fan control device selects the time coinciding with the reference time as the second operating time and in turn in the case that the time coinciding with the reference time is not present within the set time, the electric fan control device selects, as the second operating time, a time in which a thermal influence accepted by the first component under thermal atmosphere dispersed in an engine room and a time in which a thermal influence accepted by the second component become within an allowable range in reference to a set time (t1) that is most nearest to the reference time in a time shorter than the reference time and a set time (t2) that is most nearest to the reference time in a time longer than the reference time. |
