Abstract
When it is determined that a head light is turned on, the sunset time is calculated. Thus, the frequency of calculating the sunset time is significantly decreased as compared with that of continuously calculating the sunset time, thereby reducing the processing load. Further, as compared with the case where the sunset time is calculated regardless of the time of lighting on, the calculated sunset time can evaluate the time of lighting on appropriately.
