Zusammenfassung:An activation control device includes: a main CPU to be activated at a time based on a set value of an interrupt timer or when an activation factor occurs; and a sub-CPU. The main CPU adjusts the set value such that a total active time of the main CPU per predetermined time approaches a target active time, and based on a determination that adjustment of the set value alone cannot make the total active time approach the target active time, controls not to activate the main CPU for at least a part of the activation factors.
