Abstract
The invention relates to a control method for an internal combustion engine system, capable of preventing an internal combustion engine in a state after being automatically stopped, from falling into an unrestartable state. Upon satisfaction of a given automatic stop condition, the enginebeing running is automatically stopped (Step). A value of current Iflowing out of a starter batteryis compared with a given current value I, in an automatically stopped state of the engine(Step S) to diagnosis a discharging status of the starter battery. If a result of the diagnosis indicates that the value of current Iflowing out of the starter batteryis greater than the given current value I, it is determined that a post-attached load is detected, and the engineis restarted irrespective of the satisfaction or non-satisfaction of a given restart condition.
