摘要：<p>There is provided a method of controlling an engine system having an internal combustion engine, a supercharger arranged in an intake air passage of said internal combustion engine and a motor capable of driving the supercharger. The method comprises, driving the motor to operate the supercharger to boost airflow inducted into the internal combustion engine when the internal combustion engine is in operation. The method further comprises driving the motor to determine a state of the supercharger when the internal combustion engine is stopped and indicating the determined state of the supercharger. According to the method, by driving the motor of the supercharger to detect a state of the supercharger when the internal combustion engine is stopped, the state of the supercharger can be more accurately detected because the condition is most stable.</p>
