When the automatic stop condition is satisfied, fuel injection is stopped and the internal combustion engine (1) is automatically stopped. When there is a restart request during a reduction in the rotational speed of the internal combustion engine by the automatic stop, if the rotational speed of the internal combustion engine is greater than or equal to a recoverable combustion rotational speed threshold value (R1) at which restart can be performed only by fuel injection, the internal combustion engine (1) is started by recovering the fuel injection. When the rotational speed of the internal combustion engine is less than the recoverable combustion rotational speed threshold value (R1), the internal combustion engine (1) is started by the starting motor (2). When there is a restart request while the brake is on, the internal combustion engine (1) is started by rotating the internal combustion engine by the starting motor (2) without performing restart by fuel injection. 如果自动停止条件成立，则停止燃料喷射而使得内燃机(1)自动停止。在基于自动停
