To suppress unnecessary execution of output restriction control (PN suppressing control) to control an engine so as to suppress a discharge amount of particulate matters from the engine by having the output of the engine restricted to a predetermined output or less.SOLUTION: When warming-up of an engine has not been completed yet, output restriction control to control the engine so as to suppress a discharge amount of particulate matters from the engine is executed by having the output of the engine restricted to a predetermined output or less. In addition, after restarting from intermittent stop of the engine, the presence/absence of completion of warm-up of the engine is determined by using a top surface temperature of a piston of the engine and/or a wall surface temperature of a cylinder bore.SELECTED DRAWING: Figure 3 【課題】エンジンの出力が所定出力以下に制限されてエンジンからの粒子状物質の排出量が抑制されるようにエンジンを制御する出力制限制御（ＰＮ抑制制御）を無駄に実行するのを抑制する。【解決手段】エンジンの暖機が完了していないときには、エンジンの出力が所定出力以下に制限されてエンジンからの粒子状物質の排出量が抑制されるようにエンジンを制御する出力制限制御を実行する。そして、エンジンの間欠停止からの再始動以降には、エンジンのピストンの頂面温度および／またはシリンダボアの壁面温度を用いてエンジンの暖機の完了の有無を判定する。【選択図】図３
