<p><P>PROBLEM TO BE SOLVED: To more accurately determine whether an exhaust supply apparatus is normal or not. <P>SOLUTION: When determining whether an EGR system is normal or not, EGR system inspection is executed (S190, S240) accompanied by execution of control for inspection controlling an engine so that the engine is operated in a prescribed load operation state outputting power Pech from the engine (S140, S180, S230). Consequently, change of operation conditions of the engine during EGR system inspection can be inhibited and the EGR system inspection can be more accurately executed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
