<p><P>PROBLEM TO BE SOLVED: To provide a limp home control device capable of minimizing the deterioration in drivability, by preventing an evil by progress of an excessive deposit by restraining a PM discharge quantity of an internal combustion engine when a DPF is excessively deposited. <P>SOLUTION: When determining that the DPF is excessively deposited, after prohibiting forced regeneration for incinerating and removing PM, the upper limit on target average effective pressure Pe of an engine operation area (an area surrounded by a broken line) is restricted to the low area side for avoiding a PM increasing area (an area surrounded by hatching). The upper limit on an engine speed Ne is switched to a control map for a limp home mode expanded up to the high area side. Thus, the PM discharge quantity is restrained by reducing a fuel injection quantity of an engine, and the gear ratio R of a CVT is increased, and request driving force is secured by enhancing the engine speed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
