<P>PROBLEM TO BE SOLVED: To provide a regeneration control method for an emission control device in a diesel hybrid vehicle capable of promoting the regeneration of PM of the emission control device by increasing the chance of the regeneration of PM of the emission control device also when an EV is running except when an engine is running. <P>SOLUTION: When the engine is running and EV running conditions are established, low temperature combustion control as the temperature raising control of a PM collecting device is performed (steps S10 affirmation, step S20), and then the engine is stopped and PM is regenerated during the running of an EV (step S30, step S50, step S90). When the overheating of a catalyst must be avoided (step S40 affirmation) or air must be supplied to the catalyst (step S60 affirmation) during the running of the EV, a clutch is engaged to supply air to the PM collecting device to cool the catalyst so as to avoid overheating (step S100), and also oxygen is supplied to the catalyst in the shortage state of oxygen to promote oxidation reaction so as to promote the regeneration of PM (step S70). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
