Patent ID: 7082754

Claim:
A control device for a regeneration mechanism of a filter which traps particulate matter contained in an exhaust gas of a diesel engine for a vehicle, comprising: a first sensor which detects whether or not the diesel engine is performing an idling operation; a second sensor which detects a temperature of the filter; and a programmable controller programmed to: calculate, on the basis of an output of the first sensor, a first parameter indicating a frequency with which the diesel engine performs an idling operation over a predetermined time period up to the present; calculate, on the basis of an output of the second sensor, a second parameter indicating a temperature environment of the filter over a predetermined time period up to the present; determine whether or not a complete regeneration of the filter is possible on the basis of the first parameter and second parameter; and control the regeneration mechanism to perform complete regeneration of the filter, when the complete regeneration of the filter is determined to be possible.
