Abstract
A method and system providing a vehicle condition detection means (C) for detecting the stopped and traveling state of a vehicle, and when the vehicle condition detection means (C) detects that the vehicle has stopped during operation of an exhaust gas temperature raising means (C), closing an exhaust gas throttling valve () in addition to continuing the operation of the exhaust gas temperature raising means (C), and subsequently, when the vehicle's traveling state is detected, opening the exhaust gas throttling valve () and continuing the operation of the exhaust gas temperature raising means (C). Accordingly, in terms of the regeneration of a continuous regeneration-type DPF device () capable of significantly reducing the frequency with which the driver is urged to stop the vehicle and perform forced regeneration, the exhaust gas can be efficiently maintained at a high temperature, and reliable burning of PM is possible even for driving patterns featuring frequent waiting at traffic signals in urban areas, even upon transition to the stationary idling condition during automatic traveling regeneration.
