Abstract
An exhaust pipe for a diesel engine is connected to a diesel particulate defuser ('DPD'). To automatically regenerate the DPD, an exhaust gas temperature is detected, a deviation of the detected exhaust gas temperature from a target regeneration temperature is evaluated, and an amount of post injection is controlled through PID control according to the deviation. When, during the automatic regeneration with a vehicle running, an exhaust brake valve is closed, the post injection is interrupted. While the exhaust brake is being closed, an operation of an integral control term is continued with the PID control, and when the exhaust brake valve is opened, the integral control term operated without interruption is used as an initial amount of operation.
