An engine controller ( 20 ) controls regeneration of a diesel particulate filter ( 11 ) deployed along an exhaust passage ( 3 ) of a vehicle diesel engine ( 9 ). Regeneration terminates in response to a terminating request based on running conditions of the diesel engine ( 1 ). When the regeneration elapsed time at the time of termination is shorter than a reference duration, the engine controller ( 20 ) adds a time corresponding to a deviation of the regeneration elapsed time from the reference duration to the reference duration for the next regeneration of the DPF ( 11 ), thereby completely removing particulate matter accumulated in and around an inlet ( 18 ) of the filter ( 11 ).
