PURPOSE: A smoke reducing method of a diesel vehicle is provided to prevent the stop of a starting and the deterioration of the fuel efficiency and to reduce the effect from the pressure change according to an acceleration and a reduction by using a similarity equation. CONSTITUTION: In starting a vehicle, every variable is initialized(S100). The regeneration of diesel particulate filter is checked(S110). An injection control signal is outputted(S155) by deciding an injecting area(S140,S145) after following a driving condition. The stop of an engine according to the pressure change of the diesel particulate filter is prevented(S150,S160). Thereby, the stop of the engine during a driving and the deterioration of the fuel efficiency are prevented.
