<p>PURPOSE: A method and a system for reducing the white lead of diesel vehicle are provided to prevent white lead from being generated even in the case where the high-sulfur diesel oil is used. CONSTITUTION: A method for reducing the white lead of diesel vehicle includes a step of measuring vehicle speed (S300), a step of determining vehicle speed (S400), and a step of increasing temperature at low speed (S500). In the step of measuring vehicle speed, the speed of the vehicle is measured. In the step of determining vehicle speed, whether the measured vehicle speed is greater than or equal to the reference speed is determined. In the step of increasing temperature at low speed, in a case where the vehicle speed is below the reference speed, the rate of temperature change is controlled to be below the predetermined size when the exhaust gas post processing device increases temperature.
