PURPOSE: A maximum power point tracking (MPPT) control method for a mobile photovoltaic power generation module is provided to increase power generation efficiency by enabling the voltage at a maximum power point to be an instructed voltage. CONSTITUTION: A present output current of a power generation module is measured (S1100). An output current variation is calculated by comparing the present output current and a previous output current measured previously (S1400). If the output current variation is less than a threshold current variation, the output voltage of the power generation module is increased as much as a multiple voltage variation which is bigger than a unit voltage variation by a fixed multiple, and the process returns to the output current measurement step (S1420).
