A vehicle headlamp control system comprising: a plurality of light sources (52L,52U); and control means configured to control the illumination of light by the plurality of light sources (52L,52U) so as to form a predetermined illuminated area within an illumination range (PA;PA') that includes a plurality of partial areas (L1-L13,U1-U13;L1-L.13,U13,U45,U6,U78,U910,U1113), wherein the control means has a first control function in which the control means changes a difference in illuminance between partial areas (L1-L13,U1-U13;L1-L13,U13,U45,U6,U78,U910,U1113) that are contained in the illuminated area and that lie adjacent to each other before and after a swivel shift so as to shift sideways the illuminated area within the illumination range (PA;PA'), a second control function in which the control means changes a size of the illuminated area according to a driving speed of the vehicle, the control system being characterised in that the control means selects according to a driving speed of the vehicle either of a first mode and a second mode, wherein in the first mode the position of the illuminated area within the illumination range (PA;PA') is swivel shifted while maintaining the same illuminance distribution within the illuminated area as before the shift, and in the second mode the illuminance distribution within the illuminated area is changed while maintaining the position of the illuminated area within the illumination range (PA;PA'), wherein in the second mode the control means executes the control so that a total amount of currents supplied to the light sources (52L,52U) that correspond to the illumination area before the change is maintained; in that the respective luminous intensities of the plurality of light sources (52L,52U) are controlled by regulating the supplied amount of current, and in that in the second control function, the control means maintains a total amount of currents supplied to the light sources (52L,52U) that correspond to the illuminated area before the size change of the area. a plurality of light sources (52L,52U);
