1. A headlamp control system comprising:
a headlamp configured to emit a low beam toward a forward direction of a vehicle;
cornering lamps each configured to illuminate a corresponding one of left and right cornering areas of the vehicle; and
a control part configured to control the headlamp,
wherein
the control part controls the headlamp in a manner depending on an operation situation of the vehicle,
the headlamp is switchable between a first low beam distribution state and a second low beam distribution state,
the headlamp is configured to, in the first low beam distribution state, illuminate a low area straight ahead of the vehicle, and in the second low beam distribution state, illuminate at least one of: a width-direction intermediate portion of the low area, one width-direction end portion of the low area, and the other width-direction end portion of the low area, even brighter than the first low beam distribution state,
the headlamp is further configured to, in the second low beam distribution state, when illuminating at least one of the one width-direction end portion of the low area and the other width-direction end portion of the low area even brighter than the first low beam distribution state, illuminate an area extending further than a side of the low area outward in a width direction corresponding to the at least one of the one width-direction end portion of the low area and the other width-direction end portion of the low area, thereby to illuminate an area ahead of a corresponding one of the cornering areas, and
the control part is further configured to, when an operation on a steering wheel or on turn signal lamps is performed, control the headlamp to illuminate, of the left and right cornering areas, one that corresponds to the operation and to illuminate, in the second low beam distribution state, of the one width-direction end portion and the other width-direction end portion, one that corresponds to the operation further than the first low beam distribution state outward in a corresponding width direction.
