LIGHT DISTRIBUTION CONTROL DEVICE, VEHICLE LIGHT SYSTEM, AND LIGHT DISTRIBUTION CONTROL METHOD

A light distribution control device (6), if a first upper limit number (N1) ≥ the number of near-distance targets (T1), controls a lamp (2) to irradiate the near-distance targets with light having illuminance according to attributes of the near-distance targets; if a remaining number (M) ≥ the number of long-distance targets (T2), controls the lamp (2) to irradiate the long-distance targets with light having illuminance according to attributes of the long-distance targets; if N1 < Tl, controls the lamp (2) to form a light distribution pattern (PTN, PTN1) that does not depend on the near-distance targets and the long-distance targets; and, if M < T2, controls the lamp (2) to form a light distribution pattern (PTN, PTN2) that does not depend on the long-distance targets.
