LIGHT DEVICE CONTROL APPARATUS FOR VEHICLE
First Claim
1. An apparatus for controlling a vehicle light device that illuminates an area outside a vehicle, the apparatus comprising:
- an upper light intensity detection circuit configured to detect an upper light intensity of light coming from an upper side of the vehicle;
a front light intensity detection circuit configured to detect a front light intensity of light coming from a front side of the vehicle;
a determination circuit configured to determine whether the upper light intensity is equal to or less than a predetermined turn-ON threshold;
a control circuit configured to turn ON the light device when the upper light intensity is equal to or less than the turn-ON threshold;
a calculation circuit configured to calculate a light intensity ratio between the front light intensity and the upper light intensity; and
a correction circuit configured to correct the turn-ON threshold based on the light intensity ratio.

Abstract
A vehicle light device control apparatus includes a sensor unit and a control unit. The sensor unit detects an upper light intensity of light coming from an upper side of a vehicle and a front light intensity of light coming from a front side of the vehicle. The control unit determines whether the upper light intensity is equal to or less than a predetermined turn-ON threshold. The control unit turns ON a light device of the vehicle when the upper light intensity is equal to or less than the turn-ON threshold. The control unit calculates a light intensity ratio between the front light intensity and the upper light intensity and corrects the turn-ON threshold based on the light intensity ratio.
