System for adjusting brightness of vehicle lighting, vehicle having the same, and control method thereof
First Claim
1. A system for adjusting brightness of vehicle lighting comprising:
- a first lighting unit provided in a cluster;
a luminance input configured to receive an input of a target luminance of the first lighting unit,a second lighting unit provided in a center fascia;
a recognizer configured to recognize ON and OFF operations of a light provided in an exterior of vehicle;
a detector configured to detect an external illuminance; and
a controller configured to adjust a luminance of the first and second lighting units based on operation information of the light and the external illuminance,wherein the controller adjusts the luminance of the first and second lighting units to a maximum luminance when the light is in an ON operation state and the detected external illuminance is greater than or equal to a reference illuminance,adjusts the luminance of the first and second lighting units to the maximum luminance when the light is in an OFF operation state, andadjusts the luminance of the first and second lighting units to the target luminance of the first lighting unit when the light is in the ON operation state and the detected external illuminance is less than the reference illuminance.

Abstract
A vehicle having a light in an exterior and a cluster and a center fascia in an interior includes a first lighting unit provided in the cluster, a second lighting unit provided in the center fascia, a recognizer configured to recognize ON and OFF operations of the light, a detector configured to detect illuminance, and a controller configured to adjust luminance of the first and second lighting units based on operation information of the light and the illuminance. A structure of the lighting unit within the center fascia may be simplified by adjusting brightness of the lighting unit within the center fascia in the controller configured to control the lighting unit of the cluster and therefore manufacturing cost may be reduced.

4. A vehicle having a system for adjusting brightness of vehicle lighting, comprising:
-
a detector configured to detect an external illuminance; a cluster having a first lighting unit and configured to receive ON and OFF operation information of a light provided in an exterior of vehicle and the external illuminance, to determine a luminance of the first lighting unit based on the received light operation information and the external illuminance, to control luminance of the first lighting unit to the determined luminance, and to output an adjustment signal corresponding to the determined luminance; a luminance input configured to receive an input of a target luminance of the first lighting unit; and a second lighting unit configured to adjust the luminance of the second lighting unit based on the adjustment signal output from the cluster, wherein the cluster adjusts the luminance of the first lighting unit to the target luminance when the light is in an ON operation state and the detected external illuminance is less than a reference illuminance. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

13. A control method for lighting device of a vehicle, comprising steps of:
-
receiving operation information of a light provided in an exterior of the vehicle and a detected external illuminance; adjusting a luminance of a first lighting unit provided in a cluster based on the operation information of the light and the detected external illuminance; and outputting an adjustment signal corresponding to the adjusted luminance of the first lighting unit to a second lighting unit provided in a center fascia; wherein the step of adjusting the luminance of the first lighting unit includes steps of;
receiving an input of a target luminance; and
adjusting the luminance of the first lighting unit to the target luminance when the light is in an ON operation state and the detected external illuminance is less than a reference illuminance. - View Dependent Claims (14, 15, 16, 17)
