Abstract
An automatic lighting device includes an illuminance detector for detecting an external illuminance around a vehicle, a light controller for turning on/off a vehicular light, a driver's characteristics detector for acquiring information about driver's physical characteristics, and a threshold setting element for setting the illuminance threshold in accordance with the driver's physical characteristics. The controller turns on the light when the external illuminance is not more than the illuminance threshold.
Claims17
An automatic lighting device comprising:
- an illuminance detector for detecting an external illuminance around a vehicle;
- a light controller for turning on/off a vehicular light to illuminate an outside of the vehicle, wherein the light controller turns on the vehicular light when the external illuminance is not more than an illuminance threshold;
- a driver's characteristics detector for acquiring information about a driver's physical characteristics;
- and
- a threshold setting element for setting the illuminance threshold in accordance with the driver's physical characteristics.
A method for controlling a vehicular light to illuminate an outside of a vehicle, the method comprising:
- detecting an external illuminance around a vehicle;
- turning on the vehicular light when the external illuminance is not more than an illuminance threshold;
- acquiring information about a driver's physical characteristics;
- and
- setting the illuminance threshold in accordance with the driver's physical characteristics.
An automatic lighting device comprising:
- an illuminance detector for detecting an external illuminance around a vehicle;
- a light controller for turning an exterior light of the vehicle on when the exterior illuminance is below a specified threshold;
- a driver's characteristic detector for acquiring information about a driver's physical characteristic;
- and
- a threshold setting element for setting the specified threshold based on the driver's physical characteristic.
