Irradiation apparatus
First Claim
1. An irradiation apparatus comprising:
- an irradiating device configured to irradiate a periphery of a host vehicle with light in an irradiation pattern; and
a processor programmed to;
detect a relative position of a shielded object to be shielded from light emitted from the irradiation device relative to the host vehicle;
estimate an upper limit of an illumination brightness with which the shielded object is to be irradiated, based on the detected relative position of the shielded object, wherein glare is allowable to the shielded object at the upper limit of the illumination brightness or less;
estimate a lower limit of the illumination brightness, based on a brightness of a background of the shielded object, wherein a driver of the host vehicle can visually recognize the shielded object at the lower limit of the illumination brightness or more;
set the illumination brightness, based on the estimated upper limit of the illumination brightness and the estimated lower limit of the illumination brightness; and
determine an illumination control value based on the detected relative position to the host vehicle and the set illumination brightness;
control the irradiating device based on the determined control value, such that light is emitted in a predetermined irradiation pattern in which a first part of the shielded object is illuminated at the set illumination brightness and a second part of the shielded object is simultaneously illuminated at a higher illumination brightness than the set illumination brightness when seen from the host vehicle, the second part not including the first part.

Abstract
An irradiation apparatus includes a shielded object detecting unit, an illumination setting unit, an irradiating device, and an illumination controlling unit. The shielded object detecting unit detects a shielded object. Glare is allowable to the shielded object at an upper limit of illumination brightness or less. A driver can visually recognize the shielded object at an lower limit of the illumination brightness or more. The illumination setting unit sets the illumination brightness based on the upper limit and the lower limit of the illumination brightness. The illumination controlling unit controls the irradiating device such that light is emitted in a predetermined irradiation pattern in which a first part of the shielded object is illuminated at the illumination brightness set by the illumination setting unit and a second part of the shielded object is illuminated at a higher illumination brightness than that of the first part.
