Claim:
1. A vehicular headlamp apparatus comprising: a headlamp that illuminates ahead of a vehicle; light distribution pattern switching means for switching light distribution pattern of the headlamp between a plurality of light distribution patterns, the plurality of light distribution patterns including, at least, a high beam and a low beam; detecting means for detecting a forward vehicle present in front of the vehicle; and controlling means for controlling the light distribution pattern switching means based on a detection result of the detecting means, wherein the vehicular headlamp apparatus further comprises turning radius acquiring means for acquiring a turning radius of the own vehicle during running, and when the turning radius of the own vehicle acquired by the turning radius acquiring means is less than a predetermined value, the controlling means inhibits the switching of the light distribution pattern of the headlamp to a higher side, characterized in that the plurality of light distribution patterns include the high beam, the low beam and an intermediate high beam between the high beam and the low beam, and the predetermined value comprises a first predetermined value used for determination of the inhibition of the switching to the intermediate high beam and a second predetermined value used for determination of the inhibition of the switching to the high beam, the second predetermined value being different from the first predetermined value.
