Abstract: A vehicle control system includes a first control apparatus that controls a first lamp mounted in a vehicle and a second control apparatus that controls a second lamp mounted in the vehicle. The first control apparatus starts light-on/off control of the first lamp under a condition that a light-on/off command is inputted, turns on/off the first lamp such that a light quantity of the first lamp is gradually changed over a first transition time from the start of light-on/off control to when the light quantity of the first lamp reaches a target and light-on/off is completed, and inputs an auxiliary light-on/off command to the second control apparatus. The second control apparatus starts light-on/off control of the second lamp under a condition that the auxiliary light-on/off command is inputted, and turns on/off the second lamp such that a light quantity of the second lamp is gradually changed over a second transition time from the start of light-on/off control to when the light quantity of the second lamp reaches a target and light-on/off is completed. The first transition time is longer than the second transition time by an amount of time corresponding to a time lag from the start of light-on/off control of the first lamp to the start of light-on/off control of the second lamp.

Abstract: A vehicular headlamp apparatus includes: 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 which include, at least, a high beam and a low beam; detecting means for detecting a forward vehicle present in front of the vehicle; controlling means for controlling the light distribution pattern switching means based on a detection result of the detecting means; and turning radius acquiring means for acquiring a turning radius of the own vehicle during running. Moreover, 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.

Abstract: In a headlamp light distribution control device, a light source configured by a pair of lamps mounted in a forward vehicle is extracted from an image of the forward vehicle if a distance to the forward vehicle is less than a predetermined value, and the number of the extracted light sources is judged. When the number of the extracted light sources is two, an irradiation direction of a headlamp is controlled such that a shielded area is set in an irradiation area to prevent an area including the lamp of the forward vehicle from being irradiated. When the number of the extracted light sources is one, the irradiation direction is controlled such that a shielded area is set in the irradiation area to have a margin in right and left directions larger than the shielded area set when the number of the extracted light sources is two.

Abstract: Speed of a vehicle is acquired from a speed detecting device, and then a beam switching threshold, according to the acquired speed, of an irradiation direction of a headlight is initially set. When the number of appearance (i.e. frequency of appearance) of a light source in a predetermined time detected by a light source detection means have become the beam switching threshold or more, the headlight is switched to a low beam. When a predetermined time (beam switching prohibition time Tp) has been passed after the irradiation direction of a headlight was switched to the low beam, the irradiation direction of the headlight is switched to a high beam.

Abstract: A control apparatus, which controls a headlight unit, repeatedly performs a process of measuring brightness ahead of the own vehicle using a luminance sensor. For example, when a curved road region is present ahead of the own vehicle, measurement is made of the brightness of a road surface or a guardrail of a specified region (region to which light from a headlight unit of a forward vehicle is emitted) in the road region. Then, a variation (Δ) in a measurement value of the brightness from a previous measurement value is calculated. When the variation (Δ) is equal to or more than a threshold TH, a vehicle yet to emerge is predicted to emerge in a forward view of the own vehicle to thereby switch a lighting mode for the light emitted from the headlight unit to another mode so that the emergence area is darkened.
