    摘要: A headlight device includes a light source unit to emit first light, a first optical unit to change a light distribution pattern of incident first light, a light-reception unit to detect incident second light, a second optical unit to project the light distribution pattern in a predetermined projection direction and receive incident light traveling in a direction opposite to the projection direction, a third optical unit to emit the first light toward the second optical unit and emit incident light that has passed through the second optical unit as second light toward the light-reception unit, and a fourth optical unit to focus the second light and direct toward the light-reception unit. The light distribution pattern is controlled based on a detection result of second light in the light-reception unit.

    摘要: A vehicular lamp system includes a light distribution control device that controls a first lamp unit and a second lamp unit. The light distribution control device forms a combined high-illuminance pattern in a region where no target is present. Meanwhile, the light distribution control device forms a combined shading pattern in regard to a forward vehicle. Furthermore, in regard to a specific target, the light distribution control device controls the first lamp unit so as to form an illuminance fixed pattern, controls the second lamp unit so as to form an illuminance fixed pattern or to form an illuminance adjusted pattern, and forms a combined mid-illuminance pattern by superposing the light distribution patterns that the first lamp unit and the second lamp unit form.

    摘要: To accurately identify positions of preceding vehicles. A vehicle position identification apparatus having a controller, where the controller (a) acquires position data of each forward vehicle, each position data including a left side position and a right side position of each forward vehicle, and (b) for each position data at a first time and a second time, associates the left side position with a first axis and the right side position with a second axis and obtains a distance between each of the position data on coordinates, or obtains the amount of change in the left side position along the first axis and the amount of change in the right side position along the second axis, and based on the distance or each of the amount of change, identifies a correspondence relationship between each of the position data and each forward vehicle and generates data which indicates the correspondence relationship.

    摘要: A vehicle includes a vehicle feature predesignated as limited-use and may determine that a conditional parameter for enabling the vehicle feature has been met, based at least on a present vehicle state. The vehicle engages the vehicle feature responsive to the present vehicle state meeting the conditional use parameter and monitors changes to the present vehicle state. Also, the vehicle automatically controls the feature in accordance with changes to the present vehicle state, to adaptively control the vehicle feature reactive to the changes to the present vehicle state relative to the conditional use parameter.

    摘要: A vehicle lighting device includes: a low-beam irradiation part which illuminates a lower irradiation region on a forward lower side of a vehicle; a high-beam irradiation part which illuminates an upper irradiation region on an upper side and more to a central side in a vehicle-width direction than the lower irradiation region; and a pattern irradiation part which irradiates irradiation light on a lateral irradiation region that is a travel path side of the vehicle in an irradiation pattern in which a bright region and a dark region are alternately repeated, in which the pattern irradiation part irradiates irradiation light in a predetermined first mode on an upper pattern irradiation region that is an upper side of the lateral irradiation region, and irradiates irradiation light in a second mode different from the first mode in a lower pattern irradiation region that is a lower side of the lateral irradiation region.
