A headlight control data generation device that generates headlight control data of a vehicle including a headlight includes an electronic control unit. The electronic control unit sequentially acquires, when a manual mode is selected, set data including a detection value of an illuminance around the vehicle, and ON and OFF data indicating that the headlight is in an ON state or in an OFF state at the time of sampling of the detection value, and generates the headlight control data based on the acquired set data. The headlight control data includes data regarding information on a probability of the headlight being in an ON state.

In an optical sensor, a detecting part includes detecting elements, and a light-shielding portion providing directional characteristics of light to the detecting elements such that the detecting elements indicate different intensities of light received in a specified direction. A signal processing part has an adjustment value for processing detection signals. The adjustment value is set as follows. Based on information of an inclination angle of a window glass of a vehicle to which the detecting part is attached, from the detecting elements, a detecting element having a directional characteristic of light suitable for the inclination angle is selected. The adjustment value is then set so as to coincide a signal value of a detection signal of the selected detecting element with a target value, when the detecting part is irradiated with light in a predetermined direction in a state where the detecting part is inclined at the inclination angle.

A position lighting device is configured to be installed on a vehicle and configured to radiate a beam such that people outside the vehicle can recognize the vehicle. A lighting unit is configured to radiate a beam to a ceiling part or a side wall part of a tunnel-like structure which has at least a floor part, the ceiling part, and the side wall part. A position recognizing unit is configured to recognize that the vehicle is positioned in the tunnel-like structure. A radiation control unit is configured to control the lighting unit to radiate the beam if the position recognizing unit recognizes that the vehicle is positioned in the tunnel-like structure.

A method and apparatus for providing navigation services including illumination data. A request for a route is received with one or more preferences related to illumination for the route. One or more road segments that have illumination road attributes that correspond to the one or more preferences are selected. The illumination road attributes are calculated as a function of high beam frequency for the one or more road segments. The route is generated including the one or more road segments. The route is provided with the illumination road attributes.

A lamp for a vehicle includes: a lamp module configured to project a light having a beam pattern onto a road surface; at least one processor; and a computer-readable medium coupled to the at least one processor having stored thereon instructions which, when executed by the at least one processor, causes the at least one processor to perform operations comprising: obtaining vehicle driving information associated with driving of the vehicle; determining, based on vehicle driving information, a light adjustment region;

and based on the determination of the light adjustment region, performing a gradual control of light projected to the light adjustment region, the gradual control of light configured to progressively change a brightness of light in the light adjustment region.
