While an own vehicle is traveling through the tunnel, a lighting ECU detects a side-wall position direction indicating a direction of a side wall of a tunnel T, which is adjacent to a lane in which the own vehicle is traveling, with respect to the own vehicle. The lighting ECU turns ON one of cornering lights respectively provided on a left side and a right side of the own vehicle, which is provided on the side-wall position direction.

A computing device for a vehicle exterior light control system is described. The computing device includes one or more processors for controlling operation of the computing device, and a memory for storing data and program instructions usable by the one or more processors. The one or more processors are configured to execute instructions stored in the memory to automatically operate vehicle headlights responsive to a location of the vehicle.

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.

Disclosed are an intelligent control method and system for automobile headlights, which is used for improving traveling safety and comfort, and meanwhile solving the problem that monitoring the control result is not provided by existing automobile control systems. The intelligent control system for automobile headlights can control turning on and off of the automobile headlights automatically according to the changes of ambient light intensity, and switching between high/low beam lights can be automatically realized when automobiles meet at night, and meanwhile a self-diagnostic function is provided. Whether the control system for automobile headlights operates in an automatic mode or a manual mode, the operating status of the headlights can be monitored by the self-diagnostic function of the system and a fault point can be located accurately, which is output by means of a fault display lamp or a fault code. It is convenient for maintenance personnel to repair or monitor the illumination condition of an automobile on the basis of the automobile operational system of the automobile network, and for a driver or relevant service staffs to know the operating status of automobile headlights in real time.

A method and apparatus for mapping road illumination. A server receives high beam data. The server receives roadway conditions. The server calculates a high beam frequency for a road segment based on the high beam data and the roadway conditions. The server calculates road illumination from the high beam frequency. The server augments a geographic database with road illumination information.

A method of operating a vehicle includes receiving a radio frequency signal and determining that the radio frequency signal has at least one characteristic indicative of the vehicle entering a tunnel. A setting of a vehicle system is automatically modified in response to the determining step.
