Abstract

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.

First claim

What is claimed is:

1. A computing device for a vehicle exterior light control system, the computing device comprising 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, wherein 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 in or approaching an area of undulating or rolling terrain where a distance between adjacent peaks is below a predetermined minimum threshold.

2. The computing device of claim 1 wherein the relatively lower-visibility radius terrain area is a curved section of a two-way road extending around a forested area.

3. A computing device for a vehicle exterior light control system, the computing device comprising 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, wherein 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 in a location including a curved section of a two-way road extending around a base of a mountain or hill.

4. A computing device for a vehicle exterior light control system, the computing device comprising 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, wherein the one or more processors are configured to execute instructions stored in the memory to:
enable a user to designate a location as a relatively lower-visibility radius terrain area, and
automatically operate vehicle headlights responsive to a presence of the vehicle in the location.

5. A vehicle including a computing device in accordance with claim 1 .

6. A computing device configured for controlling exterior lights on a vehicle, the computing device comprising 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, wherein the one or more processors are configured to execute instructions stored in the memory to enable a user to designate a location as a “light operating location” in which one or more exterior vehicle lights are automatically operated responsive to a presence of the vehicle in the light operating location.

7. The computing device of claim 6 wherein the one or more processors are configured to execute instructions stored in the memory to enable the user to delete a previously designated “light operating location”.

8. A computing device configured for controlling exterior lights on a vehicle, the computing device comprising 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, wherein the one or more processors are configured to execute instructions stored in the memory to enable the user to designate a set of coordinates which are all located inside a parking structure as a “light operating location” in which one or more exterior vehicle lights are automatically operated responsive to a presence of the vehicle in the light operating location.

9. A method of controlling vehicle exterior lights comprising the steps of:
receiving a user-designation of a location as a “light operating location” in which one or more exterior vehicle lights are automatically operated responsive to a presence of the vehicle in the light operating location; and
automatically operating one or more exterior vehicle lights responsive to a presence of the vehicle in the user-designated light operating location.

10. The computing device of claim 6 wherein the one or more processors are configured to execute instructions stored in the memory to enable the user to designate a selected stretch of road as a “headlight operating location”.

11. The computing device of claim 6 wherein the one or more processors are configured to execute instructions stored in the memory to enable the user to designate a location as a “hazard light operating location”.

12. A vehicle including a computing device in accordance with claim 6 .
