Abstract
A passenger vehicle optical communication system includes a source vehicle including a light source and an endpoint vehicle including a camera. The source vehicle transmits a series of patterns using the light source to communicate, as one example, state information to the endpoint vehicle.
Claims20
A method of operating a vehicle communication system, comprising:
- at a first vehicle of a platoon of vehicles traveling on a roadway:
- sending first information to a second vehicle via a first line-of-sight communication system configured to communicate with the second vehicle using a first communication scheme;
- detecting, with a sensing system, a condition affecting communications between the first vehicle and the second vehicle;
- and
- in response to detecting the condition, sending second information to the second vehicle via a second line-of-sight communication system configured to communicate with the second vehicle using a second communication scheme different from the first communication scheme.

A vehicle system, comprising:
- a first vehicle comprising:
- a first line-of-sight communication system configured to communicate using a first communication scheme;
- a second line-of-sight communication system different from the first line-of-sight communication system and configured to communicate using a second communication scheme different from the first communication scheme;
- a sensing system configured to detect a condition affecting communications between the first vehicle and a second vehicle;
- and
- a vehicle controller configured to:
- send first information to the second vehicle via the first line-of-sight communication system;
- detect, with the sensing system, the condition affecting line-of-sight communications between the first vehicle and the second vehicle;
- and
- in response to detecting the condition, send second information to the second vehicle via the second line-of-sight communication system.

A vehicle configured to autonomously travel along a roadway, comprising:
- a first line-of-sight communication system configured to communicate with a trailing vehicle using a first communication scheme;
- a second line-of-sight communication system different from the first line-of-sight communication system and configured to communicate with the trailing vehicle using a second communication scheme different from the first communication scheme;
- a sensing system configured to detect a condition affecting communications between the vehicle and the trailing vehicle;
- and
- a vehicle controller configured to:
- send first information to the trailing vehicle via the first line-of-sight communication system;
- and
- in accordance with a determination that the sensing system detected the condition affecting communications between the vehicle and the trailing vehicle, send second information to the trailing vehicle via the second line-of-sight communication system.
