Communicating position information between vehicles
First Claim
1. A method for communicating position information between vehicles, the method comprising:
- broadcasting from a first vehicle a message using a wireless communication pathway, the message describing a position of the first vehicle, a speed of the first vehicle, a direction in which the first vehicle is traveling and status information of the first vehicle wherein the status information indicates a status of a system in the first vehicle or indicates an abrupt change in speed or direction of the first vehicle;
receiving the message at a second vehicle;
determining a position of the second vehicle, a speed of the second vehicle, and a direction in which the second vehicle is traveling; and
comparing the position of the first vehicle, the speed of the first vehicle, and the direction in which the first vehicle is traveling with the position of the second vehicle, the speed of the second vehicle, and the direction in which the second vehicle is traveling to determine whether an action is required by the second vehicle.

Abstract
Wireless communication between vehicles may permit position information about one vehicle to be communicated directly to another vehicle. Such an information exchange between vehicles may increase the awareness of an operator of a vehicle to other vehicles in the surrounding environment and may help a vehicle operator operate the vehicle more safely. Vehicles may share through the use of wireless communications position, direction, speed, or other information, such as the deployment of safety devices or the presence of particular types of vehicles (e.g., an emergency vehicle or school bus). The vehicle that receives a wireless communication compares the position, direction, and speed of incoming information from another vehicle to the vehicle'"'"'s own speed, direction, and position to determine whether action is required. The action taken by the vehicle may include providing general or specific warnings to the operator of the vehicle or, in some cases, taking direct action, such as turning off cruise control, applying brakes, or deploying traction control.

11. A vehicle that processes position information received from other vehicles, the vehicle comprising a processor connected to a storage device and connected to one or more input/output devices, with the processor being configured to:
-
receive from a second vehicle a message sent using a wireless communication pathway, the message describing a position of the second vehicle, a speed of the second vehicle, a direction in which the second vehicle is traveling and status information of the first vehicle wherein the status information of the first vehicle indicates a status of a system in the first vehicle or indicates an abrupt change in speed or direction of the first vehicle;
determine a position of the vehicle, a speed of the vehicle, and a direction in which the vehicle is traveling; and
compare the position, speed, and travel direction of the vehicle with the position, speed, and travel direction of the second vehicle to determine whether an action is required by the second vehicle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for communicating position information between vehicles, the method comprising:
-
broadcasting from a first vehicle a message using a wireless communication pathway, the message describing a position of the first vehicle, a speed of the first vehicle, a direction in which the first vehicle is traveling, and a type of the first vehicle wherein the type of the first vehicle is an approaching emergency vehicle or a bus that is loading or unloading passengers;
receiving the message at a second vehicle;
determining a position of the second vehicle, a speed of the second vehicle, and a direction in which the second vehicle is traveling; and
comparing the position of the first vehicle, the speed of the first vehicle, the direction in which the first vehicle is traveling, and the type of the first vehicle with the position of the second vehicle, the speed of the second vehicle, and the direction in which the second vehicle is traveling to determine whether an action is required by the second vehicle. - View Dependent Claims (23, 24, 25)
