## Abstract

An in-vehicle computing system and method that extracts driving intention data, driving capability data, and a driving mode data from one or more vehicle systems including an autonomous driving system. Autonomous driving information is derived from the extracted data. A message frame is created to include the autonomous driving information and sent to a V2X system.

## Claims

### Claim 1

A vehicle system comprising:
one or more systems sending and receiving one or more position data and sensor data;
an in-vehicle communication system to send and receive the one or more position data and sensor data in a Vehicle-to-Everything (V2X) system;
an in-vehicle computing system including a processor and a storage device having non-volatile memory, the storage device for storing data and instructions executable by the processor to:
extract driving intention data, driving capability data, and driving mode data from the one or more systems;
determine autonomous driving information from at least one of the extracted driving intention, driving capability, and driving mode data;
create a message frame that includes the autonomous driving information; and
send the message frame to the V2X system.

### Claim 2 (depends on 1)

The vehicle system as in claim 1, wherein driving intention data further comprises route data, driving behavior data and driving motion data.

### Claim 3 (depends on 2)

The vehicle system as in claim 2, wherein the route data further comprises a sequence of waypoints, driving behavior data further comprises a driving task and driving motion data further comprises a vehicle trajectory.

### Claim 4 (depends on 1)

The vehicle system as in claim 1, wherein driving capability data further comprises an autonomous driving level.

### Claim 5 (depends on 1)

The vehicle system as in claim 1, wherein the message frame is an extension to a Basic Safety Message.

### Claim 6 (depends on 1)

The vehicle system as in claim 1, wherein the message frame is sent upon request by a nearby vehicle in the V2X system.

### Claim 7 (depends on 1)

The vehicle system as in claim 1, wherein the message frame is sent periodically.

### Claim 8

A vehicle system comprising:
one or more components and systems sending and receiving one or more position data and sensor data from one or more vehicles in a vehicle-to-everything (V2X) system;
a communication system in communication with the V2X system;
an in-vehicle autonomous driving system in communication with the V2X system;
an intention extraction module extracting driving intention data from the in-vehicle autonomous driving system;
a driving capability extraction module extracting driving capability data from the in-vehicle autonomous driving system;
a driving mode extraction module extracting driving mode data from the in-vehicle autonomous driving system; and
a message derived from at least one of the extracted driving intention, driving capability, and driving mode data, wherein the message is sent by the communication system to the V2X system.

### Claim 9 (depends on 8)

The vehicle system of claim 8, wherein driving intention data extracted from the intention extraction module further comprises route data, driving behavior data, and driving motion data.

### Claim 10 (depends on 9)

The vehicle system of claim 9, wherein the route data further comprises a sequence of waypoints, driving behavior data further comprises a driving task and driving motion data further comprises a vehicle trajectory.
