Abstract

A first vehicle may receive at least one message from a second vehicle, the message including data provided by the second vehicle. A computing device in the first vehicle is configured to analyze the data of the at least one message to determine that the second vehicle can operate as a lead vehicle. The computing device in the first vehicle is further configured to implement at least one operation in the first vehicle according to the data from the lead vehicle.

Claims

1. A method implemented in a computer in a first vehicle, the method comprising:

receiving at least one message from a second vehicle, the message including data provided by the second vehicle;

analyzing the data in the at least one message to determine that the second vehicle can operate as a lead vehicle;

implementing at least one operation in the first vehicle according to the data from the lead vehicle.

2. The method of claim 1, wherein the data includes data collected by one or more sensors in the second vehicle.

3. The method of claim 2, wherein the first vehicle lacks sensors to provide the data collected by one or more sensors in the second vehicle.

4. The method of claim 1, wherein the data includes an indication that the second vehicle can act as a lead vehicle.

5. The method of claim 1, wherein the sensors in the second vehicle include at least one of a camera, a lidar sensor, and a radar sensor.

6. The method of claim 1, wherein the message is formatted in part according to a dedicated short range communications (DSRC) standard.

7. The method of claim 1, wherein the data included in the message includes a location of the second vehicle and a distance of the second vehicle from one of an object and a third vehicle.

8. The method of claim 7, further comprising using the location of the second vehicle and the distance of the second vehicle from one of an object and a third vehicle to determine a distance from the first vehicle of one of the object and the third vehicle.

9. The method of claim 1, wherein the at least one operation includes an autonomous operation that includes at least one of changing a speed of, adjusting a suspension of, and steering, the first vehicle.

10. The method of claim 1, wherein the at least one operation includes providing manual control of at least one function in the first vehicle, the method further comprising providing an alert via a human machine interface in the vehicle that the manual control is to be provided.

11. A system, comprising a computer in a vehicle, the computer comprising a processor and a memory, wherein the computer is configured to:

receive at least one message from a second vehicle, the message including data provided by the second vehicle;

analyze the data in the at least one message to determine that the second vehicle can operate as a lead vehicle; and

implement at least one operation in the first vehicle according to the data from the lead vehicle.

12. The system of claim 11, wherein the data includes data collected by one or more sensors in the second vehicle.

13. The system of claim 12, wherein the first vehicle lacks sensors to provide the data collected by one or more sensors in the second vehicle.

14. The system of claim 12, wherein the data includes an indication that the second vehicle can act as a lead vehicle.

15. The system of claim 12, wherein the sensors in the second vehicle include at least one of a camera, a lidar sensor, and a radar sensor.

16. The system of claim 12, wherein the message is formatted in part according to a dedicated short range communications (DSRC) standard.

17. The system of claim 12, wherein the data included in the message includes a location of the second vehicle and a distance of the second vehicle from at least one of an object and a third vehicle.

18. The system of claim 17, further comprising using the location of the second vehicle and the distance of the second vehicle from one of an object and a third vehicle to determine a distance from the first vehicle of one of the object and the third vehicle.

19. The system of claim 12, wherein the at least one operation includes an autonomous operation that includes at least one of changing a speed of, adjusting a suspension of, and steering the first vehicle.

20. The system of claim 12, wherein the at least one operation includes providing manual control of at least one function in the first vehicle, the method further comprising providing an alert via a human machine interface in the vehicle that the manual control is to be provided.
