Abstract

A method for generating a message including vehicle operating parameters. The method includes the following: measuring operating parameters of an unequipped vehicle using monitoring equipment present on an equipped vehicle that is proximate to the unequipped vehicle; generating at the equipped vehicle a message including the measured operating parameters of the unequipped vehicle; and transmitting from the equipped vehicle to surrounding vehicles the message including the measured operating parameters of the unequipped vehicle to inform surrounding vehicles of the operating parameters of the unequipped vehicle

Claims

1. A method for generating a message including vehicle operating parameters comprising:

measuring operating parameters of an unequipped vehicle using monitoring equipment present on an equipped vehicle that is proximate to the unequipped vehicle;

generating at the equipped vehicle a message including the measured operating parameters of the unequipped vehicle; and

transmitting from the equipped vehicle to surrounding vehicles the message including the measured operating parameters of the unequipped vehicle to inform surrounding vehicles of the operating parameters of the unequipped vehicle.

2. The method of claim 1, wherein:

the message is a basic safety message (BSM);

the equipped vehicle and the surrounding vehicles are equipped with dedicated short range communications (DSRC) operable to send and receive BSMs; and

the unequipped vehicle is not equipped with functioning DSRC.

3. The method of claim 1, further comprising measuring the operating parameters of the unequipped vehicle relative to the equipped vehicle.

4. The method of claim 1, further comprising measuring at least one of the following operating parameters of the unequipped vehicle relative to the equipped vehicle:

location;

acceleration;

change in speed;

speed increase;

speed decrease;

directional heading;

or change in directional heading.

5. The method of claim 1, further comprising measuring operating parameters of the unequipped vehicle using at least one of radar and sonar present on the equipped vehicle.

6. The method of claim 1, further comprising measuring operating parameters of the unequipped vehicle using 360°

radar present on the equipped vehicle.

7. The method of claim 1, further comprising measuring operating parameters of the unequipped vehicle using a camera present on the equipped vehicle.

8. The method of claim 1, further comprising transmitting from the equipped vehicle the measured operating parameters of the unequipped vehicle using dedicated short range communications (DSRC).

9. The method of claim 1, further comprising transmitting from the equipped vehicle the measured operating parameters of the unequipped vehicle as a basic safety message (BSM) using dedicated short range communications (DSRC).

10. The method of claim 1, further comprising transmitting from the equipped vehicle a basic safety message including vehicle operating parameters of the equipped vehicle including at least one of the following:

GPS coordinates;

speed;

or acceleration.

11. A method for generating one or more proxy messages including vehicle operating parameters comprising:

receiving at a primary equipped vehicle messages from secondary equipped vehicles, the messages identifying positions of each one of the secondary equipped vehicles;

comparing the positions of the secondary equipped vehicles with positions of unequipped vehicles detected by the primary equipped vehicle for which no messages have been received;

generating at the primary equipped vehicle a proxy message for each one of the unequipped vehicles including operating parameters of the unequipped vehicles; and

transmitting from the primary equipped vehicle to the secondary equipped vehicles the proxy messages generated for each one of the unequipped vehicles to inform the secondary equipped vehicles of the operating parameters of the unequipped vehicles.

12. The method of claim 11, further comprising measuring the operating parameters of each one of the unequipped vehicles relative to the primary equipped vehicle.

13. The method of claim 11, further comprising measuring at least one of the following operating parameters of the unequipped vehicles relative to the equipped vehicle:

location;

acceleration;

change in speed;

speed increase;

speed decrease;

directional heading;

or change in directional heading.

14. The method of claim 11, further comprising measuring operating parameters of the unequipped vehicles using monitoring equipment present on the equipped vehicle including at least one of radar and sonar.

15. The method of claim 11, further comprising receiving at the primary equipped vehicle the messages from the secondary equipped vehicles in the form of basic safety messages (BSMs);

and

transmitting from the primary equipped vehicle to the secondary equipped vehicles the proxy messages in the form of BSMs.

16. The method of claim 15, further comprising transmitting the BSMs using dedicated short range communications (DSRC).

17. A method for generating at least one proxy basic safety message (PBSM) including vehicle operating parameters comprising:

identifying locations of secondary vehicles proximate to a primary vehicle using identification equipment of the primary vehicle;

comparing positions of the secondary vehicles identified by the primary vehicle to vehicle positions set forth in basic safety messages (BSMs) received by the primary vehicle;

designating as secondary equipped vehicles the secondary vehicles identified by the primary vehicle having positions that match the vehicle positions set forth in the BSMs received by the primary vehicle;

designation as secondary unequipped vehicles the secondary vehicles identified by the primary vehicle having positions that do not match the vehicle positions set forth in the BSMs received by the primary vehicle;

generating at the primary vehicle the PBSM for each one of the secondary unequipped vehicles including operating parameters of the unequipped vehicles; and

transmitting from the primary vehicle to the secondary equipped vehicles the PBSMs to inform the secondary equipped vehicles of the operating parameters of the secondary unequipped vehicles.

18. The method of claim 17, further comprising transmitting the BSMs and PBSMs using dedicated short range communications (DSRC).

19. The method of claim 17, further comprising identifying locations of the secondary vehicles proximate to the primary vehicle using at least one of radar and sonar.

20. The method of claim 17, wherein the vehicle operating parameters include at least one of the following:

location;

acceleration;

change in speed;

speed increase;

speed decrease;

directional heading;

or change in directional heading.
