Abstract

A method, system, and apparatus to detect when one or more moving vehicles are close to a first vehicle, and to take necessary actions to maintain a minimum distance between vehicles in a dynamic environment by automatic navigation. A computer method and apparatus for automobile accident reduction by maintaining a minimum distance with respect to all nearby vehicles on the road. In addition, methods to synchronously move a group of vehicles on a highway through a swarming action where each vehicle keeps a region immediately around it free of other vehicles while maintaining the speed of the vehicle immediately in front or nearby is also disclosed.

Claims

1. A method comprising

wherein the first communication signal provides a first instruction to the second vehicle to move in a first manner; and

further comprising using the second computer processor on the second vehicle to cause the second vehicle to move in the first manner in response to the first instruction.

3. The method of claim 1 wherein

the first instruction to the second vehicle to move in the first manner instructs the second vehicle to slow down.

4. The method of claim 1 wherein

the transmitting of the first communication signal from the first vehicle to the second computer processor on the second vehicle is done after and only if the first computer processor determines that the first vehicle is not allowed to move in a second manner.

9. The method of claim 1 wherein

the first instruction to the second vehicle to move in the first manner instructs the second vehicle to accelerate.

10. The method of claim 1 wherein

the first instruction to the second vehicle to move in the first manner instructs the second vehicle to change direction of movement of the second vehicle.

23. The method of claim 1 wherein

the first instruction to the second vehicle to move in the first manner instructs the second vehicle to steer the second vehicle in a particular direction.

2. A method comprising

using a first computer processor on a first vehicle to communicate with a second computer processor on a second vehicle;

and

using a common pre-determined protocol as programmed by computer software to decide a combined movement of the first vehicle and the second vehicle based on the communication of the first computer processor on the first vehicle with the second computer processor on the second vehicle.

5. The method of claim 2 wherein

the combined movement of the first vehicle and the second vehicle is determined so as to maintain an inner region for each of the first vehicle and the second vehicle free from the other vehicle of the first and the second vehicle and free from any other vehicle.

6. The method of claim 5 wherein

the inner region of the first vehicle is an elliptical area having its center as the center of the first vehicle;

and wherein the inner region of the second vehicle is an elliptical area having its center as the center of the second vehicle.

7. A method comprising

using communications between a first computer processor on a first vehicle and a second computer processor on a second vehicle to synchronize a speed of the first vehicle to be about equal to a speed of the second vehicle subject to a minimum distance requirement between the first vehicle and the second vehicle.

8. The method of claim 7 further comprising

using communications between a third computer processor on a third vehicle and the second computer processor on the second vehicle to synchronize a speed of the third vehicle to be about equal to a speed of the second vehicle subject to a minimum distance requirement between the third vehicle and the second vehicle;

wherein communications, if any, between the first computer processor and the third computer processor are not used to synchronize the speed of the third vehicle to be about equal the speed of the second vehicle subject to the minimum distance requirement between the third vehicle and the second vehicle.

11. The method of claim 7 wherein

the second vehicle and the first vehicle are travelling on the same road, and in substantially the same direction;

and the second vehicle is ahead of the first vehicle on the road.

12. An apparatus comprising
