Abstract

The present invention provides methods, apparatus, and systems for improving the fuel economy of an automobile. An automobile may be configured to receive data relating to a path traversed by the automobile from a server or from other automobiles traveling the path. The path data may indicate one or more road conditions such as traffic patterns, slopes, and the like. In response to receiving the path data, the automobile may automatically adjust the contribution of one or more components of the automobile configured to set the automobile in motion, to conserve fuel or otherwise improve some other performance characteristic of the automobile. For example, the number of cylinders used to operate the vehicle and the electric motor assistance ratios may be adjusted.

Claims

1. A method for improving fuel economy of a vehicle, comprising:

sending a request for data related to the condition of a path traveled by the vehicle by a first computer on-board the vehicle to a second computer;

receiving, by the first computer, the requested data related to the condition of the path sent by the second computer; and

in response to receiving the data, adjusting the contribution of one or more components of the vehicle configured to set the vehicle in motion based on the received data.

2. The method of claim 1, wherein the two or more components comprise two or more cylinders of the vehicle and the adjusting comprises selecting the number of cylinders used to operate the vehicle.

3. The method of claim 2, wherein fewer cylinders are used to operate the vehicle if the vehicle is expected to travel at a relatively steady speed.

4. The method of claim 1, wherein the vehicle is a hybrid vehicle, wherein the two or more components comprise:

an internal combustion engine; and

an electric motor.

5. The method of claim 4, wherein the adjusting comprises any combination of:

adjusting the amount of assistance provided by the electric motor to operate the vehicle; and

starting or stopping the use of the internal combustion engine based on forecasted usage.

6. The method of claim 4, further comprising:

identifying path conditions that offer opportunities to charge batteries powering the electric motor based on the data related to the condition of the path and adjusting the contribution of the electric motor based on the identified opportunities; and

selecting an alternative path to elongate the distance that can be traveled by the vehicle based on available fuel for the internal combustion engine, power available to the electric motor, and the data related to the condition of the path.

7. The method of claim 1, further comprising:

receiving, by a server, the requests from the vehicle, wherein the server is the second computer; and

in response to receiving the request, providing, by the server to the vehicle, the data related to the condition of the path, wherein the data is the average of data received from one or more other vehicles traveling on the path.

8. The method of claim 1, further comprising receiving the requests from the vehicle by one or more other vehicles traveling the path and providing, by a computer associated with each of the one or more other vehicles to the vehicle, the data related the condition of the path, wherein

each of the computers associated with the one or more other vehicles is the second computer;

and

the first computer is configured to compute an average for data received from the one or more other vehicles.

9. The method of claim 8, wherein the one or more other vehicles are of the same type as the vehicle.

10. The method of claim 1, further comprising, if the requested data is not received by the first computer, adjusting the contribution of the one or more components of the vehicle configured to set the vehicle in motion based on historic data related to the path stored in the first computer.

11. The method of claim 1, wherein the data related to the condition of the path comprises one or more of:

braking and acceleration metrics for vehicles traveling on the path;

gradients and slopes along the path;

traffic patterns along the path;

driving speeds along the path; and

speed limits along the path.

12. The method of claim 1, further comprising storing in the first computer the data related to the condition of the path each time the path is traveled and adjusting the contribution of the two or more components of the vehicle configured to set the vehicle in motion based on the stored data.

13. A method for improving fuel economy of a hybrid vehicle comprising an internal combustion engine and an electric motor, comprising:

sending a request for data related to the condition of a path traveled by the hybrid vehicle by a first computer on-board the vehicle to a second computer;

receiving, by the first computer, the requested data related to the condition of the path sent by the second computer; and

in response to receiving the data, adjusting the contribution of the internal combustion engine and the electric motor to the motion of the hybrid vehicle based on the received data.

14. The method of claim 13, further comprising, adjusting the contribution of two or more cylinders of the hybrid vehicle to the motion of the hybrid vehicle, wherein the adjusting comprises selecting the number of cylinders used to operate the automobile.

15. The method of claim 13, wherein the adjusting comprises any combination of:
