Abstract

A computer includes a communication unit for obtaining usage data and/or run-time data associated with the computer, at least one component communicatively coupled to the computer, and/or a vehicle on which the computer is mounted and from which the computer is configured to receive power. The computer further includes a processor configured to: extrapolate out of the usage data and run-time data patterns associated with activities implemented by the computer and/or the at least one component and power states of the vehicle and create and store a profile of patterns; receive an indication that the vehicle has been toggled to one of an ON power state and an OFF power state; identify a pattern associated with the power state of the vehicle; and adapt a power state of the computer and/or the at least one component responsive to the indication and the pattern.

Claims

1. A computer comprising:

a communication unit configured to obtain at least one of usage data and run-time data associated with at least one of the computer, at least one component communicatively coupled to the computer, and a vehicle on which the computer is mounted;

a memory configured to store the usage data and run-time data;

a processor configured to;

extrapolate, out of the usage data and run-time data, patterns associated with activities implemented by at least one of the computer and the at least one component and power states of the vehicle and create and store, on the memory, a profile of patterns;

receive an indication that the vehicle has been toggled to one of an ON power state and an OFF power state, wherein the computer is configured to receive power from the vehicle;

identify a pattern associated with the power state of the vehicle; and

adapt a power state of at least one of the computer and the at least one component, responsive to the indication and the pattern, by predicting when an upcoming ignition detect toggle event will occur by applying one or more mathematical models to collected data and selecting results from a mathematical model determined to have a higher degree of accuracy, the one or more mathematical models including one or more of;

a weighted moving average model, a mathematical model configured to be applied for a predefined period, and a mathematical model that assigns different weights to different positions in a sample window.

2. The computer of claim 1, wherein the usage data includes at least one of activities, processes and components being executed on the computer at least one of before, during, and after receipt of the indication, a date stamp associated with the indication, and a length of time the vehicle is in a power state.

3. The computer of claim 1, wherein the run-time data includes at least one of data obtained from one or more sensors and operation conditions of at least one of the vehicle, the computer, and the at least one component.

4. The computer of claim 1, wherein, based on the pattern, the processor is configured to anticipate future usage and responsively adapt the power state of at least one of the computer and the at least one component based on an anticipated future usage.

5. The computer of claim 1, wherein in adapting the power state of at least one of the computer and the at least one component, the processor is configured to determine a length of time the vehicle will remain in the OFF power state and maintain at least one of the computer and the at least one component in an ON state based on the determined length of time.

6. The computer of claim 1, wherein in adapting the power state of at least one of the computer and the at least one component, the processor is configured to determine a length of time the vehicle will remain in the OFF power state and switch at least one of the computer and the at least one component to an OFF state based on the determined length of time.

7. The computer of claim 1, wherein in adapting the power state at least one of the computer and the at least one component, the processor is configured to determine an operating condition of the vehicle and adapt the power state of at least one of the computer and the at least one component responsive to the operating condition.

8. The computer of claim 1, wherein in adapting the power state of at least one of the computer and the at least one component, the processor is configured to determine a user role and adapt the power state of at least one of the computer and the at least one component responsive to the user role.

9. The computer of claim 1, wherein in adapting the power state of at least one of the computer and the at least one component, the processor is configured to use preset user priority preferences provided by a user in creating a power profile, wherein the processor is configured to assign a priority to the preset user priority preferences.

10. A method comprising:

obtaining, by a computer, at least one of usage data and run-time data associated with at least one of the computer, at least one component communicatively coupled to the computer, and a vehicle on which the computer is mounted, wherein the computer is configured to receive power from the vehicle;

extrapolating, out of the usage data and run-time data, patterns associated with activities implemented by at least one of the computer and the at least one component and power states of the vehicle;

creating, by the computer, a profile of patterns;

receiving, by the computer, an indication that the vehicle has been toggled to one of an ON power state and an OFF power state;

identifying, by the computer, a pattern associated with the power state of the vehicle; and

adapting, by the computer, a power state of at least one of the computer and the at least one component, responsive to the indication and the pattern, by predicting, by the computer, when an upcoming ignition detect toggle event will occur by applying one or more mathematical models to collected data and selecting results from a mathematical model determined to have a higher degree of accuracy, the one or more mathematical models including one or more of;

a weighted moving average model, a mathematical model configured to be applied for a predefined period, and a mathematical model that assigns different weights to different positions in a sample window.

11. The method of claim 10, wherein the usage data includes at least one of activities, processes and components being executed on at least one of the computer and the at least one component at least one of before, during, and after receipt of the indication, a date stamp associated with the indication, and a length of time the vehicle is in a power state.

12. The method of claim 10, wherein the run-time data includes at least one of data obtained from one or more sensors and operation conditions of at least one of the computer and the at least one component.

13. The method of claim 10, anticipating, by the computer, future usage and responsively adapting the power state of at least one of the computer and the at least one component based on an anticipated future usage.

14. The method of claim 10, wherein the adapting the power state comprises determining, by the computer, a length of time the vehicle will remain in the OFF power state and maintaining at least one of the computer and the at least one component in an ON state based on the determined length of time.

15. The method of claim 10, wherein the adapting the power state comprises determining, by the computer, a length of time the vehicle will remain in the OFF power state and switching at least one of the computer and the at least one component to an OFF state based on the determined length of time.

16. The method of claim 10, wherein the adapting the power state comprises determining, by the computer, an operating condition of the vehicle and adapting the power state of at least one of the computer and the at least one component responsive to the operating condition.

17. The method of claim 10, wherein the adapting the power state comprises determining, by the computer, a user role and adapting the power state of at least one of the computer and the at least one component responsive to the user role.

18. The method of claim 10, wherein the adapting the power state comprises using, by the computer, preset user priority preferences provided by a user in creating a power profile, wherein the preset user priority preferences assigns a priority to the information received.
