Abstract

Methods and systems are provided for controlling a temperature of a processor of a controller. In one embodiment, a method includes: identifying a status of at least one task of a plurality of software tasks performed on a first processor to be a hot task based on the software task'"'"'s contribution to a temperature of the first processor; and selectively controlling the temperature of the first processor based on the identified status.

Claims

1. A method for controlling a temperature of a first processor of a vehicle controller having the first processor and a second processor, comprising:

collecting and storing measurement data associated with the temperature of the first processor;

selectively identifying a status of a task of a plurality of software tasks performed on the first processor to be one of a hot task and a cold task based on the software task'"'"'s contribution to the temperature of the first processor, wherein the selectively identifying is based on processing the measurement data with a temperature predictor model; and

selectively controlling the temperature of the first processor based on the identified status.

3. The method of claim 1, wherein the identifying the status of the task to be a cool task is further based on an ability of the task to bring down the temperature of the first processor.

4. The method of claim 1, wherein the selectively controlling comprises migrating the hot task identified as a hot task from the first processor to the second processor.

5. The method of claim 4, wherein the selectively controlling further comprises generating controls signals to control a cooling device.

7. The method of claim 1, further comprising determining a temperature of the second processor of the vehicle controller and wherein the selectively controlling the temperature of the first processor is based on the temperature of the second processor.

8. The method of claim 1, wherein the selectively controlling the temperature of the first processor comprises terminating a software module associated with the at least one hot task identified as a hot task.

9. The method of claim 8, further comprising generating a warning signal that includes a notification of an unavailability of a feature associated with the software module.

10. The method of claim 1, wherein the identifying the status of the task to be a hot task is based on the software task'"'"'s contribution to a temperature of memory associated with the first processor.

11. A system for controlling a temperature of a first processor of a vehicle controller having the first processor and a second processor, comprising:

a non-transitory computer readable medium comprising;

a first module that collects measurement data associated with the temperature of the first processor;

a second module that selectively identifies a status of a task of a plurality of software tasks performed on the first processor to be one of a hot task and a cool task based on the software task'"'"'s contribution to the temperature of the first processor, wherein the second module selectively identifies based on processing the measurement data with a temperature predictor model; and

a third module that selectively controls the temperature of the first processor based on the identified status.

14. The system of claim 11, wherein the third module selectively controls by migrating the at least one hot task identified as a hot task from the first processor to the second processor.

15. The system of claim 14, wherein third module selectively controls by generating controls signals to control a cooling device.

17. The system of claim 11, further comprising a fourth module that determines a temperature of the second processor and wherein the third module selectively controls the temperature of the first processor based on the temperature of the second processor.

18. The system of claim 11, wherein the third module selectively controls the temperature of the first processor by terminating a software module associated with the task identified as a hot task.

19. The system of claim 18, wherein the third module generates a warning signal that includes a notification of an unavailability of a feature associated with the software module.

20. The system of claim 11, wherein the second module identifies the status of the task to be a hot task further based on the software task'"'"'s contribution to a temperature of memory associated with the first processor.

12. (canceled)

13. The system of claim 12, wherein the second module identifies the status of the task to be a cool task further based on an ability of the task to bring down the temperature of the first processor.
