Abstract

A method for preconditioning various subsystems of an electrified vehicle according to an exemplary aspect of the present disclosure includes, among other things, scheduling preconditioning of a battery pack, an interior cabin, a transmission and an engine of the electrified vehicle prior to a next expected usage time based at least on a weather forecast.

First claim

What is claimed is:

1. A method for preconditioning various subsystems of an electrified vehicle, comprising:
automatically preconditioning a battery pack, an interior cabin, a transmission, and an engine of the electrified vehicle prior to a next expected usage time based at least on a weather forecast, wherein the preconditioning is controlled by a vehicle control system and includes preconditioning the battery pack first, then preconditioning the interior cabin, then preconditioning the engine, and then preconditioning the transmission.

2. The method as recited in claim 1 , wherein the preconditioning includes determining the next expected usage time associated with the electrified vehicle.

3. The method as recited in claim 2 , wherein determining the next expected usage time includes inferring the next expected usage time based on historical usage information associated with the electrified vehicle.

4. The method as recited in claim 3 , wherein the historical usage information is updated each time the engine is started or a plug is removed from a charging outlet of the electrified vehicle.

5. The method as recited in claim 2 , wherein determining the next expected usage time includes receiving instructions from a user about a planned usage of the electrified vehicle.

6. The method as recited in claim 1 , comprising determining whether the electrified vehicle is on plug prior to the preconditioning.

7. The method as recited in claim 1 , comprising gathering temperature information from the various subsystems prior to the preconditioning.

8. The method as recited in claim 1 , comprising obtaining the weather forecast from a web-based server.

9. The method as recited in claim 8 , comprising communicating with the web-based server over a cloud to obtain the weather forecast.

10. The method as recited in claim 1 , comprising actuating at least one touch point of the electrified vehicle based at least on the next expected usage time and the weather forecast.

11. The method as recited in claim 10 , wherein the at least one touch point includes a steering wheel, a vehicle seat, a window, a side mirror, or a gear shifter.

12. The method as recited in claim 1 , comprising actuating a conditioning device of each of the battery pack, the engine, the transmission, and the interior cabin at a scheduled time to execute the preconditioning.

13. The method as recited in claim 1 , comprising prioritizing preconditioning of one of the engine, the battery pack, the interior cabin, and the transmission over the other of the engine, the battery pack, the interior cabin, and the transmission.

14. The method as recited in claim 1 , comprising adjusting a temperature of an engine coolant such that the temperature is within a desired operating range at a scheduled time to execute the preconditioning.

15. The method as recited in claim 1 , comprising adjusting a temperature of a transmission fluid such that the temperature is within a desired operating range at a scheduled time to execute the preconditioning.

16. The method as recited in claim 1 , comprising adjusting a temperature of the battery pack such that the temperature is within a desired operating range at a scheduled time to execute the preconditioning.

17. The method as recited in claim 1 , comprising actuating at least one touch point of the electrified vehicle after preconditioning each of the battery pack, the interior cabin, the engine, and the transmission.

18. The method as recited in claim 1 , wherein the weather forecast includes a prediction of a state of ambient surroundings at a location of the electrified vehicle and at an estimated date and time that is consistent with the next expected usage time.

19. An electrified vehicle, comprising:
a plurality of vehicle subsystems including an engine, a battery pack, a transmission, and an interior cabin;
a plurality of touch points; and
a control system configured with instructions for preconditioning said battery pack first, then preconditioning said interior cabin, then preconditioning said engine, then preconditioning said transmission, and then actuating said plurality of touch points prior to a next expected usage time based at least on a weather forecast.

20. The electrified vehicle as recited in claim 19 , wherein said plurality of touch points include at least a steering wheel, a vehicle seat, a gear shifter, and a side mirror.

21. The electrified vehicle as recited in claim 19 , wherein each of said plurality of vehicle subsystems includes a sensor configured to monitor temperatures, said control system configured to monitor said temperatures for scheduling said preconditioning.

22. The electrified vehicle as recited in claim 19 , wherein said control system includes a transceiver configured to communicate with a server over a cloud to obtain said weather forecast.

23. The electrified vehicle as recited in claim 19 , wherein said plurality of touch points include an arm rest or a floor mat.
