Abstract

An engine coolant temperature at an expected time of activation of a vehicle is predicted. Upon determining that the predicted engine coolant temperature is greater than an ambient air temperature by a temperature threshold, a vehicle component is actuated at a time determined based on the expected time of activation.

Claims

1. A system, comprising a computer programmed to:

predict an engine coolant temperature at an expected time of activation of a vehicle; and

upon determining that the predicted engine coolant temperature is greater than an ambient air temperature by a temperature threshold, actuate a vehicle component at a time determined based on the expected time of activation.

2. The system of claim 1, wherein the computer is further programmed to perform a fuel line leak diagnostic upon activation of the vehicle when the predicted engine coolant temperature is within the temperature threshold of the ambient air temperature.

3. The system of claim 1, wherein the vehicle component is a suspension and the computer is further programmed to actuate the suspension to raise a front end of the vehicle.

4. The system of claim 1, wherein the vehicle component is a front hood of the vehicle and the computer is further programmed to open the front hood.

5. The system of claim 1, wherein the vehicle component is a propulsion and the computer is further programmed to identify a roadway having a road grade greater than a road grade threshold and to actuate the propulsion to move the vehicle to the identified roadway.

6. The system of claim 1, wherein the vehicle component is a propulsion and the computer is further programmed to determine a wind direction and to actuate the propulsion to align the vehicle along the wind direction.

7. The system of claim 1, wherein the computer is further programmed to collect a plurality of measurements of the engine coolant temperature and to predict the engine coolant temperature at the expected time of activation of the vehicle based on the measurements.

8. The system of claim 7, wherein each of the plurality of measurements is collected at a predetermined period of time that is measured from one of:

a previous measurement and a time of deactivation of the vehicle.

9. The system of claim 1, wherein the computer is further programmed to detect an insolation on the vehicle and to actuate a propulsion to move the vehicle when the insolation is above an insolation threshold.

10. The system of claim 9, wherein the computer is further programmed to identify a location having an insolation below the insolation threshold and to actuate the propulsion to move the vehicle to the location.

11. A method, comprising:

predicting an engine coolant temperature at an expected time of activation of a vehicle; and

upon determining that the predicted engine coolant temperature is greater than an ambient air temperature by a temperature threshold, actuating a vehicle component at a time based on the expected time of activation.

12. The method of claim 11, further comprising performing a fuel line leak diagnostic upon activation of the vehicle when the predicted engine coolant temperature is within the temperature threshold of the ambient air temperature.

13. The method of claim 11, wherein the vehicle component is a suspension, and the method further comprises actuating the suspension to raise a front end of the vehicle.

14. The method of claim 11, wherein the vehicle component is a front hood of the vehicle, and the method further comprises opening the front hood.

15. The method of claim 11, wherein the vehicle component is a propulsion, and the method further comprises identifying a roadway having a road grade greater than a road grade threshold and actuating the propulsion to move the vehicle to the identified roadway.

16. The method of claim 11, wherein the vehicle component is a propulsion, and the method further comprises determining a wind direction and to actuate the propulsion to align the vehicle along the wind direction.

17. The method of claim 11, further comprising collecting a plurality of measurements of the engine coolant temperature and predicting the engine coolant temperature at the expected time of activation of the vehicle based on the measurements.

18. The method of claim 17, wherein each of the plurality of measurements is collected at a predetermined period of time that is measured from one of:

a previous measurement and a time of deactivation of the vehicle.

19. The method of claim 11, further comprising detecting an insolation on the vehicle and to actuate a propulsion to move the vehicle when the insolation is above an insolation threshold.

20. The method of claim 19, further comprising identifying a location having an insolation below the insolation threshold and to actuate the propulsion to move the vehicle to the location.
