Abstract

Systems and methods for operating a vehicle that includes a direct current to alternating current converter is described. In one example, an indication of an air flow restriction of the direct current to alternating current converter is described. The direct current to alternating current converter may supply power to devices that are external to the vehicle.

Claims (27)

1. A method for operating a vehicle that includes a direct current to alternating current converter, comprising:

modeling a temperature of the direct current to alternating current converter via a controller;

measuring the temperature of the direct current to alternating current converter via the controller; and

generating an indication to clear an air flow path to the direct current to alternating current converter in response to the measured temperature being greater than the modeled temperature for greater than a threshold amount of time, wherein the modeled temperature is a function of a position of a window.

2. The method of claim 1 , where the modeled temperature is further a function of one or more of ambient temperature, a seat position, power input to the direct current to alternating current converter, and power output from the direct current to alternating current converter.

3. The method of claim 1 , where the indication is presented via a human to machine interface.

4. The method of claim 1 , where the indication is presented via a personal communications device.

5. A method for operating a vehicle that includes a direct current to alternating current converter, comprising:

modeling a temperature of the direct current to alternating current converter via a controller;

measuring the temperature of the direct current to alternating current converter via the controller; and

generating an indication to clear an air flow path to the direct current to alternating current converter in response to the measured temperature being greater than the modeled temperature for greater than a threshold amount of time, where the modeled temperature is a function of a seat position.

6. The method of claim 5 , where the modeled temperature is further a function of a speed of a fan of the direct current to alternating current converter.

7. The method of claim 5 , where the modeled temperature is further a function of power input to the direct current to alternating current converter.

8. The method of claim 5 , where the modeled temperature is further a function of power output from the direct current to alternating current converter.

9. A method for operating a vehicle that includes a direct current to alternating current converter, comprising:

adjusting a climate control system via a controller in response to a temperature of a direct current to alternating current converter, where adjusting the climate control system includes adjusting a position of a vent control valve.

10. The method of claim 9 , where adjusting the position of the vent control valve increases air flow to floor vents.

11. The method of claim 9 , where adjusting the climate control system includes adjusting a speed of a climate control system fan.

12. The method of claim 9 , further comprising adjusting a speed of a fan of the direct current to alternating current converter.

13. The method of claim 9 , where adjusting the climate control system includes adjusting a speed of a compressor.

14. A system, comprising:

a vehicle including a direct current to alternating current converter and a human/machine interface;

a climate control system; and

a controller including executable instructions stored in non-transitory memory to indicate a temperature of the direct current to alternating current converter is greater than a desired temperature via the human/machine interface, and adjusting the climate control system by adjusting a position of a vent;

where the vent is adjusted in response to the temperature of the direct current to alternating current converter being greater than the desired temperature.

15. The system of claim 14 , where adjusting the climate control system further includes adjusting a speed of a fan.

16. The system of claim 14 , where the human/machine interface is a phone.
