Abstract

Method and apparatus are disclosed for secure idle for a vehicle generator. An example vehicle includes an outlet external to the vehicle, a power inverter dedicated to supplying AC power to the outlet, and a powertrain control module. The powertrain control module controls the power inverter to supply first power level when a switch is in a first position and a second power level when the switch is in a second position. Additionally, the powertrain control module, after entering a secure mode, controls an engine to remain idling when an ignition switch is off.

First claim

What is claimed is:

1. A vehicle comprising:
an outlet external to the vehicle;
a power inverter dedicated to supplying AC power to the outlet; and
a powertrain control module to:
control the power inverter to supply a first power level when a switch is in a first position and a second power level when the switch is in a second position;
after entering a secure mode, control an engine to remain idling when an ignition switch is off; and
provide, via an instrument panel cluster, a warning when a plug-in detector detects a plug in the outlet and a gear selector is shifted out of park.

2. The vehicle of claim 1 , including a second switch.

3. The vehicle of claim 1 , wherein when in the secure mode, the powertrain control module is to terminate the engine in response to detecting the gear selector being shifted from park.

4. The vehicle of claim 1 , wherein the outlet is a first outlet, and including a second outlet internal to the vehicle, the power inverter dedicated to supplying the AC power to the first and second outlets.

5. The vehicle of claim 1 , wherein the outlet includes the plug-in detector.

6. The vehicle of claim 2 , including a body control module, and wherein to enter the secure mode, the body control module is to detect the ignition switch is off, a key is removed from the ignition switch, and a position of the second switch is indicative of the secure mode.

7. The vehicle of claim 6 , wherein, when in the secure mode, the powertrain control module is to control the power inverter to supply the second power level.

8. The vehicle of claim 2 , wherein the powertrain control module is to control the power inverter to supply the first power level when the second switch is in a first position and the second power level when the second switch is in a second position.

9. The vehicle of claim 2 , wherein the switch is external to the vehicle and the second switch is internal to the vehicle.

10. A vehicle comprising:
an outlet external to the vehicle;
a power inverter dedicated to supplying AC power to the outlet; and
a powertrain control module to:
control the power inverter to supply a first power level when a switch is in a first position and a second power level when the switch is in a second position;
after entering a secure mode, control an engine to remain idling when an ignition switch is off;
maintain an idle timer when the power inverter is supplying the second power level; and
when the idle timer expires, control the power inverter to supply the first power level.

11. The vehicle of claim 10 , wherein the powertrain control module is to provide, via an instrument panel cluster, a warning when a plug-in detector detects a plug in the outlet and a gear selector is shifted out of park.

12. The vehicle of claim 10 , wherein the idle timer is set for at least thirty minutes.

13. A vehicle comprising:
an outlet external to the vehicle;
a power inverter dedicated to supplying AC power to the outlet; and
a powertrain control module to:
control the power inverter to supply a first power level when a switch is in a first position and a second power level when the switch is in a second position, wherein the first power level is between 100 Watts and 400 Watts; and
after entering a secure mode, control an engine to remain idling when an ignition switch is off.

14. A vehicle comprising:
an external outlet;
a power inverter dedicated to supplying AC power to the external outlet; and
a powertrain control module to:
control the power inverter to supply a first power level when a switch is in a first position and a second power level of at least 2000 Watts when the switch is in a second position; and
after entering a secure mode, idle an engine when an ignition switch is off.

15. A vehicle comprising:
an outlet external to the vehicle;
a power inverter dedicated to supplying AC power to the outlet; and
a powertrain control module to:
control the power inverter to supply a first power level when a switch is in a first position and a second power level when the switch is in a second position; and
after entering a secure mode, control an engine to remain idling when an ignition switch is off;

a second switch;
a body control module, wherein, to enter the secure mode, the body control module is to detect the ignition switch is off, a key is removed from the ignition switch, and a position of the second switch is indicative of the secure mode; and
an instrument panel cluster to prompt a user to remove the key from the ignition switch when the second switch is toggled to the secure position.

16. The vehicle of claim 15 , wherein the second switch is a physical switch.

17. The vehicle of claim 15 , wherein the second switch is a soft switch provided by an interactive center console display in the vehicle.

18. A vehicle comprising:
an outlet external to the vehicle;
a power inverter dedicated to supplying AC power to the outlet; and
a powertrain control module to:
control the power inverter to supply a first power level when a switch is in a first position and a second power level when the switch is in a second position; and
after entering a secure mode, control an engine to remain idling when an ignition switch is off

a second switch;
a body control module, and wherein to enter the secure mode, the body control module is to detect the ignition switch is off, a key is removed from the ignition switch, and a position of the second switch is indicative of the secure mode; and
an instrument panel cluster to prompt a user to insert the key into the ignition switch when the second switch is toggled to an unsecure position.

19. The vehicle of claim 18 , wherein the second switch is a physical switch.

20. The vehicle of claim 18 , wherein the second switch is a soft switch provided by an interactive center console display in the vehicle.
