Engine running notice and automatic shut-off

1. A vehicle comprising:

an engine;

a plurality of sensors;

an engine kill device coupled to the engine, wherein the engine kill device is configured to stop the engine;

a notice device;

a response link; and

a controller coupled to the engine kill device, the plurality of sensors, the notice device, and the response link, wherein the controller is configured to evaluate signals from the plurality of sensors and issue a notice when the signals from the plurality of sensors meet predetermined criteria, and wherein the controller is further configured to activate the engine kill device if the response link is not activated after the notice is issued, and wherein the controller is configured to terminate monitoring to determine if the engine has been errantly left running upon activation of the response link indicating the engine should remain running.

2. The vehicle of claim 1 further comprising a timer coupled to the controller, wherein the controller is further configured to activate the engine kill switch if the response link is not activated within a set response time after the notice is issued.

3. The vehicle of claim 1 wherein the notice device further comprises a local notice device and a transmitter, and wherein the controller is configured to evaluate the signals received from the plurality of sensors to select the notice device used for issuing the notice.

4. The vehicle of claim 1 wherein the response link further comprises a local acknowledgement directly coupled to the vehicle, and a receiver configured to receive a signal from a remote user.

5. The vehicle of claim 1 wherein the plurality of sensors comprises:

an engine running sensor that detects when the engine is running; and

a speed sensor that detects the speed of the vehicle;

wherein the controller is configured to require a positive signal from the engine running sensor and a speed sensor reading of less than a lower limit to issue the notice.

6. The vehicle of claim 5 wherein the plurality of sensors further comprise:

a key fob sensor that detects a key fob, wherein the key fob sensor detects if the key fob is within the vehicle, outside of the vehicle but within a preset range of the vehicle, or outside of the preset range of the vehicle; and

an occupant sensor that detects if a seat in the vehicle is occupied.

7. The vehicle of claim 2 wherein the controller is further configured to require the signals from the plurality of sensors remain constant for a set notification time prior to issuing the notice.

8. The vehicle of claim 3 wherein the local notice device comprises at least one of a horn, a light, and a speaker.

9. The vehicle of claim 3 wherein the transmitter is configured to transmit the notice using at least one of a text message, a phone call, a page, or an e-mail.

10. A vehicle comprising:

an engine;

an engine kill device capable of turning the engine off, wherein the kill device is coupled to the engine;

means for determining if the engine has been errantly left running;

means for issuing a notice that the engine has been left running;

means for receiving a response from a user; and

a controller coupled to the engine kill device, wherein the controller is configured to activate the engine kill device if no response is received from the user within a set response time after the notice was issued, and wherein the controller is configured to terminate monitoring to determine if the engine has been errantly left running upon receipt of the response indicating the engine should remain running.

11. The vehicle of claim 10 wherein the means for determining if the engine has been errantly left running comprises a plurality of sensors coupled to the controller, wherein the plurality of sensors comprises at least an engine running sensor and a speed sensor, and wherein a positive signal from the engine running sensor and a reading of less than a lower limit from the speed sensor is required to determine the engine may have been errantly left running.

12. The vehicle of claim 10 wherein the means for receiving a response from the user comprises a response link, and wherein the response link comprises a local acknowledgement and a receiver.

13. The vehicle of claim 10 wherein the means for issuing a notice to the user comprises at least one of a horn, a light, a radio, or a transmitter.

14. A method of automatically turning a vehicle engine off, the method comprising:

receiving signals from a plurality of sensors at a controller, and wherein the controller evaluates the signals to determine if the engine may have been errantly left running;

sending a notice indicating the engine may have been errantly left running;

turning the engine off if no response is received within a set response time after the notice was sent; and

providing a response link configured for a human to indicate the engine should remain running, wherein activation of the response link to indicate the engine should remain running advances the controller to a stop action that terminates monitoring to determine if the engine may have been errantly left running.

15. The method of claim 14 wherein turning the engine off further comprises turning the engine off if a user provides instructions to turn the engine off within the set response time.

16. The method of claim 14 wherein determining the engine may have been errantly left running further comprises determining that the engine is running, and determining that a vehicle speed is less than a lower limit.

17. The method of claim 14 wherein determining the engine may have been errantly left running further comprises receiving, at the controller, signals from a plurality of sensors, and wherein the controller evaluates the signals to determine if the engine may have been errantly left running.

18. The method of claim 14 wherein sending the notice further comprises transmitting at least one of a short message service (SMS) or a push notification.

19. The method of claim 14 wherein sending the notice further comprises at least one of honking a horn, flashing a light, or activating a speaker.

20. The method of claim 14 wherein providing the response link comprises providing the response link comprising a local acknowledgement and a receiver.
