Absolute acceleration sensor for use within moving vehicles

A system for shutting down an engine of a vehicle comprising:

• a. a first sensor for detecting that the vehicle has stopped based on a speed of the vehicle and acceleration of the vehicle;
• b. a second sensor for detecting a non-drive status of the vehicle;
• and
• c. a control device coupled to the first sensor and the second sensor, wherein the control device receives a signal from the first sensor that the vehicle has stopped and receives a signal from the second sensor based on the non-drive status of the vehicle, wherein based on the stopping of the vehicle and the non-drive transmission status of the vehicle, the control device is configured to shut down the engine after a specified amount of time.

A system for a vehicle comprising:

• a. a first sensor for detecting that the vehicle has stopped based on a speed of the vehicle and acceleration of the vehicle;
• b. a second sensor for detecting a non-drive status of the vehicle;
• c. an alerting device that is activated based on a stopping of the vehicle and the non-drive status of the vehicle, wherein based on the stopping of the vehicle and the non-drive transmission status of the vehicle, shutting down an engine of the vehicle after a specified amount of time;
• and
• d. a temperature sensor for detecting a temperature outside of the vehicle, wherein the engine is not shutdown unless the temperature is above a programmed value.
