Abstract

Featured is an accurate and inexpensive system to detect and report engine idling in a vehicle including a detection portion and a reporting portion. The detection portion detects or senses the presence of voltage from the vehicle'"'"'s ignition switch and vehicle'"'"'s mechanical vibration from the running engine. The detection portion also can filter out transient vibrations which are not related to engine running. The detection portion forwards signal or information relating to engine running and vehicle movement to a reporting portion of the system. The reporting portion (e.g., a software application being executed on a computer or microprocessor) determines from the forwarded information if the vehicle engine is idling and if there is excessive idling. The fleet operator can define recommended maximum idling parameters to determine such excessive idling. Also featured are apparatuses, devices and methods related thereto.

Claims

1. A system to detect and report engine idling in a vehicle, comprising:

a detection portion that detects two parameters associated with engine running,

wherein one of the parameters being detected is a mechanical characteristic that is present when the engine is running and is not present when the engine is not running; and

a reporting portion that determines from the two detected parameters if the vehicle engine is idling.

2. The system of claim 1, wherein the mechanical characteristic being detected is a mechanical vibration.

3. The system of claim 2, wherein the other characteristic being detected is presence of voltage from the vehicle'"'"'s ignition switch.

4. The system of claim 1, wherein the detection portion is further configured so as to filter out vibrations not related to engine running.

5. The system of claim 1, wherein the system further includes a vehicle movement portion that provides vehicle location information to the reporting portion to determine GPS if the vehicle is moving or not moving.

6. The system of claim 1, wherein the reporting portion includes a computer and a software application program for execution on the computer, wherein the applications program includes instructions and criteria for determining if the vehicle is moving or not moving and if it is determined that the vehicle is not moving to determine if the vehicle'"'"'s engine is idling.

7. The system of claim 6, wherein the software application program for execution on the computer, further includes instructions and criteria for specifying one or maximum idling parameters and for determining if the vehicle'"'"'s engine is idling for more than a predetermined amount of time based on the specified one or more idling parameters.

8. The system of claim 1, wherein the detection portion includes a vibration sensor for sensing vehicle vibration.

9. The system of claim 8, wherein the detection portion further includes timing circuitry that is configured so as determine if the vibrations are continuous for at least a predetermined time.

10. An apparatus for determining if an engine of a vehicle is running;

said apparatus including;

a detector that detects two parameters associated with engine running,

wherein one of the parameters being detected is a mechanical characteristic that is present when the engine is running and is not present when the engine is not running; and

a processor that determines from the two detected parameters if the vehicle engine is idling.

11. The apparatus of claim 10, wherein the mechanical characteristic being detected is a mechanical vibration.

12. The apparatus of claim 11, wherein the other characteristic being detected is presence of voltage from the vehicle'"'"'s ignition switch.

13. The apparatus of claim 10, wherein the detection portion is further configured so as to filter out vibrations not related to engine running.

14. A method for detecting and report engine idling in a vehicle, comprising:

detecting, by a detector, two parameters associated with engine running, wherein one of the parameters being detected is a mechanical characteristic that is present when the engine is running and is not present when the engine is not running; and

determining, by a processor, when the vehicle engine is idling based on the two detected parameters.

15. The apparatus of claim 14, wherein the mechanical characteristic being detected is a mechanical vibration.

16. The method of claim 14, wherein the other characteristic being detected is presence of voltage from the vehicle'"'"'s ignition switch.

17. The method of claim 14, further comprising:

filtering out vibrations not related to engine running.
