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.
