A service unit for providing a convenience service to a cab of a tractor trailer includes a supply panel which is operable to attach to a cab of a tractor trailer. The supply panel provides conditioned air to the cab. A vibration detection unit is configured to interact with the supply panel and detect an idling engine by detecting a vibration with a vibration detector, transmitting the vibration as vibration signals to a controller, performing a signal analysis on the vibration signals to identify an engine idle signature, and storing a duration of the engine idle signature.

1. A service unit for providing a convenience service to a cab of a tractor trailer, comprising: a supply panel operable to selectively attach to a cab of a tractor trailer, said supply panel providing conditioned air to said cab; anda controller in electrical communication with a vibration detector and the supply panel, the controller configured to receive vibration signals relating to the tractor trailer from the vibration detector and identify an idling engine of the tractor trailer based on the received vibration signals, wherein the controller causes the supply panel to take an action based on the identification of the idling engine; wherein the vibration detector is incorporated into the service unit. 2. The service unit of claim 1 wherein the supply panel is further operable to provide at least one convenience service selected from the group consisting of radio signals, electrical power, telephone, computer network, and video. 3. The service unit of claim 1 wherein the controller is further operable to activate said service unit. 4. The service unit of claim 1 wherein the supply panel comprises a display and wherein the controller is operable to send a message to the display. 5. The service unit of claim 1 wherein the vibration detector and the controller communicate using an RS232 protocol. 6. The service unit of claim 1 wherein the service unit is operable to: transmit the vibration signals from the vibration detector to the controller;perform a signal analysis by the controller on the vibration signals to identify an engine idle signature; andin response to identifying an engine idle signature, store a duration of the engine idle signature. 7. The service unit of claim 1, further comprising: a service module that houses the supply panel and is operable to fit into a window opening of the tractor trailer, wherein at least one of the vibration detector or controller is incorporated into the service module. 8. The service unit of claim 1, wherein the controller is operable to discontinue services provided by the supply panel in response to detecting a period of continued engine idling. 9. The service unit of claim 1, wherein the controller is operable to determine if the supply panel is coupled to the tractor trailer. 10. The service unit of claim 9, wherein the controller is operable to determine if the supply panel is coupled to the tractor trailer based on angle data filtered from the vibration signals received from the vibration detector. 11. The service unit of claim 1, wherein the controller is further operable to differentiate between vibration signals relating to an idling engine of the tractor trailer and vibration signals relating to other sources. 12. The service unit of claim 11, wherein the other sources comprise at least one of a transport refrigeration unit, an auxiliary power unit, movement within the tractor trailer, or a neighboring vehicle. 13. The service unit of claim 1, wherein the action taken by the supply panel that is caused by the controller comprises that the supply panel: display a notice on a display of the supply panel; andif the identification of the idling engine continues after the notice is displayed, shut down service from the supply panel.
