An apparatus and methods are provided for controlling power to interior functions of a trailer of a heavy duty vehicle. The apparatus preferably includes a vehicle trailer adapted to be connected to a heavy duty vehicle and having an interior cargo storage chamber and at least one door for providing access to the interior cargo storage chamber, a power supply connected to the trailer, at least one light source connected to the power supply and mounted within the interior cargo storage chamber of the trailer, and a light controller mounted to the trailer, connected to the power supply and the light source, and responsive to open and closed positions of the at least one door for controlling the power to the at least one light during predetermined periods of time when the at least one door of the trailer is in an open position and a closed position so that when the at least one door is in the open position the at least one light is in an on position having power supplied thereto and when the door is in a closed position the power is prevented from being supplied to the at least one light and thereby cause the at least one light to be in an off position.

Apparatus and method for controlling power to interior trailer functions

An apparatus and methods are provided for data communications associated with a heavy duty vehicle. The apparatus preferably includes at least one electronic subsystem associated with the heavy duty vehicle and a plurality of electrical conductors connected to the at least one electronic subsystem and associated with the heavy duty vehicle. A vehicle data communications protocol converter is preferably connected to the plurality of electrical conductors for converting a first data communications protocol associated with data communications along the plurality of electrical conductors to a second data communications protocol such as an infrared or an RF data communications protocol. The apparatus also preferably includes a transceiver connected to the data communications protocol converter for transmitting the second data communications protocol from the heavy duty vehicle and receiving the data communications protocol from a remote data communications terminal.

Apparatus and method for data communication between heavy duty vehicle

An apparatus and methods are provided for for indicating load weight of a vehicle. The apparatus preferably includes a fluid pressure sensor, such as a transducer, associated with a fluid pressure line of a vehicle for producing a plurality of fluid pressure signals representative of a corresponding plurality of load weights and a load weight indicating device responsive to the sensor for indicating a plurality of load weight levels. The load weight indicating device includes a memory for storing a calibration signal representative of a predetermined load weight limit level and a comparator in communication with the memory and the sensor for comparing the calibration signal to the plurality of fluid pressure signals. The device also preferably includes a plurality of indicators responsive to the comparator for indicating at least two load weight levels. The plurality of indicators include a first load weight level indicator for only indicating when the load weight level exceeds the predetermined load weight limit level and a second load weight level indicator for only indicating when the load weight level is below the load weight limit level.
