Wireless data transfer system for a tractor-trailer

摘要

A means of wireless data transmission between a tractor and a trailer using a data transfer system having a first communication unit that is installed on the front of the trailer and a second communication unit that is installed on the rear of the tractor cab. Both communication units on a coupled tractor-trailer are located facing each other across a hitching space between the tractor and trailer to define a communication gap over which data is wirelessly transmitted. A notification device is carried by the tractor and operatively connected to the second communication unit. At least one data collector is carried by the trailer and operatively connected to the first communication unit. Accordingly, the driver is provided with information through the notification device from the data collector by way of the first and second communication unit, which wirelessly transmit the data between the tractor and trailer.
