摘要
A system is provided for sensing the presence of a semi-tractor as the mechanical connection between a trailer and a fifth wheel of the semi-tractor is made, or for sensing the presence of a rail car as the mechanical connection between the trailer and a stanchion plate of the rail car is made. A sensor is provided in the floor of the trailer proximate to the kingpin. The sensor senses the presence of the fifth wheel or the rail car stanchion plate during the connection process. Control circuitry on the trailer processes and uses signals from the sensor to perform various functions.
