Abstract: A smart trailer system coupled to a trailer of a vehicle includes a sensor configured to measure a parameter of the trailer, a sensor interface board electrically coupled to the sensor and configured to retrieve the measured parameter, and a master controller communicatively coupled to the sensor interface board via a data bus.

Abstract: A system and method is provided to lock or unlock a gladhand coupler on a towed asset to prevent connection of a tractor air line to the gladhand is provided. The system prevents the tractor from properly operating the towed asset brakes and therefore prevents the unauthorized movement of the towed asset. The system has a locking mechanism that blocks the surface on the gladhand used for coupling with another gladhand coupler.
