Abstract
Method and apparatus for providing self-contained brake release capabilities in a tractor trailer to facilitate autonomous movement of the trailer within a controlled environment such as in a yard, depot or other facility. Pressurized air is stored in a reservoir of the trailer while the trailer is in a stationary, parked position. Upon receipt of a wirelessly transmitted brake release command, a trailer controller circuit transitions a flow valve to interconnect the reservoir to a brake assembly to apply pressure sufficient to release the brake assembly and enable rolling movement of a wheel assembly of the trailer. In this way, a yard shifter or other transport vehicle can mechanically engage and move the trailer without the need to provide pressurized air or electrical power to the tractor trailer in order to release the brakes. Security protocols can be used to ensure the brake release operation is performed under authorized conditions.
