Abstract
A brake control signal amplification system that is designed to assist with the compliance to the FMVSS-121 Safety Standard for an air braked vehicle is described which comprises a trailer control module (TCM) that provides pneumatic signal to a trailer of the vehicle, a tractor protection valve (TPV) that protects a tractor air brake system in the event of a pneumatic disconnection from the trailer, and a pilot relay valve (PRV) coupled between the TCM and the TPV, wherein the PRV amplifies a control signal received from the TCM and delivers an amplified control signal to the to the TPV. The TPV delivers the amplified control signal to a control coupling for a trailer portion of a vehicle and delivers an air supply to a supply coupling for the trailer of the vehicle.
