ELECTRONIC CONTROL FOR FLUID PRESSURE BRAKING SYSTEM

摘要

A fluid pressure braking system includes pressure sensors in each of the supply and service reservoirs and in the supply line to the trailer. The system includes an air compressor which is loaded and unloaded in response to variations in the pressure level in the supply reservoir by actuation of a solenoid valve by an electronic control module which is responsive to the pressure sensors. The system includes spring brakes which are controlled by the control module through actuation of solenoid valves. The control module is similarly responsive to supply line pressure and the pressure level in the supply line to control a solenoid valve which controls communication through the supply line.
