A METHOD AND APPARATUS FOR SIMULATING A FAILED HEAVY VEHICLE AIR BRAKE SYSTEM

摘要

A method and apparatus for simulating a failure in a heavy vehicle airbrake system where a failure initiation switch is connected to a failed systemselector switch and both switches are connected to a first valve associatedwitha primary braking system and a second valve associated with a secondarybraking system of a vehicle. The failure initiation switch and the failedsystemselector switch are used to selectively interrupt a braking signal to eithersaidprimary braking system or said secondary braking system.
