Abstract:
An electronically controlled pneumatic (ECP) overlay control valve can selective switch between a conventional pneumatic mode and an ECP mode. In ECP mode, the overlay control valve shunts the brake cylinder pressure of the pneumatic control valve which allows a relay valve to build or exhaust pressure in the brake cylinder in response to an electronically controlled apply/release circuit. In conventional pneumatic mode, the overlay control valve disconnects the relay valve and allows a conventional pneumatic control valve to control the pressurization and exhausting of the brake cylinder.

Claim (Index 6):
A method of providing for electronically controlled pneumatic brakes in a conventional pneumatic braking system having a brake cylinder pressure outlet, comprising the steps of\n operating a relay valve having a first port coupled to a source of reservoir pressure, a second port for providing a brake cylinder pressure output, and an exhaust, wherein the relay valve is movable between a first position where the second port is connected to the exhaust, a second position where the first port, the second port, and the exhaust are isolated from each other, and a third position where the first port is connected to the second port so that the source of reservoir pressure provides the brake cylinder pressure output. coupling the second port of the relay valve to the brake cylinder pressure outlet using a pilot valve that is moveable in response to pressure at a pilot between a first position where the second port of the relay valve is coupled to the brake cylinder pressure outlet and a second position where second port of the relay valve is isolated the brake cylinder pressure outlet.
