11548491 · 2023-01-10 · ·

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.

Onboard system and emergency brake control method

Upon detecting a current balise, an onboard system of a train calculates a speed curve based on measured traveling speed at a timing of the detection and sets a minimum required time period for traveling to each of a next balise and a balise subsequent to the next balise. Upon detecting the next balise, the onboard system compares a traveling time period from the timing of detecting the current balise to the timing of detecting the next balise with the set minimum required time period. The onboard system activates an emergency brake when the elapsed time period is shorter than the minimum required time period to stop the train.
