PARISIAN MICHAEL L / MADGESON SCOTT

One aspect of the invention relates to a method comprising the steps of:-providing a computer-controlled brake (14) having a first solenoid valve (54) capable of selectively coupling an actuation tube (42) to the atmosphere so as to prevent any pressurization of the actuation tube and subsequent release of the locomotive automatic brake, and a second solenoid valve (64) capable of selectively coupling the actuation tube (42) to the atmosphere so as to prevent any pressurization of the actuation tube and subsequent release of the locomotive automatic brake; the second solenoid valve is able to selectively pressurize the independent application and release tube (44) so as to maintain the applied brake cylinder pressure in the locomotive independent brake and to prevent loss in the locomotive independent brake, characterized by further comprising the steps of:-receiving an operator input indicative of a desired marshalling exchange; and-operating the first solenoid valve using a computer-controlled brake to couple the actuation tube to the atmosphere and operating the second solenoid valve to pressurize the independent application and release tubes, so as to be able to perform a marshalling exchange without risk of rolling. Another aspect of the invention relates to an electronic air brake system configured to perform the method.

本发明的一个方面涉及一种方法，包括以下步骤：‑提供具有第一电磁阀(54)和第二电磁阀(64)的计算机控制的制动器(14)，第一电磁阀能够选择性地将致动管(42)耦接到大气，从而防止致动管的任何加压和机车自动制动器的随后释放，第二电磁阀能够选择性地对独立施加和释放管(44)加压，从而保持所施加的机车独立制动器中制动缸压力，并防止机车独立制动器中的损失，该方法的特征在于还包括以下步骤：‑接收指示期望编组交换的操作员输入；以及‑使用计算机控制的制动器来操作第一电磁阀以将致动管耦接到大气，并操作第二电磁阀以对独立施加和释放管加压，以便因此能够在没有滚动风险的情况下执行编组交换。本发明的另一方面涉及一种电子空气制动系统，其被配置为执行所述方法。
