Abstract

Patente de Invenção: <B>"MéTODO PARA MINIMIZAR UMA DESATIVAçãO INDESEJáVEL DE FREIO"<D>. Trata-se de um método e um sistema para minimização de afrouxamento indesejável de frenagem no sistema de freio de um trem possuindo um freio pneumático em cada vagão ligado a um tubo de freio que é controlado por um dispositivo controlador de tubo de freio. O método inclui a determinação do estado do sistema de freio de princípio a fim do trem e a determinação de uma redução mínima do tubo de freio para o dispositivo controlador de tubo de freio, utilizando o estado do sistema de freio. A redução mínima de tubo de freio determinada é exibida por si mesma ou em combinação com a redução de tubo de freio produzida pelo dispositivo controlador de tubo de freio.
