Abstract

a presente invenção refere-se um sistema de controle de freio pneumático de locomotiva que responde a pedidos de frenagem de emergência provenientes dos sistemas externos aplicando uma quantidade variante de nível de freio de trem com base em parâmetros monitorados e calculados de modo a forçar uma condição definida para o trem. o sistema pode incluir uma frenagem de trem mínima aceitável, uma condição a ser atingida para impedir aplicação adicional dos freios do trem, e um nível máximo de freio de trem a ser aplicado em resposta a um pedido. de maneira alternativa, o sistema pode aplicar frenagem em níveis escalonados de acordo com os limites definidos para uma variante de comportamento do trem de interesse, tal como velocidade ou desaceleração. o sistema pode ser configurado para aplicar e liberar de forma incremental os freios do trem durante uma frenagem de emergência adaptativa e também pode ajustar o nível de frenagem de acordo com a capacidade de frenagem calculada do trem.
