Abstract

"MéTODO PARA DETECTAR FALSO NEUTRO E SISTEMA PARA CONTROLAR REDUçãO DE MARCHA EM UM SISTEMA DE TRANSMISSãO AUTOMATIZADA". Um método e sistema para controlar redução de marcha em um sistema de transmissão mecânica automatizada (10) utilizado em um veículo. Quando uma redução automática de marcha de potência a partir de uma relação de marcha correntemente engatada (GR) for requerida, a aceleração do motor (EA) é monitorada e comparada com uma aceleração livre do motor (FEA) para detectar uma falsa condição de Neutro e para adotar ação apropriada de acordo. Alternativamente, uma falsa condição de Neutro é detectada quando o Valor Absoluto da velocidade rotacional do eixo de saída (OS) vezes a relação de marcha correntemente engatada (GR) menos a velocidade rotacional do eixo de entrada (IS) for menor que um valor predeterminado (ABS * GR) - IS).
