Abstract
"MéTODO E SISTEMA PARA CONTROLE DE TROCA DE MARCHA ADIANTE DE TRANSMISSãO AUTOMATIZADA ADPTáVEL". Um método/sistema para controlar troca de marcha adiante em um sistema de transmissão mecânica automatizada (10) utilizada em um veículo. Quando uma troca de marcha adiante a partir de uma relação de marcha atualmente engatada (GR) é requerida (ES > ES~ U/S~), trocas de marcha adiante de salto (GR~ ALVO~ = GR + N, N > 1) e então trocas de marcha adiante simples (GR~ ALVO~ = GR + 1) são avaliadas em seq³ência. Se a demanda do acelerador for alta (THL > REF) encorajar seleção de relações de marcha orientada para desempenho, trocas de marcha adiante de salto são avaliadas para determinar se elas podem ser completadas em uma velocidade de motor mais alta (ES~ MIN~ = ES~ PADRãO~ + deslocamento) que é de outro modo requerido.
