Abstract
a presente invenção refere-se a um método para proporcionar um sistema de controle de alta dirigibilidade para um veículo agrícola ou industrial (10) que tem um motor (40) e a transmissão continuamente variável (cvt) (60) inclui ajustar um alvo de velocidade máxima (mst) (30), e ajustar um percentual de velocidade do veículo (vsp) (32) de acordo com a entrada usando a entrada de velocidade desejada (38). a velocidade alvo do motor (42), um coeficiente alvo de mudança (52) da velocidade do motor (42), a relação de cvt alvo (74), e um coeficiente alvo de mudança (88) da relação de cvt alvo (74) são então calculados a partir da vsp (32), da mst (30), e da presente velocidade do motor (90). a velocidade alvo do motor (42) pode ser adicionalmente calculada a partir da velocidade do veículo presente (80) e/ou a relação de cvt presente (86).
