Abstract

resumo "método para avaliar torque a jusante de uma transmissão de veículo" a presente invenção se refere a um método para avaliar torque (t, h) trans-mitido para uma estrutura (32) situada a jusante de um sistema de transmissão (1) de um veículo, o veículo compreendendo um motor (2) para gerar torque (m), o sis-tema de transmissão (1) sendo configurado para transmitir uma fração (w) do torque (m) gerado pelo motor (2) para uma pluralidade de rodas (3) do veículo e uma fração adicional (t + h) de torque (m) gerado pelo motor (2) para a dita estrutura (32), o sistema de transmissão (1) compreendendo: uma disposição de eixo (12) interposta entre o motor (2) e a dita estrutura (32); uma engrenagem planetária (22) suportada pela disposição de eixo (12); uma unidade de transmissão (5) disposta em paralelo à disposição de eixo (12); em que o torque (t; h; w) transmitido para a dita estrutura (32) é avaliado com base em um grupo de parâmetros que compreende: torque (m) contra a corrente do sistema de transmissão (1); guinada (??) da disposição de eixo (12); um parâmetro (?) que é indicativo da proporção entre um velocidade rotacional de saída em uma saída da unidade de transmissão (5) e uma velocidade rotacional de entrada em uma entrada da unidade de transmissão (5).
