Abstract

trata-se de um método e um sistema para detecção de desvios de torque de um motor (101) em um veículo (100). de acordo com o método, é feita uma medição (201) de valores medidos reais dact relacionados a um comportamento de pelo menos um parâmetro que é relacionado a um torque real meng_act entregue pelo motor (101). esse torque real meng_act é entregue aqui pelo motor (101) em consequência de um torque meng_req demandado pelo motor (101). é feita, então, uma comparação (202) dos valores medidos reais dact que são relacionados ao comportamento do pelo menos um parâmetro com valores medidos previamente determinados dref de correspondentemente pelo menos um respectivo parâmetro relacionado ao torque real meng_act. os valores medidos previamente determinados dref terão sido aqui determinados durante a operação normal do veículo (100). é feita, então, uma detecção em relação a se o torque real medido real meng_act desvia do torque demandado mengj-eq. a detecção é baseada aqui na comparação dos valores medidos reais dact com os valores medidos previamente determinados dref.
