Abstract

a presente invenção refere-se a um primeiro método para calibrar um sensor de corrente (4) que é configurado para determinar, em um sistema de alimentação de bordo (2) de um veículo, uma corrente de funcionamento elétrica (12) que flui através de um resistor de medição (20), com base na comparação (38) de uma queda de tensão no resistor de medição (20) causada pela corrente de funcionamento (12) e com base em uma regra (21) que é dependente do resistor de medição (20), que compreende: determinar uma queda de tensão de operação (22) provocada no resistor de medição (20) pela corrente de funcionamento (12); gravar uma corrente de calibração elétrica conhecida (40) no resistor de medição (20), detectando uma queda de tensão global (4) provocada pelo resistor de medição (20) pela corrente de calibração (40) e pela corrente de funcionamento (12), - filtrando a queda de tensão de operação (22) a partir da queda de tensão global (42), com o resultado de que uma queda de tensão de calibração (44) provocada pela corrente de calibração (40) permanece, e calibrar (58) a regra (21), dependente do resistor de medição (20), com base na comparação (57) da corrente de calibração (40) e da queda de tensão de calibração (42).
