Abstract

"APARELHO E PROCESSO DE DETECçãO DE PERDA DE UM SINAL DE VELOCIDADE DE VEìCULO EM UM SISTEMA DE DIREçãO ELETRICAMENTE ASSISTIDO, SISTEMA DE DIREçãO ELETRICAMENTE ASSISTIDO E PROCESSO DE CONTROLE DE UM SISTEMA DE DIREçãO ELETRICAMENTE ASSISTIDO". Um sistema de direção eletricamente assistido inclui um sensor de velocidade de veículo que fornece um sinal de velocidade de veículo. Uma determinação é feita quanto à perda do sinal de velocidade de veículo ter ocorrido. O amortecimento do sistema de direção eletricamente assistido é controlado em resposta à velocidade de veículo sentida e em resposta a um valor de velocidade de veículo predeterminado quando o sinal de velocidade de veículo é perdido.
