Abstract

"SISTEMA DE DIREçãO ELETRICAMENTE ASSISTIDA". Em um sistema de direção eletricamente assistida, o sinal de saída de um sensor de posição de motor elétrico (9) compreendendo um número de dispositivos de efeito Hall (A, B, C) ou semelhantes é combinado com um sinal de índice de um sensor (108) conectado com o eixo da coluna de direção (1) ou a cremalheira (6) ou um sensor de guinada ou outro dispositivo dependente de posição angular para produzir uma medição exata do ângulo de direção em relação à posição para avanço em linha reta. Em um conjunto preferencial, transições na saída de sensor de efeito Hall são usadas para ativar um contador (106) que é reposicionado a zero sempre que o sinal de índice é produzido para assegurar que não sofra deriva através de um período de tempo. Mais convenientemente, o sinal de índice corresponde à posição de avanço em linha reta do mecanismo de direção.
