Abstract

"SISTEMA DE DIREçãO ASSISTIDO POR ENERGIA ELéTRICA". é descrito um sistema de direção assistido por energia elétrica, que compreende um eixo de direção conectado em uma extremidade ao volante manual e em sua outra extremidade a pelo menos uma roda de estrada, enquanto um motor elétrico é conectado á direção, uma caixa de engrenagens tendo uma relação de engrenagens de redução não-inteira. Dois sensores são também fornecidos, com um medindo a posição angular do rotor de motor e o outro medindo a posição angular do eixo de direção. A presença da relação de engrenagens não-inteira produz uma freq³ência de batimento entre a saída dos dois sensores, pela qual uma medição não-ambígua da posição angular do eixo de direção, em uma faixa maior do que uma revolução completa, pode ser feita. Os sensores podem compreender sensores de posição absoluta ou sensores de tipo de índice.
