Abstract

Patente de Invenção: <B>"SENSOR DE âNGULO DE DIREçãO ABSOLUTO ADAPTATIVO"<D>. A invenção refere-se a um sensor de ângulo de direção absoluto adaptativo para a determinação absoluta de um ângulo de giro, especialmente, para a determinação do ângulo de direção em um veículo motor por meio de um código aplicado através de uma faixa angular de 360° para determinação do ângulo. O código e um sistema sensor são dispostos de forma que sejam capazes de girar um em relação ao outro. A determinação absoluta do ângulo é realizada pela leitura da informação de contraste usando-se um microprocessador, o qual determina a posição angular do código e a resolução fina dos ângulos com base na posição relativa do ângulo reconhecido para a imagem no sistema fotodetector. Ao mesmo tempo, o funcionamento geral do sistema é verificado e ajustado durante cada medição. O código é determinado usando-se um sistema fotodetector, posicionado em um único local, e usado para a determinação do ângulo, por meio do que um segmento não-partido da trilha de código é mostrado em pelo menos uma linha fotodetectora e pelo menos uma palavra de código é determinada, a qual corresponde a um ângulo predeterminado. A posição da palavra de código em relação à posição fixa da linha fotodetectora é medida.
