Abstract

"MéTODO E DISPOSITIVO PARA DETECçãO DE POSIçãO". A presente invenção se refere a um método para a detecção da posição substancialmente independente de temperatura de um elemento de movimento (9) por intermédio de um sensor de posição indutivo (1), compreendendo uma bobina (5) e um núcleo (4) móvel dentro da bobina, a posição do referido núcleo em relação à bobina (5) sendo dependente da posição do referido elemento (9), por intermédio do que uma medição da indutância da referida bobina (5), correspondendo à posição do núcleo (4), é detectada pela conexão de uma voltagem à referida bobina (5) e medição do período de tempo no qual uma corrente (i) através da bobina (5) é mudada entre dois níveis pré-determinados. A presente invenção é caracterizada por compreender as seguintes etapas: alimentação de uma voltagem alternada regularmente à bobina (5); medição da corrente (i) fluindo através da bobina (5); medição do período de tempo (t~ 1~) necessário para referida corrente (i) mudar a partir de um primeiro nível pré-determinado (i~ 1~) para um segundo nível pré-determinado (i~ 2~); e determinação de uma medição da posição do núcleo (4) através da medição do referido período de tempo (t~ 1~). Através da presente invenção, uma detecção de posição aperfeiçoada é proporcionada, principalmente intencionada para caixas de marchas de veículos automotivos, conseguindo uma dependência de temperatura altamente reduzida.
