Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA O COMANDO DE UM ATUADOR CAPACITIVO"<D>. A um atuador capacitivo é conduzida uma energia (E) e a tensão do atuador (Up) adjacente ao atuador é medida. A partir da energia (E) e da comparação da tensão do atuador (Up) com valores de referência (Bo; Bu) são feitas conclusões sobre um estado de funcionamento, por exemplo, falha ou funcionamento correto do atuador, ou de uma válvula de injeção. Além disso, da tensão do atuador (Up) são feitas conclusões sobre um curso do atuador (ds). Ao processo cabem as regularidades mostradas em um diagrama com curvas características do atuador KL I; KL II).
