Abstract
"MéTODO DE EFETUAR A MUDANçA DE MARCHA DE UMA TRANSMISSãO AUTOMáTICA". Um método é apresentado de efetuar a mudança de marcha de uma transmissão automática em um veículo tendo um motor controlado por uma unidade de controle de transmissão eletrónica. Durante uma mudança a transmissão de mudança automática tem uma embreagem que sai e uma embreagem que entra. O método inclui determinar uma pressão de patinagem que sai predita para a embreagem que sai e determinar uma pressão de patinagem que entra predita para a embreagem que entra, ambas em função da carga de motor. A pressão de patinagem que sai predita é uma pressão à qual a embreagem que sai principiaria a patinar e a pressão de patinagem que entra é uma pressão à qual a embreagem que entra principiaria a transmitir torque. Subseqüentemente, o método inclui rapidamente reduzir a pressão de embreagem que sai, P-off, uma pressão que é ligeiramente mais alta que a pressão de patinagem que sai predita, e rapidamente aumentar a pressão de embreagem que entra P-on a uma pressão que é ligeiramente inferior à pressão de patinagem que entra predita. A seguir, o método inclui gradualmente decrescer P-off e gradualmente aumentar P-off até a patinagem da embreagem que sai ser detectada e gradualmente e mais lentamente decrescer P-off até a embreagem que entra principiar a conduzir torque previamente conduzido pela embreagem que sai. Finalmente, o método inclui mais rapidamente decrescer P-off à pressão do reservatório, e mais rapidamente elevar P-on a uma pressão plena.
