DISPOSITIVO ELETTRONICO DI ASSERVIMENTO DELLA PRESSIONE PER TRASMISSIONI AUTOMATICHE PER AUTOVEICOLI

摘要

A control generator starting from supplied data relative to the functioning of the transmission and of the motor, supplies a transfer voltage proportional to the line pressure. The control comprises a primary electrical loop containing a pressure tap and a secondary hydraulic loop comprising an electro-hydraulic transducer. The line pressure is thus controlled. The stability and control performance of the transmission are improved by means of electrical correction circuits. The apparatus may be adapted to any desired type of automatic transmission.
