Abstract

Lately, the high performance solenoid valve is adopted to hydraulic control system for hydraulic pressure control in automatic transmission. But it is difficult to obtain the performance control performance that reflects the performance of solenoid valve characteristic sufficiently from conventional valve and the redesign is needed for the better hydraulic control system This paper proposes process of the pressure control vade design that is based on the pressure control characteristic of solenoid valve. And the characteristic of designed pressure control valve is confirmed by simulation program analytically, As a result it is possible to save time and effort for development in early stage and tn reduce a test step efficiently. Finally, pressure control characteristic of valve that is designed with proposed design process in this study compared with experiment results And it shows that the experimental result satisfies a design target considerably with good agreement.
