EF-automatic transmission is recently developed by Mitsubishi Motor Company and equipped with full electronic control system. Its major design features are that clutch-to-clutch shifting mechanism for simplified construction and lighter weight and four indepen-dently operated PWM solenoid valves control the applying pressure on the friction elements during shift. However, since flow control characteristic of the solenoid valve itself is not enough to meet the required pressure dynamics for shifting control, second stage pressure control valve for each solenoid valve is designed in order to amplify the control flow. Besides, for each control element, there is a accumulator to get rid of the ripple pressure due to the low carrier frequency of PWM driving circuit. Hence, in view of these aspects, hydraulic control system have complicated design with many elements.
In this paper, EF-automatic transmission was redesigned with proportional control solenoid valves of which control pressures are directly applied to control elements and modified transmission with these solenoids was tested on transmission dynamometer to investigate its shifting characteristics. For shifting control algorithm, we adopted open-loop control method during torque phase which is based on the static torque analysis of the power train and closed-loop control algorithm during inertia phase. We designed a turbine acceleration feed-back controller with considering the linearized turbine dynamics model and implemented the shifting algorithm with a microprocessor. From the simulated and experimental result, we concluded that proportional control solenoid valves have acceptable flow capacity for auto-matic transmission shifting control and proposed control algorithm shows good shifting per-formance
