Target Volume Based Shift Controls with High Flow PWM Solenoids 2010-01-0369

The Chrysler Ultradrive four-speed transaxle 41TE was the first production transmission to pioneer fully adaptive direct clutch-to-clutch electronic controls without overrunning clutches. "Single stage" high flow PWM solenoids have been used for transmission control since 1989 and still being used in the later-developed 545RFE and 62TE transmissions. The proposed target volume-based shift control method allows the usage of flow-based control device such as PWM solenoids to implement torque-based control strategy. Vehicle test results with this new method have shown excellent shift quality and improved system consistency.
