摘要： A vehicle transmission system and method of controlling a vehicle transmission are provided that control clutch temperatures to extend clutch life. The system is comprised of an input drive shaft configured to be driven by an engine, an output drive shaft configured to drive a drive mechanism and a plurality of torque-transmitting devices connecting the input drive shaft to the output drive shaft and configured to engage and disengage to provide a transition between a plurality of operating ratios. The system is also comprised of a control module configured to calculate a temperature of the plurality of transmitting devices based at least in part upon a shifting status of the plurality of transmitting devices. The control module is further configured to conduct at least a first modification if the temperature is greater than a first predetermined temperature and a second modification if the temperature is greater than a second predetermined temperature.

摘要： A control system for a hydraulically-operated transmission for a vehicle is disclosed. The transmission is connected to a crankshaft of an internal combustion engine and having a plurality of friction engagement elements. A working oil temperature of the transmission, a cooling water temperature of the engine, and an operating condition of the transmission are detected. An estimated value of the working oil temperature is calculated on the basis of the detected cooling water temperature and the detected operating condition of the transmission. A weighting factor is calculated according to the detected working oil temperature. A weighted average value of the working oil temperature and the estimated working oil temperature is calculated as an actual working oil temperature by using the weighting factor. A hydraulic pressure of the working oil is controlled according to the actual working oil temperature.
