UP-SHIFT CONTROL IN AN AUTOMATIC TRANSMISSION WITH NEGATIVE INPUT TORQUE |
摘要 |
A transmission control module including a shift control module that generates an enable signal when an up-shift is requested and the engine torque is below a threshold torque value. A turbine speed profile determination module that selectively generates a desired turbine speed profile. The shift control module controls a clutch pressure of an off-going clutch based on a measured turbine speed and the desired turbine speed profile when the enable signal is generated.
