Method and apparatus to create a pseudo torque phase during oncoming clutch engagement to prevent clutch slip for a hybrid powertrain system |
摘要 |
A method for controlling a powertrain comprising an electro-mechanical transmission (10) mechanically-operatively coupled to an engine (14) and an electric machine (56,72) adapted to selectively transmit mechanical power to an output member (64) through selective application of a plurality of torque-transfer clutches (70,62,73,75) includes monitoring a clutch slip speed, synchronizing an oncoming clutch, and constraining reactive clutch torque limits for the oncoming clutch to achieve a reactive clutch torque that is less than an estimated clutch torque capacity. |
