Method for controlling neutral modes in a multi-mode hybrid transmission |
摘要 |
A method of clutch control includes engaging a first holding clutch to place the transmission in a first neutral mode and predicting a first EVT mode. The method begins tracking a first output clutch and predicts a second EVT mode. Tracking the first output clutch ends and tracking a second holding clutch begins. The method engages the second holding clutch to place the transmission in a second neutral mode, ending tracking of the second holding clutch. The first holding clutch is disengaged to place the transmission in a third neutral mode and the method begins tracking a second output clutch. Engaging the second output clutch places the transmission in the second EVT mode and ends tracking of the second output clutch. The engine may be placed into a speed control mode and the transmission placed into a full hydraulic neutral mode. |
