Methods and system for improving hybrid driveline operation
Abstract:
Systems and methods for improving transmission gear shifting of a hybrid vehicle are presented. The systems and methods prepare the hybrid vehicle for conditions that may occur after a requested gear shift is performed. In one example, a motor speed that would occur after a downshift, if the downshift were allowed to occur, is determined and control actions may be taken in response to the predicted motor speed.
