Shift control method for automated manual transmission in a hybrid vehicle

摘要

Disclosed is a method for providing a smooth and stable synchronization operation of a transmission achieved in spite of the sudden change of a vehicle speed in the automated manual transmission (AMT) hybrid vehicle that suppresses a collapse of the synchronization by generating a torque by a motor connected to an input shaft in consideration of changes in inertia of the motor and a control target rotational speed during shifting.

1. A shift control method for an automated manual transmission (AMT) hybrid vehicle, comprising:
suppressing, by a controller, a collapse of the synchronization by generating a torque by a motor connected to an input shaft based on a synchronization load torque calculated by multiplying a variation amount of a control target rotational speed of the input shaft by an inertial moment of the motor, wherein suppressing is performed when the synchronization load torque acquired by multiplying the variation amount of the control target rotational speed of the input shaft by the inertial moment of the motor is not 0 after gear engagement has begun at a target shift stage, and wherein suppressing initiates after gear engagement has begun at the target shift stage and when the gear engagement has completed suppressing is terminated.
