SHIFT CONTROL METHOD OF AMT HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a shift control method of an AMT hybrid vehicle which prevents a fault in gear engagement even if there arises an abrupt change in vehicle speed in the AMT hybrid vehicle, improves drivability by minimizing a power interruption state by quick gear engagement, and improves the durability of a transmission.;SOLUTION: The shift control method of the AMT hybrid vehicle includes an active synchronization maintaining stage which suppresses a collapse of the synchronization by generating torque by a motor by taking into consideration the inertia of the motor connected to an input shaft during shifting, and a change of a control target rotation speed of the input shaft. On and after gear engagement to the target shift stage is started, the active synchronization maintaining stage is implemented when synchronous load torque which is obtained by multiplying a change amount of the control target rotation speed of the input shaft with the inertia moment of the motor is not zero, and the torque generated by the motor is the synchronous load torque in the active synchronization maintaining stage.;COPYRIGHT: (C)2013,JPO&INPIT
