Title:
自動変速機のパワーオン2-3アップシフト制御方法
Document Type and Number:
Japanese Patent JP4730763
Kind Code:
B2
Abstract:
The system has a transmission control unit (50) controlling a hydraulic pressure control actuator (70) to perform a gear shifting on basis of signals from a sensor. The control unit performs a duty control for controlling hydraulic pressures for an oncoming friction unit and an off-going friction unit during a power-on 2-3 upshift, such that pressures of the friction units are simultaneously controlled based on a turbine torque. An independent claim is also included for a power-on 2-3 upshift control method for an automatic transmission.
