自動変速機の制御装置
Document Type and Number:
Japanese Patent JP6414571
Kind Code:
B2
Abstract:
An electronic control unit (5) is configured to set a target torque phase time which is used in torque phase control based on an output shaft torque difference. The electronic control unit (5) sets the target torque phase time to be longer when the output shaft torque difference is large than when the output shaft torque difference is small. Accordingly, since the target torque phase time can be appropriately set, it is possible to achieve both of preventing a sudden change in driving force and torsion vibration of an output shaft and preventing a decrease in drivability due to hesitation at the same time. Sudden change in driving force and torsion vibration of the output shaft occur when the difference in driving force between before and after a gear shift is large. Hesitation occurs when the difference in driving force between before and after the gear shift is small.
