Title: Speed change control device for automatic transmission
Inventor: IMAMURA TATSUYA
IPC: F16H61/06
Filed: 2001-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent generation of shock at the time of foot returning upshifting. SOLUTION: In an automatic transmission, a command hydraulic pressure to an engagement device in changing speed is formed of an open control component to decide an inclination based on input torque, and a feedback control component relative to a target gear ratio.
