摘要： PROBLEM TO BE SOLVED: To reduce engagement-side transmission hydraulic pressure to prevent degradation of transmission quality when release of lock-up is predicted during down-shift in a coast lock-up state.SOLUTION: When a vehicle is coasting and an accelerator opening degree APO is zero, or when a torque converter is locked up so as to increase fuel cut time, a down-shift command is issued at the time t1. While an automatic transmission is shifted down by reduction in release-side clutch hydraulic pressure Poff and increase in engagement-side clutch hydraulic pressure Pon, the engagement-side clutch hydraulic pressure Pon is reduced, as shown in a part C of a dashed-dotted line, after the time t2 where lock-up release is predicted, from higher lock-up ON hydraulic pressure to lower lock-up OFF hydraulic pressure as shown by a broken line. The draw of transmission output torque is prevented from being increased at the start of an inertia phase t5, and subsequent changes D in vehicle deceleration G are kept small as shown by the dashed-dotted line, thereby improving transmission quality.
