  • Patent number: 9464715
    Abstract: While a vehicle is decelerating starting at a braking start time, start-off pre-shifting starts when speed falls to a predetermined speed. At a vehicle stoppage time, an idle stop permission flag is not set to on if start-off pre-shifting is incomplete, even if idle stop permission conditions have been met. The idle stop permission flag is set to on when start-off pre-shifting is completed, and an idle stop flag is set to on and the engine stopped when engine rotational speed falls below a set speed. The engine is restarted in response to braking being released, and the idle stop flag is set to off and the idle stop control ended when the engine rotational speed reaches or exceeds a set speed. The restarting of the engine causes an engine-driven oil pump to dispense oil to be used as a medium to manifest an automatic clutch command hydraulic pressure.

  • Patent number: 9340196
    Abstract: Under a specified condition where a torque converter is kept in a lockup state to prolong the fuel-cutoff time, because of vehicle coasting with an accelerator opening APO=0, a downshift command is generated and then an automatic transmission causes a reengagement downshift by a drop in a release-side clutch hydraulic pressure Poff and a rise in an engagement-side clutch hydraulic pressure Pon. During the reengagement downshift, the engagement-side clutch hydraulic pressure Pon is reduced from a high lockup-ON hydraulic pressure to a low lockup-OFF hydraulic pressure after the time when the lockup is predicted to be released, thus preventing a torque drawing-in tendency of transmission output torque, which may occur at the time of the beginning of the inertia phase, from increasing, and also reducing in the width of a subsequent change in vehicle deceleration G, and consequently enhancing the shift quality.
