    摘要： A vehicle has an engine (1) as a driving source. Output rotation of the engine (1) is transmitted to driving wheels (7) through a torque converter (2) equipped with a lock-up clutch, a first gear train (3), a transmission (4) formed by combination of a variator (20) and an auxiliary transmission (30), a second gear train (5) and a final speed reduction device (6). The second gear train (5) is provided with a parking mechanism (8) that mechanically locks an output shaft of the transmission (4) so that the output shaft of the transmission (4) cannot rotate during parking of the vehicle. A shift speed when down-shift is performed by the variator (20) during a torque-down request to the engine (1) is set to be slower than a shift speed when down-shift is performed by the variator (20) during a non-torque-down request.

    摘要： Engine output control apparatus has shift range detecting section detecting shift range of automatic transmission; vehicle speed detecting section detecting vehicle speed; engine output state detecting section detecting engine output state; and controller. The controller performs (a) judgment control judging that torque converter is in a stall state if following judgment conditions (i) to (iii) are satisfied, (i) shift range is drive range, (ii) vehicle speed is equal to or less than predetermined vehicle speed, (iii) engine is in a high output state, (b) cumulation control cumulating a period of agreement of the judgment conditions if the judgment conditions are satisfied, and (c) output suppression control suppressing output of the engine if a control start condition is satisfied by cumulation of the agreement period. The control start condition is set so that as the vehicle speed becomes higher, start of the output suppression control is more delayed.

    摘要： A control device for a lock-up clutch includes a control unit, an abnormality determination unit, a release control unit and a prohibition unit. The control unit is configured to control an engagement state of a lock-up clutch, and to perform a slip lock-up control by performing a feedback control of an engagement hydraulic pressure to be a first slip amount during coasting. The abnormality determination unit is configured to determine an abnormality when a state continues with a slip amount being equal to or greater than a second slip amount. The release control unit is configured to release the lock-up clutch when the abnormality is determined. The prohibition unit is configured to allow the control unit to raise the engagement hydraulic pressure by a prescribed pressure, and to prohibit determination by the abnormality determination unit, when the transmission ratio is downshifted during coasting while the slip lock-up control is performed.
