  • Patent number: 8818654
    Abstract: 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.
