Abstract
In an engine output control apparatus of a power train employing an engine and an automatic transmission, capable of executing engine output control for excessive torque input prevention engine torque limiting action and for a shift speed control of the transmission, at least two different kinds of engine output control systems having control characteristics differing from each other, are provided. A controller selectively uses these engine output control systems depending on a power-train operating condition, such that a first one of the engine output control systems having a superior transient response is used for the engine output control for shift response control during shifting, and that a second one of the engine output control systems having a superior steady-state stability is used for the engine output control for excessive torque input prevention engine torque limiting action during non-shifting.
