Abstract
In a system for controlling the output power of a power train an overall control is carried out so that a mismatch is not caused between the output characteristic changeover control of a variable output characteristic engine and the speed change control of an automatic transmission. From the requested driving force and the revolution speed that are respectively found by the requested driving force detection device and the speed detection device the control output determination device finds a combination of at least two of the engine output characteristic, the speed change stage and the engine throttle opening according to the two dimensional map of the requested driving force and the revolution speed, and the changeover executing device conducts total control on the power train so that the combination can be attained. When the power train is controlled totally as the combination, a mismatch between the changeover control of engine output characteristics and the speed change control can be avoided.
