Control system for both engine and automatic transmission

摘要

A control system for controlling both an engine capable of selecting a plurality of output characteristics having different output torques for a throttle opening and dropping a selected output torque temporarily, and an automatic transmission connected to the engine. The control system comprises: a first decider for deciding it on the basis of data inputted that the output characteristics of the engine should be changed; a second decider for deciding it on the basis of input data including a vehicle speed and a throttle opening that a gear change should be performed; and a third decider for deciding, when the second decider decides the performance, the torque-down to be temporarily effected, to a value according to the output characteristics of the engine.
