摘要

A control device for an internal combustion engine (E) and a continuously variable transmission (35) according to the invention is provided at a power transmission system (P) between the internal combustion engine (E) mounted on the automobile and driving wheels (32), in which device a gear ratio is continuously switch controlled at a predetermined gear change speed (Vm) so that an engine speed ( omega e) and a vehicle speed (Vc) can maintain a gear ratio (in) which is suitable for a vehicle driving condition, and the output of the internal combustion engine (E) can also be controlled. The control device for the internal combustion engine (E) and the continuously variable transmission (35) sets a gear change speed (Vm) on the basis of a deviation ( DELTA i) between a target gear ratio (io) and an actual gear ratio (in), whereby a continuously variable gear ratio (35) is controlled by the gear change speed (Vm), while the output of the internal combustion engine (e) is controlled by a gear change assisting torque ( DELTA Te) corresponding to the gear change speed (Vm), whereby slippage of the continuously variable transmission (35) and shock resulting from a gear change are reduced.
