PURPOSE: To enable operation in the most high efficient operating area by computing an accelerator opening signal and a speed signal and controlling change gear ratio and fuel supply so that those formed data may be positioned on an operating line set beforehand.
CONSTITUTION: An arithmetic circuit 3 is provided to control a fuel injection valve, an electromotive actuator and a pulley actuator (a change gear ratio controller). An accelerator opening sensor and a speed sensor are also provided. The change gear ratio controller is controlled based on detected signals from the accelerator opening sensor and the speed sensor in such a way that those operation data may be positioned at an operating point on an operating line set beforehand in the arithmetic circuit 3. A this point, this opening line shall be considered a characteristic curve related to axial torque, which passes through a high axial torque area of low engine speed, and to the engine speed. By this, an operating area, where the engine speed is low and engine axial torque is high, may be available.
