PROBLEM TO BE SOLVED: To relieve a sudden torque fluctuation by decreasing the output of an internal combustion engine by a torque down means during designated time when switching the change response from the quick state to the slow state. SOLUTION: A rotating speed from an engine rotating speed sensor, a car speed signal from a car speed sensor 302, and a throttle opening from a throttle opening sensor 303 are read, and according to these inputs, a target gear ratio generating device 500 operates an attained gear ratio, a target gear ratio and the actual gear ratio. Subsequently, from these gear ratios, a gear ratio servo device 510 outputs a pulse control signal SS/ M for controlling a target step motor. An ignition timing lag value generating device 515 outputs an ignition timing lag signal SRE for conducting the torque down control for an engine from the attained gear ratio and the target gear ratio. When the signal SRE is input to the engine control unit, an ignition lag amount is output from the unit so that the ignition timing is made lag and the output torque is lowered. |
