PURPOSE:To facilitate a delicate change gear ratio control by correcting the operated gear change actuator displacement amount to make the variation speed of the change gear ratio in a linear relation, and outputting the corrected displacement amount to a displacement actuator. CONSTITUTION:The rotation speed of an input rotation shaft 12 is detected by a sensor 26, and the result is input to an input disk rotation speed correcting value operation device 28. Then, the tilting angle of a tilting shaft 22 is detected by a sensor 30, and the result is input to a tilting angle correcting value operation device 32 and a power roller rotation speed correcting value operation device 34. The correcting values are operated by the correcting value operation devices 28, 32, and 34 respectively, and the results are output to a speed change instruction value correcting device 36. The speed change instruction value correcting device 36 operates the displacement amount DELTAY1 of the tilting shaft 22, and the correcting displacement amount DELTAY2 depending on the input correcting values. The displacement actuator 24 is operated by this corrected displacement amount DELTAY2, so as to displace the tilting shaft 22. |
