摘要：
A control unit of a CVT is provided to produce a basic exciting current for the dither exciting current fed to a solenoid of the solenoid operated control valve. A dither is added to the basic exciting current for producing the dither exciting current. A positive deviation and a negative deviation of the dither exciting current from the basic exciting current in one cycle of the dither is integrated for producing integrals. A correction value which renders the sum of said integrals zero is produced. The correction value is added to the dither so that a corrected dither exciting current is produced.
