ABSTRACT:
A theoretical torque transmitted through a belt is calculated, and a first guaranteed torque is calculated by adding a marginal torque to the theoretical torque. In step S101,the theoretical torque is multiplied by a safety factor, calculating a second guaranteed torque. The second guaranteed torque is set to a value greater than a lower limit value. A smaller one of the first guaranteed torque and the second guaranteed torque is stored in a buffer, and a pressing force calculation reference torque is set through the buffer.
