In case a primary hydraulic pressure sensor is normal, when reverse rotation of pulleys is detected a primary pulley (Plpri) torque capacity is calculated from a primary pressure detected by the primary hydraulic pressure sensor. When the primary hydraulic pressure sensor fails, a secondary hydraulic pressure sensor is checked, and when the secondary hydraulic pressure sensor is normal, the PLpri torque capacity is determined from a secondary pressure detected by the secondary hydraulic pressure sensor by using a map. On the other hand, when the secondary hydraulic pressure sensor fails too, the PLpri torque capacity is read out from the map by using a secondary pressure target value as the secondary pressure. |
