To improve engine torque estimation accuracy based on a detection value of an air intake quantity sensor.
A first engine torque estimation value rTq1 is calculate based on a detection value rQa1 of an airflow meter 18. An air intake quantity correction unit B2 corrects the detection value rQa1 of the airflow meter 18 to a post-correction value rQa2 based on a detection value rA/F of an air-fuel ratio sensor 9. An engine torque estimation unit B3 selects the greater value from among the first engine torque estimation value rTq1, which is based on the detection value rQa1 before correction, and a second engine torque estimation value rTq2, which is based on the post-correction detection value rQa2, as a final engine torque estimation value rTq to be used in setting a belt oil pressure between a belt and a pulley of a belt-type continuously variable transmission.
