Abstract:
A transmission controller detects a rotation speed of an input shaft, calculates an inertia torque input to a continuously variable transmission based on a change ratio of the detected rotation speed, obtains a positive inertia torque by extracting a positive portion from the calculated inertia torque, and corrects pulley pressures based on the extracted positive inertia torque.
