ABSTRACT:
A shift shock reducing apparatus installed in a vehicle which is equipped with a power train constituted by a continuously variable transmission (CVT) and an engine. The shift shock reducing apparatus comprises a calculating section which calculates an inertia torque caused by a shifting from a rate of change in a CVT ratio per time and an output torque correcting section which corrects a toque inputted to the CVT on the basis of the calculated inertia torque so as to cancel the inertia torque. Therefore, shift shocks due to the inertia torque is suppressed without generating a shift delay.
