Abstract
A control system for an engine-CVT drive train controls engine torque change against inertia torque that would take place during ratio change due to inertia attached to the CVT input shaft. A target speed is computed from operator power demand and vehicle speed. A target ratio is computed from the target speed and vehicle speed. A ratio command is computed from the target ratio. The control system computes the inertia torque from the ratio command or the target ratio.
