This paper proposes a control solution for a vehicular driveline with an internal combustion engine, a continuously variable transmission and an additional flywheel unit. This unit plays a part only in transient situations. It compensates for the engine inertia, enabling optimal fuel economy in stationary situations without losing driveability during transients. For control design, a simple, nonlinear model is developed and used for feedback linearization. The proposed controller is evaluated by simulations, using an advanced simulation model. The compensation of the engine inertia by the additional flywheel is demonstrated by vehicle experiments.
