Abstract
The Continuously Variable Transmission (CVT) concept has been available for many years. Reliability, durability, efficiency and controllability have been problems in the past. All but controllability have been greatly improved recently. This paper outlines the special control considerations necessary in CVT system design. Stressed is the concept of ideal engine operation and independent operation of engine and transmission control systems.
