Continuously Variable Transmission vehicles have been around since the turn of the century. The coordination between the engine and transmission has always been controversial. Many techniques have been proposed from a simple constant engine speed policy to a policy which attempts to make the engine operate at its best efficiency for any power output. These techniques are compared and developed by computer simulation with respect to performance and fuel economy. Implications on engine design are discussed.
