Abstract
A continuously variable transmission ( ) is provided with: an endless transmission ( ) for transmitting a driving torque; a clamping force ( - - ) coupled with the endless transmission ( ) for applying a clamping force thereon; a controller ( ) coupled with the clamping force ( ) for influencing the driving torque by controlling the clamping force applied on the endless transmission ( ); and a clutch ( ) coupled with the controller ( ), whereby the controller ( ) is arranged to control the clutch such that the clutch ( ) is allowed to slip continuously. The net effect of a practical implementation of the transmission in a vehicle is a fuel saving which, if a slip of around 5 rpm is permitted, amounts about 3-4%.
