This paper describes an approach to investigate and develop a model and controller of CVT (Continuous Variable Transmission) Electro – mechanical Clutch for automotive application. The vehicle dynamic driveline is developed based on a medium size vehicle with CVT Transmission integrated with an electro – mechanical clutch for generation of the controller. The modeling inputs consist of the engine torque (Nm) at certain speed (RPM) and the torque load (Nm) which is used to sense the required Clamp Force (FC) to be acted on the clutch for engagement process. The model considers the vehicle start from stop phase. A Proportional Controller (P-Controller) is proposed and numerical results shows it is able to provide smooth and comfort clutch engagement process at any engine speed.
