Two structural forms of continuously variable transmission（CVT）with electronic actuation control scheme are presented based on the working principle of CVT with electronic actuation on basis of the working principle and characteristics analysis of the current belt-type CVT speed ratio control system.The current situation and development trend of CVT control studies are analyzed and the research on integrated and coordinated control between CVT with electronic actuation and engine are proposed according to the development trend of CVT control strategy

which would have important guidance and reference to study the CVT and its control strategy.
