title = "A new CVT powertrain without jet start behaviour : analysis of design, dynamics and control",
abstract = "Due to rotating inertias within the engine and transmission, the response of a vehicle during large engine speed shifts may appear reluctant or even counteracting. Reminiscent of comparable behaviour seen in aircraft jet-propulsion, this phenomenon is also referred to as 'jet-start'. To overcome this behaviour, a CVT powertrain is augmented with a planetary gear set and compact steel ywheel. The new transmission seamlessly combines two contradictory features: the driveability in terms of the pedal-to-wheel response is greatly improved and a large leap towards optimal fuel economy can be made. This is achieved by cruising the vehicle at extremely low engine speeds, using the large ratio-coverage of the CVT. The ywheel acts as a 'peak shaver' during speed shifts: it delivers power during engine acceleration and absorbs kinetic energy during engine decelerations. In this paper, optimal design, system dynamics and control aspects of the new powertrain are discussed.",
