Measurement and Control of Slip in a Continuously Variable Transmission

IFAC Proceedings Volumes, 2004
Abstract Continuously Variable Transmissions are used to optimize engine efficiency in automotive drivelines. The efficiency profit however, is lost due to inefficiencies in the CVT itself. These losses occur mainly in the (hydraulic) actuation system and in the variator.

A passive, origami-inspired, continuously variable transmission

2014 IEEE International Conference on Robotics and Automation (ICRA), 2014
Transmissions play a vital role in machines by transforming the torque and speed of a motor into a desired output. They are often necessary for operating a motor at peak efficiency or power. The majority of variable transmissions are mechanically complex, large, and expensive, which limits scalability and is often cost prohibitive.

Nonlinear stabilization of slip in a continuously variable transmission

Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005
One way to predict and control the output torque of a geared neutral CVT is to use the relationship between slip in the variator and transmitted belt torque. This relationship is often referred to as the traction curve. For small slip values, the output torque increases almost linearly with slip.

On the efficiency of a prototype continuous variable transmission system

21st Mediterranean Conference on Control and Automation, 2013
In this paper we explore the performance capabilities of a new variable transmission system installed on a low fuel consumption, zero emission, prototype urban vehicle. Our focus is on measuring the efficiency of the continuous variable transmission system, namely, the Electronic Shift Variable Transmission (ESVT), which is presented here in a ...

Belt-pulley friction estimation for the Continuously Variable Transmission

IEEE Conference on Decision and Control and European Control Conference, 2011
This study describes an approach to estimate the maximum friction between the pushbelt and pulley set in a mass-produced Continuously Variable Transmission. Up-todate friction knowledge is useful to accurately determine the maximum transmittable torque and to monitor the variator condition.

Causes of Microslip in a Continuously Variable Transmission

Journal of Mechanical Design, 2007
The continuously variable transmission (CVT) is a type of transmission that can adopt any arbitrary gear ratio. Whereas typical transmissions utilize toothed gears, the CVT employs a sphere in rolling contact with a set of rollers; loads applied to the CVT are supported across these rolling contacts, resulting in microslips of varying amounts at each ...
