Increasing the Vehicle’s Dynamic Performance by Developing a Continuously Variable Transmission

Modeling and Sensitivity Analysis of Full Toroidal Continuously Variable Transmission

High-performance simulations of continuously variable transmission dynamics

The paper describes a parallel computational model simulating continuously variable transmission (CVT) dynamics. A specific feature of the CVT model is the combination of relatively small problem sizes (about 1000 unknowns) and high computational costs (up to several weeks of sequential code computations for a thirty seconds simulation period). The main source of computational complexity here i...

Design of Continuously Variable Transmission (CVT) with Metal Pushing Belt and Variable Pulleys

Nowadays, automakers have invested in new technologies in order to improve the efficiency of their products. Giant automakers have taken an important step toward achieving this objective by designing continuously variable transmission systems (CVT) to continuously adapt the power of the engine with the external load according to the optimum efficiency curve of e...

Control of a Continuously Variable Transmission System

This paper proposed control strategies for the modern mechatronic Continuously Variable Transmission (CVT) System using three different techniques; The Ziegler-Nichols, Linear Quadratic and Pole-Placement methods. The results of the system responses of the designed control schemes were successfully simulated using MATLAB. Comparing the results showed that controller implemented using the Pole-P...

Adaptive Continuously Variable Compression Braking Control for Heavy-Duty Vehicles

Modern heavy-duty vehicles are equipped with compression braking mechanisms that augment their braking capability and reduce wear of the conventional friction brakes. In this paper we consider a heavy-duty vehicle equipped with a continuously variable compression braking mechanism. The variability of the compression braking torque is achieved through controlling a secondary opening of the exhau...
