Title: Kiyotaka Sawano: Innovator in Continuously Variable Transmission Technology
Introduction
Kiyotaka Sawano is a prominent inventor based in Fuji, Japan. He has made significant contributions to the field of continuously variable transmission (CVT) technology, holding a total of five patents. His innovative work focuses on enhancing the efficiency and performance of CVT systems.
Latest Patents
One of Sawano's latest patents is a controller and control method for a belt-type continuously variable transmission. This control device includes primary and secondary pulleys and a belt, which controls the gear ratio based on the running radius of the belt on a pulley by managing primary and secondary oil pressures. The transmission features a belt slip control unit and a belt slip control permission determining unit. The belt slip control unit oscillates the secondary oil pressure, estimates the belt slip condition by monitoring the phase difference between oscillation components, and reduces the actual secondary oil pressure to maintain a predetermined belt slip condition. Another patent focuses on controlling a belt-type continuously variable transmission, which decreases belt friction when the estimated accuracy of a belt slip condition is high and prevents excessive slipping when the accuracy is low.
