Title: Katsuhiro Hatta: Innovator in Automatic Transmission Technology
Introduction
Katsuhiro Hatta is a prominent inventor based in Uji, Japan. He has made significant contributions to the field of automatic transmission technology, holding a total of 10 patents. His work focuses on improving the efficiency and performance of automatic transmissions in vehicles.
Latest Patents
Among his latest patents is a shift control method for an automatic transmission. This innovative speed change control apparatus includes a transmission control unit that manages gear-changing. The control unit is designed to discriminate a fluid temperature and rotational speed zone based on the hydraulic fluid temperature and engine speed at the start of gear-changing. It detects the time period from the end of dead-stroke elimination of an engagement-side hydraulic clutch to the start of actual gear-changing. If certain conditions for executing learning correction are met, and if the time period exceeds an upper limit, the control unit increases the learning-correction time. Conversely, if the time period is shorter than a lower limit, the learning-correction time is decreased. This learning correction helps prevent degraded shift response and shift shocks, which can arise from individual differences in the automatic transmission and variations in engine speed or fluid temperature.
