Title: Innovations of Tatsuyuki Yoneda
Introduction
Tatsuyuki Yoneda is a notable inventor based in Toyota, Japan. He has made significant contributions to the field of automatic transmission technology. With a total of 2 patents, his work has had a considerable impact on automotive engineering.
Latest Patents
Yoneda's latest patents include a control system for automatic transmission. This innovative system features a frictional engagement element and an adjusted oil pressure producing mechanism. It is designed to optimize the oil pressure supplied from an oil pressure source. The system also includes a hydraulic servo that applies or releases the frictional engagement element based on the adjusted oil pressure. Additionally, it incorporates an engine load detecting mechanism and a vehicle speed detecting mechanism. An up-shift deciding mechanism determines whether an up-shift has been executed, while a pressure regulate signal generating mechanism calculates the regulated target pressure of the adjusted oil pressure. This ensures smooth operation during gear shifts.
Another significant patent by Yoneda is a method of detecting linear solenoid inter-terminal short of electronic control in automatic transmissions. This method detects a short between terminals of a linear solenoid by sensing when a PWM duty ratio falls below a reference duty ratio. The reference duty cycle is calculated based on expected normal and short duty ratios, ensuring reliable operation of the transmission system.
