Title: The Innovative Contributions of Hiroki Shimoyama

Introduction

Hiroki Shimoyama, an accomplished inventor based in Ebina, Japan, has made significant strides in the field of automotive technology. With a total of 11 patents to his name, he has established himself as a leading innovator in developing advanced shift control methods and systems for vehicles equipped with automatic transmissions.

Latest Patents

Shimoyama's latest works include two notable patents focused on shift control methods and systems. The first patent provides a detailed shift control method that involves setting a basic target synchronization rotation speed during a shift. This method determines whether an accelerating intention exists during a downshift with driving force requirements. If the intention to accelerate is present, the method sets a first target input shaft rotation speed, which is progressively corrected from the basic target synchronization speed. Conversely, if there is no intention to accelerate, a second target input shaft rotation speed is established by either maintaining or decreasingly correcting the basic target speed.

The second patent outlines a shift control method tailored for vehicles with automatic transmissions. This method consists of setting a basic target synchronization rotation speed and adjusting the target input shaft rotation speed when a downshift occurs without a driving force requirement. The corrected speed is derived by progressively decreasing the basic synchronization speed, with a correction amount that increases as the vehicle's deceleration intensifies.
