Title: Masahiko Akiyama: A Pioneer in Shift Range Control Technology

Introduction: Masahiko Akiyama, an accomplished inventor based in Tokyo, Japan, holds an impressive portfolio of 56 patents. His innovations primarily revolve around shift range control devices, significantly contributing to the automotive industry. His work demonstrates a profound understanding of motor control systems, essential for enhancing vehicle performance and efficiency.

Latest Patents: Among Akiyama's latest innovations are two notable patents: the "Shift Range Control Device" and the "Shift Range Control Apparatus." The Shift Range Control Device operates by switching a shift range through precise motor driving control. It incorporates a learning unit that determines position correction values based on reference angles when the output shaft signal is accessible post activation of a start switch. The first reference angle corresponds to the motor's position when a signal changes in reaction to motor rotation in one direction, while the second reference angle indicates the opposite motor movement. The device optimally sets a target motor angle by storing normal state time correction values.

The Shift Range Control Apparatus further refines this technology by managing a shift range switching system. It calculates motor angles from rotation angle signals, retrieves output shaft signals via sensors, and dynamically adjusts motor driving to achieve desired rotation angles. It is designed to ensure that the target rotation angle remains within set limits based on the positions of shift ranges prior to and following transition, demonstrating Akiyama's innovative approach to motor control and vehicle dynamics.
