Yasuhiro Shimomura

Title: Innovator Profile: Yasuhiro Shimomura

Introduction

Yasuhiro Shimomura is a distinguished inventor based in Aichi, Japan. He holds a total of four patents, showcasing his innovative contributions to the field of motor control technology, particularly for vehicle applications. His work reflects a commitment to enhancing the functionality and safety of automotive systems.

Latest Patents

Among his notable innovations is a patent for a motor controller and method for controlling a motor, specifically designed to fully operate the window glass of a vehicle door. This motor controller employs a relay circuit linked to the motor, which adjusts switching contact states based on the movement of the window glass. It features an integrated FET and a sensor that monitors the motor's rotation speed, generating a detection signal that informs a CPU. The CPU processes this signal to create a duty signal, enabling efficient motor operation aligned with the detection waveform.

Additionally, Shimomura has patented a power window device aimed at reducing heating issues in the motors responsible for operating the window glass. Each vehicle door is equipped with an ECU that regulates the motor based on switch operations to elevate or lower the window. A pulse sensor detects the motor's rotation speed, sending signals to the ECU to determine if the window has reached its fully open or closed positions. If it detects a lock or completion of movement, the ECU deactivates the motor until specific activation conditions are met.
