Title: Shu Fujihashi and Vehicle Running Drive Control

Introduction

Shu Fujihashi is an inventor based in Tokyo, Japan, associated with Mitsubishi Jidosha Kogyo Kabushiki Kaisha. His patent work addresses control of a vehicle’s powertrain, including its engine and electric motors.

Latest Patents

Fujihashi is listed as an inventor on 1 patent: “Running Drive Control Device for Vehicle.” The invention concerns a vehicle whose front wheels are powered through a transaxle by an engine and a front motor, while a rear motor drives the rear wheels.

The system calculates the vehicle’s required running output and sets an output ratio between the front and rear wheels. It then controls the engine and motors according to those values. A transaxle oil-temperature sensor monitors the oil, and when its temperature reaches a specified threshold, a protection control unit reduces the proportion of output delivered to the front-wheel side. This adjustment helps protect the transaxle from excessive heat.

Career Highlights

Fujihashi’s documented patent contribution focuses on coordinating power delivery in a vehicle with multiple power sources. The disclosed control strategy balances the vehicle’s requested output with transaxle temperature protection.

Collaborations

The patent lists Jumpei Mori and Kazuhiro Ohi among Fujihashi’s coworkers. The available information identifies their association but does not specify their individual roles in the invention.

Conclusion

Shu Fujihashi’s patent describes a practical powertrain-control approach that adjusts front- and rear-wheel output to help protect a vehicle’s transaxle from high temperatures.
