Title: The Innovative Contributions of Toshiaki Kasahara

Introduction

Toshiaki Kasahara is a notable inventor based in Kanagawa, Japan, with a remarkable portfolio of 9 patents to his name. His inventive work primarily focuses on advancements in vehicle steering systems, showcasing his significant contribution to the automotive industry.

Latest Patents

Among his latest innovations are two patents that revolutionize vehicle steering control. The first patent is a vehicle steering controller and method. This invention relates to a vehicle steering device that facilitates the control of steering in a steer-by-wire vehicle. It employs a steering instrument that receives input from the driver and a turning device that manipulates the wheel(s). The invention features a selectively engageable backup clutch, positioned between the steering instrument and the turning device, which engages based on steering state signals and turning state signals.

The second patent, a vehicle steering device and control method, introduces a system with a selectively engageable clutch located between the steering wheel and the turning mechanism. This clutch features two positions: an engaged position for mechanical connection and a disengaged position for steer-by-wire control. During this control mode, a reaction force actuator applies force to the steering wheel, while a turning actuator applies torque to the turning mechanism. Furthermore, to avoid erroneous clutch engagement caused by differences in angular acceleration, a controller monitors conditions that may lead to such errors and adjusts actuator functions accordingly.
