Title: Masahide Iwazawa: Innovator in Electric Power Steering Technology

Introduction

Masahide Iwazawa is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of electric power steering technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and reliability of electric steering systems in vehicles.

Latest Patents

Iwazawa's latest patents include an "Electric power steering apparatus and electricity supply system" and a "Controller and control method for an electric power steering apparatus." The first patent describes a transformer section that transforms a primary voltage and outputs a secondary voltage. A control section inputs a first signal indicating the state of electricity supply from a primary power source through an in-vehicle network. The transformer section outputs a second signal indicating the state of electricity supply of the transformer section. When the input of the first signal is disrupted, the control section limits the driving electricity supplied to the steering motor based on at least one of the value of the secondary voltage and the electricity supply state of the transformer section indicated by the second signal. This innovation ensures that driving electricity is stably supplied to the steering motor, even if the input of the first signal is disrupted due to a failure in the in-vehicle network. The second patent outlines a controller that manages an electric motor to provide assist power corresponding to steering operations. It includes a detecting device, a filtering device, a judging device, and a determining device to ensure the reliability of the power source.
