Title: Innovations in Vehicle Steering Control by Taketosi Kawabe

Introduction

Taketosi Kawabe is a prominent inventor based in Tokyo, Japan, known for his contributions to vehicle steering control systems. With a total of three patents to his name, Kawabe has made significant advancements in the automotive industry, particularly in enhancing vehicle maneuverability and safety.

Latest Patents

Kawabe's latest patents include a model solving type vehicle steering control system. This innovative control system incorporates a steering wheel angle sensor, a vehicle speed sensor, and a turning behavior sensor, such as a side speed sensor and a yaw rate sensor. The system also features an actuator, like a hydraulic system, which alters the rear wheel steer angle based on a desired angle value. A microcomputer controller determines this desired angle by solving three distinct vehicle models. The controller first solves a reference model to establish a desired vehicle response, then an actual model to determine the necessary rear wheel steer angle, and finally, a second actual model to estimate the turning behavior based on the desired angle.

Another notable patent is a vehicle steering control system that utilizes a desired vehicle model. This system includes a steering wheel angle sensor, a vehicle speed sensor, a control unit, and an actuator for steering the front and/or rear wheel pairs. The control unit calculates desired values of yaw rate and lateral acceleration based on the sensed steering wheel angle and vehicle speed. It then determines the required steer angles to achieve these desired values and maintains the actual steer angle equal to a weighted average of the calculated values.
