Title: **Inventor Katsuo Ohbai: Innovations in Anti-Skid Control Systems**

Introduction

Katsuo Ohbai, an inventive mind based in Anjo, Japan, has made notable contributions to the field of automotive safety. With two patents to his name, Ohbai has dedicated his career to advancing technologies that enhance vehicle control and passenger safety.

Latest Patents

The latest patent of Katsuo Ohbai pertains to an anti-skid control system, designed to optimize braking performance on varying road surfaces. This innovative system includes a hydraulic pressure generator that produces hydraulic brake pressure, alongside hydraulic pressure control valves that regulate the brake hydraulic pressure in the wheel cylinders. The integration of wheel speed sensors allows the system to detect the rotational speed of the wheels, while a sophisticated controller manages the hydraulic pressure control valves to either decompress or pulse-boost the brake hydraulic pressure based on signals from these sensors.

A significant aspect of this system is its ability to detect changes in road surface conditions. The controller features a road surface change judging device that identifies when a vehicle transitions from low to high friction surfaces. Once this shift is detected, the system adjusts the pulse boost control's duty ratio to enhance the braking response, ensuring optimal safety and control. Furthermore, a brake pedal depression amount detecting device continuously monitors the amount of brake pedal engagement, allowing for real-time adjustments to the system's performance.
