Title: Hiromi Maehata: Innovator in Vehicle Control Systems

Introduction

Hiromi Maehata is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of vehicle control systems, holding a total of 5 patents. His work focuses on enhancing vehicle safety and performance through innovative technologies.

Latest Patents

One of Maehata's latest patents is a vehicle wheel slip control system. This system utilizes sensors to detect the rotational speeds of each vehicle wheel. A slip detection reference value is calculated based on these detected speeds. Acceptable slip ranges for the wheels are determined according to this reference value. The system compares the rotational speeds of the wheels with their corresponding acceptable slip ranges. When the speeds fall outside these ranges, slip controls are activated. Additionally, the system selects the highest rotational speed among the wheels and calculates the differences between this speed and the others. The slip detection reference value is then adjusted based on these differences.

Another significant patent involves the detection of abnormalities in rotational speed sensors. This technology is particularly useful for anti-skid control systems. It estimates the time period for the next pulse generated by the sensor based on the latest pulse interval and the wheel's inertial force during braking. If the subsequent pulse is not produced within the estimated time, the system determines that an abnormality exists. This quick detection allows for fail-safe control in braking systems, enhancing vehicle safety.
