Title: Naoyuki Hagiya: Innovator in Vehicle Traction Control Systems
Introduction
Naoyuki Hagiya, an accomplished inventor based in Ageo, Japan, holds a noteworthy collection of seven patents. His innovative contributions primarily focus on traction control systems for motor vehicles, enhancing safety and performance on the road.
Latest Patents
Among his latest inventions is a cutting-edge traction control system designed for motor vehicles. This system meticulously monitors on-driving wheel speed during a specific time interval initiated when traction control is activated. If no instance of no-driving wheel speed occurs during this period, the throttle opening degree command is systematically reduced to a predetermined lower limit, shifting the control to a low friction coefficient mode. Another significant innovation is his traction control method and apparatus for vehicles, which involves regulating vehicle traction by reading throttle opening and closing speed values from a throttle control map. This method adjusts the throttle based on the differential speeds of driving and non-driving wheels, ensuring optimal vehicle performance.
