Title: Chikashi Tagawa: Innovator in Control Systems and Vehicle Suspension Technology
Introduction
Chikashi Tagawa is a notable inventor based in Hiroshima-ken, Japan. He has made significant contributions to the fields of control systems and vehicle technology, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Tagawa's latest patents is an "Apparatus and method for diagnosing failures in control system." This invention provides a mechanism for diagnosing failures in multiple control units within a control system. The apparatus includes a detection device located outside the control units, which compares output data to identify any discrepancies. When a disparity is detected, the system determines that a failure has occurred in at least one of the control units.
Another significant patent is the "Suspension control apparatus for vehicle." This invention involves hydraulic cylinders positioned between the vehicle body and each wheel. A flow control valve manages the supply and drainage of hydraulic fluid to the operation chamber of these cylinders. The apparatus also features a lateral acceleration detection device that measures the vehicle's lateral acceleration. A high-pass filter processes this signal, and a rate of change calculation unit determines the rate of change of the lateral acceleration. The flow control valve is then regulated based on this rate of change, enhancing the vehicle's suspension performance.
