Title: The Innovations of Yoshifumi Shitara
Introduction
Yoshifumi Shitara is a notable inventor based in Hiratsuka, Japan. He has made significant contributions to the field of work vehicles, holding 2 patents that showcase his innovative approach to engineering and technology.
Latest Patents
Shitara's latest patents include a work vehicle and a control method for work vehicles. The first patent describes a work vehicle that features an accelerator operation amount generator. This generator receives the actual accelerator operation amount from the operator and generates a control accelerator operation amount. The engine controller then regulates the engine based on this control amount. Additionally, a storage component holds a table that sets the increasing speed for the control accelerator operation amount. The system determines the increasing speed based on the difference between the converted accelerator operation amount and the control accelerator operation amount from the previous control cycle.
The second patent outlines a work vehicle that incorporates a variable displacement hydraulic pump driven by an engine. This vehicle includes a hydraulic motor that forms a closed circuit with the pump, allowing it to travel using wheels driven by hydraulic fluid. A selector detects the operating state of a switch that changes the vehicle's traveling direction. The controller adjusts the relationship between the vehicle speed and the upper limit of the engine's rotational speed, ensuring that the upper limit increases as the vehicle speed approaches zero.
