Title: The Innovations of Tomoyuki Kashiwagi

Introduction

Tomoyuki Kashiwagi is a notable inventor based in Chita-gun, Japan. He has made significant contributions to the field of automotive technology, holding a total of 9 patents. His work focuses on enhancing vehicle systems, particularly in the areas of shift control and engine start safety.

Latest Patents

One of his latest innovations is the Shift-by-wire system. This system improves responsiveness to shift commands and ensures safety during operation. An electric motor generates a rotational output that is utilized to switch the ranges of an automatic transmission. A by-wire control circuit unit electrically manages the rotation of the electric motor to comply with an inputted shift command. If a re-shift command is issued during the switching control, the by-wire control circuit unit modifies the rotation control. This modification can be executed until the electric motor reaches a new target rotational position in accordance with the re-shift command.

Another significant patent is the Drive-permission apparatus. In this invention, an ECU controls a starter relay, while an output angle detector monitors the rotational angle of an output shaft in a rotary actuator. The ECU records a first rotational angle detected by the output angle detector when the starting switch is OFF. When the starting switch is ON, if the difference between a second rotational angle detected at that moment and the first rotational angle stored is not within a specified range, the ECU inhibits the operation of the starter relay to prevent engine start.
