Title: Kenji Hattori: Innovating Vehicle Control Technologies

Introduction

Kenji Hattori is a prominent inventor based in Kanagawa, Japan, known for his significant contributions to vehicle control technologies. With a total of three patents to his name, Hattori has been instrumental in advancing automotive engineering, particularly in areas that enhance vehicle performance and driver experience.

Latest Patents

Hattori’s latest innovations include two noteworthy patents related to vehicle control systems:

1. **Vehicle Controlling Device**: This patent features a frictional engagement element positioned between a drive motor and a driving wheel. The device comprises a shifting unit that allows the selection between a travel range and a non-travel range. During the selection of the travel range, a first parameter, which includes a first motor torque value, is obtained. Simultaneously, during the non-travel range selection, a second parameter is obtained, which includes a second motor torque value. The operating unit calculates a zero point hydraulic pressure command value, thereby detecting the zero point of a clutch between the drive motor and the driving wheel.

2. **Oil Pressure Controller for Automatic Transmission**: This innovative controller generates a pre-charge shelf pressure that is supplied to a starter clutch by quickly lowering a command hydraulic pressure. After a rapid increase in command hydraulic pressure, it produces a capacity adjustment pressure to the starter clutch by gradually increasing hydraulic pressure. This adjustment allows for reduced selection shock when transitioning from the N-range to D-range during braking operations, improving vehicle startability and overall performance.

Career Highlights

Kenji Hattori has made significant contributions while working for major automotive companies, including Nissan Motor Company Limited and Jatco Corporation. His work at these organizations has solidified his reputation as an innovative thinker in the automotive field.
