Title: Osamu Sugitani: Innovator in Electric Vehicle Technology

Introduction

Osamu Sugitani is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of electric vehicle technology, holding a total of 4 patents. His work focuses on enhancing the performance and control of four-wheel drive electric vehicles.

Latest Patents

One of his latest patents is a four-wheel drive electric vehicle control device. This device is designed for a four-wheel drive electric vehicle that utilizes a motor/generator as its drive source. It features an electronically controlled coupling that manages the drive power transmission to the front and rear wheels. The system includes a 4WD control unit that outputs a transmission torque command value to achieve the four-wheel drive state based on the vehicle's condition. Additionally, the 4WD control unit incorporates a regenerative control intervention-coordinating controller. This controller ensures that when regenerative control by the motor/generator is activated during the four-wheel drive state, the transmission torque of the electronically controlled coupling is set to zero before initiating regenerative control.

Another notable patent is a device for controlling the distribution force in a four-wheel drive vehicle. This device includes a driven wheel drive force distribution reference command value calculator. It determines a driven-wheel-oriented drive force distribution reference command value based on the estimated drive force sent to the drive wheels and a drive force reference distribution ratio. Furthermore, it features a driven wheel drive force distribution command value calculator that adjusts the driven-wheel-oriented drive force distribution reference command value by a correction amount that varies between the electric motor operating mode and the non-operating mode.
