Title: Innovations of Nobuaki Inagaki

Introduction

Nobuaki Inagaki is a prominent inventor based in Nishio, Japan. He has made significant contributions to the field of vehicle transmission technology, holding a total of eight patents. His work focuses on enhancing the efficiency and performance of vehicle transmission systems.

Latest Patents

One of his latest patents is a vehicle transmission device that includes an input member coupled to a combustion engine and a rotary electric machine. This device features an output member connected to the wheels and a speed change mechanism with multiple friction engagement elements that provide various shift speeds. The control device plays a crucial role in managing the speed change mechanism. During a regeneration downshift, while the rotary electric machine outputs regenerative torque, the control device sets a target increase capacity for the engagement-side element. It increases the transfer torque capacity of this element over a predetermined period while simultaneously decreasing the transfer torque capacity of the disengagement-side element.

Another notable patent is a control device designed for managing a transmission. This device executes special speed change control when the speed change mechanism shifts to a lower speed ratio in a negative torque prediction state. The disengagement hydraulic pressure is lowered to allow a disengagement element to slip, maintaining this slipping state throughout the entire speed change process.
