Title: The Innovations of Tomoyuki Shibata

Introduction

Tomoyuki Shibata is a notable inventor based in Chiryu, Japan. He has made significant contributions to the field of hybrid vehicle technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of hybrid vehicles, which are becoming increasingly important in today's automotive industry.

Latest Patents

Shibata's latest patents include innovative designs for hybrid vehicles. One of his patents describes a hybrid vehicle that is configured to control both an engine and a motor. This vehicle operates in various drive modes, including a Charge Depleting (CD) mode, where electric power is consumed, and a Charge Sustaining (CS) mode, which maintains the state of charge of the power storage device. In this design, when a driver selects a sequential position while in an accelerator-off state, the vehicle narrows the range of braking torque applicable in the CD mode compared to the CS mode.

Another patent outlines a vehicle that incorporates an engine, a motor generator (MG), and a planetary gear device. This design includes a battery, a converter to boost voltage, and an inverter for power conversion. The MG generates counter-electromotive voltage when rotated by the engine, creating braking torque when the counter-electromotive voltage exceeds the output voltage of the converter. During inverter-less running control, the controller adjusts the voltage difference when the battery's chargeable power falls below a predetermined value.
