Title: Yasuhiro Maeda: Innovator in Powertrain Control Technologies
Introduction
Yasuhiro Maeda is a prominent inventor based in Toyota, Japan. He has made significant contributions to the field of automotive technology, particularly in powertrain control systems. With a total of 2 patents to his name, Maeda's work focuses on enhancing the efficiency and reliability of hybrid motor vehicles.
Latest Patents
Maeda's latest patents include a "Powertrain control apparatus and method" and a "program for implementing the control method." This innovative control apparatus is designed for powertrains that incorporate automatic transmissions. It determines the occurrence of slip in a one-way clutch when a first rotation member and a second rotation member rotate relatively. If slip is detected, the system assesses whether the rotational speed difference between the two members has increased. If so, it executes a control to engage a predetermined frictional engagement element.
Another notable patent is the "Engine starting device and engine starting method for hybrid motor vehicles." This invention features a differential mechanism with multiple rotating elements connected to both an engine and electric motors. The system includes a transmission that establishes various transmission ranges by selectively operating coupling devices. An irreversible rotation member is integrated into the transmission to prevent reverse rotation through a one-way clutch. In the event of a malfunction in the second electric motor, the engine start control unit initiates the engine by driving the first electric motor while engaging the coupling devices.
