Title: Haruki Higashi: Innovator in Automotive Technology
Introduction
Haruki Higashi is a prominent inventor based in Hiroshima, Japan. He has made significant contributions to the automotive industry, holding a total of 7 patents. His innovative designs and technologies have advanced vehicle performance and efficiency.
Latest Patents
One of his latest patents is for a four-wheel drive vehicle. This vehicle is equipped with a transfer case that includes a center-differential, which delivers driving power to both front and rear axle assemblies when needed. It is shiftable between a two-wheel and a four-wheel drive mode of operation, as well as between a differential-locked and a differential-unlocked drive mode. Additionally, a free-wheeling drive mechanism with a clutch member is incorporated in an output shaft of an axle differential, allowing for disconnection when the vehicle is in the two-wheel drive mode. A controller is designed to cause a forced drive mode shift of the center-differential based on the detection of disconnection of the free-wheeling drive mechanism.
Another notable patent involves an improved apparatus for determining whether gear-shifting in an automatic transmission is completed. This system detects completion based on the rate of change in rotational speed of the output shaft of the torque converter and the expected rotational speed upon completion of gear-shifting. The system determines that gear-shifting is completed when the output shaft's rotational speed falls within a predetermined range and the rate of change is reduced below a specific value.
