Title: Keisuke Ajimoto: Innovator in Transmission Technology

Introduction

Keisuke Ajimoto is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of transmission technology, holding a total of 15 patents. His innovative designs have advanced the functionality and efficiency of continuously variable transmissions.

Latest Patents

Among his latest patents is a shift control device for continuously variable transmission. This device includes a converter that transforms continuous accelerator positions detected by an accelerator pedal sensor into a stepped position. The controller then adjusts the gear ratio of the transmission based on this converted step position. The converter also creates a hysteresis effect regarding the step position, which is activated when the accelerator depression amount increases or decreases. Additionally, when the step position reaches a predetermined level, the controller executes kick-down control to lower the gear ratio.

Another notable patent is an engine rotational speed display device. This device features an engagement state determination module that assesses the engagement state of a lock-up clutch. It also includes a target rotational speed setting module that establishes a target turbine rotational speed based on the selected gear stage. The display selection unit determines which rotational speed to show based on the engagement state of the lock-up clutch. Furthermore, a time measuring module tracks the elapsed time since a gear shift operation, while a limiting module controls the variation in the displayed rotational speed over time.
