Title: Kiminaga Shirakawa: Innovator in Automatic Transmission Technology
Introduction
Kiminaga Shirakawa is a notable inventor based in Kitatsuru, Japan. He has made significant contributions to the field of automatic transmission technology, holding a total of 7 patents. His work focuses on enhancing vehicle safety and performance through innovative failure detection systems.
Latest Patents
Shirakawa's latest patents include a failure detecting system and method for automatic transmission. This invention involves a failure detecting method and apparatus for an automatic transmission of a vehicle. It utilizes a vehicle speed sensor to monitor speed and an inhibitor switch to detect gear shift range positions. The method assesses whether the vehicle speed exceeds a predetermined value, checks for neutral range detection, and monitors for the absence of another gear shift range position after a set time. This allows for precise failure detection of the range signal line, ensuring optimal control of the automatic transmission under various driving conditions.
Another significant patent is a sensor failure and erroneous signal detection system designed for automobiles equipped with cruise control. This system prevents cruise control from engaging under specific conditions, such as when the vehicle is traveling below a certain speed or when the brake switch is activated. It also sets an error flag if the cruise control signal is erroneously generated. If any of the predetermined conditions are met, the system detects an error and instructs the automatic transmission to revert to normal operation.
