Latest Patents
Koumura's latest patents include a shift control apparatus for an automatic transmission and a lock-up control apparatus in automatic transmission. The shift control apparatus is designed to eliminate or reduce discomfort for drivers and passengers during slip conditions while maintaining necessary driving force. It utilizes a slip signal detected from wheel speed to manage gear stages effectively. If slip continues beyond a predetermined time, the system shifts to a predetermined gear stage to prevent further slip. Conversely, if the slip stops within the set time, the current gear stage is maintained.
The lock-up control apparatus features a torque converter with a lock-up clutch that connects the engine output shaft directly to the transmission input shaft. It includes a speed difference detector to monitor the rotational speeds of the engine and input shaft. This innovation allows for smooth engagement of the lock-up clutch without causing shift shock, thereby enhancing vehicle performance and reliability.
