Latest Patents

Okazaki's latest patents focus on advanced control systems for automatic transmissions. One of his patents describes a control system designed to execute an upshift from an off-going speed ratio to an on-coming speed ratio. This system operates by managing the release of hydraulic pressure from the frictionally engaging element used for the off-going speed ratio while simultaneously controlling the supply of hydraulic pressure to the on-coming speed ratio. The system includes first and second off-going pressure releasing valves, which are responsible for releasing the hydraulic pressure, and a linear solenoid valve that regulates the operation of these valves based on the engine's throttle opening. The design ensures that the timing for releasing hydraulic pressure is optimized according to the throttle position.

Another patent by Okazaki details an automatic transmission that incorporates a torque converter equipped with a lock-up clutch. This invention features FIRST to FOURTH speed clutches that facilitate a shift from the off-going speed ratio to the on-coming speed ratio. The control system in this patent includes various valves that manage the hydraulic pressure during shifts, ensuring smooth transitions and improved vehicle performance.
