Latest Patents

One of Hyunjun Son's latest patents is a hydraulic control system for the automatic transmission of vehicles. This system is designed to engage a reverse speed stage through the engagement of first and second friction elements. It includes a first solenoid valve that is normally open, controlling line pressure to generate a first hydraulic pressure. Additionally, a second solenoid valve, which is normally closed, manages line pressure to create a second hydraulic pressure. The system also features first and second switch valves, with the first switch valve selectively supplying the first hydraulic pressure to the second switch valve. A fail-safe valve is included to selectively supply either the first or second hydraulic pressure to the second friction element, allowing for efficient operation.

Another notable patent is a circuit for controlling hydraulic pressure in a torque converter. This circuit includes an engagement hydraulic pressure chamber that is independently installed within a fluid operation chamber. It features a torque converter control valve that stably decreases line pressure and supplies the decreased line pressure as operational hydraulic pressure. The design also incorporates a torque converter pressure control valve, which is managed by a linear solenoid valve to control D range pressure, and a lock-up switch valve that regulates hydraulic pressure supplied from the torque converter control valve.
