Latest Patents
One of Joon-Bae Kim's latest patents is a hydraulic control system for automatic transmission. This invention discloses a hydraulic control system that manages a powertrain, which includes a first friction element used as an engine brake to discontinue the operation of a one-way clutch in the transmission. Additionally, a second friction element operates only when the first friction element is disengaged. The system comprises a manual valve that includes a forward range port for exhausting hydraulic pressure when driving in a forward range, and an L range port for low-speed control. A switch valve is controlled by engine brake signal pressure, solenoid pressure, and forward range pressure, selectively supplying control pressure to both friction elements.
Another significant patent by Kim is also a hydraulic control system for automatic transmission. This invention provides a hydraulic control system for controlling a powertrain that includes four clutches and two brakes. A first pressure, controlled by a first solenoid valve, is selectively supplied to two clutches under the control of a first switch valve. A second pressure, controlled by a second control valve, is supplied to another clutch and a first brake under the control of a second switch valve. Hydraulic pressure from a manual valve port is supplied to yet another clutch via a control valve, while hydraulic pressure from another port is supplied to a second brake via another control valve, with both control valves managed by a third solenoid valve.
