Title: Innovations of Sang Chul Lee in Vehicle Powertrain Technology.
Introduction
Sang Chul Lee is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of vehicle powertrain technology, holding a total of 6 patents. His work focuses on enhancing the efficiency and control of vehicle powertrains, which is crucial for modern automotive engineering.
Latest Patents
One of his latest patents is a "Vehicle powertrain shift control method." This method involves determining which of four types of divided hydraulic pressure difference areas a main hydraulic pressure difference belongs to, using a controller. The main hydraulic pressure difference is calculated by subtracting a coupling-side preparatory hydraulic pressure from a coupling-side preliminary target pressure. The method also includes limiting the inclination of the control hydraulic pressure corrected calculated value during specific shift initiation phases to ensure it does not deviate from predetermined limit values.
Another notable patent is the "Shift control method for vehicle powertrain." This method includes determining whether a transmission is shifting and identifying the type of shifting. A predetermined control matrix is selected based on the shifting status, and necessary torque for the control target shift element is calculated. The control hydraulic pressure is then computed to implement the necessary torque, ensuring efficient operation of the vehicle's powertrain.
