He is credited with 2 patents and has worked with Hyundai Motor Company and Kia Corporation.

Latest Patents

Ahn’s patent, “Hybrid Electric Vehicle and Method of Driving Control for Same,” describes controlling fuel-injection timing when an engine start is required. The method can inhibit engine injection when specified control conditions are met, allow injection once the relevant conditions are satisfied, and coordinate reaction-force control through a motor directly connected to the engine. The approach is intended to improve fuel efficiency during engine starts.

His patent, “Hybrid Electric Vehicle and Method of Driving Control Therefor,” addresses switching from electric-vehicle mode to hybrid-vehicle mode when a kick-down shift is also required. The method determines available torque for the motors and uses that information, along with the type of shift, to select motor operating points before the shift is complete. This is designed to make the mode transition and kick-down shift faster.

Career Highlights

Ahn’s listed career includes work with Hyundai Motor Company and Kia Corporation. His patent work reflects a focus on hybrid powertrain control and coordinated operation of engines and electric motors.

Collaborations

His professional associations with Hyundai Motor Company and Kia Corporation connect his work to automotive organizations developing vehicle technologies. The patent descriptions emphasize control strategies for hybrid vehicles.

Conclusion

Tae Jun Ahn’s two patents address practical challenges in hybrid-vehicle operation, with methods aimed at improving engine-start efficiency and accelerating mode changes and kick-down shifts.
