Title: Innovations by Kukhyun Ahn in Hybrid Vehicle Technology

Introduction

Kukhyun Ahn is an accomplished inventor based in Ann Arbor, MI, known for his contributions to hybrid vehicle technology. He holds 2 patents that focus on improving vehicle driveline operation and minimizing fuel consumption during engine starts and gear shifts.

Latest Patents

One of his latest patents is titled "System and method for improving vehicle driveline operation." This patent presents methods and systems for operating a hybrid driveline that includes both an engine and an electric machine. In this innovative approach, the engine and electric machine are operated according to a solution of a Hamiltonian that incorporates various parameters, including a first co-state, a second co-state, an engine fuel flow parameter, a rate of change of battery state of charge parameter, and an emissions flow rate parameter.

Another significant patent by Ahn is "Minimizing engine pull-ups and gear shifts in a hybrid vehicle." This invention describes a hybrid vehicle that consists of powertrain components such as an engine, an automatic transmission, and a traction motor. The traction motor is selectively coupled to the engine via a clutch and to the transmission. A controller is programmed to manage these components effectively. The vehicle operates over a drive cycle that includes multiple engine starts and transmission gear shifts. The amount of fuel consumed during these operations is stored on an on-board storage device. Subsequently, the engine and transmission can be inhibited from starting and shifting gears based on the recalled fuel consumption data.
