Latest Patents

Ko’s listed patents address ways to identify failures in vehicle braking systems.

“Method for Detecting Malfunction of Brake System Using Yaw Rate” describes a diagnostic process that compares measured vehicle deceleration or acceleration during braking with the required value. If the values indicate a problem, the method checks whether braking relied solely on regenerative braking. It can then use yaw-rate measurements to distinguish a left-side from a right-side friction-brake malfunction, and changes in measured deceleration or acceleration to help identify whether the issue is in the front- or rear-wheel friction brakes.

“Failure Diagnosis Method for Brake System of Vehicle” also compares the driver’s requested acceleration or deceleration with the vehicle’s current performance. When the values differ, the method evaluates braking torque, including the maximum torque available from regenerative braking, to help determine whether a failure involves the regenerative braking device or the front- or rear-wheel friction braking device.

Career Highlights

Ko’s listed work connects automotive engineering with diagnostic methods for braking systems. The described inventions focus on comparing requested and measured vehicle behavior to help locate faults across different braking components.
