Latest Patents

Cheol Ha Lee's latest patents include an "Apparatus and method for determining careless driving." This invention provides a reliable way to identify careless driving by generating normal driving patterns using driving performance data collected at the beginning of a trip. The system detects careless driving patterns that exceed a predetermined threshold and establishes a boundary between normal and careless driving using a supervised learning method. The driver's careless driving is then assessed based on this determined boundary.

Another significant patent is the "Driving concentration level calculating apparatus and method, and system and method for warning of vehicle collision using the same." This invention features a controller that acquires the acceleration of a traveling vehicle and measures its relative velocity to a preceding vehicle. It effectively removes noise from the collected data and calculates multiple correlation values based on the cleaned acceleration and relative velocity. The controller then identifies the time at which the maximum correlation value occurs, which is interpreted as the driving concentration level.
