Latest Patents

One of his latest patents is for an alloy steel that exhibits excellent hydrogen embrittlement resistance and strength. This alloy steel includes boron (B) to improve hardenability and cobalt (Co) to enhance strength. The method of preparing this alloy steel involves appropriately mixing the components to form 100 vol % of tempered martensite as a constituent structure. This innovative approach results in a material that demonstrates superior resistance to hydrogen embrittlement while maintaining high strength.

Another significant patent involves a method of detecting deviation in the travel path of a vehicle. This method includes several steps: first, determining whether the steering torque of a driver and the motor torque of a motor-driven power steering apparatus have different directions. Next, it assesses whether the vehicle is traveling at a predetermined speed or higher, checks if the motor torque exceeds a certain magnitude, and finally, evaluates whether the change rate of the yaw rate is within a predetermined value. This invention aims to enhance vehicle safety by accurately detecting deviations in travel paths.
