ALEXANDRIA, Va., July 15 -- United States Patent no. 12,662,188, issued on June 23, was assigned to Hyundai Mobis Co. Ltd. (Seoul, South Korea).
"Steering angle estimation device and method for electric steering system" was invented by Tae Hong Kim (Yongin-si, South Korea).
According to the abstract* released by the U.S. Patent & Trademark Office: "A steering angle estimation device of an electric steering system. A first operator calculates a yaw rate. a second operator calculates an average value of rear wheel speeds. A Kalman filter predicts a yaw acceleration by filtering the yaw rate. A third operator estimates a steering angle also taking into account a slip angle by using the yaw rate and the yaw acceleration. A weight adjuster adj...
