Patent number: 12017653Abstract: A traction control method and a traction control apparatus for a vehicle are provided. The traction control method includes: estimating driving torque for each wheel and a difference between left and right wheel rotation speeds; determining a situation, in which the difference between the left and right wheel rotation speeds exceeds a first set value, to be a split wheel spin situation; estimating a maximum coefficient of friction between a spinning wheel and a road surface in the split wheel spin situation and estimating a maximum driving torque, at which the road surface is acceptable, by the maximum coefficient of friction; and obtaining a difference between driving torque of the spinning wheel and the maximum driving torque to calculate a road surface limitation excess driving torque and determining entry into traction control when the road surface limitation excess driving torque exceeds a second set value.Type: GrantFiled: December 16, 2021Date of Patent: June 25, 2024Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATIONInventors: Yoon Seong Jeon, Chung Hee Han, Sung Keun Lim, Jae Min Yun

Patent number: 10605443Abstract: The present invention relates to a device for attaching and detaching a handle of a surgical light which is a medical lighting apparatus. The device, in the handle which is inserted into or separated from a surgical light shaft in a female-male coupling manner, comprises: a lock pin which protrudes in the axial direction of the surgical light shaft and is inserted into a lock hole formed on the handle so as to prevent the handle from being separated; a pin spring, supported on the surgical light shaft, for providing elastic force so that the lock pin protrudes to the outside of the surgical light shaft; a separation button which is provided on the outside of the handle and, when an external force for separating the handle from the surgical light shaft is applied, is pushed so as to enable the lock pin to be separated from the lock hole of the handle; and a button support body for supporting the separation button on the handle so that the separation button is movable to a certain degree.Type: GrantFiled: November 13, 2015Date of Patent: March 31, 2020Assignee: DENTIS CO., LTD.Inventors: Sung Guen Kim, Yoon Sang Oh, Jung Il Kim, Jae Min Yun, Myung Gyu Sim, Jeong Su Kim, Hyun Ki Hong, Duk Ho Kong
