  • Patent number: 12017653
    Abstract: 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.

  • Patent number: 11541860
    Abstract: A system and method for detecting brake judder in a vehicle may include storing information related to determining whether judder was generated when a vehicle was braked, and facilitating easy recognition of a vehicle in which judder was generated, on the basis of stored information without performing methods such as a separate driving reproduction test and a disc thickness measurement test when maintaining later.

  • Patent number: 10605443
    Abstract: 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.

  • Patent number: 10576955
    Abstract: An emergency braking control system of a vehicle using a limited slip differential, may include a brake circuit formed by splitting hydraulic lines for left and right side drive wheels; a limited slip differential disposed to restrict the differential of the drive wheels; and a controller for determining whether or not the braking circuit failure occurs in a braking situation, and performing the engagement control of the limited slip differential, wherein the controller is configured to perform the engagement control of the limited slip differential to distribute a braking force to drive wheel connected to a hydraulic line where the braking circuit failure occurs when the brake circuit failure occurs in the braking situation.

  • Publication number: 20160125295
    Abstract: The present invention relates to a user-interaction toy and an interaction method of the toy, and more particularly, to a user-interaction toy and an interaction method of the toy that recognize an intention of a user's action and select a reaction thereto, and output the intention and the reaction to a user. According to embodiments of the present invention, there is a provided a user-interaction toy that can more accurately determine a user's intention by sensing means including two or more sensors, and as a result, an appropriate response is made to a user to commune with the user through voice, sound, an action, and video, thereby enjoying the toy more vividly, a toy which interacts with the user.
