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.

Traction control method and traction control apparatus for vehicle

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.

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.
