  • Patent number: 8340865
    Abstract: The present invention provides a vehicle wheel spin control apparatus that, when it is determined that a wheel spin occurs, reduces engine torque to prevent the wheel spin, including: detecting driving control information and information on the state of a vehicle and determining whether basic conditions required to perform engine torque limit control to prevent the wheel spin are satisfied; when the basic conditions are satisfied, calculating a speed variation and the speed gradient value, and comparing the speed gradient value with a predetermined speed gradient value to determine whether a spin occurs; when it is determined that the spin occurs, using a torque gradient map set according to the current engine torque to perform the engine torque limit control; and when the vehicle speed is reduced by the engine torque limit control and cancellation conditions are satisfied, canceling the engine torque limit control and returning to normal control.
