Patent ID: 8340865

Claim:
A vehicle wheel spin control apparatus comprising: a vehicle speed detecting unit that detects a vehicle speed; an accelerator pedal detecting unit that detects a displacement of an accelerator pedal; an engine torque control device; and a control unit that is arranged to determine whether a predetermined operation and a predetermined cancellation condition are satisfied based on the vehicle speed, a speed gradient value, and the displacement of the accelerator pedal and whether wheel spin occurs; wherein the control unit is arranged to perform an engine torque limit control with the engine torque control device when the predetermined operation condition is satisfied and wheel spin occurs; wherein the engine torque limit control includes: reducing an engine torque to a first torque value (TQ 1 ); reducing the engine torque to a second torque value (TQ 2 ) with a first torque gradient (S 1 ) according to a variation in the vehicle speed; and maintaining the engine torque to the second torque value (TQ 2 ) in a case that the vehicle speed is reduced after a predetermined time (t 1 ) has elapsed from an inception of reducing the engine torque to the first value (TQ 1 ).
