1. A method for stabilizing a vehicle during a traction control event, the method comprising:
- receiving signals indicative of wheel speed and vehicle velocity at a controller of the vehicle;
determining a wheel slip of the vehicle based on a comparison of the wheel speed to the vehicle velocity;
determining, based on the wheel slip, whether a burnout condition exists;
incrementing a counter when a burnout condition exists; and
adjusting a damping force of at least one damper associated with a suspension of the vehicle when the burnout condition exists and the counter exceeds a threshold.

Abstract
Systems and methods for stabilizing a vehicle during a traction control event are disclosed. Signals indicative of wheel speed and velocity of the vehicle may be received at a controller of the vehicle and compared to determine wheel slip. Based on the wheel slip, the controller determines whether a burnout condition exists. A damping force of at least one damper associated with a suspension of the vehicle may be adjusted when a burnout condition is detected.

17. A vehicle, comprising:
-
at least one wheel; a wheel speed sensor and a vehicle velocity sensor; at least one damper operatively associated with a suspension system of the vehicle; and a controller, the controller being configured to; receive signals indicative of sensed wheel speed and vehicle velocity; based on the received signals, determine whether a burnout condition exists; run a counter until a count of the counter exceeds a calibratable threshold when a burnout condition exists; and adjust a damping force of the at least one damper when the burnout condition exists and the counts of the counter exceed the calibratable threshold. - View Dependent Claims (18, 19)
