Abstract:
A system, method and computer program product is provided for detecting if a vehicle has spun. A normal force and a lateral force of each of a front and rear axle of a vehicle is estimated. A coefficient of friction representative of a surface is estimated. Lateral momenta of the front and rear axles based on the coefficient of friction and the normal and lateral forces is calculated. Whether a surplus momentum is present, is determined. If the surplus momentum is present, a yaw rate of the vehicle is integrated respect to time to obtain a vehicle rotation estimation.
