Abstract:
A method for damping vibrations of a four-wheel drive motor vehicle generated during a braking action, comprising the steps of:detecting a first rpm signal and a second rpm signal, the first rpm signal representing rotational speeds of wheels of a front axle of the four-wheel drive motor vehicle during a braking action, the second rpm signal representing rotational speeds of wheels of a rear axle of the four-wheel drive motor vehicle during the braking action; determining at least one difference value between the first rpm signal and the second rpm signal; and controlling the braking action to damp vibrations of the vehicle as a function of the at least one difference value, the damping step including: increasing the braking action on a first axle of the front and rear axles which has a higher rpm rate as a function of the at least one difference value.
