摘要： A method for estimating damping characteristics of shock absorbers in an active or semi-active suspension involves providing a reference model of a nominal relation between a road severity index related to vertical acceleration values, and the mean driving current of the control valves of the shock absorbers, acquiring respective relative acceleration or speed data of at least the front wheels of the vehicle with respect to the vehicle body, determining a value of the road severity index starting from relative acceleration or speed data of the front wheels of the vehicle with respect to the vehicle body, acquiring values representative of the mean driving current of the control valve of each shock absorber, comparing acquired value of the mean driving current with an expected value of the nominal mean driving current determined as a function of the road severity index according to the reference model, and determining a degradation condition if the acquired value does not correspond to the expected value.

摘要： In a method for operating a vehicle with wheel suspensions which each have a characteristic curve, the characteristic curve generates a relation between the weight of the vehicle, applied to each wheel suspension, and the respective height of the vehicle at the wheel suspension point. At least two height sensors detect the height at the wheel suspensions, a reference height is associated with the height sensors and represents a pre-defined loading state of the vehicle. The method provides: detecting the height, determining the forces applied to the vehicle, determining the acceleration of the vehicle on the basis of the forces applied to the vehicle, determining an estimated value for the mass of the vehicle from the forces and the acceleration of the vehicle, and determining values representing the reference heights from at least the estimated value for the mass of the vehicle, the characteristic curves of the wheel suspensions, and the detected heights.
