    Abstract: Computing sections (31, 32) compute an average front-wheel speed VwF=(VwFL+VwFR)/2 and an average rear wheel speed VwR=(VwRL+VwRR)/2, and then the resulting values (VwF and VwR) are passed through band-pass filtering sections (33, 34) to extract only a component near a vehicle body resonance frequency, respectively, thus acquiring a vibration component (fVwF) of the front wheel speed (VwF) near the vehicle body resonance frequency and a vibration component (fVwR) of the rear wheel speed (VwR) near the vehicle body resonance frequency, the vibration components being representative of a vehicle body vibration. Computing sections (35, 36) are adapted to determine, from the resulting values (fVwF and fVwR), a back-and-forth displacement (Xtf) of the front wheels and a back-and-forth displacement (Xtr) of the rear wheels, the dis placements being representative of the vehicle body vibration; to determine, from the resulting values (Xtf and Xtr), the up-and-down dis placement of a portion above a front axle and the up-and-down displacement of a portion above a rear axle, the up-and-down displacements being caused by the vehicle body vibration, on the basis of the inherent relations between the back-and-forth displacement and the up-and-down displacement of the front wheels and the rear wheels, the relations being determined by the geometry of a suspension; to estimate the vehicle body vibration (an up-and-down bounce speed (dZv) and a pitch angular velocity (d8p)) from the front and rear up-and-down displacements of the vehicle body; and to determine an amount of driving and braking force compensation (L'i Td) which is necessary to alleviate the vehicle body vibration.
