    摘要： An object of the vehicle body vibration-damping control device according to the present invention is to achieve a targeted effect for damping the vehicle body vibration regardless of the responsiveness of an actuator for controlling the drive torque. The vehicle body vibration-damping control device has a body vibration estimating unit (205) for estimating a sprung mass behavior of a vehicle body based on input information during travel, and a torque command-value computing unit (206) for computing a correction torque value for correcting a drive torque command value applied to an engine (106) when the sprung mass behavior is controlled. The torque command-value computing unit (206) has regulator and tuning units (308, 309, 310) for calculating the correction torque value based on the result of estimating the sprung mass behavior, and a nonlinear gain amplifying unit (313) for amplifying the absolute value of the correction torque when in a region where the positive or negative attribute of the calculated correction torque value is reversed, and using the amplified value to correct the drive torque command value.

    摘要： 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.
