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.

摘要： A calculation section 51 calculates a requested braking-or-driving torque Tw from accelerator opening angle APO and brake pedal depression force BPF and a calculation section 52 calculates forward-or-backward direction external disturbances ”Ff, ”Fr from a variation in road wheel speeds Vw. An estimation section 53 estimates vehicle body vibrations along with the variation in Tw (pitching vibration ¸p and bouncing vibration xb) and other vehicle body vibrations (¸p, xb) along with ”Ff, ”Fr. A calculation section 54 calculates a damping purpose braking-or-driving torque correction quantity to suppress these vehicle body vibrations. A calculation section 56 calculates a damping purpose braking-or-driving torque correction quantity command dTw* to suppress vehicle body vibrations (¸p, xb) from the torque correction quantity and suppression priority levels set to take the higher priority of the suppression of the pitching vibration with a priority level setting section 55, while the priority levels are satisfied, and the braking-or-driving force of the vehicle is corrected by dTw*.

摘要： A vehicular vibration damping control apparatus calculates a correction torque to suppress vehicle body sprung vibration. In outputting a correction torque command to a driving/braking torque producing device, the control apparatus outputs a hunting time correction torque command smaller than a normal time correction toque command when a state in which amplitude of the correction torque is greater than or equal to a predetermined amplitude continues for a predetermined time length, and thereafter to return an output of the correction torque command from the hunting time correction torque command to the normal time correction torque command if a state in which the amplitude of the correction torque is smaller than or equal to the predetermined amplitude continues for a first predetermined time length. The frequency of performing the vibration damping control is increased by suppressing occurrence of hunting at the time of return to the normal vibration damping control.

摘要： A correction torque command is outputted to a driving/braking torque producing means, in accordance with a correction torque to suppress a vehicle body sprung vibration. When the amplitude of the correction torque is continuing to be greater than or equal to a predetermined amplitude continues for a predetermined time length, a control apparatus outputs a hunting time correction torque command smaller than a normal time correction toque command. Thereafter, when a state of the amplitude of the correction torque being smaller than or equal to the predetermined amplitude continues for a first predetermined time length, the control apparatus returns the output of the correction torque command from the hunting time correction torque command to the normal time correction torque command. Furthermore, the control apparatus continues the output of the hunting time correction torque command if the state in which the amplitude of the correction torque exceeds the predetermined amplitude continues for the predetermined time length, before the expiration of the first time period. The apparatus can restrain the hunting at the time of return to the normal damping control and thereby improve the frequency of carrying out the damping control.
