    摘要： The drive torque of a motor for driving a vehicle wheel, as shown in (a), during the period between the start of steering t1 and an instant t2 when a prescribed interval TM1s has passed, is controlled so as to be a value which is temporarily increased from the intended motor torque by just the amount indicated by the solid line waveform in (a); and during the period between t2 and an instant t4 when a prescribed interval TM2s has passed, the drive torque of a motor for driving a vehicle wheel is controlled so as to be a value which is temporarily decreased from the intended motor torque by just the amount indicated by the solid line waveform in (a). In the t1 - t2 interval (initial stage) of (c), the turning moment becomes large according to the difference between the turning moment of the turning direction of the outer wheel Mout and the turning moment (restoring moment) of the turning direction of the inner wheel Min. The increment in the yaw rate promptly rises in the initial stage of the instant t1 - t2 as indicated by a solid line in (b), in accordance with the increase in the apparent lateral force caused by the increase in the turning moment, thus the yaw rate is caused to rise without delay, and thereby it is possible to greatly improve the steering response (initial turning characteristics) of the vehicle.

    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 ΔFf, ΔFr from a variation in road wheel speeds Vw. An estimation section 53 estimates vehicle body vibrations along with the variation in Tw (pitching vibration θp and bouncing vibration xb) and other vehicle body vibrations (θp, xb) along with ΔFf, ΔFr. 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 (θp, 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.
