摘要： A vehicle body vibration estimating device for estimating a vehicle body vibration as a sprung mass of a vehicle where wheels are suspended via a suspension device. The vehicle body vibration estimating device includes a wheel speed physical quantity detecting section and a vibration estimating section. The wheel speed physical quantity detecting section detects a wheel speed physical quantity related to wheel speed, which is a circumferential velocity of a wheel. The vibration estimating section estimates the vehicle body vibration from a correlation relationship between displacements in a back-and-forth direction and displacements in an up-and-down direction of the wheels with respect to the vehicle body, and the wheel speed physical quantity detected by the wheel speed physical quantity detecting section.

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 vehicle body spring vibration. When a state of the correction torque amplitude being greater than a predetermined amplitude continues for a given predetermined time, a control apparatus outputs a hunting time correction torque command smaller than a normal time correction toque command. When a state of the correction torque amplitude being smaller than or equal to the predetermined amplitude continues for a first predetermined time, the control apparatus returns the output of correction torque command from the hunting time correction torque command to the normal time correction torque command. The control apparatus continues the output of the hunting time correction torque command if the state in which the correction torque amplitude exceeds the predetermined amplitude continues for the given predetermined time, before the expiration of the first time period.
