Vibration-damping control device for vehicle

A vibration damping control apparatus for a vehicle, the vibration damping control apparatus comprising:

• a driving/braking torque producing section configured to produce a driving/braking torque of a wheel of the vehicle;
• a correction torque calculating section configured to calculate a correction torque to suppress a vehicle body sprung vibration;
• and
• a correction torque command outputting section configured to output a correction torque command to the driving/braking torque producing section, in accordance with the correction torque;
• the correction torque command outputting section being configured to output a hunting time correction torque command smaller than a normal time correction torque command when a state in which an 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 a predetermined amplitude continues for a first predetermined time length,
• moreover, the correction torque command outputting section being configured to output a returning time correction torque command restricted with restriction on the correction torque before the output of the correction torque command is returned to the normal time correction torque command,
• the returning time correction torque command being produced, by measuring, by counting, a time duration during which the state in which the amplitude of the correction torque is greater than or equal to the predetermined amplitude continues, and by increasing the restriction on the correction torque as the time duration measured by counting is longer.
