Vehicle damping control device

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

• at least one of a driving torque producing device configured to produce a driving torque of a wheel and a braking torque producing device for producing a braking torque of the wheel;
• and
• a controller configured to:
• calculate a correction torque to suppress a vehicle body spring vibration of the vehicle,
• output a non-hunting correction torque command in accordance with the correction torque to the one of the driving torque producing device and the braking torque producing device,
• output a hunting time correction torque command smaller than a non-hunting time correction torque command to the one of the driving torque producing device and the braking torque producing device when a state in which an amplitude of the correction torque is greater than a predetermined amplitude continues for a given predetermined time length,
• return to output the non-hunting time correction torque command from the hunting time correction torque command to the one of the driving torque producing device and the braking torque producing device when 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,
• continue to output the hunting time correction torque command to the one of the driving torque producing device and the braking torque producing device when the state in which the amplitude of the correction torque is greater than the predetermined amplitude continues for the given predetermined time length before elapse of the first predetermined time length, and
• output the hunting time correction torque command to the one of the driving torque producing device and the braking torque producing device and prevent the returning to output the non-hunting time correction torque, even when the state in which the amplitude of the correction torque is smaller than or equal to the predetermined amplitude continues, when a condition in which the state in which the amplitude of the correction torque is greater than the predetermined amplitude continues for the given predetermined time length is continued a number of times which is greater than a predetermined number after the elapse of the first predetermined time length and before elapse of a second predetermined time length.
