Abstract
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.
