Title: VEHICLE DAMPING CONTROL DEVICE
Abstract:
When outputting a correcting-torque command value to a drive/braking torque generation means on the basis of a correcting torque that suppresses sprung-weight vibrations, if the amplitude of the correcting torque has remained at or above a prescribed amplitude for a given duration, the disclosed vehicle damping control device outputs a hunting correcting-torque command value that is smaller than a normal correcting-torque command value. If the amplitude of the correcting torque subsequently remains at or below the prescribed amplitude for a first amount of time, the outputted correcting-torque command value is reverted from the hunting correcting-torque command value to the normal correcting-torque command value, but if the amplitude of the correcting torque exceeds the prescribed amplitude and remains in that state for a given duration before the first amount of time passes, the vehicle damping control device continues outputting the hunting correcting-torque command value. This configuration suppresses hunting upon a return to normal damping control, thereby increasing the execution frequency of damping control.
