Abstract:
1. A sprung mass damping control system of a vehicle, which suppresses sprung mass vibration generated in a vehicle body by adjusting a driving control amount of a drive source, comprising: a spring vibration control amount calculating device that sets a sprung mass damping control amount for suppressing the sprung mass vibration; a drive source control device that executes sprung mass damping control by controlling the driving control amount of the drive source to realize the sprung mass damping control amount; and a sprung mass damping control amount adjusting apparatus that adjusts the phase of a sprung mass damping control signal related to the sprung mass damping control amount according to the situation, wherein the drive source control device executes sprung mass damping control by controlling a motor-generator control amount of a motor-generator that is driven by a waveform signal, or a motor control amount of a motor or a generator capable of operating as a motor that is driven by the waveform signal, and the sprung mass damping control amount adjusting apparatus adjusts the phase of the sprung mass damping control signal related to the sprung mass damping control amount according to the waveform signal, and the phase of the waveform signal is shifted when the responsiveness of at least one of the drive source or a driving control amount transmitting apparatus that transmits a driving control amount output from the drive source to a driving wheel decreases.
