SPRUNG MASS DAMPING CONTROL SYSTEM OF VEHICLE, AND VEHICLE PROVIDED WITH SAID SYSTEM
First Claim
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.

Abstract
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 (the second motor-generator), includes 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 (a motor-generator 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 (a sprung mass damping control amount responsiveness compensating portion) that adjusts the phase of a sprung mass damping control signal related to the sprung mass damping control amount according to the situation. A vehicle is provided with this sprung mass damping control system.

7. A method of performing a sprung mass damping control in a vehicle, the sprung mass damping control suppressing at least a fluctuation in wheel speed due to bumps and dips in a road surface by outputting a driving control amount of a drive source over which a waveform signal based on that fluctuation has been superimposed, comprising a step of advancing the phase of the waveform signal 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 is low compared with when that responsiveness is high.
