  • Vehicle body vibration-damping control device
    Patent number: 9187090
    Abstract: An object of the vehicle body vibration-damping control device according to the present invention is to achieve a targeted effect for damping the vehicle body vibration regardless of the responsiveness of an actuator for controlling the drive torque. The vehicle body vibration-damping control device has a body vibration estimating unit (205) for estimating a sprung mass behavior of a vehicle body based on input information during travel, and a torque command-value computing unit (206) for computing a correction torque value for correcting a drive torque command value applied to an engine (106) when the sprung mass behavior is controlled.
