VEHICLE ATTITUDE CONTROL DEVICE

A vehicle attitude control device includes a controller including a low-pass filter. The controller calculates a manipulated variable of the actuator that allows the roll of the vehicle to be suppressed. The controller processes the roll angle acceleration with the low-pass filter, integrates the roll angle acceleration in which a high-frequency component has been removed by the low-pass filter, and converts a roll angle velocity obtained by the integration, into the manipulated variable. The low-pass filter has a first vehicle speed-cutoff frequency characteristic in which a cutoff frequency becomes higher with increase in the vehicle speed, and the first vehicle speed-cutoff frequency characteristic is designed such that a peak frequency in roll vibration coincides with a local minimum roll frequency in wheelbase filtering, the roll vibration being amplified by a dead time and a phase delay in control by the controller.
