Title:
VEHICLE POSTURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2020131738
Kind Code:
A
Abstract:
To provide a vehicle posture control device that enables operability of steering by a driver to be improved without complicating configuration of a suspension.SOLUTION: A posture control device 4 comprises: reference longitudinal acceleration calculation means 23; reference yaw-rate calculation means 14; target pitch motion setting means 15; and command value correction means 16 that corrects a braking/driving force command value and a rear-wheel steering angle command value so that vehicle body motion approximately matches reference longitudinal acceleration, reference yaw-rate and target pitch motion. The command value correction means 16 has ratio setting means 16a that sets a ratio α of magnitude of pitch moments generated by correcting the rear-wheel steering angle command value in the sum of the pitch moments generated by the correction, the command value correction means 16 performing the correction using the ratio α. The ratio setting means 16a sets the ratio α on the basis of magnitude of the pitch moments generated by correcting the braking/driving force command value and the rear-wheel steering angle command value or magnitude of the rear-wheel steering angle command value.SELECTED DRAWING: Figure 8
