Title:
VEHICLE MOVEMENT CONTROL DEVICE, VEHICLE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/264897
Kind Code:
A1
Abstract:
A vehicle movement control device (100) includes: a sideslip angle speed estimator (150); a yaw angle acceleration calculator (170); a roll moment calculator (110) that calculates and outputs a roll moment command value, on the basis of at least the product of the vehicle speed and an sideslip angle speed estimated value of a vehicle (1) and the product of the vehicle speed and the yaw angle acceleration calculated value, such that the roll movement and yaw movement of a turning vehicle are in tandem; and an actuator control means (130) for controlling an actuator (400), which generates roll moment, on the basis of the roll moment command value. A yaw angle acceleration of the vehicle (1) is estimated from the vehicle speed and the steering angle. The output of a yaw rate sensor provided to the vehicle (1) is differentiated to output a yaw angle acceleration actual value. The percentage of the yaw angle actual value relative to the yaw angle acceleration calculated value is set. The yaw angle acceleration calculated value is calculated from the yaw angle acceleration estimated value, the yaw angle acceleration actual value, and the percentage; and the percentage is set on the basis of the vehicle speed and the steering angle.
