Method for controlling anti-roll/anti-yaw of vehicles
First Claim
1. A method for providing anti-roll and an anti-yaw controls of a vehicle by controlling front and rear wheel dampers of the vehicle, said front and rear wheel dampers including left and right front wheel dampers, and left and right rear wheel dampers, and said method comprising the steps of:
- deciding whether an anti-roll control is required by comparing a roll rate of the vehicle with a predetermined threshold roll rate;
executing the anti-roll control if the roll rate is larger than the predetermined threshold roll rate;
after deciding that an anti-roll control is required and executing the anti-roll control, deciding whether an anti-yaw control is required by comparing a difference between an actual yaw rate of the vehicle and a desired yaw rate with a predetermined threshold yaw rate; and
executing the anti-yaw control if the difference between the actual yaw rate and the desired yaw rate is larger than the predetermined threshold yaw rate.

Abstract
A method for controlling roll/yaw motions of a vehicle includes the steps of deciding whether an anti-roll control is required or not by comparing a roll rate of the vehicle with a predetermined threshold roll rate, executing the anti-roll control if the roll rate is larger than the predetermined threshold roll rate, deciding whether an anti-yaw control is required or not by comparing a difference between an actual yaw rate of a vehicle and a desired yaw rate with a predetermined threshold yaw rate and executing the anti-yaw control if the difference between the actual yaw rate and the desired yaw rate is larger than the predetermined threshold yaw rate. During the anti-roll control, both right and left front wheel dampers and both right and left rear wheel dampers are hard-controlled at the same time. Further, during the anti-yaw control, both right and left front wheel dampers are hard-controlled and both right and left rear wheel dampers are soft-controlled.
