Advantages of active steering for vehicle dynamics control

摘要

Yaw and roll dynamics of vehicles can be controlled efficiently by individual wheel braking or by active steering. Both approaches are compared on the basis of physical and application considerations. Two vehicle dynamics control concepts based on active steering are summarized. One of them focuses on the attenuation of yaw disturbances on the vehicle by robust unilateral decoupling of yaw and lateral mode. The other approach aims at rollover avoidance of road vehicles. There, in continuousoperation, active steering improves the roll dynamics. In case of emergency an efficient strategy applies simultaneous steering and braking control.
