摘要： In order to enhance the accuracy of estimation of sideslip angle β, a sideslip angle estimation apparatus calculates a first sideslip angle β2 between the direction of centrifugal force acting on the vehicle body during cornering and the lateral direction of the vehicle body based on accelerations exerted on the vehicle body and acting in two different directions. A sideslip angle between the longitudinal direction of the vehicle body and the direction of travel of the vehicle is calculated based on the calculated first sideslip angle β2.

摘要： A vehicle steering apparatus includes a vehicle steering system and a supplemental steering force applying device. The supplemental steering force applying device is configured and arranged to apply a supplemental steering force to the vehicle steering system to reduce a steering load on the operator. The supplemental steering force applying device includes a steering torque detecting section, a rectilinear driving condition detecting section, a pulling suppression control section. The rectilinear driving condition detecting section is configured and arranged to detect a rectilinear driving condition of the vehicle. The pulling suppression control section is configured and arranged to adjust the supplemental steering force in a direction canceling a pulling force imparted on the vehicle during the rectilinear driving condition by using a pulling suppression force calculated based on historical data of the steering torque detected during the rectilinear driving condition.
