    • 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.
    • 车辆转向装置包括车辆转向系统和辅助转向力施加装置。 补充转向力施加装置被构造和布置成向车辆转向系统施加补充转向力以减少操作者的转向负载。 辅助转向力施加装置包括转向转矩检测部,直线驱动条件检测部,牵引抑制控制部。 所述直线行驶状态检测部被构造和配置为检测所述车辆的直线行驶状态。 牵引抑制控制部被构造和布置成通过使用基于在直线状态下检测到的转向扭矩的历史数据计算出的拉力抑制力,在取消在直线行驶状态期间赋予车辆的拉力的方向上调整辅助转向力 驾驶条件。
