*The present invention relates to a steering device for steering a tire (99) in a vehicle having a steer-by-wire system (90) in which a steering mechanism is mechanically separated from a steering mechanism, the steering device being provided with a steering unit (80) including a steering actuator (88) and a steering angle control device (85). The steering actuator (88) steers the tire (99) in accordance with the indicated steering angle. A steering angle control device (85) calculates a steering angle command value ([theta] * t) corresponding to an input steering angle ([theta] r) signal, and generates a signal for driving a steering actuator (88) on the basis of the steering angle command value. The steering angle control device (85) limits such that the absolute value of the steering angle speed is equal to or less than a steering angle speed limit value ([omega] tlim) set on the basis of a predetermined parameter.

    本发明涉及转向装置,在转向操纵机构与转向机构机械地分离的线控转向系统(90)的车辆中使轮胎(99)转向,该转向装置具备包含转向致动器(88)以及转向角控制装置(85)的转向单元(80)。转向致动器(88)按照被指示的转向角使轮胎(99)转向。转向角控制装置(85)计算与输入的转向操纵角(θr)信号相应的转向角指令值(θ*t),基于该转向角指令值生成驱动转向致动器(88)的信号。转向角控制装置(85)进行限制,使得转向角速度的绝对值为根据规定的参数设定的转向角速度限制值(ωt_lim)以下。
