Control device, control method, and control system

A control device, a control method, and a control system according to the present invention perform damping control for buffering the operation of a movable member immediately before the movable member comes into contact with a stopper, and output a control signal for suppressing the speed of the movable member before the damping control is performed when the speed of movement of the movable member satisfies a predetermined condition. As a result, in a steering mechanism having a motor for applying torque to a movable member related to steering, and a stopper mechanism that has a stopper section capable of coming into contact with the movable member and restricts the movement range of the movable member, the impact force when the movable member comes into contact with the stopper section can be stably mitigated. 本发明所涉及的控制装置、控制方法以及控制系统在可动部件即将与止动部抵接之前，进行缓冲可动部件的动作的阻尼控制，另一方面，在可动部件的移动速度满足了规定条件时，在进行阻尼控制之前，输出抑制可动部件的速度的控制信号。由此，在具有对与转向相关的可动部件赋予扭矩的电动机和具有能够与可动部件抵接的止动部并限制可动部件的移动范围的止动机构的转向机构中，能够稳定地缓和可动部件与止动部抵接时的冲击力。
