Title:
CONTROL DEVICE, CONTROL METHOD, AND CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/149217
Kind Code:
A1
Abstract:
A control device, a control method, and a control system according to the present invention perform, immediately before a movable member comes into contact with a stopper part, a damping control for damping movement of the movable member, and, when a movement velocity of the movable member satisfies a predetermined condition, outputs a control signal to reduce the velocity of the movable member prior to the damping control. Consequently, in a steering mechanism having a motor that applies torque to a movable member relating to steering, and a stopper mechanism that has a stopper part capable of coming into contact with the movable member, and restricts a movement range of the movable member, it is possible to stably lessen impact force when the movable member comes into contact with the stopper part.
