  • Publication number: 20210323148
    Abstract: Provided is a control device capable of controlling the operation of a control target according to a detected external force. A control device (200) includes a control unit (210-1) that compares a first external force detected by a force sensor provided in a control target and a second external force estimated on the basis of a torque detected by a torque sensor provided in an a movable portion of the control target, the movable portion enabling the force sensor to be movable, and controls the operation of the control target by correcting a torque command value on the basis of a result of the comparison.

  • Patent number: 10808840
    Abstract: A transmission control device controls a CVT installed in a vehicle. The device has, as modes for the CVT, a CVT mode M1 for changing a transmission gear ratio steplessly based on the operating state of the vehicle, and a stepped transmission mode M2 for changing the transmission gear ratio stepwise based on the operating state of the vehicle. The device includes a transmission mode switching control unit (controller) 12 for controlling switching between the CVT mode M1 and the stepped transmission mode M2 based on an actual accelerator opening. The transmission mode switching control unit (controller) 12 performs switching from the CVT mode M1 to the stepped transmission mode M2, if the actual accelerator opening reaches or exceeds a first threshold value T1 set in a plurality of stages so as to increase stepwise in accordance with an increase in a vehicle speed.

  • Publication number: 20200214779
    Abstract: A control device and a control method of a master-slave system and the master-slave system are provided. A control device, which controls an operation of a master-slave system, includes a control unit that applies, to a control system of the master-slave system, a restraint force corresponding to an operation in a desired translational or rotational direction by the master. The control unit applies, to the control system, the restraint force according to a difference between a current position or posture of the master and a reference value of a position or posture to be restrained. The control system controls the master-slave system, for example, by a bilateral control method or a unilateral control method.
