  • 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.

  • Publication number: 20200039485
    Abstract: A highly reliable vehicle brake system that includes an electric brake and achieves redundancy at low cost is provided. A vehicle brake system (1) includes a first control device (10) and a second control device (11) that respectively include a master controller (30), a first sub-controller (40), and a second sub-controller (41) that are connected to one another. Each of the master controller (30), the first sub-controller (40), and the second sub-controller (41) includes a braking force calculation unit that calculates braking force of electric brakes (16a to 16d), and a determination unit that compares braking force calculation results of the controllers to determine whether itself is normal. The determination unit includes an output block section that blocks, when the determination unit determines that any one of the controllers is not normal, an output of the controller that is determined to be not normal.
