  • Patent number: 10447053
    Abstract: A terminal includes an RF-DC conversion circuit outputting DC current by converting AC current received via wireless communication into DC current, a DC-DC converter connected to an output side of RF-DC conversion circuit to convert a voltage of DC current output from RF-DC conversion circuit to a predetermined voltage, and a controller controlling connection and disconnection between RF-DC conversion circuit and DC-DC converter. Controller acquires open circuit voltage Vin_oc on an output side of RF-DC conversion circuit, which is obtained when RF-DC conversion circuit and DC-DC converter are disconnected from each other, and target voltage ?Vin_oc (0<?<1) obtained by dividing open circuit voltage Vin_oc. When RF-DC conversion circuit and DC-DC converter are connected to each other, controller performs feedback control of DC-DC converter so that an input voltage Vin on a side where DC-DC converter is connected to RF-DC conversion circuit is equal to target voltage ?Vin_oc.

  • Patent number: 10442413
    Abstract: A parking brake control apparatus 20 drives an electric motor 43B to advance a piston 39 according to an application request signal from a parking brake switch 19. The parking brake control apparatus 20 includes a running state detection portion that calculates a running state about whether a vehicle is running or stopped based on a wheel signal from a wheel speed sensor 18. When the running state cannot be calculated by the running state detection portion, the parking brake control apparatus 20 controls the electric motor 43B in such a manner that the thrust force of the piston 39 changes at a lower time rate of change than when the running state can be calculated.
