  • Patent number: 9841930
    Abstract: A storage control apparatus includes a processor. The processor is configured to store, during a normal operation mode, first data as a first logical volume in a storage section of a first virtual storage device. The first data is transmitted and received between a first host device and a physical storage device. The physical storage device stores data in a physical volume. The first virtual storage device is connected to the physical storage device during the normal operation mode. The processor is configured to serve, during a data migration mode, as a pseudo host device connected to a second virtual storage device. The pseudo host device accesses the second virtual storage device to read out second data of a second logical volume stored in the second virtual storage device. The first virtual storage device is connected to the second virtual storage device during the data migration mode.

  • Publication number: 20170349153
    Abstract: An increase in startup current supplied to a motor is suppressed at an initial stage of starting automatic braking control, while current supply to the motor is performed in a fully energized state after the automatic braking control is started. While output of the motor is increased by controlling the motor in the fully energized state so that a high braking force with high responsiveness is obtained, startup current is prevented from becoming excessive by performing high frequency control only at startup. Thus, decrease in battery voltage is minimized and thus the occurrence of malfunction is minimized in the control systems of various electrical components used in the vehicle.
