  • Publication number: 20190273454
    Abstract: A motor control device for performing sine-wave drive of a motor includes a first physical quantity detection unit, a second physical quantity detection unit, an A/D converter, and a conversion operation control unit. The first physical quantity detection unit outputs a current detection signal according to a terminal voltage of a single shunt resistor in which a three-phase current of the motor flows. The second physical quantity detection unit outputs a physical quantity detection signal corresponding to a physical quantity related to the drive of the motor. The A/D converter performs an A/D conversion of each of the current detection signal and the physical quantity detection signal. The conversion operation control unit controls an operation of the A/D converter so as to perform the A/D conversion of each of the current detection signal and the physical quantity detection signal.

  • Patent number: 10245925
    Abstract: A vehicle door structure has a door inner panel; a BL inner RF that is made of a fiber reinforced resin and that, together with the door inner panel, forms a closed cross-section structure portion; and an up-stop member that is structured to include joined portions that are joined to the BL inner RF, and a rubber stopper that is disposed further toward a vehicle transverse direction outer side than the closed cross-section structure portion. A communication hole, that communicates an interior and an exterior of the closed cross-section structure portion and through which the up-stop member is inserted, is formed in the BL inner RF. The joined portions are joined by rivets in a state of being superposed on the BL inner RF from a vehicle transverse direction inner side.

  • Patent number: 10140207
    Abstract: There is a need to provide a microcomputer capable of eliminating an external terminal for endian selection. Flash memory includes a user boot area for storing a program executed in user boot mode and corresponding endian information and a user area for storing a program executed in user mode and corresponding endian information. A data transfer circuit reads endian information stored in the user boot area or the user area in accordance with operation mode and supplies the endian information to a CPU before reset release of the CPU. Accordingly, an external terminal for endian selection can be eliminated.

  • Patent number: 9950748
    Abstract: In a battery frame, an upper panel is made of carbon fiber reinforced plastic, and first reinforcements are made of sheet metal. Head portions of rivets are disposed at the upper panel side, and a diameter dimension of the head portions is set larger than that of caulking portions of the rivets. This enables a contact surface area between the rivets and the upper panel to be larger than in cases in which the caulking portions are disposed at the upper panel side. This enables peripheral edge portions of first joint holes in the upper panel to be supported by the head portions of the rivets over a large surface area. The peripheral edge portions of the first joint holes in the upper panel are thereby suppressed from breaking and the like.
