Publication number: 20190273454Abstract: 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.Type: ApplicationFiled: May 16, 2019Publication date: September 5, 2019Inventor: Tomohiro SAKURAI

Patent number: 10140207Abstract: 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.Type: GrantFiled: January 22, 2018Date of Patent: November 27, 2018Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Mamoru Sakugawa, Tomohiro Sakurai, Katsuyoshi Watanabe, Seiji Ikari, Takashi Nasu, Tsutomu Kumagai

Patent number: 9950748Abstract: 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.Type: GrantFiled: December 10, 2014Date of Patent: April 24, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koki Ikeda, Kiyoshi Hokazono, Shinya Kamimura, Kentaro Nakamura, Shin Terada, Tomohiro Sakurai
