The server issues, when the CO2 free charging is performed in the vehicle, a coupon to the user of the vehicle in which the CO2 free charging is performed, the coupon being usable at a shop located around the power supply facility. When a timing to perform the CO2 free charging is included in a specific time period, the server increases the number of issued coupons and a usage value of each coupon.Type: GrantFiled: December 13, 2019Date of Patent: April 26, 2022Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, CHUBU ELECTRIC POWER CO., INC.Inventors: Makito Muramatsu, Takumi Shibano, Masashi Tanaka, Takashi Ochiai, Takeharu Fukui, Yoshihiro Takamura, Takahiro Yokogawa, Masashi Ohgashira

Patent number: 11316464Abstract: A shift range control device includes a plurality of control units provided for each of motor windings. When a motor rotation angle sensor is normal, a drive control unit controls an energization of the motor winding of its own system by using a motor rotation angle signal. When the motor rotation angle sensor has an abnormality and it is determined that an output shaft is rotating before a standby time elapses, the drive control unit does not energize the motor winding of its own system. When it is determined that the output shaft is not rotating even after the standby time has elapsed, the drive control unit controls the energization of the motor winding of its own system without using the motor rotation angle signal.Type: GrantFiled: March 1, 2021Date of Patent: April 26, 2022Assignee: DENSO CORPORATIONInventor: Koji Sakaguchi

Patent number: 11316465Abstract: A motor drive device includes a single-phase inverter that converts a direct-current voltage output from a power supply which is a battery, into an alternating-current voltage. The inverter outputs the alternating-current voltage as an applied voltage to be applied to a motor. The applied voltage is lower when the direct-current voltage is a second voltage lower than a first voltage than when the direct-current voltage is the first voltage. Consequently, a discharge current of the battery is reduced, and the motor drive device capable of reducing an increase in battery temperature can be obtained.Type: GrantFiled: March 23, 2018Date of Patent: April 26, 2022Assignee: Mitsubishi Electric CorporationInventors: Yuji Takayama, Kazunori Hatakeyama, Haruka Matsuo

Patent number: 11305752Abstract: A system for emissions mitigation for a hybrid automobile vehicle includes an automobile vehicle provided with motive power from: a battery pack; an engine; and a controller in communication with the battery pack and the engine. A threshold battery pack state-of-charge (SOC) is predetermined. A minimum battery pack SOC is less than the threshold battery pack SOC. An engine-on charge depletion (EOCD) command is issued by the controller to start the engine in an engine-catalyst light-off operation condition when the vehicle is operating using power from the battery pack and when the threshold battery pack state-of-charge (SOC) is reached to mitigate against exceeding vehicle emissions standards.Type: GrantFiled: November 1, 2019Date of Patent: April 19, 2022Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Eric D. Piper, Andrew M. Zettel, Anthony H. Heap
