Patent number: 12179630Abstract: A degraded state estimation apparatus configured to estimate a degraded state of a battery mounted on a vehicle includes a detector, a storage, and an estimation processor. The detector detects state quantities including first, second, and third state quantities. The storage holds a maps of data including first and second maps of data. The first map of data indicates a degree of degradation of the battery based on the first and second state quantities. The second map of data indicates the degree of the degradation based on the second and third state quantities. The estimation processor estimates an amount of change in the degradation of the battery on the basis of the state quantities detected repetitively by the detector, the maps of data, and weighting coefficients each of which weights the degree of the degradation indicated by a corresponding one of the maps of data.Type: GrantFiled: April 22, 2022Date of Patent: December 31, 2024Assignee: SUBARU CORPORATIONInventors: Yusuke Okubo, Takahiro Ueki, Tatsuya Ishibashi, Isao Tsukui

Publication number: 20240361138Abstract: A processing device includes one or more processors and one or more memories coupled to the one or more processors. The one or more processors are configured to perform a process including: acquiring pattern information, which is information indicating an operation pattern of at least one traffic light that is present on a traveling route of a vehicle; predicting, based on the pattern information, a number of stops, which is a number of times the vehicle is to stop at the at least one traffic light; and predicting, based on the number of stops, a total consumption amount of an energy source of the vehicle in a case where the vehicle travels on the traveling route.Type: ApplicationFiled: July 8, 2024Publication date: October 31, 2024Inventors: Takehiko KATSURANO, Yusuke OKUBO, Shinji SAWADA, Yoshiaki MAEZAWA, Takahiro UEKI, Takahito FUJINO, Ryuya SUZUKI, Norio SUZUKI

Publication number: 20240193591Abstract: The management server includes a memory and a processor. In addition to the certificate data, the memory stores vehicle identification information for identifying the vehicle and ECU identification information for identifying an ECU mounted on the vehicle when the certificate data is issued. The processor communicates with a specific vehicle on which ECU is mounted to obtain specific vehicle identification information for identifying the specific vehicle and ECU identification information, and executes an acquisition process of transmitting, to the specific vehicle, a first command for deleting the certificate data stored in ECU in a first instance in which the combination of the specific vehicle identification information and ECU identification information acquired from the specific vehicle is not stored in the memory.Type: ApplicationFiled: September 26, 2023Publication date: June 13, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Takahiro UEKI

Publication number: 20230311640Abstract: A gas estimating unit configured to estimate an amount and a composition of a gas generated inside a secondary battery includes at least one processor and at least one memory electrically coupled to each other. The at least one processor is configured to detect a presence or absence of a gas generating period. The gas generating period is a period for which the gas is generated inside the secondary battery while the secondary battery is in one or both of an overcharging state in which the secondary battery exceeds a voltage limit and a high-temperature state in which the secondary battery exceeds a temperature limit.Type: ApplicationFiled: March 20, 2023Publication date: October 5, 2023Inventors: Takahiro UEKI, Kotaro NAKAMURA

Patent number: 11746569Abstract: A vehicle includes a charging lid, a water droplet detector, and a controller. The charging lid is configured to cover a charging port of an inlet in an openable and closable manner. The water droplet detector is configured to detect water droplets on the vehicle. The controller is configured to release a lock of the charging lid when an access key configured to wirelessly communicate with the vehicle and provide an instruction to lock or unlock a door of the vehicle is present near the vehicle or when an unlock condition for keeping the door unlocked is satisfied. The controller is configured to, in response to the water droplet detector detecting water droplets, lock the charging lid in a closed state, regardless of whether the unlock condition is satisfied.Type: GrantFiled: February 26, 2020Date of Patent: September 5, 2023Assignee: SUBARU CORPORATIONInventor: Takahiro Ueki

Publication number: 20220297570Abstract: A vehicle includes at least one processor, at least one memory, and a storage. The processor functions as a current-value acquirer that acquires a current value of a battery mounted on the vehicle, a current-value frequency distribution deriver that increments an acquisition count for one of classes, to which the current value belongs, and derives a current-value frequency distribution representing acquisition counts for the respective classes, and a current-value rate distribution deriver that transforms the acquisition counts to acquisition rates each indicating a rate of the each of the acquisition counts to a total of the acquisition counts and derives a current-value rate distribution representing the acquisition rates.Type: ApplicationFiled: March 9, 2022Publication date: September 22, 2022Inventors: Isao TSUKUI, Yusuke OKUBO, Takahiro UEKI, Tatsuya ISHIBASHI, Mami OSAWA
