Publication number: 20240075840Abstract: A VGI system includes a plurality of BEVs, a plurality of pieces of EVSE, and a server. The server determines whether the BEV exchanges electric power with a power grid with the use of second EVSE provided in a second area, the second area being different in manner of management of power supply by the power grid from a first area where predetermined first EVSE is provided, the first EVSE being normally used by the BEV. When the server determines that the BEV exchanges electric power with the use of the second EVSE and when the second area is higher than the first area in contribution to DR in exchange of electric power by the BEV, the server grants an incentive higher than in exchange of electric power with the power grid with the use of the first EVSE.Type: ApplicationFiled: August 29, 2023Publication date: March 7, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Osamu YUMITA, Yoichi ONISHI, Toru ANDO, Ikuma SUZUKI, Yu NAGATA

Publication number: 20240067039Abstract: An operation management server manages a vehicle equipped with a battery able to store regenerated electric power. The operation management server includes: a processor that generates a message to be transmitted to the vehicle; and a storage that stores traveling histories of a plurality of vehicles. The processor estimates a transition in a power storage amount of the battery on a planned travel route of the vehicle based on a travel plan of the vehicle and the travel histories of the vehicles. The processor generates the message for proposing execution of external power supply from the battery to an outside of the vehicle before the power storage amount reaches a predetermined amount, when an estimation is made that the power storage amount will exceed the predetermined amount on the planned travel route.Type: ApplicationFiled: June 9, 2023Publication date: February 29, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Osamu YUMITA, Yoichi ONISHI, Toru ANDO, Ikuma SUZUKI, Yu NAGATA

Patent number: 10350767Abstract: An elastic member of a torque sensor includes spring portions, a first fastening portion, and a second fastening portion. The spring portions are disposed in a radial pattern between the first and second fastening portions to connect the first and second fastening portions together. The spring portions have a dimension smaller in a direction tangential to a circle centered on an rotation axis than in a direction of the radial pattern. The distance between the first fastening portion and the second fastening portion is smaller than the dimension in the direction of the radial pattern. The optical encoders are opposed on, for example, the same diameter on a circumference of a concentric circle centered on a rotation axis of the rotational displacement of the elastic member. For example, averaging output signals from a plurality of optical encoders reduces influence of disturbance, such as cross-axis force.Type: GrantFiled: November 16, 2016Date of Patent: July 16, 2019Assignee: CANON KABUSHIKI KAISHAInventor: Toru Nagata

Publication number: 20110128422Abstract: An image capturing apparatus calculates the frequency component of each pixel of a captured image and divides the pixels into pixels in a recovery region, whose frequency components are equal to or more than a predetermined threshold, and other pixels in a non-recovery region. A recovery unit performs recovery processing for each pixel in the recovery region to correct the degradation of image quality caused by the optical characteristics of the image capturing unit. The recovery processing unit does not perform recovery processing for the pixels in the non-recovery region. The image capturing apparatus reconstructs the captured image by combining the pixels in the recovery region for which the recovery processing has been performed with the pixels in the non-recovery region. This makes it possible to suppress degradation of image quality in a region which does not match a recovery filter in terms of focal length.Type: ApplicationFiled: November 19, 2010Publication date: June 2, 2011Applicant: CANON KABUSHIKI KAISHAInventor: Toru Nagata
