Patent number: 11628736Abstract: The solar charging system according to the present embodiment includes a solar panel, a drive battery, an auxiliary system including one or more devices, and a controller that controls where to supply power generated by the solar panel. The controller determines whether the solar panel can generate power, and, upon determining that the solar panel can generate power, supplies the power from the solar panel to the auxiliary system to derive the power generated by the solar panel. Upon detecting a fact that the power generated by the solar panel is equal to or greater than a first power, the controller further supplies the power from the solar panel to the drive battery to charge the drive battery.Type: GrantFiled: October 8, 2020Date of Patent: April 18, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuma Miyamoto, Satoshi Shizuka, Akinori Kawamura, Takashi Fukai, Masahiro Takahashi

Patent number: 11198368Abstract: A vehicular charging control system using a solar panel includes: a first battery; a calculation unit that calculates a chargeable electric power amount (an amount of electric power with which the first battery can be charged until the SOC of the first battery reaches a predetermined value); a determination unit that determines whether regenerative electric power is being generated; and a control unit that controls charging of the first battery with electric power generated by the solar panel. The control unit allows the first battery to be charged with the electric power generated by the solar panel up to an upper limit set to the chargeable electric power amount when regenerative electric power is not being generated, and up to an upper limit set to an electric power amount obtained by subtracting the regenerative electric power amount from the chargeable electric power amount when regenerative electric power is being generated.Type: GrantFiled: November 4, 2019Date of Patent: December 14, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Satoshi Shizuka

Patent number: 9798658Abstract: In a first process, based on data of a FLASH status 0 area included in a first block of a flash ROM, a rewriting process including erasing, writing and verifying on blocks of the flash ROM storing a user program to be rewritten based on contents of a user program for rewriting is controlled. In a second process, the rewriting process is carried out without regard to the data of the FLASH status 0 area. In the first process, writing on the FLASH status 0 area is not carried out in the rewriting process on the first block of the flash ROM, but writing on the FLASH status 0 area is carried out based on the contents of the user program for rewriting after carrying out the rewriting process on a last block of the flash ROM.Type: GrantFiled: January 11, 2016Date of Patent: October 24, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Satoshi Shizuka

Patent number: 9720474Abstract: An electronic control unit mounted in an object includes: a rewritable memory of control and reprogramming software; a not-always-on power supply system micro-computer operating in control and reprogramming modes and connected/disconnected with a power source; and an always-on power supply system micro-computer operating in the control and reprogramming modes and constantly connected with the power source. Each micro-computer includes: a first mode determination device determining whether to operate in an on-board mode when the power source starts to supply the electric power; and a second mode determination device determining whether to operate in the reprogramming mode. The always-on power supply system micro-computer includes a first transition device that detects a change in a power supply state of the not-always-on power supply system micro-computer.Type: GrantFiled: October 9, 2014Date of Patent: August 1, 2017Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yasuhiko Harada, Shizuo Manabe, Satoshi Shizuka
