Patent number: 11685260Abstract: A vehicle includes a display device that displays information indicating an operation state of an internal combustion engine. A display control device which is a control device that controls the display device includes an acquisition unit configured to acquire the operation state of the internal combustion engine. The display control device includes a display control unit that switches information which is displayed on the display device between a warm-up indicator for notifying that warm-up of the internal combustion engine is being performed and a warm-up completion indicator for notifying that warm-up of the internal combustion engine has been completed. The display control unit is configured to prohibit switching from the warm-up completion indicator to the warm-up indicator when the warm-up completion indicator is being displayed on the display device while the internal combustion engine is operating.Type: GrantFiled: October 29, 2020Date of Patent: June 27, 2023Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kazuma Aoki, Koji Hokoi, Yusuke Furuhashi

Patent number: 11014452Abstract: An electrically driven vehicle comprises a motor; a power storage device; a first power supply device connected with a power line; a charging device configured to charge the power storage device by using electric power from an external power source; and a second power supply device configured to supply part of the electric power from the external power source to auxiliary machinery via the charging device. The electrically driven vehicle performs a charging efficiency determination process that calculates a charging efficiency as a ratio of a charging power of the power storage device to an input power of the charging device, and that determines whether the charging efficiency is lower than a predetermined efficiency. When the charging efficiency determination process determines that the charging efficiency is lower than the predetermined efficiency, the electrically driven vehicle stops the second power supply device and performs the charging efficiency determination process again.Type: GrantFiled: January 29, 2019Date of Patent: May 25, 2021Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masaru Kimura, Yusuke Furuhashi, Hidenori Yamada, Yusuke Hattori
