Publication number: 20240132147Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.Type: ApplicationFiled: October 11, 2023Publication date: April 25, 2024Applicants: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Yuuta KAJISAWA, Yuji FUJITA, Yugo NAGASHIMA, Kazuma HASEGAWA, Takashi KOUDAI, Kaishi MONOBE, Kenichi ABE, Masaharu YAMASHITA, Shintaro TAKAYAMA, Kazuaki IIDA, Yasushi HORA, Yosuke YAMASHITA, Hiroki TOMIZAWA, Nobuyori NAKAJIMA, Hayaki TANABE, Toyohiro HAYASHI, Takeshi IWANA

Publication number: 20240088814Abstract: When a DC power source fails, the following controls are performed. The normal control is resumed when an inverter input voltage recovers before a standby period elapses after a power failure time. A power source relay is turned off when the standby period elapses without recovery of the voltage. The power source relay is turned on again when a power source relay off period has elapsed from a turn-off time. The normal control is resumed when the inverter input voltage recovers at the turn-on time. The normal control is resumed when the inverter input voltage recovers before the power source relay on period elapses from the turn-on time. The power source relay is turned off, and driving of the actuator is stopped, when the power source relay on period passes without recovery of the voltage.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Inventors: Hiroki TOMIZAWA, Nobuyori NAKAJIMA, Tomoaki YOSHIMI, Toyohiro HAYASHI, Yosuke YAMASHITA, Shintaro TAKAYAMA, Yuuta KAJISAWA, Yuji FUJITA

Patent number: 10795496Abstract: It is intended to provide a method for selecting a writing sheet for a touch panel pen that can accurately select a writing sheet with which the generation of unpleasant sounds during writing is suppressed. According to the method for selecting a writing sheet for a touch panel pen, a sheet satisfying condition 1-1 and condition 1-2 described below is selected as a writing sheet for a touch panel pen. <condition 1-1> Sound generated when writing is performed under predetermined conditions using a touch panel pen on the surface of a writing sheet for a touch panel pen is recorded. The sound pressure (dB/Hz) is calculated for each 1 Hz from the recorded sound by means of fast Fourier transform. The values of the dB/Hz at frequencies from 1 Hz to 20,000 Hz are normalized to have a maximum value of 100 and a minimum value of 0, and the normalized values of dB/Hz are adopted as rated sound pressures P.Type: GrantFiled: May 31, 2017Date of Patent: October 6, 2020Assignee: DAI NIPPON PRINTING CO., LTD.Inventors: Shubou Taya, Yosuke Takayama, Tomohiro Ogawa, Jun Tsujimoto
