Patent number: 11973453Abstract: A first actuator and a second actuator each have a plurality of control calculation units provided redundantly and a plurality of motor drive units provided redundantly. In the first and the second actuators, the control calculation units of the systems paired with each other transmit and receive information to and from each other by a communication between the actuators. When a failure occurs in any system in either of the two actuators, or when a failure occurs in a communication between actuators in either system, the control calculation unit of each actuator of the system in which the failure occurred stops the motor drive control. Then, the motor drive control is continued by the control calculation unit of the normal system in both actuators.Type: GrantFiled: April 26, 2022Date of Patent: April 30, 2024Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHA, JTEKT CORPORATIONInventors: Hiroki Tomizawa, Masaharu Yamashita, Kenji Shibata, Yosuke Yamashita, Shoji Kubota, Yugo Nagashima, Yuji Fujita, Kenichi Abe

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
