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

Patent number: 11590893Abstract: A rearward camera of a vehicle electronic mirror system images a rearward view of a vehicle, and a lateral rearward camera unit images each of right and left lateral rearward views of the vehicle. A control device compresses at least one of a rearward view picture after imaging by the rearward camera and right and left lateral rearward view pictures after imaging by the lateral rearward camera unit, at least in a vehicle-width direction, and performs display on an inner mirror display. The control device changes the compression ratio of the picture in the control device, depending on at least one of a state and peripheral situation of the vehicle. Accordingly, when a vehicle rearward side including lateral rearward sides contains a site requiring an easy distance-sense grasp, it is possible to easily grasp distance sense by decreasing the compression ratio of the picture corresponding to the site.Type: GrantFiled: August 2, 2021Date of Patent: February 28, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yosuke Kubota

Patent number: 11390216Abstract: An electronic mirror system for a vehicle includes a rear imaging device, a left and right pair of side-rear imaging devices, a display device, an anomaly treatment device, memory, and a processor coupled to the memory. The processor causes a composite image in which a rear image and side-rear images are composited to be displayed, and detects an anomaly occurring at any one of the imaging devices. In a case in which an anomaly is detected, the processor generates a substitute image based on a captured image captured by another of the imaging devices, and causes the substitute image to be displayed. And, in a case in which the one of the imaging devices at which the anomaly is detected, is restored to the normal state by the anomaly treatment device, the processor causes the composite image to be displayed instead of the substitute image.Type: GrantFiled: June 15, 2020Date of Patent: July 19, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomohito Higuma, Yosuke Kubota

Patent number: 11214117Abstract: A temperature control system to be installed in an electric vehicle includes a water circuit, a coolant circuit, a radiator, a heat exchanger, a water pump, and a controller. The water circuit circulates cooling water to cool an electric device. The coolant circuit circulates a coolant to control a temperature of a cabin or battery of the electric vehicle. The radiator is disposed in the water circuit. The heat exchanger is disposed in the coolant circuit and receives heat released from the radiator through cooling air delivered from the radiator. The water pump regulates a flow rate of the cooling water circulating in the water circuit. The controller increases the number of rotations of the water pump to a greater value in a condition where an increase in temperature of the cabin or the battery is requested than in a normal condition where the increase in temperature is not requested.Type: GrantFiled: November 1, 2019Date of Patent: January 4, 2022Assignee: SUBARU CORPORATIONInventors: Nobusuke Nagaoka, Yoshihiro Nakazato, Taiki Sakai, Yosuke Kubota
