Publication number: 20240107676Abstract: A circuit module comprises a substrate module, an electronic component, and a first conductive joining member. The substrate module includes a circuit substrate having an upper main surface and a lower main surface, an insulating member covering the upper main surface of the circuit substrate, an insulating member covering the upper main surface of the circuit substrate, and a first metal pin that passes through the insulating member parallel to a vertical axis and is electrically connected to the circuit substrate. The first metal pin has a first exposed portion. The first exposed portion is exposed from the insulating member to face a right direction. A first outer electrode has a left projecting portion projecting in a left direction from the left surface. A first conductive joining member joins the first exposed portion and the left projecting portion to each other.Type: ApplicationFiled: September 18, 2023Publication date: March 28, 2024Applicant: Murata Manufacturing Co., Ltd.Inventors: Tomohiko SUGIYAMA, Junichi TAKASHIMA, Takuya NAKAGAWA, Mayu SUZUKI, Daisuke NAKASHIMA

Publication number: 20230391197Abstract: An electric vehicle diagnostic apparatus to be installed in an electric vehicle including a temperature sensor configured to detect a temperature of a drive motor or a temperature of an inverter configured to drive the drive motor includes a controller. The controller is configured to make a diagnosis of the temperature sensor. The controller is configured to perform mask processing in which the diagnosis is not made at system startup of the electric vehicle. The controller is configured to switch a length of time of the mask processing in accordance with a condition.Type: ApplicationFiled: May 17, 2023Publication date: December 7, 2023Inventors: Tomoki SHINOZAKI, Takuya TAKASHIMA, Hiroto ASAI

Publication number: 20230278568Abstract: A sensor diagnostic device for use in a vehicle including a first temperature sensor and a second temperature sensor includes a control system. The control system includes a processor and a memory communicably coupled to each other. The control system determines a sensor abnormality based on a detected temperature difference between a first detected temperature detected by the first temperature sensor and a second detected temperature detected by the second temperature sensor. After the vehicle is stopped, the control system calculates a decrease speed of the first detected temperature based on the first detected temperature, and calculate a decrease speed of the second detected temperature based on the second detected temperature, and if an absolute value of a decrease speed difference between the first and second detected temperatures is smaller than a threshold, determines whether the sensor abnormality has occurred, based on the detected temperature difference.Type: ApplicationFiled: February 9, 2023Publication date: September 7, 2023Inventors: Tomoki SHINOZAKI, Takuya TAKASHIMA, Kunihiko KURONUMA

Patent number: 11565569Abstract: A heater apparatus includes a base member, a cover member supported by the base member, a cloth member provided between the base member and the cover member to hold a heater wire, and a heater temperature sensor brought into contact with the cloth member, covered on a base member side facing the base member and a cover member side facing the cover member with the cloth member, and configured to detect a temperature of the heater wire. The cover member has a cover recessed portion recessed towards the base member in an overlapping region where the cloth member on the base member side and the cloth member on the cover member side of the heater temperature sensor overlap.Type: GrantFiled: April 4, 2019Date of Patent: January 31, 2023Assignee: SUBARU CORPORATIONInventors: Yo Masuda, Ryoma Okazumi, Isao Nakagawa, Takahiro Akaba, Takuya Takashima, Ringo Shimada, Shogo Yoshida, Hiroto Asai

Patent number: 10773569Abstract: A cooling apparatus for vehicle includes a radiator, a coolant pump, a cooling fan, first and second mode controllers, and an abnormality diagnosing controller. The radiator cools a coolant that circulates through a circulation flow channel of a cooling system. The coolant pump causes the coolant to circulate through the circulation flow channel. The cooling fan faces the radiator. The first mode controller initiates a first operation mode process upon diagnosing an abnormality of the cooling system. The first operation mode process stops the coolant pump and drives the cooling fan. The second mode controller initiates a second operation mode process after completion of the first operation mode process. The second operation mode process stops the cooling fan and drives the coolant pump. The abnormality diagnosing controller diagnoses, based on a temperature of the radiator, the abnormality of the cooling system after the initiation of the second operation mode process.Type: GrantFiled: June 23, 2017Date of Patent: September 15, 2020Assignee: SUBARU CORPORATIONInventors: Yo Masuda, Takuya Takashima

Patent number: 10443481Abstract: A cooling apparatus for vehicle includes a cooling system, a coolant pump, and a diagnostic controller. The cooling system includes a cooling circuit in which a coolant circulates. The coolant pump causes the coolant to circulate in the cooling circuit. The diagnostic controller diagnoses an abnormality of the cooling system on a basis of a coolant temperature. The diagnostic controller performs a first mode process that increases the coolant temperature by stopping the coolant pump, and a second mode process that causes the coolant temperature to fluctuate periodically by driving the coolant pump. Upon the second mode process, the diagnostic controller diagnoses that the cooling system is normal on a condition that a cycle of the fluctuation of the coolant temperature is shorter than a reference time, and diagnoses that the cooling system is abnormal on a condition that the cycle of the fluctuation is longer than the reference time.Type: GrantFiled: October 12, 2017Date of Patent: October 15, 2019Assignee: SUBARU CORPORATIONInventors: Shogo Yoshida, Takuya Takashima, Yo Masuda
