Publication number: 20240103080Abstract: A malfunction detection method detects a malfunction in an electronic control device. The electronic control device includes a normal power supply terminal connected to a normal power supply mounted on a vehicle, a starting power supply terminal connected to a starting power supply, a controller activated by supply of a normal voltage, and a wake-up circuit having a wake-up switch to open and close a power supply path from the normal power supply terminal to the controller. The wake-up circuit turns on the wake-up switch when a starting voltage input to the starting power supply terminal is equal to or greater than an ON threshold. The malfunction detection method includes determining by the controller that the wake-up switch has an ON sticking malfunction when the normal voltage is equal to or greater than a threshold and the starting voltage is less than the ON threshold.Type: ApplicationFiled: November 29, 2023Publication date: March 28, 2024Inventors: Tsuyoshi Tashima, Daisuke Kobayashi, Masaya Taki, Ryo Kano, Hisashi Kameya

Patent number: 9788411Abstract: An electronic control unit includes a substrate, an electronic component, a heat sink, a cover, a heat accumulator, and a screw. A wiring pattern is formed on the substrate. The electronic component is mounted on the substrate and generates heat upon energization thereof. The heat sink is provided on one side of the substrate in its thickness direction. The cover is made of resin and is provided on the other side of the substrate in its thickness direction. The heat accumulator is fixed to a part of the cover on the substrate-side and is in contact with a surface of the substrate on the cover-side. One end of the screw is connected to the heat sink. A central portion of the screw is inserted through a hole passing through the substrate in its thickness direction. The other end of the screw is connected to the heat accumulator.Type: GrantFiled: April 4, 2016Date of Patent: October 10, 2017Assignee: DENSO CORPORATIONInventor: Tsuyoshi Tashima

Patent number: 9555828Abstract: In an electronic control unit, high-heat-generating devices are mounted on a first surface or a second surface of a board, a heat-dissipating member is located facing the first surface of the board, and a heat-conducting member is located between the board and the heat-dissipating member. The heat-conducting member is in contact with the high-heat-generating devices to transfer heat of the high-heat-generating devices to the heat-dissipating member. A ratio of the number of the high-heat-generating devices mounted on the board to the number of the high-heat-generating devices arranged inside a first limited region of the first surface or a second limited region of the second surface is greater than a predetermined ratio. The second limited region is located at a position corresponding to the first limited region.Type: GrantFiled: December 24, 2014Date of Patent: January 31, 2017Assignee: DENSO CORPORATIONInventors: Tsuyoshi Tashima, Jyunichi Oogoshi, Takayuki Uchida, Katsuhiko Hayashi, Shinsuke Oota
