Patent number: 10381902Abstract: An integrated system includes a controller, a drive device, and a fastening supporting member. The controller has a controller connector. The drive device has a drive device connector which is connected to the controller connector so that the drive device is electrically coupled to the controller. Via the fastening supporting member, the controller and the drive device are maintained in an electrically coupled state in which the drive device connector is connected to the controller connector. At least part of the controller connector and the drive device connector, as viewed from a vertical direction, is disposed within an area from a first line segment which is perpendicular to a virtual line connecting a center of gravity of the controller and the fastening supporting member and which passes the center of gravity to a second line segment which is perpendicular to the virtual line and which passes the fastening supporting member.Type: GrantFiled: January 28, 2016Date of Patent: August 13, 2019Assignee: HONDA MOTOR CO., LTD.Inventors: Tadahiro Fukushima, Tsukasa Aiba, Takahiro Hagimoto, Takahide Hashimoto
