Patent number: 10821833Abstract: A vehicle power-supply unit includes a high-voltage battery, a low-voltage battery having a lower voltage than the high-voltage battery, and an inlet, and is capable of connecting a feed connector of an external power source to the inlet and supplying electric power from the external power source to a charge target which is at least one of the high-voltage battery and the low-voltage battery. The power-supply unit includes: charge control means that controls charging of the charge target; and a battery voltage sensor that detects a voltage of the low-voltage battery. If a low-voltage battery voltage value VL becomes not higher than a charge abort threshold Vabort while connecting the feed connector to the inlet and supplying electric power from the external power source to the charge target, the charge control means stops supply of electric power from the external power source to the charge target.Type: GrantFiled: April 27, 2018Date of Patent: November 3, 2020Assignee: HONDA MOTOR CO., LTD.Inventor: Daisuke Tsutsumi

Patent number: 9581992Abstract: In a conventional CAM apparatus, cutting regions and a tool axis angle by which the cutting time is minimized cannot be automatically set for a finish shape having a free formed surface shape. Accordingly, the CAM apparatus generates quadrangle-shaped patterns of cutting regions using coordinate data of a finish shape and an initial shape. Triangle-shaped cutting regions are generated for concave-convex faces of the finish shape. For cutting regions generated by subtraction by boolean operation with a subtract shape calculated by subtraction by boolean operation between the initial shape and the finish shape, the tool axis angle is set so that the tool does not interfere and the face is maximized. For other regions, the tool axis is set so as to satisfy a remainder standard and to minimize a tool path length.Type: GrantFiled: December 18, 2013Date of Patent: February 28, 2017Assignee: Mitsubishi Hitachi Power Systems, Ltd.Inventors: Takahiro Nakano, Hiroshi Arai, Reiko Inoue, Daisuke Tsutsumi, Daisuke Igarashi, Masakazu Okubo

Patent number: 9073445Abstract: A relay control system for an electric vehicle includes an electric power line, a relay, an operation member, a state sensor, a rotational speed detector, a shift position detector, and a relay disconnection permitting device. The state sensor is configured to sense that a signal circuit through which a signal related to a state of the operation member flows is changed into a disconnecting operation state. The rotational speed detector is configured to detect a rotational speed of the electric motor. The shift position detector is configured to detect a shift position of the electric vehicle. The relay disconnection permitting device permits disconnection of the relay based on the rotational speed detected by the rotational speed detector and the shift position detected by the shift position detector if the state sensor senses that the signal circuit is changed into the disconnecting operation state.Type: GrantFiled: October 23, 2012Date of Patent: July 7, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Hideaki Iwashita, Hidekazu Saito, Kosuke Tachikawa, Toru Ozawa, Daisuke Tsutsumi
