Publication number: 20240083259Abstract: An electric vehicle including a motor as a driving source includes: an accelerator; a pseudo shifter mimicking a gear changing operation; a pseudo clutch mimicking a clutch operation; a detector detecting an operation mode performed on each of the accelerator, pseudo shifter, and pseudo clutch by a driver, and a rotation speed of a driving wheel; a reaction force generator generating a reaction force in the pseudo shifter in response to a driver operation performed thereon; and a controller determining the reaction force. The controller includes a processor and a memory coupled thereto. The processor calculates a virtual differential rotation speed that is based on a virtual engine rotation speed, mimicking an engine rotation speed when the driving source is assumed as being an engine, and the rotation speed based on a detection result of the detector, and determines the reaction force based on the virtual differential rotation speed.Type: ApplicationFiled: September 1, 2023Publication date: March 14, 2024Applicant: SUBARU CORPORATIONInventors: Naonori IKEZAWA, Takahiro YAMAMOTO, Kiyofumi SATO, Hironao SATO, Kyohei YAMAMOTO, Hideto FUKUDA

Patent number: 9207073Abstract: An optical divider is disposed, in front of at least one of the transmitter and receiver elements, therebetween, and at least one of a transmission and reception side, and has a plurality of optical dividing pieces each having an optical deflection surface on which an angle of a detection ray is varied to a plurality of angles for dividing the detection ray toward a plurality of division areas. The optical deflection surface on at least one of the transmission and reception side is set to have a given angle, to assign at least one of the detection ray from the transmitter elements and toward the receiver elements, to a given division area, such that a combination of the transmitter and receiver elements forming one of the division areas is different from a combination of the transmitter and receiver elements forming another one of the division areas.Type: GrantFiled: November 28, 2014Date of Patent: December 8, 2015Assignee: OPTEX CO., LTD.Inventors: Takayasu Ikeda, Kiyofumi Fukuda, Kenta Shimoji, Masayuki Shimazu, Takuya Maeda

Patent number: 7030364Abstract: Sensor(s) may be such that light-projecting component(s) and light-receiving component(s) are arranged therein. Furthermore, such sensor(s) may be provided with optical path varying means for varying projected light optical path(s) and/or received light optical path(s) so as to physically vary overlapping zone(s) in which the projected light optical path(s) and the received light optical path(s) at least partially overlap. The optical path varying means may carry out adjustment of optical sensitivity by increasing the extent(s) of the overlapping zone(s) when carrying out detection with respect to zone(s) distant from such sensor(s) and/or decreasing the extent(s) of the overlapping zone(s) when carrying out detection with respect to zone(s) proximate to such sensor(s).Type: GrantFiled: November 18, 2003Date of Patent: April 18, 2006Assignee: Optex Co., Ltd.Inventors: Toshiyasu Matsuyama, Kiyofumi Fukuda, Yasuhiro Takada

Patent number: 7009168Abstract: Sensor(s) may be such that light-projecting component(s), at which light is irradiated from one or more light-projecting elements by way of lens group(s); and light-receiving component(s), at which at least a portion of light irradiated from such light-projecting component(s) is incident on one or more light-receiving elements by way of lens group(s) after having been reflected, are arrayed therein. Lens group(s) is/are divided into a plurality of lens sets comprising a plurality of lenses. A plurality of lens sets are arranged so as to be inclined in V-shaped fashion such that a plurality of lenses occupy respectively symmetric locations.Type: GrantFiled: November 18, 2003Date of Patent: March 7, 2006Assignee: Optex Co., Ltd.Inventors: Toshiyasu Matsuyama, Kiyofumi Fukuda, Yasuhiro Takada
