Patent number: 11465666Abstract: A steering system includes: a variable mechanism that reversibly changes a configuration of an operating member between a configuration for automated driving and a configuration for manual driving, the configuration including at least one of a position, an orientation, and a shape; a variable drive source; a receiver that receives an operation of a driver; and a controller that controls the variable drive source to cause the variable mechanism to return the configuration of the operating member to the configuration for manual driving, when the receiver receives the operation of the driver in a period when the configuration of the operating member is being changed.Type: GrantFiled: March 29, 2019Date of Patent: October 11, 2022Assignee: JTEKT CORPORATIONInventors: Norihiro Ochi, Yousuke Nishimura, Yasuyuki Nozawa, Kei Kitahara, Takeshi Watanabe

Patent number: 11377134Abstract: A steering device includes: a first moving unit that moves in an axial direction along with a shaft member to which an operating member is connected; a second moving unit; a holding unit; a first screw mechanism; a second screw mechanism; a driving unit; and a transmission mechanism that transmits driving force of the driving unit to the first screw mechanism and the second screw mechanism. One of the first screw mechanism and the second screw mechanism is provided so as to operate in a forward direction when the operating member moves between a retraction region and an operation region, and reverse efficiency of that one screw mechanism is set such that when the operating member is subjected to an external force directed toward the retraction region, that one screw mechanism does not operate in a reverse direction.Type: GrantFiled: April 13, 2021Date of Patent: July 5, 2022Assignee: JTEKT CORPORATIONInventors: Takeshi Watanabe, Kunihiro Oka, Yasuyuki Nozawa, Kei Kitahara

Patent number: 11247713Abstract: A steering apparatus for use in steering a vehicle includes: a movable body to which an input device is attached, the movable body configured to move back and forth in an extend-retract direction between a first position closer to the front of the vehicle and a second position closer to the driver; an intermediate guide that guides the movable body in the extend-retract direction, and moves back and forth in the extend-retract direction; a base guide that is attached to the vehicle and guides the intermediate guide in the extend-retract direction; a first extend-retract mechanism including an extend-retract drive source that causes the intermediate guide to move back and forth relative to the base guide; and a second extend-retract mechanism that causes the movable body to move back and forth relative to the intermediate guide by using driving force of the extend-retract drive source.Type: GrantFiled: March 15, 2019Date of Patent: February 15, 2022Assignee: JTEKT CORPORATIONInventors: Yasuyuki Nozawa, Takeshi Watanabe, Norihiro Ochi, Ryoichi Tokioka, Kei Kitahara, Yousuke Nishimura

Patent number: 11214293Abstract: A steering apparatus includes a steering wheel that rotates about a first rotation axis, a folding mechanism that folds the steering wheel along the first rotation axis, a moving mechanism that moves the steering wheel between a protruding position in which the steering wheel protrudes from a dashboard of the vehicle and a stored position closer to the dashboard than the protruding position, and an electronic control unit that drives the folding mechanism and the moving mechanism. When the folded steering wheel is moved from the protruding position to the stored position, the electronic control unit drives, in advance, a drive member mounted on the vehicle so that the steering wheel is retracted relative to a body of a driver.Type: GrantFiled: September 17, 2019Date of Patent: January 4, 2022Assignee: JTEKT CORPORATIONInventors: Yousuke Nishimura, Norihiro Ochi, Takeshi Watanabe, Yasuyuki Nozawa, Kei Kitahara

Patent number: 10235448Abstract: A search string including a location name is received from a client terminal, the search string is broken down, related data of each broken down (BD) information is acquired from a website, each BD information and its related data are stored in a storage unit in association with each other. For each BD information, it is determined whether a record of the related data includes a plurality of pieces of latitude/longitude information. A mesh display flag or a pin display flag is set to the BD information in the storage unit based on a result of the determination. Polygon display processing, mesh display processing, or pin display processing on a map is executed on the related data of the BD information based on a value of the mesh display flag and a value of the pin display flag, and a result of the processing is transmitted to the client terminal.Type: GrantFiled: March 22, 2016Date of Patent: March 19, 2019Assignee: HITACHI, LTD.Inventors: Daisuke Kitou, Satoshi Yashiro, Kei Kitahara
