  • Patent number: 11904931
    Abstract: A steering system configured to steer a vehicle includes a rotary shaft to which an operation member is coupled; a moving unit configured to move the operation member between a normal position that is a position where the operation member is operated by a driver, and a storage area located ahead of the normal position; an external force detection unit configured to detect an external force externally applied to the operation member while the operation member is moving; a determination unit configured to determine whether a direction of the external force detected by the external force detection unit is the same as a moving direction of the operation member; and a control unit configured to control operation of the steering system based on a determination result from the determination unit.

  • Patent number: 11465666
    Abstract: 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.

  • Patent number: 11377134
    Abstract: 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.

  • Patent number: 11247713
    Abstract: 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.

  • Patent number: 11214293
    Abstract: 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.

  • Patent number: 10235448
    Abstract: 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.

  • Publication number: 20160224582
    Abstract: According to a data processing method, pieces of data from files having dissimilar file structures and different formats can be combined appropriately for processing, and even a user with little knowledge can easily combine and process data. The method comprising: receiving, from a user terminal, designation of a first file and a second file, and a request to execute data processing that is related to a particular function; obtaining the first file and the second file from a memory unit; analyzing structures of the first file and the second file; combining, when there is a first element set in the first file as many elements as in a second element set the second file has, the elements of the first element set with the elements of the second element set to execute the data processing; and transmitting a result of executing the data processing to the user terminal.
