  • Patent number: 10353695
    Abstract: A software management system for a vehicle, including a vehicle and a management server, includes: an update necessity determination portion configured to determine whether or not an update is required in terms of software installed in the vehicle and related to a driving support function; and a restriction portion configured to turn on a control flag of the driving support function when it is determined that the update is required, and also configured to turn off the control flag when the update is permitted by a user and the software related to the driving support function is updated. The software management system starts to restrict an operation of the driving support function at a predetermined timing while the control flag is in an ON state, and resets the restriction at a timing when the control flag is turned off.

  • Patent number: 10323381
    Abstract: A work implement has a boom, an arm, and a bucket pivotable around a bucket axis which is a pivot axis with respect to the arm and a tilt axis orthogonal to the bucket axis. The hydraulic cylinder has the bucket pivot around the tilt axis. The regulation valve regulates an amount of supply of a hydraulic oil to be supplied to the hydraulic cylinder based on a command signal. The position sensor measures a stroke length of the hydraulic cylinder. The control unit resets the stroke length measured by the position sensor. The control unit determines proximity to a stroke end of the hydraulic cylinder, generates a command signal for increasing a degree of opening of the regulation valve in the proximity of the stroke end, and resets the stroke length measured by the position sensor while the regulation valve is open in response to the command signal.
