  • Patent number: 11865876
    Abstract: This disclosure relates to a method and system for real time prediction of tire remaining useful life using a tire digital twin. Herein, the digital twin of the tire monitors a plurality of tires while accounting for runtime as well as parking operation of tires. During runtime, tire goes through multiple operational changes, therefore, the system is configured to estimate the operational changes. The estimation is done in the form of index, which is compared with the manufacturers' recommended value. Similarly, while vehicle is parked, tire still goes through changes which play an important role in its overall health, like, long pending wheel rotation can lead to flat spot. Tire inflation can change owing to cool down effect as well as uncontrolled natural leakages. Further, these parameter indexes are clubbed together to calculate the health index of the tire, which is used to estimate the tire's current remaining useful life.

    Abstract: At a service device (102), a user interface (106) is provided via which a user submits an order request (117) to order a requested part (X) via the at least one user input device (103). Co-replacement information (116) for the requested part (X) is identified using a co-replacements database (114), and is displayed on the display. For example, a second part (Y) commonly co-replaced with requested part (X) may be identified and recommended for replacement with part (X); or, if two parts (X) and (Y) are ordered then the co-replacement information may be to recommend ordering only one of these parts. At a server hosting the database (114), the order request is received from a service device and the co-replacement information (116) for the requested part is generated using the co-replacements database (114), and the co-replacement information is sent to the service device.

  • Patent number: 11401690
    Abstract: This description provides an autonomous or semi-autonomous earth shaping vehicle that is capable of cooperatively filling earth into a fill location in a dig site. A first earth shaping vehicle configured with a hauling tool carrying a volume of earth navigates to the fill location. At the fill location, the first earth shaping vehicle navigates over a target tool path to fill earth from the hauling tool into the fill location. As the first earth shaping vehicle fills earth into the fill location, a measurement sensor coupled to the first earth shaping vehicle measures a compaction level of earth filled into the fill location. If the measured compaction level is determined to be below a threshold compaction level, the first earth shaping vehicle communicates a request for a second earth shaping vehicle configured with a compaction tool to compact earth in the fill location.

  • Patent number: 10378186
    Abstract: When a work implement is actuated in such a manner that a work point is located at each of a plurality of positions on a datum line, a first work point position computing section calculates a position of the work point at each of the plurality of positions. A calibration value computing section calculates calibration values of angle conversion parameters (?bm, ?bm, ?am, ?am, ?bk, ?bk), dimension parameters (Lbm, Lam, Lbk), and line parameters (tilt tan ?, intercept Zline) using the fact that the positions of the work point at each of the plurality of positions calculated by the first work point position computing section can satisfy a linear equation indicating a datum line. A parameter update section reflects the calibration values calculated by the calibration value computing section in computation by a corresponding computing section that is one of the angle computing section and the first work point position computing section.

  • Patent number: 10267020
    Abstract: In a display system in an excavator, a position of an upper boundary line and a position of a lower boundary line are calculated. The upper boundary line indicates a height of a top of a cross section of a display object surface. The lower boundary line indicates a height of a bottom of the cross section of the display object surface. A predetermined reference point of a display range is set based on a positional relationship in an up-and-down direction between the current position of the excavator and the upper boundary line or between the current position of the excavator and the lower boundary line. A guidance picture showing a cross section of the display object surface included in the predetermined display range as seen from a side of the excavator, and the current position of the excavator, is displayed.
