Abstract: The present disclosure relates to an excavator, a precise control method and system therefor, a vehicle terminal and a storage medium. The precise control method for the excavator comprises: presetting a plurality of work modes of the excavator, and an action rate and action coefficient corresponding to each working mode of the plurality of work modes; and performing work mode switching according to a handle input signal.

Abstract: The present disclosure relates to a method for establishing an electronic fence for an excavator, wherein the excavator includes a frame, a slewing platform rotatably mounted on the frame, a working arm mounted on the slewing platform in a pitching swinging manner, and a bucket rotatably mounted on the working arm. The working arm includes a first working arm hinged to the slewing platform and a second working arm hinged to the first working arm. An end, away from the first working arm, of the second working arm is hinged to the bucket.

Abstract: The present disclosure provides an angle determining method, device, and system. The angle determining method includes: obtaining angle data when an upper mechanism of a split machine rotates to a preset position, the angle data including a first heading angle of the upper mechanism and a second heading angle of a lower mechanism; determining a first absolute value of a difference between the first heading angle and the second heading angle; and determining an actual heading angle of the lower mechanism according to the second heading angle and determining an actual heading angle of the upper mechanism according to the second heading angle and an actual rotation angle between the upper mechanism being at the preset position and the lower mechanism, in a case where a second absolute value of a difference between the first absolute value and the actual rotation angle is greater than a first preset threshold.
