Machine traction indication for remote control

A method for identifying traction reduction in a remotely operated or autonomous mobile machine, the method comprising:

• receiving target travel trajectory information of the mobile machine;
• receiving actual travel trajectory information of the mobile machine;
• detecting a reduction of traction of the mobile machine based on a difference between the target travel trajectory information and the actual travel trajectory information;
• comparing the reduction of traction with a plurality of predefined ranges, wherein each of the plurality of predefined ranges is associated with a respective risk level,
• determining an initial indication of slippage based on the reduction of traction being within a first predetermined range of the plurality of predetermined ranges;
• preemptively identifying excess traction reduction of the mobile machine, based on the initial indication of slippage, prior to the reduction of traction being within a second predetermined range of the plurality of predetermined ranges;
• and
• displaying an alert indicating the excess traction reduction.

A system for identifying reduction in traction of a machine at a worksite, the system comprising:

• a remotely operated mobile machine;
• a remote operator station comprising a user interface;
• and
• a controller for detecting slippage of the mobile machine due to a traction-reducing condition of the ground surface, the controller configured to:
• receive target travel trajectory information of the mobile machine;
• receive actual travel trajectory information of the mobile machine;
• detect a reduction of traction of the mobile machine based on a difference between the target travel trajectory information and the actual travel trajectory information;
• compare the reduction of traction with a plurality of predefined ranges, wherein each of the plurality of predefined ranges is associated with a respective risk level,
• determine an initial indication of slippage based on the reduction of traction being within a first predetermined range of the plurality of predetermined ranges;
• preemptively identify excess traction reduction of the mobile machine, based on the initial indication of slippage, prior to the reduction of traction being within a second predetermined range of the plurality of predetermined ranges;
• and
• display an alert indicating the excess traction reduction on the user interface.
