1. A method of determining the state of a carrier on a field of operation, the carrier having means comprising two oppositely disposed motive units for transporting it over the field of operation, the method comprising the steps of:

  • employing an actual track width of the motive units as a determinant, at least in part, of the state of the carrier,relating one or more potential driving modes for the carrier to respective actual track widths that result when the carrier operates in those modes,determining the driving mode in which the carrier is operating at the time its state is to be determined,applying the actual track width that corresponds to that driving mode in determining the state of the carrier, andusing the state of the carrier for controlling an operation of the carrier.
