1. A work machine system including a leading vehicle configured to unload material into a receiving vehicle during an unloading operation, the receiving vehicle being configured to be propelled by a following vehicle, the work machine system comprising:
a receiving vehicle sensor mounted to the leading vehicle, the receiving vehicle sensor being configured to detect a cross member disposed across a material-receiving opening of the receiving vehicle and generate a sensor signal responsive to the detected cross member;
one or more processors; and
memory storing instructions executable by the one or more processors that, when executed by the one or more processors, configure the work machine system to:
identify, responsive to the sensor signal, a first offset value that is indicative of a location of the cross member relative to a first reference point on the leading vehicle;
identify a second offset value that is indicative of a location of a second reference point on the following vehicle relative to the first reference point on the leading vehicle;
identify a calibrated cross member offset value indicative of a location of the cross member relative to the second reference point on the following vehicle based on the first offset value and the second offset value; and
control the unloading operation based on the calibrated cross member offset value.
