Abstract From the Canadian patent

Adaptive Payload Monitor A payload monitoring system of a work, vehicle includes a software controlled method of predicting when one additional bucketload of material will properly fill the vehicle to its rated capacity. The system calculates the actual magnitude of each bucketload of material and adds that value to the present payload to predict the future payload resulting from an additional bucketload of material. When the predicted future payload encompasses the rated capacity, the system signals the operators of both the work vehicle and the loading vehicle that one additional pass will complete the loading process.
