Abstract
A method for confirming delivery of bulk material from a bed of a dump truck based on hydraulic pressure. The dump truck has a driving device moving the bed between a rest position and a delivery position. The method generally having: using a hydraulic pressure sensor, measuring a plurality of hydraulic pressure values indicative of pressure of a hydraulic fluid of the driving device as the bed is moved; and using a controller communicatively coupled to the hydraulic pressure sensor: monitoring a slope at which at least some of the plurality of hydraulic pressure values vary over a given period of time; and generating a delivery confirmation indicative that a delivery of the bulk material has occurred based on a comparison between the monitored slope and a delivery slope threshold.
