Abstract: A method to control a dump body of a hauling machine having a hoist cylinder, a lift energy source, a first sensor, and a second sensor, is provided. The method includes prompt of enablement of an auto dump operation and detection a dump body angle by correlating one or more signals obtained from the first sensor and the second sensor. Upon determination that the dump body angle is zero degrees, hydraulic pressure is provided to the hoist cylinder to tilt the dump body. An angular displacement rate of the hoist cylinder is detected by determination of a change in the dump body angle, with respect to time. The hydraulic pressure to the hoist cylinder is controlled based on the angular displacement rate. The hydraulic pressure is controlled to halt the tilting of the hoist cylinder upon detection that the dump body angle is equal to a pre-determined dump body angle.
