Truck cycle segmentation monitoring system and method

An off-highway truck having a bed for hauling material, comprising:

• a frame;
• an engine associated with the frame;
• ground engaging members connected with the frame and associated with the engine, the ground engaging members allowing the frame to travel along a ground surface;
• a sensor connected to the bed, the sensor providing a signal indicative of a change in acceleration of the bed and the frame;
• and
• a cycle controller associated with the sensor, the cycle controller disposed to receive the signal and operating to monitor the signal;
• wherein the cycle controller is programmed and operates to:
• analyze the signal to determine at least a presence and a duration of a change in acceleration of the bed with respect to time;
• determine that the truck has performed a dumping operation when the signal indicates that the bed has had an increasing acceleration when pivoted towards a dumping position, followed by a decreasing acceleration when pivoted down towards a travel position;
• catalog a presence and duration of the dumping operation;
• and
• analyze the signal to determine whether discrete periods of vibration are present at the bed while the bed is in a lowered position and following a dumping segment and, when discrete periods of vibration are present when there is otherwise little to no vibration, determine that the bed is being loaded with material and catalog a pressure and duration of a loading segment.
