Abstract: A failure prediction and notification system for a work surface that has a raised contour includes a perception sensor mounted on a machine and a controller. The controller determines an initial physical characteristic of the initial topography of the work surface adjacent the raised contour, generates an electronic map of a current topography of the work surface based at least partially on the raw data points, and determines a current physical characteristic of the current topography. The controller further determines a difference between the current physical characteristic and the initial physical characteristic, compares the difference to a characteristic difference threshold, and generates an alert upon the difference exceeding the characteristic difference threshold.

Abstract: A method is disclosed for calibrating a vehicle model used to autonomously control a machine on a worksite. The method may include measuring a first value indicative of an operating condition of the machine, predicting a second value, using the vehicle model, corresponding to the first value and indicative of the operating condition, and determining a difference between the first value and the second value. The method may also include autonomously directing the machine to a calibration site of the worksite in response to determining that the difference between the first value and the second value is greater than a predetermined threshold, wherein the calibration site is automatically selected from a plurality of locations at the worksite based on a suitability index of the calibration site.

Abstract: A method is disclosed of modifying a worksite for calibrating a vehicle model used to autonomously control a first machine on the worksite. The method may include receiving a signal from the first machine indicative of an aspect of the vehicle model in need of calibration. The method may also include determining, in response to receipt of the signal, that the worksite includes a calibration site having a characteristic corresponding to the aspect of the vehicle model, and that calibrating the aspect of the vehicle model requires modifying the characteristic of the calibration site. The method may further include autonomously modifying the characteristic of the calibration site with a second machine at the worksite, and directing the first machine to the modified calibration site for autonomous calibration of the aspect of the vehicle model.
