Abstract: Monitoring the brake performance of a brake system of a machine and a control systems for performing such monitoring. The machine's brake system is monitored by detecting a brake engagement for decelerating the machine. When a brake engagement is detected, a parasitic loss decelerating the machine during the brake engagement is determined. The parasitic loss is used to predict deceleration of the machine during the brake engagement Brake performance of the brake system of the machine is processed from the predicted deceleration.

Abstract: Disclosed herein is a system and method for determining the compaction of terrain based on rolling resistance. The system comprises a work machine configured to move along a route along the terrain, a navigation system configured to generate route data indicative of the route, a sensor configured to generate operating parameter data indicative of an operating parameter of the work machine moving along the route, and a processing unit. The processing unit is configured to process the operating parameter data to generate rolling resistance data indicative of the resistance by the terrain to the movement of the work machine along the route, and to process the rolling resistance data to generate compaction data indicative of the compaction of the terrain along the route.

Abstract: A surveying device is operated to measure a surface profile of a terrain of a worksite and generate surface profile data indicative of the surface profile. A work machine is operated to move along a route over the terrain in accordance with an operating parameter and generates machine operational data indicative of the operating parameter. A navigation system determines the route and generates route data. A processing unit processes the route data, machine operational data and surface profile data to generate monitored operating condition data indicative of a monitored operating condition of the machine.

Abstract: A work machine is moved along a route over worksite terrain. Route data indicative of the route is recorded and an operating parameter data indicative of at least one operating parameter of the work machine is determined as the machine moves along the route. The operating parameter data is used to generate rolling resistance data indicative of the resistance of the terrain to the movement of the work machine as it moves along the route. Then the rolling resistance data is processed to generate compaction data indicative of the compaction of the terrain along the route.
