Patent number: 12036962Abstract: 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.Type: GrantFiled: November 21, 2019Date of Patent: July 16, 2024Assignee: Caterpillar SARLInventors: Andrew De Haseth, Raymond Lathan, Shinya Sono, Ian Macdonald, Rodney Menold, Timothy Schwartz, David Wisley

Patent number: 10829901Abstract: 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.Type: GrantFiled: December 13, 2017Date of Patent: November 10, 2020Assignee: Caterpillar SARLInventors: David Wisley, Michael Looney, Russell Pugh, Rodney Menold, Jonathan Moses, Tom Abel, Anthony Weltzer, Stephen Thompson

Publication number: 20180179719Abstract: 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.Type: ApplicationFiled: December 13, 2017Publication date: June 28, 2018Applicant: Caterpillar SARLInventors: David Wisley, Michael Looney, Russell Pugh, Rodney Menold, Jonathan Moses, Tom Abel, Anthony Weltzer, Stephen Thompson

Patent number: 9802524Abstract: A method for implementing an operation of a body of a machine includes receiving data indicating an operation of a positioning mode actuator to facilitate movement of the body from a first position, determining activation state of a multi-auto mode to actuate a first auto lower mode to operate a hoist system to lower the body automatically and a first auto raise mode to operate the hoist system to raise the body automatically. The method includes determining the first auto lower mode is selected according to the data indicating the operation of the positioning mode actuator, and causing a hoist system to actively lower the body from the first position to a second position and passively lower the body from the second position to a third position, independent of the activation state of the multi-auto mode.Type: GrantFiled: March 1, 2016Date of Patent: October 31, 2017Assignee: Caterpillar Inc.Inventors: Ryan Anderson, Kurt Winckler, Rodney Menold, Joel Skalet, Timothy Schwartz
