Publication number: 20220259822Abstract: The disclosure describes technology that is related to mobile machines performing an automated mobilization task based on a mobilization command received from an electronic device that is separate from the mobile machines. The mobile machine may receive, from the electronic device, a mobilization command that instructs relocation of the mobile machine from an initial location to a final location. The mobile machine may traverse a path on a worksite that includes a series of locations extending from the initial location of the mobile machine to the final location. Furthermore, the mobile machine may determine its present position includes the final location, and, in response, send a relocation notification to the electronic device indicating that the mobilization task is completed.Type: ApplicationFiled: February 18, 2021Publication date: August 18, 2022Applicant: Caterpillar Inc.Inventors: Gautham Subramanian, Mark William Whiting, Mark A.

Patent number: 10633805Abstract: Systems and methods for implementing a machine control system in a construction machine having an implement with an extender. The machine control system may include an acceleration sensor mounted to the implement and a processor configured to perform various operations. The operations may include determining that the extender is not moving and in response operating under a first control scheme. Operating under the first control scheme may include receiving acceleration data from the acceleration sensor, generating an estimated slope of the implement based on the acceleration data, and modifying a slope of the implement based on the first estimated slope by causing movement of at least one tow arm. The operations may also include determining that the extender is moving and in response operating under a second control scheme. Operating under the second control scheme may include maintaining the slope of the implement substantially constant.Type: GrantFiled: March 30, 2018Date of Patent: April 28, 2020Assignee: Caterpillar Trimble Control Technologies LLCInventors: Francisco Green, Tony Steinhagen, Mark Tarvin
