Patent number: 12497753Abstract: A method to shut down a motor grader is disclosed. The method comprises obtaining information that indicates the motor grader is to be shutdown. The method further includes causing a parking brake of the motor grader to be in a braked position, and a transmission of the motor grader to be in a neutral position. The method further includes causing an implement to be moved to a grounded position when the implement is not in the grounded position. The method further includes at least one of causing, via a controller, the motor grader to be shutdown, or causing, via the controller, an alert to be provided, wherein the alert includes information that, to complete the shutdown of the motor grader, the parking brake is to be in the braked position, the transmission is to be in the neutral position, and the implement is to be moved to the grounded position.Type: GrantFiled: April 18, 2024Date of Patent: December 16, 2025Assignee: Caterpillar Inc.Inventors: Jody McDiffett, Michael C. Gentle, Ethan Tevis

Publication number: 20150165970Abstract: A method of notifying an operator that a reductant tank associated with a machine is in a full state during filling of the reductant tank. The method includes receiving a signal indicative of a current level of the reductant within the reductant tank from an electronic control module of the machine. The method also includes comparing the current level of the reductant with a predetermined threshold. The method further includes determining if a full tank status of the reductant tank exists corresponding to the current level of the reductant being greater than the predetermined threshold. The method further includes triggering a notification based on the determination of the full tank status condition of the reductant tank. The notification is provided in such a manner to alert an operator positioned outside of the machine of the full tank status of the reductant tank.Type: ApplicationFiled: February 27, 2015Publication date: June 18, 2015Applicant: Caterpillar Inc.Inventors: Ethan Tevis, Matthew A.
