Abstract: Cavitation that occurs within a pump of a machine, such as truck or other work machine, can potentially damage the pump and/or other components of the machine. The machine can have a cavitation monitor configured to detect cavitation and/or cavitation damage associated with the pump based on vibration data, speed data associated with mechanical movements of the pump, and operating data associated with the machine overall. If the cavitation monitor detects cavitation and/or cavitation damage, the cavitation monitor can cause corresponding alerts to be displayed to a machine operator or other user.

Abstract: A method for adjusting a valve lash in an internal combustion engine includes receiving a first signal generated by a sensor secured to the internal combustion engine, the first signal being indicative of a closing of a valve, receiving a second signal indicative of at least one of an engine speed of the internal combustion engine or a position of a camshaft of the internal combustion engine, and automatically determining an adjusted amount of lash associated with the valve based on the received first signal and the received second signal. The method also includes comparing the adjusted amount of lash to at least one predetermined threshold, and providing, in response to determining that the adjusted amount of lash is greater than the at least one predetermined threshold, a valve lash re-adjustment notification.

Abstract: A method for managing a differential lock in a machine is provided. The method receives an operator command, by a controller, for engaging the differential lock of the machine from a user input device. The method determines, by the controller, an articulation angle of the machine in response to the operator command. The method determines, by the controller, if the articulation angle exceeds a first threshold angle. The first threshold angle is based on a ground speed of the machine The method selectively prevents, by the controller, engagement of the differential lock, if the articulation angle exceeds the first threshold angle. The method provides a notification, by the controller, of the prevention of the engagement of the differential lock based on the articulation angle exceeding the first threshold angle.

Abstract: A machine employing controllable mounts and a method for controlling such mounts based on operator input are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. As current is applied to the coils, the apparent viscosity of the rheological fluid is increased, and in so doing so is the stiffness and damping of the controllable mount. Depending on various factors, the operator may want a particular level of feedback. For example, when fine grading, the operator may want to feel every vibration and thus the controllable mounts should be as stiff as possible. The present disclosure therefore provides the operator with the ability to select the desired level of feedback.

The controller is in communication with the wheel speed sensor and the cruise control module. The controller is configured to selectively deactivate the cruise control module based, at least in part, on a comparison of the wheel speed and a localized speed of the machine near the wheel.

Abstract: A machine employing controllable mounts and a method for controlling such mounts based on machine operation are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. As current is applied to the coils, the apparent viscosity of the rheological fluid is increased, and in so doing so are the damping and stiffness properties of the controllable mount. With other operations such as roading or working on a flat surface, the feedback afforded by the mounts is not as important as operator comfort, in which case the current applied to the coils can be lowered and thus the mount can be made more relaxed. The machine of the present disclosure identifies the machine operation being performed through sensors, predictive algorithms, implement position, and operator input and sets the current and properties of the controllable mounts accordingly.
