A terrain-based travel assist system and method are provided for stability control in a self-propelled work vehicle such as an excavator comprising ground engaging units and at least one work implement configured for controllably working terrain. Upon selecting or determining a travel mode for the work vehicle, the respective predetermined target positions and/or operations of the at least one work implement are retrieved from data storage, corresponding to the determined travel mode. Feedback signals are received from sensors corresponding to respective current positions and/or operations of the at least one implement, and in some embodiments to a vehicle speed. Control signals are generated for automatically controlling the at least one work implement to the respective predetermined target positions and/or through the respective operations, responsive to the determined travel mode and the received feedback signals.

System and method for terrain based control of self-propelled work vehicles

A self-propelled work vehicle is provided with work state estimation and associated control techniques. The work vehicle comprises ground engaging units, a work implement configured for controllably working terrain, and various onboard sensors. A controller is functionally linked to at least the one or more onboard sensors and configured to ascertain a first parameter or operation of the work vehicle, determine a work state of the work vehicle, based at least in part on respective input signals from one or more onboard sensors, and generate a control signal for controlling at least a second parameter or operation of the work vehicle, responsive to the ascertained first parameter or operation and the determined work state. The control signals may be provided for proactive adjustments to engine speed, movements of the work implement, movements of the work vehicle itself, etc.

System and method for work state estimation and control of self-propelled work vehicles

An undercarriage clearance system includes a datastore containing undercarriage geometry data including ground clearance data of the undercarriage assembly across a lateral dimension of a wheelbase of the work vehicle; a first sensor configured to collect ground environment data within the vehicle trajectory; and a controller. The controller is configured to: receive the undercarriage geometry data from the datastore; receive the ground environment data from the first sensor; identify an obstacle within the vehicle trajectory; evaluate a height of the identified obstacle and a projected path of the obstacle within the wheelbase of the work vehicle along the vehicle trajectory relative to the undercarriage geometry data to determine an obstacle clearance expectation; and generate an alert command signal based on the determination of the obstacle clearance expectation. A display device is configured to render a display based on the alert command signal representing the obstacle clearance expectation.

Work vehicle undercarriage clearance system and method

A working machine includes an undercarriage, a main frame, a swing bearing supporting the undercarriage from the main frame, a swing motor configured to pivot the main frame on the swing bearing about a pivot axis, a boom extending from the main frame along a working direction, and a pivot angle sensor configured to provide a pivot angle signal corresponding to a pivot position of the main frame relative to the undercarriage about the pivot axis. A controller is configured to receive the pivot angle signal and to drive the swing motor automatically.
