Abstract: An avoidance modifier system may be configured to modify operation of a collision avoidance system associated with a machine. The avoidance modifier system may include at least one inclination sensor and a modifier system controller configured to be in communication with the collision avoidance system. The modifier system controller may be configured to receive an inclination signal from the inclination sensor and determine an inclination angle at which the machine is operating relative to level operation. The modifier system controller may be configured to determine an adjusted ground plane angle indicative of a virtual ground plane on which the machine is operating, and communicate with the collision avoidance system, such that the collision avoidance system does not activate a braking device of the machine in response to an object sensor generating an object signal indicative of detection of an object between an actual ground plane and the virtual ground plane.

Abstract: A tipping avoidance system configured to modify operation of a collision avoidance system. The tipping avoidance system may include a payload determination system configured to generate a payload signal, and a load position determination system configured to generate a load position signal. The tipping avoidance system may also include a tipping avoidance controller configured to receive the payload signal and the load position signal, and determine, based at least in part on the payload signal and the load position signal, a minimum stopping distance at or above which the machine will not tip due at least in part to deceleration of the machine from a travel speed to a stopped condition. The tipping avoidance controller may be configured to communicate with a braking controller, such that the braking controller adjusts a stop triggering distance based at least in part on the minimum stopping distance.

Abstract: A system, method, and apparatus for controlling acceleration of a machine when the machine exits a grade. The system, method, and apparatus may determine a virtual gear having a maximum speed limit equivalent that matches the speed of the machine as the machine exits the grade. The system, method, and apparatus may also deactivate an automatic retarding control (ARC) strategy, which may be activated when the machine is on the grade to reduce and limit the speed of the machine to no more than a set speed, if the ARC strategy is active as the machine exits the grade. The system, method, and apparatus may also control automatic downshift of a transmission system to the virtual gear if the ARC mode was activing during the exit from the graded surface and is now deactive.

Abstract: Operating a machine including a continuously variable transmission (CVT) includes operating an engine of the machine at a lower engine speed, receiving data indicative of an expected increase in load on the engine, and commanding increasing the engine speed responsive to the data. The engine is operated at a higher engine speed responsive to the commanded increase, with the operation at the higher engine speed being initiated proactively so as to limit retarding a ground speed of the machine. Related control logic and machine structure is also disclosed.

Abstract: A method is provided for controlling a machine having a continuously variable transmission travelling on a ground surface. The method receives signals indicative of an inclination of the ground surface and a payload carried by the machine through an inclination sensor and a payload sensor respectively. The method further includes determining a retarding capability of the machine. The method determines a maximum allowable operating speed for the machine based at least on the inclination of the ground surface, a mass of the machine, the payload carried by the machine and the retarding capability of the machine.
