Abstract: A guidance system to assist in alignment between an electric machine and power rails from which the electric machine draws electrical power is disclosed. The power may be drawn by the electric machine from the power rails via an arm having a rotating joint and a rotation sensor that measures the level of rotation of the rotating joint. A controller may receive signals indicative of the rotation angle of the rotating joint and indicate, on a display, the direction and/or magnitude of misalignment between the electric machine and the power rails. The operator of the electric machine can observe the indication of misalignment and use that information to steer the electric machine to the left or the right to better align the electric machine to the power rails. The indication of misalignment may be overlayed on a real-time video display of a path in front of the electric machine.

Abstract: A system for controlling an auxiliary system of a work machine includes a controller including at least one memory and at least one processor. The at least one processor is configured to determine a current amount of power available at the battery system, determine a requested power consumption of the auxiliary system, and an expected power consumption of the auxiliary system, compare each of the current amount of power available with a threshold amount of power for the battery system, the requested power consumption with the current amount of power available, and the expected power consumption with the current amount of power available, and adjust, based on the comparison, an operating parameter of one or more auxiliary components of the auxiliary system to reduce power draw by the auxiliary system from the battery system.

Abstract: A machine, such as a haul truck or other work machine, has braking systems including front friction brakes on a front axle, rear friction brakes on a rear axle, and electric brakes on one or both axles. A braking controller uses factors such as a capacity of the electric brakes, a payload carried by the machine, a grade of a ground surface traveled by the machine, a temperature of the front friction brakes, and a temperature increase rate associated with the front friction brakes to dynamically determine a blended axle split associated with a braking operation to be performed by the machine. The blended axle split indicates portions of braking torque to be applied by the electric brakes on one or both axles, the front friction brakes on the front axle, and the rear friction brakes on the rear axle.
