Abstract:
Heavy equipment includes first and second hydraulic pumps, and first and second hydraulic actuators, where the first hydraulic actuator facilitates a first work function of the heavy equipment and the second hydraulic actuator facilitates a second work function of the heavy equipment. The heavy equipment further includes valving and a computerized controller. The valving is configured to allow the first hydraulic pump to be coupled to the first hydraulic actuator and the second hydraulic actuator, and to allow the second hydraulic pump to be coupled to the first hydraulic actuator and the second hydraulic actuator. The computerized controller is coupled to the valving, and has a logic module. The logic module provides instructions to the computerized controller to operate the valving as a function of inputs from an operator command, a sensor input, and prioritization logic associated with the first and second work functions, so as to optimize performance of the work functions facilitated by the hydraulic actuators with respect to available output of the hydraulic pumps.
