摘要： 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.

摘要： Heavy equipment is designed for operation in a substantially-repetitive work cycle that includes lifting, rotating, and lowering steps. The heavy equipment includes a generator, an electrical bus, an energy storage component, and working components. The generator provides a substantially constant electrical output to the electrical bus, which is communicated to the working components. As such, the working components of the heavy equipment are driven directly or indirectly by the electrical output of the generator. The controller selectively couples the energy storage component to the electrical bus, and the energy storage component is configured to store electricity provided by the generator, and to provide electricity to the working components by way of the electrical bus. The electrical output of the generator is less than the power used by the heavy equipment during a portion of the work cycle, and the controller couples the energy storage component to the electrical bus to supplement the electrical output of the generator during the portion of the work cycle in which the electrical output of the generator is less than the power used by the working components of the heavy equipment.

摘要： Heavy equipment includes a body, an electrical bus, and working components coupled to the body and powered by electricity conveyed via the electrical bus. The heavy equipment further includes a generator set providing an electrical output to the electrical bus, an energy storage element configured to be coupled to the electrical bus, and a computerized controller coupled to the energy storage element. The computerized controller includes a logic module for coupling the energy storage element to the electrical bus in advance of a predicted increase in demand upon the electrical bus, where the increase in demand is anticipated by the computerized controller as forthcoming based upon extrapolation, at least in part, from data related to a previous operation of the heavy equipment.

摘要： A hydraulic system includes a plurality of pumps that provide pressurized fluid to a plurality of hydraulic actuators some of which work more that others. That system is controlled by producing a usage value for each of the plurality of pumps which indicates an amount that the respective pump has worked. One of the pumps is assigned to each hydraulic actuator in response to the usage values. The pumps with lower usage values are assigned to hydraulic actuators which work more, so as to equalize the use of each pump. The assignment of pumps to hydraulic actuators changes with changes in the usage values for the plurality of pumps. When a given one of the plurality of hydraulic actuators is to operate, hydraulic fluid is routed from the assigned pump to that given one of the plurality of hydraulic actuators.

摘要： The operator of a excavator sits in a seat that has a one computer monitor on the left side and another computer monitor on the right side. A control system produces first and second sets of information regarding operation of the excavator with the first set of information being particularly relevant to the digging operation. The selection of which computer monitor displays which of the first and second sets of information depends on a direction that the excavator swings between a digging site and a dumping site and that selection changes as the direction changes. This presents the first set of information on the computer monitor that is easily observable by the excavator operator during the digging operation.
摘要翻译：挖掘机的操作人员坐在一个座位上，左侧有一台电脑显示器，右侧有另一台电脑显示器。控制系统产生关于挖掘机的操作的第一和第二组信息，其中第一组信息与挖掘操作特别相关。选择哪个计算机监视器显示第一和第二组信息中的哪一个取决于挖掘机在挖掘站点和倾倒站点之间摆动的方向，并且该选择随着方向改变而改变。这表示在挖掘操作中挖掘机操作员容易观察到的计算机监视器上的第一组信息。
