International Classification:

B60W 10/24
E02F 9/20

US Classification:

701 22, 701 50

Abstract:

An energy system for heavy equipment having an actuator for operating a tool includes a bus, an engine, a generator, an energy storage device, and a controller. The bus is for providing electricity to the actuator as a function of operation of the tool. The engine is for providing a power output and the generator is coupled to the engine and configured to provide electricity to the bus. The energy storage device is configured to receive electricity from the bus for storage of energy, and is further configured to provide electricity to the bus to supplement the electricity provided by the generator. The controller is configured to change the power output of the engine as a function of electrical demand on the bus. In response to a change in the electrical demand, the controller is configured to change the power output of the engine at a rate that is less than a maximum capability of the engine.

International Classification:

B60W 10/24

US Classification:

701 50, 701 22, 180 65265, 180 6527, 180 65275, 180 65285, 180 6531, 318140, 903902, 903903, 903906

Abstract:

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.

International Classification:

F15B 11/17
F15B 21/02

US Classification:

60428, 60486

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.

International Classification:

B60L 15/00

US Classification:

701 22, 307 91

Abstract:

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.

E02F 9/24
G01C 9/02

Abstract:

A system for determining a position of a first component relative to a second component includes a first sensor mounted on the first component and configured to generate first position signals indicative of a position of the first component, and a reference sensor mounted on the second component and positioned adjacent the first sensor and configured to generate reference position signals indicative of a position of the second component. A controller is configured to receive the first position signals, receive the reference position signals, and determine a position of the first component relative to the second component based upon both the first position signals and the reference position signals.

Abstract:

Power supply systems and methods for controlling such systems are provided. One power supply system includes a generator set configured to provide an electrical output to an electrical bus, over which power is supplied to heavy equipment. The power supply system further includes a computerized controller configured to be coupled to an energy storage element, wherein the computerized controller is configured to couple the energy storage element to the electrical bus in advance of a predicted increase in demand upon the electrical bus to maintain a substantially constant voltage on the electrical bus during the predicted increase in demand and prevent a drop in voltage on the electrical bus that would otherwise result from the predicted increase in demand. The predicted increase in demand is anticipated by the computerized controller as forthcoming based upon extrapolation, at least in part, from data related to a past operation of the heavy equipment.
