Access control to power machine functions

Abstract

The control system of a power machine may be configured to allow certain power machine functions based on a wireless connection with a mobile device. For example, the power machine may operate in a start mode that provides the operator with limited functions (e.g., engine power, but no workgroup actuators). Subsequently, access to additional power machine functions (e.g., full functionality) may be allowed based on establishing a wireless connection to a mobile device corresponding to the operating profile for the power machine.

[0003] The foregoing description merely provides general background technical information of the present invention and is not intended to help determine the scope of the claimed invention. The problem to be solved

[0004] The present invention relates to activating or deactivating power machine functions during the power machine startup process. means of solving the problem

[0005] Examples of the subject matter disclosed in the present invention may use a wireless connection between a mobile device and a power machine to provide access to specific power machine functions. In some examples, this allows the operator to perform specific operations under a limited function mode until a connection is established between the power machine and the authorized operator's mobile device. The mobile device may sometimes be associated with a corresponding operating profile, and the power machine may perform operations based on that operating profile (e.g., switching to a full function mode to allow full operation of all power machine functions).

[0006] According to some aspects of the present invention, a control system for a power machine is provided. The control system may include an input device and a control device operably connected to a power source of the power machine. The control device may be configured to enable the operation of the power source of the power machine based on the reception of a signal from the input device (e.g., due to manual operation). After receiving a signal from the input device, the control device may restrict the operation of one or more power machine functions until a wireless connection is established between a mobile device corresponding to the operating profile of the power machine and the controller.

[0007] In some examples, one or more power machine functions whose operation is restricted may include one or more of the operation of a traction element or the operation of a work element (e.g., a work group element).

[0008] According to some aspects of the present invention, a method for operating a power machine using a user input interface is provided. According to the method, upon receiving an initial user input to activate a power source of the power machine, the power machine may be placed in a start mode. Based on the placement of the power machine in the start mode, limited access to power machine functions may be provided in accordance with the authorization of the start mode. The method further comprises the steps of searching for one or more mobile devices through a controller communicating with the user input interface, establishing a wireless connection between the mobile device and the power machine to identify an association between the mobile device and the power machine's operating profile, and, based on the step of identifying the association between the mobile device and the operating profile, allowing access to additional power machine functions corresponding to the operating profile.

[0009] In some examples, permission for the start mode may include the operation of the power source of the power machine, but may not include the operation of one or more work elements (e.g., traction or work group elements) of the power machine. In some examples, additional power machine functions that are permitted access are distinguished from the operation of the power source of the power machine and may include one or more of the operation of a traction element or the operation of a work element (e.g., work group elements). In some examples, additional power machine functions may include the entire power machine function. In some examples, the mobile device may include one of a mobile phone, tablet, laptop, or personal digital assistant.

[0010] According to some aspects of the present invention, a power machine is provided. The power machine includes a power source, a driver station, and a user input interface within the driver station comprising an input device configured to receive input for activating the power source by a driver within the driver station. The power machine may further include one or more traction elements configured to move the power machine, one or more work elements configured to operate for work using power from the power source, and a control system. The control system may be configured to activate the power source based on a signal from the input device. After activating the power source, the control system may be further configured as follows: initially providing limited access to power machine functions; establishing a wireless connection with a mobile device corresponding to a driving profile; and, after initially providing limited access to power machine functions based on the wireless connection establishment, providing access to one or more additional power machine functions based on the driving profile.

[0011] In some examples, the control system is configured to identify potential wireless connections with multiple mobile devices, including the mobile device, before establishing a wireless connection with the mobile device; and to prioritize establishing a wireless connection with the mobile device based on one or more of proximity, signal strength, or a predetermined priority list. In some examples, the user input interface may include a display configured to receive an activation code. The control system may be configured to bypass the reception of the activation code via the display based on the establishment of a wireless connection with the mobile device.

[0012] The summary and abstract of the present invention are provided to explain concepts in a simplified form and are further disclosed in the detailed description below. The summary of the present invention is not intended to specify the core or essential technologies described in the claims, nor is it to be used as an aid in determining the scope of the subject matter claimed in the present invention. Effects of the invention

[0013] Some examples of the disclosed technology of the present invention may provide improved starting procedures for power machines, improved access management for specific power machine functions, or improved (e.g., automated) configuration of a power machine system based on operator priority or other operator profile information (e.g., function authorization). For example, in some embodiments, a control device may be configured to establish a wireless connection with a mobile device to determine appropriate authorization that enables corresponding selection of relevant power machine functions (i.e., allowing access and control). Thus, for example, the power machine may be configured to automatically allow specific (e.g., all) power machine operations to authorized users and to execute these operations according to appropriate operation priority (e.g., customized response to control input) without requiring the operator to use a mechanical key or manually connect to the control system to identify and prove appropriate authorization. Thus, some examples may help prevent unauthorized access to power machine functions while simplifying access for authorized users and general starting procedures. Brief explanation of the drawing

Specific details for implementing the invention

[0015] The concepts disclosed in the present invention are described and illustrated with reference to the embodiments. However, these concepts are not limited to the details of the configuration and arrangement of components of the illustrated embodiments and may be implemented or practiced in various other ways. The terminology of the present invention is used for the purpose of describing the invention and should not be construed as restrictive. Words such as "including," "comprising," and "having" and their variations used in the present invention mean including the listed items, their equivalents, as well as additional items.

[0016] The terms "initialization process" or "computer initialization process" as used in this invention refer to the operation of preparing the device for normal operation (e.g., execution of BIOS or other startup procedures, activation of touchscreens or other input devices, etc.) when the power source of the computerized device is turned on. Likewise, "startup process" refers to the operation of a power machine (e.g., traction and work operations) to prepare the power machine for operation from a powered state, starting from a powered state.

[0017] Furthermore, as used in the present invention, "power machine function" generally refers to the movement and power-based operation of a power machine, such as the operation of a power source (e.g., engine or battery), a power conversion system that converts the output from the power source into a form usable by a work element, a traction element capable of moving a work element (e.g., lift arm or other device), and the operation of other work elements such as other actuators. "Power machine function" may be distinguished from "operating system function," which specifically refers to the operation of a display screen or other input / output device for a control system, the operation of a computer-based security system (e.g., locking system), and the general operation of other electronic control devices (e.g., hub controller). However, certain power machine functions may necessarily include or depend on operating system functions, including the electronic control of hydraulic equipment, user input interfaces (e.g., displays), sensors, switches, actuators, and signaling devices.

[0018] Furthermore, as used in the present invention, the operation of a power machine having "limited" power machine functions refers to the operation of a power machine that accesses only a subset of possible power machine functions. In contrast, the operation of a power machine having "full (complete)" power machine functions refers to the operation of a power machine in which power can be used without limitation for all power machine functions (i.e., normal power machine operation). Generally, operation with limited power machine functions may include operation with completely limited functions (i.e., no power machine functions are allowed) or operation with partially limited functions (i.e., some functions are allowed, as in the non-limiting example below).

[0019] In some cases, limited power machine functions may include system operations for non-working functions only, including the operation of input devices (e.g., joysticks, push buttons, or touchscreen displays), radios, and indoor climate control systems. In some cases, limited power machine functions may be provided to the power machine even while the power source (e.g., the power machine's engine) is in operation. For example, the power source may be activated, but a user permitted to access limited power machine functions may not allow power to be transmitted by the power source for the operation of a working element or a traction element.

[0020] Additionally, the phrase “mobile device” as used in the present invention means a mobile phone (e.g., feature phone or smartphone), a tablet, a laptop, a personal digital assistant, or any other mobile device configured for wireless communication and individually electronically identifiable via wireless communication (e.g., Wi-Fi (e.g., 2.4 GHz, 4G, 5G, etc.) and communication via Bluetooth protocols) (Bluetooth is a registered trademark of Bluetooth SIG, Inc. in the United States or other jurisdictions).

[0021] Additionally, the term "physical key" as used in this document generally refers to a traditional key or key fob made of metal, plastic, or a combination thereof, which can be used to access the operator's area of ​​a power machine or to start the machine. In this regard, a "mechanical" physical key may be configured to mechanically engage the lock of other components, such as a key switch on a power machine door or a user input panel.

[0022] Additionally, the term "operating profile" as used in the present invention refers to a stored record representing one or more permissions, default settings, or other attributes related to operating functions. For example, some operating profiles may include settings representing various power functions (e.g., functions related to traction systems, specific work group actuators, geographical boundaries, etc.), settings defining the operating default settings of a specific operator (e.g., cab / comfort settings, response characteristics of specific actuators, etc.), or settings characterizing the response or permission for the operation of power machinery.

[0023] In conventional designs, power machines may be equipped to provide control devices that control various functions, including access to and control of power from a power source (e.g., engine starting or operating capability), actuators for traction operations (e.g., operation for terrain movement), work group actuators for work operations (e.g., operation of hydraulic actuators for non-mobile activities), convenience and other operating settings (e.g., climate control). Accordingly, power machines generally include various control devices that control various functions, including one or more operator interfaces configured to receive operator input.

[0024] Some examples of the disclosed technology of the present invention may provide improved starting procedures for power machines, improved access management for specific power machine functions, or improved (e.g., automated) configuration of a power machine system based on operator priority or other operator profile information (e.g., function authorization). For example, in some embodiments, a control device may be configured to establish a wireless connection with a mobile device to determine appropriate authorization that enables corresponding selection of relevant power machine functions (i.e., allowing access and control). Thus, for example, the power machine may be configured to automatically allow specific (e.g., all) power machine operations to authorized users and to execute these operations according to appropriate operation priority (e.g., customized response to control input) without requiring the operator to use a mechanical key or manually connect to the control system to identify and prove appropriate authorization. Thus, some examples may help prevent unauthorized access to power machine functions while simplifying access for authorized users and general starting procedures.

[0025] In some instances, limited power machine functions may be provided during the start process before the mobile device is used to authorize specific power machine operations. For example, the operator may initiate an initialization process for the power machine's control system (e.g., turning on the touchscreen) or initiate a start process for the power machine's power source (e.g., pressing the "Start Engine" button). In some cases, specific initialization (or start) operations may be executed accordingly, but full functionality and operation of the power machine may not be permitted initially. That is, the operator may be allowed access only to limited power machine functions during the power machine's start mode.

[0026] As part of the start operation or at other times, the control system may detect and establish a wireless connection with one or more mobile devices and allow access to additional power machine functions based on the established connection. For example, after the operator starts the engine or input interface (e.g., touchscreen), communication may be established via a wireless connection between the power machine's control system and the operator's mobile device, which was previously connected to the control system (e.g., paired with the control system using the Bluetooth protocol). Once the mobile device is paired with the control system, the operator pairing the mobile device may set a list of operation profiles available to the power machine when it is subsequently connected to a specific mobile device, for example, by excluding some of the available operation profiles. The operation profiles available to the corresponding mobile device are tracked by the power machine's control system. In some examples, the previously associated mobile device detects and establishes communication with the control system. In some examples, the control system detects and establishes communication with the previously associated mobile device. Once this communication is established, the control system allows the power machine to operate according to one of the previously defined operation profiles selected by the control system. For example, once a connection is established between a mobile device and an operating profile, the control system may allow additional power machine functions (e.g., full power machine functions) for the user based on the operating profile. The operating profile may be a default operating profile, or once communication is established, the operator may select from multiple operating profiles available to the operator by selecting one from a list provided to the operator.However, during startup operations and before a connection is established between the mobile device and the operating profile, the control system may allow the user limited power machine functions (e.g., no functions allowed, functions including only engine operation, functions including the operation of the engine and HVAC equipment, etc.). Likewise, if the connected mobile device is not connected to an operating profile with authorized access rights (or is not connected to an operating profile at all), the control system may continue to provide access only to limited power machine functions until appropriate authorization is obtained or can be verified from the operator. In some examples, if the operator takes additional steps, such as manually entering a passcode on the display or using a physical key, the operator may activate the full functions of the control system on the power machine even if a wireless connection is not established between the control system and the mobile device.

[0027] In some cases (as mentioned above), the computerized device on the power machine can automatically initiate the search for and establishment of a wireless connection with a mobile device during start mode (e.g., during the start process prior to authorization verification). For example, an initialization input from the operator (e.g., "Start engine") can cause the control system to automatically search for nearby mobile devices and attempt to establish a wireless connection accordingly. Therefore, for example, in some cases, the start operation can proceed relatively smoothly with minimal manual input from the operator. Additionally, as generally mentioned above, certain power machine functions may be available to the operator even before wireless authentication is completed. As mentioned above, in some other cases, when the power machine is supplied with power in start mode, the power machine's computerized device can be located by the mobile device.

[0028] In another example, depending on the permissions specified by the power machine's control system for the start mode, a wide range of power machine functions may be provided during start. For example, some start modes may allow the power machine's engine to start but may not allow the operator to command the operation of the power conversion system for traction or work operations. As yet another example, some start modes may allow access to some operations but not others (e.g., may allow commanded movement only for a subset of available actuators).

[0029] These concepts can be implemented in various power machines as described below. A representative power machine capable of realizing the embodiment is illustrated in the diagram of FIG. 1, and one example of such a power machine is illustrated in FIG. 2 and FIG. 3 and described below before the embodiment is invented. For the sake of brevity in the description of the invention, only one power machine is illustrated and described as a representative power machine. However, as mentioned above, the following embodiment can be implemented in any of a number of power machines, including a power machine of a different form than the representative power machine illustrated in FIG. 2 and FIG. 3. For the purposes of the invention, a power machine comprises a frame, at least one work element, and a power source capable of providing power to the work element to perform the work. One type of power machine is a self-propelled work vehicle. A self-propelled work vehicle is a type of power machine and comprises a frame, a work element, and a power source capable of supplying power to the work element. At least one work element is a motive system that moves the power machine under power.

[0030] FIG. 1 illustrates a block diagram showing a basic system of a power machine (100) into which the embodiments described below may be advantageously inserted and which may be any of a number of different types of power machines. The block diagram of FIG. 1 identifies the various systems of the power machine (100) and the relationships between the various components and systems. As previously stated, at the most basic level, for the purposes of the present invention, the power machine comprises a frame, a power source, and a work element. The power machine (100) has a frame (110), a power source (120), and a work element (130). Since the power machine (100) illustrated in FIG. 1 is a self-propelled work vehicle, it also has a traction element (140), which is itself a work element, provided to move the power machine over a support surface, and a driver station (150) that provides a driving position to control the work element of the power machine. A control system (160) is provided to interact with other systems to perform various tasks, at least partially, in response to control signals provided by the driver.

[0031] Certain work vehicles have work elements capable of performing dedicated tasks. For example, some work vehicles have a lift arm to which a tool, such as a bucket, is attached by a pinning arrangement. The work element, i.e., the lift arm, can be manipulated so that the tool is positioned to perform the task. In some cases, the tool can be positioned relative to the work element, such as as the bucket rotates relative to the lift arm, to position the tool. Under normal operation of such work vehicles, the bucket is attached and used. Such work vehicles can accommodate other tools by disassembling the tool / work element combination and reassembling the other tool in place of the original bucket. Other work vehicles are intended to be used with a wide variety of tools and have a tool interface such as the tool interface (170) shown in FIG. 1. Most basically, the tool interface (170) is a connecting device between the frame (110) or work element (130) and the tool, which can be simple, such as a connection point that attaches the tool directly to the frame (110) or work element (130), or more complex, as described below.

[0032] In some power machines, the tool interface (170) may include a tool carrier, which is a physical assembly movably attached to a work element. The tool carrier has engagement features and locking features for receiving and securing multiple different tools to the work element. One characteristic of such a tool carrier is that once a tool is attached to the carrier, the carrier is secured to the tool (i.e., not movable relative to the tool), and when the tool carrier moves relative to the work element, the tool moves with the tool carrier. As used herein, the tool carrier is not merely a pivotable connection point, but a special dedicated device intended to be received and secured to various tools. The tool carrier itself may be mounted on a work element (130), such as a lift arm or frame (110). The tool interface (170) may also include one or more power sources for providing power to one or more work elements of the tool. Some power machines may have multiple work elements having tool interfaces, and each of these may have a tool carrier for receiving tools, although this is not strictly necessary. Some other power machines may have a single work element with multiple tool interfaces, and the single work element may accommodate multiple tools simultaneously. Each of these tool interfaces is not strictly necessary but has a single tool carrier.

[0033] The frame (110) includes a physical assembly capable of supporting various other components attached thereto or positioned thereon. The frame (110) may include several individual components. Some power machines have a rigid frame, meaning that no part of the frame is movable relative to another part of the frame. Other power machines have at least one part that is movable relative to another part of the frame. For example, an excavator may have an upper frame that rotates relative to a lower frame. Other work vehicles have an articulated frame in which a part of the frame pivots relative to another part to achieve steering functionality.

[0034] The frame (110) supports a power source (120) configured to provide power to one or more work elements (130) including one or more traction elements (140), as well as to provide power to a tool attached via a tool interface (170) in some examples. Power from the power source (120) may be provided directly to any of the work elements (130), traction elements (140), and tool interface (170). Alternatively, power from the power source (120) may be provided to a control system (160), which selectively provides power to components capable of performing work functions using power sequentially. A power source for a power machine includes an engine, such as an internal combustion engine, and a power conversion system, such as a mechanical transmission or hydraulic system, capable of converting rotational output from the engine into a form of power usable by the work elements. Other types of power sources, including combinations with power sources generally known as power sources or hybrid power sources, may be integrated into the power machine.

[0035] FIG. 1 illustrates a single work element designated as a work element (130), but various power machines may have any number of work elements. Work elements are typically attached to the frame of the power machine and are movable relative to the frame when performing work. Additionally, traction elements (140) are a special case of work elements in that their function is generally to move the power machine (100) over a support surface. Traction elements (140) are shown separately from work elements (130) because many power machines have additional work elements other than traction elements, though not always. A power machine may have any number of traction elements, some or all of which may receive power from a power source (120) to propel the power machine (100). Traction elements may be, for example, a track assembly, wheels attached to an axle, etc. The traction element may be mounted on the frame such that the movement of the traction element is limited to rotation around the axle (steering is achieved by skidding), or alternatively, the traction element may be pivotably mounted on the frame such that steering is achieved by pivoting relative to the frame.

[0036] The power machine (100) includes a driver station (150) that includes an operating position in which a driver can control the operation of the power machine. In some power machines, the driver station (150) is defined by a closed or partially closed driver station. Some power machines in which embodiments of the present invention can be realized may not have a driver station or operating area of ​​the type described above. For example, a walk-behind loader may not have a driver station or operating area, but rather may have an operating position that functions as a driver station to properly operate the power machine. More broadly, power machines other than work vehicles may have a driver station that is not necessarily similar to the operating position and operating area mentioned above. Furthermore, some power machines such as the power machine (100) and others may be operated remotely (i.e., from a remotely located driver station) instead of or in addition to a driver station on or adjacent to the power machine, regardless of whether they have an operating area or operating position. At least some of the operator control functions of the power machine may include an application that can operate from an operating position connected to a tool connected to the power machine. Alternatively, for some power machines, a remote control device capable of controlling at least some of the operator control functions on the power machine may be provided (i.e., remote from the power machine and any tool coupled to the power machine).

[0037] FIGS. 2 and 3 illustrate a loader (200), which is a specific example of the power machine illustrated in FIG. 1, to which the embodiment described below may be advantageously utilized. The loader (200) is a skid-steer loader, having a traction element (in this case, four wheels) mounted to the frame of the loader by a rigid axle. Here, "rigid axle" means that the skid-steer loader (200) does not have any traction element that can be rotated or steered to achieve a turn of the loader. Instead, the skid-steer loader has a drive system that independently powers one or more traction elements on each side of the loader, and by providing different traction signals to each side, the machine tends to slide over a support surface. Such varying signals include providing power to traction element(s) on one side of the loader to move the loader forward and providing power to traction element(s) on the other side to move the loader in the reverse direction, and may pivot the loader around a center radius within the loader's own footprint. The term "skid-steer" typically refers to a loader having slip steering with wheels as traction elements, as described above. However, it should be noted that many track loaders also perform pivoting via skidding and are technically skid-steer loaders even without wheels. Unless otherwise stated for the purposes of the present invention, the term skid-steer should not be limited to loaders having wheels as traction elements. Accordingly, while some exemplary power machines discussed in the present invention have been presented as skid-steer power machines, some examples disclosed in the present invention may be realized in various other power machines. For example, some examples can be realized in small loaders or small excavators that do not perform rotation through skidding.

[0038] The loader (200) is a specific example of the power machine (100) broadly illustrated in FIG. 1 and described above. Accordingly, the features of the loader (200) described below use reference numerals similar to those used in FIG. 1. For example, the loader (200) is described as having a frame (210) just as the power machine (100) has a frame (110). The skid-steer loader (200) described herein is intended to provide a reference to the environment in which the embodiments described below regarding the track assembly and the mounting element for mounting the track assembly to the power machine may be implemented. The loader (200) is not essential to the embodiments disclosed herein and should therefore not be considered to be particularly limited to the description of features that may or may not be included in the power machine other than the loader (200) in which the embodiments described below can be realized. Unless specifically noted otherwise, the embodiments described below may be implemented in various power machines, and the loader (200) is just one of such power machines. For example, part or all of the invention described below may be realized in many different types of work vehicles, such as various other loaders, excavators, trenchers, and dozers, for example.

[0039] The loader (200) includes a frame (210) that supports a power system (220) capable of generating or providing power to operate various functions on the power machine. The power system (220) is shown in the form of a block diagram but is located within the frame (210). The frame (210) also supports a work element in the form of a lift arm assembly (230) that is powered by the power system (220) to perform various tasks. If the loader (200) is a work vehicle, the frame (210) also supports a traction system (240) that propels the power machine over a support surface and is powered by the power system (220). The lift arm assembly (230) in turn supports a tool interface (270) that includes a tool carrier (272) capable of receiving and securing various tools on the loader (200) to perform various tasks, and a power coupler (274) to which the tool can be coupled to selectively provide power to the tool that can be connected to the loader. The power coupler (274) may provide a hydraulic source, a power source, or both. The loader (200) includes a driver station (250) that defines a driver station (255) in which the driver can operate various control devices (260) to enable the power machine to perform various work functions, including various work functions. The driver station (250) may pivot backward around an axis extending through a mount (254) and, if maintenance and repair are required, provide access to power system components.

[0040] The driver station (255) includes a plurality of driver input devices, including a control lever (260) that can be operated by the driver to control the driver seat (258) and various machine functions. The driver input devices may include buttons, switches, levers, sliders, pedals, etc., and may be stand-alone devices such as hand-operated levers or foot pedals, or may be integrated into hand grips or display panels, and may include program input devices. Operation of the driver input devices may generate signals in the form of electrical signals, hydraulic signals, and / or mechanical signals. Signals generated in response to the driver input devices are provided to various components of the power machine to control various functions of the power machine. Functions controlled by the driver input devices of the power machine (100) include the control of a traction element (219), a lift arm assembly (230), and a tool carrier (272), and provide signals to any tool that can be operably coupled to the tool.

[0041] The loader may include a human-machine interface comprising a display device provided at the operator station (250) to provide a display of information related to the operation of the power machine in a form perceptible to the operator, such as, for example, audible and / or visual display. Auditory display may appear in the form of buzzers, bells, or verbal communication. Visual display may appear in the form of graphs, lights, icons, gauges, alphabetic characters, etc. The display may provide dedicated displays such as warning lights or gauges, or may be dynamic to provide programmable information, such as programmable display devices including monitors of various sizes and functions. The display device may provide diagnostic information, troubleshooting information, command information, and various types of information to assist the operator in the power machine or tools connected to the power machine. Other information that can be used by the operator may also be provided. Other power machines, such as work-behind loaders, may not have an operator station, operating area, or seat. The operating position of such a loader is generally defined as the position most suitable for the operator to operate the operator input device.

[0042] Various power machines that include or interact with the concept of the present invention described below may have various other frame components that support various working elements. The components of the frame (210) of the present invention are illustrated for the purposes of the invention, and the frame (210) is not the only form of the frame of the power machine in which the concept of the present invention is implemented. The frame (210) of the loader (200) includes an undercarriage or lower frame (211) and a main frame or upper frame (212) supported by the undercarriage. In some embodiments, the main frame (212) of the loader (200) is attached to the undercarriage (211) by means such as welding or fasteners between the undercarriage and the main frame. Alternatively, the main frame and the undercarriage may be formed integrally. The main frame (212) includes a pair of upright members (214A; 214B) located on both sides facing the rear of the main frame, supporting the lift arm assembly (230), and to which the lift arm assembly (230) is pivotally attached. The lift arm assembly (230) is pinned to each of the upright members (214A; 214B) as illustrated. For the purposes of the present invention, the combination of the mounting members on the upright members (214A; 214B), the lift arm assembly (230), and the mounting hardware (including a pin for securing the lift arm assembly to the main frame (212)) is collectively referred to as a joint (216A; 216B) (one located on each of the upright members (214)). Joints (216A; 216B) are arranged along the axle (218) and, as described below, allow the lift arm assembly to pivot about the axle (218) relative to the frame (210). Other power machines may not include uprights on both sides of the frame, or may not have a lift arm assembly that can be mounted on uprights on both sides toward the rear of the frame. For example, some power machines may have a single arm mounted on a single side of the power machine or on the front or rear end of the power machine.Other machines may have multiple working elements including multiple lift arms, each of which is mounted to the machine in its own unique structure. The frame (210) also supports a pair of traction elements in the form of wheels (219A-D) on both sides of the loader (200).

[0043] The lift arm assembly (230) illustrated in FIGS. 2 and 3 is an example of one of many different types of lift arm assemblies that can be mounted on a power machine, such as a loader (200) or other power machine, to realize an embodiment of the present invention. The lift arm assembly (230) is known as a vertical lift arm, meaning that the lift arm assembly (230) is movable along a lift path (237) that generally forms a vertical path relative to the frame (210) under the control of the loader (200) (i.e., the lift arm assembly can be raised and lowered). Different lift arm assemblies may have different geometries and may be coupled to the frame of the loader in various ways to provide a lift path different from the radial path of the lift arm assembly (230). For example, some lift paths in different loaders provide a radial lift path. Different lift arm assemblies may have an extendable or telescoping portion. Other power machines may have multiple lift arm assemblies attached to their frames, and each lift arm assembly is independent of the others. Unless specifically stated otherwise in the invention, the concept of the invention as described in the detailed description is not limited to the form or number of lift arm assemblies coupled to a particular power machine.

[0044] The lift arm assembly (230) has a pair of lift arms (234) positioned on opposite sides of the frame (210). In the lowered position shown in FIG. 2, the first end of each lift arm (234) is pivotally connected to the power machine at the joint (216), and the second end (232B) of each lift arm is positioned toward the front of the frame (210). The joint (216) is positioned toward the rear of the loader (200), and the lift arm extends along the side of the frame (210). The lift path (237) is defined by the path of the second end (232B) of the lift arm (234) as the lift arm assembly (23) moves between a minimum and a maximum height.

[0045] Each lift arm (234) has a first portion (234A) of each lift arm (234) pivotally connected to the frame (210) at one of the joints (216), and a second portion (234B) extending from the connection to the first portion (234A) to a second end (232B) of the lift arm assembly (230). Each lift arm (234) is connected to a cross member (236) attached to the first portion (234A). The cross member (236) provides increased structural stability to the lift arm assembly (230). A pair of actuators (238), which are hydraulic cylinders configured on the loader (200) to receive pressurized fluid from the power system (220), are pivotally coupled to both the frame (210) and the lift arm (234) at pivotable joints (238A and 238B) on each side of the loader (200), respectively. The actuators (238) are often referred to individually and collectively as lift cylinders. The operation (i.e., extension and retraction) of the actuators (238) causes the lift arm assembly (230) to rise and fall along a fixed path indicated by the arrow (237) by pivoting around the joint (216). Each of the pair of control links (217) is pivotally mounted on both sides of the frame (210) and one lift arm (232). The control links (217) help define the fixed lift path of the lift arm assembly (230).

[0046] Some lift arms, most prominent in excavators and also possible in other loaders, may have a controllable portion that pivots to another segment instead of moving together (i.e., along a predetermined path), as in the case of the lift arm assembly (230) shown in FIG. 2. Some power machines have a lift arm assembly having a single lift arm, as is known in excavators or some loaders and other power machines. Other power machines may have multiple lift arm assemblies, each independent of the others.

[0047] A tool interface (270) is provided adjacent to the second end (232B) of the lift arm assembly (230). The tool interface (270) includes a tool carrier (272) capable of receiving and securing various different tools on the lift arm (234). These tools have a complementary mechanical interface configured to be connected to the tool carrier (272). The tool carrier (272) is pivotally mounted on the second end (232B) of the arm (234). A tool carrier actuator (235) is operably coupled to the lift arm assembly (230) and the tool carrier (272) and is operable to rotate the tool carrier (272) relative to the lift arm assembly. The tool carrier actuator (235) is illustrated as a hydraulic cylinder and is often known as a tilt cylinder.

[0048] By having a tool carrier that can be attached to multiple different tools, changing from one tool to another can be done relatively easily. For example, a machine having a tool carrier can provide an actuator between the tool carrier and the lift arm assembly, and the removal or attachment of the tool does not require the removal or attachment of the actuator from the tool, or the removal or attachment of the tool from the lift arm assembly. The tool carrier (272) provides a mounting structure for a lift arm assembly that does not require a tool carrier, which easily attaches the tool to the lift arm (or other part of the power machine).

[0049] Some power machines may have tool-like devices that are pinned to a lift arm equipped with a tool or tilt actuator and directly coupled to the tool or tool-shaped structure. A common example of such a tool rotatably pinned to the lift arm is a bucket, and one or more tilt cylinders are attached to a bracket that is fixed directly to the bucket by welding or a clamping device. Such power machines do not have a tool carrier, but rather have a direct connection between the lift arm and the tool.

[0050] The tool interface (270) also includes a tool power source (274) available for connection to the tool of the lift arm assembly (230). The tool power source (274) includes a pressurized hydraulic fluid port to which the tool can be removedly coupled. The pressurized hydraulic fluid port optionally provides pressurized hydraulic fluid to provide power to one or more functions or actuators on the tool. The tool power source may also include a power source to provide power to an electric actuator and / or an electronic controller on the tool. The tool power source (274) also includes electrical conduits that communicate with a data bus on the loader (200) to enable communication between the controller of the tool and the electronic device of the loader (200).

[0051] In FIGS. 2 and 3, the frame (210) supports and surrounds the power system (220), so that the various components of the power system (220) are not visible. FIG. 4 includes a diagram of the various components of the power system (220). The power system (220) includes one or more power sources (222) capable of generating and / or storing power used in various machine functions. In a power machine (200), the power system (220) includes an internal combustion engine. Other power machines may include an electric generator, a rechargeable battery, various other power sources, or a combination of power sources capable of providing power to a given power machine component. The power system (220) also includes a power conversion system (224) operably coupled to the power source (222). The power conversion system (224) is, in turn, coupled to one or more actuators (226) that perform the functions of the power machine. The power conversion system (224) of various power machines may include various components, such as a mechanical transmission, a hydraulic system, etc. The power conversion system (224) of the power machine (200) includes a pair of optionally controllable hydrostatic drive pumps (224A; 224B) to provide a power signal to a drive motor (226A; 226B). The drive motors (226A; 226B) are operably coupled to axles in turn, and the drive motor (226A) is coupled to axle (228A; 228B) and the drive motor (226B) is coupled to axle (228C; 228D). The axles (228A-D) are coupled in turn to traction elements (219A-D). The drive pumps (224A; 224B) are mechanically, hydraulically, and / or electrically coupled to an operator input device to receive an operating signal that controls the drive pumps.

[0052] The arrangement of the drive pump, motor, and axle of the power machine (200) is one example of the arrangement of these components. As described above, the power machine (200) is a skid-steer loader, and the traction elements on each side of the power machine are controlled together through the output of a single hydraulic pump, a single drive motor of the power machine (200), or any one of the individual drive motors. Various other configurations and combinations of hydraulic drive pumps may be preferably used.

[0053] The power conversion system (224) of the power machine (200) also includes a hydraulic tool pump (224C) operably coupled to the power source (222). The hydraulic tool pump (224C) is operably coupled to a work actuator circuit (238C). The work actuator circuit (238C) controls the operation, including the lift cylinder (238) and the tilt cylinder (235), as well as the control logic. The control logic selectively permits the operation of the lift cylinder and / or the tilt cylinder in response to operator input. In some machines, the work actuator circuit (238C) also includes control logic that selectively provides pressurized hydraulic fluid to the attached tool. The control logic of the power machine (200) includes an open-center, series-arranged 3-spool valve. The spools are arranged to give priority to the lift cylinder, then the tilt cylinder, and then the pressurized fluid to the attached tool.

[0054] The above description of the power machine (100) and the loader (200) is provided for urban purposes and provides an urban environment in which the concept of the present invention described below can be realized. The embodiments disclosed in the present invention can be realized in power machines generally described by loaders such as the power machine (100) shown in the block diagram of FIG. 1, more specifically, a track loader (200), and unless specifically stated otherwise, the concept of the present invention described below is not limited to the environment specifically described above.

[0055] FIG. 5 illustrates aspects of a control system (280) that may be used to control specific functions of a power machine including the power machine (200) of FIG. 2 and FIG. 3. The control system (280) includes a controller (282), which may be composed of a general-purpose or special-purpose electronic processing unit that communicates, for example, with a memory (284). In some examples, the control system (280) may include one or more controllers. For example, some power machines may include dedicated controllers for engine control, drive control, driver input, display, radio / entertainment, and hub operation, having appropriate communication channels (e.g., a bus that may be physical or wireless) extending between controllers and between controllers and other components (e.g., sensors, wireless communication modules, etc.). In some examples, multiple controllers may be combined into modules within a common control unit (e.g., different software or hardware modules for a single controller). In this regard, one or more controllers may be considered to be composed of dedicated controllers or integrated into a larger control unit.

[0056] To allow the transmission of driver input commands, one or more input devices, generally referred to as input device(s) (286), communicate with the controller (282). The driver may operate the input device(s) (286) to provide user input signals to the controller (282), including following generally well-known input and data transmission protocols. In some examples, one or more of the input devices (286) may be configured as input / output combining devices according to various known configurations.

[0057] In some examples, the input device(s) (286) may include a user input interface (287). For example, the user input interface (287) may be composed of a display device capable of receiving input from a user through one or more input devices, such as the display itself (e.g., a touchscreen display device) or buttons, switches and / or a keypad, or other suitable devices associated with the display and capable of providing information to the user based on signals received from the controller (282) or other sources. The user input interface (287) may also be a series of input devices as described above that can be operated by a driver without a corresponding display.

[0058] In some examples, multiple input devices may be configured to provide commands, receive signals, or control the operation of the power machine. In the illustrated example, the controller (282) also communicates with an input device configured as a starting mechanism (288), as well as a power conversion system (224) (see FIG. 4), an actuator (226) (see FIG. 4), and a work actuator circuit (238C) (see FIG. 4). Thus, the controller (282) may receive input from the starting mechanism (288) that prompts the commanded starting of the power source (222) (e.g., internal combustion engine), as well as other inputs that selectively operate devices of the power conversion system (224), the actuator (226), the auxiliary system (289) (e.g., HVAC system, radio, etc.), or the work actuator circuit (238C). Accordingly, various power machine functions are controlled.

[0059] According to one example, the starting mechanism (288) may be composed of an ignition switch (or power source switch) comprising a switch operated by a physical key, button, toggle, etc. In some cases, the starting mechanism (288) may be integrated with another of the input device(s) (286), including a user input interface (287). In some cases, activation of the starting mechanism (288) may generally trigger a starting operation as well as the starting of the power source (e.g., may trigger an initialization operation for the user input interface (287) or another subsystem of the control system (280)).

[0060] In general, various other configurations are possible, including a configuration in which the control system communicates with additional power machines or other functional subsystems. Accordingly, the principles of access and operation control discussed herein can be easily applied in relation to various other power machine functions or power machine subsystems. Additionally, although the controller (282) is schematically illustrated as a single component, other configurations may include multiple controllers that can be distributed to the power machines or elsewhere, as mentioned above.

[0061] Through the appropriate configuration of the control system (280) or other similar control system, the power machine may be configured so that specific power machine functions (e.g., full, partial, or zero functions) are available during the startup process. Additionally, if authorization for the operator is appropriately verified, additional power machine functions may be available, including a wireless connection between the mobile device and the power machine to identify the presence of an authorized user and related priorities or restrictions, where appropriate.

[0062] For example, the controller (282) may be configured to realize a temporary start mode during the start process of the power machine, and limited power machine functions are selectively activated in one or more of the power source (222) (e.g., via control of the start mechanism (288)), hydraulic work group system (e.g., via the work actuator circuit (238C) of FIG. 4), power conversion system (224), actuator (226), auxiliary system (289), or other related power machine systems. Correspondingly, certain other power machine functions may not be activated by the controller (282) while the power machine (200) is in the start mode (e.g., may be locked).

[0063] While continuing to operate within startup mode, the control system (280) may also use a known wireless communication protocol to identify potential wireless connections with one or more mobile devices, preferably to establish a wireless connection with the device(s). For example, the availability of a specific mobile device may be identified using Bluetooth or other short-range communication protocols, and a connection may be established accordingly to allow for the wireless exchange of information (e.g., IMEI or other identifiers of the mobile device). Alternatively, the mobile device may use a known wireless communication protocol to identify the control system (280) and establish wireless access with the control system. However, only a mobile device that has previously been connected to the control system (280) (e.g., by a pairing operation via a Bluetooth protocol) may establish a wireless connection with the control system.

[0064] Once a mobile device is identified, the control system (280) can determine whether and how to use power machine functions based on the identification of the mobile device. For example, if a wireless connection indicates that the mobile device is associated with a driving profile that includes specific permissions and operating priorities, the control system (280) may allow the operation of the power machine according to such permissions and priorities. In contrast, if a wireless connection is not established with the mobile device or is established with a mobile device that is not associated with a driving profile, the control system (280) may continue to allow limited (e.g., none) power machine functions accordingly (e.g., according to a predetermined permission of the starting mode).

[0065] In this regard, referring to FIGS. 6 and FIGS. 5, an exemplary starting process method (300) for accessing the function of a power machine (200) that can generally be executed by a controller (282) and a control system (280) ( FIG. 5). In particular, the power machine (200) is referenced, but the method disclosed in the present invention, including that shown in FIG. 6, can generally be implemented in various other power machines.

[0066] According to the illustrated example, the method (300) may be initiated by placing the power machine (200) in the block (302) into a start mode. For example, the control system (280) may initialize the user input interface (287) (see FIG. 5) or provide input to another device operably connected to the power source (e.g., battery) of the power machine (200). In some examples, the operator may trigger the execution of the method (300) by manually operating the start mechanism (288) (e.g., to the operating position) to activate the power source (e.g., start the engine). Correspondingly, under the operation of the start mechanism (288), power may be applied to one or more computing devices on the power machine (200), including the user input interface (287), to allow access to limited power machine functions in the block (304) in accordance with the permission of the start mode.

[0067] As generally mentioned above, during a start mode defining limited power machine functions, the operator of the power machine (200) may be allowed to activate the engine or other primary power source, or may be allowed to operate by being driven only by an auxiliary power source (e.g., a small battery). They may not be able to command the operation of specific actuators (e.g., work group actuators) or perform specific operations (e.g., moving a lift arm, increasing engine speed above idle, or moving at a speed faster than a critical ground speed). However, according to other examples, limited power machine functions may include zero access to power machine functions. In this regard, for example, a specific computer system may be initialized, but power machine operations may not be available for actual control even if the primary power source (e.g., engine) is started. In some cases, the power machine may not have an engine but may have a power source such as a battery pack. In such machines, the battery power source management system may prohibit power transmission to the actuators until communication with a mobile device is established.

[0068] In some cases, the power source may be turned on during the start mode so that the user input interface (287) allows the operator to operate the user input interface (287) to control specific functions of the power machine (200), such as one or more devices of the auxiliary system (289). According to some examples, the limited functions of the power machine (200) during the start mode may correspond to limited access for the operation of one or more work elements, such as the work actuator circuit (238C), the auxiliary hydraulic system (291), the power conversion system (224), and various traction elements.

[0069] Generally, the operation of the power machine in the start mode may correspond to the operation of the power machine started from a non-powered state (e.g., a state where the engine is not running). However, in some cases, the power machine may be placed differently in the start mode (block (302)). For example, the power machine may operate in the start mode (e.g., limited power machine function) due to an intermediate operator operation or other event (e.g., locking of a touchscreen or other input device) after the engine has already started.

[0070] Furthermore, the controller (282) may also be configured to establish a wireless connection to the mobile device (290) in block (306) (e.g., via Bluetooth or Wi-Fi communication). According to some examples, the controller (282) may automatically start searching for a wireless connection to the mobile device (290) upon receiving power (e.g., after the power machine in block (302) is placed in start mode), but other sequences are also possible that include a sequence in which one or more wireless connections may be established before the start mode is initiated. According to other examples, the mobile device may detect the presence of the controller (282) and establish a connection to the controller (in block (306)).

[0071] Using the established wireless connection with the mobile device (290) from the block (306), the controller (282) can then identify which operating profile(s) are associated with the mobile device (290). In some cases, once the connection is established in the block (306), the controller (282) can identify whether the mobile device (290) is associated with one or more operating profiles (310) for the power machine (200). For example, the power machine (200) may store one or more operating profiles corresponding to one or more operating modes of the power machine (200) that correspond to one or more operating environments (e.g., in memory (284)). Thus, based on the association between the mobile device and one or more operating profiles and the established connection with the mobile device (e.g., from the operation of the block (306)), the controller (282) may provide the opportunity to select from at least two operating profiles to relatedly determine which power machine function is authorized for a specific operating environment. If only one driving profile is available, the driver does not need to select a driving profile, and it is selected automatically.

[0072] Accordingly, for example, in the case of a power machine currently operating with limited power machine functions, when the controller (282) establishes a connection with a mobile device (290) connected in block (306) and a corresponding driving profile for the power machine (200) is selected, the controller (282) may occasionally allow access to additional power machine functions corresponding to the permission or setting of the driving profile selected in block (308). According to some examples, the additional power machine functions allowed from the operation in block (308) may include the operation of the traction element of the power machine (200) or the operation of the work element. For example, the user may not be allowed to drive the power machine (200) or operate the lift arm or the tool of the power machine during the start mode, but once the connection with the relevant mobile device is established in block (306), the execution of the corresponding function may be allowed based on the permission of the associated driving profile. According to some examples, for a specific operator, the additional power machine functions allowed in block (308) may include full power machine functions without access restrictions.

[0073] As discussed above, the power machine (200) may store multiple driving profiles, and each driving profile may include one or more operating priorities, one or more operating permissions (e.g., a list or qualification for allowed or blocked functions), or one or more other settings, some of which may or may not be unique to a specific driver. In this regard, for example, a driving profile may include settings regarding priorities for auxiliary system (289) functions, power conversion system (224), auxiliary hydraulic system (291), or work actuator circuit (238C). In some cases, operating restrictions for these systems may be set within the driving profile, including vehicle speed limits, work element operating speed limits, geographical restrictions, etc. Thus, according to one example, a driving profile for a driver with a certain level of experience may include permissions appropriate to that level of experience, which may include partial or total restrictions on the operation of specific work elements.

[0074] In some cases, the operation profile can be established by the operator through interaction with the user input interface (287) (see FIG. 5). According to another example, the operation profile can be established when the power machine is manufactured by loading a predefined operation profile into the controller (282) before or during the power machine manufacturing process.

[0075] Now, referring to FIGS. 5 and FIGS. 7-10, various exemplary user interfaces for a user input interface device (287) are illustrated. FIG. 7 illustrates a user interface (400) for displaying the current mobile device status (402) based on an established connection with a first mobile phone (290) associated with a corresponding driving profile. Additionally, the user interface (400) also displays potential connections (404) with mobile devices (290, 290') within the detection range of the controller (282). Thus, for example, the driver may be provided with the option to connect (or disconnect) with a desired mobile device (290, 290') from the list of potential connections (404). Alternatively (or additionally), as described above, the controller (282) may sometimes determine the order of connections based on proximity, signal strength, or a predetermined priority list.

[0076] FIG. 8 illustrates an exemplary user interface (400') for creating an association (406) between a mobile device (290) within the detection range of a controller (282) and a driving profile (410) of a power machine (200). While various approaches are possible, the user interface (400') can provide a relatively simple process for associating a mobile device with a driving profile (410). For example, after the operator indicates appropriate authorization to use the power machine (200) (e.g., via another mobile device, manual input, etc.) and identifies the driving profile (410) as being associated with the operator (e.g., via a previous login by the operator), the user interface (400') can automatically (or upon request) provide an option to associate the driving profile (410) with a connected (or available) mobile device. Therefore, for example, if the mobile device (290) is already connected to the power machine, the operator can connect the mobile device (290) to the driving profile (410) relatively easily, including simply selecting a "key generation" (or similar) icon or button.

[0077] According to some examples, in order to create an association with a mobile device (290), it may be necessary that the relevant driving profile is not yet associated with the mobile device. According to some examples, in order to create an association with a mobile device (290), it may be required that the mobile device (290) has not previously been associated with another driving profile. According to some examples, only a selected driver (e.g., an administrator) may be allowed to associate a specific mobile device with a specific driving profile.

[0078] In some cases, the removal of the connection between the mobile device and the driving profile may proceed similarly, but may also proceed in reverse. For example, FIG. 9 illustrates an exemplary user interface (400') for removing the association (408) between the mobile device (290) and the driving profile (410) of the power machine (200). Thus, for example, the driver may remove the connection between the mobile device (290) and the driving profile relatively easily, including simply selecting a "key delete" (or similar) icon or button. According to some examples, the association between the mobile device (290) and the driving profile (410) may be removed regardless of whether the mobile device (290) is currently wirelessly connected to the power machine (200). According to some examples, only a selected driver (e.g., an administrator) may be allowed to remove the association between a specific driving profile and a specific mobile device.

[0079] In some cases, the connection with a specific driving profile can be easily switched between different mobile devices. For example, FIG. 10 illustrates an exemplary user interface (400"') for switching the association (412) between a mobile device (290) and a driving profile (410) of a power machine (200) to an association between another mobile device (290') and a driving profile (410). Thus, for example, the operator may switch the connection between the mobile device and the driving profile relatively easily, including simply selecting a "key replacement" (or similar) icon or button. For example, this may be useful when the operator wants to change mobile devices or want to connect one of multiple mobile devices to a driving profile.
