Abstract

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

Description

Access control to power machine functions

The present invention relates to power machinery. More specifically, the present invention relates to activating or deactivating power machine functions during the start-up process of the power machine.

Power machinery for the purposes of this invention includes any type of machine that generates power for the purpose of accomplishing a specific task or variety of tasks. One type of power machine is a work vehicle. Work vehicles are typically self-propelled vehicles that have work devices such as lift arms (some work vehicles may have other work devices) that can be manipulated to perform work functions. Work vehicles include loaders, excavators, utility vehicles, tractors including small tractors, and trenchers, to name a few. Other types of power machinery may include mini loaders (e.g. mini track loaders) and mowers.

The above description merely provides general background information of the invention and is not intended to be an aid in determining the scope of the claimed invention.

The present invention relates to activating or deactivating power machine functions during the start-up process of the power machine.

Examples of the subject matter disclosed herein may use a wireless connection between a mobile device and a power machine to provide access to certain power machine functions. In some examples, this allows the driver to perform certain operations under a limited functionality mode until a connection is established between the power machine and the authorized driver's mobile device. The mobile device may sometimes be associated with a corresponding driving profile, and the power machine can perform operations based on that driving profile (e.g., switch to a full function mode to allow full operation of all power machine functions).

According to some aspects of the 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 operation of the power source of the power machine based on receiving a signal from an input device (eg, due to manual actuation). After receiving a signal from the input device, the control device may restrict operation of one or more power machine functions of the power machine until a wireless connection is established between the controller and the mobile device corresponding to the operating profile of the power machine.

In some examples, the 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., work group element).

According to some aspects of the invention, a method of 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 powered machine, the powered machine may be placed in a start-up mode. Based on the starting mode configuration of the power machine, limited access to power machine functions may be provided depending on the permissions of the starting mode. The method includes discovering one or more mobile devices through a controller in communication with a 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 driving profile of the power machine, and the mobile device. Based on the step of identifying an association between the device and the driving profile, the method further includes allowing access to additional power machine functions corresponding to the driving profile.

In some examples, authorization of a starting mode may include operation of the power source of the power machine, but may not include operation of one or more work elements (e.g., traction or work group elements) of the power machine. In some examples, the additional power machine functions to which access is permitted are distinct from the operation of the power machine's power source and may include one or more of the operation of a traction element or the operation of a work element (e.g., work group element). In some examples, additional power machine functions may include full power machine functions. In some examples, a mobile device may include one of a cell phone, tablet, laptop, or personal digital assistant.

According to some aspects of the invention, a power machine is provided. The power machine includes a power source, an operator station, and a user input interface within the operator station including an input device configured to receive input for activation of the power source by an operator within the operator 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 a power source, and a control system. The control system may be configured to activate the power source based on a signal from an input device. After activating the power source, the control system can be further configured as follows. Initially providing limited access to power machine functions; Establish a wireless connection with a mobile device corresponding to the driving profile; and initially providing limited access to power machine functions based on the wireless connection setup and then providing access to one or more additional power machine functions based on the driving profile.

In some examples, the control system identifies potential wireless connections with a plurality of mobile devices, including a mobile device, prior to establishing a wireless connection with the mobile device; and configured to prioritize 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 can include a display configured to receive an activation code. The control system may be configured to bypass receipt of an activation code via the display based on establishing a wireless connection with the mobile device.

The Summary and Abstract of the Invention are provided to explain the 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 technology described in the claims and is not intended to be used as an aid in determining the scope of the subject matter claimed in the present invention.

Some examples of the disclosed techniques include improved start-up procedures for powered machines, improved access management to specific powered machine functions, or improvements to powered machine systems based on driver preferences or other driving profile information (e.g., function permissions). Can provide automated (e.g., automated) configuration. For example, in some embodiments, the control device may be configured to establish a wireless connection with a mobile device to determine appropriate permissions to responsively enable selection of relevant power machine functions (i.e., allow access and control). It can be configured. Thus, for example, a power machine could automatically allow an authorized user to operate certain (e.g., all) power machines, without the operator having to use a mechanical key or manually engage the control system to identify and demonstrate proper authorization. , power machines can be configured to execute these tasks according to appropriate operational priorities (e.g., tailored responses to control inputs). Therefore, some examples can help prevent unauthorized access to power machine functions while streamlining access and general start-up procedures for authorized users.

The concepts disclosed herein are explained and illustrated with reference to examples. However, these concepts are not limited to application to the configuration details and arrangement of components of the illustrated embodiment and may be implemented or implemented in various other ways. The terminology herein is used for the purpose of describing the invention and should not be considered limiting. As used herein, words such as "including," "comprising," and "having" and their variations are meant to include the listed items, their equivalents, as well as additional items. .

As used herein, the phrase "initialization process" or "computer initialization process" means that when a computerized device is powered on, the device operates normally (e.g., running a BIOS or other startup procedure, using a touchscreen or other input device). It refers to the work of preparing for activation. Likewise, “start-up process” means the operation of a power machine starting from an unpowered condition to prepare the power machine for powered operation (e.g., traction and work operations).

In addition, the "power machine function" as used in the present invention generally refers to the operation of a power source (e.g., an engine or battery), a power conversion system that converts the output from the power source into a form usable by the work element, and a work element (e.g., Refers to the movement and power-based operation of power machinery, such as the operation of work elements such as traction elements and other actuators that can move lift arms or other devices. “Power machine functions” specifically include the operation of display screens or other input/output devices for control systems, the operation of computer-based security systems (e.g. locking systems) and the general operation of other electronic control devices (e.g. hub controllers, etc.). It can be distinguished from what it refers to as “operating system functions.” However, certain power machine functions may necessarily include or rely on operating system functionality, including electronic control of hydraulic equipment, user input interfaces (e.g., displays), sensors, switches, actuators, and signaling devices.

Additionally, as used herein, operation of a power machine with “limited” power machine functions means operation of a power machine that accesses only a subset of the possible power machine functions. In contrast, the operation of a power machine with “full” power machine functions represents the operation of a power machine with unrestricted use of power for all power machine functions (i.e., normal power machine operation). In general, operations with restricted power machine functions may include fully restricted operations (i.e., no power machine functions are permitted) or partially restricted operations (i.e., some functions are permitted, such as the non-limiting examples below). .

In some cases, limited power machine functions may include operating systems for non-task functions only, including operating input devices (e.g., joysticks, push buttons, or touchscreen displays), radios, climate control systems, etc. In some cases, a power machine may be provided with limited power machine functions even if the power source (e.g., the engine of the power machine) is operating. For example, a power source may be activated, but a user permitted to access limited power machine functions cannot cause power to be transmitted by the power source for operation of work elements or traction elements.

Additionally, as used herein, the phrase "mobile device" refers to a mobile phone (e.g., feature phone or smartphone), tablet, laptop, personal digital assistant, or device configured for wireless communication and that can be individually electronically identified through the wireless communication. refers to other mobile devices capable of communicating via Wi-Fi (e.g., 2.4 GHz, 4G, 5G, etc.) and Bluetooth protocols (Bluetooth is a registered trademark of Bluetooth SIG, Inc. in the United States or other jurisdictions).

Additionally, the phrase "physical key" as used herein refers to a traditional key or key fob, generally made of metal, plastic, or a combination thereof, that can be used to access the operator's area of a power machine or to start the machine. there is. In this regard, a “mechanical” physical key may be configured to mechanically engage the lock of another component, such as a key switch on a power machine door or user input panel.

Additionally, as used herein, “driving profile” means a stored record representing one or more permissions, preferences or other attributes related to operating functions. For example, some driving profiles have settings that represent different power functions (e.g., those related to traction systems, specific work group actuators, geographic boundaries, etc.), settings that define the work preferences of a particular driver (e.g., cab/comfort settings, (related to the response characteristics of a particular actuator, etc.), or settings that characterize the response or permission to operate a power machine.

In conventional designs, powered machines have power from a power source (e.g., the ability to start or operate an engine), actuators for traction operations (e.g., for terrain mobility), and work group actuators for task operations (e.g., for non-mobility activities). It may be equipped to provide controls for controlling a variety of functions, including access to and control of (hydraulic actuator operation), convenience and other operating settings (e.g., climate control), etc. Accordingly, a power machine typically includes a variety of control devices to control various functions, including one or more operator interfaces configured to receive operator input.

Some examples of the disclosed techniques include improved start-up procedures for powered machines, improved access management to specific powered machine functions, or improvements to powered machine systems based on driver preferences or other driving profile information (e.g., function permissions). Can provide automated (e.g., automated) configuration. For example, in some embodiments, the control device may be configured to establish a wireless connection with a mobile device to determine appropriate permissions to responsively enable selection of relevant power machine functions (i.e., allow access and control). It can be configured. Thus, for example, a power machine could automatically allow an authorized user to operate certain (e.g., all) power machines, without the operator having to use a mechanical key or manually engage the control system to identify and demonstrate proper authorization. , power machines can be configured to execute these tasks according to appropriate operational priorities (e.g., tailored responses to control inputs). Therefore, some examples can help prevent unauthorized access to power machine functions while streamlining access and general start-up procedures for authorized users.

In some examples, limited powertrain functionality may be provided during a start-up process before the mobile device is used to authorize specific powertrain operations. For example, the driver may initiate an initialization process for the power machine's control system (e.g., turn on the touchscreen), or initiate a start-up process for the power machine's power source (e.g., press the "Turn on engine" button). (you can press ). In some cases, certain initialization (or start-up) operations may be performed accordingly, but full functionality and operation of the power machine may not be initially permitted. That is, the operator may be permitted to access only limited power machine functions during the power machine's starting mode.

As part of the start-up operation or at other times, the control system may search for and establish a wireless connection with one or more mobile devices and may allow access to additional powertrain functions based on the established connection. For example, after the driver starts the engine or an input interface (e.g. a touchscreen), communication may be established via a wireless connection between the control system and the driver's mobile device previously connected to the control system of the power machine. (e.g. paired with a control system using the Bluetooth protocol). Once a mobile device is paired with a control system, the operator pairing the mobile device will set up a list of working profiles that can be used on the power machine when the power machine is connected to a particular mobile device in the future, for example by excluding some of the available driving profiles. You can. The driving profiles available for the corresponding mobile device are tracked in the control system of the power machine. In some examples, a previously associated mobile device detects and establishes communication with the control system. In some examples, the control system detects and establishes communication with a 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 operating profiles selected in the control system. For example, once a connection between a mobile device and a driving profile is established, the control system may allow additional powertrain functions (e.g., full powertrain functions) for the user based on the driving profile. The working profile may be a default driving profile, or once communication is established, the driver may select from a plurality of driving profiles available to the driver by selecting one from a list provided to the driver. However, during start-up operation and before the connection between the mobile device and the driving profile is established, the control system may allow the user limited powertrain functions (e.g., no functions are allowed, functions involving only engine operation, engine and functions that include the operation of HVAC equipment, etc.). Likewise, if the connected mobile device is not associated with a driving profile that has authorized access (or is not associated with a driving profile at all), the control system may provide restricted access, at least until appropriate authorization for the driver is available or can be verified. Only power machine functions can continue to be provided. In some instances, if the operator takes additional steps, such as manually entering a passcode on the display or using a physical key, the operator may be able to access the control system from the power machine even if a wireless connection is not established between the control system and the mobile device. Full functionality can be activated.

In some cases (as noted above), a computerized device on a power machine may automatically begin searching for and establishing a wireless connection with a mobile device during a start-up mode (e.g., during a start-up process prior to authorization verification). For example, an initialization input from the driver (e.g., “start the engine” input) could cause the control system to automatically search for nearby mobile devices and attempt to establish a wireless connection accordingly. Thus, for example, in some cases the starting operation may proceed relatively smoothly with minimal manual input from the driver. Additionally, as noted generally above, certain power machine functions may be available to the operator even before wireless authentication is complete. In some other cases, as mentioned above, when the power machine is powered in a starting mode, the computerized device of the power machine can be located by a mobile device.

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

These concepts can be implemented in a variety of power machines as described below. A representative power machine capable of realizing the embodiments is shown in diagram form in Figure 1, and one example of such a power machine is shown in Figures 2 and 3 and is described below before inventing the embodiments. In order to simplify the description of the present invention, only one power machine is shown and described as a representative power machine. However, as mentioned above, the following examples can be implemented on any of a number of power machines, including power machines of different types than the representative power machines shown in FIGS. 2 and 3. For the purposes of the present invention, a power machine includes a frame, at least one work element and a power source capable of providing power to the work element to perform a task. One type of power machine is a self-propelled work vehicle. A self-propelled work vehicle is a type of power machine and includes a frame, work elements, and a power source capable of powering the work elements. At least one working element is a motive system that moves the power machine under power.

1 represents a block diagram illustrating the basic system of a power machine 100 into which the embodiments described below may advantageously be 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 described above, at the most basic level, a power machine for the purposes of the present invention includes a frame, a power source and work elements. The power machine 100 has a frame 110, a power source 120, and a work element 130. Since the power machine 100 shown in Figure 1 is a self-propelled work vehicle, it also has a working element of the power machine and a traction element 140, which is itself a working element, provided to move the power machine over the support surface. It has an operator station 150 that provides a controlled driving position. A control system 160 is provided to interact with other systems to perform various tasks, at least in part, in response to control signals provided by the driver.

Specific work vehicles have work elements that can perform dedicated tasks. For example, some work vehicles have lift arms to which tools such as buckets are attached by a pinning arrangement. The work element, or lift arm, can be manipulated to position the tool to perform a task. In some cases, to position the tool, the tool may be positioned relative to the work element such that the bucket is rotated relative to the lift arm. Buckets are attached and used under normal operation of these work vehicles. These work vehicles can accommodate other tools in place of the original bucket by disassembling the tool/work element combination and reassembling the other tools. Other work vehicles are intended to be used with a wide variety of tools and have tool interfaces such as tool interface 170 shown in FIG. 1 . Most fundamentally, the tool interface 170 is a connection device between the frame 110 or work element 130 and the tool, which is as simple as a connection point that directly attaches the tool to the frame 110 or work element 130. or may be more complex and are described below.

In some power machines, tool interface 170 may include a tool carrier, which is a physical assembly that is movably attached to a work element. The tool carrier has engagement features and locking features for receiving and securing a number of different tools to the work element. One characteristic of these tool carriers is that once the tool is attached to the carrier, the carrier is fixed 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. do. As the term is used herein, tool carrier is not simply a pivotable connection point, but a special purpose-built device intended to accommodate and secure a variety of tools. The tool carrier itself can be mounted on a work element 130, such as a lift arm or frame 110. Tool interface 170 may also include one or more power sources to power one or more work elements of the tool. Some power machines may have multiple work elements with tool interfaces, each of which may have a tool carrier to accommodate a tool, although this is not required. Some other power machines may have a single work element with multiple tool interfaces, and a single work element can accommodate multiple tools simultaneously. Each of these tool interfaces has one tool carrier, although this is not required.

Frame 110 includes a physical assembly capable of supporting various other components attached to or positioned thereon. Frame 110 may include several individual components. Some power machines have rigid (rigid) frames. That is, no part of the frame is movable relative to any other part of the frame. Other power machines have at least one part that can move relative to other parts of the frame. For example, an excavator may have an upper frame portion that rotates relative to a lower frame portion. Other work vehicles have articulated frames in which portions of the frame pivot relative to other portions to achieve a steering function.

Frame 110 is configured to provide power for use by tools attached via tool interface 170 in some examples, as well as to provide power to one or more work elements 130, including one or more traction elements 140. Supports the configured power source 120. Power from power source 120 may be provided directly to any of work element 130, traction element 140, and tool interface 170. Alternatively, power from power source 120 may be provided to control system 160, which in turn selectively provides power to components that may use the power to perform work functions. Power sources for power machines include engines such as internal combustion engines and power conversion systems such as mechanical transmissions or hydraulic systems that can convert rotational output from the engine into a form of power usable by work elements. Other types of power sources may be incorporated into power machines, including combinations of power sources commonly known as power sources or hybrid power sources.

1 shows a single work element, designated work element 130, but various power machines may have any number of work elements. Work elements are usually attached to the frame of a power machine and can move relative to the frame when performing work. Traction elements 140 are also a special case of working elements in that their working function generally moves the power machine 100 over a support surface. The traction element 140 is shown and shown separately from the work element 130 because many power machines have additional work elements other than the traction element, although this may not always be the case. The power machine may have any number of traction elements, any or all of which may receive power from the power source 120 to propel the power machine 100. Traction elements may be, for example, track assemblies, wheels attached to axles, etc. The traction element may be mounted on the frame such that movement of the traction element is limited to rotation about the axles (steering is achieved by skidding), or alternatively, the traction element may pivot relative to the frame to achieve steering. It can be pivotably mounted on the frame.

Power machine 100 includes an operator station 150 that includes an operating position from which an operator can control the operation of the power machine. In some power machines, operator station 150 is defined by an enclosed or partially enclosed operator station. Some power machines in which embodiments of the present invention may be implemented may not have an operator station or operating area of the type described above. For example, a walk behind loader may not have an operator station or operating area, but rather an operating position that functions as an operator station to properly operate a power machine. More broadly, power machinery other than work vehicles may have operating stations that are not necessarily similar to the operating positions and operating areas noted above. Additionally, some power machines, such as power machine 100, and others, regardless of whether they have an operating area or operating position, may be operated remotely instead of or in addition to an operating station on or adjacent to the power machine (i.e., remotely. can be operated (from a located operator station). At least some of the operator control functions of the power machine may include an application that can be operated from an operating position associated with a tool connected to the power machine. Alternatively, for some power machines, a remote control may be provided that can control at least some of the operator control functions on the power machine (i.e., remote from the power machine and any tool coupled to the power machine).

Figures 2 and 3 show a loader 200, one specific example of the power machine shown in Figure 1, on which the embodiment described below may be advantageously used. The loader 200 is a skid-steer loader, which has traction elements (in this case, 4 wheels) mounted on the frame of the loader by a rigid axle. Here, “solid axle” refers to the fact that the skid-steer loader 200 does not have any traction elements that can be rotated or steered to achieve a turn of the loader. Instead, skid-steer loaders have a drive system that independently powers one or more traction elements on each side of the loader, providing different traction signals to each side, thereby tending to cause the machine to slide over a support surface. These varying signals provide power to the traction element(s) on one side of the loader to move the loader in the forward direction and power the traction element(s) on the other side to move the loader in the reverse direction. and pivoting the loader around a central radius within the footprint of the loader itself. The term "skid-steer" typically refers to a loader with slippery steering and wheels as traction elements, as described above. However, it should be noted that many track loaders also pivot by sliding, and are technically skid-steer loaders even though they do not have wheels. For the purposes of the present invention, unless otherwise stated, the term skid steer should not be limited to loaders having wheels as traction elements. Accordingly, although some of the exemplary power machines discussed herein are presented as skid-steer power machines, some examples disclosed herein may be implemented in a variety of other power machines. For example, some examples may be realized in small loaders or small excavators that do not perform rotation through skidding.

Loader 200 is one particular example of power machine 100 shown broadly in Figure 1 and described above. Accordingly, features of loader 200 described below use reference numerals similar to those used in FIG. 1 . For example, loader 200 is described as having a frame 210 just as power machine 100 has a frame 110 . The skid-steer loader 200 described herein is intended to provide a reference to an environment in which the embodiments described below regarding track assemblies and mounting elements for mounting the track assemblies to a power machine may be practiced. The loader 200 is not essential to the embodiments disclosed herein, and thus the embodiments described below are specifically limited in the description of the features described as may or may not be included in a power machine other than the loader 200 in which the embodiments can be realized. should not be considered Unless specifically stated, the embodiments described below can be practiced on a variety of power machines, and loader 200 is just one of such power machines. For example, some or all of the invention described below may be implemented in many different types of work vehicles, including various other loaders, excavators, trenchers and dozers, to name a few.

The loader 200 includes a frame 210 that supports a power system 220 that can generate or provide power to operate various functions on the power machine. Power system 220 is shown in block diagram form but is located within frame 210. Frame 210 also has a lift arm assembly 230 that is powered by power system 220 to perform various tasks. Supports work elements. 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, is a tool carrier 272 that can accommodate and secure a variety of tools to the loader 200 for performing various tasks and a tool carrier 272 to selectively provide power to tools that can be connected to the loader. supports a tool interface 270 that includes a power coupler 274 to which it can be coupled. Power coupler 274 may provide a hydraulic source, a power source, or both. Loader 200 includes an operator station 250 that defines an operator station 255 where an operator can operate various controls 260 to cause the power machine to perform various work functions, including various work functions. . Operator station 250 can be pivoted backwards about an axis extending through mount 254, providing access to power system components when maintenance and repairs are required.

Operator station 255 includes a driver's seat 258 and a plurality of operator input devices including control levers 260 that can be operated by the operator to control various machine functions. 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 integrated into hand grips or display panels. It can be a program input device. Activation of the driver input device may generate signals in the form of electrical signals, hydraulic signals and/or mechanical signals. Signals generated in response to driver input devices are provided to various components of the power machine to control various functions of the power machine. Among the functions controlled by the operator input device of the power machine 100 include control of the traction element 219, the lift arm assembly 230, the tool carrier 272, and any other device that can be operably coupled to the tool. Provides signals to tools.

The loader is provided at the operator station 250 to provide a display of information related to the operation of the power machine in a form that can be perceived by the operator, for example, as an audible and/or visual indication. It may include a human-machine interface including a display device. Auditory indications may come in the form of buzzers, bells, etc., or verbal communication. Visual displays can appear in the form of graphs, lights, icons, gauges, alphabetical characters, etc. The display may be dynamic to provide dedicated indications, such as warning lights or gauges, or to provide programmable information, including programmable display devices such as monitors of various sizes and functions. The display device can provide diagnostic information, troubleshooting information, command information, and various types of information to assist the operator with the power machine or tools associated with the power machine. Other information that can be used by the driver can also be provided. Other powered machines, such as walk-behind loaders, may not have an operator station, operating area, or seating. The operating position of such a loader is generally defined as the most suitable position for the driver to operate the driver input device.

Various power machines incorporating or interacting with the inventive concepts described below may have a variety of different frame components supporting various work elements. The components of the frame 210 of the present invention are provided illustratively for purposes of the present invention, and the frame 210 is not the only form of frame for a power machine on which the concept of the present invention may be implemented. The frame 210 of the loader 200 includes an undercarriage or a lower part 211 of the frame and an upper part 212 of the main frame or frame supported by the undercarriage. In some embodiments, the main frame 212 of the loader 200 is attached to the chassis 211, such as by welding the chassis and the main frame or using fasteners. Alternatively, the main frame and chassis may be formed as one piece. The main frame 212 includes a pair of uprights 214A and 214B located on both sides toward the rear of the main frame, supporting the lift arm assembly 230 and to which the lift arm assembly 230 is pivotally attached. do. Lift arm assembly 230 is shown pinned to each of uprights 214A and 214B. For purposes of the present invention, a combination of mounting portions on uprights 214A; 214B, lift arm assembly 230, and mounting hardware (including pins for securing the lift arm assembly to the main frame 212) is assembled. They are collectively referred to as joints 216A and 216B (one located on each side of the upright portion 214). Joints 216A; 216B are arranged along axle 218 and allow the lift arm assembly to pivot about axle 218 relative to frame 210, as described below. Other power machines may not include uprights on both sides of the frame or may not have lift arm assemblies 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 at the front or rear ends of the power machine. Other machines may have multiple work elements including multiple lift arms, each of which is mounted on the machine with its own unique structure. Frame 210 also supports a pair of traction elements in the form of wheels 219A-D on either side of loader 200.

The lift arm assembly 230 shown in FIGS. 2 and 3 is 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 machinery, that can implement embodiments of the present invention. This is one example. The lift arm assembly 230 is known as a vertical lift arm, and the lift arm assembly 230 has a lift path 237 that forms a generally vertical path relative to the frame 210 under the control of the loader 200. means that it is movable (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 that is different from the radial path of lift arm assembly 230. For example, some lift paths on other loaders provide a radial lift path. Other lift arm assemblies may have expandable or telescoping portions. Other power machines may have multiple lift arm assemblies attached to their frames, each lift arm assembly being independent of the others. Unless specifically stated herein, the inventive concept disclosed in the detailed description is not limited to the type or number of lift arm assemblies to be coupled to a particular power machine.

Lift arm assembly 230 has a pair of lift arms 234 disposed on opposite sides of frame 210. For the lowered position shown in FIG. 2 , the first end of each lift arm 234 is pivotally coupled to the power machine at a joint 216 and the second end 232B of each lift arm is connected to the frame 210. It is located facing forward. Joint 216 is positioned toward the rear of loader 200 and lift arms extend along the sides of frame 210. Lift path 237 is defined by the path of movement of second end 232B of lift arm 234 as lift arm assembly 23 moves between its minimum and maximum heights.

Lift arms 234 each have a lift arm assembly ( It has a second portion 234B extending to the second end 232B of 230). The lift arms 234 are each coupled to a cross member 236 attached to the first portion 234A. Cross members 236 provide increased structural stability to 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 mounted on the frame (238) at pivotable joints 238A and 238B, respectively, on each side of the loader 200. It is pivotably coupled to both the 210) and the lift arm 234. Actuators 238 are often referred to individually and collectively as lift cylinders. Actuation (i.e., extension and retraction) of actuator 238 causes lift arm assembly 230 to pivot about joint 216 to raise and lower along a fixed path indicated by arrows 237. Each of the pair of control links 217 is pivotally mounted on the frame 210 and one lift arm 232 on both sides of the frame 210. Control link 217 helps define a fixed lift path for lift arm assembly 230.

Some lift arms, most prominent in excavators and possibly also in other loaders, are controllable to pivot about different segments instead of moving together (i.e., along a predetermined path), as in the case of lift arm assembly 230 shown in Figure 2. It can have parts. Some power machines have a lift arm assembly with a single lift arm, as known on excavators or some loaders and other power machines. Other power machines may have multiple lift arm assemblies, each independent of the others.

Tool interface 270 is provided adjacent second end 232B of lift arm assembly 230. Tool interface 270 includes a tool carrier 272 that can accommodate and secure a variety of different tools to lift arm 234 . This tool has a complementary machine interface configured to connect with tool carrier 272. Tool carrier 272 is pivotally mounted on second end 232B of arm 234. Tool carrier actuator 235 is operably coupled to lift arm assembly 230 and tool carrier 272 and operable to rotate tool carrier 272 relative to the lift arm assembly. Tool carrier actuator 235 is typically a hydraulic cylinder and is often known as a tilt cylinder.

By having a tool carrier that can be attached to a plurality of different tools, changes from one tool to another can be made relatively easily. For example, a machine having a tool carrier may provide an actuator between the tool carrier and the lift arm assembly, wherein removal or attachment of the tool involves removal or attachment of the actuator from the tool, or removal or attachment of the tool from the lift arm assembly. don't need it Tool carrier 272 provides a mounting structure for the lift arm assembly that easily attaches the tool to the lift arm (or other part of the power machine) without the need for a tool carrier.

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

Tool interface 270 also includes a tool power source 274 available for connection of a tool to lift arm assembly 230. Tool power source 274 includes a pressurized hydraulic oil port to which a tool can be removably coupled. The pressurized hydraulic oil port optionally provides pressurized hydraulic oil to power one or more functions or actuators on the tool. The tool power source may also include a power source to power electrical actuators and/or electronic controllers on the tool. Tool power source 274 also schematically includes electrical conduits that communicate with a data bus on loader 200 to enable communication between the tool's controller and the electronic devices of loader 200.

2 and 3, frame 210 supports and surrounds power system 220, so that various components of power system 220 are not visible. 4 includes a diagram of the various components of power system 220. Power system 220 includes one or more power sources 222 that can generate and/or store power for use in various mechanical functions. In the power machine 200, the power system 220 includes an internal combustion engine. Other power machines may include electric generators, rechargeable batteries, various other power sources, or combinations of power sources that can provide power to a given power machine component. Power system 220 also includes a power conversion system 224 operably coupled to power source 222 . Power conversion system 224 is coupled to one or more actuators 226 which in turn perform the functions of a power machine. The power conversion system 224 of various power machines may include various components including mechanical transmissions, hydraulic systems, and the like. The power conversion system 224 of the power machine 200 includes a pair of hydrostatic drive pumps 224A and 224B that are selectively controllable to provide power signals to drive motors 226A and 226B. Drive motors 226A; 226B are in turn operably coupled to axles, respectively, with drive motor 226A coupled to axles 228A; 228B and drive motor 226B coupled to axles 228C; 228D. Axles 228A-D are in turn coupled to traction elements 219A-D. Drive pumps 224A and 224B are mechanically, hydraulically and/or electrically coupled to operator input devices to receive operating signals to control the drive pumps.

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 have output of either a single hydraulic pump, a single drive motor of the power machine 200, or an individual drive motor. controlled together through Various other configurations and combinations of hydraulically driven pumps may be advantageously used.

The power conversion system 224 of the power machine 200 also includes a hydraulic tool pump 224C operably coupled to the power source 222. Hydraulic tool pump 224C is operably coupled to work actuator circuit 238C. Task actuator circuit 238C includes lift cylinder 238 and tilt cylinder 235 as well as control logic to control operation. Control logic selectively authorizes actuation of lift cylinders and/or tilt cylinders in response to operator input. In some machines, work actuator circuit 238C also includes control logic to selectively provide pressurized hydraulic fluid to the attachment tool. The control logic of the power machine 200 includes an open center, three-spool valve in a series arrangement. The spool is arranged to give priority to the lift cylinder, followed by the tilt cylinder and pressurized fluid to the attached tool.

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 concepts of the present invention described below can be realized. Embodiments disclosed in the present invention can be realized on power machines generally described by loaders, such as the power machine 100 shown in the block diagram of FIG. 1, and more specifically the track loader 200, unless specifically stated otherwise. Unless otherwise stated, the concept of the present invention described below is not limited to the environment specifically described above.

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

One or more input devices, generally denoted as input device(s) 286, communicate with controller 282 to allow delivery of driver input commands. The operator may manipulate the input device(s) 286 to provide user input signals to the controller 282, including generally according to well-known input and data transfer protocols. In some examples, one or more of input devices 286 may be configured as a combination input/output device according to various known configurations.

In some examples, input device(s) 286 may include a user input interface 287. For example, user input interface 287 may be the display itself (e.g., a touchscreen display device) or buttons, switches, and/or keypads or associated with the display and may provide input to a user based on signals received from controller 282 or another source. It may consist of a display device capable of receiving input from a user via one or more input devices, such as other suitable devices capable of providing information. User input interface 287 may also be a set of input devices as described above that can be operated by the driver without a corresponding display.

In some examples, the plurality of input devices may be configured to provide commands, receive signals, or control the operation of a power machine. In the example shown, controller 282 also operates starting mechanism 288 as well as power conversion system 224 (see FIG. 4), actuator 226 (see FIG. 4), and working actuator circuit 238C (see FIG. 4). ) communicates with an input device configured as ). Accordingly, the controller 282 may include power conversion system 224, actuator 226, auxiliary systems 289, as well as input from starting mechanism 288 to prompt commanded starting of power source 222 (e.g., internal combustion engine). ) (e.g., HVAC system, radio, etc.) or other inputs to selectively actuate devices in task actuator circuit 238C. Accordingly, various power machine functions are controlled.

According to one example, starting mechanism 288 may be configured as an ignition switch (or power source switch) that includes a switch operated by a physical key, button, toggle, etc. In some cases, startup mechanism 288 may be integrated with another one of the input device(s) 286, including user input interface 287. In some cases, activation of the start-up mechanism 288 may trigger a start-up operation as well as start-up of the power source generally (e.g., an initialization operation for the user input interface 287 or other subsystems of the control system 280). can be triggered).

In general, various other configurations are possible, including configurations in which the control system communicates with additional power machines or other functional subsystems. Accordingly, the principles of access and operational control discussed herein can be readily applied in connection with a variety of other power machine functions or power machine subsystems. Additionally, although controller 282 is schematically shown as a single component, other configurations may include multiple controllers that may be distributed on the power machine or elsewhere, as noted above.

Through appropriate configuration of control system 280 or another similar control system, the power machine may be configured such that certain power machine functions (e.g., full, partial, or zero functions) are available during the start-up process. Additional power machine features may also be available once authorization for the operator has been properly verified, including, where appropriate, a wireless connection between the mobile device and the power machine to identify the presence of the authorized user and any associated priorities or restrictions.

For example, the controller 282 may be configured to implement a temporary start-up mode during the start-up process of the power machine, wherein limited power machine functions are limited to the power machine 222 (e.g., through control of the start-up mechanism 288), hydraulics, etc. is selectively activated in one or more of the work group system (e.g., via work actuator circuit 238C in FIG. 4), power conversion system 224, actuator 226, auxiliary system 289, or other related power machine system. . Correspondingly, certain other power machine functions may not be activated (e.g., locked out) by the controller 282 while the power machine 200 is in a start-up mode.

While continuing to operate within the startup mode, control system 280 may also identify potential wireless connections with one or more mobile devices, preferably using a known wireless communication protocol to establish a wireless connection with the device(s). You can also use it. For example, the availability of a particular mobile device may be identified using Bluetooth or another near-field communication protocol and a connection may be established accordingly, allowing wireless exchange of information (e.g., IMEI or other identifier of the mobile device). Alternatively, the mobile device may use known wireless communication protocols to identify control system 280 and establish wireless access with the control system. However, only mobile devices that have previously been connected to the control system 280 (e.g., by pairing via a Bluetooth protocol) can establish a wireless connection with the control system.

Once the mobile device is identified, control system 280 can determine if and how to use the powertrain function based on the mobile device's identification. For example, if the wireless connection indicates that the mobile device is associated with a driving profile that includes certain permissions and operating priorities, control system 280 may allow operation of the power machine in accordance with those permissions and operating priorities. In contrast, if a wireless connection is not established with a mobile device or is established with a mobile device not associated with a driving profile, control system 280 may continue to allow limited (e.g., no) powertrain functionality accordingly (e.g., , subject to predetermined permissions of the startup mode).

In this regard, with reference to FIGS. 6 and 5 , an exemplary start-up process method 300 for accessing the functions of the power machine 200 that may be executed by the controller 282 and control system 280 generally is provided. presented. System 280 (FIG. 5). Although reference is made specifically to power machine 200, the methods disclosed herein, including those shown in FIG. 6, can be implemented generally on a variety of other power machines.

According to the example shown, the method 300 may begin at block 302 by placing the power machine 200 in a start-up mode. For example, control system 280 may initiate user input interface 287 (see FIG. 5) or provide input to another device operably connected to a power source (e.g., battery) of power machine 200. . In some examples, a driver may trigger execution of method 300 by manually operating (e.g., into the run position) starting mechanism 288 to activate a power source (e.g., start an engine). Correspondingly, under operation of the start-up mechanism 288, the power machine 200 includes a user input interface 287 to allow access to restricted power machine functions in block 304 in accordance with the authorization of the start-up mode. Power may be applied to one or more computing devices on the device. .

As noted generally above, during a start-up mode that defines limited power machine functionality, the operator of the power machine 200 may allow the engine or other primary power source to be activated, or be driven only by an auxiliary power source (e.g., a small battery). operation may be permitted. It may not be possible to command the operation of certain actuators (e.g., work group actuators) or perform certain operations (e.g., move lift arms, increase engine speed above idle, or travel faster than critical ground speed). However, in other examples, restricted power machine functions may include zero access to power machine functions. In this regard, for example, certain computer systems may be initialized, but power machine operation may not be available for actual control even when the main power source (e.g., engine) is started. In some cases, a power machine may not have an engine but may have a power source such as a battery pack. In these machines, the battery power source management system may inhibit power transmission to the actuator until communication with the mobile device is established.

In some cases, user input interface 287 may be used during a start-up mode to allow an operator to manipulate user input interface 287 to control specific functions of power machine 200, such as one or more devices of assistance system 289. The power source can be turned on. According to some examples, the limited functionality of the power machine 200 during the start-up mode may include operation of one or more work elements, such as work actuator circuit 238C, auxiliary hydraulic system 291, power conversion system 224, various traction elements, etc. can respond to restricted access.

In general, operation of a power machine in a starting mode may correspond to starting operation of the power machine from a non-power state (e.g., with the engine not running). However, in some cases the power machine may be otherwise placed in a start-up mode (block 302). For example, a powertrain may operate in a start mode (e.g., with limited powertrain functionality) due to intermediate operator action or other events (e.g., locking of a touchscreen or other input device, etc.) after the engine has already started.

Continuing, controller 282 may also be configured to establish a wireless connection to mobile device 290 (e.g., via Bluetooth or Wi-Fi communication) at block 306. According to some examples, controller 282 may automatically begin searching for a wireless connection for mobile device 290 upon receipt of power (e.g., after the powered machine is placed in start-up mode at block 302), but not in start-up mode. Other sequences are also possible, including sequences in which more than one wireless connection can be established before the start of. According to another example, the mobile device may detect the presence of controller 282 and establish a connection to the controller (at block 306).

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

Thus, for example, for a power machine currently operating with limited power machine functionality, the controller 282 may establish a connection with the connected mobile device 290 at block 306 and create a corresponding operating profile for the power machine 200. Once selected, controller 282 may sometimes allow access to additional power machine functions corresponding to the permissions or settings of the operating profile selected at block 308. According to some examples, additional power machine functions permitted from operation at block 308 may include actuation of traction elements of power machine 200 or may include actuation of work elements. For example, the user may not be permitted to drive the power machine 200 or operate the lift arms or tools of the power machine during the start-up mode, but once a connection with the associated mobile device is established at block 306, Execution of the corresponding function may be permitted based on the permissions of the associated driving profile. According to some examples, for a particular operator, the permitted additional powertrain functions of block 308 may include full powertrain functions without access restrictions.

As discussed above, the power machine 200 may store a plurality of operating profiles, each operating profile comprising one or more operating priorities, one or more operating permissions (e.g., a list or entitlement for permitted or blocked functions), Or it may include one or more other settings, some of which may or may not be unique to a particular driver. In this regard, for example, the driving profile may include settings for priorities of auxiliary system 289 functions, power conversion system 224, auxiliary hydraulic system 291 or work actuator circuit 238C, etc. In some cases, operating limits for these systems can be set within the driving profile, including vehicle speed limits, work element operating speed limits, geographic restrictions, etc. Accordingly, in one example, a driving profile for a driver with a certain level of experience may include permissions appropriate for that level of experience, which may include partial or full restrictions on operating certain elements of the job.

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

Referring now to Figures 5 and 7-10, various example user interfaces for user input interface device 287 are shown. 7 illustrates a user interface 400 for displaying current mobile device status 402 based on an established connection with a first mobile phone 290 associated with a corresponding driving profile. User interface 400 also displays potential connections 404 with mobile devices 290 and 290' within the sensing range of controller 282. Thus, for example, a driver may be provided with the option of connecting (or disconnecting) with a desired mobile device 290, 290' from a list of potential connections 404. Alternatively (or additionally), as previously described, controller 282 may sometimes determine connection order based on proximity, signal strength, or a predetermined priority list.

8 shows an example user interface 400' for creating an association 406 between an operating profile 410 of a power machine 200 and a mobile device 290 within the detection range of the controller 282. . Although a variety of approaches are possible, user interface 400' can provide a relatively simple process for associating a mobile device with a driving profile 410. For example, after the driver has indicated appropriate authorization to use the powered machine 200 (e.g., via another mobile device, manual input, etc.) and identified the driving profile 410 as relevant to the driver (e.g., User interface 400' may automatically (or upon request) provide the option to associate driving profile 410 with a connected (or available) mobile device (via previous login by the driver). Thus, for example, if mobile device 290 is already connected to a powertrain, the driver can create a driving profile with mobile device 290 relatively easily, including simply selecting the “Generate Key” (or similar) icon or button. It can be connected to (410).

According to some examples, in order to create an association with mobile device 290, it may be necessary that the relevant driving profile is not already associated with the mobile device. According to some examples, in order to create an association with mobile device 290, it may be required that mobile device 290 not previously been associated with another driving profile. According to some examples, only selected drivers (e.g., managers) may be allowed to associate specific mobile devices with specific driving profiles.

In some cases, removing the connection between a mobile device and a driving profile can proceed similarly, but in reverse. For example, Figure 9 shows an example user interface 400' for deleting an association 408 between a mobile device 290 and an operating profile 410 of a power machine 200. Thus, for example, a driver may relatively easily remove the association of a driving profile with mobile device 290, including simply selecting a “delete key” (or similar) icon or button. According to some examples, the association between mobile device 290 and driving profile 410 may be removed regardless of whether mobile device 290 is currently wirelessly connected to power machine 200. According to some examples, only selected drivers (e.g., administrators) may be permitted to remove associations of specific mobile devices with specific driving profiles.

In some cases, association with a specific driving profile can be easily switched between different mobile devices. For example, FIG. 10 illustrates converting an 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. An exemplary user interface 400"' is shown for. Thus, for example, a driver may relatively easily switch connections between a mobile device and a driving profile, including simply selecting a "replace key" (or similar) icon or button. This may be useful, for example, when a driver changes mobile devices or wants to associate another one of multiple mobile devices with a driving profile.
