Description

Technical Field

[0001] This disclosure relates to the field of outdoor tool technology, and in particular to control systems and control methods for outdoor work vehicles. Background Technology

[0002] Outdoor work vehicles are widely used in landscaping, agriculture, and other fields. Taking lawnmowers as an example, traditional lawnmowers, mainly push-type mowers and similar machines, have low automation, low efficiency, and require significant physical exertion, potentially causing harm to the human body. For work areas requiring year-round maintenance of large areas of lawn (e.g., golf courses, football fields, courtyard lawns, municipal parks, tourist attractions, farms, orchards, and overgrown fields), ride-on lawnmowers offer long battery life, flexible operation, and high efficiency, making them well-suited for these conditions and avoiding fatigue and even injury caused by prolonged work.

[0003] Based on energy source, there are currently two main types of ride-on lawnmowers: gasoline engine type and lithium battery rechargeable type. Compared to gasoline engines, lithium battery rechargeable ride-on lawnmowers have significant advantages: all-weather zero emissions, zero fuel consumption, low noise, and simple maintenance (no gasoline, no engine oil, no air filter, no spark plugs, no fuel storage, etc.). In addition, gasoline engines are similar to traditional fuel vehicles, with a complex overall mechanical structure and a differential gear for drive wheel control; while lithium battery rechargeable ride-on lawnmowers use electric motors instead of a fuel engine for drive wheels, allowing for independent control of two (or four) drive wheel motors to achieve straight-line, reverse, turning, and zero-steering motion control, reducing the overall structural complexity of the vehicle and making the control more flexible.

[0004] For safety reasons, to prevent accidental operation and start-up of ride-on lawnmowers, they are generally designed with a physical key switch. This design is inherited from gasoline-powered ride-on lawnmowers. However, this approach can lead to some problems, such as:

[0005] 1. The additional key and key switch recognition circuit increase costs, and the key switch signal recognition is wired, which increases the complexity of the wiring harness (because there are already many wiring harnesses inside the vehicle), and also increases costs.

[0006] 2. The key switch signal is unreliable. In some very bumpy environments, the key may jump around, causing abnormal shutdown.

[0007] 3. The keys are easily lost, causing inconvenience and reducing customer satisfaction. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this disclosure can be combined with each other.

[0053] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings, so that those skilled in the art to which this disclosure pertains can readily implement it. This disclosure may be embodied in many different forms and is not limited to the embodiments described herein.

[0054] In this disclosure, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic represented in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. Furthermore, the specific features, structures, materials, or characteristics represented may be combined in any suitable manner in any one or a group of embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples represented in this disclosure, as well as the features of those different embodiments or examples.

[0055] Furthermore, the terms "first" and "second" are used for illustrative purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the representation of this disclosure, "a set" means two or more, unless otherwise explicitly specified.

[0056] For the purpose of clarity, devices unrelated to the description are omitted, and the same or similar components throughout the specification are given the same reference numerals.

[0057] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0058] While the terms first, second, etc., are used in some examples herein to refer to various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, first interface and second interface, etc., are used. Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms “comprising,” “including,” indicate the presence of the stated feature, step, operation, element, module, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, modules, items, kinds, and / or groups. The terms “or” and “and / or” as used herein are interpreted as inclusive, or mean any one or any combination thereof. Thus, “A, B, or C” or “A, B, and / or C” means “any one of: A; B; C; A and B; A and C; B and C; A, B, and C.” Exceptions to this definition will only occur if the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0059] The technical terms used herein are appropriate only for specific embodiments and are not intended to limit the scope of this disclosure. The singular form used herein includes the plural form unless the statement explicitly indicates otherwise. The word "comprising" as used in this specification means to specify a particular characteristic, region, integer, step, operation, element, and / or component, and does not exclude the presence or addition of other characteristics, regions, integers, steps, operations, elements, and / or components.

[0060] Although not explicitly defined, all terms, including technical and scientific terms used herein, shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Terms defined in commonly used dictionaries shall be further interpreted as having a meaning consistent with the relevant technical literature and the message of the present disclosure, and shall not be over-interpreted as having an ideal or overly formulaic meaning unless otherwise defined.

[0061] In related technologies, outdoor work vehicles are gradually adopting new energy batteries as their power source to replace traditional fuel power sources, and drive motors to replace fuel engines. However, although the power drive-related parts have been upgraded, some other designs still rely on fuel-powered vehicles, and these designs have certain shortcomings.

[0062] Take a ride-on lawnmower as an example. For safety reasons, to prevent accidental operation and start-up of fuel-powered ride-on lawnmowers, a physical key switch is generally designed to unlock the machine before it can be started. Lithium-ion rechargeable ride-on lawnmowers also use this physical key switch design. However, physical key switches have several drawbacks, such as increased cost and wiring complexity due to the associated structure and signal recognition circuitry, the possibility of the switch tripping and causing the machine to stop in real-world environments, and the fact that the key needs to be stored separately and is therefore prone to loss.

[0063] Therefore, embodiments of this disclosure focus on providing outdoor work vehicles, replacing the physical key switch unlocking scheme with an unlocking scheme that implements information verification on outdoor work vehicles, thereby eliminating the various problems caused by using a physical key switch.

[0064] The outdoor work vehicles involved in this disclosure may include one of the following: lawnmowers, snowplows, seeders, forklifts, and utility task vehicles (UTVs).

[0065] like Figure 1 The diagram shows a structural schematic of an outdoor work vehicle according to an embodiment of the present disclosure.

[0066] The outdoor work vehicle 100 includes: a carrying device 110, a frame 120, a walking mechanism 130, and a working mechanism 140. In this embodiment, the outdoor work vehicle 100 is exemplarily shown as a ride-on lawnmower. The carrying device may include at least one of a seat or a standing platform. Figure 1 The illustration only shows an example of the support device 110 including a seat. The seat or the standing platform is used for workers to sit or stand. That is, the outdoor work vehicle can provide a riding or standing working mode. Furthermore, the structure of the seat and the standing platform can be flexibly switched, that is, the working mode of the outdoor work vehicle can be flexibly switched between riding and standing working modes according to the actual needs of the user.

[0067] The carrying device 110 is for users to ride on. The frame 120 is used to load the carrying device 110, the working mechanism 140, and the traveling mechanism 130.

[0068] The walking mechanism 130 is used to propel the outdoor work vehicle 100. In some embodiments, the walking mechanism 130 may be implemented as a wheel mechanism, including, for example, three wheels, four wheels, or more tires. Exemplarily, Figure 1The image shows a pair of front wheels 131 and 132 and a pair of rear wheels 133 and 134. The pair of rear wheels 133 and 134 can serve as drive wheels (i.e., left and right drive wheels), and the pair of front wheels 131 and 132 can serve as driven wheels. In a further embodiment, the pair of front wheels 131 and 132 can be connected to the frame 120 via a steering mechanism, enabling steering during rotation. In other embodiments, the walking mechanism 130 can also be implemented with other structures, such as a tracked structure, depending on the scenario.

[0069] The working mechanism 140 is used for operations. As an example, corresponding to the outdoor work vehicle 100 being a lawnmower, the working mechanism 140 is implemented as blades 141 and 142 for mowing grass.

[0070] In some embodiments, the walking mechanism 130 and the working mechanism 140 may be driven by motors. For example, the walking mechanism 130 may be connected to a walking motor for being driven by the walking motor. The working motor may be connected to a working motor for being driven by the working motor.

[0071] In some embodiments, the outdoor work vehicle 100 may further include an operating component 150 for accepting user operation to control the operation of the outdoor work vehicle 100, such as walking or working. As an example, the operating component 150 may include control handles, such as a left control handle 151 and a right control handle 152. Based on the operating component 150, the user can control the operation of the walking motor and / or the working motor.

[0072] In some embodiments, the outdoor work vehicle 100 may further include a control panel 160. As an example, the control panel 160 may be configured with interactive elements, such as operation buttons, a display screen (not shown), etc. In yet other embodiments, the display screen may also be independently configured, for example, by forming a support frame (not shown) at the front lower position of the support device 110, with the display screen positioned on the support frame and its display surface facing the support device 110.

[0073] The outdoor work vehicle 100 can be controlled by a controller system to perform walking and / or work. For example, the walking motor for driving the walking mechanism 130 can be controlled by a walking motor controller, and the work motor for driving the work mechanism 140 can be controlled by a work motor controller.

[0074] like Figure 2 The diagram shown illustrates the structure of a controller system for an outdoor work vehicle according to an embodiment of this disclosure.

[0075] exist Figure 2In this example, the outdoor work vehicle 200 is exemplified as a lawnmower. Its walking mechanism 230 includes a left drive wheel 231 and a right drive wheel 232, and its working mechanism 240 includes a left cutter 241 and a left cutter 242. The walking motor 270 of the outdoor work vehicle 200 includes a left drive wheel motor 271 connected to and driving the left drive wheel 231, and a right drive wheel motor 272 connected to and driving the right drive wheel 232. The working motor 280 of the outdoor work vehicle 200 includes a left cutter motor 281 connected to and driving the left cutter 241, and a right cutter motor 282 connected to and driving the left cutter 242.

[0076] In this embodiment, the controller system 290 includes: a vehicle control unit (VCU), a drive motor controller 292, a work motor controller 293, and a battery management system (BMS). Specifically, the drive motor controller 292 includes: a left drive controller 2921 connected to and controlling the left drive wheel motor 271, and a right drive controller 2922 connected to and controlling the right drive wheel motor 272. The work motor controller 293 includes: a left cutter controller 2931 connected to and controlling the left cutter motor 281, and a right cutter controller 2932 connected to and controlling the right cutter motor 282.

[0077] The outdoor work vehicle 200 includes a power supply unit 294, which includes a battery 2941 and a battery management system 2942. As an example, the battery 2941 can be a lithium-ion battery, a lead-acid battery, a nickel-metal hydride battery, or other types of power batteries. The battery management system 2942 manages the power supply from the battery 2941 to the various controllers and motors of the outdoor work vehicle 200.

[0078] The vehicle controller 291 is communicatively connected to the travel motor controller 292, the work motor controller 293, and the battery management system 2942. In some embodiments, the communication connection can be implemented as a Controller Area Network (CAN) connection. The vehicle controller 291, the left travel controller 2921, the right travel controller 2922, the left cutter controller 2931, and the right cutter controller 2932 each have a unique address in the CAN network, and they communicate with each other using their respective addresses.

[0079] The outdoor work vehicle 200 also includes an operating component 250. As an example, the operating component 250 includes a left operating handle 251 and a right operating handle 252. The left operating handle 251 is connected to the left travel controller 2921 and is used to receive user input to output a control signal to the left travel controller 2921 for the left drive wheel 231. The right operating handle 252 is connected to the right wheel controller and is used to receive user input to output a control signal to the right travel controller 2922 for the right drive wheel 232. Thus, the left and right drive wheels 231 and 232 can be controlled via the left and right operating handles 251 and 252, allowing the outdoor work vehicle 200 to move in the desired manner. The electrical signals generated by the operation of the left and right operating handles 251 and 252 can be analog signals, such as analog current or voltage signals.

[0080] The operating component 250 may further include a cutter switch 253. The cutter switch 253 is used to accept user operation and output a switch signal to the vehicle controller 291. The vehicle controller 291 sends corresponding mowing commands to the left cutter controller 2931 or the right cutter controller 2932 to control the left cutter motor 281 and the right cutter motor 282. In some embodiments, the vehicle controller 291 synchronously controls the left cutter controller 2931 and the right cutter controller 2932 to cause the left cutter 241 and the left cutter 242 to work and stop synchronously. Alternatively, in other embodiments, the vehicle controller 291 may independently control the left cutter controller 2931 and the right cutter controller 2932 to cause the left cutter 241 and the left cutter 242 to work or stop independently of each other. Optionally, the cutter switch 253 is configured with two positions, "on" and "off," corresponding to the synchronous control mode, which control the left cutter 241 and left cutter 242 to open and close synchronously. Alternatively, the cutter switch 253 is configured with four positions, corresponding to the "on" and "off" of the left cutter 241 and the "on" and "off" of the left cutter 242, respectively, corresponding to the independent control mode.

[0081] Understandably, the number of cutter motors and cutter controllers should be matched with the number of cutters. If the number of cutters increases, for example, to 3 or 4, then the number of cutter motors and cutter controllers should also increase accordingly.

[0082] Understandable, Figure 2 The distribution of the controllers shown in the diagram is just an example. In actual application scenarios, the controllers can be physically combined (such as integrated) or separated according to requirements, and are not limited to the example shown in the diagram.

[0083] For example Figure 3The diagram shown illustrates the structure of a controller system for an outdoor work vehicle according to another embodiment of this disclosure.

[0084] and Figure 2 The difference between the embodiments is that, Figure 3 Some controllers in the 390 controller system are integrated into one unit. For simplicity, Figure 3 The details of the mechanisms are omitted. Specifically, the left travel controller 2921 and the right travel controller 2922 are integrated with the vehicle controller 291 into a single vehicle and travel controller 391. Furthermore, an integrated cutter controller 392 provides overall control of multiple cutter motors 393 (e.g., 2, 3, or 4 cutter motors). The vehicle and travel controller 391, the integrated cutter controller 392, and the battery management system 3942 are interconnected, for example, via a CAN bus connection. The battery 3941 provides power.

[0085] The left operating handle 351 and the right operating handle 352 are communicatively connected to the vehicle and travel controller 391, which connects to and controls the left drive wheel motor 371 and the right drive wheel motor 372.

[0086] It should be noted that, in Figure 2 and Figure 3 As taught in the embodiments, other integration / distribution schemes can also be adopted among at least one controller included in the outdoor operation vehicle, which will not be listed here, but are all within the protection scope of this disclosure.

[0087] In other embodiments, the vehicle controller may be a vehicle and battery controller integrated with the battery management system. For example, the battery management system may be integrated with a motor controller (such as a drive motor controller and / or a work motor controller) into a battery and motor controller. For another example, the vehicle controller, drive motor controller, work motor controller, and battery management system may be integrated into a single combined controller assembly. As an example, integration may refer to integration within the same circuit board or the same package.

[0088] In some embodiments, the carrier of a ride-on lawnmower may be equipped with a carrier sensor, for example, located under the carrier. The carrier sensor can be used to detect whether the carrier is occupied. The carrier sensor may be directly or indirectly communicatively connected to at least one controller, such as a vehicle controller or a controller integrated with a vehicle controller.

[0089] Outdoor work vehicles pose inherent dangers during operation; for example, the cutting tool can cause cuts. Therefore, unlike ordinary vehicles, outdoor work vehicles require locking for safety reasons. Only after unlocking can the vehicle be started, and further, its walking and working functions can be activated. In other words, outdoor work vehicles require multiple layers of protection.

[0090] like Figure 4A The diagram shown illustrates the functional modules of the control system for an outdoor work vehicle in one embodiment of this disclosure.

[0091] In this embodiment, the control system 400 of the outdoor work vehicle includes an unlocking component 420 and a control component 410.

[0092] The unlocking component 420 is installed on the outdoor work vehicle and is adapted to acquire the verification information input by the user and output a corresponding output signal based on the verification information.

[0093] The control component 410 is disposed on the outdoor work vehicle and coupled to the unlocking component 420. The control component 410 includes a motor switch command unit 411, which, when activated, sets the drive motor 430 and / or the work motor 440 of the outdoor work vehicle to an active state. The control component 410 is in an unlocked state in response to determining that the verification information has been verified successfully based on the output signal. In the unlocked state, the motor switch command unit is in a state that can be activated. In some embodiments, the control component 410 includes a controller system 490. The controller system 490 may be exemplified as... Figure 2 or Figure 3 The controller systems 290 and 390 in the embodiments.

[0094] The motor switch command unit 411 can be implemented by hardware circuitry, software program modules, or a combination thereof on a controller (e.g., a vehicle controller) in the controller system 490. As an example, when the motor switch command unit 411 is activated, the controller to which it resides can output activation signals to the corresponding travel motor controller and / or work motor controller.

[0095] As further exemplified, reference can be made to Figure 4B The diagram shown illustrates the functional modules of the motor switch command unit according to an embodiment of this disclosure.

[0096] As an example, the motor switch command unit 411 may include: a walking motor switch command unit 4111 and a work motor switch command unit 4112.

[0097] The travel motor switch command unit 4111 sets the travel motor to an active state when it is turned on. For example, it causes the vehicle controller to output a first activation signal to the travel motor controller.

[0098] The work motor switch command unit sets the work motor to an active state when it is turned on. For example, it instructs the vehicle controller to output a second activation signal to the work motor controller to activate the work motor.

[0099] In some embodiments, the action of verifying the information to be verified can be performed by the unlocking component, and an unlock signal is generated and output to the control component when the verification is successful. The control component then enters an unlocked state based on the unlock signal. Alternatively, in other embodiments, the unlocking component may also output the input information to be verified (or its encoded information) to the control component for verification, and enter an unlocked state after successful verification.

[0100] The control system of the outdoor work vehicle in this embodiment of the present disclosure verifies the information to be verified by the user, thereby replacing the physical key switch for the outermost locking / unlocking protection of the outdoor work vehicle. This solves the problems of cost, complex wiring harness, easy jumping and shutdown due to bumps, and easy loss of the physical key switch's matching circuit.

[0101] Only after successful verification can the walking and / or working functions of the outdoor work vehicle be activated, granting access to and use of the walking motor and / or working motor. Therefore, the design in this embodiment offers advantages such as enhanced security, reliability, convenience, and reduced risk of loss, while also improving vehicle usability and facilitating authorization management. For example, in a scenario where a physical key switch is used to unlock the outdoor work vehicle, if the father leaves home with the physical key switch, no one at home can unlock the vehicle, making it inconvenient to use. However, if verification information (such as a password) is used, the father only needs to remotely provide the verification information to a family member, who can then unlock and use the vehicle using the password, providing greater flexibility in controlling the outdoor work vehicle.

[0102] It should be noted that the structure of the unlocking component and the control component can change accordingly depending on the function they implement. For example, if the function of verifying the information to be verified is located in the unlocking component or the control component, the structure of the unlocking component and the control component will change accordingly.

[0103] like Figure 4C The diagram shows a functional module schematic of the components in the control system 400a of an outdoor work vehicle according to an embodiment of the present disclosure.

[0104] exist Figure 4CIn this configuration, the unlocking component 420a includes an input unit 421 and an unlocking detection unit 422. The control component 410a includes only a controller system 490. The unlocking detection unit 422 communicates with the controller system 490.

[0105] The unlock detection unit 422 can communicate with one of the controllers in the controller system 490, or, in other examples, the unlock detection unit 422 can be integrated into one of the controllers in the controller system 490.

[0106] The input unit 421 can communicate with the unlock detection unit 422 by communicating with the controller system 490, or the input unit 421 can communicate directly with the unlock detection unit 422.

[0107] like Figure 4D The diagram shows a functional module schematic of a component in a control system 400b according to another embodiment of this disclosure.

[0108] exist Figure 4D In, with Figure 4C The difference in the control system is that the unlocking component 420b only includes an input unit 421, which is used to accept user input and output the information to be verified. The control component 430b includes an unlocking detection unit 422 and a controller system 490.

[0109] The unlock detection unit 422 can be communicatively connected to a controller in the controller system 490. Alternatively, in other examples, the unlock detection unit 422 can also be integrated into a controller in the controller system 490.

[0110] The input unit 421 is adapted for users to input information to be verified. In some embodiments, the input unit 421 may be implemented as a password input device, such as a keyboard, for inputting a password as verification information. In some embodiments, the input unit 421 may be implemented for inputting biometric information as verification information. Biometric information may include one or more combinations of face, finger / palm print, retina, voiceprint, etc. As a corresponding example, the input unit 421 may be implemented as an image acquisition device, such as a camera, for acquiring biometric information such as face, finger / palm print, and retina. As a corresponding example, the input unit 421 may be implemented as a finger / palm print sensor for acquiring finger / palm print biometric information. As a corresponding example, the input unit 421 may be implemented as a recording device, such as a voice acquisition device, for inputting sound signals for extracting voiceprint information and verification.

[0111] In some embodiments, the information to be verified may also be implemented as other specific signals. As a corresponding example, the input unit 421 may be implemented as a device equipped with one or more communication circuits such as Near Field Communication (NFC), Radio Frequency Identification (RFID), and Bluetooth, and is installed on the outdoor work vehicle to communicate and interact with external terminal devices to receive and verify the information to be verified (which may be specifically encoded). In possible embodiments, the external terminal device may be, for example, a mobile terminal such as a smartphone or tablet, or a dedicated terminal integrating only one type of communication circuit, such as a remote key.

[0112] In some embodiments, the input unit 421 may be positioned differently on the outdoor work vehicle depending on the type described above. The following examples illustrate this. Figure 1 Taking 100 outdoor work vehicles as an example, we will provide separate examples.

[0113] like Figure 5 The diagram shows a schematic of an outdoor work vehicle with an input unit located in one embodiment of the present disclosure.

[0114] exist Figure 5 In this example, the input unit 421 is implemented as a keyboard 421a, which is located on the control panel 160 of the outdoor work vehicle 100, adjacent to the front and below the carrying unit 110. This location allows a user riding on the carrying unit to easily reach the keyboard 421a to enter a password.

[0115] As an example, the keyboard 421a can be implemented as a physical keyboard, providing physical keys for the user to enter a password. Alternatively, in another example, the input unit 421 can be implemented as a display screen that can display a virtual keyboard. Optionally, the display screen can be a touchscreen to allow the user to input directly on the touchscreen.

[0116] like Figure 6 The diagram shows a structural schematic of an outdoor work vehicle with an input unit located in another embodiment of this disclosure.

[0117] exist Figure 6 In this example, the input unit 421 is implemented as a fingerprint sensor 421b, which is located on the control panel 160 of the outdoor work vehicle 100, adjacent to the front and below the carrier 110. This location allows a user riding on the carrier to easily reach out and touch the fingerprint sensor to input their fingerprint.

[0118] Understandably, the palmprint sensor can be placed in the same location as the fingerprint sensor.

[0119] like Figure 7The diagram shows a schematic of the structure of an input unit located on an outdoor work vehicle in another embodiment of the present disclosure.

[0120] exist Figure 7 In this example, the input unit 421 is implemented as an image acquisition device 421c for acquiring facial and / or retinal information. The image acquisition device 421c may be located on the upper part of the left operating handle 151 or the right operating handle 152 of the outdoor work vehicle 100, for example, at the top or a lower position. The example in the figure shows position A at the top of the right operating handle 152. This position is close to the user's face on the support device 110, facilitating the acquisition of facial and / or retinal information.

[0121] like Figure 8 The diagram shows a schematic of the structure of an input unit located on an outdoor work vehicle in another embodiment of this disclosure.

[0122] exist Figure 8 In this example, the input unit 421 is implemented as a voice acquisition device 421d, which may be located on the upper part of the left operating handle 151 or the right operating handle 152 of the outdoor work vehicle 110, for example, at the top or at a lower position. This position is close to the user's mouth, which facilitates the acquisition of the user's voice signal on the carrying device 110.

[0123] In some embodiments, the voice acquisition device may be positioned lower than the image acquisition device on the left or right operating handle.

[0124] like Figure 9 The diagram shows a schematic of the structure of an input unit located on an outdoor work vehicle in another embodiment of this disclosure.

[0125] exist Figure 9 In the example, the input unit is implemented as a wireless communication device 421e, which may have at least one wireless communication circuit among near field communication (NFC), radio frequency identification (RFID), Bluetooth communication, mobile communication (3G / 4G / 5G), etc., located in an outdoor work vehicle, and may be equipped with a peer device with the same communication protocol.

[0126] As an example, for wireless communication devices 421e with a short communication range, such as NFC or RFID tags, they can be located on the control panel 160 of the outdoor work vehicle 100, near the front and lower part of the carrying device. This location allows the user sitting on the carrying device 110 to easily input information by hand-holding and sensing the wireless communication device 421e (e.g., an NFC or RFID reader) to establish communication.

[0127] As an example, for communication methods like Bluetooth, which have a relatively long communication distance but require on-site communication, the wireless communication device 421e for Bluetooth communication on the outdoor work vehicle 100 can be located within the Bluetooth communication range of the smartphone.

[0128] As an example, for mobile communication (3G / 4G / 5G), the wireless communication device 421e can be implemented with a mobile communication circuit, allowing the insertion of a SIM card to access the mobile communication network for remote communication with a user's mobile terminal. In this example, the user's mobile terminal can remotely communicate with the wireless communication device 421e to remotely unlock the outdoor work vehicle 100.

[0129] Since the wireless communication device 421e has the ability to access mobile communication networks, it can also utilize its remote communication capabilities in conjunction with other information input methods to complete the input of information to be verified. For example, each outdoor work vehicle 100 may have an unlocking QR code containing specific network link information. The user scans the unlocking QR code with a mobile terminal to access the server pointed to by the specific network link information, and the server can generate information to be verified and transmit it to the outdoor work vehicle through a wide area network and / or a local area network. The wireless communication device 421e receives the information to be verified and transmits it to the unlocking detection unit 422 for verification. As an example, the QR code may be displayed on a screen located on the outdoor work vehicle 100, or it may be formed on the surface of the outdoor work vehicle by printing or printing methods.

[0130] For example, a user communicates with the server by operating a mobile application (APP) to trigger the server to send verification information to the outdoor work vehicle. The outdoor work vehicle may have a unique device ID, and the mobile APP may have a unique user ID preset. After the mobile phone establishes a wireless communication connection with the wireless communication device 421e on the outdoor work vehicle, a binding relationship between the device ID and the user ID can be established to determine the ownership of the outdoor work vehicle to the user and enable further use.

[0131] The unlock detection unit 422 is coupled to a controller in the controller system of the outdoor work vehicle. "Coupled" refers to a communication connection or integration into the controller. The controller can be a vehicle controller, a travel motor controller, a work motor controller, a battery management system, or a controller integrated from these in various ways. The unlock detection unit is adapted to verify the information to be verified, such as verifying whether one or more combinations of an input password, fingerprint / palm print, face, retina, voiceprint, NFC signal, RFID signal, and Bluetooth signal match a previously input. Furthermore, in response to successful verification of the information to be verified, the unlock detection unit can send an unlock signal to the coupled controller. The unlock signal is adapted to set the at least one controller to an unlocked state. In the unlocked state, the outdoor work vehicle cannot be activated by the user for travel or work. In the unlocked state, the travel and / or work functions of the outdoor work vehicle can be activated. Specifically, the vehicle controller can accept user commands and execute control, and the travel motor controller and / or work motor controller can be controlled by the vehicle controller to activate the travel motor and / or work motor to drive the movement of the travel mechanism and / or work mechanism.

[0132] In some embodiments, the unlock status can vary depending on different usage permissions. For example, there can be multiple usage permissions, such as only being able to use the walking function, only being able to use the work function, or being able to use both the walking function and the work function.

[0133] according to Figure 2 and Figure 3 It is understood that the controllers in the controller system communicate with each other. When multiple controllers are integrated, the unlock detection unit can form a communication path with the input unit through the communication connection between the controllers to obtain and verify the input information to be verified. Alternatively, when multiple controllers are integrated into one, the unlock detection unit can also communicate with the input unit through a communication connection with that single controller.

[0134] Alternatively, the unlock detection unit may be implemented as a hardware circuit, software program, or hardware circuit combined with software program in at least one controller (e.g., vehicle controller) capable of verifying the information to be verified.

[0135] Please see Figures 10 to 17 This illustration shows a schematic diagram of the connection between the unlock detection unit 422 and a controller system with different controller integration forms in one embodiment of the present disclosure.

[0136] like Figure 10 The diagram shown illustrates the connection between the unlocking detection unit and the vehicle controller in one embodiment of this disclosure. It should be noted that... Figures 10-17The diagram shows the communication connections between controllers, but does not show all the power supply lines from the battery management system to other controllers. Therefore, it does not mean that the power supply lines from the battery to each controller do not exist.

[0137] In this embodiment, the vehicle controller 1010 is communicatively connected to the walking motor controller 1020, the work motor controller 1030, and the battery management system 1040, and the unlock detection unit 422 can be communicatively connected to the vehicle controller 1010.

[0138] like Figure 11 The diagram shown illustrates the connection between the unlocking detection unit and the battery management system in one embodiment of this disclosure.

[0139] In this embodiment, the vehicle controller 1010 is communicatively connected to the walking motor controller 1020, the work motor controller 1030, and the battery management system 1040, and the unlock detection unit 422 can be communicatively connected to the walking motor controller 1020 (or the work motor controller 1030).

[0140] like Figure 12 The diagram shown illustrates the connection between the unlocking detection unit and the battery management system in one embodiment of this disclosure.

[0141] In this embodiment, the vehicle controller 1010 is communicatively connected to the walking motor controller 1020, the work motor controller 1030, and the battery management system 1040, and the unlock detection unit 422 is communicatively connected to the battery management system 1040.

[0142] like Figure 13 The diagram shown illustrates the connection between the unlocking detection unit and the vehicle and motor controller in one embodiment of this disclosure.

[0143] In this embodiment, the vehicle controller 1010, the travel motor controller 1020, and the work motor controller 1030 are integrated into a vehicle and motor controller 1311, and are communicatively connected to the battery management system 1040. The unlock detection unit 422 is communicatively connected to the vehicle and motor controller 1311.

[0144] like Figure 14 The diagram shown illustrates the connection between the unlocking detection unit and the combined motor controller in one embodiment of this disclosure.

[0145] In this embodiment, the walking motor controller 1020 and the work motor controller 1030 are integrated into a combined motor controller 1490, which is communicatively connected to the vehicle controller 1010 and the battery management system 1040. The unlock detection unit 422 is communicatively connected to the combined motor controller 1490.

[0146] like Figure 15 The diagram shown illustrates the connection between the unlocking detection unit and the vehicle and battery controller in one embodiment of this disclosure.

[0147] In this embodiment, the vehicle controller 1010 and the battery management system 1040 are integrated into a vehicle and battery controller 1510, and are communicatively connected to the travel motor controller 1020 and the work motor controller 1030. The unlock detection unit 422 is communicatively connected to the vehicle and battery controller 1510.

[0148] like Figure 16 The diagram shown illustrates the connection between the unlocking detection unit and the battery and motor controller in one embodiment of this disclosure.

[0149] In this embodiment, the battery management system 1040, the travel motor controller 1020, and the work motor controller 1030 are integrated into a battery and motor controller 1610, and are communicatively connected to the vehicle controller 1010. The unlock detection unit 422 is communicatively connected to the battery and motor controller 1610.

[0150] like Figure 17 The diagram shown illustrates the connection between the unlocking detection unit and the combined controller assembly in one embodiment of this disclosure.

[0151] In this embodiment, the vehicle controller 1010, the travel motor controller 1020, the work motor controller 1030, and the battery management system 1040 are integrated into a combined controller assembly 1710. The unlock detection unit 422 is communicatively connected to the combined controller assembly 1710.

[0152] like Figure 18 The diagram shows a schematic of a module for activating the travel motor and / or work motor of an outdoor work vehicle in one embodiment of this disclosure.

[0153] Considering the safety of outdoor work vehicles, various switching devices 1850 can be installed on outdoor work vehicles.

[0154] In possible embodiments, various switching devices 1850 may be coupled to the unlock detection unit 422 to transmit signals to the controller system 1820 (which may be any controller system in the previous embodiments, for example...) via the unlock detection unit. Figures 10-17One of them), for example, is sent to the vehicle controller 1810 (or a controller integrated with a vehicle controller, such as a vehicle and travel controller, a vehicle and battery controller, a combined controller assembly, etc.). As an example, the vehicle controller 1810 pre-stores a preset condition group 1811 related to the various switching devices 1850. When it is determined that the signals of the various switching devices 1850 meet the preset condition group 1811, it enables the connected travel motor controller 1820 and / or work motor controller 1830 to control the travel motor and / or work motor to drive the travel mechanism and work mechanism to operate.

[0155] Examples of embodiments of the various switching devices 1850 are provided. For instance, in the case of a ride-on lawnmower, the carrying device of the outdoor work vehicle may be equipped with a carrying device sensor 1851 to detect whether the carrying device 110 is occupied by a user. The outdoor work vehicle may include a start / stop switch 1852. The outdoor work vehicle may include an activation switch 1853 corresponding to the drive motor / work motor, such as a physical pressure switch or a graphical control (displayed as an icon on the screen) of the corresponding virtual button. Accordingly, the preset condition group 1811 may include:

[0156] Condition 1: The verification of the information to be verified input by input unit 421 is successful. The verification can be completed by the unlock detection unit.

[0157] Condition 2: The carrier sensor 1851 installed on the carrier device detects that the carrier device is occupied.

[0158] Condition 3: Actuation of the start / stop switch 1852 of the outdoor work vehicle.

[0159] Condition 4: The activation switch 1853 corresponding to the walking motor controller / operation motor controller receives the activation operation.

[0160] It should be noted that, in other embodiments, the carrier device sensor 1851, start / stop switch 1852, and activation switch 1853 may also be selected to be directly connected to the controller, such as a VCU or a controller integrated with a VCU, and the input unit 421 may be selected to be connected to the unlock detection unit 422 or at least one controller.

[0161] Of course, in some embodiments, the preset condition group may also include other conditions. For example, based on requirements such as normal operation and safety, the conditions for whether the operating parameters of electrical components in outdoor work vehicles meet the requirements (such as reaching preset thresholds or being within preset ranges), such as whether the voltage, current, and speed of the motor meet the requirements.

[0162] In some embodiments, the conditions in the preset condition group 1811 may have different priorities. For example, the start / stop switch 1852 is operated by the user to power on the outdoor work vehicle. When the outdoor work vehicle is powered on, the user inputs the verification information into the input unit 420. If the verification information is passed, the outdoor work vehicle is unlocked, and the occupancy status information of the carrier device sensor 1851 is used to determine whether it can move or work. For safety reasons, the walking mechanism and the working mechanism are not allowed to operate when no one is present. Therefore, if the occupancy status information indicates that the carrier device is not occupied, the activation switch 1853 cannot function. If the occupancy status information indicates that someone is on the carrier device, the activation switch 1853 can be operated by the user to activate the corresponding walking motor and / or working motor. Thus, the activation process of the walking motor and / or working motor can be: "Start / stop switch actuated → Information verification passed and unlocked → Carrier device occupied & activation switch accepts activation operation → Walking motor and / or working motor activated". Consequently, the walking function and / or working function can be used. Alternatively, in some embodiments, the unlocking component and controller system may be powered but locked and cannot be activated. In this case, the user can first input the information to be verified. Then, the activation process of the travel motor and / or the work motor can be: "Information verification passed and unlocked → start / stop switch actuated → load-bearing device occupied & activation switch accepts activation operation → travel motor and / or work motor activated".

[0163] In some embodiments, at least one controller (such as a VCU or a controller with an integrated VCU) may also be adapted to start a timer in response to the occupancy status information indicating that a user has left the carrying device. Furthermore, in response to the timer reaching a predetermined duration threshold, the operation of the outdoor work vehicle's travel motor and work motor may be suppressed to ensure vehicle safety and the safety of people in the surrounding area. Suppressing the operation of the travel motor and work motor may be achieved by: shutting off the power supply to the outdoor work vehicle, or putting the vehicle's overall controller into a sleep state, thereby prohibiting the controller from responding to actions of the operating components.

[0164] When the input unit 422 is implemented as a display screen, the display screen can provide a graphical human-computer interaction interface (GUI) for the user to input information to be verified, such as a password.

[0165] like Figure 19 The diagram shows a graphical interface for password input and verification on a display screen in one embodiment of the present disclosure.

[0166] exist Figure 19In this embodiment, the display screen 1900 is adapted to display a first human-computer interaction interface 1910 for inputting information to be verified. Specifically, the first human-computer interaction interface 1910 may include a password input field 1911 and a virtual keyboard 1912 for inputting a password. When the display screen 1900 is implemented as a touch screen, the user can perform touch operations on the virtual keyboard 1912 to form input in the password input field. In this embodiment, the virtual keyboard 1912 may be implemented as a numeric keypad. Alternatively, in other embodiments, the virtual keyboard 1912 may also be implemented as an 87-key keyboard or a 104-key full-key keyboard.

[0167] In some embodiments, the action of the display screen 1900 displaying the first human-computer interaction interface 1910 can be triggered by specific conditions. As an example, the specific condition can be set to, for example, the actuation of the start / stop switch 1852. Specifically, when the user presses the start / stop switch 1852, the display screen 1900 can be triggered to display the first human-computer interaction interface 1910.

[0168] Furthermore, the unlock detection unit 422 is adapted to display a second human-machine interface 1920 on the display screen 1900 in response to the successful verification of the information to be verified. Exemplarily, the second human-machine interface 1920 displays a first graphical control 1921 (i.e., a first icon) for the walking motor and a second graphical control 1922 (i.e., a second icon) for the working motor, which are independent of each other, as activation switches. The user can choose to click the first graphical control 1921 to activate the walking motor and click the second graphical control 1922 to activate the working motor.

[0169] According to this embodiment, the activation process of the walking motor and / or the working motor can also be implemented as follows: the start / stop switch 1852 is actuated → the display screen shows the first human-machine interface 1910 for inputting verification information → the input verification information is passed, and the device is unlocked → the carrying device is occupied and the activation switch accepts the activation operation → the walking motor and / or the working motor is activated. Then, the walking function and / or the working function can be used.

[0170] In some embodiments, the start / stop switch 1852 can be integrated with certain types of input units 421, enabling simultaneous unlocking and starting when operated. For example, the start / stop switch 1852 can be implemented as a button, with a fingerprint / palmprint sensor on the pressing surface, allowing the user to complete both unlocking and starting actions simultaneously when pressing the start / stop switch. Optionally, the start / stop switch 1852 can also form a space for an indicator light (not shown), and its surface can have a light-emitting portion made of a light-transmitting material for the indicator light path to output. The indicator light can have different colors and can be electrically connected to a controller system, such as a VCU or a controller with an integrated VCU, so that it can be illuminated according to different operating states.

[0171] Please see Figures 20 to 25 The diagram shows a circuit module structure of an unlock detection unit that works with different types of input units in the embodiments of this disclosure.

[0172] like Figure 20 The diagram shown illustrates the circuit module structure of the unlock detection unit corresponding to the password input in one embodiment of this disclosure.

[0173] In this embodiment, the unlock detection unit 422a includes an unlock processor 4221a, which can be implemented as a microcontroller unit (MCU) chip. As an example, multiple communication interfaces of the unlock processor 4221a are respectively connected to the carrier device sensor 1851, the start / stop switch 1852, the keyboard 421a, the activation switch 1853, and the controller system 2090 (e.g., controller systems 290, 390, 490). Figures 10 to 17 The unlocking processor 4221a may be connected to at least one controller of any controller system. The unlocking processor 4221a may also include a power supply interface electrically connected to the battery management system.

[0174] The unlocking processor 4221a may include a memory 42211a, which may be implemented as random access memory (RAM), flash memory, read-only memory (ROM), cache, or other storage media. As an example, the memory 42211a may store preset unlocking information 422111a for matching with the information to be verified, and verification is confirmed upon matching. Taking a password as the input information to be verified, in a simple decryption algorithm, the preset unlocking information 422111a may be a preset password; a comparison is made between the input password and the preset password to determine if they are the same, thus determining whether a match has occurred. Alternatively, the preset unlocking information 422111a may also be preset encoded information (such as a hash value) obtained by using a preset encoding algorithm (e.g., hash or other algorithms) on the preset password. The unlocking processor 4221a may also call the preset encoding algorithm to encode the input password to generate current encoded information, which is then compared with the preset encoded information to obtain the verification result. Alternatively, a preset encryption algorithm can be used to generate a preset encrypted encoding information (such as a password hash value). The input password can be encoded and encrypted in the same way to obtain the current encrypted encoding information, which is then compared with the preset encrypted encoding information to obtain the verification result. In addition to the above examples, other key algorithms can also be combined, and the examples are not limited to those mentioned above.

[0175] As an example, the unlocking processor 4221a may also include a data manager 42212a for password management, such as adding or deleting passwords.

[0176] It is understood that other forms of information to be verified, such as fingerprint / palmprint information, facial information, retinal information, voiceprint information, and information transmitted in NFC, RFID, Bluetooth, and APP, can also be verified by matching with the preset unlock information 422111a. The matching includes, but is not limited to, comparison, encoding, and / or encrypted comparison.

[0177] In some embodiments, the unlocking component and / or control component may pre-store multiple sets of unlocking relationships. Each set of unlocking relationships includes: preset unlocking information for verifying the information to be verified and its corresponding usage permissions. Each usage permission is one of a combination of permissions to prohibit or allow activation of the travel motor and / or prohibit or allow activation of the working motor. For example, the first preset unlocking information corresponds to permission 1: prohibiting activation of both the travel motor and the working motor; the second preset unlocking information corresponds to usage permission 2: allowing activation of both the working motor and the travel motor; the third preset unlocking information corresponds to usage permission 3: allowing activation of the travel motor but prohibiting activation of the working motor, etc. When the travel motor includes multiple travel motors such as left and right, or when the working motor includes multiple cutter motors such as left, right, or more, the usage permissions can be further subdivided into a corresponding number of permissions according to different arrangements and combinations of these motors.

[0178] In some embodiments, the usage permission information corresponding to each preset unlock information can be stored in the storage unit of the unlock detection unit or in the storage unit of at least one controller, so as to more flexibly adapt to the needs of different scenarios.

[0179] In some embodiments, when multiple usage permissions are established, a second human-machine interface with different permissions can be provided based on the different usage permission information. For example, in the second human-machine interface corresponding to the permission of "allowing activation of the walking motor but prohibiting activation of the working motor", the first graphical control corresponding to activating the walking motor can be operated, and the second graphical control corresponding to activating the working motor can be restricted from operation or hidden.

[0180] According to the above embodiments, the required usage permissions can be unlocked by inputting verification information under different input methods. In a family scenario, if the father and mother are not at home, and only the daughter is home, and there is a sudden heavy rain or other severe weather, the father can remotely communicate with the family's ride-on lawnmower via a mobile app to unlock it by inputting usage information corresponding to the walking function but disabling the mowing function. Further exemplarily, after unlocking, the display screen on the ride-on lawnmower can show a second human-machine interface corresponding to this usage permission, for example, only displaying the first graphical control for activating the walking motor. The father can also instruct his daughter via telephone, text, voice, or video communication to drive the ride-on lawnmower back to the storage room or garage. Because the usage permission including the mowing function is not unlocked, the daughter is prevented from operating the mower, avoiding a certain degree of danger.

[0181] like Figure 21 The diagram shows a schematic of the circuit module structure of an unlocking detection unit corresponding to fingerprint / palmprint input in one embodiment of this disclosure.

[0182] In this embodiment, the unlock detection unit 422b includes an unlock processor 4221b, which can be implemented as a microcontroller unit (MCU). The MCU provides multiple communication interfaces, respectively communicating with the carrier device sensor 1851, the start / stop switch 1852, the input unit 421, the activation switch 1853, and the controller system 2090 (e.g., controller systems 290, 390, 490). Figures 10 to 17 The unlock processor 4221b is connected to at least one controller of any controller system. The unlock processor 4221b may also include a power supply interface electrically connected to the battery management system. As an example, the unlock processor 4221b may include a memory 42211b and a data manager 42212b for managing finger / palmprint data. In this embodiment, the input unit 421 is implemented as a finger / palmprint sensor 421b, communicatively connected to the unlock processor 4221b.

[0183] like Figure 22 The diagram shown illustrates the circuit module structure of an unlock detection unit corresponding to facial information or retinal information input in one embodiment of this disclosure.

[0184] In this embodiment, the unlock detection unit 422c includes an unlock processor 4221c, which can be implemented as a microcontroller unit (MCU). The MCU provides multiple communication interfaces, respectively communicating with the carrier device sensor 1851, the start / stop switch 1852, the input unit 421, the activation switch 1853, and the controller system 2090 (e.g., controller systems 290, 390, 490). Figures 10 to 17The unlocking processor 4221b is connected to at least one controller of any controller system. The unlocking processor 4221b may also include a power supply interface electrically connected to the battery management system. In this embodiment, the input unit 421 is implemented as an image acquisition device 421c, communicatively connected to the unlocking processor 4221c.

[0185] As an example, the unlocking processor 4221c may include a memory 42211c and a data manager 42212c for managing face or retinal data.

[0186] like Figure 23 The diagram shown illustrates the circuit module structure of the unlock detection unit corresponding to the recording input in one embodiment of this disclosure.

[0187] In this embodiment, the unlock detection unit 422d includes an unlock processor 4221d, which can be implemented as a microcontroller unit (MCU). The MCU provides multiple communication interfaces, respectively communicating with the carrier device sensor 1851, the start / stop switch 1852, the input unit 421, the activation switch 1853, and the controller system 2090 (e.g., controller systems 290, 390, 490). Figures 10 to 17 The unlocking processor 4221d can be connected to at least one controller of any controller system. The unlocking processor 4221d may also include a power supply interface electrically connected to the battery management system. In this embodiment, the input unit 421 can be implemented as a voice acquisition device 421d, communicatively connected to the unlocking processor 4221d.

[0188] As an example, the unlocking processor 4221d may include a memory 42211d and a data manager 42212d for managing voiceprint data.

[0189] like Figure 24 The diagram shows a schematic representation of the circuit module structure of an unlocking detection unit corresponding to a wireless signal input in one embodiment of this disclosure.

[0190] In this embodiment, the unlock detection unit 422e includes an unlock processor 4221e, which can be implemented as a microcontroller unit (MCU). The MCU provides multiple communication interfaces, respectively communicating with the carrier sensor 1851, the start / stop switch 1852, the input unit 421, the activation switch 1853, and the controller system 2090 (e.g., controller systems 290, 390, 490). Figures 10 to 17 The input unit 421 is connected to at least one controller of any controller system. The unlocking processor 4221e may also include a power supply interface electrically connected to the battery management system. In this embodiment, the input unit 421 is implemented as a wireless communication device 421e, including at least one of, for example, NFC, RFID, mobile communication, and Bluetooth communication circuits.

[0191] As an example, the unlock processor 4221e may include a protocol stack 42211e corresponding to the communication protocol of the wireless communication device 421e. A data manager 42212e is also included for managing preset unlock information (such as electronic keys). Since the unlock processor needs to communicate and respond to external systems, for data security reasons, the unlock processor 4221e may optionally include a secure access controller 42213e.

[0192] Verification of information may fail due to environmental factors. For example, in password verification, errors or lack of familiarity with the process may lead to incorrect input of numbers or symbols. In fingerprint / palmprint recognition, obstructions, incomplete or unclear fingerprint lines, or other factors can cause errors. In voiceprint verification, changes in the user's voice due to illness or other reasons can result in errors. When using NFC, RFID, Bluetooth, or mobile communication methods, verification may fail due to communication failures or input unit malfunctions.

[0193] It should be noted that, in another embodiment, when the unlock detection unit is implemented in at least one controller, the controller's memory may store preset unlock information. The controller can determine whether the verification is successful based on the matching of the information to be verified input by the input unit with the preset unlock information, and set the unlock state based on the unlock signal generated when the verification is successful. Optionally, the memory may also store usage permission information corresponding to each preset unlock information, for setting the unlock state of the corresponding usage permission.

[0194] Therefore, such as Figure 25 The diagram illustrates a verification process for information to be verified in one embodiment of this disclosure.

[0195] The verification process includes:

[0196] Step S2501: Determine whether the received information to be verified has been successfully verified.

[0197] First, determine whether you have received a correctly formatted and identifiable password, biometric information (face, fingerprint / palm print, retinal information, etc.), or wireless communication signals (NFC, RFID, Bluetooth, mobile communication network signals, etc.) for verification.

[0198] Secondly, a verification procedure is used to verify the information to be verified.

[0199] If yes, proceed to step S2502; if no, proceed to step S2504.

[0200] Step S2502: Successful unlocking confirmed.

[0201] Step S2503: Start the outdoor work vehicle.

[0202] Optionally, during this step, the user can press the start / stop switch to start the outdoor work vehicle. Afterwards, the travel motor and / or work motor can be activated, depending on user access permissions or not.

[0203] Step S2504: Determine that unlocking has failed.

[0204] Step S2505: Determine whether the number of unlocking failures has reached the preset threshold N.

[0205] Specifically, biometric information may change over time / biological state, leading to verification failure. For example, typos or prolonged disuse may result in incorrect numbers or symbols when entering a password. Similarly, hoarseness due to illness or other factors can alter a user's voiceprint, causing errors in voiceprint recognition. Of course, this example could utilize a self-learning voiceprint recognition system that continuously updates itself over time, adapting to changes in the user's voice. Furthermore, dirt or water stains on the hands can hinder recognition, leading to errors in fingerprint / palmprint recognition. Therefore, multiple verifications can help improve the verification's error tolerance. As an example, N can be 3, 4, 5, or larger, and can be set according to actual needs.

[0206] Furthermore, considering the possibility of biometric information being forged, such as using user photos to forge facial information, using fingerprint / palmprint rubber to forge finger / palmprint information, or using voice simulators to forge voiceprint information, the outdoor work vehicle can also be equipped with corresponding devices for implementing liveness detection technology. For example, the user can be prompted to perform specified actions through audio / video acquisition / playback devices, such as performing head / face movements, reading specified words or sentences, to prevent at least some forged biometric information from being verified.

[0207] In some embodiments, for reliability reasons, when employing any combination of the above unlocking functions, password unlocking can be used as a final backup solution. If the password is forgotten, remedies such as phone or internet access can also be provided for password retrieval.

[0208] If yes, proceed to step S2506; otherwise, return to step S2501.

[0209] Step S2506: Keep the outdoor work vehicle locked.

[0210] That is, the user is prohibited from using the walking and working functions of the outdoor work vehicle. Optionally, a warning or prompt message can be generated and sent to the designated user's terminal via a mobile network or wired internet network to indicate that the outdoor work vehicle has not been unlocked, facilitating a quick response from the user to take the next step.

[0211] like Figure 26 The diagram shows a flowchart of a control method according to an embodiment of this disclosure. This control method can be applied to the control system of outdoor work vehicles in previous embodiments.

[0212] In this embodiment, the control method includes:

[0213] Step S2601: When the control system is in the off state, the control component is activated in response to the start / stop switch of the outdoor work vehicle, and obtains the user-input verification information through the unlocking component.

[0214] Step S2602: In response to the successful verification of the information to be verified, the control component unlocks and starts the control system so that the motor switch command unit can be activated.

[0215] In some embodiments, the information to be verified can be verified by the unlocking component or output by the unlocking component to the control component for verification.

[0216] Step S2603: The control component responds to the acquired signal satisfying a preset condition group by activating the motor switch command unit to activate the walking motor and / or the working motor.

[0217] The preset condition group has been described in previous embodiments, including, for example, the verification of the information to be verified being passed, the start / stop switch being actuated, the carrier device sensor detecting that the carrier device is occupied, and the activation switch being activated.

[0218] Optionally (indicated by dashed lines), the method may further include:

[0219] Step S2604: When the control system is in the start state, the control component responds to the start / stop switch being actuated, sets the control system to the off state, and the control component is in a locked state pending unlocking.

[0220] That is, when the outdoor work vehicle is turned off by the start / stop switch, the walking motor and the working motor are locked and can only be activated and used after being unlocked again, which effectively improves safety.

[0221] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
