[0045] The present application will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0046] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. For example, the terms "first," "second," and "third" are used solely to facilitate the description of relevant parameters involved in this application and have no special meaning. Therefore, they should not be construed as limitations on this application.

[0047] Example 1

[0048] In response to the shortcomings of the prior art, the purpose of this application is to provide a gear control method for an electric work vehicle, wherein the electric work vehicle is a lawn mower, and the control method can achieve the effect of accurately, in real time, and intelligently adjusting the gear of the lawn mower remotely. The gear is the mowing gear of the lawn mower. Different gears can make the mowing power system of the lawn mower output according to different parameters such as power and speed to cope with different grass conditions. For example, when the lawn mower is traveling in an area with denser grass, the power output needs to be increased, and when it is traveling in an area with sparser grass, the power output of the mowing system or the cutter can be adjusted by adjusting the gear of the lawn mower.

[0049] As shown in Figure 1, the control method includes the following steps: establishing a communication connection between the lawn mower and a mobile electronic device; then determining whether the last operating instruction to adjust the lawn mower's working gear came from the lawn mower or the mobile electronic device. The determination includes: if the operating instruction came from the lawn mower, the lawn mower sends first information including the adjusted working gear to the mobile electronic device, and the mobile electronic device records and outputs the first information; and if the operating instruction came from the mobile electronic device, the mobile electronic device sends second information including the operating instruction to the lawn mower, and the lawn mower adjusts the working gear based on the received second information.

[0050] Preferably, the lawn mower is configured such that, after the step of establishing a communication connection between the lawn mower and the mobile electronic device, the lawn mower transmits a third message to the mobile electronic device, including a suggestion for adjusting the working gear. Specifically, after the third message is transmitted to the mobile electronic device, the user, who can operate the mobile electronic device, confirms whether to execute the third message. The suggestion for adjusting the working gear includes a suggestion for adjusting the working gear and a query as to whether to adjust the working gear. Examples of suggestions include: a suggestion for adjusting the gear to a higher gear under high load conditions; a suggestion for adjusting the gear to a lower gear under low load conditions. The lawn mower may analyze the operating conditions, including monitored motor or cutter operating parameters or grass density, and make such suggestions after comparing the lawn mower's current gear with the gear adjustment instruction issued by the mobile electronic device. Specifically, when the operating instruction comes from the mobile electronic device, the lawn mower transmits the third message to the mobile electronic device based on the real-time load. The user can receive the suggestion information through the lawn mower, particularly through a mobile electronic device, and decide whether to adjust the gear accordingly. Adjusting the gear can involve operating the lawn mower's gear adjustment mechanism or performing gear adjustment operations on the mobile electronic device. Gear adjustment operations are not limited to manual operation and can also include voice, head movement, or footsteps. Of course, the user can also set the lawn mower to automatically accept the suggestion from the third information without the user having to make any judgment or operation.

[0051] Preferably, the operating gears include multiple fixed gears corresponding to different speed values. Each fixed gear corresponds to a threshold range of the mower's load. For example, the fixed gears may be first, second, and third (of course, two, four, or more gears may be provided). The load corresponding to first, second, and third gears increases (or decreases) in sequence. Each gear corresponds to a different mowing output intensity (e.g., a different speed) and, therefore, a different load condition. The load condition is influenced by the operating conditions, primarily the grass conditions. The load condition can be determined manually or by monitoring motor or cutter operating parameters or grass density. Each fixed gear corresponds to a threshold range of the mower's load condition, such as a range of changes in the speed of the cutter or mowing motor, or a range of changes in the voltage or current of the mowing motor. The mower includes a cutting element, and the mower executes the fixed gear command to adjust the cutting element's speed to the speed value of the corresponding gear, thereby adjusting the output requirement corresponding to the executed fixed gear.

[0052] Preferably, the operating gear also includes an automatic gear corresponding to a variable speed value. Automatic gear corresponds to a non-fixed speed value for the cutting element. After the lawn mower executes the automatic gear, the lawn mower adjusts the speed of the cutting element based on the real-time load, such as automatically increasing the speed at higher loads and automatically decreasing the speed at lower loads. Automatic gear adjusts the gear of the lawn mower, eliminating the need for the stepped speed regulation used in fixed gears, where the speed corresponding to each gear is a set fixed value. Instead, it uses automatic, stepless speed regulation, enabling precise and automated lawn mower control, improving mowing efficiency and reducing energy consumption.

[0053] Preferably, during the operation of the lawn mower, the load condition of the lawn mower can be obtained in the following manner: collecting the operating parameters of the power source that drives the cutting element, and then identifying the real-time load of the lawn mower based on the operating parameters. In this embodiment, the cutting element is a cutter, and the power source is a motor that drives the cutter. The operating parameters include one or more parameters including speed, PWM (pulse width modulation) duty cycle, voltage, current and continuous flow time. The principle of judging the load size and change by the motor operating parameters belongs to the prior art and will not be repeated here. By identifying the real-time load of the lawn mower based on the operating parameters, real-time and automated load monitoring can be achieved, which solves the problem of errors and inaccuracies in the gear adjustment of the lawn mower caused by errors in human judgment of the load.

[0054] Preferably, the lawn mower includes both fixed and automatic gear settings. For example, there are four gears: first, second, third, and automatic. When the user chooses first, second, or third gear, stepped speed regulation is used, that is, the speed value corresponding to each gear is a set fixed value, while automatic gear uses automatic stepless speed regulation. The aforementioned first, second, and third gear stepped speed regulation sets a fixed speed for the motor. The higher the speed, the greater the energy loss, and the lower the speed, the lower the energy loss. For ease of operation, users usually choose to directly use third gear to cope with all load conditions, which results in a certain degree of energy waste when the grass is sparse and the load is low. Therefore, automatic gear combined with load-adaptive adjustment of the operating parameters of the power source can solve the above problem: the lawn mower's control unit identifies the load condition by collecting relevant parameters such as the speed, PWM duty cycle, voltage, current, and freewheeling time of the mowing motor during operation, and automatically adjusts the speed of the power source according to the load. Of course, the control unit can also collect real-time parameters from other units or circuits of the lawn mower to comprehensively judge the load conditions, such as the current and voltage changes at the power input end of the electric work vehicle. This belongs to the same principle and will not be repeated here.

[0055] Preferably, the mobile electronic device includes a mobile phone, a handheld remote control device, etc. The step of the mobile electronic device recording and outputting the first information specifically includes: the mobile phone storing the first information, displaying the first information on the display screen of the mobile phone, and / or playing the first information through the speaker or earphones of the mobile phone. The first information is the current working gear information of the lawn mower after the working gear is adjusted. The mobile phone receives and records the working gear information and conveys it to the user through the mobile phone. The user receives the information by observing the mobile phone display screen, listening to the prompt sound emitted by the mobile phone, etc. The mobile phone can realize information interaction with the lawn mower through the APP software installed thereon. Conversely, when the user issues an operation instruction by operating the mobile phone or APP, that is, when the operation instruction to adjust the working gear comes from the mobile phone, the mobile phone sends the second information including the operation instruction to the lawn mower, and the lawn mower adjusts its working gear according to the received second information.

[0056] The widespread use of mobile phones, especially smartphones, allows users to remotely control the operating mode of a lawn mower, including gear positions, and allows for customized automatic gear adjustment, making lawn mower use safer and smarter. Mobile electronic devices include not only mobile phones but also portable or wearable electronic devices such as laptops, smart wristbands, and electronic watches. Mobile electronic devices, including mobile phones, can also be used to start or stop a lawn mower, adjust the number of fixed gears, the load threshold range and output speed corresponding to each fixed gear, and select between fixed and automatic gears.

[0057] Preferably, the mobile electronic device can connect to the internet and upload the first and second information to a cloud server. The cloud server can be provided by the brand, sales, manufacturer, or service provider of the lawn mower. If the mobile electronic device is a mobile phone, the mobile phone app will record the gear adjustment information performed and the gear information received from the lawn mower, and then upload it to the cloud using the MQTT protocol, the UDP protocol, or the 4G TCP / IP protocol. By integrating the data on the cloud, a usage record for each gear is generated, and then optimization processing is performed based on the usage of each gear, which can be used to further enhance the user experience.

[0058] Preferably, to facilitate intelligent management of the lawn mower and prevent theft or unsafe use of the lawn mower, after the lawn mower establishes a communication connection with the mobile electronic device, the following steps are further included: the mobile electronic device sends a request to the lawn mower to obtain the device ID; then, upon receiving the request, the lawn mower sends the device ID to the mobile electronic device; then, the mobile electronic device connects to the Internet and queries the cloud server to determine whether the device ID has permission to use. If the mobile electronic device has permission to use, the lawn mower is allowed to execute the operating instructions from the mobile electronic device, and the mobile electronic device can upload the first and second information to the cloud server; if the mobile electronic device does not have permission to use, the lawn mower is prohibited from executing the operating instructions from the mobile electronic device.

[0059] Preferably, the cloud server pre-stores a user ID corresponding to the device ID, wherein when the mobile electronic device connects to the Internet and queries the cloud server whether the device ID has permission to use, it specifically includes: whether it has permission to use is based on whether the mobile electronic device has the user ID corresponding to the device ID. When querying the cloud server whether the device ID has permission to use, it is to query whether the device ID corresponds to the user ID carried by the mobile electronic device. If the user ID corresponding to the device ID recorded by the cloud server does not match the user ID that currently issues the request, or the mobile electronic device does not have a valid user ID, it is considered that there is no permission to use.

[0060] In this embodiment, each lawn mower has a unique device ID, which can be composed of components such as the production date, machine model, and machine serial number. The device ID is automatically generated when the riding lawn mower is manufactured. After the device ID is generated by the host computer, the number is sent to the burning tool. The burning tool then transmits the device ID to the lawn mower via a serial port or other means. Finally, the lawn mower stores the received device ID in its internal Flash storage area. When a user purchases a lawn mower, the seller can create a user account for the user. The account number includes: user ID, purchase date, and existing device IDs. A user ID can correspond to multiple device IDs. For each product purchased, the user can add the corresponding device ID to the user management account.

[0061] Preferably, the communication connection includes a WIFI connection, a Bluetooth connection and a data cable connection, and the lawn mower is a riding lawn mower.

[0062] The implementation scenario of wireless connection and management between a riding lawn mower and a mobile phone is as follows: the riding lawn mower is started, the Bluetooth module is powered on, and the mobile phone Bluetooth is connected to the Bluetooth of the riding lawn mower; the mobile phone sends a request to obtain the device ID to the riding lawn mower, and after receiving the request, the riding lawn mower sends the stored device ID to the mobile phone; the mobile phone queries the user account from the cloud server backend through the Internet to check whether the device ID is the device ID owned by the user. If so, the mobile phone is allowed to send command information including adjusting the working gear to the riding lawn mower; if not, the mobile phone is prohibited from remotely adjusting the gear of the riding lawn mower. In addition to wireless connection through the Bluetooth module, wireless connection can also be achieved through the WIFI module. When the riding lawn mower is started, the built-in WIFI module is powered on, the mobile phone and the WIFI module are connected to the same wireless router, and the WIFI connection is achieved through the wireless router.

[0063] The implementation scenario for remotely controlling the gear position of a riding lawn mower is as follows: The riding lawn mower stores a device ID, and the mobile app needs to bind the user ID. After establishing a wireless connection with the riding lawn mower, the phone queries the device ID and establishes a binding relationship between the device ID and the user ID. The riding lawn mower processes operating parameters such as speed, PWM duty cycle, voltage, current, and freewheeling time to determine the load condition (high load / low load). After establishing a connection with the mobile phone, the current load information and gear position information are sent to the mobile phone. After adjusting the gear position, the mobile phone transmits the gear position value to the riding lawn mower, which then adjusts the gear position based on the received gear position value. Finally, the device that performs the gear adjustment operation has control of the riding lawn mower, and the gear position value of the other device must be synchronized with the gear position value of the control terminal. Based on the real-time load information of the riding lawn mower, a user usage record of the riding lawn mower can be generated. By obtaining the device ID, user ID, and real-time load information, remote gear control of the riding lawn mower can be achieved.

[0064] The implementation scenario for remote gear control and information synchronization between a riding lawn mower and a mobile phone is as follows: the mobile phone establishes a wireless connection with the riding lawn mower; the device that last performed the gear adjustment operation is determined, and this device is set as the master and the other device is set as the slave; when the master is the mobile phone, the mobile phone sends an operating instruction to adjust the working gear to the riding lawn mower, and the gear of the riding lawn mower changes according to the instruction, including the gear indicator light, speed, duty cycle, etc. During this period, the riding lawn mower sends the load situation to the mobile phone and makes suggestions for adjusting the working gear (for example: the current working condition is high load, should the gear be increased?). When the riding lawn mower is the master, the riding lawn mower sends the current gear value to the mobile phone, and the gear value on the mobile phone app interface changes, achieving gear synchronization between the two devices.

[0065] This application allows users to remotely control the lawn mower by establishing a communication connection between the lawn mower and a mobile electronic device; the mobile electronic device can update, record and output the gear status of the lawn mower in real time, achieving the effect of remote monitoring and intelligent management; the lawn mower can automatically adjust the gear, which can not only adjust the cutter output according to the grass conditions to improve the battery life of the entire machine, but also allow users to further get rid of the gear adjustment operation, which is very safe and convenient.

[0066] Example 2

[0067] Please refer to Figure 2. The present application also provides a lawn mower, including a communication module and a control module. The communication module is used for the lawn mower to establish a communication connection with a mobile electronic device; the control module is used to determine whether the last operation instruction for adjusting the working gear of the lawn mower came from the lawn mower or the mobile electronic device; wherein, when the operation instruction comes from the lawn mower, the lawn mower sends a first information including the adjusted working gear to the mobile electronic device, and the mobile electronic device records and outputs the first information externally; when the operation instruction comes from the mobile electronic device, the mobile electronic device sends a second information including the operation instruction to the lawn mower, and the lawn mower adjusts the working gear according to the received second information. For the lawn mower provided by the present application, the above-mentioned module division is only an exemplary statement, wherein the communication module and the control module can also be integrated into one module to realize the communication and control functions.

[0068] This application allows users to remotely control the lawn mower by establishing a communication connection between the lawn mower and a mobile electronic device; the mobile electronic device can update, record and output the gear status of the lawn mower in real time, achieving the effect of remote monitoring and intelligent management; the lawn mower can automatically adjust the gear, which can not only adjust the cutter output according to the grass conditions to improve the battery life of the entire machine, but also allow users to further get rid of the gear adjustment operation, which is very safe and convenient.

[0069] Example 3

[0070] The present application also provides a lawn mower for implementing the control method described in Example 1, comprising a memory and a processor; the memory stores computer instructions; the processor is connected to the memory, and is used to obtain and execute computer instructions from the memory to implement the control method.

[0071] This application allows users to remotely control the lawn mower by establishing a communication connection between the lawn mower and a mobile electronic device; the mobile electronic device can update, record and output the gear status of the lawn mower in real time, achieving the effect of remote monitoring and intelligent management; the lawn mower can automatically adjust the gear, which can not only adjust the cutter output according to the grass conditions to improve the battery life of the entire machine, but also allow users to further get rid of the gear adjustment operation, which is very safe and convenient.

The aforementioned storage medium includes various media that can store program codes, such as a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk.

[0076] Example 5

[0077] As shown in Figures 3-4, the present application also provides an electric working vehicle system, which includes an electric working vehicle and a mobile electronic device, wherein the mobile electronic device can be a mobile terminal such as a mobile phone or a remote controller. The electric working vehicle includes a control system; the control system includes an operation status information acquisition unit, an information storage unit, an information transmission unit, and an operation control unit; the operation status information acquisition unit is used to obtain the operation status information of the electric working vehicle; the information storage unit stores the acquired operation status information data; the information transmission unit is used to transmit the acquired operation status information data to the mobile electronic device via wireless communication, and receive operation instruction information for the electric working vehicle from the mobile electronic device; the operation control unit is used to control the actuator of the electric working vehicle to perform corresponding operations according to the received operation instruction information.

[0078] The following electric work vehicle uses a riding lawn mower as an example. This riding lawn mower has both walking and mowing functions, and its actuators include a travel motor and / or a work motor. Of course, this electric work vehicle can also be used for outdoor work, such as snowplows, seed drills, and rice transplanters. In this embodiment, the work motor is a cutting motor, which drives the cutting blade.

[0079] The following description of the operating command information for an electric work vehicle uses, as an example, command information for adjusting the cutting motor gear position of a riding lawn mower, which has multiple fixed gears, such as first, second, and third, as well as an automatic gear position (Auto). Of course, the operating command information can also include information for adjusting other operating states of the riding lawn mower, such as command information for adjusting travel speed, cutting deck height, grass collection and / or discharge, drive wheel height adjustment, straight line calibration, battery pack discharge management, braking and / or parking, etc.

[0080] In the fixed gear mode, the user monitors the operating status information of the riding lawn mower in real time, and the user issues operating instruction information for adjusting the gear of the riding lawn mower's operating motor through the operating interface on the mobile electronic device or the operating component on the riding lawn mower based on the operating status information.

[0081] In Auto mode, the mobile electronic device and / or riding lawn mower automatically interprets the received operating status information and generates operating instructions that match the operating status information. In this mode, the user does not need to monitor the operating status of the riding lawn mower by staring at the screen of the mobile electronic device in real time.

[0082] In the electric work vehicle and the mobile app, the work motor is set to 1st gear, 2nd gear, 3rd gear, and Auto gear. Users can adjust the gear through the app according to the density of grass, instead of operating on the work vehicle, or directly select Auto gear and let the app adapt to the load according to the real-time load conditions received. In another case, the electric work vehicle does not have a load adaptation function or an Auto gear mode. In this case, the load adaptation function of the work vehicle can still be achieved by inputting a program that automatically adjusts the gear according to the workload on the mobile app. The mobile app sends an adjustment instruction information based on the different load information received to switch the gear of the work motor.

[0083] Operating status information includes operating parameters and / or hardware information of the riding lawn mower, such as the gear position of the cutting motor, real-time load information, driving speed information, battery charge information, operating hours, vehicle fault information, brand information, ID information, and external environmental information. In manual mode, the user uses this information to determine whether to adjust the current operating status of the riding lawn mower. In auto mode, the mobile electronic device or the riding lawn mower automatically determines whether to adjust the current operating status of the riding lawn mower based on this information.

[0084] The operating status information can be obtained through sensors installed on the riding lawn mower, or by monitoring the operating parameters of the cutting motor and / or the travel motor. For example, the load condition of the cutting motor can be determined by processing data such as the speed, PWM duty cycle, voltage, current, and freewheeling time during operation.

[0085] The mobile electronic device includes a first communication module, and the electric work vehicle includes a second communication module, and the second communication module is connected to the first communication module via wireless communication; after the user sends an operation instruction information for adjusting the gear of the riding lawn mower through the mobile electronic device, the gear value is transmitted to the riding lawn mower via wireless communication, and the riding lawn mower adjusts the gear according to the received gear value; after the user adjusts the gear through the gear adjustment operation component on the riding lawn mower, the riding lawn mower synchronizes the adjusted gear information to the mobile electronic device via wireless communication.

[0086] The mobile electronic device has a built-in first application program for interacting with the riding lawn mower, and the user triggers operation information instructions for the riding lawn mower through an icon on a graphical interface corresponding to the first application program; of course, the mobile electronic device also has a display interface to display operating status information of the riding lawn mower, user usage records, adjusted gear information and / or external environmental information, such as grass density information, grass height information, weather information, etc.

[0087] Optionally, the mobile electronic device includes an interface for receiving user operation information, through which the user issues operational information instructions for the electric work vehicle. The interface may include electronic / physical buttons, a handle, a human-computer interface, and a voice recognition component. After the lawn mower wirelessly transmits operating parameter information to the mobile electronic device, the mobile electronic device issues a message prompting the user to adjust the gear position, including a recommended gear position, based on the operating parameter information. The mobile electronic device may prompt the user via a display interface or voice prompt. The user then selects whether to change the gear position through the interface based on the prompt.

[0088] The riding lawn mower is equipped with an operating component, through which the user controls the operating gear of the riding lawn mower's mowing motor. When the riding lawn mower and the mobile electronic device are in communication, the mobile electronic device obtains real-time load information and gear value. Specifically, data information from the riding lawn mower can be synchronized with the mobile electronic device at regular intervals, and changed operating status information can also be automatically synchronized to the mobile electronic device when the riding lawn mower's operating component is triggered.

[0089] Optionally, the method for the control unit to automatically match the working gear according to the load includes: pre-storing the correspondence between the motor's operating parameters and the load and the upper and lower boundary thresholds of the load in the memory of the control unit; collecting the motor's operating parameters, the operating parameters including at least one of duty cycle, speed, current and power; identifying the motor's load based on the motor's operating parameters; comparing the correspondence between the motor's operating parameters and the load, if the operating parameters are greater than the upper boundary threshold of the load, increasing the motor's performance parameters, if the operating parameters are less than the lower boundary threshold of the load, reducing the motor's performance parameters, the motor's performance parameters including power, speed, current and torque.

[0090] Optionally, a control unit module that automatically matches the working gear according to the load can be set on the riding lawn mower or on a mobile electronic device. The control unit module calculates and / or simulates the working gear and / or cutting motor speed that matches the load based on the real-time load. When the control unit module is located on the mobile electronic device, the mobile electronic device parses the received riding lawn mower operating status information to generate a matching gear value and / or motor speed value, and transmits the operating instruction information containing the gear value and / or motor speed value to the riding lawn mower's operating control unit via wireless communication, thereby achieving low-load, low-power gear output and high-load, high-power gear output, and more accurate control and output adjustment of the working motor, thereby improving the endurance of the riding lawn mower.

[0091] Optionally, a single mobile device ID can be associated with multiple riding lawn mower IDs at the same time. A riding lawn mower ID can only be associated with one user ID at a time. After establishing a wireless connection between the mobile device and the riding lawn mower, the app can query the riding lawn mower ID to determine if it corresponds to a user ID. Specifically, each riding lawn mower has a unique machine ID, which can consist of components such as the production date, machine model, and machine serial number. The machine ID is automatically generated when the riding lawn mower is manufactured. After the machine ID is generated by the host computer, it is sent to a burning tool, which then transmits the machine ID to the riding lawn mower via a serial port or other means. The riding lawn mower then stores the received machine ID in its internal flash memory. When a user purchases a riding lawn mower, the seller can create a user account for the user. This account includes the user ID, purchase date, and the machine IDs owned. Each time a user purchases a product from our company, the corresponding machine ID is added to their user management account. The process of wireless connection and management between a riding lawn mower and a mobile phone is as follows: 1) The riding lawn mower is started, the Bluetooth module is powered on, and the mobile phone Bluetooth is connected to the Bluetooth of the riding lawn mower; 2) The mobile phone sends a request to the riding lawn mower to obtain the machine ID, and the riding lawn mower sends the stored machine ID to the mobile phone after receiving the request; 3) The mobile phone queries the user account from the server backend through the Internet to check whether the machine ID is the machine ID owned by the user. If so, the mobile phone is allowed to send gear adjustment instructions to the riding lawn mower; if not, the mobile phone is prohibited from remotely adjusting the gear of the riding lawn mower. In addition to wireless connection through the Bluetooth module, wireless connection can also be made through the WIFI module. When the riding lawn mower is started, the built-in WIFI module is powered on, the mobile phone APP and the WIFI module are connected to the same wireless router, and the WIFI connection is achieved through the wireless router; the rest of the steps are the same as above.

[0092] The riding lawn mower transmits operating status information of the riding lawn mower to a mobile electronic device via wireless communication, and the mobile electronic device controls the operating components of the riding lawn mower to perform corresponding operations via wireless communication. The wireless communication mentioned above refers to receiving status information and / or command information using one of the following wireless communication methods: BLE low-energy Bluetooth communication technology, WLAN wireless local area network communication technology, Zigbee wireless communication technology, UWB ultra-wideband wireless communication technology, EnOcean communication technology, Z-Wave communication technology, and NFC near-field communication technology.

[0093] As shown in Figure 7, the riding lawn mower controller has an internal current and voltage acquisition module. The MCU exchanges information with the mobile app via the communication module. The MCU processes the collected voltage, current, and PWM information to determine the corresponding load condition (which can be categorized as high, medium, or low load, and the load condition can be differentiated by gear). This information, along with the current gear, is sent to the mobile app via the communication module. The communication module also receives gear control commands from the mobile app. The riding lawn mower's gear control can be divided into two scenarios: scenario 1: the riding lawn mower performs the most recent gear control; scenario 2: the mobile app performs the most recent gear control. In scenario 1, the riding lawn mower is set as the host. The riding lawn mower sends the current gear information and load to the mobile app, and the gear displayed on the mobile app is updated to the received gear value. In scenario 2, the mobile phone is set as the host. The phone sends gear adjustment commands to the riding lawn mower, which adjusts the gear accordingly, adjusting the duty cycle and gear display accordingly. The riding lawn mower sends load and gear information to the mobile phone. If the current gear does not match the load information, the app can prompt the user to adjust the gear. Figure 8 shows the software flow chart. This solution includes four gears: 1st, 2nd, 3rd, and AUTO. When the user selects 1st, 2nd, and 3rd gears, the speed is adjusted in steps, meaning the speed for each gear is a fixed value. AUTO, on the other hand, provides automatic, stepless speed regulation.

[0094] Energy consumption in riding lawn mowers is primarily divided into two components: the rider and the mowing motor. The aforementioned 1, 2, and 3 speed control sets a fixed motor speed. Higher speeds increase energy loss, while lower speeds reduce energy loss. For ease of operation, users often choose to operate in 3rd gear to accommodate all load conditions, resulting in a certain degree of energy waste. Therefore, the AUTO gear load adaptation function was developed to address this issue. The control board collects relevant parameters such as the riding lawn mower's speed, PWM duty cycle, voltage, current, and freewheeling time during operation to identify the load and automatically adjust the speed accordingly. As shown in Figure 4, the mobile app records the gear adjustment information generated by the app and the gear information received from the control board. The information is then uploaded to the cloud using MQTT, UDP, or 4G TCP / IP. Developers then integrate this cloud data to generate a usage history for each gear and then optimize the process based on individual gear usage, further enhancing the user experience.

[0095] Optionally, the control system of the electric working vehicle can be composed of multiple controller components with different functions, or it can be an integrated controller component, which controls the travel motor, working motor and overall operating status of the working vehicle. The integrated controller component is integrated with multiple travel control units, multiple power output control units and a whole vehicle control unit. Among them, the multiple travel control units are configured to control multiple travel motors respectively, and the multiple power output control units are configured to control multiple working motors respectively. The whole vehicle control unit is configured to control the overall operating status of the multi-functional vehicle. The integrated controller component is integrated with multiple travel control units, multiple power output control units and a whole vehicle control unit, which means that the corresponding circuit components of multiple control units are at least partially integrated in at least one circuit board. For example, all circuit components of multiple control units can be integrated in one circuit board. The circuit board can be a PCB board or an aluminum substrate. The use of an aluminum substrate is conducive to heat dissipation of the integrated multiple control units.

[0096] The integrated controller assembly integrates multiple travel control units for controlling multiple travel motors, at least one power output control unit for controlling at least one working motor, and a vehicle control unit for performing vehicle status control. In this embodiment, the multi-purpose vehicle may include three power output motors, three output members, and three corresponding power output control units.

[0097] In the integrated controller assembly, the components within each control unit are tightly arranged, and the communication and power transmission lines between the multiple control units are also integrated. This significantly reduces the number of wiring harnesses and terminal blocks required, effectively lowering costs, improving the efficiency of product production, assembly, testing, and debugging, and significantly enhancing the safety and stability of the entire device.

[0098] The riding lawn mower also has a power system that supplies power to the travel motor and the working motor. The power system includes multiple battery cells. These battery cells can be selected from at least one of a first specification battery pack and a second specification battery pack. Specification differences between the first and second specification battery packs include, but are not limited to, differences in battery pack capacity, voltage, internal resistance, weight, size, energy density, cell type, charge information, and battery health status information.

[0099] In some optional embodiments, the difference between the first specification battery pack and the second specification battery pack is that the battery pack capacity is different. The capacity of the first specification battery pack is greater than the capacity of the second specification battery pack. The second specification battery pack is configured to provide power for handheld garden tools. For example, the second specification battery pack can power garden tools such as lawn mowers, pruners, hair dryers, and chainsaws. In addition, the second specification battery pack can also power torque output tools such as electric drills and electric hammers; power sawing tools such as electric circular saws, jigsaws, and reciprocating saws, or power grinding tools such as angle grinders and sanders.

[0100] In some optional embodiments, the first and second battery packs differ in the type of battery cells used. For example, the first and second battery packs may use lithium iron phosphate cells and ternary lithium cells, respectively. The multiple battery cells in the power supply system may also use nickel-cadmium cells, lead-acid cells, graphene cells, and the like.

[0101] The multiple battery cells included in the power supply system are selected from at least one of the first specification battery pack and the second specification battery pack. This allows the multi-functional vehicle to be compatible with battery packs of different specifications, meeting high-power working requirements while also being adaptable to handheld electric garden tools, making the staff's working method more flexible.

[0102] In some embodiments, the electric multi-purpose vehicle may be a gardening vehicle that can perform gardening operations such as pruning, mowing, and spraying. In some embodiments, the electric multi-purpose vehicle may be a cleaning vehicle, such as a snowplow. In some embodiments, the electric multi-purpose vehicle may be an agricultural vehicle, such as a seed drill or a tractor. In some embodiments, the electric multi-purpose vehicle may be a transport vehicle, such as a forklift. In some embodiments, the electric multi-purpose vehicle may be an off-road vehicle, such as a utility task vehicle (UTV). In some embodiments, the electric multi-purpose vehicle may be user-operated. Alternatively, it may be self-propelled / intelligent, that is, it may be able to plan navigation routes, automatically travel, avoid obstacles, etc.

[0103] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The scope of protection of the present application is not limited thereto.
