Description

Technical Field

[0001] This application relates to the field of power mode control technology, and in particular to a method, device, equipment and medium for controlling the power mode of a lawnmower. Background Technology

[0002] In the field of landscaping and lawn maintenance, lawnmowers are indispensable equipment. Traditional fuel-powered lawnmowers have long dominated the market, but with increasing environmental protection requirements and the pursuit of energy efficiency, electric lawnmowers are gradually emerging.

[0003] Early electric lawnmowers mostly operated in pure electric mode, relying solely on batteries for power. This mode had significant limitations. For example, when the battery charge was low, the lawnmower's performance would drop drastically, especially during mowing operations. Insufficient power could lead to reduced blade speed, hindering effective mowing, or even causing the vehicle to stop altogether, severely impacting work efficiency. To overcome the range anxiety of pure electric lawnmowers, range-extended electric lawnmowers were developed. However, existing range-extended electric lawnmowers have several shortcomings in power mode switching. Some models require manual operation to switch power modes, which not only increases the operator's workload but also increases the risk of human error or delayed operation, causing the vehicle to be in the wrong power mode at the wrong time. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a method, device, equipment, and medium for controlling the power mode of a lawnmower, which can automatically switch the power mode of the lawnmower according to the current state of charge value of the lawnmower, thus solving the problem of automatic power mode switching of electric lawnmowers. The specific solution is as follows:

[0005] Firstly, this application provides a method for controlling the power mode of a lawnmower, including:

[0006] The current working status of the lawnmower is monitored in real time to obtain the current working condition of the lawnmower; the current working condition is either a lawnmower working condition or a non-lawnmower working condition.

[0007] The current state of charge (SOC) value of the lawnmower under the current operating condition is determined, and a preset SOC value corresponding to the operating condition type of the current operating condition is determined; wherein, the current SOC value is used to reflect the remaining power of the lawnmower under the current operating condition, and the preset SOC value includes a lower threshold for the SOC and an upper threshold for the SOC.

[0008] If the current state of charge (SBC) value is less than the upper limit threshold, the lawnmower is controlled to operate in range-extended mode; if the current SBC value is greater than the upper limit threshold, the lawnmower is controlled to operate in pure electric mode. The range-extended mode is a mode in which the lawnmower uses a range extender to provide power to its own power-consuming devices and uses the remaining energy of the range extender to charge its own power battery. The pure electric mode is a mode in which the lawnmower uses only the power battery to provide power to its own power-consuming devices.

[0009] Optionally, the lawnmower power mode control method further includes:

[0010] When the lawnmower is detected to change from a stopped state to a started state, the lawnmower is controlled to operate in pure electric mode, and the target signal of whether the local preset device has been triggered is monitored.

[0011] If the local preset device has triggered the target signal, then proceed to the step of real-time monitoring of the current working status of the lawnmower to obtain the current working condition of the lawnmower.

[0012] Optionally, the real-time monitoring of the current working status of the lawnmower to obtain its current operating condition includes:

[0013] The current working status of the lawnmower is monitored in real time, and it is determined whether the lawnmower's blades are in the starting state and whether there is at least one drive motor with a rotation speed greater than zero in the lawnmower.

[0014] If the blades of the lawnmower are in the activated state and there is at least one drive motor with a rotational speed greater than zero in the lawnmower, then the current working condition of the lawnmower is determined to be the lawnmower's mowing condition. If the blades of the lawnmower are not in the activated state and / or there is no at least one drive motor with a rotational speed greater than zero in the lawnmower, then the current working condition of the lawnmower is determined to be the non-mowing condition.

[0015] Optionally, the step of controlling the lawnmower to operate in range-extended mode if the current state of charge value is less than the upper limit threshold, and controlling the lawnmower to operate in pure electric mode if the current state of charge value is greater than the upper limit threshold, includes:

[0016] When the current working condition of the lawnmower is non-mowing, if the current state of charge value of the lawnmower is less than the first state of charge upper limit threshold, the lawnmower is controlled to operate in range-extended mode; if the current state of charge value of the lawnmower is greater than the first state of charge upper limit threshold, the lawnmower is controlled to operate in pure electric mode.

[0017] When the current operating condition of the lawnmower is lawn mowing, if the current state of charge value of the lawnmower is less than the second state of charge upper limit threshold, the lawnmower is controlled to operate in range-extended mode; if the current state of charge value of the lawnmower is greater than the second state of charge upper limit threshold, the lawnmower is controlled to operate in pure electric mode.

[0018] Optionally, the second upper limit threshold of the state of charge is greater than the second lower limit threshold of the state of charge, the second lower limit threshold of the state of charge is greater than the first upper limit threshold of the state of charge, and the first upper limit threshold of the state of charge is greater than the first lower limit threshold of the state of charge.

[0019] Optionally, the lawnmower power mode control method further includes:

[0020] When the lawnmower switches from pure electric mode to range-extended mode, the range extender is activated and generates electricity to increase the current state of charge of the lawnmower.

[0021] When the lawnmower switches from range-extended mode to pure electric mode, the range extender stops working, and the lawnmower's power battery provides the necessary electrical energy.

[0022] Secondly, this application provides a lawnmower power mode control device, comprising:

[0023] The status monitoring module is used to monitor the current working status of the lawnmower in real time to obtain the current working condition of the lawnmower; the current working condition is either lawnmower working condition or non-lawnmower working condition.

[0024] The state of charge (SCC) determination module is used to determine the current SCC value of the lawnmower under the current working condition, and to determine a preset SCC value corresponding to the working condition type of the current working condition; wherein, the current SCC value is used to reflect the remaining power of the lawnmower under the current working condition, and the preset SCC value includes a lower limit threshold for SCC and an upper limit threshold for SCC.

[0025] The mode control module is used to control the lawnmower to operate in range-extended mode if the current state of charge value is less than the upper limit threshold, and to control the lawnmower to operate in pure electric mode if the current state of charge value is greater than the upper limit threshold. The range-extended mode is a mode in which the lawnmower uses a range extender to provide power to its own power-consuming devices and uses the remaining energy of the range extender to charge its own power battery. The pure electric mode is a mode in which the lawnmower uses only the power battery to provide power to its own power-consuming devices.

[0026] Optionally, the lawnmower power mode control device further includes:

[0027] The control unit is used to control the lawnmower to operate in pure electric mode when it detects that the lawnmower has changed from a stopped state to a started state;

[0028] The signal monitoring unit is used to monitor whether the target signal has been triggered by the local preset device. If the target signal has been triggered by the local preset device, the corresponding workflow of the status monitoring module is triggered.

[0029] Thirdly, this application provides an electronic device, comprising:

[0030] Memory, used to store computer programs;

[0031] A processor is used to execute the computer program to implement the aforementioned lawnmower power mode control method.

[0032] Fourthly, this application provides a computer-readable storage medium for storing a computer program, wherein the computer program, when executed by a processor, implements the aforementioned lawnmower power mode control method.

[0033] In this application, the current working status of the lawnmower is monitored in real time to obtain the current operating condition of the lawnmower; the current operating condition is either a mowing condition or a non-mowing condition; the current state of charge (SOC) value of the lawnmower under the current operating condition is determined, and a preset SOC value corresponding to the operating condition type of the current condition is determined; wherein, the current SOC value is used to reflect the remaining power of the lawnmower under the current operating condition, and the preset SOC value includes a lower SOC threshold and an upper SOC threshold; if the current SOC value is less than the lower SOC threshold, the lawnmower is controlled to operate in range-extended mode; if the current SOC value is greater than the upper SOC threshold, the lawnmower is controlled to operate in pure electric mode; the range-extended mode is a mode in which the lawnmower uses a range extender to provide power to its own power-consuming devices, and uses the remaining energy of the range extender to charge its own power battery; the pure electric mode is a mode in which the lawnmower uses only the power battery to provide power to its own power-consuming devices. As can be seen from the above, this application monitors the current working status of the lawnmower in real time to obtain the current working condition of the lawnmower, and compares the current state of charge value of the lawnmower with the preset state of charge value corresponding to the working condition type of the lawnmower, thereby controlling the lawnmower to automatically switch between range-extended mode and pure electric mode; it meets the complex power requirements of the lawnmower under different working conditions, solves the problem of automatic power mode switching of electric lawnmowers, improves mowing efficiency, and reduces energy waste.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Early electric lawnmowers mostly operated in pure electric mode, relying solely on batteries for power. This mode had significant limitations. For example, when the battery charge was low, the lawnmower's performance dropped drastically. To overcome the range limitations of pure electric lawnmowers, range-extended electric lawnmowers were developed. However, existing range-extended electric lawnmowers have many shortcomings in power mode switching. Some models require manual operation for power mode switching, which not only increases the operator's workload but also makes it easy for human error or delayed operation to cause the vehicle to be in the wrong power mode at an inappropriate time. Therefore, this application provides a lawnmower power mode control method that can automatically switch the lawnmower's power mode based on the current state of charge, solving the problem of automatic power mode switching for electric lawnmowers.

[0042] See Figure 1 As shown in the figure, an embodiment of the present invention discloses a method for controlling the power mode of a lawnmower, including:

[0043] Step S11: Monitor the current working status of the lawnmower in real time to obtain the current working condition of the lawnmower; the current working condition is either a lawnmower working condition or a non-lawnmower working condition.

[0044] In this embodiment, after the lawnmower is started, there are two working states: a mowing state and a non-mowing state. Real-time monitoring of the current working state of the lawnmower can include: real-time monitoring of the current working state of the lawnmower and determining whether the mower blades are in the starting state and whether there is at least one drive motor with a speed greater than zero in the lawnmower. If the mower blades are in the starting state and there is at least one drive motor with a speed greater than zero in the lawnmower, then the current working state of the lawnmower is determined to be a mowing state. If the mower blades are not in the starting state and / or there is no drive motor with a speed greater than zero in the lawnmower, then the current working state of the lawnmower is determined to be a non-mowing state.

[0045] Understandably, determining the mowing condition requires checking the status of the cutter switch. When the cutter switch is on, it indicates that the mower may be in the process of mowing. However, this is not the only criterion. The speed of the mower's drive motors must also be considered. If the speed of any drive motor is greater than 0, it indicates that the mower is in motion and the cutter is either ready to work or is in operation; in this case, it can be determined to be in mowing condition. This dual-judgment mechanism effectively avoids erroneous judgments due to operational errors or equipment malfunctions, ensuring the accuracy of the mowing condition assessment. To determine if a lawnmower is not in a mowing condition, it can be preliminarily identified as such when the mower's blade switch is off and / or there is no drive motor with a speed greater than zero in the lawnmower. However, the actual situation may be more complex. For example, when the lawnmower pauses briefly but the system is still powered on, it is necessary to further eliminate other factors that may affect the judgment, such as whether the system is in a special state such as preheating, self-testing, or standby. By comprehensively analyzing the data from various sensors of the lawnmower, the status of the electrical system, and the historical records of operating commands, the non-mowing condition can be determined more accurately, providing a reliable basis for the reasonable switching of the power mode.

[0046] Step S12: Determine the current state of charge value of the lawnmower under the current working condition, and determine the preset state of charge value corresponding to the working condition type of the current working condition; wherein, the current state of charge value is used to reflect the remaining power of the lawnmower under the current working condition, and the preset state of charge value includes a lower limit threshold and an upper limit threshold.

[0047] In this embodiment, determining the state of charge (SOC) value of the lawnmower under the current operating condition and the preset state of charge value corresponding to the operating condition type is one of the core links in the entire power mode control system, and plays a key role in achieving accurate and efficient power mode switching.

[0048] For different operating conditions, namely mowing and non-mowing, the corresponding preset state of charge (SOC) values ​​are set based on a detailed analysis of the energy consumption patterns and vehicle performance requirements under each condition. During mowing, energy consumption is relatively high and stable because mowing requires driving the cutter blades and maintaining vehicle movement. Therefore, the lower limit of the SOC threshold is set relatively high to ensure that the range extender mode is activated in time before the battery level drops to a point that might affect the mowing performance, ensuring the continuity and efficiency of mowing operations. Meanwhile, the upper limit of the SOC threshold is relatively moderate; when the battery level recovers to a certain level, it switches back to pure electric mode, fully utilizing the battery's energy while meeting mowing needs, reducing the range extender's operating time, and lowering energy consumption and noise. During non-mowing, the vehicle's energy consumption is mainly focused on maintaining basic electrical system operation and a small amount of movement, resulting in relatively low energy consumption. Therefore, the lower limit of the SOC threshold is set relatively low; the upper limit of the SOC threshold is also correspondingly low to ensure that pure electric mode is maintained when the battery is sufficiently charged, further improving energy efficiency.

[0049] By setting preset state of charge values ​​for different working conditions and combining real-time monitoring and comparison of the current state of charge value, the lawnmower's power mode can be switched intelligently and precisely, enabling the lawnmower to maintain optimal performance and energy utilization under various working conditions, effectively extending battery life, and improving user experience and work efficiency.

[0050] Step S13: If the current state of charge (SBC) value is less than the upper limit threshold, the lawnmower is controlled to operate in range-extended mode; if the current SBC value is greater than the upper limit threshold, the lawnmower is controlled to operate in pure electric mode. The range-extended mode is a mode in which the lawnmower uses a range extender to provide power to its own power-consuming devices and uses the remaining energy of the range extender to charge its own power battery. The pure electric mode is a mode in which the lawnmower uses only the power battery to provide power to its own power-consuming devices.

[0051] In this embodiment, the current operating condition of the lawnmower is first determined. When the current operating condition is not mowing, if the current state of charge (SBC) value of the lawnmower is less than the first SBC threshold, the lawnmower is controlled to operate in range-extended mode to avoid the lawnmower's own power battery being too low and causing the lawnmower's drive motor to fail to work. If the current SBC value of the lawnmower is greater than the first SBC threshold, the lawnmower is controlled to operate in pure electric mode. When the current operating condition is mowing, if the current SBC value of the lawnmower is less than the second SBC threshold, the lawnmower is controlled to operate in range-extended mode to maintain the lawnmower's own power battery discharge performance at a high level to meet the power demand during mowing. If the current SBC value of the lawnmower is greater than the second SBC threshold, the lawnmower is controlled to operate in pure electric mode.

[0052] Among them, the upper limit threshold of the second state of charge is greater than the lower limit threshold of the second state of charge, the lower limit threshold of the second state of charge is greater than the upper limit threshold of the first state of charge, and the upper limit threshold of the first state of charge is greater than the lower limit threshold of the first state of charge.

[0053] It should be noted that when the lawnmower is detected to transition from a stopped state to a started state, the system controls the lawnmower to operate in pure electric mode and monitors whether the target signal has been triggered by the local preset device. If the target signal has been triggered, the system jumps to the step of real-time monitoring of the lawnmower's current operating status to obtain its current working condition. This process design allows the lawnmower to smoothly transition from the start-up phase to the phase of dynamically adjusting the power mode according to actual working conditions, ensuring the continuity and accuracy of the entire power mode control process. In this way, the lawnmower can efficiently utilize electric energy and the range extender's function under different operating phases and conditions, improving overall performance and energy efficiency, and providing users with stable and reliable lawnmowing services.

[0054] See Figure 2 The diagram shown illustrates the power modes of the range-extended electric lawnmower. The lawnmower's power mode is automatically switched based on its current state of charge (SOC). When switching from pure electric mode to range-extended mode, the range extender starts and generates electricity to increase the lawnmower's SOC. When switching back to pure electric mode, the range extender stops working, and the lawnmower's battery provides the necessary power.

[0055] As can be seen from the above, this embodiment monitors the current working status of the lawnmower in real time to obtain its current operating condition, and compares the current state of charge (SBC) value of the lawnmower with the preset SBC value corresponding to the current operating condition type, thereby controlling the lawnmower to automatically switch between range-extended mode and pure electric mode. In this way, by controlling the lawnmower's power mode to automatically switch according to its current SBC value, blade on / off status, and drive status, the complex power requirements of the lawnmower under different operating conditions are met, the problem of automatic power mode switching of electric lawnmowers is solved, the mowing efficiency is improved, and energy waste is reduced.

[0056] See Figure 3 As shown below, the technical solution in this application will be explained using a specific flowchart of the power mode control method for a range-extended electric lawnmower as an example.

[0057] When the lawnmower is detected to change from a stopped state to a started state, the control system will operate the lawnmower in pure electric mode by default and monitor whether the target signal of the local preset device has been triggered. If the target signal of the local preset device has been triggered, the current working condition of the lawnmower will be judged, and the current working condition of the lawnmower will be monitored in real time to obtain the current working condition of the lawnmower. If the lawnmower's blade is in the started state and there is at least one drive motor with a speed greater than zero in the lawnmower, that is, the blade is turned on and the speed of any drive motor is greater than zero, then the current working condition of the lawnmower is determined to be the mowing condition. If the lawnmower's blade is not in the started state and / or there is no drive motor with a speed greater than zero in the lawnmower, then the current working condition of the lawnmower is determined to be the non-mowing condition.

[0058] When the lawnmower is in mowing mode, a preset state of charge (SOC) value corresponding to the current working condition type is set. The preset SOC value includes a second SOC lower limit threshold and a second SOC upper limit threshold. It is then determined whether the current SOC of the lawnmower is less than the second SOC lower limit threshold. If so, the lawnmower is controlled to switch to range-extended mode, i.e., requesting the range extender to generate electricity. After receiving the request signal, the range extender starts generating electricity so that the lawnmower can use the range extender to provide power to its own power-consuming components and use the remaining energy of the range extender to charge its own power battery, thereby increasing its SOC. Then, it is determined whether the current SOC of the lawnmower is greater than the second SOC upper limit threshold. If so, the lawnmower is controlled to switch to pure electric mode. At this time, the range extender stops working so that the lawnmower can only use the power battery to provide power to its own power-consuming components.

[0059] When the lawnmower is not in mowing mode, a preset state of charge (SOC) value corresponding to the current operating condition is set. The preset SOC value includes a first SOC lower limit threshold and a first SOC upper limit threshold. It is then determined whether the current SOC of the lawnmower is less than the first SOC lower limit threshold. If so, the lawnmower is controlled to switch to range-extended mode, i.e., requesting the range extender to generate electricity. After receiving the request signal, the range extender starts generating electricity so that the lawnmower can use the range extender to provide power to its own power-consuming components and use the remaining energy of the range extender to charge its own power battery, thereby increasing its SOC. Then, it is determined whether the current SOC of the lawnmower is greater than the first SOC upper limit threshold. If so, the lawnmower is controlled to switch to pure electric mode. At this time, the range extender stops working so that the lawnmower can only use the power battery to provide power to its own power-consuming components.

[0060] As can be seen from the above, this embodiment takes a specific schematic diagram of the power mode control method of a range-extended electric lawnmower as an example, and elaborates in detail how to control the automatic switching of the power mode of the lawnmower based on the current state of charge value, the blade opening state, and the driving state of the lawnmower, thus solving the problem of automatic switching of the power mode of the range-extended electric lawnmower.

[0061] See Figure 4 As shown in the embodiments, this application also discloses a lawnmower power mode control device, including:

[0062] The status monitoring module 11 is used to monitor the current working status of the lawnmower in real time to obtain the current working condition of the lawnmower; the current working condition is either a lawnmower working condition or a non-lawnmower working condition.

[0063] The state of charge (SCC) determination module 12 is used to determine the current SCC value of the lawnmower under the current working condition and to determine a preset SCC value corresponding to the working condition type of the current working condition; wherein, the current SCC value is used to reflect the remaining power of the lawnmower under the current working condition, and the preset SCC value includes a lower threshold for the SCC value and an upper threshold for the SCC value.

[0064] The mode control module 13 is used to control the lawnmower to operate in range-extended mode if the current state of charge value is less than the upper limit threshold of the state of charge, and to control the lawnmower to operate in pure electric mode if the current state of charge value is greater than the upper limit threshold of the state of charge. The range-extended mode is a mode in which the lawnmower uses a range extender to provide power to its own power-consuming devices and uses the remaining energy of the range extender to charge its own power battery. The pure electric mode is a mode in which the lawnmower uses only the power battery to provide power to its own power-consuming devices.

[0065] As can be seen from the above, this application monitors the current working status of the lawnmower in real time to obtain its current operating condition, and compares the current state of charge (SBC) value of the lawnmower with the preset SBC value corresponding to the current operating condition type, thereby controlling the lawnmower to automatically switch between range-extended mode and pure electric mode. In this way, by controlling the lawnmower's power mode to automatically switch according to its current SBC value, the complex power requirements of the lawnmower under different operating conditions are met, the problem of automatic power mode switching of electric lawnmowers is solved, the mowing efficiency is improved, and energy waste is reduced.
