Technical Field

[0001] This application relates to the field of smart home technology, specifically to a control method and system for an electric lift bed in a motorhome, and a storage medium. Background Technology

[0002] To improve the space utilization inside the RV, an electric lift bed is installed. When the user wants to use the electric lift bed, it can be lowered to a suitable height for sleeping, resting, etc. When the user does not use the electric lift bed, it can be raised to the roof of the RV, and the space below the electric lift bed can be used for other activities such as eating and entertainment.

[0003] However, in practice, it has been found that the electric lifting bed will experience a certain degree of wear and tear during use, leading to its inability to function properly. Therefore, it is necessary to inspect the electric lifting bed to determine if there is a malfunction. In related technologies, users typically use regular manual maintenance to inspect the electric lifting bed. However, this method cannot detect malfunctions in a timely manner, which will affect the normal use of the electric lifting bed. Summary of the Invention

[0010] As an optional implementation, in the first aspect of the embodiments of this application, determining the maintenance requirements for the electric lifting bed based on the driving data and the usage data includes:

[0011] Based on the usage time of the electric lifting bed, a first part of the driving data and a second part of the driving data are determined from the driving data. The first part of the driving data is the portion of the driving data that matches the usage time of the electric lifting bed, and the second part of the driving data is the remaining driving data excluding the first part of the driving data.

[0065] 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.

Therefore, "in one embodiment," "in one embodiment," or "some embodiments" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

Those skilled in the art should understand that the above-described multiple embodiments can also be combined arbitrarily.

[0068] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are used to distinguish similar or different objects and are not related to a specific order of the objects being described. It is understood that "first," "second," and "third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0069] The terms “comprising” and “having”, and any variations thereof, in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0071] To improve the utilization of interior space in RVs, various foldable or height-adjustable smart furniture is installed. Electric lift beds are one such type of smart furniture, offering advantages such as small footprint and ease of use, making them an indispensable piece of equipment for RV travel. During use, users can control the electric lift bed to rise or fall for various purposes, providing more space. For example, when users want to rest or sleep, they can control the electric lift bed to lower to a suitable height (e.g., 0.5 meters from the RV floor). When not in use, the electric lift bed can be raised to the roof of the RV. The controls below the electric lift bed allow users to eat, entertain themselves, and engage in other activities.

[0072] However, in practice, it has been found that electric lifting beds experience wear and tear over long-term use due to factors such as usage frequency and road conditions, thus affecting their normal operation. Therefore, timely inspection and maintenance are necessary to determine if any malfunctions exist. Currently, users rely on periodic manual maintenance to inspect electric lifting beds. This method cannot promptly detect faults or provide personalized maintenance based on the specific usage conditions, further impacting the normal operation of the lifting bed.

[0073] In view of this, embodiments of this application provide a control method and system for an electric lift bed in a motorhome, and a storage medium. The method includes: acquiring driving data of the motorhome and usage data of the electric lift bed, wherein the driving data includes at least one of the motorhome's mileage information, driving speed, road conditions, and number of start-stop cycles; and the usage data includes the usage time of the electric lift bed, the number of times it jammed during use, and the number of times the lifting position failed to reach a preset position. Based on the driving data and the usage data, a maintenance requirement for the electric lift bed is determined; and in response to the maintenance requirement, an operation corresponding to the maintenance requirement is executed. This method can automatically determine whether the electric lift bed needs maintenance based on the motorhome's driving data and the electric lift bed's usage data, helping users to promptly understand whether the electric lift bed has a malfunction, thus ensuring the normal operation of the electric lift bed.

[0074] The following is a detailed description of a control method for an electric lift bed for a motorhome disclosed in this application, with reference to the accompanying drawings.

[0075] Please see Figure 1 This is a structural schematic diagram of an electric lift bed for a motorhome disclosed in an embodiment of this application. Figure 1 As shown, the electric lift bed 101 of the RV includes a movable connecting part 102, a frame 103, folding wings 104, and a lighting device 105. It should be noted that... Figure 1The electric lifting bed 101 shown may also include components not shown, such as a control device, a shooting device, a recognition device, a sensor, a data storage device, and a communication module. This application embodiment does not limit these components.

[0076] Please see Figure 2 This is a flowchart illustrating the first embodiment of a control method for an electric lift bed in a motorhome disclosed in this application. Figure 2 As shown, the method may include the following steps:

[0077] 201. Obtain the driving data of the RV and the usage data of the electric lift bed of the RV. The driving data includes at least one of the following: mileage information, driving speed, road conditions, and number of start-stop times of the RV. The usage data includes the usage time of the electric lift bed, the number of times it jams during use, and the number of times the lifting position fails to reach the preset position.

[0078] The RV is equipped with a navigation system that can retrieve driving data. This navigation system can be the RV's in-vehicle navigation system or a navigation system from an electronic device used by the RV driver. The electronic device used by the RV driver can be a mobile phone, tablet, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. Wearable devices can include smartwatches, smart bracelets, smart ankle bracelets, smart earrings, smart necklaces, smart headphones, etc., and this application embodiment is not limited to any particular type.

[0079] In this embodiment, the driving data includes at least one of the following: mileage information, driving speed, road conditions, and number of starts and stops. The mileage information includes the RV's travel distance and time; the road conditions include the location and direction of curves along the driving path, as well as the lane type; and the number of starts and stops includes the number of times the RV starts and brakes. Those skilled in the art can obtain the necessary RV driving data according to actual conditions, which will not be listed here.

[0080] In this embodiment, the electric lifting bed is equipped with sensors, such as photoelectric sensors and pressure sensors, which can be used to acquire usage data of the electric lifting bed. The usage data includes the usage time of the electric lifting bed, the number of times it jams during use, and the number of times the lifting position fails to reach the preset position. Those skilled in the art can obtain the required usage data of the electric lifting bed according to actual conditions, which will not be listed here.

[0081] In some embodiments, driving data of the RV and usage data of the electric lift bed can be collected at preset sampling intervals, such as once every hour. Alternatively, the user can actively collect the driving data and usage data of the RV and electric lift bed; this is not limited to any particular method. The electric lift bed is equipped with a data storage device, such as a hard drive, flash memory, or cloud storage. This data storage device can be used to store the driving data of the RV and the usage data of the electric lift bed, facilitating retrieval of the driving and usage data. Furthermore, it allows users or manufacturers to view and analyze the driving and usage data, enabling them to understand the usage of the electric lift bed.

[0082] 202. Based on the driving data and the usage data, determine the maintenance requirements for the electric lifting bed.

[0083] Because using the electric lift bed while the RV is in motion will cause wear and tear on the electric lift bed, affecting its normal operation, and even when the electric lift bed is not used while the RV is in motion, factors such as road conditions and the number of starts and stops will still cause some wear and tear on the electric lift bed. Therefore, in order to determine whether the electric lift bed needs maintenance, it is necessary to comprehensively determine the degree of wear and tear under both scenarios: when the electric lift bed is in motion and when it is not used. The maintenance needs of the electric lift bed can then be further determined based on the degree of wear and tear.

[0084] In this embodiment of the application, determining the maintenance needs of the electric lifting bed based on driving data and usage data may include the following steps:

[0085] S11: Based on the usage time of the electric lifting bed, determine the first part of the driving data and the second part of the driving data from the driving data. The first part of the driving data is the driving data that matches the usage time of the electric lifting bed, and the second part of the driving data is the remaining driving data excluding the first part of the driving data.

[0086] S12: Determine the first degree of wear of the electric lifting bed based on the first part of the driving data, the first depreciation coefficient, and the preset correspondence between driving data, usage data, and degree of wear;

[0087] S13: Based on the second part of the driving data, the second depreciation coefficient, and the preset correspondence between driving data and depreciation degree, determine the second depreciation degree of the electric lifting bed, where the first depreciation coefficient is greater than the second depreciation coefficient;

[0088] S14: When the sum of the first degree of wear and the second degree of wear is greater than or equal to the wear threshold, determine the maintenance requirements for the electric lifting bed.

[0089] The steps S11-S14 above are explained in detail below:

[0090] First, based on the usage time of the electric lift bed, a first portion of driving data matching the usage time of the electric lift bed is determined from the driving data. This first portion of driving data represents the RV's driving data when the electric lift bed is used, i.e., the electric lift bed is used during the RV's driving process. Then, a second portion of driving data is determined based on the first portion of driving data. This second portion of driving data consists of all driving data of the RV except for the first portion. This second portion of driving data represents the RV's driving data when the electric lift bed is not used, i.e., the electric lift bed is not used during the RV's driving process. For example, if the RV's driving time is 1:00-12:00 and the electric lift bed's usage time is 1:00-8:00, the driving data for the period from 1:00-8:00 is determined as the first portion of driving data, and the driving data for the period from 8:00-12:00 is determined as the second portion of driving data, where the electric lift bed is not used during the period from 8:00-12:00.

[0091] Secondly, in some embodiments, a first wear coefficient for the electric lift bed can be determined based on the first portion of the RV's driving data. The first portion of the driving data includes at least one of the RV's mileage information, driving speed, road conditions, and number of starts and stops. The first wear coefficient is the wear coefficient of the electric lift bed when used during RV operation. The wear coefficient represents the wear ratio of the electric lift bed; a larger wear coefficient indicates a larger wear ratio. For example, if the RV's mileage is 10,000 kilometers, the first wear coefficient for the electric lift bed is 0.1; if the RV's mileage is 20,000 kilometers, the first wear coefficient for the electric lift bed is 0.2.

[0092] In some embodiments, a neural network model can be used to pre-determine the correspondence between driving data, usage data, and wear and tear. The driving data includes at least one of the following: mileage information of the RV, driving speed, road conditions, and number of starts and stops. The usage data includes the usage time of the electric lift bed, the number of times it jammed during use, and the number of times the lifting position failed to reach the preset position. Specifically: First, driving data of the RV and usage data of the electric lift bed are collected in advance, corresponding to the time when the electric lift bed needs maintenance. Then, a neural network model is established using a convolutional neural network (CNN). The driving data of the RV and the usage data of the electric lift bed are input into the neural network model for training. The driving data of the RV and the usage data of the electric lift bed are divided into a training set and a validation set. The training set is used to train the neural network model, and the validation set is used to evaluate the model's performance and adjust the model's parameters. During training, optimization algorithms such as stochastic gradient descent (SGD) can be used to optimize the parameters of the neural network model to improve the model's performance and accuracy. Finally, a neural network model is formed that establishes a correspondence between driving data, usage data, and the degree of wear and tear. This trained model can be used to predict the degree of wear and tear on the electric lift bed. Specifically, the driving data of the RV and the usage data of the electric lift bed are input into the neural network model. Through the model's calculations and predictions, the degree of wear and tear on the electric lift bed can be obtained. For example, if the RV has traveled 10,000 kilometers and the electric lift bed has been used for 1,000 hours, the degree of wear and tear on the electric lift bed is 10%; if the RV has traveled 10,000 kilometers and the electric lift bed has been used for 1,500 hours, the degree of wear and tear on the electric lift bed is 15%, and so on.

[0093] In other embodiments, the correspondence between driving data, usage data, and wear level can be obtained through experiments or experience. Alternatively, a wear level mapping table can be established to pre-determine the correspondence between driving data, usage data, and wear level; this is not limited here. For example, the correspondence between driving data, usage data, and wear level can be queried from the wear level mapping table, which records the mapping relationship between driving data, usage data, and wear level, wherein driving data, usage data, and wear level are in a one-to-one correspondence.

[0094] In this embodiment, the first degree of wear of the electric lift bed is determined based on the first portion of the RV's driving data, the first wear coefficient of the electric lift bed, and a preset correspondence between driving data, usage data, and wear level. The first degree of wear refers to the degree of wear of the electric lift bed when used during RV driving. For example, if the electric lift bed has been used for 500 hours and the RV has traveled 10,000 kilometers, with the first portion of the travel being 5,000 kilometers, the first wear coefficient of the electric lift bed is 0.05 based on the first portion of the travel. Then, based on the first portion of the travel, the first wear coefficient, and the preset correspondence between driving data, usage data, and wear level (e.g., RV travel mileage is 5,000 kilometers, electric lift bed usage time is 500 hours, electric lift bed wear level is 5%), the first degree of wear of the electric lift bed is determined to be 5%.

[0095] Secondly, in some embodiments, a second depreciation coefficient for the electric lift bed can be determined based on the second part of the RV's driving data. This second part of the driving data includes at least one of the following: mileage information, driving speed, road conditions, and number of starts and stops. The second depreciation coefficient is the depreciation coefficient of the electric lift bed when it is not used during RV operation. Since using the electric lift bed during RV operation accelerates its depreciation, thus increasing its wear and tear, the first depreciation coefficient is greater than the second depreciation coefficient. For example, if the RV has traveled 10,000 kilometers and the electric lift bed is not used, the second depreciation coefficient is 0.01, and the first depreciation coefficient is 0.1; if the RV has traveled 20,000 kilometers, the second depreciation coefficient is 0.02, and the first depreciation coefficient is 0.2.

[0096] In some embodiments, a neural network model can be used to pre-determine the correspondence between driving data and wear levels. The driving data includes at least one of the following: mileage information of the RV, driving speed, road conditions, and number of starts and stops. In this embodiment, obtaining the correspondence between driving data and wear levels through a neural network model is similar to the aforementioned method of pre-determining the correspondence between driving data, usage data, and wear levels using a neural network model, and will not be repeated here. For example, when the RV's mileage is 10,000 kilometers, the wear level of the electric lift bed is 1%; when the mileage is 20,000 kilometers, the wear level of the electric lift bed is 2%, etc.

[0097] In this embodiment, the second degree of wear of the electric lift bed is determined based on the second portion of the RV's driving data, the second wear coefficient of the electric lift bed, and a preset correspondence between driving data and wear level. The second degree of wear refers to the degree of wear of the electric lift bed when it is not used during RV driving. For example, if the RV's mileage is 10,000 kilometers, with the first portion being 5,000 kilometers, the second wear coefficient of the electric lift bed is 0.005 based on the first portion of the mileage. Then, based on the second portion of the driving data, the second wear coefficient, and the preset correspondence between driving data and wear level (e.g., if the RV's mileage is 5,000 kilometers, the wear level of the electric lift bed is 0.5%), the first degree of wear of the electric lift bed is determined to be 0.5%.

[0098] Finally, when the sum of the first and second wear levels is greater than or equal to the wear level threshold, the maintenance requirement for the electric lift bed is determined. For example, if the first wear level of the electric lift bed is 10% when it is used while the RV is in motion, and the second wear level is 1% when it is not used while the RV is in motion, the sum of the first and second wear levels is 10.1%. Assuming the wear level threshold is 10%, then the electric lift bed needs maintenance. Those skilled in the art can determine the wear level threshold through experiments or experience, which is not limited here.

[0099] As an alternative implementation method, based on driving data and usage data, the maintenance requirements for the electric lifting bed can be determined in the following ways:

[0100] Based on the RV's travel time, a first part of the usage data and a second part of the usage data are determined from the usage data of the electric lift bed. The first part of the usage data is the usage data that matches the RV's travel time, and the second part of the usage data is the remaining usage data excluding the first part of the usage data.

[0101] Based on the usage data in Part 1, the third depreciation coefficient, and the preset correspondence between driving data, usage data, and degree of wear, the third degree of wear of the electric lifting bed is determined.

[0102] Based on the usage data in the second part, the fourth wear coefficient, and the preset correspondence between usage data and wear level, the fourth wear level of the electric lifting bed is determined, wherein the third wear coefficient is greater than the fourth wear coefficient;

[0103] When the sum of the third degree of wear and the fourth degree of wear is greater than or equal to the wear threshold, the maintenance requirement for the electric lifting bed is determined.

[0104] In the above optional embodiments, when the user uses the electric lift bed, the RV may be in a driving state or a parked state. When the RV is in a driving state, the wear and tear on the electric lift bed will be accelerated. Therefore, it is necessary to detect the degree of wear and tear of the electric lift bed in both situations. When the sum of the degree of wear and tear of the electric lift bed in the two situations is greater than or equal to the wear and tear threshold, it can be determined that the electric lift bed needs to be repaired. The detailed steps for determining whether the electric lift bed needs repair using the above optional embodiments can be referred to the detailed steps of S11-S14 above, and will not be repeated here.

[0105] 203. In response to the maintenance request, perform the operation corresponding to the maintenance request.

[0106] In this embodiment, upon determining that the electric lifting bed requires maintenance, the system responds to the maintenance request by executing corresponding operations, including: outputting maintenance reminder information to remind the user to perform maintenance on the electric lifting bed. Specifically, upon determining that the electric lifting bed requires maintenance, the reminder information can be sent to the user's mobile phone or other electronic device, to the electric lifting bed manufacturer, or to the RV's onboard system, which then notifies the user of the maintenance reminder information. The maintenance reminder information can be sent to the user via SMS or voice broadcast; this is not limited to these methods.

[0107] As can be seen, implementing the embodiments of this application allows for the determination of whether the electric lift bed requires maintenance based on the RV's driving data and usage data, helping users to promptly understand whether the electric lift bed is malfunctioning. It also allows for the determination of the degree of wear and tear on the electric lift bed during RV operation, both when in use and when not in use, and based on this wear level, determines whether maintenance is necessary, improving the accuracy of fault detection. Establishing a correspondence between driving data, usage data, and wear level using a neural network model allows for a more accurate determination of the electric lift bed's wear level. Furthermore, when a malfunction is detected requiring maintenance, the user is promptly notified, ensuring timely maintenance of the electric lift bed.

[0108] Please see Figure 3 This is a flowchart illustrating a second embodiment of a control method for an electric lift bed in a motorhome disclosed in this application. Figure 3 The method shown includes the following implementation steps:

[0109] 301. Obtain the driving data of the RV and the usage data of the electric lift bed of the RV. The driving data includes at least one of the following: mileage information, driving speed, road conditions, and number of starts and stops of the RV. The road conditions include the location of curves in the driving path, the direction of the curves, and the lane type of the driving path. The electric lift bed is fixed to the RV by multiple movable connectors.

[0110] In this embodiment, the driving conditions include the location of curves, the direction of curves, and the lane type of the driving path. The location of curves reflects the number of curves in the RV's driving path; more curves result in greater wear and tear on the electric lift bed. If multiple curves share the same direction, the wear and tear on the electric lift bed is also greater. The lane type reflects the smoothness of the RV's driving path; greater smoothness results in greater wear and tear on the electric lift bed.

[0111] The electric lift bed 101 of the RV includes movable connectors 102, and the electric lift bed is fixed to the RV through multiple movable connectors. Specifically, the electric lift bed operates by controlling its raising, lowering, and fixing to adapt to different usage scenarios. Therefore, multiple movable connectors are needed to install the electric lift bed on the RV. When the user controls the raising, lowering, and fixing of the electric lift bed, these actions can be achieved through the multiple movable connectors.

[0112] For further details regarding step 301, please refer to the relevant description in step 201 of the first embodiment mentioned above, which will not be repeated here.

[0113] 302. Based on the driving data and the usage data, determine the maintenance requirements for the electric lifting bed.

[0114] For details on step 302, please refer to the relevant description in step 202 of the first embodiment mentioned above, which will not be repeated here.

[0115] 303. Based on the curve location, the curve direction, and the lane type, determine a target movable connector from the plurality of movable connectors. The target movable connector is a movable connector that keeps the electric lifting bed from shifting at the curve during the RV's operation.

[0116] Since movable connectors are used to raise, lower, and fix the electric lift bed, factors such as the direction and angle of the curve and the type of lane can affect the stability of the electric lift bed when the RV is traveling on curves or bumpy roads. Therefore, movable connectors are needed to prevent the electric lift bed from shifting relative to the RV. Movable connectors allow the electric lift bed to be used normally even on curves. The target movable connector is the one among multiple movable connectors that keeps the electric lift bed from shifting relative to the RV on curves. It is understood that there can be multiple target movable connectors, or it can be the one with the greatest wear and tear when the RV is traveling on a curve; this is not limited here.

[0117] In some embodiments, the correspondence between the curve position, curve direction, lane type, and movable connector of the RV can be preset. For example, if there are the most left-hand curves, the movable connector 1 will be damaged; if there are the most right-hand curves, the movable connector 2 will be damaged. The correspondence can be determined by a neural network model. For specific methods, please refer to the relevant introduction about the neural network model in step 202 of the first embodiment above, which will not be repeated here.

[0118] In this embodiment of the application, a target movable connector can be determined from multiple movable connectors based on the curve position, curve direction, lane type in the RV's driving path and the corresponding relationship between the preset RV's curve position, curve direction, lane type and movable connector. The target movable connector is a movable connector that keeps the electric lifting bed from shifting at the curve during the RV's driving process.

[0119] 304. In response to the maintenance request, output maintenance prompt information, which includes information about the target movable connector.

[0120] Since the target movable connector is a crucial component that prevents the electric lift bed from shifting during RV travel, frequent curves in RV travel accelerate its wear and tear. Therefore, after determining the maintenance needs of the electric lift bed, the maintenance prompt information output in response to the maintenance request also includes information about the target movable connector, such as the degree of wear and whether it needs maintenance or replacement.

[0121] For further details regarding step 304, please refer to the relevant description in step 203 of the first embodiment mentioned above, which will not be repeated here.

[0122] As can be seen, implementing the embodiments of this application allows for the determination of whether the electric lift bed requires maintenance based on the RV's driving data and the usage data of the electric lift bed, helping users to promptly understand whether the electric lift bed is malfunctioning. It can also detect whether the movable connectors connecting the electric lift bed and the RV are faulty and prompt the user whether the movable connectors need maintenance. By establishing the correspondence between the RV's curve position, curve direction, lane type, and movable connectors using a neural network model, the target movable connector can be identified more accurately.

[0123] Please see Figure 4 This is a flowchart illustrating a third embodiment of a control method for an electric lift bed in a motorhome disclosed in this application. Figure 4 The method shown includes the following implementation steps:

[0124] 401. Obtain the driving data of the RV, wherein the driving data is at least one of the following: mileage information, driving speed, road conditions, and number of starts and stops of the RV, and the road conditions include the location of curves in the driving path, the direction of the curves, and the lane type of the driving path.

[0125] For details on step 401, please refer to the relevant descriptions in steps 201 and 301 in the aforementioned embodiments, which will not be repeated here.

[0126] 402. Based on the curve location, the curve direction, and the lane type, predict the target movement direction of the user on the electric lifting bed.

[0127] When a motorhome travels on curves or bumpy roads, factors such as the direction and angle of the curve and the type of road can affect the stability of the electric lift bed. When the electric lift bed is unstable, the user is more likely to fall off. Therefore, to prevent falls and improve the user experience, it is necessary to anticipate the user's intended movement direction in advance to control the bed and protect the user. The intended movement direction is the direction the user moves when their position on the electric lift bed changes while the motorhome is traveling on a curve or bumpy road. For example, if the user's initial position on the electric lift bed is 'a', and the user moves from position 'a' to position 'b' when the motorhome travels on a curve or bumpy road, the direction of movement from position 'a' to position 'b' is the intended movement direction.

[0128] As an optional implementation, predicting the target movement direction of the user on the electric lifting bed based on the curve location, the curve direction, and the lane type may include the following steps:

[0129] Obtain the initial position of the user on the electric lifting bed;

[0130] Based on the curve position, curve direction, lane type, and the preset correspondence between curve position, curve direction, lane type, and movement position, the target movement position of the user on the electric lifting bed is predicted; the target movement position is different from the initial position.

[0131] Based on the initial position and the predicted target movement position, predict the target movement direction of the user on the electric lifting bed.

[0132] In one of the above optional embodiments, the electric lifting bed is equipped with sensors, imaging devices, etc., and the type of sensors and imaging devices is not limited in this application. Specifically, a pressure sensor can be used to detect the user's initial position on the electric lifting bed, or an imaging device can be used to capture the user's initial position on the electric lifting bed; this is not limited here.

[0133] In one of the above optional embodiments, the acceleration and angle of the RV when driving on a curve can be detected using an accelerometer to determine the direction and angle of the curve. The preset correspondence between the curve position, curve direction, lane type, and movement position can be determined by a neural network model. For specific methods, please refer to the relevant introduction about the neural network model in step 202 of the first embodiment above, which will not be repeated here.

[0134] In one of the above optional embodiments, the target movement position is a position of the user on the electric lifting bed that differs from the initial position. When predicting the target movement position, the prediction can be made based on a preset correspondence between curve position, curve direction, lane type, and movement position. The target movement position is different from the initial position. For example, when a curve direction of 30 degrees relative to the horizontal line of the RV is detected as left, it is predicted that the user on the electric lifting bed will move to the target movement position relative to the initial position. By establishing a correspondence, the user's target movement position can be predicted more accurately.

[0135] In one optional implementation described above, the target movement direction and target movement distance of the user on the electric lifting bed are predicted based on the initial position and the target movement position. Specifically, the initial position and the target movement position can be represented as vectors, and the angle and length between them are calculated to determine the user's target movement direction and target movement distance. For example, when the line connecting the vectors of the initial position and the target movement position is detected to be 30 degrees to the left relative to the horizontal line of the RV, the predicted target movement direction of the user on the electric lifting bed is 30 degrees to the left relative to the horizontal line of the RV. In a practical application scenario, when the RV is driving on a left curve, the user's target movement direction is to the right.

[0136] 403. The electric lifting bed includes a frame. When the RV is in a curved position, the target area of ​​the frame is controlled to protrude to prevent the user from moving in the target direction. The target area is the area in the frame corresponding to the target direction of movement.

[0137] The motorhome's electric lift bed 101 includes a frame 103, which is a movable frame. Specifically, when the motorhome goes around a curve, the user may move in the opposite direction of the curve due to inertia, potentially falling off the electric lift bed. To prevent this, a target area of ​​the frame can be determined based on the user's intended direction of movement. This target area corresponds to the intended direction of movement. When it is predicted that the user may move in the intended direction, the target area of ​​the frame is raised to provide more support, thus preventing the user from moving in that direction and protecting the user's safety.

[0138] In some embodiments, the motorhome's electrically adjustable bed is also equipped with a mattress. When it is predicted that the user may move in the target direction, the target area of ​​the mattress is controlled to bulge out to prevent the user from moving in the target direction.

[0139] As an optional embodiment, when a user is detected on the electric lifting bed, the method further includes:

[0140] Receive sleep / wake commands sent by user equipment;

[0141] In response to the sleep wake-up command, the target position of the electric lifting bed frame is raised to wake the user.

[0142] In one of the above optional embodiments, the electric lift bed 101 of the RV includes a communication module, which supports establishing a wired communication connection or a wireless communication connection with a user device. The user device can send a sleep wake-up command to the electric lift bed. The sleep wake-up command can be generated by the user device when it detects that the current time has reached a preset wake-up time, or it can be generated by the user device detecting a wake-up operation input by the user. The target position of the frame can be preset by the user in advance. For example, the position of the frame corresponding to the user's legs can be used as the target position. When a sleep wake-up command is received, the target position of the frame corresponding to the user's legs can be raised to wake up the user.

[0143] In one of the above optional embodiments, when a user is detected to be asleep on the electric lifting bed, the target position of the keel frame of the electric lifting bed can be raised according to the sleep wake-up command, so as to wake up the user sleeping on the electric lifting bed, thereby enabling the electric lifting bed to have a sleep wake-up function.

[0144] As can be seen, by implementing the embodiments of this application, when the RV enters a curve, the target area of ​​the electric lifting bed's frame can be raised to prevent the user from moving in the target direction, thereby ensuring the user's safety. By establishing the correspondence between the curve position, curve direction, lane type, and movement position, the user's target movement position and direction can be predicted more accurately, improving the user's safety when using the electric lifting bed.

[0145] Please see Figure 5 This is a flowchart illustrating the fourth embodiment of a control method for an electric lift bed in a motorhome disclosed in this application. Figure 5 The method shown includes the following implementation steps:

[0146] 501. Obtain the driving data of the RV, wherein the driving data is at least one of the following: mileage information, driving speed, road conditions, and number of starts and stops of the RV, and the road conditions include the location of curves in the driving path, the direction of the curves, and the lane type of the driving path.

[0147] For details on step 501, please refer to the relevant descriptions in steps 201 and 301 in the aforementioned embodiments, which will not be repeated here.

[0148] 502. Based on the curve location, the curve direction, and the lane type, predict the target movement direction of the user on the electric lifting bed.

[0149] For details on step 502, please refer to the relevant description in step 402 of the aforementioned embodiments, which will not be repeated here.

[0150] 503. Based on the user's current position on the electric lifting bed and the target direction of movement, determine that the user is about to move outside the electric lifting bed.

[0151] In this embodiment of the application, after predicting the target movement direction of the user on the electric lifting bed based on the curve location, curve direction, and lane type, the method may further include the following steps:

[0152] Determine the user's target movement position based on the user's current position on the electric lifting bed and the target movement direction;

[0153] Determine whether the user's target movement location is within the safe area of ​​the electric lifting bed;

[0154] If the user's target location is not within the safe zone, it is determined that the user is about to move outside the electric lifting bed.

[0155] The safety zone of the electric lift bed can be preset according to the location, direction, and type of curve. For example, when the RV is not in a curve, the area within 10cm of the edge of the electric lift bed is considered the safety zone; when the RV is in a curve, the area within 20cm of the edge of the electric lift bed is considered the safety zone. When the RV reaches a curve, if the user is detected to be outside the safety zone, it is determined that the user is about to move outside the electric lift bed, and a risk of falling is identified.

[0156] 504. The electric lifting bed also includes folding wings, which unfold to correspond to the direction of movement of the target.

[0157] The motorhome's electric lift bed 101 includes a folding wing 104. The folding wing can be installed at a location where the electric lift bed is not connected to the interior wall of the motorhome. The folding wing can be freely unfolded or folded. When not in use, the folding wing is folded. When it detects that a user is about to move outside the electric lift bed, it automatically unfolds to protect the user. For example, when the motorhome is going around a curve, the user may move in the opposite direction of the curve due to inertia, potentially falling off the electric lift bed. To prevent this, when the motorhome reaches a curve, if it detects that the user's target movement position is at the edge of the electric lift bed and the user is only 10cm away from the edge, it is determined that the user is outside the safe zone and is about to move outside the electric lift bed. Based on the user's target movement direction, the folding wing corresponding to that direction unfolds to provide more support and prevent the user from moving in that direction, thus protecting the user's safety.

[0158] As can be seen, by implementing the embodiments of this application, when the RV enters a curve, the folding wings of the electric lifting bed can be unfolded to prevent the user from moving in the target direction, which can effectively protect the user's safety and improve the safety of using the electric lifting bed.

[0159] Please see Figure 6 This is a flowchart illustrating the fifth embodiment of a control method for an electric lift bed in a motorhome disclosed in this application. Figure 6 The method shown includes the following implementation steps:

[0160] 601. Obtain the driving data of the RV, wherein the driving data is at least one of the following: mileage information, driving speed, road conditions, and number of starts and stops of the RV, and the road conditions include the location of the target building, wherein the target building is a building that can block the RV.

[0161] In this embodiment of the application, the driving conditions include the location of the target building. The target building is a building that can block the light inside the RV. The target building is a tunnel, a super high-rise building, or other building that blocks the light inside the RV. This is not limited to any particular type of building.

[0162] For further details regarding step 601, please refer to the relevant descriptions in step 201 of the foregoing embodiments; they will not be repeated here.

[0163] 602. Detect whether there is a user in the target area of ​​the electric lifting bed, where the target area is the space between the electric lifting bed and the floor of the RV. If yes, proceed to steps 603 to 608; if no, proceed to steps 605 to 608.

[0164] In this embodiment, the RV is equipped with a camera and a recognition device. The camera can capture images of the target area of ​​the electric lift bed, or other image acquisition devices can be used to acquire images of the target area; no limitation is made here. The camera sends the captured image of the target area to the recognition device, which identifies whether a user exists within the target area. The target area can be any area within the RV that the user has pre-selected.

[0165] 603. Obtain the user's gesture actions.

[0166] In this embodiment of the application, after identifying the presence of a user within the target area of ​​the electric lifting bed, further:

[0167] Preprocess the image of the target region;

[0168] Acquire gesture images from the target region image;

[0169] Extract features from gesture images;

[0170] Recognize the features of gesture images to obtain the user's gesture actions.

[0171] In the above embodiments, preprocessing of the target region image, including image denoising and edge detection, can improve the accuracy of user gesture recognition; then, a gesture image is obtained from the target region image, and features of the gesture image are extracted, including finger posture and finger movement trajectory; finally, the features of the gesture image are identified to obtain the user's gesture.

[0172] 604. Control the electric lifting bed to rise or fall according to the user's gestures.

[0173] In this embodiment, the user's hand gestures can be identified by a recognition device, and the electric lifting bed can be controlled to rise or fall based on the user's hand gestures. The hand gestures can be preset by the user. For example, a user's hand gesture of pointing upwards or making a fist represents controlling the electric lifting bed to rise, while a user's hand gesture of pointing downwards or spreading all five fingers represents controlling the electric lifting bed to fall. Users can personalize their hand gestures according to their usage habits and ease of operation, which is not limited here.

[0174] In some embodiments, when a user wants to use the electric lifting bed, the electric lifting bed can also be controlled by a physical control device. The user can operate the control device to control the electric lifting bed to descend to a suitable height. After descending to a suitable height, the user can use the electric lifting bed to rest or sleep.

[0175] The electric lifting bed is equipped with several pressure sensors, and the arrangement of these pressure sensors is not limited; for example, they can be arranged in a uniform strip. Accordingly, this application can utilize the pressure sensors arranged on the electric lifting bed to detect whether a user is currently using the electric lifting bed, i.e., whether a user is present on the electric lifting bed. If the pressure value detected by the pressure sensor is greater than a preset pressure, it can be determined that a user is present on the electric lifting bed. Otherwise, it is determined that no user is present on the electric lifting bed.

[0176] As an optional implementation, when the presence of a user on the electric lifting bed is detected, the following solutions may also be included:

[0177] Acquire the pressure sensor data of the electric lifting bed;

[0178] The user's posture is determined based on the pressure sensor data;

[0179] Identify whether the user's posture is a preset wake-up posture;

[0180] If the user's posture is the preset getting-up posture, control the electric lifting bed to descend.

[0181] In one of the above optional embodiments, the user can preset a mapping relationship between pressure sensor data and user posture. When the acquired pressure sensor data matches the preset getting-out posture, the electric lifting bed is controlled to descend to a suitable height, allowing the user to get out of bed safely and smoothly. The mapping relationship between pressure sensor data and user posture can be determined based on the user's getting-out posture in historical user getting-out actions and the corresponding pressure sensor data. For example, when a user gets out of bed, the pressure value at the elbow position will be greater than the pressure value during sleep. When the pressure value at the elbow position is detected to be greater than the preset pressure, it can be determined that a user is getting out of bed. This is not limited to this.

[0182] By adopting one of the above optional implementation methods, it is possible to automatically determine whether the user wants to get up and control the electric lifting bed to descend automatically, eliminating the need for the user to control the descent of the electric lifting bed through gesture recognition or operation of physical control devices, thereby improving the automation level of the electric lifting bed and the user experience.

[0183] As another optional implementation, when the presence of a user on the electric lifting bed is detected, the following scheme may also be included:

[0184] Obtain the user's physiological data;

[0185] Based on the physiological data, the user's physical condition is determined;

[0186] Detect whether the user's physical condition matches preset physical condition characteristics;

[0187] If the conditions are met, a notification message will be sent to the RV driver.

[0188] In another optional embodiment described above, the method of acquiring the physiological data is not limited; for example, it can be collected through a wearable device worn by the user. The physiological data refers to data describing the user's human characteristics, which may include, but is not limited to, heart rate, pulse, respiration, blood pressure, or other physiological data.

[0189] In another optional implementation described above, the physiological data can be analyzed to determine the user's current physical condition, and further, by detecting and analyzing whether the user's current physical condition meets preset physical condition characteristics, it can be determined whether the user's physical condition requires timely medical attention. The preset physical condition characteristics may include characteristics such as high blood pressure and stroke.

[0190] In another optional embodiment described above, when the user's current physical condition is detected to match preset physical condition characteristics, a prompt message is sent to the RV driver. The prompt message may include information such as reminding the RV driver of the user's physical condition on the electric lift bed, or reminding the RV driver to change the RV's driving route. The prompt message can be delivered via voice broadcast or SMS, and is not limited thereto. In some embodiments, the electric lift bed is also equipped with a control device that can automatically control the RV navigation system to change the navigation route when the user's current physical condition is detected to match preset physical condition characteristics. The driving route is a route to the nearest hospital, and the RV driver can follow the navigation route to the nearest hospital.

[0191] Alternatively, by acquiring the physiological data of the user on the electric lifting bed, the user's physical condition can be assessed in a timely manner. When the user is detected to be unwell, the RV driver can be notified immediately or the navigation route can be automatically switched to the nearest hospital, thus ensuring the user's safety.

[0192] 605. Detect whether the electric lifting bed is in an ascending or descending state.

[0193] In this embodiment of the application, after controlling the electric lifting bed to rise or fall, the state of the electric lifting bed can be automatically detected. The state includes rising or falling, which is not limited here.

[0194] 606. The electric lifting bed is equipped with a lighting device on the side facing the RV floor. When the electric lifting bed is in the rising state, the lighting device is controlled to be turned on.

[0195] The motorhome's electric lift bed 101 includes a lighting device 105. This lighting device can be installed on the side of the electric lift bed facing the motorhome floor, i.e., at the bottom of the electric lift bed, which is not limited here. If the electric lift bed is detected to be in an ascending state, the lighting device is controlled to be turned on; if the electric lift bed is detected to be in a descending state, the lighting device is controlled to be turned off. In this embodiment, when the electric lift bed is in an ascending state, it indicates that the user wants to perform other activities in the space under the electric lift bed, therefore the lighting device is turned on; when the electric lift bed is in a descending state, it indicates that the user has finished other activities in the space under the electric lift bed and wants to use the electric lift bed, therefore the lighting device is controlled to be turned off.

[0196] 607. Determine whether the current driving position of the RV has reached the location of the target building.

[0197] In this embodiment of the application, after the lighting device is turned on, the method further includes: determining whether the current driving position of the RV has reached the position of the target building. The target building is a building that can block the light from the RV, such as a tunnel, a high-rise building, etc., which are not limited here.

[0198] In some embodiments, the location of the RV can be determined by detecting the light intensity inside the RV. For example, when the light intensity inside the RV is detected to be lower than a preset light intensity, it indicates that the RV has reached the target building. The preset light intensity is the light intensity required for normal activities inside the RV. Alternatively, the location of the target building can be preset in the navigation system. The navigation system can then determine whether the RV has reached the preset target building location. For example, the user can preset multiple target locations along the route to the target building in the navigation system. When the RV travels to the target location according to the navigation system, it indicates that the RV has reached the target building.

[0199] 608. When the RV reaches the location of the target building from its current driving position, increase the brightness of the lighting device.

[0200] In this embodiment, when the RV's current driving position is determined to have reached the target building, it is detected whether the light intensity inside the RV is lower than a preset light intensity. If the light intensity inside the RV is lower than the preset light intensity, the brightness of the lighting device is increased. Automatically controlling the brightness of the lighting device by detecting the light intensity inside the RV can improve the user experience. Furthermore, when the light intensity inside the RV is too low, it can affect the driver's vision, thereby affecting driving safety. Therefore, this embodiment can also improve the driving safety of the RV driver.

[0201] As can be seen, by implementing the embodiments of this application, users can control the electric lifting bed to rise or fall using gestures, improving the ease of use of the electric lifting bed. The lighting device can be turned on and off by controlling the status of the electric lifting bed, improving the flexibility and convenience of lighting control. Furthermore, when the electric lifting bed is detected to be in a descending state, the lighting device is automatically turned off, saving electricity consumption in the RV. When the light inside the RV is blocked, the brightness of the lighting device can be automatically increased, improving the user experience.

[0202] Based on the foregoing embodiments, this application discloses a control system for an electric lift bed in a motorhome. The system includes various modules and units included in each module, which can be implemented by a processor; of course, it can also be implemented by specific logic circuits. In the implementation process, the processor can be a central processing unit (CPU), microprocessor (MPU), digital signal processor (DSP), or field programmable gate array (FPGA), etc.

[0203] Please see Figure 7 , Figure 7 This is a schematic diagram of the control system for an electric lift bed in a motorhome, as disclosed in an embodiment of this application. Figure 7As shown, the control system for the electric lift bed in a motorhome includes: an acquisition module 701, a determination module 702, and a response module 703, wherein:

[0204] The acquisition module 701 is used to acquire the driving data of the RV and the usage data of the electric lift bed of the RV. The driving data includes at least one of the mileage information, driving speed, driving road conditions, and number of start-stop times of the RV. The usage data includes the usage time of the electric lift bed, the number of times it jams during use, and the number of times the lifting position fails to reach the preset position.

[0205] The determining module 702 is used to determine the maintenance requirements for the electric lifting bed based on the driving data and the usage data.
