Description

Technical Field

[0001] One or more embodiments of this application relate to the automotive field, and more particularly to a control method, device, and electronic device for assisting vehicle door opening. Background Technology

[0002] As people's living standards improve, cars have become an indispensable part of daily life. Users frequently need to open and close car doors. Because different users have different strengths, the effort required to open the same car door varies. Similarly, the weight of car doors differs between vehicles, so the effort required for the same user to open different doors also varies. For vehicles with heavier doors or for drivers and passengers with less strength, the difficulty in opening the door results in a poor driving experience.

[0003] In related technologies, a fixed amount of door-opening assistance is provided to reduce the pressure on users when opening the car door. However, different users have different needs for the same door-opening assistance. If the fixed assistance is greater than the user's needs, the user may be injured due to excessive force without warning; if the fixed assistance is less than the user's needs, the user will have to expend more effort to open the door. Therefore, how to provide users with appropriate door-opening assistance is an urgent problem to be solved. Summary of the Invention

[0004] This application provides a control method, device, and electronic device for assisting vehicle door opening, in order to address the shortcomings of related technologies.

[0006] Acquire user information to characterize the moment a user pulls the car door handle, the user information including a first posture and a first facial expression;

[0007] Based on the user information, a first force matching the first posture and the first facial expression is retrieved from a preset door opening assistance information database;

[0008] Based on the first force, the door corresponding to the door handle is assisted in opening.

[0009] Optionally, the user information may also include the user's physical and / or mental state.

[0010] Optionally, the user information may also include the user's identity.

[0011] Optionally, the method further includes: when the user's identity changes, querying the changed first force from the preset door opening assistance information database according to the changed user information, the changed user information including the changed user's identity; and adjusting the door opening assistance applied to the car door based on the changed first force.

[0012] Optionally, the method further includes: obtaining the pulling force exerted by the user on the door handle; adjusting the first force in real time according to the real-time pulling force, wherein the sum of the first force and the real-time pulling force is equal to the target force for opening the door.

[0013] Optionally, the method further includes: if the first force is not found, obtaining the user's vital signs information; retrieving a second force from a cloud database that matches the vital signs information and the user information, the cloud database storing forces that match the vital signs information and user information of other users; applying door opening assistance to the car door based on the second force, and storing the matching relationship between the second force and the user information in the preset door opening assistance information database.

[0014] Optionally, the method further includes: after implementing the door opening assistance, acquiring the user's second posture and second facial expression at the moment the car door opens; if the similarity between the second posture and a preset posture is greater than the similarity between the first posture and the preset posture, then updating the matching relationship between the first force and the user information in the preset door opening assistance information database according to the second posture; and / or, if the similarity between the second facial expression and a preset expression is greater than the similarity between the first facial expression and the preset expression, then updating the matching relationship between the first force and the user information in the preset door opening assistance information database according to the second facial expression.

[0015] According to a second aspect of one or more embodiments of this application, a control device for assisting in opening a vehicle door is provided, the device comprising:

[0016] The acquisition module is used to acquire user information that characterizes the moment a user pulls the car door handle, the user information including a first posture and a first facial expression;

[0017] The query module is used to query the first force that matches the first posture and the first facial expression from the preset door opening assistance information database based on the user information;

[0018] The implementation module is used to provide door opening assistance to the door corresponding to the door handle based on the first force.

[0019] According to a third aspect of one or more embodiments of this application, an electronic device is provided, comprising:

[0020] processor;

[0021] Memory used to store processor-executable instructions;

[0022] The processor executes the executable instructions to implement the method described in the embodiments of the first aspect above.

[0023] According to a fourth aspect of one or more embodiments of this application, a computer-readable storage medium is provided that stores computer instructions thereon, which, when executed by a processor, implement the steps of the method as described in the embodiments of the first aspect above.

[0024] As can be seen from the above technical solutions, in one or more embodiments of this application, by acquiring the user's first posture and first facial expression at the moment of pulling the car door handle, and then querying a first force matching the first posture and first facial expression from a preset door opening assistance information database, door opening assistance is applied to the car door according to the first force. Since the user's first posture and first facial expression are a kind of momentum estimation, representing the magnitude of the force the user expects to apply to the car door handle in order to open the car door, the first force obtained by querying the first force matching the first posture and first facial expression can be very close to the user's current need for door opening assistance. When door opening assistance is applied based on the first force, the user can easily open the car door according to the door opening assistance and the force they expect to apply, so that the user will not have to exert effort to open the door due to insufficient door opening assistance, nor will the user be injured when opening the door due to excessive door opening assistance.

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0033] It should be noted that the steps of the corresponding methods in other embodiments are not necessarily performed in the order shown and described in this application. In some other embodiments, the methods may include more or fewer steps than those described in this application. Furthermore, a single step described in this application may be broken down into multiple steps in other embodiments; and multiple steps described in this application may be combined into a single step in other embodiments.

[0034] The following describes one or more embodiments of this application in detail.

[0035] Figure 1 This is a flowchart illustrating a control method for assisting vehicle door opening, as provided in an exemplary embodiment. Figure 1 As shown, the method may include the following steps:

[0036] S101. Obtain user information to characterize the moment a user pulls the door handle, the user information including a first posture and a first facial expression.

[0037] User information is used to indicate the characteristics of the user currently opening the door. Since different users exert different amounts of force when pulling the same car door, and the same user exerts different amounts of force when pulling different doors, user information can accurately determine the characteristics of the user opening the door, helping to provide appropriate door-opening assistance based on these characteristics. The entire process of a user opening a car door can be divided into three stages: touching the door handle, pulling the door handle, and opening the door. Because sometimes users touch the door handle not to open the door, but simply by accident, the user information obtained is the information at the moment the door handle is pulled, not the information at the moment of touching the door handle.

[0038] User information includes the user's initial posture and initial facial expression. The initial posture refers to the user's posture at the moment of pulling the door handle, and this posture is related to the angle of force applied by the user when opening the door. In this embodiment, the distances from the user's hand to their elbow, elbow to their shoulder, and shoulder to the edge of the vehicle can be obtained using radar. Then, the angle of force applied by the user is calculated based on a trigonometric function of these three distances, and the user's initial posture is determined based on this angle. Of course, other methods can also be used to determine the user's initial posture, and this application does not limit this.

[0039] Figure 2 This is a schematic diagram illustrating two first postures provided in an exemplary embodiment. For example... Figure 2 As shown, when a user's door-opening posture involves the lower body remaining upright while the upper body leans approximately 15 degrees towards the car body and pulls on the door, it indicates a relatively small pulling force, which can be considered the normal door-opening posture. Conversely, when the user's door-opening posture involves leaning the entire body away from the car body and pulling outwards, it indicates a larger pulling force, which can be considered the force exerted by the user to open the door. Therefore, the user's initial posture indicates the expected pulling force applied to the door handle to open the car door.

[0040] Similarly, the first facial expression can also indicate the pulling force the user expects to apply to the door handle. A gentle and calm first facial expression, such as no facial features being squeezed and a slight upturn of the corners of the mouth, indicates that the user expects to apply a smaller pulling force; a more grimacing first facial expression, such as the user frowning and facial features being squeezed together, indicates that the user expects to apply a larger pulling force. In this embodiment, an image of the user's facial expression at the moment of pulling the door handle can be captured by a camera, and then the features of the facial expression image can be extracted and analyzed to determine the first facial expression. Alternatively, other methods in related technologies can also be used to determine the first facial expression, and this application does not limit this method.

[0041] S102. Based on the user information, query the preset door opening assistance information database for a first force that matches the first posture and the first facial expression.

[0042] The preset door opening assistance information database stores various preset matching relationships, which are the matching relationships between the assistance force and the user's door opening posture and facial expression. Generally, for the same car door, when the user's door opening posture and facial expression indicate a relatively small pulling force, the matched assistance force will be relatively large. When the user's door opening posture and facial expression indicate a large pulling force, the matched assistance force will be relatively small. For example, assuming a car door A requires a target force of 20 Newtons to open, then when the user's door opening posture is the normal posture described above, and the user's facial expression is relatively gentle and calm (i.e., the user expects to apply a small pulling force), the matched assistance force can be 15 Newtons (more than 1 / 2 of the target force). If the user's door opening posture is the forceful posture described above, and the user's facial expression is relatively fierce (i.e., the user expects to apply a large pulling force), the matched assistance force can be 8 Newtons (less than 1 / 2 of the target force). The specific preset value of the assistance force can be set by those skilled in the art, and this application does not impose any restrictions on this.

[0043] Each vehicle can have its own proprietary preset assist information database, which stores only the door opening assist information for each door of the current vehicle. This database can be deployed locally on the vehicle's processor. After obtaining user information, the processor can perform a local query to obtain the initial assist force matching the first posture and facial expression. Alternatively, the database can be deployed in the cloud. After obtaining user information, the vehicle uploads it to the cloud, where the cloud queries the preset assist information database to obtain the matching initial assist force.

[0044] S103. Apply door opening assistance to the door corresponding to the door handle based on the first force.

[0045] After obtaining the initial force, an opening assistance is applied to the door corresponding to the door handle based on this initial force. This allows the user to open the door using this opening assistance and the pulling force the user expects to apply to the door handle. Since the initial force is determined by matching the user's initial posture and facial expression at the moment of pulling the door handle, this initial force will perfectly match the user's current need for door opening assistance. Therefore, applying the opening assistance based on the initial force helps the user open the door easily, preventing injury due to excessive assistance or requiring excessive force. Furthermore, this solution can provide suitable opening assistance for different users opening the same door, and can also provide different opening assistance for different doors for the same user, effectively improving the ease of opening car doors.

[0046] In one embodiment, user information also includes the user's physical and / or mental state. A user's physical state affects the amount of force they can use to open a door. For example, after strenuous exercise, a user is usually fatigued and can use less force to open the door. Conversely, after replenishing energy (e.g., after a meal), a user is usually in a better physical state and can use more force to open the door. Physical and mental state are often closely related. When a user is in a good mental state (e.g., happy, joyful), their physical state is relatively better, allowing them to use more force to open the door; conversely, when in a poor mental state (e.g., depressed, sad), their physical state is also poor, and they can use less force to open the door.

[0047] Therefore, based on the first posture, the first facial expression, and the user's physical and / or mental state, a first force matching the user's current door-opening assistance needs can be queried, thereby further improving the accuracy of the queried first force and providing the user with more suitable door-opening assistance, reducing the effort required for the user to open the door. Specifically, the user's physical state can be obtained from the user's exercise records (such as step count records, sports venue visit records, etc.), restaurant order records, etc., and the user's mental state can be obtained from the user's vital signs information (such as heart rate), facial expressions, etc. The above acquisition methods are only examples, and this application does not limit the specific methods for acquiring the user's physical and / or mental state.

[0048] In one embodiment, the user information also includes the user's identity. Different users have natural differences in physical strength, and even when opening a car door with the same posture and facial expression, their needs for door opening assistance are not entirely the same. For example, when male user A and female user B try to open the same car door with the same posture and facial expression, user A exerts more force on the door handle than user B, therefore user A requires less door opening assistance than user B. Therefore, obtaining the user's identity helps to determine a more suitable initial force based on the user's identity, initial posture, and initial facial expression, thereby providing the user with more appropriate door opening assistance.

[0049] In one embodiment, user information changes accordingly when the user's identity changes. For example, user A leaves the car after receiving a phone call the moment they pull the door handle, and user B then pulls the door handle. At this time, the user identity contained in the user information changes. Furthermore, since the first posture and first facial expression of two users pulling the door handle are usually not the same, when user A changes to user B pulling the door handle, the user identity, the first posture, and the first facial expression generally change. Since a first force has been matched based on user A's user information, but this first force is not suitable for user B, it is necessary to re-acquire the changed user information and query the preset assistance information database for the changed first force to adjust the door opening assistance based on the changed first force.

[0050] In this embodiment, by promptly obtaining the changed user information when the user's identity changes, it is helpful to provide more accurate and appropriate door opening assistance to the user currently pulling the door handle based on the changed user information, thereby meeting the door opening assistance needs of different users and improving the user's car use experience.

[0051] In one embodiment, the real-time pulling force of the user on the door handle can also be obtained, and the first force can be adjusted in real time based on this real-time pulling force. Since the user's first posture and first facial expression at the moment of pulling the door handle represent the pulling force that the user expects to apply to the door handle, it is an estimate. However, the actual pulling force applied by the user to the door handle may differ from the estimate. Therefore, the first force obtained based on the estimate may also differ from the user's current need for force to assist opening the door.

[0052] In this embodiment, after obtaining the first force based on the first posture and the first facial expression, since the sum of the first force and the user's real-time pulling force equals the target force for opening the car door, the first force can be adjusted by obtaining the user's real-time pulling force on the door handle, so that the first force can better match the user's need for door opening assistance. For example, assuming the target force for opening car door a is 16 Newtons, and the first force obtained based on the user's first posture and the first facial expression is 10 Newtons, it means that the user expects to apply a force of 6 Newtons to the door handle. If the pressure sensor installed on the door handle obtains that the user applies a real-time force of 8 Newtons to the door handle, in this case, if 10 Newtons of door opening assistance is still applied to the door, the door opening assistance and the user's real-time pulling force will exceed the target force. In this case, the user will be pushed back or even injured when opening the door due to excessive door opening assistance. Therefore, adjusting the value of the first force to 8 Newtons based on the real-time pulling force helps the user open the car door easily and safely.

[0053] In one embodiment, if a user is opening a car door for the first time, the preset door opening assistance information database may not store a first force matching the user's information. In this case, the user's vital signs information can be obtained. Vital signs information may include age, gender, height, weight, etc. For example, facial recognition technology can be used to obtain the user's vital signs information. Then, based on the vital signs information, a second force matching the user's vital signs and information can be retrieved from a cloud database. For instance, a search request can be sent to the cloud database, carrying the user's vital signs and information. The cloud database then responds to the search request, retrieves the matching second force, and returns the second force to the corresponding vehicle. The cloud database stores a large amount of user vital signs information, user information, and matching forces using big data technology. Since users with similar or identical vital signs have similar or even identical needs for door opening assistance force, a more suitable second force can be obtained from other users' data based on their vital signs and user information. Applying this second force to the car door helps the user open the door easily.

[0054] It should be noted that the user's vital signs information, user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this manual are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of related data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and corresponding operation portals are provided for users to choose to authorize or refuse.

[0055] After implementing door opening assistance based on the second force, the matching relationship between the second force and the current user's information can be stored in a preset door opening assistance information database. This way, when the user opens the same door again, the system can directly retrieve the matching first force from the preset door opening assistance information database based on the stored matching relationship. This reduces the time the vehicle spends requesting retrieval from the cloud database and waiting for a response, thus improving the efficiency of door opening assistance implementation.

[0056] In one embodiment, after implementing door opening assistance, the user's second posture and second facial expression at the moment the door opens can also be acquired. Then, the similarity between the second posture and a preset posture, as well as the similarity between the first posture and the preset posture, are calculated. The preset posture is the posture that the user feels most comfortable in when opening the door. The higher the similarity between the user's posture when pulling the door handle and the preset posture, the higher the user's comfort level. Therefore, when the similarity between the second posture and the preset posture is greater than the similarity between the first posture and the preset posture, the matching relationship between the first force and user information in the preset door opening assistance information database can be updated based on the second posture. This ensures that the first force can only be matched when the user pulls the door handle in the second posture, thus making the implemented door opening assistance closer to the optimal force required by the user, helping the user open the door in a more comfortable posture.

[0057] Similarly, the similarity between the second facial expression and the preset expression, as well as the similarity between the first facial expression and the preset expression, can be calculated. The preset expression is the facial expression that the user feels most comfortable displaying when opening the car door. The higher the similarity between the user's facial expression when pulling the door handle and the preset expression, the higher the user's comfort level. Therefore, when the similarity between the second facial expression and the preset expression is greater than the similarity between the first facial expression and the preset expression, the matching relationship between the first force and user information in the preset door opening assistance information database can be updated based on the second facial expression.

[0058] The preset poses and preset expressions can be set by those skilled in the art, and the process of calculating similarity can refer to the relevant content of image similarity calculation in the prior art. This application does not impose any restrictions on this.

[0059] In this embodiment, by continuously updating the matching relationship between the force and user information in the preset door opening assistance information database, it helps to provide the best door opening assistance to the user and improve the user's car use experience.

[0060] Figure 3 This is a schematic diagram of the architecture of a vehicle door opening assistance control system provided in an exemplary embodiment. Figure 3 As shown, the system includes a door motor 304, a door motor control unit 305, a door motor independent battery 306, a door handle control unit 307, a camera 308, a camera processing unit 309, a body processor 310, and a body battery 311. The door motor 304 is connected to the door 301 via a door hinge 304a. The door handle control unit 307 is connected to the door handle 302 and is used to detect the pulling force applied by the user to the door handle 302. The camera 308 is mounted on a pillar 303 between the front and rear doors. The door motor independent battery 306 activates when the vehicle's power is depleted to ensure that the door can provide door opening assistance.

[0061] When a user pulls the door handle 302, the camera 308 begins to acquire the user's first posture and first facial expression, and transmits the acquired image to the camera processing unit 309 for image analysis. The camera processing unit 309 then transmits the analysis result to the body processor 310. Alternatively, the camera processing unit 309 can be located within the body processor 310, allowing the body processor 310 to perform the image analysis. Based on the analysis result, the body processor 310 queries a preset door opening assistance information database for a first force matching the first posture and first facial expression, and generates a corresponding force command based on the found first force. The body processor 310 then transmits the force command to the door motor control unit 305. Upon receiving the force command, the door motor control unit 305, in response to the force command, controls the door motor 304 to provide corresponding door opening assistance to the door 301, enabling the user to open the door with the assistance.

[0062] In addition, the door handle control unit 307 is used to acquire the user's real-time pulling force and transmit the acquired real-time pulling force information to the body processor 310. The body processor 310 regenerates the first force command based on the real-time pulling force information and the target force for opening the door, and sends the newly generated force command to the door motor control unit 305, so that the door motor control unit 305 controls the door motor 304 to adjust the door opening assistance provided to the door 301.

[0063] Similar to the above, when a user opens the car door, in order to improve the ease of closing the door, the camera 308 can also capture the user's posture and facial expression at the moment of pulling the door handle. Then, based on the posture and facial expression, the camera can retrieve the matching closing force from the preset door closing assistance information database and apply the corresponding closing assistance to the door based on the closing force.
