Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a method, apparatus, vehicle, and storage medium for personalizing vehicle settings. Background Technology

[0002] With the development and advancement of technology, users have increasingly demanded personalized features for their vehicles. Therefore, to meet these personalized needs, vehicle functions are becoming increasingly intelligent, such as intelligent voice assistants and smart keys. A smart key allows users to enter the vehicle without a physical key, providing them with greater convenience.

[0003] In this technology, when a user wants to enter a vehicle, they first touch the door handle. Upon detecting this touch, the vehicle's low-frequency antenna emits low-frequency signals to locate a legitimate key. Upon receiving a high-frequency signal from the legitimate key, the vehicle unlocks. Furthermore, the high-frequency signal emitted by the legitimate key may carry a key ID (Identity Document), which the vehicle can then use to configure various in-vehicle devices to the preferences corresponding to the key ID after the user enters the vehicle.

[0004] However, in the above method, if there are other low-frequency signals in the surrounding environment, they will interfere with the transmission of the key ID, resulting in incorrect key ID transmission. In this case, it will be impossible to make accurate preference settings for each vehicle device. Summary of the Invention

[0005] This application provides a method, device, vehicle, and storage medium for personalized vehicle settings, which can accurately personalize the in-vehicle infotainment system, thereby improving the user experience. The technical solution is as follows:

[0006] Firstly, a method for personalizing vehicle settings is provided, the method comprising:

[0007] When it is detected that any front door of the target vehicle changes from closed to open, the key identifier of the first key is acquired at a first frequency, wherein the first key is the key that is near the front door.

[0008] If a person is detected in the target seat of the target vehicle, the key identifier of the second key is acquired at the first frequency, wherein the second key is the key that is close to the central control screen of the target vehicle;

[0009] If the key identifier of the first key and the key identifier of the second key are the same, the vehicle's infotainment system is personalized based on the key identifier of the first key.

[0010] In this application, when it is detected that any front door of the target vehicle changes from a closed state to an open state, the key identifier of the first key is acquired at a first frequency. Then, when it is detected that someone is in the target seat of the target vehicle, the key identifier of the second key is acquired at the first frequency. Finally, if the key identifiers of the first key and the second key are the same, the vehicle's infotainment system is personalized based on the key identifier of the first key. Thus, by acquiring the key identifiers of the first key and the second key under different behavioral scenarios and determining whether the key identifiers acquired under different behavioral scenarios are the same, and then, if the key identifiers of the first key and the second key are the same under different behavioral scenarios (i.e., the keys belong to the same user under different behavioral scenarios), the vehicle's infotainment system is personalized based on the key identifiers. This accurately achieves personalized settings for the infotainment system, ensuring that the personalized settings meet the current user's needs, thereby improving the user experience.

[0076] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0077] It should be understood that "multiple" as mentioned in this application refers to two or more. In the description of this application, unless otherwise stated, " / " indicates "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist, for example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and that "first," "second," etc., do not necessarily imply differences.

[0078] First, the principle of keyless entry vehicles involved in the embodiments of this application will be explained.

[0079] Nowadays, most vehicles are equipped with smart keys, which can unlock and start the vehicle without keys, providing great convenience for unlocking and driving the vehicle.

[0080] Typically, vehicles are equipped with multiple low-frequency antennas, which are distributed in different locations within the vehicle. For example, Figure 1 This is a schematic diagram of the distribution of vehicle antennas. (See attached image) Figure 1 , Figure 1 It includes vehicle 101, on which multiple low-frequency antennas 102 are mounted.

[0081] The multiple low-frequency antennas 102 are distributed at different locations on the vehicle 101. For example... Figure 1 As shown, the multiple low-frequency antennas 102 can be arranged at the two front doors of the vehicle 101 (low-frequency antenna 4 and low-frequency antenna 5), ​​the central control screen (low-frequency antenna 1), the sunroof (low-frequency antenna 2), the rear seats (low-frequency antenna 3), and the trunk (low-frequency antenna 6).

[0082] When keyless entry is attempted, upon detecting a touch on the door handle of vehicle 101, multiple low-frequency antennas 101 sequentially emit radio frequency signals of a certain frequency around vehicle 101 to locate the key. Upon receiving the radio frequency signals, the key of vehicle 101 can emit high-frequency signals to indicate its presence. When the vehicle's body control system receives the high-frequency signal emitted by the key, it can confirm the presence of a key in the vicinity of vehicle 101. Furthermore, the high-frequency signal emitted by the key can carry a key ID and a key symbol (SK), which can be used to verify whether the key identified by the key ID is the key equipped with vehicle 101. Finally, if a key is present in the vicinity of vehicle 101, and the present key is the key equipped with vehicle 101, vehicle 101 can be unlocked, thus achieving keyless vehicle unlocking.

[0083] Before describing the vehicle personalization setting method provided in the embodiments of this application, the application scenarios of the embodiments of this application will be explained first.

[0084] In the aforementioned keyless entry method, if other interference signals exist in the surrounding environment, these signals will interfere with the process of locating the key for vehicle 101 and affect the accurate transmission of the key ID. For example, if there are two keys around vehicle 101, located at the left front door and the right rear door respectively, the vehicle's infotainment system should ideally be configured based on the key ID of the key at the left front door. However, due to the presence of interference signals, it might be mistakenly interpreted as being configured based on the key ID of the key at the right rear door. Consequently, accurate preference settings for the vehicle's infotainment system cannot be achieved, thus failing to meet user needs and reducing the user experience.

[0085] Therefore, this application provides a vehicle personalization setting method, which can be applied to scenarios where the vehicle's infotainment system is personalized when a user gets into the vehicle.

[0086] For example, Figure 2 This is a schematic diagram illustrating a method for personalizing vehicle settings. (See attached image) Figure 2 , Figure 2 This includes vehicle 201 and user 202, where user 202 carries the key to vehicle 201.

[0087] User 202 arrives near vehicle 201 and wants to open the front left door of vehicle 201. When user 202 touches the door handle of the front left door of vehicle 201, multiple low-frequency antennas of vehicle 201 will sequentially emit radio frequency signals. Then, when the body controller of vehicle 201 receives the high-frequency signal emitted by the key and confirms that the key is indeed the key for vehicle 201, vehicle 201 can be unlocked, and user 202 can then open the front left door of vehicle 201 and enter vehicle 201.

[0088] When the left front door of vehicle 201 is detected to have changed from closed to open, the key ID of the first key (i.e., the key ID of the key closest to the left front door) is acquired at a first frequency. Then, if someone is detected in the target seat of vehicle 201, the key ID of the second key (i.e., the key ID of the key closest to the central control screen) is acquired at the first frequency. The key IDs of the first and second keys are then compared to determine if they are the same. If they are the same, it means the user who opened the left front door and is sitting in the seat is the same user. Based on this shared key ID, personalized settings can then be configured for the vehicle's infotainment system. For example, the multimedia central control screen can be controlled to log in to the user account corresponding to this key ID, and music frequently listened to by this user account can be played after login.

[0089] In this way, by acquiring the key identifiers of the first key and the second key under different behavioral scenarios, and determining whether the key identifiers acquired under different behavioral scenarios are the same, the system then performs personalized settings on the target vehicle's infotainment system based on the key identifiers if the key identifiers of the first key and the second key are the same under different behavioral scenarios, i.e., the keys belong to the same user under different behavioral scenarios. This ensures that the personalized settings of the infotainment system accurately meet the current user's needs, thereby improving the user experience.

[0090] The vehicle personalization setting method provided in the embodiments of this application will be explained in detail below.

[0091] Figure 3 This is a flowchart illustrating a vehicle personalization setting method provided in an embodiment of this application. This method can be applied to a vehicle controller, for example, to the vehicle's BCM (Body Control Module). See also... Figure 3 The method includes the following steps.

[0092] Step 301: When it is detected that any front door of the target vehicle changes from closed to open, the key identifier of the first key is acquired at a first frequency. The first key is the key near the front door.

[0093] Any front door of the target vehicle refers to the left or right front door of the target vehicle, that is, the door on the driver's side or the door on the passenger side of the target vehicle.

[0094] The first frequency is the frequency at which the low-frequency antenna of the target vehicle transmits low-frequency signals. The first frequency can be preset, for example, the first frequency can be set to 134 kHz (kilohertz).

[0095] The key identifier of the first key is used to uniquely identify the first key. For example, the key identifier can be a unique serial number of the key.

[0096] The key identifier can be a unique serial number, which is used to uniquely identify the corresponding key, thus ensuring that all the keys can be identified as one key.

[0097] In this embodiment, the key to the target vehicle can also be a digital key. Digital keys primarily utilize NFC (Near Field Communication) technology, allowing users to unlock, lock, and start the vehicle using NFC-enabled smartphones or wearable smart devices, such as smartwatches or wristbands. In this case, the first key can be the digital key that touches the front door. The key identifier of the first key can be the key identifier indicated in the digital certificate of the first key.

[0098] In this scenario, when the user opens the door, the key identifier of the first key is acquired at the highest frequency. That is, when the user opens one of the front doors of the target vehicle, the key identifier of the key closest to that front door is acquired at the highest frequency.

[0099] Specifically, upon detecting that any front door of the target vehicle changes from a closed state to an open state, the body controller can control multiple low-frequency antennas of the target vehicle to transmit low-frequency signals near the front door at a first frequency. Upon receiving the low-frequency signal, the first key near the front door replies with a high-frequency signal. Furthermore, the high-frequency signal replied by the first key carries the key identifier of the first key, allowing the body controller to obtain the key identifier.

[0100] Optionally, the multiple low-frequency antennas can be positioned on the target vehicle at various locations. Figure 1 The antenna location is shown.

[0101] Assuming that the left front door of the target vehicle is detected to change from closed to open, the order in which the multiple low-frequency antennas transmit low-frequency signals near the front door at the first frequency can be as follows: first, control the low-frequency antenna 4 of the front door to transmit low-frequency signals near the left front door at the first frequency; then, control the low-frequency antenna 5 of the right front door to transmit low-frequency signals near the right front door at the first frequency; then control the low-frequency antenna 2 to transmit low-frequency signals to the surrounding area at the first frequency; then control the low-frequency antenna 1 to transmit low-frequency signals to the surrounding area at the first frequency; and finally control the low-frequency antenna 3 to transmit low-frequency signals to the surrounding area at the first frequency.

[0102] Optionally, the operation in step 301 can be implemented by the following steps (1)-(2).

[0103] (1) If it is detected that any front door of the target vehicle changes from closed to open, and multiple vehicle keys are detected near the front door at a first frequency, the target positions of the multiple vehicle keys relative to the target vehicle are obtained respectively.

[0104] In this scenario, when any front door of the target vehicle changes from closed to open, the body control system detects multiple vehicle keys near that door. However, only one person is driving the vehicle. The system then needs to identify the key closest to the front door from among these keys—that is, determine which key belongs to the person who will be driving the vehicle. This information is crucial for determining how to personalize the vehicle's infotainment system.

[0105] Specifically, step (1) can be performed as follows: for any one of the multiple low-frequency antennas, control one low-frequency antenna to transmit a radio frequency signal at a first frequency; during the transmission of the radio frequency signal by the low-frequency antenna, if a reply signal is received from the multiple vehicle keys in response to the radio frequency signal, determine multiple initial distances based on the field strength value of the reply signal; and determine the target position of the multiple vehicle keys based on the initial distances between the multiple vehicle keys and the multiple low-frequency antennas, and the position of the multiple low-frequency antennas on the target vehicle.

[0106] The multiple initial distances are the distances between multiple vehicle keys and this low-frequency antenna. That is, for the initial distance corresponding to a single vehicle key, this initial distance is the distance between the vehicle key and the low-frequency antenna.

[0107] The response signal can be a high-frequency signal emitted by the vehicle key. After receiving the radio frequency signal transmitted by the low-frequency antenna, the vehicle key can transmit a high-frequency signal in response. Additionally, the response signal can carry the vehicle key's identification mark.

[0108] The field strength value of the returned signal indicates the signal strength of the returned signal within the signal transmission range of this low-frequency antenna. The closer the returned signal is to the low-frequency antenna, the greater its field strength value; conversely, the farther the returned signal is from the low-frequency antenna, the smaller its field strength value. Therefore, the field strength value of the returned signal can indicate the distance between the multiple vehicle keys and the low-frequency antenna.

[0109] By sequentially controlling each of the multiple low-frequency antennas to transmit radio frequency signals at a first frequency, during the transmission of radio frequency signals by each low-frequency antenna, a response signal from each of the multiple vehicle keys for each radio frequency signal is received, thereby subsequently obtaining the initial distance between the multiple vehicle keys and each of the multiple low-frequency antennas.

[0110] In this embodiment of the application, the plurality of low-frequency antennas are based on Figure 1When the target vehicle's left front door changes from closed to open, as shown in the diagram, low-frequency antennas 4, 5, 2, 1, and 3 can be sequentially controlled to transmit radio frequency signals at a first frequency. When the target vehicle's right front door changes from closed to open, it indicates that the right front door is open, and a key may be nearby. Therefore, low-frequency antenna 5 can be controlled to transmit radio frequency signals first, allowing subsequent control of low-frequency antennas 5, 4, 2, 1, and 3 to transmit radio frequency signals at the first frequency. This ensures the accuracy of vehicle key detection.

[0111] In this scenario, multiple vehicle keys are detected by sequentially controlling each of the multiple low-frequency antennas to transmit radio frequency signals, and the initial distance of each vehicle key relative to each low-frequency antenna is obtained. This allows for accurate determination of the target location of the multiple vehicle keys based on their initial distances relative to each low-frequency antenna and the position of the multiple low-frequency antennas on the target vehicle.

[0112] The operation of determining multiple initial distances based on the field strength value of the reply signal can be as follows: For any one of the multiple low-frequency antennas, the initial distance corresponding to the multiple vehicle keys is determined by the following formula (1) based on the field strength value of the reply signal of the multiple vehicle keys.

[0113]

[0114] Where, d i This is the distance between the i-th vehicle key and the j-th low-frequency antenna among the multiple vehicle keys, which is also the j-th initial distance corresponding to the i-th vehicle key. i Let A0 be the field strength value of the response signal from the i-th vehicle key received by the j-th low-frequency antenna, and let A0 be the absolute value of the field strength value when the i-th vehicle key is 1 meter away from the j-th low-frequency antenna. This value is usually a fixed value obtained through factory testing. n is the environmental attenuation factor.

[0115] In addition, the environmental attenuation factor n refers to the reduction in signal strength caused by various factors such as weather and environment during the transmission of low-frequency and high-frequency signals. Generally, the environmental attenuation factor n is a constant used to correct the field strength value, thereby enabling a more accurate target location to be obtained subsequently.

[0116] Thus, for the response signal of any vehicle key to the radio frequency signal among the multiple vehicle keys, the field strength value of the response signal of each vehicle key is processed by the above formula (1), so that the initial distance corresponding to each vehicle key can be obtained, that is, the multiple initial distances can be obtained.

[0117] Taking a target vehicle with three low-frequency antennas as an example, for any one of the multiple vehicle keys, the distance between the vehicle key and the first low-frequency antenna (the first initial distance) can be obtained by the above formula (1): the distance between the vehicle key and the first low-frequency antenna (the second initial distance) is d1, the distance between the vehicle key and the second low-frequency antenna (the second initial distance) is d2, and the distance between the vehicle key and the third low-frequency antenna (the third initial distance) is d3.

[0118] The operation of determining the target location of the multiple vehicle keys based on the initial distances between the multiple vehicle keys and the multiple low-frequency antennas, and the positions of the multiple low-frequency antennas on the target vehicle, can be as follows: For any one of the multiple vehicle keys, construct multiple circles with the positions of the multiple low-frequency antennas on the target vehicle as the center and the initial distances between the multiple low-frequency antennas and the vehicle key as the radius; the intersection of the multiple circles is determined as the target location of the vehicle key.

[0119] In this case, for any one of the multiple vehicle keys, the target location of the vehicle key is determined by considering the distance between the vehicle key and the multiple low-frequency antennas, thus obtaining a relatively accurate target location of the vehicle key.

[0120] The following example illustrates the process of determining the target location of multiple vehicle keys, using the example of a target vehicle equipped with three low-frequency antennas. For instance, Figure 4 This is a schematic diagram illustrating how to determine the target location of any one of the multiple vehicle keys. See [link / reference]. Figure 4 , Figure 4 The target vehicle has three low-frequency antennas deployed on it. The first low-frequency antenna is located at (x1, y1), the second at (x2, y2), and the third at (x3, y3). The initial distance between the vehicle key and the first low-frequency antenna is d1, the initial distance between the vehicle key and the second low-frequency antenna is d2, and the initial distance between the vehicle key and the third low-frequency antenna is d3. We can then construct three circles with center (x1, y1) and radius d1, center (x2, y2) and radius d2, and center (x3, y3) and radius d3, respectively.

[0121] Then, based on (x1, y1), (x2, y2), (x3, y3) and d1, d2, d3, the target location of the vehicle key can be determined by the following formulas (2)-(4).

[0122] (x1-x) 2 +(y1-y)=d12 (2)

[0123] (x2-x) 2 +(y2-y)=d2 2 (3)

[0124] (x3-x) 2 +(y3-y)=d3 2 (4)

[0125] Where (x, y) represents the target location of the vehicle key. It should be understood that multiple locations may be obtained by using formulas (2), (3), and (4) alone, but by using formulas (2)-(4), a single location can be accurately determined from multiple locations, namely the target location of the vehicle key. In this way, a unique and accurate target location of the vehicle key can be obtained.

[0126] It should be understood that when determining the target location of the multiple vehicle keys, assuming that the left front door of the target vehicle is open, the low-frequency antenna arranged on the left front door among the multiple low-frequency antennas can be located at (0, 0) on the target vehicle. Thus, the closer the target location of the multiple vehicle keys is to the location of the low-frequency antenna arranged on the left front door, the closer it is to the left front door of the target vehicle.

[0127] Thus, by performing the above steps on each of the multiple vehicle keys, the target location of each of the multiple vehicle keys can be obtained.

[0128] (2) Based on the target location of the multiple vehicle keys, determine the key identifier of the first key from the key identifiers of the multiple vehicle keys.

[0129] The first key is the key that is closest to the front door among the multiple vehicle keys.

[0130] Since the response signals from these multiple vehicle keys can carry key identifiers, their identifiers can be obtained upon detection, allowing the identification of the first key to be subsequently derived. Furthermore, the user of the key closest to the front door among these multiple vehicle keys is likely the user driving the target vehicle; therefore, the key closest to the front door can be identified as the first key.

[0131] In this case, the key with the smallest target location among the multiple vehicle keys—that is, the key with the smallest distance from the front door—is designated as the first key, and its key identifier is designated as the key identifier of the first key. This allows for a more accurate determination of the key identifier of the key carried by the user who will be driving the vehicle, which can then be used to accurately determine the key identifier corresponding to the personalized settings to be performed.

[0132] For example, if the target locations of the multiple vehicle keys are 1 meter, 2 meters, and 3 meters from the left front door, then the vehicle key 1 meter from the left front door can be designated as the first key, and the key identifier of the vehicle key 1 meter from the left front door can be designated as the key identifier of the first key.

[0133] It is worth noting that, prior to step 301, in response to the command to open the front door, the presence of a target key around the target vehicle can be detected at a second frequency; if a target key is present around the target vehicle, the front door can be unlocked.

[0134] The opening command for this front door can be triggered by the user. For example, the user can trigger the opening command for this front door by touching or pulling the door handle.

[0135] The target key is the vehicle key that matches the target vehicle. That is, it is the vehicle key that is bound to the target vehicle when it leaves the factory. In other words, only the target key can be used to unlock the target vehicle. No other key can unlock the target vehicle.

[0136] The second frequency is different from the first frequency. In the embodiments of this application, the second frequency may be less than the first frequency. For example, the first frequency may be 134 kHz, and the second frequency may be 125 kHz.

[0137] In this scenario, the target vehicle is locked and armed. By detecting the presence of a target key around the target vehicle at a second frequency, the target vehicle can be unlocked if the target key is present.

[0138] In addition, obtaining the key identifier of the first key at the first frequency means detecting the vehicle key at different frequencies under different behavioral scenarios, thereby reducing interference from other signals in the surrounding environment of the target vehicle, so as to ensure accurate detection of the vehicle key around the target vehicle and accurate acquisition of the key identifier.

[0139] Furthermore, after the front door of the target vehicle is unlocked, the target vehicle's multimedia host can be activated, thus preparing for subsequent login to the multimedia account corresponding to the key identifier, which is also preparing for subsequent personalized settings of the vehicle's infotainment system.

[0140] Step 302: If a person is detected in the target seat of the target vehicle, the key identifier of the second key is acquired at a first frequency. The second key is the key that is close to the central control screen of the target vehicle.

[0141] The target seat can be the driver's seat in the target vehicle, that is, the seat where the driver of the target vehicle sits. The central control screen refers to the screen of the multimedia host in the target vehicle.

[0142] Normally, when a user is driving a vehicle, after sitting in the driver's seat, they will place the key in the glove compartment between the driver's and passenger's seats. Therefore, the key near the center console screen is very likely the key carried by the user driving the target vehicle. Thus, if someone is detected in the target seat, the key near the center console screen can be retrieved.

[0143] In this scenario, if someone is detected in the target seat of the target vehicle, meaning the user in the target seat is very likely the user who will subsequently drive the target vehicle, then the key identifier near the central control screen can be detected, which is essentially detecting the key identifier of the key carried by the user driving the vehicle.

[0144] In this embodiment, when a person is detected in the target seat, the plurality of low-frequency antennas can be sequentially controlled to transmit radio frequency signals at a first frequency. When a vehicle key near the target vehicle receives the radio frequency signal, it can transmit a high-frequency signal to respond to the radio frequency signal. Subsequently, the target location of the vehicle key can be determined based on the field strength value of the responded signal and the positions of the plurality of low-frequency antennas within the target vehicle.

[0145] The specific process of determining the target location of the vehicle key has been described in detail in step 301 and will not be repeated here.

[0146] Since there may be multiple vehicle keys around the target vehicle, the target location of the multiple vehicle keys can be determined based on the field strength value of the response signal and the position of the multiple low-frequency antennas in the target vehicle, so that the second key can be selected from the multiple vehicle keys.

[0147] It should be understood that in step 302, the position of the low-frequency antenna arranged on the central control screen among the multiple low-frequency antennas in the target vehicle can be set to (0, 0). In this way, the closer the target position of a vehicle key is to the position of the low-frequency antenna on the central control screen, the closer the vehicle key is to the central control screen of the target vehicle. Then, this vehicle key is the second key, and the key identifier of this vehicle key is the key identifier of the second key.

[0148] It is worth noting that before step 302, it can be determined whether there is anyone in the target seat.

[0149] Specifically, determining whether there is someone in the target seat can be achieved in the following two possible ways.

[0150] The first possible implementation is to determine that there is someone in the target seat if the pressure value of the target seat is greater than or equal to a preset pressure threshold, and to determine that there is no one in the target seat if the pressure value of the target seat is less than the preset pressure threshold.

[0151] Optionally, the target seat includes a pressure sensor. The pressure value of the target seat can be detected by the pressure sensor.

[0152] The preset pressure threshold can be set in advance, and the preset pressure threshold can be set to a relatively large value.

[0153] In this situation, if the pressure value of the target seat is greater than or equal to the preset pressure threshold, it indicates that the target seat is under significant pressure, and therefore it can be determined that someone is in the target seat. If the pressure value of the target seat is less than the preset pressure threshold, it indicates that the target seat is under less pressure, and therefore it can be determined that no one is in the target seat.

[0154] Optionally, if the pressure value of the target seat is greater than or equal to a preset pressure threshold, and the temperature value of the target seat is greater than or equal to a preset temperature threshold, then it can be determined that there is someone in the target seat; if the temperature value of the target seat is less than the preset temperature threshold, then it can be determined that there is no one in the target seat.

[0155] The temperature of the target seat can be detected by the temperature sensor on the target seat.

[0156] The preset temperature threshold can be set in advance, and the preset temperature threshold can be set according to the temperature value of a person sitting on the seat.

[0157] Consider a scenario where a very heavy object is placed on the target seat, exerting pressure similar to that of a human body. In this case, the pressure on the target seat is also high, but there is no person on the seat; instead, a heavy object is placed there. This could lead to the object being mistakenly identified as a person. Therefore, it's necessary to further determine whether the temperature of the target seat meets the requirements.

[0158] In this situation, if the temperature of the target seat is greater than or equal to the preset temperature threshold, it means that the temperature of the target seat has reached the temperature when a person is sitting in the seat, and therefore it can be determined that there is someone in the target seat. If the temperature of the target seat is less than the preset temperature threshold, it means that the temperature of the target seat has not yet reached the temperature when a person is sitting in the seat, and therefore it can be determined that there is no one in the target seat.

[0159] This avoids misidentifying heavy objects on the target seat as people, thus allowing for a more accurate determination of whether there is someone on the target seat.

[0160] The second possible approach is to obtain image information of the target seat in the vehicle; perform facial recognition on the image information; if the recognition result indicates that there is someone in the target seat, then determine that there is someone in the target seat; if no one is recognized, then determine that there is no one in the target seat.

[0161] Optionally, image information of the target seat can be obtained by capturing images or videos of the target seat using a camera inside the vehicle.

[0162] After the camera captures an image or video of the target seat, facial recognition can be performed on the captured image or video to identify whether a person is present in the image or video. If the recognition result indicates that a person is present in the image or video, it is determined that someone is in the target seat.

[0163] In this situation, obtaining images or videos of the target seat through a camera can more accurately determine whether there is someone in the target seat.

[0164] Optionally, the operation of performing face recognition on image information can be as follows: inputting image information into a face recognition model, recognizing the image information through the face recognition model, and outputting the recognition result.

[0165] A face recognition model is used to identify whether a human figure exists in an image. If the output indicates that a human figure is present, then the presence of a human figure in the image is confirmed.

[0166] It is worth noting that before a face recognition model can be used to identify image information and output the recognition result, the face recognition model needs to be trained.

[0167] Specifically, the computer device can acquire multiple training samples and use these multiple training samples to train the neural network model to obtain the face recognition model.

[0168] The computer device can be a server, which is specifically designed to train the face recognition model.

[0169] These multiple training samples can be pre-set. Each training sample includes sample data and sample labels. The sample data is an image of a seat inside a vehicle, and the sample label is the recognition result corresponding to the sample data. That is, the input data for each training sample is an image, and the sample label is the recognition result corresponding to the sample data.

[0170] This neural network model can include multiple network layers, including an input layer, multiple hidden layers, and an output layer. The input layer is responsible for receiving input data; the output layer is responsible for outputting the processed data; the multiple hidden layers are located between the input and output layers and are responsible for processing the data. These hidden layers are not visible to the outside world. For example, this neural network model can be a convolutional neural network model, etc.

[0171] In this process, when a computer device trains a neural network model using multiple training samples, for each training sample, the input data from that training sample is input into the neural network model to obtain output data. A loss function is then used to determine the loss value between the output data and the sample labels in that training sample. The parameters in the neural network model are then adjusted based on this loss value. After adjusting the parameters of the neural network model based on each of the multiple training samples, the neural network model with adjusted parameters becomes the face recognition model.

[0172] The operation of adjusting the parameters in the neural network model based on the loss value by the computer device can refer to relevant technologies, and will not be described in detail in the embodiments of this application.

[0173] For example, computer equipment can use formulas This allows for the adjustment of any parameter in the neural network model. These are the adjusted parameters. W is the parameter before adjustment. α is the learning rate, which can be preset, such as 0.001, 0.000001, etc., but this application does not limit this to a single value. dw is the derivative of the loss function with respect to W, which can be obtained from the loss value.

[0174] Thus, through steps 310 and 302 above, the key identifier of the first key when the front door of the target vehicle is opened, and the key identifier of the second key when someone is in the target seat can be obtained. In other words, the key identifiers of the keys under different behavioral scenarios can be obtained, so that the personalized settings of the vehicle's infotainment system can be determined accordingly.

[0175] Step 303: If the key identifier of the first key and the key identifier of the second key are the same, personalize the vehicle's infotainment system based on the key identifier of the first key.

[0176] If the key identifiers of the first key and the second key are the same, it means that the key identifier of the key near the front door when it is open is the same as the key identifier of the key near the central control screen when someone is in the target seat. In other words, the user who opened the front door and the user in the target seat are likely the same user, and therefore, the user who subsequently drives the vehicle is also very likely to be the same user. This allows for personalized settings of the vehicle's infotainment system based on this shared key identifier.

[0177] In addition, under normal circumstances, when a user drives a target vehicle, the target vehicle can identify the key identifier of the key carried by the user currently driving the vehicle. As a result, the settings made to the vehicle's infotainment system by the user during the driving process can be bound to this key identifier. Based on this, the user can obtain the preference data of the infotainment system corresponding to this key identifier, that is, the specific settings that the user of the key identified by this key identifier frequently makes to the infotainment system.

[0178] Therefore, in this scenario, by using the same key for different user behaviors, the vehicle's infotainment system can be personalized based on the key's identifier. This accurately achieves personalized settings for the infotainment system, ensuring that the personalized settings meet the current user's needs and thus improving the user experience.

[0179] Specifically, step 303 can be performed as follows: if the key identifier of the first key and the key identifier of the second key are the same, obtain the preference information corresponding to the key identifier of the first key; and based on the preference information, make personalized settings for the vehicle's infotainment system.

[0180] The preference information corresponding to the key identifier of the First Key includes the parameter settings made by the user of the First Key to various in-vehicle devices when driving the target vehicle. For example, the preference information corresponding to the key identifier of the First Key includes the parameters for adjusting the driver's seat in the target vehicle. Another example is the user's account used to log into the multimedia system, frequently used music lists, and frequently listened radio stations when driving the target vehicle.

[0181] Vehicle infotainment systems refer to the devices corresponding to the various functions of the vehicle's infotainment system. For example, vehicle infotainment systems include the vehicle's multimedia head unit, air conditioning, etc.

[0182] In this scenario, by obtaining the preference information corresponding to the key identifier of the first key, the vehicle's infotainment system can be personalized based on this preference information. This ensures that the parameter settings of each subsequent infotainment system are the parameter settings preferred by the user currently driving the target vehicle, thus providing convenience for the user and improving the user experience.

[0183] The personalized settings for the vehicle's infotainment system based on this preference can include at least one of the following.

[0184] First, if the preference information includes a list of frequently used audios, control the central control screen to play audios from the frequently used audio list.

[0185] The frequently used audio list refers to the list of audios that the current user has played the most times while driving the target vehicle in the past. In other words, the audios in the frequently used audio list are the audios that the current user plays most often.

[0186] In this case, to improve the user experience, audio from this frequently used audio list can be played after the current user gets into the car and starts driving.

[0187] In addition, in this embodiment of the application, the preference information may include the multimedia host account corresponding to the key identifier of the first key. In this case, the multimedia host can be controlled to log in to the multimedia host account included in the preference information.

[0188] After logging into the multimedia host account, information such as a list of frequently used audio files and frequently used navigation addresses can be displayed, allowing you to control the central control screen of the multimedia host to play audio files from the list of frequently used audio files.

[0189] Second, if the preference information includes air conditioning preference parameters, control the air conditioning of the target vehicle to operate according to the air conditioning preference parameters.

[0190] The air conditioning preference parameters can include parameters such as air conditioning temperature, airflow direction, and airflow force that the current user frequently sets while driving the target vehicle in the past.

[0191] For example, if a user frequently sets the air conditioning temperature to 26°C, the airflow direction to "direct towards the seat," and the fan speed to level 2 while driving the target vehicle, then when the user gets in the car, they can also set the air conditioning temperature to 26°C, the airflow direction to "direct towards the seat," and the fan speed to level 2.

[0192] Third, if the preference information includes the target seat adjustment parameters, control the target vehicle to adjust the target seat according to the target seat adjustment parameters.

[0193] Target seat adjustment parameters refer to the parameters that the current user frequently adjusts to the target seat during their past driving of the target vehicle. These parameters may include seat movement distance and target seat back angle.

[0194] When the target seat is the driver's seat, the driver's seat of the target vehicle is adjusted to the seat distance and angle that the driver frequently adjusts.

[0195] For example, the target seat adjustment parameters are: the target seat moves forward 2 cm and the target seat back angle is 30°. Then, when the current user gets into the vehicle, adjusting the target seat parameters can be done by controlling the target seat to move forward 2 cm and setting the target seat back angle to 30°.

[0196] In this way, once the user gets into the vehicle, the above-mentioned personalized settings are made to the vehicle's infotainment system, so that the user does not need to make the above settings again after getting into the vehicle, thereby providing convenience for the user and improving the user experience.

[0197] Of course, in addition to personalizing the vehicle's infotainment system using at least one of the three methods mentioned above, other personalized settings can also be made. For example, navigation to frequently visited locations or rearview mirror angle adjustment. This application embodiment does not limit these settings.

[0198] Optionally, if the key identifier of the first key and the key identifier of the second key are different, if the target vehicle is detected to be powered on, the key identifier of the third key is obtained at a first frequency. The third key is the key that is close to the central control screen of the target vehicle. Based on the key identifier of the third key, the vehicle's infotainment system is personalized.

[0199] If the key identifiers of the first key and the second key are different, it means that the key identifier of the key near the front door when it is open is different from the key identifier of the key near the center console screen when someone is in the target seat. In other words, the user opening the front door and the user in the target seat are likely not the same user. Therefore, the user sitting in the target seat may not be the user who will drive the target vehicle later. Consequently, it is unclear which key identifier should be used to personalize the vehicle's infotainment system.

[0200] In this scenario, when the target vehicle is powered on, it indicates that the vehicle has started, confirming that the user currently sitting in the target seat is the same user who started the vehicle, meaning the user driving the target vehicle is the same user currently in the target seat. At this point, the vehicle's infotainment system can be personalized based on the key identifier of the key closest to the central control screen; that is, personalized settings can be applied to the vehicle's infotainment system based on the key identifier of the third key.

[0201] This ensures that the in-vehicle infotainment system is always personalized based on the key identifier of the key carried by the user currently driving the target vehicle. This guarantees that the personalized settings applied to the in-vehicle infotainment system in this situation align with the preferences of the current user, thus meeting their needs and enhancing the user experience.

[0202] It is worth noting that, in this embodiment, if the vehicle-mounted device can be controlled by the multimedia host, after obtaining the key identifier of the first key, the key identifier of the first key can be sent to the multimedia host first; then the multimedia host can obtain the preference information corresponding to the key identifier of the first key. After the body controller obtains the key identifier of the second key, it sends the key identifier of the second key to the multimedia host; then the multimedia host determines whether the key identifier of the first key and the key identifier of the second key are the same. If the key identifier of the first key and the key identifier of the second key are the same, the multimedia account corresponding to the key identifier of the first key is logged in, and then the multimedia host performs corresponding personalized settings for the vehicle-mounted device based on the corresponding preference information.

[0203] In this way, by sending the key identifier of the first key to the multimedia host in advance, the multimedia host can obtain the corresponding preference information in advance. As a result, if the key identifier of the first key and the key identifier of the second key are the same, the multimedia host can accurately and quickly log in to the corresponding multimedia account, and then accurately and quickly make corresponding personalized settings for the vehicle's equipment.

[0204] Through steps 301-303 above, personalized settings for the vehicle's infotainment system can be achieved, thereby meeting the needs of the user currently driving the target vehicle. Optionally, steps 301-303 above can be applied to the following two scenarios.

[0205] In the first scenario, the user opens the left front door of the target vehicle, enters the driver's seat, and drives the target vehicle.

[0206] In this scenario, if the front left door of the target vehicle can be opened normally, the user can open the front left door and enter the driver's seat to drive the target vehicle.

[0207] In this scenario, when the left front door of the target vehicle is detected to be open, the vehicle's infotainment system can be personalized by executing steps 301-303 described above. Specifically, when the left front door of the target vehicle is detected to have changed from closed to open, the key identifier of the first key is acquired at a first frequency; at this time, the first key is the key closest to the left front door. Then, when someone is detected in the driver's seat of the target vehicle, the key identifier of the second key is acquired at the first frequency. Finally, if the key identifiers of the first and second keys are identical, the vehicle's infotainment system is personalized based on the key identifier of the first key.

[0208] In this way, even if the user opening the driver's side door is the same as the user sitting in the driver's seat, the vehicle's infotainment system can be personalized to meet the needs of the user currently driving the target vehicle, thereby enhancing the driver's driving experience.

[0209] In the second scenario, if the left front door cannot be opened, the user opens the right front door of the target vehicle, enters the driver's seat from the passenger side, and drives the target vehicle.

[0210] In this scenario, if the left front door of the target vehicle is obstructed from opening due to obstacles or other vehicles, the user can open the right front door, enter the passenger seat, and then move to the driver's seat to drive the vehicle. In other words, in this scenario, the user who opens the right front door is the one who subsequently drives the target vehicle.

[0211] In this scenario, when the right front door of the target vehicle is detected to be open, the vehicle's infotainment system can be personalized by executing steps 301-303 described above. Specifically, when the right front door of the target vehicle is detected to have changed from closed to open, the key identifier of the first key is acquired at a first frequency; at this time, the first key is the key closest to the right front door. Then, when someone is detected in the driver's seat of the target vehicle, the key identifier of the second key is acquired at the first frequency. Finally, if the key identifiers of the first and second keys are identical, the vehicle's infotainment system is personalized based on the key identifier of the first key.

[0212] This allows for personalized settings of the vehicle's infotainment system when the user opening the passenger-side door is the same person sitting in the driver's seat. In other words, if the user opening the right front door is the same person who will subsequently drive the vehicle, the infotainment system is personalized based on the key identifier of the primary key, thus meeting the needs of the current driver and enhancing their driving experience.

[0213] In addition, in daily life, there may be scenarios where all the doors of the target vehicle are blocked and cannot be opened normally. In this case, the user can enter from the trunk, move to the driver's seat, and drive the target vehicle. In this case, the following steps (1)-(3) can be performed to personalize the vehicle's infotainment system settings.

[0214] (1) In response to a command to open the trunk of the target vehicle, the key identifier of the fourth key is acquired at a first frequency.

[0215] The fourth key is the key near the trunk, and it is the key near the trunk that is used when the trunk of the target vehicle is opened.

[0216] The trunk opening command for the target vehicle can be triggered by the user. For example, the user can trigger the trunk opening command by pressing the opening button on the trunk. Alternatively, the user can trigger the trunk opening command by pressing the trunk opening button on the target vehicle's key.

[0217] In this case, upon receiving a command to open the trunk of the target vehicle, the system checks whether the target vehicle's key is near the trunk and retrieves the key identifier of the key near the trunk.

[0218] In this embodiment, upon receiving a trunk opening command, the plurality of low-frequency antennas can be sequentially controlled to transmit radio frequency signals at a first frequency. When a vehicle key near the target vehicle receives the radio frequency signal, it can transmit a high-frequency signal to respond to the radio frequency signal. Subsequently, the target location of the vehicle key can be determined based on the field strength value of the responded signal and the positions of the plurality of low-frequency antennas within the target vehicle.

[0219] The specific process of determining the target location of the vehicle key has been described in detail in step 301 and will not be repeated here.

[0220] Additionally, since it detects the key near the trunk, the multiple low-frequency antennas are positioned as follows: Figure 1 In the arrangement shown, low-frequency antennas 6, 2, 1, and 3 can be controlled to transmit radio frequency signals outward in sequence.

[0221] It should be understood that the low-frequency antenna located in the trunk among the multiple low-frequency antennas can be set to (0, 0) in the target vehicle. In this way, the closer the target position of a vehicle key is to the position of the low-frequency antenna in the trunk, the closer the vehicle key is to the trunk of the target vehicle. Therefore, this vehicle key is the fourth key, and its key identifier is the key identifier of the fourth key.

[0222] (2) When the trunk is detected to change from closed to open, the key identifier of the fifth key is acquired at a second frequency.

[0223] The fifth key is the key near the trunk, and it is the key near the trunk that is detected when the trunk changes from a closed state to an open state.

[0224] In this scenario, when the trunk of the target vehicle is opened, the key near the trunk is detected again, along with the key's identifier. This information is then used to personalize the vehicle's infotainment system.

[0225] In addition, by detecting the vehicle key at different frequencies under different conditions in the trunk, interference from other signals in the surrounding environment of the target vehicle can be reduced, so as to ensure accurate detection of the vehicle key near the trunk of the target vehicle and accurate acquisition of the key identifier.

[0226] (3) If the key identifier of the fourth key is the same as that of the fifth key, the vehicle's infotainment system is personalized based on the key identifier of the fourth key.

[0227] If the key identifiers of the fourth and fifth keys are the same, it means that the user who triggered the trunk opening command and the user who opened the trunk are the same user. In other words, this user will subsequently enter the target vehicle through the trunk and then move to the driver's seat to drive the vehicle.

[0228] In this case, by using the key identifier based on the fourth key, the vehicle's infotainment system can be personalized, which can meet the needs of the user driving the vehicle and thus provide convenience for the user.

[0229] This provides a way to personalize in-vehicle infotainment systems for various scenarios in daily life. By following the appropriate steps in different situations, users can accurately customize the system settings. This ensures accurate settings regardless of the scenario, thereby enhancing the user experience.

[0230] In this embodiment, when it is detected that any front door of the target vehicle changes from a closed state to an open state, the key identifier of the first key is acquired at a first frequency. Then, when it is detected that someone is in the target seat of the target vehicle, the key identifier of the second key is acquired at the first frequency. Finally, if the key identifiers of the first key and the second key are the same, the vehicle's infotainment system is personalized based on the key identifier of the first key. Thus, by acquiring the key identifiers of the first key and the second key under different behavioral scenarios and determining whether the key identifiers acquired under different behavioral scenarios are the same, and then, if the key identifiers of the first key and the second key are the same under different behavioral scenarios (i.e., the keys under different behavioral scenarios belong to the same user), the vehicle's infotainment system is personalized based on the key identifiers. This accurately achieves personalized settings for the infotainment system, ensuring that the personalized settings are tailored to the current user's needs, thereby improving the user experience.

[0231] Figure 5 This is a schematic diagram of a vehicle personalization setting device provided in an embodiment of this application. This vehicle personalization setting device can be implemented as part or all of a vehicle by software, hardware, or a combination of both. The vehicle can be described below. Figure 6 The vehicle shown. See also Figure 5 The device includes: a first acquisition module 501, a second acquisition module 502, and a first setting module 503.

[0232] The first acquisition module 501 is used to acquire the key identifier of the first key at a first frequency when it is detected that any front door of the target vehicle changes from a closed state to an open state. The first key is the key that is close to the front door.

[0233] The second acquisition module 502 is used to acquire the key identifier of the second key at a first frequency when a person is detected in the target seat of the target vehicle. The second key is the key that is close to the central control screen of the target vehicle.
