[0045] In order to enable those of ordinary skill in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0046] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of this application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] For the sake of easy understanding, the seat adjustment method provided by the present application will be specifically introduced below in conjunction with the accompanying drawings.

[0048] As Figure 1 shown, Figure 1 A vehicle 100 is provided. The seat adjustment method provided by the embodiments of the present application can be applied in the vehicle 100. A vehicle can also be referred to as a transportation vehicle (vehicle), a mobile carrier (mobile carrier), an electric vehicle (electric vehicle, EV), a hybrid electric vehicle (hybrid electric vehicle, HEV), a plug-in hybrid electric vehicle (plug-in hybrid electric vehicle, PHEV), a fuel cell vehicle (fuel cell vehicle, FCV), an autonomous vehicle (autonomous vehicle), an intelligent and connected vehicle (intelligent and connected vehicle, ICV), a driverless vehicle (driverless vehicle), etc.

[0049] In the embodiments of the present application, the vehicle 100 can be a sedan, a sport utility vehicle (sport utility vehicle, SUV), a truck, an electric vehicle, a motorcycle, a tricycle, a special vehicle (such as an ambulance, a fire truck, a police car, etc.), a driverless taxi, an intelligent and connected bus, an autonomous logistics vehicle, an electric truck, etc. In addition, the method is also applicable to various special vehicles, such as agricultural vehicles, mining vehicles, forestry vehicles, airport vehicles, port vehicles, etc. The present application does not make specific limitations in this regard.

[0050] As Figure 2 shown, Figure 2 It is a seat adjustment system.

[0051] In a possible implementation manner, the seat adjustment system 200 may include a seat adjustment device 201, a data acquisition device 202, and a seat 203.

[0052] Optionally, Figure 2 a communication connection may be established between the seat adjustment device 201 and the data acquisition device 202 in [[...]]. A connection may be established between the data acquisition device 202 and the seat 203. A connection may be established between the seat adjustment device 201 and the seat 203.

[0053] In practical applications, the seat adjustment device 201 may be communicatively connected to one or more data acquisition devices 202. The seat adjustment device 201 may be connected to one or more seats 203 on the vehicle.

[0054] For ease of understanding, this application is described by taking the communication connection between one seat adjustment device 201 and one data acquisition device 202 as an example.

[0055] Optionally, Figure 2 the seat adjustment device 201 and the data acquisition device 202 in [[...]] may be functional modules integrated into the same device, or may be devices independently provided. This application does not limit this.

[0056] It is easy to understand that when the seat adjustment device 201 and the data acquisition device 202 are functional modules integrated into the same device, the communication method between the seat adjustment device 201 and the data acquisition device 202 is the communication between internal modules of the device. In this case, the communication process between the two is the same as the "communication process when the seat adjustment device 201 and the data acquisition device 202 are independently provided".

[0057] For ease of understanding, this application is mainly described by taking the case where the seat adjustment device 201 and the data acquisition device 202 are independently provided as an example.

[0058] Figure 2 The data acquisition device 202 in [[...]] may collect the movement trajectory and action information of the target user. The seat adjustment device 201 may receive the movement trajectory and action information sent by the data acquisition device 202, and based on the movement trajectory and action information, determine the door to be opened by the target user. Furthermore, based on the door to be opened, determine the first seat on which the target user is to be seated, and further, in the case where the target user is a co-rider, adjust the posture of the first seat based on the seat usage preference set of the target user.

[0059] Optionally, Figure 2 the seat adjustment device 201 in [[...]] may be a terminal, or a server, or other types of electronic devices. Figure 2 What is shown in [[...]] is only an example of the device form of the seat adjustment device 201, and does not limit it.

[0060] When the seat adjustment device 201 is a terminal, the terminal can be a device that provides voice and / or data connectivity to a target user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. The terminal can communicate with one or more core networks via a radio access network (RAN). The terminal can be a mobile terminal, such as a computer with a mobile terminal, or a mobile device built into the vehicle 100, which exchanges language and / or data with the wireless access network. For example, mobile phones, tablets, laptops, netbooks, personal digital assistants (PDAs). This application does not make any restrictions on this.

[0061] When the seat adjustment device 201 is a server, the server can be a single server, or alternatively, it can be a server cluster composed of multiple servers. In some embodiments, the server cluster can also be a distributed cluster. This application does not make any restrictions on this.

[0062] It should be noted that the structure illustrated in the embodiments of this application does not constitute a limitation on the seat adjustment system 200. It can include more or fewer components than shown, or combine certain components, or split certain components, or have different component arrangements. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0063] Figure 3 is a flowchart of a seat adjustment method shown according to an exemplary embodiment, as Figure 3 shown, the seat adjustment method includes the following steps: S301 - S304.

[0064] S301. Determine the movement trajectory and action information of the target user through the video information captured by the external vehicle camera.

[0065] In a possible implementation manner, when the target user gradually approaches the vehicle, the external vehicle camera can monitor the movement trajectory and action information of the target user in real time, and send the movement trajectory and action information to the seat adjustment device. For example, when the target user starts walking towards the vehicle from a distance, the external vehicle camera can accurately identify its position, and continuously update the position information and action information as the target user moves. The seat adjustment device can receive the movement trajectory and action information of the target user sent by the external vehicle camera.

[0066] Optionally, the action information can include the target user reaching out to open the door, taking the key, etc. This application does not make specific restrictions on this.

[0067] S302. Determine the door to be opened by the target user based on the movement trajectory and action information of the target user.

[0068] In one possible implementation, the seat adjustment device may predict the door that the target user may open based on the movement trajectory and action information of the target user, as the door to be opened.

[0069] For example, if the target user's movement trajectory is toward the passenger door of the vehicle, the seat adjustment device can use the passenger door as the door to be opened based on this trajectory information. Alternatively, when the target user walks in a straight line from the right front of the vehicle toward the passenger door, and when approaching the door, he or she obviously opens the door to enter, the seat adjustment device can use the passenger door as the door to be opened.

[0070] Secondly, if the target user is carrying heavy objects in both hands and the body weight is leaning to one side, the seat adjustment device can predict that the rear seat, which is more convenient for placing objects and easier for getting on and off the vehicle, is the seat that the target user may sit on, and the seat adjustment device can determine the rear door as the door to be opened. For example, when the target user is carrying a large shopping bag in both hands and the body is slightly tilted to the right, and there is a large space next to the right rear seat of the vehicle for placing objects, the seat adjustment device can tend to predict that the target user will sit on the right rear seat, and the seat adjustment device can determine the rear door as the door to be opened.

[0071] S303: Determine a first seat where the target user is to sit based on the vehicle door to be opened.

[0072] In a possible implementation, the seat adjustment device may select a seat located in a cockpit area where a door to be opened is located as a candidate seat.

[0073] Exemplarily, when the vehicle is a left-hand drive vehicle, the cabin area corresponding to the left front door is the driver's seat area, and the cabin area corresponding to the right rear door is the rear seat area of ​​the vehicle.

[0074] In a possible implementation, the seat adjustment device may store the target user's historical sitting times on different seats. The seat adjustment device may determine the first seat from the candidate seats based on the target user's historical sitting times on the candidate seats.

[0075] For example, if the target user has multiple records of sitting in a candidate seat before, the seat adjustment device may determine the candidate seat as the first seat.

[0076] In yet another possible implementation, when it is determined that there are other target users behind the target user approaching the door to be opened, a candidate seat farthest from the door to be opened is selected as the first seat.

[0077] That is to say, in the case that there are other target users who need to get on the vehicle through the door to be opened after determining the target user, the seat adjustment device can use the candidate seat farther away from the door to be opened as the first seat.

[0078] S304. When the target user is a multiple-rider, adjust the posture of the first seat based on the seat usage preference set of the target user.

[0079] Among them, the seat usage preference set includes the seat usage preferences of the target user for at least one seat in the vehicle. A multiple-rider can be used to represent a person who has ridden in the current vehicle at least once.

[0080] Exemplarily, the seat usage preference set can include the target user's preferences for aspects such as the tilt angle of the seat back, seat height, headrest position, and lumbar support strength for at least one seat in the vehicle.

[0081] In a possible implementation manner, the seat adjustment device can be deployed with a storage module. Multiple target users' seat usage preference sets can be deployed in the storage module. The seat adjustment device can obtain the identity information of the target user. The seat adjustment device can retrieve the seat usage preference set that matches the identity information of the target user in the storage module.

[0082] Optionally, the method for obtaining the identity information of the target user can be set according to actual requirements.

[0083] Exemplarily, the seat adjustment device can use a camera to capture the facial image of the target user, and determine the identity information of the target user based on the matching of the facial image with the stored facial feature template.

[0084] Alternatively, when the target user touches the vehicle door handle or the fingerprint recognition area on the seat with a finger, the seat adjustment device can collect the fingerprint image of the target user through the fingerprint recognition sensor, and then compare it with the fingerprint template pre-stored in the storage module to confirm the identity of the target user.

[0085] In another possible implementation manner, if there is no first seat usage preference information in the seat usage preference set, the seat adjustment device can correct the second seat usage preference information in the seat usage preference set, and adjust the posture of the first seat based on the corrected second seat usage preference information.

[0086] Among them, the first seat usage preference information may be the seat usage preference information of the target user for the first type of seat. The first type of seat can be used to characterize the type of the first seat. The second seat usage preference information may be the seat usage preference information of the target user for the second type of seat. The second type of seat is different from the first type of seat. The type of seat may include at least one of a driver's seat, a front passenger seat, and a rear seat.

[0087] In a possible implementation manner, in order to correct the second seat usage preference information in the seat usage preference set, the seat adjustment device may determine a parameter correction coefficient between the first type of seat and the second type of seat. The seat adjustment device may determine the corrected second seat usage preference information based on the parameter correction coefficient and the second seat usage preference information. For the specific implementation manner of the seat adjustment device to correct the second seat usage preference information in the seat usage preference set, reference may be made to S401 - S402 below. Details are not described herein again.

[0088] In another possible implementation manner, if there is first seat usage preference information in the seat usage preference set, the seat adjustment device may adjust the posture of the first seat based on the first seat usage preference.

[0089] In a possible implementation manner, the target user may also be the first passenger. The first passenger may be a person who takes the current vehicle for the first time.

[0090] In a possible implementation manner, when the target user is the first passenger, the seat adjustment device may determine a target seat posture matching the target user based on the body feature information and the first type of seat. The seat adjustment device may adjust the posture of the first seat based on the target seat posture.

[0091] Among them, the body feature information may include height, weight, body type (such as fat or thin), dimensions of various body parts (such as leg length, arm length, etc.). The target seat posture may include the tilt angle of the seat back, the seat height, the position of the headrest, etc.

[0092] In a possible implementation manner, the seat adjustment device may obtain the body feature information in multiple ways. For example, the seat adjustment device may detect the pressure of the target user on the seat through pressure sensors (which may be distributed on the seat surface). Or, the seat adjustment device may obtain the image information of the first passenger through an in - vehicle camera or an out - vehicle camera, and further determine the body feature information of the target user based on the image information.

[0093] In a possible implementation, to determine the target seat posture matching the first-time rider, the seat adjustment device may determine whether there is a target seat usage preference set in the seat usage preference library whose matching degree with the body feature information is greater than a preset threshold. If there is a target seat usage preference set, the seat adjustment device may determine the target seat posture based on the first seat type and the target seat usage preference set. The specific implementation of the seat adjustment device to determine the target seat posture matching the target user when the target user is the first-time rider may refer to the following S501 - S502. Details are not elaborated here.

[0094] Based on the above technical solution, the present application can accurately predict the first seat where the target user may sit by comprehensively considering various factors such as the movement trajectory and action information of the target user. After determining the first seat, the seat adjustment device can adjust the posture of the first seat in advance according to the pre-acquired body feature information and / or seat usage preference set of the target user to ensure that the target user can immediately enjoy a comfortable and personalized seat environment after entering the vehicle.

[0095] In some embodiments, to correct the second seat usage preference information in the seat usage preference set, the seat adjustment method provided by the present application further includes the following steps: S401 - S402.

[0096] S401. Determine the parameter correction coefficient between the first seat type and the second seat type.

[0097] In a possible implementation, the seat adjustment device may preset the association information between various seat types and the corresponding parameter correction rules. After receiving the information of the first seat type and the second seat type, the seat adjustment device can quickly retrieve relevant information in the database and analyze the differences between the two seat types in terms of structure, function, ergonomic design, etc. For example, if the first seat is the driver's seat and the second seat is the co-driver's seat, the seat adjustment device may consider that the driver's seat requires more frequent operations and better forward visibility, while the co-driver's seat pays more attention to comfort, and thus calculate the corresponding parameter correction coefficient based on these differences.

[0098] Optionally, this coefficient may be a decimal between 0 and 1 or a value greater than 1, specifically depending on the characteristics and difference degree of the two seat types. The present application does not make specific limitations on this.

[0099] S402. Determine the corrected second seat usage preference information based on the parameter correction coefficient and the second seat usage preference information.

[0100] In a possible implementation manner, after determining the parameter correction coefficient, the seat adjustment device can adjust each parameter in the second seat usage preference according to the parameter correction coefficient to determine the corrected second seat usage preference information. For example, if the parameter correction coefficient indicates that the first seat needs to be at a higher height than the second seat, the device will multiply the height parameter in the second seat usage preference by a correction coefficient greater than 1 to obtain the height parameter suitable for the first seat. For other parameters such as angle and inclination, the seat adjustment device can also be corrected in a similar manner. After this series of calculations and adjustments, the seat adjustment device can determine the corrected second seat usage preference information.

[0101] In yet another possible implementation manner, if there is a first seat usage preference, the seat adjustment device can adjust the posture of the first seat based on the first seat usage preference.

[0102] Based on this, the present application can accurately convert the preference information of the user for the second seat type to the first seat type through the parameter correction coefficient between different types of seats, making the posture adjustment of the first seat more in line with the user's preference for the seat.

[0103] In some embodiments, in order to determine the target seat posture matching the target user, the seat adjustment method provided by the present application further includes the following steps: S501 - S502.

[0104] S501. Determine whether there is a target seat usage preference set in the seat usage preference library whose matching degree with the body feature information is greater than a preset threshold.

[0105] Among them, the seat usage preference library may include seat usage preference sets corresponding to multiple users respectively. The matching degree can be used to characterize the similarity between the body feature information and the first body feature information. The first body feature information can be used to characterize the body feature information of the user.

[0106] Optionally, the preset threshold can be set according to actual needs. For example, the preset threshold can be 90% or 95%. The present application does not make specific limitations on this.

[0107] In a possible implementation manner, after receiving the body feature information of the target user, the seat adjustment device can retrieve from the seat usage preference library whether there is a first body feature information that matches the body feature information.

[0108] It should be noted that the similarity is not a simple numerical comparison, but a comprehensive evaluation considering multiple factors. For example, for the feature of height, the seat adjustment device not only needs to consider the proximity of the absolute value, but also needs to comprehensively judge in combination with other features such as weight.

[0109] S502. If there is a target seat usage preference set, determine the target seat posture based on the first seat type and the target seat usage preference set.

[0110] In a possible implementation, the seat adjustment device can determine a target parameter correction coefficient between the first seat type and the third seat type. The seat adjustment device can determine the target seat posture based on the target parameter correction coefficient and the third seat usage preference in the target seat usage preference set.

[0111] In yet another possible implementation, if there is no target seat usage preference set, determine the target seat posture based on the first mapping relationship corresponding to the first seat type and the body feature information.

[0112] Based on this, the present application can determine the matching degree between the body feature information and the first body feature information in the seat usage preference library. When the matching degree is greater than the preset threshold, it indicates that there is a user in the seat usage preference library whose body features are highly similar to those of the target user and their seat usage preferences. Therefore, the target seat posture can be determined based on the seat usage preferences of this user, which can more accurately meet the body needs of the target user and achieve personalized seat adjustment.

[0113] In some embodiments, as Figure 4 shown, it is a seat adjustment interface.

[0114] In a possible implementation, the seat adjustment interface can include seat information of different users. The user can send a seat adjustment instruction to the seat adjustment device through the seat adjustment interface. The seat adjustment device can adjust the corresponding seat based on the seat adjustment instruction.

[0115] In a possible implementation, the seat adjustment interface further includes options such as seat position, position, backrest, leg rest, zero gravity, seat courtesy, quick control, seat comfort, seat position, save, system settings, etc.

[0116] Exemplarily, in combination with Figure 4 , the current seat position is the left side of the second row.

[0117] Figure 5 is a block diagram of a seat adjustment device shown according to an exemplary embodiment. Referring to Figure 5 , the seat adjustment device includes: a determination unit 601, an adjustment unit 602, and an update unit 603.

[0118] In a possible implementation, the determination unit 601 is configured to determine the movement trajectory and action information of the target user through the video information captured by the external camera.

[0119] In a possible implementation manner, the determining unit 601 is further configured to determine the door to be opened by the target user based on the moving trajectory and action information of the target user.

[0120] In a possible implementation manner, the determining unit 601 is further configured to determine the first seat for the target user to take a seat based on the door to be opened.

[0121] In a possible implementation manner, the adjusting unit 602 is configured to, when the target user is a multiple-rider, adjust the posture of the first seat based on the seat usage preference set of the target user.

[0122] In a possible manner, the determining unit 601 is specifically configured to: regard the seats in the cockpit area corresponding to the door to be opened as candidate seats. Determine the first seat from the candidate seats based on the historical number of times the target user has taken a seat on the candidate seats.

[0123] In a possible manner, the determining unit 601 is specifically configured to: regard the seats in the cockpit area corresponding to the door to be opened as candidate seats. When it is determined that there are other users approaching the door to be opened behind the user, regard the candidate seat far from the door to be opened as the first seat.

[0124] In a possible manner, the adjusting unit 602 is specifically configured to: if there is a first seat usage preference information in the seat usage preference set, adjust the posture of the first seat based on the first seat usage preference. If there is no first seat usage preference information in the seat usage preference set, correct the second seat usage preference information in the seat usage preference set, and adjust the posture of the first seat based on the corrected second seat usage preference information.

[0125] In a possible manner, the adjusting unit 602 is specifically configured to: determine a parameter correction coefficient between the first seat type and the second seat type. Determine the corrected second seat usage preference information based on the parameter correction coefficient and the second seat usage preference information.

[0126] In a possible manner, the determining unit 601 is further configured to, when the target user is a first-time rider, determine a target seat posture matching the target user based on the body feature information and the first seat type.

[0127] In a possible manner, the adjusting unit 602 is further configured to adjust the posture of the first seat based on the target seat posture.

[0128] In one possible way, the adjustment unit 602 is specifically configured to: determine whether there is a target seat usage preference set in the seat usage preference library whose matching degree with the body feature information is greater than a preset threshold. If there is a target seat usage preference set, based on the first seat type and the target seat usage preference set, determine the target seat posture.

[0129] In one possible way, the adjustment unit 602 is specifically configured to: if there is no target seat usage preference set, based on the first mapping relationship corresponding to the first seat type and the body feature information, determine the target seat posture.

[0130] In one possible way, the device further includes: an update unit 603, and the update unit is configured to update the seat usage preference information of the target user for the first seat based on the posture information of the first seat after adjustment.
