Hereinafter, the present application will be described in detail with reference to the accompanying drawings and in combination with embodiments.

FIG. 1 is a flowchart illustrating a method 100 of adjusting a seat according to an embodiment. Method 100 may be applicable, for example, to in-vehicle systems. The method 100 will be described in detail below with reference to FIG. 1 .

In the method 100, firstly, the passenger distribution information of the front seat and the rear seat of the vehicle can be acquired in real time through a pre-set passenger positioning device in the vehicle (S110).

In this embodiment, the passenger distribution information on the front seat of the vehicle indicates whether there are passengers on the front seat of the vehicle, and the passenger distribution information on the rear seat of the vehicle indicates whether there is a passenger on the rear seat corresponding to the front seat. In addition, the occupant positioning device in the vehicle may be, for example, a camera, a seat pressure sensor, an ultra-wideband (UWB) high-precision positioning device, and the like. Compared with other positioning technologies, UWB high-precision positioning devices have many advantages such as high positioning accuracy, good security, high transmission rate, large system capacity, low power consumption, and strong anti-interference ability.

In this embodiment, when the occupant locating device in the vehicle is a camera, it is possible to obtain whether there are passengers on the front seat of the vehicle and the corresponding rear seat by photographing the distribution of passengers in the vehicle in real time. In another embodiment, when the passenger positioning device in the vehicle is a seat pressure sensor, it can be determined whether there are passengers on the front seat and the corresponding rear seat of the vehicle through pressure detection. In yet another embodiment, when the passenger positioning device in the vehicle is a UWB high-precision positioning device, the UWB high-precision positioning device can accurately locate the position of the passenger in the vehicle through real-time communication with the passenger's mobile device, thereby judging the location of the vehicle. Whether there are passengers in the front seat and the corresponding rear seat.

As mentioned above, in this embodiment, the function of the positioning device for occupants in the vehicle is to acquire passenger distribution information inside the vehicle in real time. That is to say, as long as the passenger distribution information inside the vehicle can be obtained in real time, those skilled in the art can select any type of passenger positioning device in the vehicle according to needs.

After the passenger distribution information in the vehicle is acquired, a seat adjustment strategy may be determined based on the acquired passenger distribution information (S120).

In this embodiment, the seat that can be adjusted forward and backward can be adjusted according to the seating state of the seat in the vehicle, so that the passengers in the vehicle can obtain a more comfortable seating space. In this embodiment, for the convenience of explanation, the seat adjustment strategy is described in detail by taking a four-seater vehicle in which the front seats can be adjusted as an example, but those skilled in the art can understand that, without departing from the teaching of the present disclosure, this Embodiments of the application may be applied to vehicles with seven seats or to vehicles with any number of seats. Furthermore, embodiments of the present application may be applied to vehicles with adjustable front and rear seats without departing from the teachings of the present disclosure.

The seat adjustment strategy based on passenger distribution information in the vehicle is shown in Table 1 below.

Table 1

In this embodiment, as shown in Table 1, when there is a passenger in the front seat and a passenger in the back seat (case 1) or there is no passenger in the front seat and no passenger in the back seat (case 2), the front seat can automatically move to the middle comfortable position. Location. Here, the intermediate comfort position means a position where the seating space at the front seat is approximately the same as the corresponding seating space at the rear seat. In other words, when the occupant distribution information obtained through the in-vehicle passenger acquisition device indicates that there are passengers in both the front seat and the rear seat, the front seat can automatically move to the middle comfortable position, thereby ensuring the seating of the front seat passengers and the rear seat passengers. The space is roughly the same, so that the passengers in the front seat and the passengers in the rear seat can get a relatively good riding experience. In addition, when the occupant distribution information obtained through the in-vehicle passenger acquisition device indicates that there are no passengers in the front seat or the rear seat, the front seat can automatically move to the middle comfortable position, so that the interior space of the vehicle can be kept reasonable and tidy.

In this embodiment, as shown in Table 1, when there is a passenger in the front seat and no passenger in the rear seat, the front seat can automatically move to the rear position (case 3). Here, the rear position means a position in which the seating space at the front seats is larger than that at the rear seats corresponding thereto. In other words, when the occupant distribution information obtained through the in-vehicle passenger acquisition device indicates that the front seat has passengers and the rear seat does not have passengers, the front seats can be automatically moved to the rear position, so that the passengers in the front seats can obtain more seating space, In order to obtain a better riding experience.

In this embodiment, as shown in Table 1, when there is no passenger in the front seat and there is a passenger in the rear seat, the front seat can automatically move to the front position (case 4). Here, the front position means a position in which the seating space at the front seats is smaller than that at the rear seats corresponding thereto. In other words, when the occupant distribution information obtained through the in-vehicle passenger acquisition device indicates that the front seat has no passengers and the rear seat has passengers, the front seat can automatically move to the front position, so that the passengers in the rear seat can obtain more seating space , so as to obtain a better riding experience.

It should be noted that without departing from the technical spirit of the present disclosure, those skilled in the art can arbitrarily determine the specific settings of the above-mentioned front position, middle comfortable position and rear position.

In the implementation related to FIG. 1 , it is described that the seat adjustment strategy is determined based on passenger distribution information in the vehicle. In another embodiment of the present application, the seat adjustment strategy may be determined according to both the passenger distribution information in the vehicle and the passenger positions outside the vehicle, which will be described in detail below with reference to FIG. 2 .

Thereafter, after determining the corresponding seat adjustment strategy according to the passenger distribution information, the seats of the vehicle may be automatically adjusted based on the determined seat adjustment strategy ( S130 ), so that passengers in the vehicle can obtain a more comfortable riding experience.

In this embodiment, since the occupant positioning device in the vehicle can obtain the passenger distribution information in the vehicle in real time, when the occupant in the vehicle changes the seating position (for example, moves from the left rear seat to the right rear seat), real-time adjustment can be made. Seats to ensure passenger comfort.

In the embodiment of the present application, adjusting the seat of the vehicle based on the seat adjustment strategy may further include: displaying the seat adjustment image on the vehicle-mounted screen, and adjusting the vehicle seat based on the seat adjustment strategy, through the seat The chair adjustment image shows the movement of the seat adjustment. Generally speaking, the vehicle is equipped with a vehicle-mounted screen. After the seat adjustment strategy is determined, the corresponding seat adjustment strategy can be transmitted to the vehicle-mounted screen to display the seat adjustment image on the vehicle-mounted screen, and the seat can be adjusted while adjusting the seat. The movement process of the seat adjustment is displayed in real time through the seat adjustment image. In this way, the seat adjustment process can be displayed more intuitively to passengers, thereby further improving the riding experience.

Generally speaking, after the vehicle seat adjustment is completed, the passenger may need to further adjust the seat. To this end, as shown in FIG. 1 , the method 100 may also optionally include step S140 and/or step S150. In step S140, after the adjustment of the vehicle seat based on the seat adjustment strategy is completed, the seat adjustment system may be displayed on an on-board screen of the vehicle, and the vehicle seat is adjusted based on an instruction received through the seat adjustment system. That is to say, after the vehicle system automatically adjusts the vehicle seat based on the seat adjustment strategy, the seat adjustment system can be displayed on the vehicle screen. At this time, the user can touch the vehicle screen with a part of the body (such as a finger) to realize seat alignment. Manual control of chair position. For example, when the user's finger touches the seat on the seat adjustment system and slides backward, the vehicle seat can be controlled to move to the rear position. In this way, the passenger experience can be further improved.

In step S150 , after the vehicle seat is adjusted based on the seat adjustment strategy, the vehicle seat may be directly adjusted through an instruction from a mobile device communicatively connected to the vehicle system. That is to say, after the vehicle system automatically adjusts the vehicle seat based on the seat adjustment strategy, passengers can send instructions to the vehicle system through their own mobile devices (such as smart phones, smart tablets, etc.), and the vehicle system can Direct control of the adjustment of the vehicle seat. In this way, the passenger experience can be further improved.

It should be noted that those skilled in the art may choose any method to directly control the adjustment of the vehicle seat without departing from the embodiments of the present application, and are not specifically limited to the embodiments described above.

In a real-world scenario, if a passenger wants to get on the bus, the passenger needs to adjust the seat after getting on the bus, which reduces convenience and comfort. Therefore, there is a need for a method that can "predict" that passengers get on the bus and adjust the vehicle seat in advance. This will be described in detail below with reference to FIG. 2 .

FIG. 2 is a flowchart illustrating a method 200 of adjusting a seat according to another embodiment. Method 200 may apply, for example, to an in-vehicle system.

Except for steps S220 and S230 , the method 200 according to the embodiment is substantially the same as the method 100 of the previous embodiment described with reference to FIG. 1 , and any repeated explanations about the same steps above may be omitted or briefly described.

In this embodiment, firstly, the passenger distribution information of the front seat and the rear seat of the vehicle can be obtained in real time through the pre-set passenger positioning device in the vehicle (S210).

Thereafter, the position of the passenger outside the vehicle door can be obtained in real time through the preset positioning device for the passenger outside the vehicle (S220).

In this embodiment, the position of the passenger outside the vehicle door means the position of the passenger around the vehicle (for example, within about 0.1 meters) relative to the vehicle. In addition, the passenger positioning device outside the vehicle may be, for example, a camera, a sensor, a UWB high-precision positioning device, and the like. As mentioned above, compared with other positioning technologies, UWB high-precision positioning devices have many advantages such as high positioning accuracy, good security, high transmission rate, large system capacity, low power consumption, and strong anti-interference ability.

In this embodiment, when the positioning device for passengers outside the vehicle is a camera, the location of the passengers near the vehicle can be obtained by photographing the passengers around the vehicle in real time. In another embodiment, when the passenger positioning device outside the vehicle is a sensor, the position of the passenger near the vehicle can be judged by means of infrared detection or the like. In yet another embodiment, when the positioning device for passengers outside the vehicle is a UWB high-precision positioning device, the UWB high-precision positioning device can accurately locate the position of the passengers outside the vehicle through real-time communication with mobile devices of passengers outside the vehicle.

As mentioned above, in this embodiment, the function of the positioning device for passengers outside the vehicle is to acquire the position of passengers outside the vehicle in real time. That is to say, as long as the position of passengers outside the vehicle can be obtained in real time, those skilled in the art can choose any type of positioning device for passengers outside the vehicle according to needs. In addition, in this embodiment, the above-mentioned positioning device for passengers in the vehicle and the positioning device for passengers outside the vehicle may be an integrated device or a separate device. For example, when the passenger positioning device inside the vehicle and the passenger positioning device outside the vehicle are integrated devices, they may be the same UWB high-precision positioning device that is integrated and installed inside the vehicle.

Thereafter, in response to the occupant's position outside the vehicle door meeting a predetermined condition, a seat adjustment strategy is determined based on the occupant's position outside the vehicle door and the acquired passenger distribution information ( S230 ).

In real-world scenarios, there may be situations where a passing pedestrian is mistakenly identified as a passenger who is about to board the vehicle because the pedestrian is passing by the vehicle. In this embodiment, to solve this problem, specific predetermined conditions are set, and when a person near the vehicle satisfies the predetermined condition, the person is "judged" as a passenger with a tendency to ride. Specifically, the predetermined condition may include that the passenger outside the vehicle door is at a certain distance from the vehicle door and keeps the certain distance for a predetermined time. That is to say, only when a person near the vehicle is at a certain distance from the door of the vehicle and keeps the certain distance for a predetermined time, the person can be "judged" as a passenger who is inclined to ride. In this embodiment, the specific distance from the door of the vehicle may be, for example, about 0.1 to 0.2 meters, and the predetermined time may be, for example, 1 second. For example, when the pedestrian is 0.15 meters away from the front door of the vehicle and keeps the distance for more than 1 second, the pedestrian is determined as a passenger waiting to get on the bus, and the specific location is determined based on the pedestrian's position and passenger distribution in the vehicle as described later. Seat adjustment strategy.

It should be noted that the above specific numerical values are only shown for the purpose of description, and those skilled in the art can understand that any specific distance and predetermined time can be set as required without departing from the teaching of the present disclosure.

The following table 2 shows the seat adjustment strategy determined based on the passenger position outside the car door and the obtained passenger distribution information in response to the passenger position outside the car door meeting the predetermined condition

Table 2

In this embodiment, as shown in Table 2, when it is detected that there is a passenger waiting to board near the front door of the vehicle, there is a passenger in the front seat and a passenger in the rear seat (case 2 in Table 2), or there is a passenger in the front seat and there is no passenger in the rear seat. In the presence of a passenger (case 3 of Table 2), the front seat remains stationary. For example, there is a passenger waiting to board at the front door of the vehicle. At this time, there are already passengers on the front seat inside the vehicle, so that the passenger outside the vehicle cannot take the front seat of the vehicle. Therefore, the seat adjustment strategy in this case is: keep the front seat still.

In addition, when it is detected that there is a passenger waiting to board near the front door of the vehicle, if there is no passenger in the front seat and there is a passenger in the rear seat (case 4 in Table 2), the front seat moves to the middle comfortable position. For example, there is a passenger waiting to board at the front door of the vehicle and there are no passengers on the front seat inside the vehicle and there are passengers on the rear seat. Afterwards, the distribution of passengers inside the vehicle will change to case 1 in Table 1 (that is, both the front and rear seats have passengers), that is, the seat adjustment strategy in this case is: the front seat moves to the middle comfortable position.

In addition, when a passenger waiting to board is detected near the front door of the vehicle, the front seat moves to the rear position when there is no passenger in the front seat and no passenger in the rear seat (case 1 in Table 2). For example, there is a passenger waiting to board at the front door of the vehicle and there is no passenger on the front seat and no passenger on the rear seat inside the vehicle. In this case, the front seat is in the middle comfortable position (see situation 2 in Table 1), so when the passenger boards the vehicle, Afterwards, the distribution of passengers inside the vehicle will change to situation 3 in Table 1 (that is, there are passengers in the front seat and no passengers in the rear seat), that is, the seat adjustment strategy in this case is: the front seat moves to the rear position.

In this embodiment, when it is detected that there are passengers waiting to board near the rear door of the vehicle or when it is detected that there are passengers waiting to board near the front door of the vehicle and there are also passengers waiting to board near the rear door of the vehicle The seat adjustment strategy is similar when there are passengers waiting to board near the front door of the vehicle, so it will be briefly described below.

For example, as shown in Table 2, when it is detected that there is a passenger waiting to board near the rear door of the vehicle, there is a passenger in the front seat and a passenger in the rear seat (case 6 of Table 2) or there is no passenger in the front seat and there is a passenger in the rear seat (Table 2). In the case of 2 and 8), the front seat remains stationary. When it is detected that there is a passenger waiting to board near the rear door of the vehicle, if there is no passenger in the front seat and no passenger in the rear seat (case 5 in Table 2), the front seat moves to the front position. When it is detected that there is a passenger waiting to board near the rear door of the vehicle, when there is a passenger in the front seat and there is no passenger in the rear seat (case 7 in Table 2), the front seat moves to the middle comfortable position.

In addition, as shown in Table 2, when it is detected that there are passengers waiting to board near both the front door and the rear door of the vehicle, there is a passenger in the front seat and a passenger in the rear seat (case 10 in Table 2) or there is no passenger in the front seat and there is no passenger in the rear seat. In the presence of a passenger (case 9 of Table 2), the front seat remains stationary. When it is detected that there are passengers waiting to board near the front door and the rear door of the vehicle, there are passengers in the front seat and no passengers in the back seat (case 11 in table 2) or no passengers in the front seat and passengers in the back seat (case 12 in table 2) The front seats move to the middle comfort position.

Through the above seat adjustment strategies, the vehicle system can predict whether there are passengers waiting to ride and determine the corresponding seat adjustment strategy based on this and the distribution of passengers in the vehicle, thereby further improving the passenger's riding convenience and comfort.

Thereafter, the seat of the vehicle may be automatically adjusted based on the determined seat adjustment strategy (S240).

Thereafter, similar to steps S140 and S150 described with reference to FIG. 1 , when further adjustment of the vehicle seat is required, the seat adjustment system may be displayed on the vehicle's on-board screen, and the vehicle seat may be adjusted based on an instruction received through the seat adjustment system. The seat (S250), or the vehicle seat can be directly adjusted (S260) by an instruction from a mobile device communicatively connected to the vehicle system.

The vehicle seat adjustment strategy determined based on both the location of passengers outside the vehicle and the distribution of passengers inside the vehicle has been described above. Those skilled in the art can understand that without departing from the spirit and scope of the present application, corresponding seat adjustment strategies can be set as required.

FIG. 3 is a diagram illustrating a system 300 for adjusting a vehicle seat according to an embodiment of the present application. The system 300 will be described in detail below with reference to FIG. 3 .

In this embodiment, the in-vehicle occupant positioning device 310 may be set at a predetermined position in the vehicle and configured to acquire passenger distribution information of the front seat and the rear seat in the vehicle in real time. For example, the in-vehicle occupant positioning device 310 may be a camera, a seat pressure sensor, a UWB high-precision positioning device, etc. as described above. The processor 320 may be in communication with the in-vehicle occupant positioning device 310 and configured to determine a seat adjustment strategy based on the acquired passenger distribution information and adjust the vehicle seats based on the seat adjustment strategy. A specific seat adjustment strategy is similar to that described above with reference to FIG. 1 , and thus a detailed description thereof will be omitted.

In this implementation manner, the mobile device 330 may be, for example, a smart phone, a smart tablet, and the like. Mobile device 330 may be communicatively coupled to processor 320 . In addition, the processor 320 may also be configured to directly adjust the vehicle seat based on the instruction received through the mobile device 330 after the vehicle seat is adjusted based on the seat adjustment strategy. That is, the passenger can communicate an instruction to the processor 320 through the mobile device 330 carried by the passenger, and the processor 320 can directly control the adjustment of the vehicle seat based on the instruction.
