[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The method of adjusting the seat back angle by using the physical buttons on the side of the seat is currently a common method of adjusting the seat back angle in vehicles. However, in this solution, due to the limited space in the vehicle, it is often inconvenient for users to look for the physical buttons on the side of the seat, or it is difficult for users to see the physical buttons when they look for them sideways. As a result, when users adjust the seat back angle, they often have to look for the physical buttons on the side of the seat, which makes it inconvenient for users to adjust the seat back angle.

[0039] In order to facilitate users to adjust the seat back angle, some vehicles are equipped with corresponding virtual buttons on the central control screen, and users can adjust the seat back angle by clicking on the virtual buttons. However, in this solution, when adjusting the seat back angle, users need to find the relevant virtual buttons on the central control screen that is far away from them, and constantly lean forward to touch the virtual buttons, and then lean back to feel whether the back angle is appropriate. This is a complex operation. Therefore, this solution also has the problem of inconvenient adjustment for users. In addition, some vehicles are equipped with voice control modules, and users can adjust the back angle of the target seat by sending back angle adjustment instructions to the voice control module. However, this solution is difficult to meet the needs of users with language barriers or users who are not convenient to speak to adjust the seat back angle.

[0040] In summary, the method of adjusting the seat back angle by the physical buttons on the side of the seat and the virtual buttons on the central control screen can meet the needs of ordinary users (including users with language barriers or users who are not convenient to speak) for adjusting the seat back angle, and because the buttons are not easily touched by users, this solution is not likely to cause the seat back angle to be adjusted due to the user's accidental touch of the button, but there is a problem of inconvenient adjustment, and the method of adjusting the seat back angle by voice control can improve the convenience of adjustment and is not prone to accidental adjustment, but it is difficult to meet the needs of users with language barriers or users who are not convenient to speak for adjusting the seat back angle. It can be seen that the above solution has the problem of difficulty in taking into account convenience, accuracy and versatility.

[0041] Based on this, the present invention provides a seat back angle adjustment method, device and vehicle, which can take into account convenience, accuracy and versatility. The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings.

[0042] Figure 1 Schematic diagram of the structure of a seat back angle adjustment device provided by an embodiment of the present invention. Figure 1 As shown, the device includes: an instruction receiving device 11, a first pressure detection device 12, a second pressure detection device 13 and a controller 14.

[0043] The first pressure detection device 12 and the second pressure detection device 13 are both arranged on the backrest of a target seat of the vehicle, and the target seat is a seat with an adjustable backrest angle.

[0044] The instruction receiving device 11 , the first pressure detecting device 12 and the second pressure detecting device 13 are respectively connected to the controller 14 for communication.

[0045] The instruction receiving device 11 is used for sending an adjustment instruction to the controller 14 in response to a manual adjustment operation of a user.

[0046] The controller 14 is used to adjust the backrest angle of the target seat according to the pressure data sent by the first pressure detection device 12 and the second pressure detection device 13 when receiving the adjustment instruction.

[0047] The embodiment of the present invention adopts the above-mentioned technical solution. Since the controller is used to adjust the backrest angle of the target seat according to the pressure data sent by the first pressure detection device and the second pressure detection device when the adjustment instruction sent by the user is received through the instruction receiving device, that is, the controller 14 will adjust the backrest angle of the target seat only when it receives the adjustment instruction sent by the user through the instruction receiving device 11, so that the present invention can avoid adjusting the backrest angle when the user accidentally touches the pressure detection device, thereby improving the accuracy of the adjustment result.

[0048] Furthermore, in the process of adjusting the backrest angle of the present invention, since the user can use the back pressing pressure detection device to adjust the backrest angle, the user can avoid the complex operation of looking for the relevant virtual buttons on the central control screen far away from the user, constantly leaning forward to touch the virtual buttons, and leaning back to feel whether the backrest angle is appropriate. At the same time, the user can avoid looking for the relevant physical buttons beside the seat, which makes the present invention more convenient to adjust. Furthermore, since the user only needs to use the back pressing pressure detection device when adjusting the backrest angle, which is something that ordinary users can do, the present invention improves versatility.

[0049] In summary, the present invention can avoid adjusting the backrest angle when the user accidentally touches the pressure detection device, so that the present invention improves the accuracy of the adjustment result; and, because the user can use his back to press the pressure detection device to achieve the backrest angle adjustment, the present invention improves the convenience and versatility of adjustment.

[0050] In the embodiment of the present invention, the target seat may be a main driving seat.

[0051] Specifically, when the user adjusts the backrest angle of the target seat through the aforementioned physical buttons or virtual buttons during driving, the user needs to free up one hand to perform the adjustment operation, so that the user needs to keep controlling the steering wheel with one hand for a long time, which reduces driving safety; and when adjusting the backrest angle of the target seat through the virtual buttons set on the central control screen, the user needs to shift his or her eyes, which further reduces driving safety.

[0052] In the embodiment of the present invention, since the controller is used to adjust the backrest angle of the target seat according to the pressure data sent by the first pressure detection device and the second pressure detection device when the adjustment instruction sent by the user is received through the instruction receiving device, that is, the controller 14 will adjust the backrest angle of the target seat only when it receives the adjustment instruction sent by the user through the instruction receiving device 11, the present invention can avoid adjusting the backrest angle when the user accidentally touches the pressure detection device, thereby improving driving safety.

[0053] Furthermore, during the process of adjusting the backrest angle of the present invention, since the user does not need to perform other manual adjustment operations except sending adjustment instructions, and will not divert his or her eyes for a long time, when adjusting the backrest angle during driving, both hands will not leave the steering wheel for a long time, thereby further improving driving safety.

[0054] In the embodiment of the present invention, the controller 14 can be specifically used for:

[0055] When it is determined based on the pressure data that the first pressure received by the first pressure detection device meets the preset pressure requirement, the backrest of the target seat is controlled to be adjusted in the first direction; and when it is determined based on the pressure data that the second pressure received by the second pressure detection device meets the preset pressure requirement, the backrest of the target seat is controlled to be adjusted in the second direction.

[0056] Specifically, controlling the target seat backrest to adjust in the first direction may specifically be adjusting the target seat backrest toward the user (i.e., the front direction of the vehicle), and controlling the target seat backrest to adjust in the second direction may specifically be adjusting the target seat backrest toward the user (i.e., the rear direction of the vehicle).

[0057] In the embodiment of the present invention, when the pressure on the first pressure detection device or the second pressure detection device meets the preset pressure requirement, the backrest of the target seat is controlled to be adjusted in the corresponding direction. If the pressure on the pressed pressure detection device does not meet the preset pressure requirement, the backrest of the target seat is prohibited from being controlled to be adjusted in the corresponding direction. In this way, adjustments that are not subjectively required by the user are avoided in some special cases, which may sometimes cause harm to the user's body. For example, when a vehicle rear-end collision occurs, the user tends to apply greater pressure to the pressure detection device. If the seat back angle is adjusted toward the front of the vehicle at this time, the user may be squeezed by the steering wheel and the seat back, thereby causing harm to the user's body.

[0058] In the embodiment of the present invention, the preset pressure requirement can be freely set according to the actual situation. In a specific example, if the first pressure or the second pressure is within the preset pressure range, it is determined that the pressure within the preset pressure range meets the preset pressure requirement. In another specific example, if the change rate of the first pressure or the second pressure is less than the preset rate threshold, it is determined that the pressure less than the preset rate threshold meets the preset pressure requirement.

[0059] In an embodiment of the present invention, the instruction receiving device 11 is used to respond to the user's manual adjustment operation and send an adjustment instruction to the controller 14 so that the controller 14 adjusts the seat back angle according to the adjustment instruction. Therefore, the structure and setting position of the instruction receiving device 11 are diverse and can implement the present application.

[0060] Based on this, in a specific example, the instruction receiving device 11 can be a virtual button on the central control screen. After the user clicks the virtual button, the controller 14 can receive the adjustment instruction sent by the user.

[0061] In another specific example, the instruction receiving device 11 may be a push switch, and the push switch may be disposed at a location such as a vehicle dashboard.

[0062] In the embodiment of the present invention, the push switch may also be arranged on the steering wheel of the vehicle.

[0063] Specifically, the push switch is arranged at a position where the user can conveniently press the push switch while keeping both hands tightly gripping the steering wheel. In this way, when the user presses the push switch during driving, the user can keep both hands tightly gripping the steering wheel, thereby improving driving safety.

[0064] In a specific example, Figure 2 FIG. 1 is a schematic diagram of the position of a push-type switch provided by an embodiment of the present invention. Figure 2 As shown, the push switch can be set at position 21 or position 22.

[0065] In the embodiment of the present invention, the controller 14 can be specifically used to adjust the backrest angle of the target seat according to the pressure data sent by the first pressure detection device 12 and the second pressure detection device 13 when it is determined that the push switch 11 is in a pressed state.

[0066] Here, the controller 14 is specifically used to adjust the backrest angle of the target seat according to the pressure data when it is determined that the push switch 11 is in a pressed state. That is, when the user adjusts the seat back angle, the user is required to maintain the state of pressing the push switch. If the user stops pressing, the controller 14 does not adjust the seat back angle. In this way, when the user accidentally touches the push switch, the controller 14 does not continuously adjust the seat back angle according to the pressure data.

[0067] In the embodiment of the present invention, the controller 14 is further configured to control the instruction receiving device 11 to enter a working state when it is determined that someone is sitting in the target seat.

[0068] Specifically, only when the instruction receiving device 11 enters the working state can the user send the adjustment instruction to the controller 14 through the instruction receiving device 11. The embodiment of the present invention controls the instruction receiving device 11 to enter the working state when it is determined that someone is sitting in the target seat, so that the embodiment of the present invention can prevent the controller 14 from adjusting the seat back angle according to the pressure data when a person who is not sitting in the target seat accidentally touches the instruction receiving device 11.

[0069] In the embodiment of the present invention, the controller 14 can specifically calculate the pressure borne by the hip support structure through the detection data sent by the third pressure detection device located on the hip support structure of the target seat, and then judge whether there is a person sitting on the target seat according to the pressure borne by the hip support structure. Among them, when the target seat is the main driver's seat, the third pressure detection device can be a pressure sensor in the current SBR (Safety Belt Reminder). And, it should be noted that both the first pressure detection device and the second pressure detection device can be pressure sensors.

[0070] In the embodiment of the present invention, the arrangement positions of the first pressure detection device 12 and the second pressure detection device 13 can be freely set according to actual conditions, as long as the user can adjust the seat back angle by pressing the first pressure detection device 12 or the second pressure detection device 13. It should be noted that the distance between the first pressure detection device 12 and the second pressure detection device 13 should be greater than the preset distance threshold, so that when the user presses one of the pressure detection devices, the other pressure detection device will not be accidentally touched.

[0071] Figure 3Schematic diagram of the installation position of a pressure detection device provided by an embodiment of the present invention. Figure 3 In a specific example, the first pressure detection device 12 is specifically arranged in the first area 32 of the backrest; the first area 32 is used to support the left shoulder of the user; the second pressure detection device 13 is specifically arranged in the second area 31 of the backrest; the second area 31 is used to support the right shoulder of the user.

[0072] In another specific example, the first pressure detection device 12 is specifically disposed in the first headrest region 33 of the backrest, and the second pressure detection device 13 is specifically disposed in the second headrest region 34 of the backrest.

[0073] In an embodiment of the present invention, the first pressure detection device 12 and the second pressure detection device 13 can be arranged on the same horizontal line. In this way, when the user determines the position of one of the pressure detection devices, the user can quickly determine the position of the other pressure detection device based on the position of the pressure detection device, thereby improving the efficiency of adjusting the seat back angle.

[0074] Based on a general inventive concept, the present invention further provides a seat back angle adjustment method, which is applied to the seat back angle adjustment device as described in the above embodiment. Figure 4 FIG. 1 is a flow chart of a method for adjusting the seat back angle provided by an embodiment of the present invention. Figure 4 As shown, this process includes:

[0075] Step 401: The controller receives an adjustment instruction sent by a user through an instruction receiving device.

[0076] Specifically, the instruction receiving device may send an adjustment instruction to the controller according to a manual adjustment operation of the user.

[0077] Step 402: The controller controls the first pressure detection device and the second pressure detection device to enter a working state according to the adjustment instruction.

[0078] Step 403: The first pressure detection device and the second pressure detection device collect pressure data and send the collected pressure data to the controller.

[0079] Step 404: The controller adjusts the backrest angle of the target seat of the vehicle according to the pressure data.

[0080] Specifically, the controller may adjust the working state of the vehicle's backrest angle adjustment motor according to the pressure data to adjust the backrest angle of the target seat of the vehicle.

[0081] Figure 5 FIG. 1 is a flow chart of another method for adjusting the seat back angle provided by an embodiment of the present invention. Figure 5As shown, this process includes:

[0082] Step 501: When the controller determines that someone is sitting in the main driver's seat, it controls the command receiving device to enter a working state, and the command receiving device is a push switch set on the steering wheel.

[0083] Step 502: When the controller determines that the push switch is in a pressed state, the controller controls the first pressure detection device and the second pressure detection device to enter a working state.

[0084] Step 503: After the first pressure detection device and the second pressure detection device enter the working state, the two pressure detection devices collect pressure data and send the collected pressure data to the controller.

[0085] Step 504: When the controller determines based on the pressure data that the first pressure received by the first pressure detection device meets the preset pressure requirement, the controller controls the backrest of the main driver's seat to adjust toward the first direction; and when the controller determines based on the pressure data that the second pressure received by the second pressure detection device meets the preset pressure requirement, the controller controls the backrest of the main driver's seat to adjust toward the second direction.
