[0064] The present application will be further described in detail below with reference to the accompanying drawings, see as Figures 1 to 6 Description.

[0065] A vehicle seat control method of the present application is applied to a child safety seat, which has a rotating function. The seat has a base at the bottom, and a rotating mechanism is arranged on the base. A driving mechanism is used to drive the seat to rotate. For the rotating principle of the seat, reference can be made to the prior art Chinese patent with application No. CN202210140659.1, which will not be described here.

[0066] Sensors are arranged on the left and right sides of the seat. The sensors are distance measuring sensors, which are used to measure the distance between the seat and the door. The sensors can be laser distance measuring sensors, infrared distance measuring sensors, ultrasonic distance measuring sensors, etc. The type of the distance measuring sensor is not limited, as long as it meets the distance measuring function. The sensor used in the present application measures the distance between the door and the seat in real time after being started, and transmits the measured distance to the background processing unit. The background processing unit controls the seat to automatically rotate based on the distance data.

[0067] Some embodiments of the vehicle seat control method are provided below, so that the seat has an automatic rotating function. When the user needs to use the child seat, the seat can automatically rotate to a preset position, which is convenient for the user to use the seat.

[0068] Embodiment one

[0069] As Figure 1 shown, a flowchart of a vehicle seat control method of an embodiment of the present application is shown. The method is applied to a child safety seat. The method includes:

[0070] After the door is opened, the distance X between the door and the seat is obtained;

[0071] It is determined that the value of the distance is greater than a preset threshold X1;

[0072] The seat is controlled to execute to a preset position.

[0073] Here, the preset threshold value indicates that after the door is opened to a certain angle, the distance between the door and the seat can indicate that the user opens the door to a sufficient extent, has the intention to place the child on the seat or take the child away from the seat; it should be noted that whether the door is opened or not, the sensor always detects the distance X between the door and the seat in real time, and when the door is opened, X changes, which is not a constant value, and when X≥X1, it indicates that the position of the opened door is large, and it is not accidentally opened, and the user has the need to use the seat, so the seat is automatically rotated to a preset position, that is, the seat is rotated from the direction facing the inside of the car to the direction facing the door, greatly facilitating parents to place children on the seat or take children away from the seat. The preset position includes a rotation direction and a rotation angle, which are set according to actual conditions.

[0074] Embodiment two

[0075] This embodiment is based on embodiment one.

[0076] In this embodiment, the seat control method for a vehicle includes:

[0077] In the door closed state, the distance between the door and the seat obtained by the sensor is an initial distance X0;

[0078] A preset threshold value X1 is determined according to the initial distance;

[0079] After the door is opened, the distance X between the door and the seat is obtained;

[0080] It is determined that the value of the distance is greater than or equal to the preset threshold value X1;

[0081] The seat is controlled to execute to a preset position.

[0082] As Figure 2 shown, in this embodiment, the distance between the door and the seat in the door closed state is an initial distance X0, which is a constant value, and the initial distance is used to determine whether the door is opened, and when X>X0, it indicates that the door is opened, and the next step can be executed;

[0083] Since the installation position of the seat in the car is different, the initial distance X0 is different, so the initial distance needs to be measured, and since the model of each car is different and the habit of opening the door of parents is different, the preset threshold value X1 needs to be determined according to the initial distance X0, wherein X1>X0; The technical scheme of this embodiment can strengthen the applicability and flexibility of the seat, and can be adjusted according to different actual conditions to adapt to different users, which is more intelligent and convenient.

[0084] It should be noted that X1-X0>5cm, so that the automatic rotation function of the seat is more accurate, and the situation that the seat rotates immediately after the door is opened by mistake is avoided.

[0085] Embodiment three

[0086] This embodiment can be extended on the basis of embodiment one.

[0087] In this embodiment, the vehicle seat control method further comprises:

[0088] After the door is opened, the distance X between the door and the seat is obtained;

[0089] determining that the value of the distance is greater than or equal to a preset threshold X1;

[0090] waiting for a first preset time T1;

[0091] controlling the seat to execute to a preset position.

[0092] As Figure 3 shown, in this embodiment, after determining X≥X1, the seat is automatically rotated to the preset position after waiting for a first preset time T1 seconds. The advantage of this setting is that it can give parents enough operating time after the door is opened, so that parents can check the condition of the seat or have enough time to hold the child or prepare to hold the child, and then the seat is rotated towards the door direction, thereby facilitating the user and reducing the safety hazard problem of the child after the seat is automatically rotated to the specified position after the door is opened, and increasing the safety of use.

[0093] In this embodiment, the first preset time T1 is 1-5 seconds, and the specific time can be selected according to actual needs, and T1 time can also be freely set through the control panel; in this embodiment, T1 is preferably 2S.

[0094] It should be noted that this embodiment can also be extended on the basis of embodiment two.

[0095] Embodiment four

[0096] This embodiment is extended on the basis of embodiment one.

[0097] In this embodiment, the vehicle seat control method further comprises:

[0098] After the seat is installed, the left and right distances between the door and the seat are obtained by the sensors on both sides of the seat in the closed state of the door;

[0099] determining the installation position of the seat in the vehicle according to the size ratio of the left and right distances;

[0100] or,

[0101] The installation position of the seats inside the vehicle is manually set.

[0102] like Figure 4 As shown, in this embodiment, sensors for measuring the distance between the car door and the seat are installed on both sides of the seat. After the seat is installed, with the car door closed, the sensors on both sides of the seat obtain the distance between the seat and the car door on both sides. Based on the comparison between the distance on the left and the distance on the right, the system automatically determines the installation position of the seat in the car. The seat will execute according to the program set by the system, including the rotation direction and rotation angle of the seat.

[0103] Alternatively, the user can manually set the seat's installation position in the vehicle. After the seat is installed, the user can determine and confirm the installation position on the control panel that connects to and controls the seat. For example, the user can choose to place the seat on the left or right side of the vehicle. After the user selects the installation position, the seat can perform subsequent procedures according to the selected position. For example, the user can select the seat's rotation direction, i.e., turning left or right, and can set the rotation angle. Most rotation angles are 90 degrees, but users can flexibly set them according to the installation position and the situation in the vehicle.

[0104] The technical solution of this embodiment can enhance the applicability and flexibility of the seat, and can be adjusted according to different actual situations to suit different users, making it more intelligent and convenient.

[0105] It should be noted that this embodiment can be extended based on either embodiment two or embodiment three.

[0106] Example 5

[0107] This embodiment can be extended based on any one of the embodiments from Embodiment 1 to Embodiment 4.

[0108] In this embodiment, the seat is connected to a control panel for controlling the seat mode. The control panel can be a mobile APP interactive page or a computer interactive page, or it can be a control panel directly set on the seat. Users can control the seat through the control panel, such as selecting the seat mode. The seat has different execution programs for different modes. Users can use the seat by selecting different modes to meet different user needs.

[0109] The method further includes:

[0110] Once the seat is set to automatic mode, it enters automatic control mode and can automatically rotate to face the door and automatically return to its original position.

[0111] or,

[0112] determining the seat as the manual mode, the seat entering the manual control mode, the seat being able to be manually rotated towards the door direction and manually rotated to reset;

[0113] or,

[0114] determining the seat as the semi-automatic mode, the seat entering the semi-automatic control mode, the seat being able to be automatically rotated towards the door and manually rotated to reset.

[0115] In the embodiment, in the automatic mode, the seat is completely automatically operated according to the program, including automatic detection of the seat, automatic judgment of whether to rotate, automatic rotation towards the door or automatic rotation to reset, and the seat has high intelligence and is convenient;

[0116] When the seat is in the manual mode, the program of the automatic mode of the seat is no longer executed, the automatic detection and automatic rotation function of the seat are stopped, and the seat can only be rotated by the user himself, such a mode can improve safety, and for children who need to be taken care of, the seat is completely controlled by the user manually, which can improve the safety of using the seat and make the user more at ease;

[0117] When the seat is in the semi-automatic mode, when the door is opened and meets the rotation of the seat towards the door direction, the seat can automatically detect the distance between the door and the seat and judge whether the automatic rotation condition is met, and when the rotation condition is met, the seat can be automatically rotated towards the door direction; but when the seat is reset, the seat can only be manually rotated to reset by the user; the advantage of such a mode is that it has certain safety performance and certain intelligence, and is more flexible.

[0118] It should be noted that the embodiment is selected before the seat is rotated and used.

[0119] Embodiment six

[0120] The embodiment can be expanded on the basis of embodiment five.

[0121] In the embodiment, the reset button is arranged on the seat, the reset button can be arranged on the side of the seat, when the child sits on the seat, the reset button cannot be easily touched by the child and cannot be blocked by the child, and the user can conveniently touch and press the reset button.

[0122] After the seat is controlled to execute to the preset position, including:

[0123] pressing the reset button, the seat being rotated to reset;

[0124] or,

[0125] manually rotating the seat to reset;

[0126] or,

[0127] The voice controls the seat to rotate back to the original position.

[0128] Or,

[0129] The control panel controls the seat to rotate back to the original position.

[0130] As Figure 5 shown, in this embodiment, when the seat rotates towards the door direction, the door is opened at this time, and after the user places the child on the seat or takes the child away from the seat, the user presses the reset button, and the seat rotates back to the original position, i.e., the seat rotates towards the inside of the car; or the user can rotate the seat towards the inside of the car by himself; or the seat is controlled to rotate back to the original position by voice, of course, the seat is also connected with a voice recognition detector, which can detect the user's output instruction and transmit it to the control background, and the control background outputs the instruction of rotating back to the original position to the seat, and the related technology of voice recognition exists widely in the prior art, which will not be described here; in addition, the seat can also be controlled to rotate back to the original position by the control panel, and the advantage of the control panel is that it can remotely control the seat without the need to manually rotate, which is more time-saving, labor-saving and convenient. The advantage of the embodiment is that for the user, there is enough time to handle the child and then choose when to rotate the seat back to the original position, which increases the user's monitoring and control of the seat rotating back to the original position, greatly reduces the safety hidden danger of the child on the seat, and makes the user use the seat more at ease.

[0131] Embodiment seven

[0132] This embodiment is further developed on the basis of embodiment five.

[0133] In this embodiment, after the seat is controlled to execute to the preset position, including:

[0134] Waiting for a second preset time T2;

[0135] The distance X between the door and the seat is obtained;

[0136] When the difference ΔX between the distance X and the initial distance X0 is equal to the limit threshold X2, the seat automatically rotates back to the original position;

[0137] Or,

[0138] When the difference ΔX between the distance X and the initial distance X0 is less than or greater than the limit threshold X2, the seat remains in the current state.

[0139] As Figure 6As shown, in the present embodiment, when the seat is rotated towards the door direction, the user uses the seat, and by setting the second preset time T2, enough time for the user to use the seat is reserved, and in this period of time, the user can place the child on the seat or take the child away from the seat. In the second preset time T2, the sensor measures the distance between the door and the seat, which has a greater impact, so that the seat is rotated towards the door and waits for the second preset time T2 before re-executing the seat rotation reset program.

[0140] In the present embodiment, the step of rotating the seat back to the original position includes first waiting for T2, then comparing the obtained distance X with X0, obtaining the difference AX between X and X0, and if the difference AX is within the preset limit threshold X2, i.e. AX=X2, it means that the condition for automatic rotation of the seat back to the original position is met, and the seat is automatically rotated back to the original position. If the difference AX is greater than or less than the limit threshold X2, i.e. AXX2 or AX>X2, the seat remains in the current state, i.e. continues to wait for T2, and repeats the above steps. In the present embodiment, the purpose of setting the limit threshold is that when the sensor detects the distance between the seat and the door after the door is closed, there may be slight shaking or minor errors due to debris, and when the measured distance is based on the initial distance and falls within the limit threshold, it can be considered as the door being closed, so the seat can be rotated back to the original position. By setting the limit threshold, the accuracy of the seat rotation can be improved, and the influence of errors on the seat rotation back to the original position can be reduced.

[0141] It should be noted that in the present embodiment, when the seat is rotated towards the door direction, the edge of the seat will not exceed the body of the vehicle, that is, whether the seat is rotated or not will not affect the closing and opening of the door.

[0142] In the present embodiment, T2 can be set between 5S and 60S, and the specific value can be set according to actual use, and T2 can also be freely set through the control panel.

[0143] Preferably, T2 is 10S.

[0144] Further, after obtaining the initial distance, the method comprises:

[0145] Determining a limit threshold according to the initial distance.

[0146] In the embodiment, the limit threshold X2 is an interval, i.e., a continuous range of values, X2=[-a,+a] mm; X-X0=∆X, when ∆X<-a mm or ∆X>+a mm, the seat remains in the current state and continues to wait for a time T2; and the limit threshold is set to X2=[-a,+a] mm, so that within the range, it can be regarded as a normal measurement error, i.e., the distance within the range is determined as the car door being in the closed state, which can effectively reduce the influence of noise, so that the slight shaking of the seat or the car door or the appearance of the small error of sundries does not cause unnecessary influence on the seat rotation function, and the accuracy of the seat rotation is improved.

[0147] Further, 1 mm≤a≤10 mm, i.e., the maximum range of X2 is [-10,+10] mm, and the minimum range is [-1,+1] mm, that is, when the distance between the sensor and the seat is less than or more than the initial distance by 1 mm to 10 mm, it can be regarded as the seat being in the closed state; of course, the specific value of a can be selected according to the actual situation of the vehicle.

[0148] Preferably, a is 10, i.e., X2=[-10,+10] mm.

[0149] Embodiment Eight

[0150] The embodiment is further developed on the basis of Embodiment Six.

[0151] In the embodiment, after the seat rotation is controlled to reset, the following steps are included:

[0152] The sensor obtains the distance between the car door and the seat.

[0153] According to the comparison of the distance and the initial distance, it is determined whether the car door is closed.

[0154] When the car door is not closed, the seat remains in the current state, and the seat does not perform the action of rotating towards the car door when the car door is opened.

[0155] In the embodiment, after the seat is rotated to reset, the distance between the door and the seat is first detected, and by comparing the distance with the initial distance, if the distance is greater or smaller than the initial distance, it is determined that the door is not closed, and at this time, the seat remains in the current state, and the next command is not executed, i.e., the command of re-detecting whether the door is opened to determine whether the seat is rotated is not executed. The purpose is that when the user manually controls the seat to reset, after the seat is rotated to reset, the user can still be located between the seat and the door, and can not close the door immediately after the seat is rotated to reset, so that after the seat is rotated to reset, the user will leave from between the door and the seat, and the distance between the door and the seat will be re-executed in the judgment program of the seat rotation towards the door, and the error caused by the large distance between the door and the seat after the user leaves between the seat and the door will reduce the accuracy of the seat rotation.

[0156] Further, referring to the setting of the limit threshold value in Embodiment Seven, in the embodiment, in the determination of whether the door is closed, specifically comprising:

[0157] when the difference AX between the distance X and the initial distance X0 is equal to the limit threshold value X2, it is determined that the door is in the closed state;

[0158] when the difference AX between the distance X and the initial distance X0 is less than or greater than the limit threshold value X2, it is determined that the door is in the open state.

[0159] By introducing the limit threshold value X2, the error influence on the determination of whether the door is closed is eliminated, so as to improve the control accuracy of the seat rotation.

[0160] Further, in the determination of whether the door is closed according to the comparison of the distance with the initial distance, specifically comprising:

[0161] within the continuous time T3, it is determined that the distance X remains unchanged, and the door is in the closed state.

[0162] By continuously detecting the distance X between the door and the seat within the continuous time T3, when the continuously obtained distance X within the T3 time remains unchanged, it is indicated that the user is less likely to be between the door and the seat, and the door can be determined to be in the closed state, so as to reduce the error influence.

[0163] Further, T3 can be set within 1S-9S.

[0164] Preferably, T3=5S.

[0165] Embodiment Nine

[0166] The embodiment is further developed on the basis of any one of Embodiments One to Five.

[0167] In the embodiment, the sensor is arranged on the base of the seat, and the sensor does not rotate with the seat. Two sensors can be arranged, respectively on opposite sides of the seat facing the door, and the sensor is arranged on the side wall of the base of the seat, and the base has a mechanism for driving the seat to rotate, and the base does not rotate when the seat rotates, so that the sensor also remains stationary, so that the initial distance between the door and the seat measured by the sensor is unchanged regardless of the rotation of the seat, so that the subsequent control program of the seat is relatively simple, cost is saved, and control is facilitated, and control accuracy is improved.

[0168] The application is described in detail above, and the principles and implementation modes of the application are described by using specific examples. The above description of the embodiments is only used to help understand the application and the core idea. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the application without departing from the principles of the application, and these improvements and modifications also fall within the protection scope of the claims of the application.
