[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and features in different embodiments may be combined with each other.

[0037] Figure 1 The main steps of the method for providing vehicle services based on occupant posture are shown; Figure 1 As shown, the method for providing vehicle services based on passenger posture of the present invention includes:

[0038] S110, determining the occupant's posture in response to the capacitance detection value and angle detection value of the seat and the webbing pull-out length detection value of the seat belt; wherein the capacitance detection value is obtained by detection of capacitance sensor pads arranged in the backrest area, lumbar area and seat area of ​​the seat.

[0039] The seat back area, lumbar area and seat surface area correspond to the back, waist and buttocks of the human body respectively. The capacitive sensor pads are arranged in the seat back area, lumbar area and seat surface area to be distributed in various positions of the seat according to the characteristics of the human body. They can detect whether the back, waist, buttocks and other body parts of the human body are in contact with and pressed against the seat, thereby helping to determine the occupant's posture.

[0040] The angle detection value of the seat can be obtained by the Hall sensor. The seat belt webbing extension length detection value can be obtained by the seat belt webbing displacement sensor. Combining the seat capacitance detection value and the angle detection value and the seat belt webbing extension length detection value, the various postures of the occupant, such as sitting, lying, leaning forward, and sideways, can be accurately determined.

[0041] S120, determining a triggering strategy for a safety protection device of the vehicle according to the occupant's posture; wherein the safety protection device includes a seat belt and an airbag.

[0042] Under different occupant posture conditions, the triggering strategies of safety protection devices such as seat belts and airbags are different. This can protect the safety of occupants in a targeted manner, provide high-quality safety services, and meet user needs.

[0043] The method of providing vehicle services based on occupant posture of the present invention can be used alone as a vehicle safety trigger strategy, or can be used as a supplement to the vehicle safety trigger strategy to provide further targeted safety protection for special occupant postures based on conventional safety trigger strategies.

[0044] Figure 2 The steps of determining that the occupant is in a forward leaning posture and the corresponding safety triggering strategy are shown. Figure 3 The figure shows that the occupant is in a forward leaning position; wherein, Figure 3 The seat 30 is shown in a lying position, but is not limited thereto.

[0045] Combination Figures 1 to 3 As shown, in some embodiments, determining the occupant posture includes:

[0046] S210, when the capacitive sensor pad 31a arranged in the seat area detects a capacitance value, the capacitive sensor pad 31c arranged in the backrest area does not detect a capacitance value, and the webbing pull-out length detection value is greater than the standard pull-out length corresponding to the angle detection value, it is determined that the occupant 38 is in a forward leaning posture; wherein each angle detection value has a corresponding standard pull-out length representing that the occupant 38 is in a standard posture.

[0047] The capacitance sensor pad 31 a arranged in the seat surface area detects a capacitance value, while the capacitance sensor pad 31 c arranged in the backrest area does not detect a capacitance value, indicating that at least the backrest area of ​​the seat 30 is not pressed.

[0048] Each angle detection value has a corresponding standard extension length representing that the occupant is in a standard posture, which may specifically refer to setting one or more angle distinction values ​​for the seatback angle of the seat 30 .

[0049] For example, a 45° angle is set as the angle distinction value. When the backrest angle of the seat 30 is greater than the angle distinction value, the seat 30 is regarded as being in a lying position. When the angle detection value is greater than the angle distinction value, the webbing of the safety belt has a corresponding first standard pull-out length that indicates that the occupant is in a standard lying position; when the backrest angle of the seat 30 is less than or equal to the angle distinction value, the seat 30 is regarded as being in a sitting position. When the backrest angle of the seat 30 is less than or equal to the angle detection value of the angle distinction value, the webbing of the safety belt has a corresponding second standard pull-out length that indicates that the occupant is in a standard sitting position. The first standard pull-out length is less than the second standard pull-out length. The specific values ​​of the first standard pull-out length, the second standard pull-out length, and the angle distinction value can be set as needed. For example, the first standard pull-out length is 70 cm, the second standard pull-out length is 90 cm, and the angle distinction value is 110°, but this is not limited thereto.

[0050] For another example, multiple angle distinction values ​​may be set, such as setting an angle of 150° as the first angle distinction value and an angle of 120° as the second angle distinction value. When the backrest angle of the seat 30 is greater than the first angle distinction value, the seat 30 is deemed to be in a lying state, and a standard lying extension length of the seat belt corresponding to the situation greater than the first angle distinction value is set; when the backrest angle of the seat 30 is less than the first angle distinction value and greater than the second angle distinction value, the seat 30 is deemed to be in a slightly lying state, and a standard slightly lying extension length of the seat belt in the slightly lying state is set; when the seat 30 is less than the second angle distinction value, the seat 30 is deemed to be in a normal sitting state, and a standard sitting extension length of the seat belt in the normal sitting state is set. When the detected value of the pulled-out length of the seat belt 33 is greater than the standard pulled-out length corresponding to the angle detection value of the seat 30, combined with the detection results that the capacitive sensor pad 31a arranged in the seat area detects a capacitance value and the capacitive sensor pad 31c arranged in the backrest area does not detect a capacitance value, it can be determined that there is indeed an occupant 38 on the seat 30 and is in a forward leaning position, eliminating the possibility of misidentification caused by other objects placed on the seat 30.

[0051] In addition, a corresponding detection threshold may also be set for the capacitance detection value. The capacitance sensor pad is considered to have detected the capacitance value only when the capacitance value detected by the capacitance sensor pad is greater than the set detection threshold, thereby eliminating misidentification caused by other objects placed on the seat 30.

[0052] Furthermore, determining a triggering strategy for a safety protection device of the vehicle includes:

[0053] S220, when the occupant 38 is in a forward leaning position, the seat belt 33 is triggered to perform end plate pre-tightening operations and buckle pre-tightening operations.

[0054] The buckle is pre-tightened to lock the locking tongue of the seat belt 33 to prevent it from loosening, and the end piece is pre-tightened to tighten the waist belt part of the seat belt 33 to ensure that the waist of the occupant 38 is fixed; at this time, the webbing of the seat belt 33 is not pre-tightened, so that the webbing, especially the shoulder strap, can be flexibly tightened as the position between the head and back of the occupant 38 and the seat 30 is adjusted.

[0055] In this way, by triggering the seat belt 33 to perform the end plate pre-tightening operation and the buckle pre-tightening operation, the safety of the occupant 38 in the forward leaning position is protected.

[0056] Preferably, different safety thresholds can be set according to the driving state information of the vehicle, such as acceleration, angular acceleration, etc., so as to trigger the safety protection device in a timely and effective manner under different driving states.

[0057] Continue to combine Figures 1 to 3 As shown, in some embodiments, determining the triggering strategy of the vehicle's safety protection device also includes:

[0058] S230: When the acceleration of the vehicle is greater than the first safety threshold, the airbag installed in the headrest 30a of the seat 30 is also triggered to perform a detonation operation.

[0059] The acceleration of the vehicle is greater than the first safety threshold, which corresponds to the actual scenario that the vehicle is rear-ended. At this time, the occupant 38 is in a forward leaning position. Due to inertia, the head of the occupant 38 will accelerate backward and violently collide with the seat 30. By triggering the airbag installed in the headrest 30a to perform the detonation operation, the head of the occupant 38 can be protected, and targeted protection of the occupant 38 in the forward leaning position can be achieved.

[0060] Continue to combine Figures 1 to 3 As shown, in some embodiments, determining the triggering strategy of the vehicle's safety protection device also includes:

[0061] S240, when the capacitive sensor pad 31b arranged in the lumbar area does not detect a capacitance value and the acceleration of the vehicle is greater than the first safety threshold, the airbag installed in the seat back 30b of the seat 30 and the airbag installed in the headrest 30a of the seat 30 are also triggered to perform a detonation operation.

[0062] In this way, the head and upper body of the occupant 38 that are not leaning against the headrest 30 a and the seatback 30 b of the seat 30 can be protected at the same time, thereby achieving targeted protection for the occupant 38 in a forward leaning posture.

[0063] Figure 4 The steps of determining that the occupant is in a standard posture and the corresponding safety triggering strategy are shown. Figure 5 The figure shows the state where the occupant is in a standard posture; wherein, Figure 5 The seat 30 is shown in a lying position, but is not limited thereto.

[0064] Combination Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, determining the occupant posture includes:

[0065] S410, when the capacitance sensor pad 31a arranged in the seat area and the capacitance sensor pad 31c arranged in the backrest area detect capacitance values, and the webbing pull-out length detection value matches the standard pull-out length corresponding to the angle detection value, it is determined that the occupant 38' is in the standard posture.

[0066] Furthermore, determining a triggering strategy for a safety protection device of the vehicle includes:

[0067] S420: When the occupant 38' is in the standard posture, the seat belt 33 is triggered to perform a webbing pre-tightening operation.

[0068] When the occupant 38' is in the standard position, various parts of his body press against various areas of the seat 30, and the safety belt 33 is triggered to perform the webbing pre-tightening operation to tighten the webbing, so that the occupant 38' and the seat 30 remain relatively stable, thereby achieving targeted protection for the occupant 38' in the standard position.

[0069] Combination Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, determining the triggering strategy of the vehicle's safety protection device also includes:

[0070] S430: When the seat angle detection value is greater than the angle distinction value and the acceleration of the vehicle is less than the second safety threshold, the knee airbag installed in front of the seat 30 is triggered to perform a detonation operation.

[0071] Taking the case of using an angle distinction value as an example, if the seat angle detection value is greater than the set angle distinction value, it indicates that the seat 30 is in a lying position at this time, and it can be determined that the occupant 38' is in a standard lying position at this time. In the standard lying position state, when the acceleration of the vehicle is less than the second safety threshold, the actual scene is usually a collision, sudden braking, etc. of the vehicle, and the occupant 38' is easy to slide forward. At this time, the knee airbag installed in front of the seat 30 is triggered to perform the detonation operation, which can specifically protect the safety of the occupant 38' in the standard lying position.

[0072] Among them, the knee airbag installed in front of the seat 30, specifically, is installed in the instrument panel to protect the knees of the main driver and the front passenger, and is installed in the backrest of the front seat to protect the knees of the rear passengers.

[0073] Furthermore, in the above embodiments, the capacitive sensor pads arranged in each area are at least respectively located on both sides of each area; determining the triggering strategy of the vehicle's safety protection device also includes: when only the capacitive sensor pad on one side detects a capacitance value and the acceleration of the vehicle is greater than a first safety threshold or less than a second safety threshold, the side airbag installed on the side of the seat is also triggered to perform a detonation operation.

[0074] Specifically, it can be combined Figure 3 and Figure 5 The capacitive sensor pad 31a arranged in the seat area, the capacitive sensor pad 31b arranged in the lumbar area, and the capacitive sensor pad 31c arranged in the backrest area can include two on the left and right respectively, so as to detect whether the left and right sides of various parts of the occupant's body are pressed against the seat 30. When only the capacitive sensor pad on one side detects the capacitance value, it indicates that the occupant is in an oblique position, such as sitting sideways, lying sideways, leaning forward sideways, etc. When the occupant is in an oblique position, if the vehicle is rear-ended or hit, and the speed changes drastically, the occupant will hit the side of the vehicle due to the extreme instability of the body. At this time, the side airbag installed on the side of the seat, such as the side air curtain, is triggered to perform the detonation operation, thereby realizing targeted protection for the occupant in the oblique position.

[0075] In addition, in the above embodiments, determining the triggering strategy of the vehicle's safety protection device also includes: when the acceleration of the vehicle is less than a second safety threshold, triggering the head airbag installed in front of the seat to perform a detonation operation.

[0076] In the event of a sudden deceleration such as a vehicle collision or sudden braking, the head airbags installed in front of the seats, such as airbags installed in the steering wheel and airbags installed on top of the windshield, can be triggered to detonate regardless of the occupant's position to protect the occupant's head.

[0077] In addition to the safety services described in the above embodiments, in some embodiments, the method of providing vehicle services based on occupant posture of the present invention can also provide targeted seat heating services, including: in response to a seat heating signal, triggering a heating sensor pad at a location where a capacitive sensor pad whose capacitance value is detected is located to perform a heating operation; wherein the arrangement positions of the heating sensor pad and the capacitive sensor pad correspond to each other.

[0078] Specifically, it can be combined Figure 3 and Figure 5On the seat 30, the arrangement positions of the heating sensor pad and the capacitive sensor pad correspond to each other, that is, the position area of ​​the capacitive sensor pad 31a arranged in the seat area is arranged with the first group of heating sensor pads, the position area of ​​the capacitive sensor pad 31b arranged in the lumbar area is arranged with the second group of heating sensor pads, and the position area of ​​the capacitive sensor pad 31c arranged in the backrest area is arranged with the third group of heating sensor pads. When the controller receives the seat heating signal, it triggers the heating sensor pad at the position of the capacitive sensor pad where the capacitance value is detected to perform a heating operation to heat the body part of the occupant leaning against the seat 30, which not only saves power consumption, but also matches the occupant's intention and improves the occupant's use experience.

[0079] The embodiment of the present invention also provides a system for providing vehicle services based on passenger posture, which can be used to implement the method for providing vehicle services based on passenger posture described in any of the above embodiments. The features and principles described in any of the above embodiments can be applied to the system for providing vehicle services based on passenger posture.

[0080] Figure 6 The main modules of the system for providing vehicle services based on occupant posture are shown; Figure 6 As shown, the system 500 for providing vehicle services based on passenger posture of the present invention includes:

[0081] The occupant posture determination module 510 is used to determine the occupant posture in response to the capacitance detection value and angle detection value of the seat and the webbing extension length detection value of the seat belt; wherein the capacitance detection value is obtained by detection of the capacitance sensor pads arranged in the backrest area, the waist area and the seat area of ​​the seat;

[0082] The safety strategy determination module 520 is used to determine the triggering strategy of the vehicle's safety protection device according to the occupant's posture; wherein the safety protection device includes a seat belt and an airbag.

[0083] Furthermore, the system 500 for providing vehicle services based on occupant posture may also include modules for implementing other process steps of the above-mentioned method embodiments for providing vehicle services based on occupant posture.

[0084] The system for providing vehicle services based on the occupant's posture of the present invention combines the capacitance detection value and angle detection value of the seat and the detection value of the seat belt's webbing pull-out length to accurately determine the occupant's posture, and then accurately determines the triggering strategy of safety protection devices such as seat belts and airbags based on the occupant's posture, thereby protecting the occupant's safety in a targeted manner and meeting the needs of users. In addition, the system for providing vehicle services based on the occupant's posture of the present invention can also provide targeted seat heating services by triggering the heating sensor pad at the corresponding position through the capacitance sensor pad to perform a heating operation, thereby heating the body part of the occupant that is pressed against the seat, which not only saves power consumption but also matches the occupant's intentions and enhances the occupant's user experience.

[0085] An embodiment of the present invention further provides an electronic device, including a processor and a memory, wherein executable instructions are stored in the memory, and when the executable instructions are executed by the processor, the method for providing vehicle services based on occupant posture described in any of the above embodiments is implemented.

[0086] The electronic device of the present invention can be deployed in a vehicle, for example, integrated into a controller of the vehicle, to realize accurate determination of the occupant's posture by combining the capacitance detection value and angle detection value of the seat and the detection value of the seat belt's webbing pull-out length, and then accurately determine the triggering strategy of safety protection devices such as seat belts and airbags according to the occupant's posture, so as to protect the occupant's safety in a targeted manner and meet the needs of users; in addition, the heating operation can be performed by triggering the heating sensor pad at the corresponding position by the capacitance sensor pad, thereby providing targeted seat heating services and heating the body part of the occupant that is pressed against the seat, which not only saves power consumption but also matches the occupant's intentions and improves the occupant's user experience.
