[0028] The following flowchart illustrates the operations performed according to the manufacturing process of the fairing part. It should be understood that the preceding or subsequent operations are not necessarily performed in exactly the same order, depending on the actual situation. Additional operations may also be added to these processes, or one or more steps may be removed.Although the interior parts disclosed in the embodiments of the present application are applicable to the surfaces of the interior parts of automobiles, namely interior panels, which may be, for example, a door side panel, a roof panel, a dashboard or instrument panel, a center console, and other interior parts of automobiles, and the shapes of the interior parts are of various forms, they are not limited thereto. For example, they may also be applicable to other applications of vehicles, such as railway trains, ships, and aircraft, as long as the vehicles can use the interior panels disclosed in the embodiments of the present application, and they are not limited thereto.As long as the interior part can be used to improve the safety performance of a vehicle equipped with an airbag, in accordance with the present application, it is one of the interior parts covered by the present application.

[0029] With reference to Fig. 1. An interior system 1000 of a vehicle comprises, for example, interior parts 10 such as an instrument panel 1001, a door panel 1002, a center console 1003, etc. Currently, the instrument panel 1001 and the door panel 1002 are generally separate structures that can be clearly distinguished visually. However, it is not impossible that the instrument panel 1001 and the door panel 1002 have a similar structure and form a solution for an interior system 1000 in which the instrument panel 1001 and the door panel 1002 create an integrated visual impression.

[0030] Typically, an airbag is located below the instrument panel 1001 in the interior system, but this is not a limitation. For example, the door trim 1002 and the headliner can also be equipped with airbags; that is, side airbags and head airbags can be provided to further increase vehicle safety. In the following embodiments, the interior part 10 is presented as an example of the interior part of the instrument panel 1001, since the instrument panel 1001 is a part located directly at the front and represents the most typical application scenario for an airbag.

[0031] As in Fig. As shown in Figure 1, in some embodiments the interior part 10 comprises a panel 1 and a sensor element 2.

[0032] Panel 1 has a front 11 and a back opposite the front 11; that is, the side facing the user is the front 11, and the side not visible to the user is the back, which is therefore not shown in the drawings. Panel 1 has a first area 110, which serves for the corresponding arrangement of an airbag cover 120 on the back. It is understood that the airbag cover 120 can be opened under the effect of the airbag's inflation pressure, generally along the weakening line 130 when the airbag is deployed, but is not limited to this. It is understood that the airbag cover 120 and the weakening line 130 are generally not visible and are shown in the drawing only for the purpose of a clear schematic illustration of the technical solution.

[0033] The material of Panel 1 can be plastic, such as common polypropylene, PP plastic, e.g., acrylonitrile butadiene styrene copolymer (ABS plastic), PC / ABS alloy, ABS engineering plastic, etc. Another example is a composite material, where, for instance, the matrix of the composite material consists of plastic and the reinforcement material consists of fiber materials such as natural fibers and / or synthetic fibers, forming the fiber-reinforced plastic composite. Examples include natural fiber-reinforced PP plastic (NFPP), glass fiber-reinforced PP plastic (GFPP), a composite material consisting of 40% natural fibers, 50% polypropylene, and 10% recycled carbon fibers (rCF NFPP), or, for example, a composite material called NAFILean®, which combines natural linen fibers with PP.Natural fibers can include wood fibers, jute, hemp, kenaf, flax, ramie, rattan, soy, okra (coffee toad), banana plants, bamboo, coconut, coconut fibers, cotton fabrics, curaua fibers (pineapple leaf fibers), abaca (Manila hemp), pine, pineapple, sugar palm (Corypha farinifera) leaves, and / or sisal. Synthetic fibers can include, for example, carbon fibers, polyester fibers, acrylic fibers, aramid fibers, Twaron fibers, Kevlar fibers, Technora fibers, Vinalon fibers, Zylon fibers, and / or polypropylene fibers, etc.

[0034] Regarding the sensor element 2, its sensor area is the front 11 of the panel to detect whether a dangerous object 3 is placed on the front 11 of the panel.

[0035] The dangerous object 3 mentioned here is an object that falls out together with the airbag when the airbag cover 120 is opened, thereby causing a safety hazard, for example decorations (e.g. character figures) etc. placed there by the user.

[0036] The special shape of the sensor element 2 can be a sensor 21, which is easy to install, has a compact structure, and is cost-effective. The sensor 21 is generally located on the back of the panel.

[0037] Specifically, the sensor can, for example, include a force sensor, which could be a pressure sensor. The pressure sensor detects the pressure exerted on the front surface 11 of the panel 1. If the pressure is higher than the pressure threshold, it can be determined that a dangerous object 3 is placed on the front surface 11 of the panel, and an alarm signal is subsequently issued.

[0038] For example, the sensor may also include a light sensor, which could be an infrared sensor. If an object covering the sensor range of the infrared sensor is placed on the first area 110 of the panel 1, it can be determined that a dangerous object 3 is placed on the front 11 of the panel, and an alarm signal is subsequently issued.

[0039] It is understood that the sensor element 2 can also be a camera 22, which is, for example, located on the top of the vehicle. A recording area 220 of the camera on the panel 1 encompasses the first area 110, so that the image captured by the camera 22 can be automatically determined by a visual algorithm whether a dangerous object 3 is located in the first area 110. If it is determined that a dangerous object 3 is located there, an alarm signal is subsequently issued.

[0040] It is understood that the shape of sensor element 2 is not limited to the force sensor, light sensor, and camera introduced above, but can also take other forms. All components capable of capturing a sensor signal and outputting it to a control unit for reception and evaluation belong to sensor element 2.

[0041] With reference to Fig. 2. Following the contents described above, the present application also provides an alarm method in which the interior part 10 introduced in the embodiment above is used, the alarm method comprising: S100. Receiving a sensor signal from the sensor element 2, which detects the front 11 of the panel; S200. Determine if a dangerous object 3 is placed on the front 11 of the panel; S300. Emits an alarm signal when a dangerous object 3 is detected placed; S400. Maintain a normal state when it is determined that no dangerous object 3 is placed.

[0042] In some embodiments, the alarm signal in the S300 includes a sound, a light, an image, or text. For example, the alarm sound can be emitted via a speaker inside the vehicle. Similarly, a visual alarm can be triggered by a change in the brightness or color of the interior lighting, such as sudden changes in brightness, continuous flashing, or the illumination of a red flashing light. An image or text signal can also be output via the vehicle's human-machine interface, for example, via the vehicle's display with a warning message such as "Please do not place any objects in the airbag area" or similar.

[0043] In some embodiments, the output of the alarm signal in S300 can be combined with the probability of airbag deployment (or the probability of collision) to implement a staged alarm. That is, if it is detected that a dangerous object 3 is present, the output of the alarm signal includes the following steps: If the probability of the airbag cover opening is a first probability, then the magnitude of the alarm signal issued is a first magnitude; If the probability of the airbag cover opening is a second probability, then the magnitude of the alarm signal issued is a second magnitude; where the second probability is greater than the first probability, and the second extent is greater than the first extent.

[0044] For example, it can be stipulated that if the vehicle is traveling at high speed, the probability of the airbag cover deploying is set as a second probability for high-speed travel and a first probability for low-speed travel, compared to low-speed travel. If a dangerous object is detected at the front 11 of the panel during high-speed travel, the intensity of the alarm sounded at that moment is greater than the intensity of the alarm at low speed. For example, the volume and frequency of the alarm tone at high speed are more penetrating compared to the alarm tone at low speed and are more likely to attract the user's attention.For example, the flashing frequency of the visual alarm (using light) can be higher at high speed, the font size of texts or patterns can be larger, and so on.

[0045] With reference to Fig. 3 The present application further provides an alarm system 100 comprising the interior part 10 described in the preceding embodiments and a control unit 40, wherein the control unit comprises a memory 41 and a processor 42, wherein the memory 41 can store the instructions executable by the processor, and the processor 42 can execute the instructions to implement the steps of the alarm procedure described in the preceding embodiments performed by a computer.

[0046] It is important to note that the aforementioned memory and processor are not limited to a specific single memory or processor. For example, in some cases, the memory and processor can both have a distributed structure. For instance, they can comprise memory and a processor located at the vehicle end and the cloud backend, respectively, with the alarm procedure described above being implemented jointly by both the vehicle end and the cloud backend. Furthermore, in embodiments using a distributed structure, the specific execution unit of each step can be adapted according to the actual conditions, and the specific schemes for implementing each step in a particular unit should not limit the scope of protection of this application.

[0047] According to another aspect of the present application, the present application also provides a computer-readable medium.

[0051] In summary, the advantageous effects of using the aforementioned embodiments can be described, among other things, as follows: by arranging a sensor on the interior panel, the sensor can detect whether an object is located in the area of ​​the interior panel corresponding to the airbag cover. This allows further warning messages to be issued to the user, thereby increasing vehicle safety.
