Description
Airbag disposal method, device and computer-readable storage medium for scrapped vehicles
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on October 27, 2023, with application number 202311411770.0, entitled “A method, device and computer-readable storage medium for processing airbags of scrapped vehicles”, the entire contents of which are incorporated herein by reference. Technical Field
[0003] The present invention relates to the field of intelligent network technology, and in particular to a method and device for processing airbags of scrapped vehicles, and a computer-readable storage medium. Background Art
[0004] Airbags (SRS) are passive safety devices in vehicles designed to reduce the severity of injuries caused by traffic accidents. However, after a certain period of use, vehicles must be scrapped according to regulations. When a vehicle is scrapped, its airbags are not necessarily inoperative. If improperly handled, they can cause false alarms, acting as a "bomb" and directly injuring people.
[0005] To prevent false airbag alarms in scrapped vehicles, the industry is gradually promoting a traditional airbag deployment method: removing the airbag and placing it in a desolate, open area, where it is then deployed using a dedicated deployment tool. This method can deploy airbags in scrapped vehicles, but requires a dedicated deployment tool, which adds a certain amount of cost.
[0006] With the increasing prevalence of remote vehicle control capabilities, a technology for remotely deploying airbags has emerged. This involves sending commands from an external device to a remote server, which then connects to the vehicle's TBOX and pushes the remote command to the vehicle, triggering airbag deployment. This technology addresses the cost of dedicated deployment tools while also ensuring safety. However, remote deployment is affected by the TBOX network environment, resulting in poor real-time performance.
[0007] Summary of the Invention
[0008] The technical problem to be solved by the embodiments of the present invention is to provide a method, device and computer-readable storage medium for handling airbags of scrapped vehicles, so as to improve the safety and convenience of airbag handling.
[0009] In order to solve the above technical problems, the present invention provides a method for treating airbags of scrapped vehicles, comprising the following steps:
[0010] When the preset detonation countdown expires, the onboard host of the scrapped vehicle determines whether the current position of the scrapped vehicle is within the preset detonation area;
[0011] If the current position of the scrapped vehicle is within the preset detonation area, the vehicle-mounted host calls the "detonation command" of the airbag controller to execute the detonation of the airbag.
[0012] Through the above steps, it can be seen that the present invention utilizes the existing on-board host in the scrapped vehicle to execute the function of detonating the airbag at a fixed time and location, which can not only detonate the airbag, but also does not require the development of an additional detonation tool, and basically does not increase the vehicle manufacturing cost of the host manufacturer, thereby greatly avoiding casualties caused by the sudden detonation of the airbag in the scrapped vehicle.
[0013] Preferably, before the detonation countdown starts, the method further includes:
[0014] The vehicle-mounted host imports a configuration file storing the latitude and longitude and detonation radius of multiple preset detonation points; and when the scrapped vehicle drives to any detonation point, in response to a request to set a detonation countdown, calls a clock management module of the central processing unit through a predefined set timed event SOA interface to set the detonation countdown.
[0015] Preferably, the timing duration of the detonation countdown is a relative time.
[0016] Preferably, when the preset detonation countdown expires, the vehicle-mounted host receives a timed event notification and is awakened, and the vehicle-mounted host determines whether the current position of the scrapped vehicle is within the preset detonation area, specifically comprising:
[0017] According to the configuration file, traverse a plurality of preset detonation points, calculate the distance between each detonation point and the current position of the scrapped vehicle, and obtain the shortest distance between the detonation point and the current position of the scrapped vehicle;
[0018] It is determined whether the shortest distance is less than or equal to a preset detonation radius. If so, it is determined that the scrapped vehicle is located within the preset detonation range; otherwise, it is determined that the scrapped vehicle is not within the preset detonation range.
[0019] Preferably, if the current position of the scrapped vehicle is within a preset detonation range, the vehicle-mounted host calls the airbag controller through a predefined airbag detonation SOA interface and sends an airbag detonation command to the airbag controller, and the airbag controller executes the airbag detonation operation according to the airbag detonation command.
[0020] Preferably, after the airbag is detonated, the method further includes: the vehicle-mounted host receives the detonation result and issues a detonation status reminder according to the detonation result.
[0021] Preferably, if the detonation result is a successful detonation, the vehicle-mounted host calls a predefined SOA interface for turning on the hazard indicator light and turns on the hazard indicator light through the central processing unit; if the detonation result is a failed detonation, the vehicle-mounted host calls a predefined SOA interface for turning on the horn and turns on the horn through the central processing unit.
[0022] The present invention also provides an airbag handling device for scrapped vehicles, comprising an on-board host, a central processing unit (CCU), and an airbag controller. The on-board host is configured to determine whether the current position of the scrapped vehicle is within a preset detonation area when a detonation countdown preset by the central processing unit (CCU) expires; and is further configured to call the airbag controller to execute airbag detonation when the current position of the scrapped vehicle is within the preset detonation area.
[0023] The present invention also provides an airbag disposal device for scrapped vehicles, comprising:
[0024] one or more processors;
[0025] Memory;
[0026] One or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the one or more processors, and the one or more applications are configured to execute the airbag handling method for scrapped vehicles.
[0027] The present invention also provides a computer-readable storage medium, which includes a stored computer program; wherein, when the computer program is run, it controls the device where the computer-readable storage medium is located to execute the airbag processing method for scrapped vehicles.
[0028] The present invention has the following beneficial effects: It utilizes the existing onboard host computer in a scrapped vehicle to trigger the airbag deployment at a fixed time and location. Compared to remote airbag deployment, it can deploy the airbag with significantly improved stability and speed. It also eliminates the need for developing a separate deployment tool, substantially minimizing the cost of vehicle manufacturing for the OEM and significantly preventing casualties caused by sudden airbag deployment in scrapped vehicles. Furthermore, the hazard lights or horn can be used to assist in determining whether the airbag has deployed successfully. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.
[0033] As shown in FIG1 , a first embodiment of the present invention provides a method for treating airbags of scrapped vehicles, comprising the following steps:
[0034] When the preset detonation countdown expires, the onboard host of the scrapped vehicle determines whether the current position of the scrapped vehicle is within the preset detonation area;
[0035] If the current position of the scrapped vehicle is within a preset detonation area, the vehicle-mounted host calls the airbag controller to execute detonation of the airbag.
[0036] Through the above steps, it can be seen that the present invention utilizes the existing on-board host in the scrapped vehicle to execute the function of detonating the airbag at a fixed time and location, which can not only detonate the airbag, but also does not require the development of an additional detonation tool, and basically does not increase the vehicle manufacturing cost of the host manufacturer, thereby greatly avoiding casualties caused by the sudden detonation of the airbag in the scrapped vehicle.
[0037] Specifically, as shown in Figure 2 , the airbag disposal method for scrapped vehicles according to an embodiment of the present invention involves the vehicle's host computer, central processing unit (CCU), airbag controller, exterior lighting system, horn system, and vehicle network. Also, as shown in Figure 3 , the airbag disposal method for scrapped vehicles according to an embodiment of the present invention requires certain pre-configuration steps and settings, including the detonation position and detonation countdown.
[0038] (1) Detonation location setting
[0039] The detonation specialist enters multiple detonation points and radiuses through the scrapped vehicle's onboard host interface. A relatively large detonation site may contain multiple detonation points. Entering multiple detonation points allows for simultaneous detonation or when several detonation points are occupied. Due to the controllability of the detonation site, the present invention uses the detonation point location plus detonation radius to subsequently determine whether the scrapped vehicle is within the designated detonation area.
[0040] To determine the detonation point locations, use a GPS device (such as a mobile phone) to measure the longitude and latitude of each detonation point. Each detonation point is measured 10 times and averaged to obtain the processed longitude and latitude coordinates. The longitude and latitude of the detonation points and the preset detonation radius are then stored in a configuration file (in JSON format, for example). The vehicle host imports this configuration file and saves it. When the application runs, the configuration file is read into memory, using a structure array to store the longitude and latitude of all detonation points and an integer to store the detonation radius.
[0041] (2) Detonation countdown setting
[0042] The detonation specialist drives the scrapped vehicle to any pre-entered detonation point location and sets the detonation countdown time (for example, setting the time to 10 minutes) through the vehicle host interface.
[0043] The central processing unit (CCU)'s time management module provides time-related service-oriented architecture (SOA) services using the SomeIP protocol. The vehicle host uses the SOA interface shown in Table 1-1 over the vehicle Ethernet to call the timed event service interface of the CCU's clock management module to set the detonation countdown duration.
[0044] Table 1-1 Setting the scheduled event service interface
[0045] After the time management module receives the request to set the detonation countdown duration, it will trigger the setting of the detonation countdown duration. There are two main ways to set the detonation countdown duration: absolute time and relative time. The differences between the two are as follows:
[0046] Absolute time: This can be understood as clock time, such as 08:10:10. This time can jump depending on the clock synchronization source and is unstable. For example, if the timer is set from 8:00 to 9:00, which is exactly one hour, if the clock is set forward half an hour during the timer, the timer will reach 9:00 in half an hour, and the timer duration will be inaccurate.
[0047] Relative time: This is a stable time that does not change with the speed of the clock. For example, if the timer is set from 8:00 to 9:00, it is exactly one hour. If the clock is set forward by half an hour during the timer, it will not affect the final timer duration.
[0048] The embodiment of the present invention uses a relative time setting method to implement detonation countdown timing, which has the following advantages:
[0049] Compared with absolute time, relative time only requires inputting a duration data, which is simpler to set up and more user-friendly.
[0050] As a terminal, a vehicle's time synchronization is affected by various factors, including GPS and its own RTC clock. Absolute time can fluctuate and cause timing inaccuracies. If time fluctuations cause scheduled events to arrive prematurely, this can significantly increase the risk to the detonator. Setting a relative duration ensures time stability and provides adequate safety for the detonator.
[0051] After completing the above settings, the vehicle remains awake until the detonation specialist leaves the scrapped vehicle. When the detonation specialist leaves the scrapped vehicle, the detonation countdown begins. When the detonation countdown expires, the vehicle host receives a timed event notification. See Table 2-1 for the parameters for subscribing to timed event notifications for the vehicle host.
[0052] Table 2-1 Vehicle host subscription timed events
[0053] When the detonation countdown expires, the central processing unit (CCU) wakes up the vehicle network and powers up the onboard host. After powering up, the host receives a timed event notification from the time management module indicating the detonation countdown has expired (the host has subscribed to timed events as shown in Table 2-1).
[0054] Next, the vehicle host will determine whether the current location of the scrapped vehicle is within the preset detonation area. The specific determination method is:
[0055] Traversing a plurality of pre-entered detonation points, calculating the distance between each detonation point and the current position of the scrapped vehicle, and obtaining the shortest distance between the detonation point and the current position of the scrapped vehicle, which is the detonation point closest to the scrapped vehicle;
[0056] It is determined whether the shortest distance is less than or equal to a preset detonation radius. If so, it is determined that the scrapped vehicle is located within the preset detonation range; otherwise, it is determined that the scrapped vehicle is not within the preset detonation range.
[0057] The above method of determining whether the current position of the scrapped vehicle is within the preset detonation area is simple and easy to use, and has a fast determination speed, avoiding the complexity of using electronic fences provided by maps, and is very suitable for such a controllable environment.
[0058] If the current position of the scrapped vehicle is within the preset detonation range, the vehicle host calls the airbag controller through SOA and sends an airbag detonation command to it; the airbag controller receives the airbag detonation command and executes the airbag detonation operation.
[0059] The vehicle host uses the SOA interface in Table 3-1 through the vehicle Ethernet to call the airbag deployment service interface of the airbag controller and send the airbag deployment command.
[0060] Table 3-1 Airbag deployment service interface
[0061] After deploying the airbag, the vehicle host receives a successful or failed deployment result and then issues a status notification based on the deployment result. Specifically, the vehicle host calls the SOA interfaces listed in Tables 4-1 and 4-2 to activate the hazard lights and horn via the central processing unit.
[0062] Table 4-1 Hazard indicator light on
[0063] Table 4-2 Horn honking start
[0064] At this time, observe the hazard lights and horn of the scrapped vehicle. If the hazard lights are on, it means that the airbag has been successfully detonated; if the horn is honking, it means that the airbag has not been successfully detonated.
[0065] If the current location of the scrapped vehicle is not within the preset detonation range, the detonation will be ignored. If you need to continue the detonation, you need to drive the scrapped vehicle to another pre-set detonation point, set the detonation countdown, and continue the subsequent process.
[0066] The embodiments of the present invention do not require a dedicated detonation device. Instead, the scrapped vehicle itself can be equipped with an airbag detonation function. Using the vehicle's onboard host, the airbag is deployed at a fixed time and location. Compared to remote airbag deployment, this is not only safer but also significantly more stable and rapid. Furthermore, hazard lights or horn honking can be used to assist in determining whether the airbag has deployed successfully.
[0067] Corresponding to the airbag handling method for scrapped vehicles described in the first embodiment of the present invention, the second embodiment of the present invention further provides an airbag handling device for scrapped vehicles, comprising an on-board host, a central processing unit (CCU), and an airbag controller. The on-board host is configured to determine whether the current position of the scrapped vehicle is within a preset detonation area when a detonation countdown preset by the central processing unit (CCU) expires; and is further configured to invoke the airbag controller to execute airbag deployment when the current position of the scrapped vehicle is within the preset detonation area.

[0069] one or more processors;
[0070] Memory;
[0071] One or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the one or more processors, and the one or more applications are configured to execute the airbag handling method for scrapped vehicles according to embodiment 1 of the present invention.

The processor is the control center of the device, and various parts of the device are connected using various interfaces and lines.
[0075] The memory mainly includes a program storage area and a data storage area, wherein the program storage area can store an operating system, at least one application required for a function, etc., and the data storage area can store related data, etc. In addition, the memory can be a high-speed random access memory, or a non-volatile memory, such as a plug-in hard disk, a smart media card (SMC), a secure digital (SD) card, and a flash card, etc., or the memory can also be other volatile solid-state storage devices.
[0076] It should be noted that the above-mentioned device may include but is not limited to a processor and a memory, which can be understood by those skilled in the art.
[0077] For the working principle and process of the above embodiment, please refer to the description of the above embodiment of the present invention, which will not be repeated here.
[0078] As can be seen from the above description, compared with the prior art, the present invention offers the following advantages: It utilizes the existing onboard host computer in a scrapped vehicle to execute the timed and targeted airbag deployment function. Compared to remote airbag deployment, the present invention can deploy the airbag with significantly improved stability and speed.
