[0051] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application, and are not used to limit the present application.

[0052] In order to better understand the technical solutions of the present application, the specific embodiments will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] The main solution of the embodiment of the present application is: obtaining the download state, verification state, installation state, flag bit information and real-time state information of the vehicle during over-the-air download upgrade; determining the flag bit state of the flag bit information based on at least one of the download state, the verification state and the installation state; uploading the flag bit state and the real-time state information to the over-the-air download cloud platform, so that the over-the-air download cloud platform performs vehicle breakdown fault early warning according to the flag bit state and the real-time state information.

[0054] With the rapid development of new energy vehicle technology, vehicle over-the-air (OTA) technology has become an important means to improve vehicle performance, repair system vulnerabilities, and update vehicle software. OTA technology enables remote management of vehicle software through mobile communication interfaces, greatly improving the convenience and efficiency of vehicle software updates. However, despite the important role of OTA technology in improving user experience and vehicle safety, OTA upgrade failures leading to vehicle breakdowns cannot be ignored in actual applications. Currently, although the probability of new energy vehicles breaking down due to OTA upgrade failures is low, once it happens, it will greatly inconvenience the daily travel of the vehicle owner and seriously affect the reputation of the vehicle brand. Currently, the market mainly relies on the active feedback of the vehicle owner and the passive response of the after-sales service system for vehicle breakdowns caused by OTA upgrade failures. However, this method has obvious hysteresis and cannot effectively prevent vehicle breakdowns. In addition, since there are various reasons for vehicle breakdowns, it is difficult to accurately determine whether it is caused by OTA upgrade failure based on the feedback of the vehicle owner, which also brings great difficulties to the work of the after-sales service system. Therefore, how to accurately identify scenarios where OTA upgrade failures may lead to vehicle breakdowns and simultaneously perform vehicle breakdown fault warning has become a problem that needs to be solved.

[0055] The present application distinguishes various situations that may lead to vehicle breakdowns during vehicle over-the-air upgrade by using a flag, and accordingly performs vehicle breakdown fault warning, solving the problem of inaccurate vehicle breakdown fault warning during over-the-air upgrade, and improving the accuracy of vehicle breakdown fault warning during over-the-air upgrade.

[0056] It should be noted that the execution subject of the present embodiment can be a vehicle breakdown fault warning system, or a computing service device with data processing, network communication, and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above-mentioned vehicle breakdown fault warning function, etc., and the present embodiment is not specifically limited thereto. The present embodiment and the following embodiments will be described below with the vehicle breakdown fault warning system as an example.

[0057] Based on this, the present embodiment provides a vehicle breakdown fault warning method, which refers to Figure 1 , Figure 1 The present application is applied to a vehicle breakdown fault warning method for the vehicle end.

[0058] In the present embodiment, the vehicle breakdown fault warning method comprises steps S10-S30:

[0059] Step S10: Obtain the download state, the verification state, the installation state, the flag bit information and the real-time state information applied by the vehicle during the over-the-air upgrade.

[0060] It should be noted that in this step, the system first monitors and records the state information of the vehicle during the over-the-air (OTA) upgrade through the vehicle's on-board OTA component. These state information includes but is not limited to the download state (such as downloading, download complete, download failure, etc.), the verification state (such as normal verification, abnormal verification, etc.), the installation state (such as installing, installation success, installation failure, etc.), and the flag bit information. At the same time, the system also collects the real-time state information of the key systems of the vehicle (such as the engine, the battery, etc.). Specifically, assuming that a car is undergoing an OTA upgrade, the system will continuously detect and record the download progress (download state) during the upgrade process through the on-board OTA component, perform file verification (verification state) after the download is complete, and perform installation (installation state) after the verification is correct. At the same time, the system also collects real-time data of the vehicle's engine, battery and other key systems, such as engine operating state, battery power, etc. (real-time state information).

[0061] In addition, it should be noted that the download state refers to the progress and result of downloading the upgrade file from the server to the vehicle end during the OTA upgrade process. The verification state refers to the state of checking the integrity and correctness of the file after the download is complete. The installation state refers to the installation progress and result of the file in the vehicle ECU (Electronic Control Unit) after the verification is correct. The flag bit information refers to the verification parameters pre-set in the system during the vehicle OTA component upgrade process, which is used to accurately distinguish the upgrade failure types that may cause the vehicle to break down.

[0062] Step S20: Determine the flag bit state of the flag bit information based on at least one of the download state, the verification state and the installation state.

[0063] It should be noted that the flag bit state refers to a specific state determined according to the download, verification and installation states, which is used to identify specific abnormalities occurring during the OTA upgrade process. In addition, it should be noted that specifically, after obtaining the above state information, the system will determine and set the state of the flag bit according to the states of download, verification and installation, combined with the pre-set judgment rules. These rules include but are not limited to: setting the first flag bit when the download fails or succeeds, setting the second flag bit when the verification fails or succeeds, setting the third flag bit when the installation process is normal or abnormal (such as power failure), etc.

[0064] Step S30: uploading the flag bit state and the real-time state information to an over-the-air (OTA) cloud platform, so that the OTA cloud platform performs fault early warning of vehicle breakdown according to the flag bit state and the real-time state information.

[0065] It should be noted that the OTA cloud platform is a core platform responsible for vehicle OTA upgrade management and control, which can receive and process information uploaded by the system during the vehicle OTA component upgrade process, and comprehensively analyze and trigger corresponding early warning and rescue mechanisms. Specifically, after the system determines the flag bit state preset in the vehicle OTA component upgrade process, the system uploads the flag bit state and the real-time state information of the vehicle to the OTA cloud platform. It can be understood that the OTA cloud platform will comprehensively analyze the information in combination with the specific model, configuration, etc. of the vehicle to determine whether the vehicle has a breakdown risk caused by OTA upgrade failure. If the result is that there is a risk, the OTA cloud platform will immediately trigger the early warning mechanism to send early warning information to the after-sales service system, so as to timely contact the vehicle owner for confirmation and rescue.

[0066] In this embodiment, the download state, the verification state, the installation state, the flag bit information and the real-time state information of the vehicle during over-the-air upgrade are obtained; the flag bit state of the flag bit information is determined based on at least one of the download state, the verification state and the installation state; the flag bit state and the real-time state information are uploaded to an over-the-air (OTA) cloud platform, so that the OTA cloud platform performs fault early warning of vehicle breakdown according to the flag bit state and the real-time state information. As can be seen from the above, the present application distinguishes various situations that may cause vehicle breakdown during vehicle over-the-air upgrade by flag bits, and accordingly performs vehicle breakdown fault early warning, thereby solving the problem that vehicle breakdown fault early warning cannot be accurately performed during vehicle over-the-air upgrade, and improving the accuracy of vehicle breakdown fault early warning during vehicle over-the-air upgrade.

[0067] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as the above embodiment one can be referred to the above introduction, and will not be described in detail. On this basis, please refer to Figure 2 , Figure 2 The flowchart of the second embodiment of the vehicle breakdown fault early warning method applied to the vehicle end of the present application is shown in FIG. 2. The step S20 further includes:

[0068] Step S201: obtaining the first flag bit state of the first flag bit according to the download state.

[0069] It should be noted that specifically, in the download stage of OTA upgrade, the system detects the download state, and determines whether the flag bit state of the first flag is in the set state or the reset state according to the different download states.

[0070] It can be understood that the flag bit state of the first flag refers to a specific flag bit state for marking the download state, and the setting and resetting of the state respectively represent “incomplete” and “complete”.

[0071] In an implementable embodiment, the step S201 specifically comprises:

[0072] Step A10: When the download state is the incomplete state, determining that the first flag bit state is the set state.

[0073] It should be noted that, as Figure 3 shown, in this step, when the OTA component performs the upgrade, the file to be upgraded will be downloaded first. If an exception occurs during the downloading process, for example, network interruption or server failure, resulting in that the file fails to be successfully downloaded or is not completely downloaded, at this time, the OTX (Open Test Sequence EXchange Format) parser will set the first flag bit to the set (i.e., the download is not completed) state. For example, when the vehicle is in the OTA upgrade process, if the download speed suddenly decreases and stops after a period of time, the OTX parser will determine that the download is abnormal and set the first flag bit to the set state.

[0074] Step S202: obtaining the second flag bit state of the second flag bit according to the download state and the verification state.

[0075] It should be noted that, specifically, after the file is downloaded, the system will detect the verification state, and according to the different verification states, determine whether the flag bit state of the second flag is in the set state or the reset state.

[0076] In an implementable embodiment, the step S202 specifically comprises:

[0077] Step B10: When the download state is the complete state and the verification state is the abnormal state, determining that the second flag bit state is the set state.

[0078] It should be noted that, as Figure 3 shown, in this step, after the file is downloaded, the OTX parser will perform file verification. If it is found that the file is damaged or the content does not match during the verification process, that is, the file has been completely downloaded but the verification fails, at this time, the OTX parser will set the second flag bit to the set (i.e., the verification is abnormal) state. It can be understood that the role of this step is to ensure the integrity and correctness of the upgrade file, and prevent the upgrade from failing due to file damage.

[0079] Step S203: obtaining the third flag bit state of the third flag bit according to the download state, the verification state and the installation state.

[0080] It should be noted that in this step, when the file verification is passed, the OTA upgrade enters the installation stage, and the system determines whether the flag bit state of the third flag is in the set state or the reset state according to different installation states.

[0081] In a possible implementation, the step S203 specifically includes:

[0082] Step C10: When the download state is the complete state, the verification state is the normal state, and the installation state is the failure state, it is determined that the third flag bit state is in the set state.

[0083] It should be noted that specifically, when the file verification is passed, the OTA upgrade enters the installation stage, and if the installation process is interrupted at this time, for example, the vehicle is suddenly powered off or the user manually interrupts the upgrade, the OTX parser sets the third flag bit to the set (i.e., installation failure) state. For example, after the file verification is passed, if the vehicle is suddenly turned off due to insufficient power or other reasons, resulting in interruption of the OTA upgrade installation process, the OTX parser sets the third flag bit to the set state.

[0084] Step S204: Taking the first standard state, the second flag bit state and the third flag bit state as the flag bit state.

[0085] It should be noted that, as shown in Figure 3 In this embodiment, the OTX parser integrates the states of the above three flag bits to form a complete flag bit state, and sends the flag bit state to the UCM (Update and Configuration Management) module for further processing and reporting to the OTA cloud platform. The role of this step is to integrate various state information in the upgrade process, and to provide data support for subsequent early warning and rescue work. For example, after the OTA upgrade is completed, the OTX parser integrates the states of the first flag bit, the second flag bit and the third flag bit, and reports them to the OTA cloud platform through the UCM module as the basis for evaluating the vehicle state and triggering the early warning.

[0086] In this embodiment, the states of different flag bits are determined by the download state, the verification state and the installation state, which can effectively monitor and track the download, verification and installation process of the file in the OTA upgrade process, accurately distinguish the reasons that may cause the OTA upgrade failure under different conditions, and improve the accuracy of the anchor fault early warning in the vehicle over-the-air upgrade process.

[0087] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as the above-mentioned embodiments one and two can be referred to the above description, and the subsequent will not be described in detail. On this basis, please refer to Figure 4 , Figure 4 The flowchart of the third embodiment of the vehicle stranded fault early warning method applied to the over-the-air download cloud platform of the present application further comprises the following steps after step S30:

[0088] Step S40: receiving the flag bit state and real-time state information of the vehicle sent by the vehicle end.

[0089] It should be noted that in the OTA cloud platform, there is a special server for receiving data from the vehicle end. These servers can listen to and receive the flag bit state information and real-time state information sent by the vehicle in real time. Once the data is received, the server will immediately process and store it. In addition, it should be noted that the real-time state information refers to the current engine working state, battery power and other real-time data of the vehicle.

[0090] Step S50: obtaining the engine state and battery power of the vehicle according to the real-time state information.

[0091] It should be noted that after receiving the real-time state information of the vehicle end, the OTA cloud platform will analyze and process it to obtain the engine state and battery power, which provides data support for the subsequent OTA cloud platform to analyze the reasons for OTA upgrade failure and vehicle stranded.

[0092] Step S60: performing vehicle stranded fault early warning according to the flag bit state, the engine state and the battery power.

[0093] It should be noted that after comprehensively analyzing the flag bit state, engine state and battery power and other information sent by the vehicle end, the OTA cloud platform will perform vehicle stranded fault early warning. Specifically, if the flag bit state sent by the vehicle end shows that there is a download exception, file damage or installation exception, etc., at the same time, the running state of the engine is in a stop state and the battery power is not empty, then the cloud platform will judge that the vehicle has a stranded risk, and immediately trigger the fault early warning mechanism.

[0094] In addition, it should be noted that the fault early warning mechanism includes but is not limited to: pushing the early warning information to the after-sales service system, so that the after-sales personnel can contact the vehicle owner in time to confirm the vehicle state and provide rescue service; at the same time, a short message or an APP push message can also be sent to the vehicle owner to remind the vehicle owner to pay attention to the vehicle safety and contact the maintenance center as soon as possible.

[0095] In one possible implementation, the step S60 specifically comprises:

[0096] Step S601: When any one of the flag bit states is in the set state, the engine state is in the stop state, and the battery power is not empty, it is determined that the over-the-air upgrade of the vehicle fails, and the fault information of the vehicle stranded is obtained.

[0097] It should be noted that the fault information refers to the information of the flag bit state, the engine state and the battery power of the vehicle when the vehicle upgrade fails and the vehicle is stranded. Specifically, in this step, the system will judge according to the state of each flag bit set in the OTA component. These flag bits respectively represent different OTA upgrade failure conditions, such as file download exception, file damage, installation exception, etc. When any one of the flag bits is in the set state, it indicates that an abnormal situation occurs in the OTA upgrade process. At the same time, the system will also judge in combination with the real-time state of the engine. If the engine state is in the stop state, it indicates that the current vehicle has entered the stranded state or will enter the stranded state. In addition, the system will consider the factor of the battery power. If the battery power is not empty, the stranded situation caused by the battery power depletion during the OTA upgrade failure can be excluded.

[0098] Step S602: According to the fault information of the vehicle stranded, the fault warning of the vehicle stranded is performed.

[0099] It should be noted that, as shown in Figure 5 , the vehicle end and the OTA cloud platform are connected with each other, and the OTA is connected with the after-sales service platform. Specifically, after the after-sales service platform receives the vehicle stranded fault information sent by the OTA cloud platform, the after-sales service platform will automatically query the VIN (Vehicle Identification Number) information of the vehicle, and send the vehicle stranded fault information to the nearest store, so that the maintenance personnel go to the scene for rescue.

[0100] In this embodiment, by receiving the flag bit state, the engine state and the battery power when the OTA upgrade fails, the scene that the OTA upgrade failure may cause the vehicle to be stranded can be accurately identified, and the fault warning is performed at the first time, thereby effectively avoiding the inconvenience and loss brought to the vehicle owner by the vehicle stranded, and improving the user experience.

[0101] The application also provides a vehicle stranded fault warning device applied to a vehicle end, for supporting the vehicle stranded fault warning method provided by any one of the above embodiments or combinations thereof, with reference to Figure 6 , Figure 6 The module structure diagram of the vehicle stranded fault warning device 100 applied to the vehicle end of an embodiment of the application is shown in the figure. The device 100 comprises:

[0102] The information acquisition module 110 is configured to acquire download status, check status, installation status, flag bit information and real-time status information of the vehicle during over-the-air upgrade.

[0104] The information sending module 130 is configured to upload the flag bit state and the real-time status information to an over-the-air cloud platform, so that the over-the-air cloud platform performs fault early warning of the vehicle based on the flag bit state and the real-time status information.

[0105] The application also provides a fault early warning device for vehicle breakdown applied to an over-the-air cloud platform.
