Description

Technical Field

[0001] The invention relates to the technical field of automobile fault data evaluation systems, and in particular to an automobile fault data evaluation system. Background Art

[0002] In the current automotive industry, with the rapid development of electronic control technology, the electronic control systems inside vehicles have become increasingly complex and highly integrated. These systems include but are not limited to engine management systems, transmission systems, braking systems, body control systems, and advanced driver assistance systems. They are interconnected through a large number of sensors, actuators, and electronic control units (ECUs) to jointly ensure the safety, performance, and economy of the vehicle. However, this highly integrated electronic control system also brings challenges to fault diagnosis. When a vehicle fails, the ECU will record the corresponding fault code, which is an important basis for diagnosing vehicle problems. However, traditional fault code reading tools can only provide the fault code itself and its simple description information. In addition, the existing fault code evaluation system has the following deficiencies: Insufficient data processing capabilities: Faced with massive amounts of fault code data, traditional evaluation systems are often difficult to process efficiently and accurately, resulting in low diagnostic efficiency. Low evaluation accuracy: Due to the lack of in-depth mining and analysis of fault code data, existing evaluation systems often find it difficult to accurately determine the root cause and severity of the fault, and are prone to misdiagnosis or missed diagnosis. Poor ability to identify unconventional faults: With the continuous development of automotive technology, new fault modes and problems continue to emerge. However, existing evaluation systems often lack the ability to effectively identify and evaluate new faults, making it difficult to meet the needs of automobile maintenance. The information island phenomenon is serious: the fault code data format and encoding method between different brands and models are different, resulting in the inability to effectively share and communicate information, making it difficult to ensure the safety of automobile drivers. Therefore, an automobile fault data evaluation system is proposed to solve the above problems. Summary of the invention

[0003] In view of this, an object of the present invention is to provide an automobile fault data evaluation system to at least solve the above problems.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A vehicle fault data evaluation system, the system comprising a remote terminal and a vehicle-mounted system, the remote terminal being in communication connection with the vehicle-mounted system, the remote terminal being provided with a fault acquisition module, an analysis module, an evaluation module and an early warning module, the system being used to execute a vehicle fault data evaluation method, the method comprising the following steps:

[0006] S1. Collect fault data on the vehicle system through a fault collection module;

[0007] S2, the analysis module analyzes the collected fault data and obtains the analysis results;

[0008] S3, the evaluation module evaluates the analysis result to obtain an evaluation result;

[0009] S4, the warning module sends safety warning information to the vehicle system based on the evaluation results;

[0010] S5. When the vehicle-mounted system receives the safety warning information, it prompts the safety warning information.

[0011] Furthermore, in step S1, the fault data includes the vehicle fault code, the vehicle model and the model of the component to which the fault code belongs.

[0012] Furthermore, in step S2, the following sub-steps are also included:

[0013] S21, the analysis module classifies the collected vehicle fault codes into active fault code type and inactive fault code type data;

[0014] S22, the analysis module matches the activity type fault code with the dangerous consequence corresponding to the activity type fault code stored in the remote terminal, and if they match, obtains the dangerous consequence analysis result of the stored activity type fault code;

[0015] S23. The analysis module matches the inactive type fault code with the warning consequence corresponding to the inactive type fault code stored in the remote terminal. If the match is consistent, the analysis result of the stored inactive type fault code warning consequence is obtained.

[0016] Furthermore, in step S3, the following sub-steps are included:

[0017] S31, the evaluation module sets an activity score threshold and an inactivity score threshold;

[0018] S32, the evaluation module obtains the corresponding activity score in the dangerous consequence analysis result of the active type fault code, and obtains the corresponding inactive score in the early warning consequence analysis result of the inactive type fault code;

[0019] S33, the assessment module compares the obtained activity score with the set activity score threshold. If the activity score is greater than the set activity score threshold, a high-risk activity assessment result is obtained; if the activity score is less than the set activity score threshold, a low-risk activity assessment result is obtained;

[0020] S34. The evaluation module compares the obtained inactivity score with the set inactivity score threshold. If the inactivity score is greater than the set inactivity score threshold, an inactivity high warning evaluation result is obtained; if the inactivity score is less than the set inactivity score threshold, an inactivity low warning evaluation result is obtained.

[0021] Furthermore, in step S4, the warning module sends safety warning information to the vehicle system according to the evaluation result:

[0022] The early warning module matches the corresponding high-risk safety warning information, low-risk safety warning information, high-warning safety warning information, and low-warning safety warning information stored in the remote control terminal based on the received active high-risk assessment results, active low-risk assessment results, inactive high-warning assessment results, and inactive low-warning assessment results.

[0023] Further, in step S5, when the vehicle-mounted system receives the safety warning information, the prompt of the safety warning information is specifically:

[0024] When the vehicle-mounted system receives high-risk safety warning information, low-risk safety warning information, high-warning safety warning information, and low-warning safety warning information, the vehicle-mounted system will issue a high-risk safety warning prompt through the vehicle body display screen and voice equipment.

[0025] Furthermore, when the vehicle system receives a high-risk safety warning message, the vehicle system obtains whether the vehicle is in an automatic cruise state. If it is in an automatic cruise state, the remote control terminal performs automatic cruise release intervention and prompts the owner to manually take over and wait for rescue through the vehicle body display screen and voice equipment;

[0026] When the vehicle-mounted system receives low-risk safety warning information, high-alert safety warning information, and low-alert safety warning information, the remote terminal obtains the geographic location of the vehicle in the vehicle-mounted system and navigates to the nearest auto repair shop to the geographic location of the vehicle.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention proposes an automobile fault data evaluation system. The present invention realizes a comprehensive and accurate evaluation of automobile fault code data by integrating the collaboration of multiple modules such as data collection, analysis, evaluation and early warning, thereby ensuring the safety of automobile drivers, and can also significantly improve the efficiency of fault detection and reduce the time and cost of manual intervention. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only preferred embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0030] Figure 1 The figure is a schematic diagram of the overall structure of an automobile fault data evaluation system proposed in an embodiment of the present invention.

[0031] Figure 2 It is a schematic diagram of the overall flow of an automobile fault data evaluation method proposed in an embodiment of the present invention and executed in an automobile fault data evaluation system. DETAILED DESCRIPTION

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] Reference Figure 1 and Figure 2 The present invention provides an automobile fault data evaluation system, the system comprising a remote terminal and an on-board system, the remote terminal being in communication connection with the on-board system, the remote terminal being provided with a fault acquisition module, an analysis module, an evaluation module and an early warning module, the system being used to execute an automobile fault data evaluation method, the method comprising the following steps:

[0034] S1. Collect fault data on the vehicle system through a fault collection module;

[0035] S2, the analysis module analyzes the collected fault data and obtains the analysis results;

[0036] S3, the evaluation module evaluates the analysis result to obtain an evaluation result;

[0037] S4, the warning module sends safety warning information to the vehicle system based on the evaluation results;

[0038] S5. When the vehicle-mounted system receives the safety warning information, it prompts the safety warning information.

[0039] Exemplarily, various fault data on the vehicle-mounted system are collected in real time through the fault collection module. The fault collection can be carried out through corresponding sensors installed on the vehicle. The collected fault data can be analyzed by the analysis module to obtain analysis results. For the analysis results of the analysis module, the evaluation module adopts certain evaluation standards to evaluate the fault data and obtain evaluation results. For the evaluation results, the early warning module can send safety warning information to the vehicle-mounted system. The early warning module can detect changes in the evaluation results in real time. For the evaluation results, the vehicle-mounted system can be responsible for receiving the safety warning information sent by the early warning module, and making corresponding prompts and responses. Once an abnormal situation is found, an alarm can be issued to the driver through the display screen, sound prompts, etc. of the vehicle-mounted system. The vehicle-mounted system displays the content of the warning information through the display screen, and reminds the driver to pay attention to the vehicle status through sound, light, etc.

[0040] In step S1, the fault data includes the vehicle fault code, the vehicle model and the model of the component to which the fault code belongs.

[0041] For example, in order to quickly distinguish the fault information of different car models and facilitate maintenance personnel to quickly perform repairs, different fault information of the car can be quickly identified through the car fault code, so that maintenance personnel can quickly find the corresponding part model to which the fault code belongs.

[0042] In step S2, the following sub-steps are also included:

[0043] S21, the analysis module classifies the collected vehicle fault codes into active fault code type and inactive fault code type data;

[0044] S22, the analysis module matches the activity type fault code with the dangerous consequence corresponding to the activity type fault code stored in the remote terminal, and if they match, obtains the dangerous consequence analysis result of the stored activity type fault code;

[0045] S23. The analysis module matches the inactive type fault code with the warning consequence corresponding to the inactive type fault code stored in the remote terminal. If the match is consistent, the analysis result of the stored inactive type fault code warning consequence is obtained.

[0046] Exemplarily, the collected automobile fault codes are classified by the analysis module and divided into active fault code types and inactive fault code types. Active fault codes are faults that currently affect vehicle performance or safety, while inactive fault codes may be fault records that occurred in the past but have been repaired or no longer affect the current vehicle status. For fault codes classified as active types, the analysis module will match them with the active type fault code database stored in the remote terminal. The database contains various active type fault codes and their corresponding dangerous consequence descriptions. If the current active fault code matches a record in the database, the analysis module will directly obtain and store the record. The analysis module will obtain and store the dangerous consequence analysis results in the record so that it can be used for risk assessment in the subsequent assessment module. For fault codes classified as inactive types, the analysis module will also match them with the inactive fault code database stored in the remote terminal. The database contains inactive fault codes and their possible warning consequences, that is, potential problems or matters that may be caused by inactive faults in the future. If the inactive fault code matches a record in the database, the analysis module will obtain and store the warning consequence analysis results in the record to remind the owner or maintenance personnel to regularly check the relevant parts to prevent the recurrence of the fault or cause more serious problems.

[0047] In step S3, the following sub-steps are included:

[0048] S31, the evaluation module sets an activity score threshold and an inactivity score threshold;

[0049] S32, the evaluation module obtains the corresponding activity score in the dangerous consequence analysis result of the active type fault code, and obtains the corresponding inactive score in the early warning consequence analysis result of the inactive type fault code;

[0050] S33, the assessment module compares the obtained activity score with the set activity score threshold. If the activity score is greater than the set activity score threshold, a high-risk activity assessment result is obtained; if the activity score is less than the set activity score threshold, a low-risk activity assessment result is obtained;

[0051] S34. The evaluation module compares the obtained inactivity score with the set inactivity score threshold. If the inactivity score is greater than the set inactivity score threshold, an inactivity high warning evaluation result is obtained; if the inactivity score is less than the set inactivity score threshold, an inactivity low warning evaluation result is obtained.

[0052] Exemplarily, the evaluation module sets two score thresholds: an activity score threshold and an inactivity score threshold. These two thresholds are used to determine the risk level of active type fault codes and inactive type fault codes. The setting of the thresholds can be adjusted according to various factors such as vehicle type, brand, age and industry standards. The evaluation module obtains the corresponding activity score value in the dangerous consequence analysis result of the active type fault code and the corresponding inactivity score value in the warning consequence analysis result of the inactive type fault code. The score value can be obtained by comprehensive evaluation based on factors such as the type of fault code, the scope of impact, and the difficulty of repair. The evaluation module compares the obtained activity score value with the set activity score threshold. If the activity score value is greater than the set activity score threshold, it means that the activity type fault code has a higher risk, and the evaluation module will output an activity high-risk assessment result. If the activity score value is less than the set activity score threshold, it means that the risk of the activity type fault code is relatively low, and the evaluation module will output an activity low-risk assessment result. The evaluation module compares the obtained inactivity score value with the set inactivity score threshold. If the inactivity score value is greater than the set inactivity score threshold, it means that although the inactivity type fault code does not currently affect the vehicle performance, it has a higher potential risk or warning value, and the evaluation module will output an inactivity high warning evaluation result; if the inactivity score value is less than the set inactivity score threshold, it means that the potential risk or warning value of the inactivity type fault code is relatively low, and the evaluation module will output an inactivity low warning evaluation result.

[0053] In step S4, the warning module sends safety warning information to the vehicle system according to the evaluation result:

[0054] The early warning module matches the corresponding high-risk safety warning information, low-risk safety warning information, high-warning safety warning information, and low-warning safety warning information stored in the remote control terminal based on the received active high-risk assessment results, active low-risk assessment results, inactive high-warning assessment results, and inactive low-warning assessment results.

[0055] Exemplarily, the warning module receives the evaluation results from the evaluation module, and the evaluation results include four different categories: active high risk, active low risk, inactive high warning, and inactive low warning. According to the received evaluation results, the warning module searches for the corresponding warning information template in the remote control terminal. The template can be customized in advance according to different types of evaluation results, including high-risk safety warning information, low-risk safety warning information, high-warning safety warning information, low-warning safety warning information, etc. The matching process ensures that each evaluation result can find a corresponding and accurate warning information template. The warning module customizes specific and personalized safety warning information based on the found warning information template and the specific information of the current vehicle (such as vehicle model, fault code, component model, etc.). The customized safety warning information The information is sent to the vehicle-mounted system through the communication interface of the vehicle-mounted system (such as CAN bus, Bluetooth, Wi-Fi, etc.). After the vehicle-mounted system receives the safety warning information, it displays the warning information content to the driver through its display screen, sound prompts, flashing lights and other methods. The driver takes corresponding measures such as immediate parking inspection, contacting maintenance personnel, paying attention to driving safety, etc. according to the prompts of the warning information to deal with potential risks. The warning module can also record the sent safety warning information and its sending results such as whether it is successfully sent, whether the vehicle-mounted system receives and displays it, etc. in the remote control terminal for subsequent analysis and tracking. At the same time, the vehicle-mounted system can also feedback the driver's response to the remote control terminal, such as whether measures have been taken and whether the measures are effective, etc., so as to further optimize the performance and accuracy of the warning system.

[0056] In step S5, when the vehicle-mounted system receives the safety warning information, the prompt of the safety warning information is specifically as follows:

[0057] When the vehicle-mounted system receives high-risk safety warning information, low-risk safety warning information, high-warning safety warning information, and low-warning safety warning information, the vehicle-mounted system will issue a high-risk safety warning prompt through the vehicle body display screen and voice equipment.

[0058] Exemplarily, when the vehicle-mounted system identifies a high-risk safety warning message, the highest level warning mechanism is immediately activated. The warning message is displayed in a striking manner (such as a red background, flashing text, etc.) through the vehicle body display screen, and an emergency voice prompt is issued using a voice device to ensure that the driver can immediately notice and take corresponding countermeasures. Low-risk / high-warning / low-warning safety warning prompts: For low-risk safety warning information, high-warning safety warning information, and low-warning safety warning information, the vehicle-mounted system will also display the corresponding warning information on the vehicle body display screen, but may use different display methods (such as yellow background, non-flashing text, etc.) to distinguish their urgency. At the same time, the voice device will also issue corresponding voice prompts, but may not be as urgent or frequent as high-risk warnings. Continuous prompts and confirmations: Before the driver confirms that the warning message has been received or takes corresponding measures, the vehicle-mounted system may continue to display the warning message and issue voice prompts until the driver confirms that the message has been received and understands its content in some way (such as clicking a confirmation button, performing a specific operation, etc.).

[0059] When the vehicle system receives a high-risk safety warning message, the vehicle system determines whether the vehicle is in the automatic cruise state. If it is, the remote control terminal will cancel the automatic cruise and prompt the owner to take over manually and wait for rescue through the vehicle body display and voice equipment;

[0060] When the vehicle-mounted system receives low-risk safety warning information, high-alert safety warning information, and low-alert safety warning information, the remote terminal obtains the geographic location of the vehicle in the vehicle-mounted system and navigates to the nearest auto repair shop to the geographic location of the vehicle.

[0061] Exemplarily, when the on-board system receives high-risk safety warning information, the on-board system immediately checks whether the current car is in automatic cruise state. If the car is in automatic cruise state, the on-board system will send a signal to the remote control terminal, requesting the remote control terminal to release the automatic cruise. After receiving the request, the remote control terminal executes the automatic cruise release operation to ensure that the control of the vehicle is returned to the driver. At the same time, the on-board system displays the high-risk warning information in a striking manner (such as a red background, flashing text, etc.) through the vehicle body display screen, and uses a voice device to issue an emergency voice prompt, requiring the owner to immediately take over the vehicle manually and wait for rescue. The on-board system records the response process of this high-risk warning and may feed back relevant information to the remote Control terminal or related service department; when the vehicle-mounted system receives low-risk, high-warning or low-warning safety warning information, the remote terminal obtains the current geographical location information of the vehicle-mounted system, and uses the map service or built-in navigation system to find and determine the nearest auto repair shop to the geographical location of the car. The remote terminal provides navigation information to the driver and guides him to the nearest repair shop for inspection or repair. The vehicle-mounted system sends a warning message to the owner through the body display and voice equipment, and informs him that he has been navigated to the nearest repair shop, and recommends that the owner go for inspection as soon as possible. The vehicle-mounted system records the response process of this warning, and may feedback relevant information (such as navigation information, owner response, etc.) to the remote control terminal or related service department.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
