During the monitoring time period, the operating status of each vehicle virtual device of the adjusted hardware testing system or the operating data corresponding to each vehicle virtual device is collected. For example, the operating data corresponding to the engine may be the engine speed, and the operating data corresponding to the water temperature sensor may be the water temperature value, etc., to obtain the system operating data of the adjusted hardware testing system.

[0041] S103: Send the system operation data to the vehicle terminal for processing to obtain the vehicle terminal alarm data.

[0051] See also Figure 2 The vehicle warning detection method shown includes:

[0052] S201. Obtain the type of alarm to be detected.

[0053] Specifically, different types of alarms to be detected correspond to different devices to be adjusted, and the device adjustment data corresponding to the devices to be adjusted are also different. Therefore, when detecting the vehicle-mounted terminal, the type of alarm to be detected needs to be determined first.

[0054] S202: Determine, according to the alarm type to be detected, at least one simulated alarm condition corresponding to the alarm type to be detected.

[0055] The simulated alarm conditions may be conditions required for various devices on the vehicle to alarm when simulating a vehicle failure.

[0056] Specifically, for different alarm types to be detected, different faults of the vehicle are used to be warned. Different faults correspond to different operating data of each device, and different faults correspond to different simulation conditions of the device. Therefore, it is necessary to determine at least one simulation alarm condition corresponding to the alarm type to be detected according to the alarm type to be detected. The determination method can be: by searching in a database, and the search algorithm includes but is not limited to: sequential search algorithm, block search algorithm, tree table search algorithm or hash search algorithm, etc., which is not limited in the embodiment of the present invention.

[0057] S203: Query according to each simulated alarm condition to obtain at least one device to be adjusted and device adjustment data corresponding to each device to be adjusted.

[0058] Specifically, according to the query of each simulated alarm condition, at least one device to be adjusted and the device adjustment data corresponding to each device to be adjusted are obtained. The device adjustment data may be the operating status of the adjusted device, the indicator light of the device, the data value of the device, the installation location of the device, or the description information of the connection relationship of the device, etc. By analyzing the text of each simulated condition, each device to be adjusted and the device adjustment data corresponding to each device to be adjusted are identified, and the text analysis method may be natural language processing, etc.

[0059] S204: Combine the alarm type to be detected, each device to be adjusted, and the device adjustment data corresponding to each device to be adjusted to generate device fault data.

[0060] Specifically, the alarm type to be detected, each device to be adjusted, and the equipment adjustment data corresponding to each device to be adjusted are combined; one alarm type to be detected may correspond to multiple devices to be adjusted, and one device to be adjusted may correspond to multiple equipment adjustment data; and one alarm type to be detected may have multiple adjustment schemes, and different adjustment schemes may correspond to different devices to be adjusted and the equipment adjustment data corresponding to the devices to be adjusted, to generate equipment failure data.

[0061] S205 . For each device to be adjusted, according to at least one device adjustment data corresponding to the device to be adjusted, adjust the corresponding vehicle virtual device in the hardware test system and run the adjusted hardware test system to obtain system operation data of the adjusted hardware test system.

[0062] S206: Send the system operation data to the vehicle terminal for processing to obtain the vehicle terminal alarm data.

[0063] S207: Compare the equipment failure data with the vehicle terminal alarm data to generate vehicle terminal detection information to detect whether the vehicle terminal has an abnormal alarm.

[0064] The embodiment of the present invention obtains the type of alarm to be detected; determines at least one simulated alarm condition corresponding to the type of alarm to be detected according to the type of alarm to be detected; obtains at least one device to be adjusted and device adjustment data corresponding to each device to be adjusted by querying according to each simulated alarm condition; combines the type of alarm to be detected and each device to be adjusted and the device adjustment data corresponding to each device to be adjusted to generate device failure data, determines different simulated alarm conditions for different types of alarm to be detected, adjusts corresponding equipment, refines the operation of vehicle alarm detection, and improves the accuracy of vehicle alarm detection.

[0065] Optionally, the system operation data is sent to the vehicle terminal for processing to obtain the vehicle terminal alarm data, including: obtaining standard test data, the standard test data includes at least one test device and the equipment alarm conditions corresponding to each test device; the system operation data is sent to the vehicle terminal, the vehicle terminal matches the system operation data with the equipment alarm conditions corresponding to each test device, and generates the vehicle terminal alarm data.

[0066] The standard test data may be the description information of the preset test equipment alarm. The test equipment may be the preset equipment to be tested for alarm. The equipment alarm condition may be the preset condition for the test equipment to reach the alarm state.

[0067] Specifically, standard test data is obtained. The standard test data includes at least one test device and the device alarm conditions corresponding to each test device. The standard test data can be obtained through industry experience or preset manually according to the device to be tested and its own needs. The system operation data is sent to the vehicle terminal. The vehicle terminal matches the system operation data with the device alarm conditions corresponding to each test device to generate vehicle terminal alarm data.

[0068] By acquiring standard test data, the standard test data includes at least one test device and the equipment alarm conditions corresponding to each test device; sending the system operation data to the vehicle terminal, the vehicle terminal matches the system operation data with the equipment alarm conditions corresponding to each test device, and generates vehicle terminal alarm data, and determines the vehicle equipment that needs to be adjusted due to the vehicle failure and the equipment alarm conditions corresponding to the vehicle equipment according to the standard test data, matches the data of each device running in real time of the system with the equipment alarm conditions, determines whether the equipment operation data is abnormal, and improves the accuracy of vehicle alarm detection.

[0069] Optionally, standard test data is obtained, the standard test data including at least one test device and equipment alarm conditions corresponding to each test device, including: obtaining at least one standard test text number; for each standard test text number, querying the test content corresponding to the standard test text number; and generating at least one test device and equipment alarm conditions corresponding to each test device based on the test content corresponding to each standard test text number.

[0070] The standard test text number may be a version number corresponding to the standard test data. The test content may be data describing the device alarm condition.

[0071] Specifically, according to the experience of industry experts, there are multiple versions of standard test data, and standard test text numbers and test contents can be preset as needed. The standard test text number corresponds to the test content one by one. Obtain at least one standard test text number; for each standard test text number, query the test content corresponding to the standard test text number; according to the test content corresponding to each standard test text number, it can be identified through a neural network to generate at least one test device and the device alarm condition corresponding to each test device. The neural network can be a convolutional neural network, a recurrent neural network, a long short-term memory network, or a generative adversarial neural network.

[0072] By obtaining at least one standard test text number; for each standard test text number, querying the test content corresponding to the standard test text number; generating at least one test device and the device alarm condition corresponding to each test device according to the test content corresponding to each standard test text number, the test content can be obtained as needed, thereby increasing the flexibility of vehicle alarm detection.

[0073] Optionally, the alarm type to be detected is an engine fault, and the equipment to be adjusted includes a water temperature sensor, a fuel injector, an air flow sensor, an intake device, and an exhaust device.

[0074] Among them, engine failure can be caused by material and process defects, unreasonable design, manufacturing problems and improper operation during use. These problems may cause the engine to not work properly, thus affecting the performance and safety of the vehicle.

[0075] Specific causes of engine failure: Sensor failure: Sensors include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or signal interruption, the car's ECU cannot accurately obtain engine data, causing the engine fault light to light up. Oil quality problem: If the fuel and oil are not added according to the manufacturer's requirements, it may cause engine wear, causing the fault light to light up. Poor combustion of the mixture: Spark plug failure, ignition coil failure, fuel pump failure, oil line blockage, etc. may all cause poor combustion of the mixture, which in turn causes carbon deposits or knocking in the engine, and eventually causes the fault light to light up. Boost problem: Problems such as damage to the intake boost pipe and turbocharger may also cause the engine fault light to light up. Intake problem: If the air filter is not clean and not cleaned regularly, it will cause problems with the intake, causing the engine fault light to light up. Exhaust problem: Failure of the rear oxygen sensor, three-way catalytic converter, exhaust camshaft and bearing bushing may all cause exhaust problems, causing the engine fault light to light up. Anti-theft system failure: If the car's electronic anti-theft system fails, or the anti-theft controller does not match the engine's electronic controller, the engine fault light will also come on.

[0076] The type of alarm to be detected is engine failure. The equipment to be adjusted includes water temperature sensor, fuel injector, air flow sensor, intake equipment and exhaust equipment. According to the type of alarm to be detected, the equipment to be adjusted is adjusted to simulate vehicle failure, so as to detect whether the alarm of the vehicle terminal is accurate.

[0077] Optionally, the hardware testing system includes: a hardware-in-the-loop testing system.

[0078] Among them, the hardware-in-the-loop test system can be a hardware-in-the-loop simulation system for vehicle terminal testing. The hardware-in-the-loop test system (HiL) uses a real-time processor to run a simulation model to simulate the operating state of the controlled object, connects to the ECU under test through an I / O interface, and performs comprehensive and systematic testing on the ECU under test.

[0079] Specifically, the test host can be the executor of vehicle alarm detection. The test host controls the HIL test system through the local area network, simulates the BMS, VCU, MCU and other controllers, and creates real faults, such as temperature difference alarm, battery high temperature alarm, vehicle energy storage device overvoltage alarm, vehicle energy storage device undervoltage alarm, SOC low alarm, single cell overvoltage alarm, single cell undervoltage alarm, SOC high alarm, SOC jump alarm, rechargeable energy storage system mismatch alarm, battery cell consistency difference alarm, insulation alarm, DC-DC temperature alarm, brake system alarm, DC-DC status alarm, drive motor controller temperature alarm, high voltage interlock status alarm, drive motor temperature alarm, vehicle energy storage device overcharge, etc. The vehicle terminal can receive these real fault data through the CAN bus, process the fault data, and generate vehicle terminal alarm data.

[0080] By simulating the actual vehicle environment through the hardware-in-the-loop test system, the system operation data can be closer to the real environment, thereby improving the accuracy of vehicle alarm detection.

[0081] Optionally, the equipment fault data and the vehicle terminal alarm data are compared to generate vehicle terminal detection information to detect whether the vehicle terminal has an abnormal alarm, including: obtaining the equipment fault data and the vehicle terminal alarm data; comparing the alarm type to be detected in the equipment fault data with the vehicle alarm type in the vehicle terminal alarm data to obtain a type comparison result; comparing the equipment adjustment data corresponding to each device to be adjusted in the system operation data with each abnormal device in the vehicle terminal alarm data and the abnormal information corresponding to each abnormal device to obtain a data comparison result; generating the vehicle terminal detection information based on the type comparison result and the data comparison result to detect whether the vehicle terminal has an abnormal alarm.

[0082] The type comparison result may be the result of comparing the alarm type to be detected in the equipment fault data with the vehicle alarm type in the vehicle terminal alarm data. The data comparison result may be the result of comparing the equipment adjustment data corresponding to each device to be adjusted in the system operation data with each abnormal device in the vehicle terminal alarm data and the abnormal information corresponding to each abnormal device.

[0083] Specifically, the equipment failure data and the vehicle terminal alarm data are obtained; the alarm type to be detected of the equipment failure data is compared with the vehicle alarm type of the vehicle terminal alarm data to obtain a type comparison result, and it is determined whether the type of the alarm to be detected is the same as the alarm type identified by the vehicle terminal. If they are the same, it indicates that the alarm type identified by the vehicle terminal is accurate. Then the equipment adjustment data corresponding to each device to be adjusted in the system operation data is compared with each abnormal device and the abnormal information corresponding to each abnormal device in the vehicle terminal alarm data to obtain a data comparison result, and then it is determined whether the abnormal data of each device identified by the vehicle terminal is consistent with the operation data of the pre-adjusted device. If they are consistent, it indicates that the vehicle terminal accurately identifies the abnormal data of the device and can correctly alarm. Otherwise, it indicates that the vehicle terminal cannot accurately identify the abnormality of the device. According to the type comparison result and the data comparison result, the vehicle terminal detection information is generated to detect whether the vehicle terminal has an abnormal alarm.

[0084] By acquiring equipment fault data and vehicle terminal alarm data; comparing the alarm type to be detected in the equipment fault data with the vehicle alarm type in the vehicle terminal alarm data to obtain a type comparison result; comparing the equipment adjustment data corresponding to each device to be adjusted in the system operation data with each abnormal device in the vehicle terminal alarm data and the abnormal information corresponding to each abnormal device to obtain a data comparison result; generating vehicle terminal detection information based on the type comparison result and the data comparison result to detect whether the vehicle terminal has an abnormal alarm, and determining the accuracy of the vehicle terminal detection data through multi-dimensional data comparison, thereby improving the accuracy of vehicle alarm detection.
