Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a fault monitoring method, an electronic fuse, a computer device, and a storage medium. Background Art

[0002] As the electrification of vehicles continues to increase, the number and complexity of onboard electronic devices are also increasing. Abnormal operation of these electronic devices can lead to abnormal current flow, which in turn affects vehicle safety and reliability. Traditional electronic fuses only disconnect the circuit when the current exceeds a preset value, making fault diagnosis difficult. Therefore, how to proactively record abnormal information and improve the efficiency of fault diagnosis has become a technical challenge that needs to be addressed. Summary of the Invention

[0003] In view of this, embodiments of the present application provide a fault monitoring method, an electronic fuse, a computer device, and a storage medium.

[0004] In a first aspect, an embodiment of the present application provides a fault monitoring method, which is applied to an electronic insurance, wherein the electronic insurance is used to monitor and record the status of each electronic control unit in a vehicle, and the method includes:

[0005] monitoring electrical parameters of each of a plurality of electronic control units in the vehicle, the electrical parameters including voltage parameters and / or current parameters;

[0006] When it is monitored that the electrical parameters of at least one electronic control unit among the plurality of electronic control units include an abnormal parameter item, the abnormal parameter item is recorded.

[0007] The method provided in the embodiment of the present application is that the electronic insurance can monitor the electrical parameters of multiple electronic control units, can cover the electronic control units in the vehicle, and can monitor the electrical parameters of each electronic control unit in the vehicle to avoid missed fault detection. When there are abnormal parameter items, the electronic insurance can actively trigger the recording of abnormal parameter items, providing a data basis for fault diagnosis, reducing the time for fault location, and improving the efficiency of fault detection. The faulty electronic control unit can be located based on the abnormal parameter items, eliminating the need for maintenance personnel to check each one. The abnormal parameter items recorded by the electronic insurance can provide a basis for fault diagnosis, analyze the cause of the fault, avoid misjudgment caused by blindly replacing parts for testing, and reduce maintenance costs.

[0008] In conjunction with the first aspect, in one possible implementation, the electronic fuse is provided with multiple channels, each channel is mounted with a single electronic control unit, and monitoring the electrical parameters of each of the multiple electronic control units in the vehicle includes:

[0009] By monitoring the electrical parameters on the multiple channels, the electrical parameters of each of the multiple electronic control units in the vehicle are obtained.

[0010] In the method provided in the embodiment of the present application, the electronic insurance sets a corresponding channel for each electronic control unit, thereby improving the accuracy of fault monitoring of each electronic control unit. A single channel only mounts a single electronic control unit. When an abnormal electrical parameter of a certain channel is detected, it can be directly associated with the electronic control unit corresponding to the channel, without the need to additionally distinguish the signal mixing problem of multiple electronic control units in the same channel. The intermediate links in narrowing the fault range are reduced, and the efficiency of fault location is improved. When a certain channel fails, it does not affect the fault monitoring function of other channels. It is convenient for expansion. When a new electronic control unit is added, it only needs to create a new channel and mount the new electronic control unit, which has strong scalability.

[0011] In conjunction with the first aspect, in one possible implementation, before recording the abnormal parameter item, the method further includes:

[0012] For each of the plurality of electronic control units, when a parameter item in the electrical parameters of the electronic control unit is not within a reference threshold range, it is determined that the parameter item in the electrical parameters of the electronic control unit is abnormal.

[0013] The method provided in the embodiments of the present application sets a reference threshold range and compares the actual monitored parameter item with the set reference threshold range to determine whether the actual parameter item is abnormal, thereby improving the efficiency of determining whether the parameter item is abnormal. In addition, considering the diversity of electronic control units, corresponding reference threshold ranges can be set for different electronic control units to improve the accuracy of abnormal parameter item determination.

[0014] In combination with the first aspect or its corresponding embodiment, in one possible implementation, the electronic insurance is further provided with an internal memory, and the parameter items for recording abnormalities include:

[0015] The abnormal parameter items are stored in the internal memory.

[0016] The method provided in the embodiments of this application integrates internal memory directly into the electronic fuse, allowing data to be written within milliseconds of detecting an anomaly. Even if the vehicle's power supply is subsequently interrupted or the communication system fails, the stored anomaly parameters are retained, effectively preventing data loss. By directly reading the anomaly records in the internal memory to obtain the anomaly parameters, the efficiency of anomaly record reading is improved.

[0017] In conjunction with the first aspect or its corresponding embodiment, in one possible implementation, the parameter item for recording the abnormality further includes: recording a channel identifier and a maintenance duration; the channel identifier is used to distinguish between channels; and the method further includes:

[0018] Pre-set the mapping relationship between channels, electronic control units, and channel identifiers;

[0019] The mapping relationship is stored in the internal memory.

[0020] The method provided in the embodiment of the present application can record the channel identifier used to distinguish each channel and the duration of the abnormality while recording the abnormal parameter items. The fault type and risk level can be determined in more detail. For example, the duration can intuitively reflect the severity of the fault. The mapping relationship between the channel, the electronic control unit and the channel identifier can be preset. The preset mapping relationship is stored in the internal memory of the electronic insurance. When performing fault diagnosis, the faulty electronic control unit can be quickly determined, reducing the probability of misdiagnosis and improving the efficiency and accuracy of fault diagnosis.

[0021] In combination with the first aspect or its corresponding embodiment, in one possible implementation, the method further includes:

[0022] The channel and electronic control unit corresponding to the abnormal parameter item are determined according to the mapping relationship.

[0023] The method provided in the embodiment of the present application can quickly determine the channels and electronic control units corresponding to abnormal parameters based on a pre-set mapping relationship, thereby improving the efficiency of fault location.

[0024] In conjunction with the first aspect, in one possible implementation, monitoring the electrical parameters of each of the plurality of electronic control units in the vehicle includes:

[0025] When the electronic fuse is in a dormant state, using the electronic fuse to monitor electrical parameters of each of a plurality of electronic control units in the vehicle;

[0026] The method further includes: waking up the electronic fuse in a dormant state before recording the abnormal parameter item; and controlling the electronic fuse to enter a dormant state after recording the abnormal parameter item.

[0027] The method provided by the embodiments of the present application uses an electronic fuse in a dormant state to monitor the electrical parameters of each electronic control unit. The dormant electronic fuse is awakened only when abnormal electrical parameters need to be recorded. After recording is complete, the electronic fuse re-enters a dormant state, thereby reducing the power consumption of the electronic fuse. The electronic fuse achieves fault monitoring with low power consumption.

[0028] In a second aspect, the embodiments of the present application provide an electronic insurance, which comprises:

[0029] A first processing module is configured to monitor an electrical parameter of each of a plurality of electronic control units in a vehicle, the electrical parameter comprising a voltage parameter and / or a current parameter;

[0030] A second processing module is configured to record an abnormal parameter item when it is monitored that the electrical parameter of at least one of the plurality of electronic control units comprises the abnormal parameter item.

[0031] In a third aspect, the embodiments of the present application provide a computer device, which comprises a memory and a processor, the memory and the processor are communicatively connected with each other, the memory stores computer instructions, and the processor executes the computer instructions to perform the fault monitoring method of the first aspect or any of the corresponding embodiments thereof.

[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0039] The present application provides an embodiment of a fault monitoring method. It should be noted that the flowcharts shown in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowcharts, in some cases, the order shown or described can be different.

[0040] Figure 1 FIG. 1 is a flow chart of a fault monitoring method according to an embodiment of the present application. Figure 1 As shown, the fault monitoring method is applied to electronic insurance, which is used to monitor and record the status of each electronic control unit in the vehicle. The fault monitoring method includes the following:

[0041] S101: Monitoring electrical parameters of each of a plurality of electronic control units in a vehicle.

[0042] In the embodiment of the present application, the electrical parameters include voltage parameters and / or current parameters. In the embodiment of the present application, other parameter items can also be set according to actual needs.

[0043] In an embodiment of the present application, the electronic control unit is an ECU in a vehicle. The electronic fuse can be in a dormant state or an awake state. When the vehicle is in the dormant state, the electronic fuse also goes into dormancy, and the electrical parameters of each of the multiple electronic control units in the vehicle can be monitored while the electronic fuse is in the dormant state. When the vehicle goes into dormancy (i.e., when the vehicle stops sending network messages), the electronic fuse also goes into dormancy, ensuring minimal power consumption.

[0044] S102: When it is monitored that the electrical parameters of at least one electronic control unit among the plurality of electronic control units include an abnormal parameter item, the abnormal parameter item is recorded.

[0045] In an embodiment of the present application, when the electronic insurance monitors that the electrical parameters in all electronic control units do not include abnormal parameter items, the electronic insurance remains in a dormant state and does not perform operations such as recording.

[0046] In an embodiment of the present application, for each parameter item, an abnormal parameter item can be recorded in a time accumulation manner. The abnormal parameter items recorded can be stored in the form of a data table, recording the abnormal parameter items at different times. When the electrical parameters of the electronic control unit include abnormal parameter items, it indicates that there is a faulty electronic control unit, and the electronic control unit corresponding to the abnormal parameter item is the faulty electronic control unit. Recording abnormal parameter items includes recording voltage parameters and / or current parameters, as well as a unique identifier of the electronic control unit. In the present application, the unique identifier of the electronic control unit can be the channel identifier mentioned in the following embodiments.

[0047] In an embodiment of the present application, when it is monitored that the electrical parameters of at least one electronic control unit among a plurality of electronic control units include abnormal parameter items, the electronic insurance in a dormant state can be awakened, and the abnormal parameter items can be recorded through the electronic insurance in the awakened state. In an embodiment of the present application, it is also possible to control the electronic insurance to enter a dormant state after recording the abnormal parameter items. In an embodiment of the present application, the electronic insurance in a dormant state monitors the electrical parameters of each electronic control unit through the electronic insurance in the dormant state, and will actively awaken the electronic insurance in the dormant state only when it is necessary to record abnormal electrical parameters, and after the recording is completed, the electronic insurance re-enters the dormant state, thereby reducing the power consumption of the electronic insurance. The electronic insurance realizes fault monitoring under low power consumption. In an embodiment of the present application, the electronic insurance can be actively awakened by the abnormal parameter items, and the electronic insurance can be used to actively record abnormal parameter items.

[0048] The method provided in the embodiment of the present application is that the electronic insurance can monitor the electrical parameters of multiple electronic control units, can cover the electronic control units in the vehicle, and can monitor the electrical parameters of each electronic control unit in the vehicle to avoid missed fault detection. When there are abnormal parameter items, the electronic insurance can actively trigger the recording of abnormal parameter items, providing a data basis for fault diagnosis, reducing the time for fault location, and improving the efficiency of fault detection. The faulty electronic control unit can be located based on the abnormal parameter items, eliminating the need for maintenance personnel to check each one. The abnormal parameter items recorded by the electronic insurance can provide a basis for fault diagnosis, analyze the cause of the fault, avoid misjudgment caused by blindly replacing parts for testing, and reduce maintenance costs.

[0049] In one possible implementation, the electronic fuse is provided with multiple channels, each channel being equipped with a single electronic control unit. The monitoring of electrical parameters of each of the multiple electronic control units in the vehicle in S101 specifically includes:

[0050] By monitoring the electrical parameters on multiple channels, the electrical parameters of each electronic control unit in the vehicle are obtained.

[0051] In an embodiment of the present application, as an example, a corresponding electrical parameter acquisition device can be set on the channel, and the electrical parameters of the corresponding electronic control unit of the vehicle can be collected through the electrical parameter acquisition device set on the channel. For example, a voltage detection device and / or a current detection device can be set on each channel, and the voltage detection device can monitor the voltage of the electronic control unit mounted on the channel. The current detection device can monitor the current of the electronic control unit mounted on the channel. The voltage monitored by the voltage detection device on the channel and the current monitored by the current detection device can be used as the electrical parameters of the electronic control unit mounted on the channel. The electronic control unit set inside the electronic insurance can collect the electrical parameters on each channel, obtain the electrical parameters of each electronic control unit in the multiple electronic control units in the vehicle, and realize subsequent functions such as determining whether it is within the participation threshold range.

[0052] In the method provided in the embodiment of the present application, the electronic insurance sets a corresponding channel for each electronic control unit, thereby improving the accuracy of fault monitoring of each electronic control unit. A single channel only mounts a single electronic control unit. When an abnormal electrical parameter of a certain channel is detected, it can be directly associated with the electronic control unit corresponding to the channel, without the need to additionally distinguish the signal mixing problem of multiple electronic control units in the same channel. The intermediate links in narrowing the fault range are reduced, and the efficiency of fault location is improved. When a certain channel fails, it does not affect the fault monitoring function of other channels. It is convenient for expansion. When a new electronic control unit is added, it only needs to create a new channel and mount the new electronic control unit, which has strong scalability.

[0053] In one possible implementation, before recording the abnormal parameter item, the fault monitoring method further includes:

[0054] For each of the plurality of electronic control units, when a parameter item in the electrical parameters of the electronic control unit is not within a reference threshold range, it is determined that the parameter item in the electrical parameters of the electronic control unit is abnormal.

[0055] For each of the plurality of electronic control units, when parameter items in the electrical parameters of all the electronic control units are within a reference threshold range, it is determined that the parameter items in the electrical parameters of the electronic control units are all normal.

[0056] In the embodiments of the present application, it is necessary to pre-set a reference threshold range. Different reference threshold ranges are set for different electrical parameters. For example, when the electrical parameters include voltage parameters and current parameters, it is necessary to set a voltage reference threshold range corresponding to the voltage and a current reference threshold range corresponding to the current. The reference threshold range is the range of the electrical parameters of the electronic control unit in a normal state / non-fault state.

[0057] As an example, in order to improve the accuracy of the judgment, different reference threshold ranges can be set for different electronic control units. When performing threshold comparison, for a certain electronic control unit, its parameter item can be compared with its corresponding reference threshold range to determine whether the parameter item is within the reference threshold range. For example, when the electrical parameters include voltage parameters and current parameters, the corresponding current reference threshold range of electronic control unit 1 can be [a, b], and the corresponding voltage reference threshold range can be [c, d]. For electronic control unit 2, the corresponding current reference threshold range can be [e, f], and the corresponding voltage reference threshold range can be [g, h]. In the embodiment of the present application, the reference threshold range can be automatically adapted according to the vehicle model item or the addition and subtraction of functions.

[0058] As another example, when the ranges of electrical parameters of the electronic control unit monitored by the electronic insurance are basically the same in the normal state / non-fault state, only one reference threshold range can be set for one parameter item, which can improve the efficiency of judgment while ensuring accuracy.

[0059] The method provided in the embodiments of the present application sets a reference threshold range and compares the actual monitored parameter item with the set reference threshold range to determine whether the actual parameter item is abnormal, thereby improving the efficiency of determining whether the parameter item is abnormal. In addition, considering the diversity of electronic control units, corresponding reference threshold ranges can be set for different electronic control units to improve the accuracy of abnormal parameter item determination.

[0060] In an embodiment of the present application, if abnormal parameter items appear in multiple channels at the same time and are not within the reference threshold range, the electronic fuse will be awakened, and the abnormal parameter items of each channel will be recorded, the maintenance time will be maintained, and the abnormal parameter items will be sorted according to the size relationship of the parameter items (for example, the current size), and stored inside the electronic fuse.

[0061] In a possible implementation, the electronic insurance is further provided with an internal memory, and the abnormal parameter items recorded in S102 specifically include:

[0062] The abnormal parameter items are stored in the internal memory.

[0063] In an embodiment of the present application, abnormal parameter items can be stored in the form of a data table.

[0064] The method provided in the embodiments of this application integrates internal memory directly into the electronic fuse, allowing data to be written within milliseconds of detecting an anomaly. Even if the vehicle's power supply is subsequently interrupted or the communication system fails, the stored anomaly parameters are retained, effectively preventing data loss. By directly reading the anomaly records in the internal memory to obtain the anomaly parameters, the efficiency of anomaly record reading is improved.

[0065] In a possible implementation, the recorded parameter item of the exception further includes a channel identifier and a maintenance duration. The channel identifier is used to distinguish different channels. In the embodiment of the present application, the exception record recorded in the internal memory includes, in addition to the parameter item of the exception, the channel identifier corresponding to the parameter item of the exception and the maintenance duration of the parameter item exception. In addition, the start time and the end time of the parameter item exception can also be included. In the embodiment of the present application, the specific data type of the exception record is not limited, and can be set and modified according to actual needs, but should at least include the above-mentioned parameter item of the exception, the corresponding channel identifier and the maintenance duration.

[0066] In the embodiment of the present application, for the electronic control unit still in the fault state, the maintenance duration is the duration from the start time of the last fault to the current time. For the electronic control unit that has recovered to normal, the maintenance duration is the duration from the start time of the last fault to the end time (the time when the electronic control unit recovers to normal). In the embodiment of the present application, the electronic fuse can record historical exception records, and the historical exception records are stored in the internal memory. As an example, the historical exception records can include exception records in a preset historical time period (for example, one month, half a year).

[0067] In the embodiment of the present application, the same type of parameter item can be stored in order of size by means of time accumulation. As an example, for the current, the current can be recorded in order from large to small. For the voltage, the voltage can also be recorded in order from large to small.

[0068] In a possible implementation, the fault monitoring method further includes:

[0069] The mapping relationship between the channel, the electronic control unit and the channel identifier is set in advance. The mapping relationship is stored in the internal memory.

[0070] As an example, the channel identifier can be a letter, a number or a combination of letters and numbers, and can be a data identifier DID corresponding to the electronic control unit on the vehicle. In the present application, the specific form of the channel identifier is not limited, and as an example, the channel identifier corresponding to "channel 1" and "electronic control unit 1" is "001".

[0071] In the embodiment of the present application, the mapping relationship can be stored in the internal memory in the form of a data table.

[0072] The method provided in the embodiment of the present application can record the channel identifier used to distinguish each channel and the duration of the abnormality while recording the abnormal parameter items. The fault type and risk level can be determined in more detail. For example, the duration can intuitively reflect the severity of the fault. The mapping relationship between the channel, the electronic control unit and the channel identifier can be preset. The preset mapping relationship is stored in the internal memory of the electronic insurance. When performing fault diagnosis, the faulty electronic control unit can be quickly determined, reducing the probability of misdiagnosis and improving the efficiency and accuracy of fault diagnosis.

[0073] In one possible implementation, the fault monitoring method further includes:

[0074] The channel and electronic control unit corresponding to the abnormal parameter item are determined according to the mapping relationship.

[0075] In an embodiment of the present application, when performing fault diagnosis, the mapping relationship and the recorded abnormality record (abnormal parameter item) can be read from the internal memory, and the channel and electronic control unit corresponding to the abnormal parameter item can be determined based on the mapping relationship. The method provided in an embodiment of the present application can quickly determine the channel and electronic control unit corresponding to the abnormal parameter based on the pre-set mapping relationship, thereby improving the efficiency of fault location.

[0076] In the embodiments of the present application, a specific electronic control unit can be located through a data identifier. The DID is a 16-bit binary code (e.g., 0x1234) that uniquely identifies a specific type of abnormality record stored within the electronic fuse. Each faulty channel / electronic control unit has a unique DID (e.g., DID = 0x0001 corresponds to "abnormality record for channel 1," and DID = 0x0002 corresponds to "abnormality record for channel 2").

[0077] In the embodiment of the present application, the faulty channel and its connected electronic control unit can be confirmed by remotely reading the DID and locally reading the DID. The electronic insurance can also store the recorded abnormality records in the vehicle's non-volatile memory (NVM), and the electronic insurance can also retrieve the abnormality records corresponding to the DID from the NVM.

[0078] In one possible implementation, the fault monitoring method further includes:

[0079] After waking up the dormant electronic fuse, it generates a standardized fault message based on recorded abnormal parameters and other data. The electronic fuse then transmits the fault message to the telematics processor via the CAN bus. The telematics processor encrypts the data and pushes it to the anomaly monitoring platform via the network. Upon receiving the data, the cloud server parses the message content and, based on pre-set mapping relationships, automatically locates the faulty electronic control unit (ECU). It then sends an alert to the automaker's after-sales service and the owner via a web interface or mobile app (e.g., "Abnormal current leakage in the left front door ECU, currently persisting for 10 seconds, recommended for repair within 24 hours"). The anomaly monitoring platform also categorizes parameter values ​​(such as current) based on the severity of the excess (e.g., 1-2 times the threshold is a "general warning," >2 times is an "emergency warning"). This emergency alert triggers after-sales personnel to proactively contact the owner, preventing serious consequences such as battery drain.

[0080] Figure 2 This is an overall logic diagram of the fault monitoring method according to an embodiment of the present application. Figure 2 As shown, a dormant electronic fuse can monitor the electrical parameters of each electronic control unit. If an abnormal parameter is detected, the dormant electronic fuse is awakened and uses the electronic fuse to record the abnormality, including information such as the parameter, duration, and channel identifier. After recording is complete, the electronic fuse re-enters a dormant state. The corresponding channel and faulty electronic control unit in the abnormality record can also be determined based on a pre-stored mapping relationship.

[0081] Traditional fuse box: A traditional fuse box is a simple physical device that usually consists of fusible links (fuses) that protect the car's electrical circuits from damage caused by overloads and short circuits. It protects the electrical system by physically disconnecting the circuit to prevent excessive current.

[0082] The electronic insurance in the embodiment of this application:

[0083] Intelligent management: The electronic fuse box can monitor and control the status of the circuit through the internal electronic control unit, and detect parameters such as current and voltage in real time.

[0084] Fault diagnosis: When an abnormality is detected, the electronic insurance can record the abnormal parameter items or other data and issue a warning to the driver through the on-board diagnostic system.

[0085] Self-recovery function: The electronic insurance has a self-recovery function, which can automatically restore the normal working state of the electronic control unit on the vehicle after the fault is eliminated.

[0086] Remote monitoring: Through the vehicle network, the electronic insurance can communicate with other systems of the vehicle (such as the center console, engine management, etc.). The electronic insurance in the embodiment of this application can integrate multiple electronic control units and communicate with other systems through the vehicle network (such as the CAN bus) to achieve intelligent management and protection of the vehicle's electrical system.
