It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
An upgrade method and apparatus for an electronic control unit according to embodiments of the present application will be described in detail with reference to the accompanying drawings.
Fig. 1 is an upgrade method of an electronic control unit according to an embodiment of the present application, as shown in fig. 1, where the method includes:
s101, monitoring the upgrading state of an electronic control unit in a current vehicle;
s102, if the upgrading state of the electronic control unit is monitored to be an abnormal state, determining a file to be upgraded corresponding to the electronic control unit;
s103, verifying the integrity of the file to be upgraded, if the file to be upgraded is a missing file, determining an upgrading task corresponding to the file to be upgraded, and determining an influence factor corresponding to the file to be upgraded based on the upgrading task;

s105, if the target missing file corresponding to the file to be upgraded is obtained from the upgrade server, determining a target upgrade file according to the file to be upgraded and the target missing file, and upgrading the electronic control unit based on the target upgrade file.
Specifically, the upgrade method of the electronic control unit provided in this example is applied to vehicles including vehicles with automatic driving or intelligent driving (including passenger function vehicles (e.g., sedans, buses, wagons, etc.), cargo function vehicles (e.g., general trucks, vans, dump trucks, closed trucks, tank trucks, flatcars, container cars, dump trucks, special structure trucks), special vehicles (e.g., logistics distribution vehicles, automated guided vehicles AGVs, patrol cars, cranes, excavators, bulldozers, forklift trucks, road rollers, loaders, off-road engineering vehicles, armored vehicles, sewage treatment vehicles, sanitation vehicles, dust trucks, floor washing vehicles, watering vehicles, sweeping robots, meal delivery robots, shopping guide robots, mowers, golf carts, etc.), recreational vehicles (e.g., recreational vehicles, amusement park automatic driving devices, balance cars, etc.), rescue vehicles (e.g., fire fighting vehicles, ambulances, electric power emergency vehicles, engineering vehicles, etc.), and the like).
In the above example, the vehicle includes at least one Electronic Control Unit (ECU) that can be updated according to the update file.
In some examples, when the ECU performs the upgrade in step S101, the current vehicle may acquire the upgrade status of the electronic control unit in the current vehicle in real time, and if it is monitored that there is an incomplete upgrade issue for the electronic control unit, it is determined that the upgrade status of the electronic control unit is an abnormal status; if the electronic control unit is monitored to have no incomplete upgrading matters, determining that the upgrading state of the electronic control unit is a normal state.
If the upgrading state of the electronic control unit is detected to be an abnormal state, determining a file to be upgraded corresponding to the electronic control unit; it can be understood that after the electronic control unit is updated and interrupted due to power outage, system, network abnormality, other faults and the like, the file to be updated transmitted to the electronic control unit may have the conditions of missing, damage and the like, so as to avoid the influence on the stability of the electronic control unit caused by directly using the file to be updated with the problems, and further verification on the integrity of the file to be updated is required in this embodiment.
It can be appreciated that methods of verifying the integrity of a file to be upgraded include, but are not limited to: acquiring a target verification code (including but not limited to MD5 code of a file) transmitted by an upgrade server, generating a file verification code according to the file to be upgraded, comparing the target verification code with the file verification code, and if the target verification code is the same as the file verification code, obtaining the file to be upgraded as a complete file; otherwise, if the target verification code and the file verification code are different, the file to be upgraded is a complete file; the method for verifying the integrity of the file to be upgraded is not limited, and related personnel can flexibly select the method for verifying the integrity of the file to be upgraded according to actual requirements.
In some examples, if the file to be upgraded is a complete file, directly taking the file to be upgraded as a target upgrade file, and upgrading the electronic control unit based on the target upgrade file; in some examples, if the file to be upgraded is a missing file, determining an upgrade task corresponding to the file to be upgraded, where the upgrade task is used to determine a function of upgrading the electronic control unit; for example, the electronic control unit is an audio-visual electronic control unit, and the audio-visual electronic control unit includes: video function, audio function, brightness adjusting function, touch screen control function, etc., wherein if the upgrade task is to optimize the brightness adjusting function, the function of upgrading the electronic control unit is determined to be the brightness adjusting function.
After determining the upgrade task, determining an influence factor corresponding to the file to be upgraded based on the upgrade task, including: determining an importance score of the upgrade task in the electronic control unit, and determining a current stability score of the electronic control unit, wherein the stability score is used for representing the health condition of the electronic control unit; and determining an influence factor corresponding to the file to be upgraded according to the importance score and the stability score. Specifically, determining an importance score of an upgrade task in an electronic control unit includes: the corresponding relation between the preset function and the importance score and the upgrading function corresponding to the upgrading task determine the importance score of the upgrading task in the electronic control unit; for example, the electronic control unit is an audio-visual electronic control unit, wherein the audio-visual electronic control unit comprises: video function, audio frequency function, luminance adjustment function, touch screen control function etc. wherein video function, audio frequency function are the core function of audio-visual electronic control unit, consequently, relevant personnel can set up video function, audio frequency function's importance score and be X, luminance adjustment function, touch screen control function are not the core function of audio-visual electronic control unit, consequently, set up luminance adjustment function, touch screen control function's importance score as Y (wherein X > Y), after determining that the upgrading function that the upgrading task corresponds is luminance adjustment function, then determine that the importance score of upgrading task in electronic control unit is Y.
It can be appreciated that the present example is not limited to implementing the "determine importance score of upgrade task in electronic control unit" only by the above steps, and the related person may flexibly set the step of implementing the "determine importance score of upgrade task in electronic control unit" according to actual needs.
In some embodiments, a current stability score for the electronic control unit is determined, including, but not limited to: determining the number of times of breakdown of the electronic control unit in unit time, and determining a stability score of the electronic control unit based on the number of times of breakdown, wherein it can be understood that the smaller the number of times of breakdown of the electronic control unit in unit time is, the higher the stability score is; conversely, the more the electronic control unit collapses per unit time, the lower the stability score. Wherein the stability score is used to characterize the health of the electronic control unit.
After the importance score and the stability score are determined, determining an influence factor corresponding to the file to be upgraded based on the importance score and the stability score, wherein the higher the importance score is, the higher the influence molecule is, and the lower the importance score is, the lower the influence molecule is; the lower the stability score is, the higher the influence molecule is, the importance score and the weight of the stability score can be set based on the rule, and further the influence factor corresponding to the file to be upgraded is determined under the rule, wherein the specific calculation formula is as follows:
M＝X*A+Y*B；
wherein M is an influence factor, X is an importance score, A is an importance score weight, the value of A is greater than zero, Y is a stability score, B is a stability score, and the value of B is less than zero. It will be appreciated that this example is not intended to be limiting, and that the influence factors may be determined from the importance scores and the stability scores in the manner described above, and that the relevant personnel may be flexibly set according to actual needs.
It can be understood that according to the importance score and the stability score, the influence factors corresponding to the files to be upgraded are determined, so that the importance degree of the upgrading task in the electronic control unit and the stability degree of the electronic control unit are comprehensively considered, the effect of accurately acquiring the influence factors is realized, and the problem that the influence factors cannot be acquired in the related technology is avoided.
According to the technical scheme provided by the embodiment of the application, the upgrading state of the electronic control unit in the current vehicle is monitored; if the upgrading state of the electronic control unit is monitored to be an abnormal state, determining a file to be upgraded corresponding to the electronic control unit; verifying the integrity of the file to be upgraded, if the file to be upgraded is a missing file, determining an upgrading task corresponding to the file to be upgraded, and determining an influence factor corresponding to the file to be upgraded based on the upgrading task; the method comprises the steps of determining a target upgrading file according to the influence factors, upgrading the electronic control unit based on the target upgrading file, determining the influence factors corresponding to the file to be upgraded when the file to be upgraded is a missing file, determining the target upgrading file based on the influence factors, and realizing a plurality of target upgrading file acquisition modes, so that the problem of resource waste caused by repeated transmission of the same file due to direct re-acquisition of the target upgrading file from an upgrading server after the electronic control unit fails to upgrade caused by power failure and other anomalies is solved.
In some embodiments, as shown in fig. 2, determining the target upgrade file according to the impact factor includes:
s201, determining whether to obtain a target missing file corresponding to a file to be upgraded from an upgrade server according to an influence factor;
s202, if a target missing file corresponding to the file to be upgraded is obtained from the upgrade server, determining a target upgrade file according to the file to be upgraded and the target missing file.
In some examples, after determining the influence factor, determining whether to obtain a target missing file corresponding to the file to be upgraded from the upgrade server according to the influence factor; determining whether to obtain a target missing file corresponding to a file to be upgraded from an upgrade server according to an influence factor, wherein the target missing file comprises the following three conditions:
first case: if the target missing file corresponding to the file to be upgraded is obtained from the upgrading server, determining the target upgrading file according to the file to be upgraded and the target missing file, and upgrading the electronic control unit based on the target upgrading file, wherein the influence factor can determine the importance degree of the upgrading task corresponding to the file to be upgraded, if the influence factor is lower, the importance degree of the upgrading task corresponding to the current file to be upgraded is lower, so that the target missing file is directly obtained from the upgrading server, and the file to be upgraded is supplemented, thereby obtaining the target upgrading file, and further avoiding the problem of resource waste caused by repeated transmission of the same file because all the target upgrading files are required to be obtained from the upgrading server after upgrading faults occur.
Second case: if the target upgrade file is determined to be directly obtained from the upgrade server, the target upgrade file is directly obtained from the upgrade server, and the electronic control unit is upgraded based on the target upgrade file; specifically, when the target upgrade file is determined to be directly obtained from the upgrade server, deleting the current file to be upgraded, and directly upgrading the electronic control unit based on the target upgrade file after the target upgrade file is obtained; it can be understood that, the above-mentioned influence factor can determine the importance degree of the file to be upgraded corresponding to the upgrade task, if the above-mentioned influence factor is larger, it represents that the importance degree of the current file to be upgraded corresponding to the upgrade task is higher, so, in order to avoid the file to be upgraded itself from missing, and causing abnormal functions subsequently, the target upgrade file is directly obtained from the upgrade server again, and the problem of abnormal functions of the electronic control unit caused by directly upgrading according to the file to be upgraded is avoided.
Third case: if the target missing file corresponding to the file to be upgraded is not obtained from the upgrading server, and the target upgrading file is not obtained from the upgrading server, further judging whether the file to be upgraded can directly upgrade the electronic control unit, if the file to be upgraded can upgrade the electronic control unit, directly taking the file to be upgraded as the target upgrading file, and directly carrying out subsequent upgrading according to the target upgrading file; specifically, if the influence factor is determined to be lower than the preset threshold influence factor, directly determining that the target missing file corresponding to the file to be upgraded is not acquired from the upgrade server, and determining that the target upgrade file is not acquired from the upgrade server.
According to the technical scheme provided by the embodiment of the application, the upgrading state of the electronic control unit in the current vehicle is monitored; if the upgrading state of the electronic control unit is monitored to be an abnormal state, determining a file to be upgraded corresponding to the electronic control unit; verifying the integrity of the file to be upgraded, if the file to be upgraded is a missing file, determining an upgrading task corresponding to the file to be upgraded, and determining an influence factor corresponding to the file to be upgraded based on the upgrading task; the method comprises the steps of determining a target upgrading file according to the influence factor, upgrading the electronic control unit based on the target upgrading file, determining the influence factor corresponding to the file to be upgraded when the file to be upgraded is a missing file, and obtaining the target missing file from the upgrading server when the target missing file corresponding to the file to be upgraded is determined to be obtained from the server based on the influence factor judgment, so that the problem of resource waste caused by repeated transmission of the same file due to the fact that the target upgrading file needs to be obtained from the upgrading server again after the electronic control unit fails due to power failure and other anomalies is solved.
In some embodiments, as shown in fig. 3, determining whether to obtain a target missing file corresponding to a file to be upgraded from an upgrade server according to an impact factor includes:
s301, determining a preset target influence factor, and comparing the influence factor with the target influence factor;
s302, when the comparison result shows that the influence factor is lower than the target influence factor, determining to acquire a target missing file corresponding to the file to be upgraded from the upgrading server.
Specifically, a related person determines a target influence factor according to actual task requirements, then compares the influence factor determined by the example with the target influence factor, and when the comparison result is that the influence factor is lower than the target influence factor, acquires a target missing file corresponding to the file to be upgraded from the upgrade server.
It can be understood that when the influence factor is lower than the target influence factor, the influence factor is lower, and the importance degree of the current file to be upgraded corresponding to the upgrading task is lower, so that the target missing file is directly obtained from the upgrading server at the moment, the files to be upgraded are supplemented to obtain the target upgrading file, and further the problem of resource waste caused by repeated transmission of the same file because all the target upgrading files are required to be obtained from the upgrading server after the upgrading failure occurs is avoided.
When the comparison result is that the influence factor is not lower than the target influence factor, the target upgrade file is determined to be directly obtained from the upgrade server, the file to be upgraded is directly discarded at the moment, and after the target upgrade file is directly obtained from the upgrade server, the system upgrade is directly performed based on the target upgrade file.
According to the technical scheme provided by the embodiment of the application, a preset target influence factor is determined, and the influence factor and the target influence factor are compared; when the comparison result shows that the influence factor is lower than the target influence factor, determining to acquire a target missing file corresponding to the file to be upgraded from the upgrading server, and acquiring the target missing file from the upgrading server in the subsequent step, so that the problem of resource waste caused by repeated transmission of the same file due to the fact that in the related technology, after the upgrading failure occurs, all target upgrading files need to be acquired from the upgrading server is avoided.
In some embodiments, as shown in fig. 4, if the comparison result is that the impact factor is higher than the target impact factor, the method further includes:
s401, generating a target upgrade file acquisition request of a target upgrade file, and sending the target upgrade file request to an upgrade server;
s402, receiving a target upgrade file returned by the upgrade server aiming at the target upgrade file acquisition request.
Specifically, if the comparison result is that the influence factor is higher than the target influence factor, discarding the file to be upgraded, and directly obtaining the target upgrade file from the upgrade server, it can be understood that the influence factor can determine the importance degree of the upgrade task corresponding to the file to be upgraded, if the influence factor is larger, the importance degree of the upgrade task corresponding to the current file to be upgraded is higher, so that in order to avoid the defect of the file to be upgraded, which results in the subsequent function abnormality, the target upgrade file is directly obtained from the upgrade server again, and the problem of the function abnormality of the electronic control unit caused by directly upgrading according to the file to be upgraded is avoided.
In some examples, when it is determined that the target upgrade file is directly acquired from the upgrade server, an acquisition request corresponding to the target upgrade file is directly generated, the target upgrade file request is sent to the upgrade server, the upgrade server returns the target upgrade file to the vehicle after receiving the target upgrade file acquisition request, and the vehicle upgrades according to the target upgrade file.
According to the technical scheme provided by the embodiment of the application, a target upgrade file acquisition request of a target upgrade file is generated, and the target upgrade file request is sent to an upgrade server; the target upgrade file returned by the upgrade server aiming at the target upgrade file acquisition request is received, so that the target upgrade file is directly acquired from the upgrade server under the condition of high influence factor.
In some embodiments, as shown in fig. 5, obtaining, from an upgrade server, a target missing file corresponding to a file to be upgraded, includes:
s501, generating a missing file acquisition request according to a file to be upgraded, sending the missing file acquisition request to an upgrade server, analyzing the missing file acquisition request by the upgrade server, and transmitting a target missing file to a current vehicle according to an analysis result;
s502, receiving a target missing file transmitted by the upgrade server.
Specifically, generating the missing file acquisition request from the file to be upgraded includes, but is not limited to: and generating corresponding verification information (including but not limited to MD5 information) according to the file to be upgraded, and taking the verification information as a missing file acquisition request. It can be understood that the embodiment is not limited to a specific method for generating the missing file obtaining request according to the file to be upgraded, and may be flexibly set by related personnel.
After the missing file obtaining request is generated, the missing file obtaining request is sent to the upgrading server, the upgrading server is used for analyzing the missing file obtaining request, further obtaining a file to be upgraded existing on the vehicle currently, determining the missing file according to the file to be upgraded and the target upgrading file on the vehicle, and then transmitting the missing file to the current vehicle.
