Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Several embodiments of the invention are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The following embodiments can be applied to the determination system of the vehicle configuration module shown in fig. 1, where the determination system of the vehicle configuration module shown in fig. 1 includes an after-market diagnostic apparatus, a server, and a vehicle.
In particular, the after-market diagnostic device may be communicatively coupled to a server over a 4G or 5G network to enable access to the server for obtaining configuration information (e.g., configuration tables) for the vehicle. The after-sale diagnostic instrument is a vehicle diagnostic instrument generally used by a 4s shop or a maintenance department authorized by a manufacturer, a diagnostic interface is generally configured on a vehicle, and the after-sale diagnostic instrument can diagnose the vehicle by connecting the diagnostic interface of the vehicle. The diagnosis process is that the after-sale diagnosis instrument issues a diagnosis instruction to the whole vehicle CAN network of the vehicle through a diagnosis interface of the vehicle so as to read a fault code of an electronic module accessed to the whole vehicle CAN network and complete the diagnosis.
It should be noted that the configuration shown in FIG. 1 does not constitute a limitation on the determination system of the vehicle configuration module, which in other embodiments may include fewer or more components than shown, or some components may be combined, or a different arrangement of components.
Example one
Referring to fig. 2, a method for determining a vehicle configuration module according to a first embodiment of the present invention is shown, and is applied to an after-market diagnostic apparatus, where the after-market diagnostic apparatus is in communication connection with a server, and the method specifically includes steps S01-S04.
And step S01, acquiring the unique identification information of the target vehicle, and acquiring corresponding whole vehicle configuration information from the server according to the unique identification information, wherein the whole vehicle configuration information comprises all electronic module information which can be configured in the vehicle type corresponding to the target vehicle.
The unique identification information can be but is not limited to a frame number, a license plate number, an engine number and the like, the configuration information of the whole vehicle can be but is not limited to be presented in the form of a configuration table, a configuration list and the like, the electronic module information at least comprises identification and diagnosis identification information of the electronic module, the identification of the electronic module can be but is not limited to a name, a model, an English short and the like, and the diagnosis identification information of the electronic module can be a diagnosis ID.
It should be noted that, because different configuration versions exist in the same vehicle type, for example, a top configuration version, a middle-high configuration version, a low configuration version, and the like, there is a certain configuration difference between the versions. Conventionally, a configuration table needs to be made for different configuration versions, which is inefficient and prone to error, for example, a designer wrongly writes an electronic module, which is originally installed only in the top-configuration version, into the configuration table in the middle-high-configuration version, which leads to subsequent diagnosis errors, and this situation is often found in an actual scene.
Therefore, in the embodiment of the invention, because the subsequent diagnostic instrument can automatically identify the electronic modules actually configured by the target vehicle, designers can record all the information of the electronic modules which can be configured in the same vehicle type in the same vehicle configuration table, namely can record the information of the electronic modules which can be configured in each configuration version in the same vehicle configuration table, so that the preparation efficiency of the configuration table is improved, and errors are avoided.
During specific implementation, while the whole vehicle configuration information is uploaded to the server, the unique identification information of the corresponding vehicle needs to be associated and uploaded together. Therefore, the whole vehicle configuration information corresponding to the vehicle can be quickly acquired according to the unique identification information of the vehicle.
It should be noted that, in this embodiment, since all the electronic module information that may be configured for the same vehicle type is recorded in the same vehicle configuration table, in order to avoid the leakage of the entire configuration, the downloading of the vehicle configuration table must have a certain security supervision, and therefore, in some optional cases of the present invention, the step of obtaining the corresponding vehicle configuration information from the server according to the unique identification information specifically includes:
sending a data downloading request to the server, wherein the data downloading request comprises the unique identification information and an authorization code of the after-sales diagnostic apparatus;
and receiving the finished automobile configuration information issued by the server, wherein the finished automobile configuration information is issued after the server successfully verifies the authorization code.
That is to say, when the after-sale diagnostic device requests the server to download the vehicle configuration information of a certain vehicle type, the server needs to automatically upload the pre-stored authorization code to the server, and the server can verify the authorization code, and only if the verification is successful, the after-sale diagnostic device is expected to download. The authorization code of the after-sale diagnostic instrument can be obtained by authorization of a 4S store or a manufacturer, so that the configuration information of the whole vehicle can be downloaded from the server only by the authorized after-sale diagnostic instrument, and the configuration information of the whole vehicle is prevented from being maliciously stolen.
Step S02, extracting information of each electronic module from the vehicle configuration information to determine all possible configured target electronic modules of the target vehicle and their diagnostic identification information.
In specific implementation, characters in a finished automobile configuration table can be extracted based on OCR character recognition, and matching is performed based on prestored keywords to extract information of each electronic module in finished automobile configuration information; or, each piece of electronic module information can be sequentially recorded in the configuration table of the whole vehicle according to the serial number, and then each piece of electronic module information is sequentially extracted based on the serial number; or storing the information of each electronic module in the form of an Excel table, and extracting each electronic module information in the vehicle configuration information column by column based on the table.
It should be noted that, all the electronic module information extracted in step S02 may include all the electronic modules configured in the entire system of the vehicle, and not the electronic modules actually configured in the target vehicle, for this reason, the following steps S03 and S04 are also required to further confirm the electronic modules capable of communicating normally and actually configured in the target vehicle from all the electronic module information extracted in step S02.
Step S03, sending a preset diagnosis instruction to each of the target electronic modules according to the diagnosis identification information of the target electronic module.
In particular, with the diagnostic ID of each electronic module known, a diagnostic instruction may be sent to each target electronic module. In this embodiment, in order to ensure reliability, the same preset diagnosis instruction, for example, a $ 1001 instruction (change service), is uniformly sent to each target electronic module, and the preset diagnosis instruction is transmitted to each target electronic module through the entire vehicle CAN network, and then the response state of each target electronic module to the preset diagnosis instruction is monitored.
Step S04, determining the electronic modules capable of communicating normally actually configured by the target vehicle according to the response states of all the target electronic modules to the preset diagnosis instruction.
It should be understood that after receiving the preset diagnosis instruction, the electronic module capable of normal communication actually configured by the target vehicle inevitably responds to the preset diagnosis instruction, and the response result is also transmitted to the after-sales diagnostic apparatus through the entire vehicle CAN network, and the corresponding preset diagnosis instruction of the electronic module not actually configured by the target vehicle is a null instruction (no one receives), and there is no corresponding response, so that the after-sales diagnostic apparatus CAN confirm that the electronic module capable of normal communication is actually configured by the target vehicle according to the response states of all the target electronic modules to the preset diagnosis instruction.
In summary, in the method for determining a vehicle configuration module in the above embodiment of the present invention, the entire vehicle configuration information is obtained from the server through the unique identification information of the vehicle, so as to determine all target electronic modules that may be configured by the target vehicle and the diagnosis identification information thereof, then a preset diagnosis instruction is sent to each target electronic module based on the diagnosis identification information of each target electronic module, and finally the electronic module actually configured by the vehicle is determined according to the response state of the target electronic module to the preset diagnosis instruction. In addition, the entire system configuration of the same vehicle type is integrated into the same whole vehicle configuration information, so that only one configuration table exists in the server for the same vehicle type, the required configuration information can be downloaded from the server quickly, the capacity pressure of the server can be reduced, designers do not need to make one configuration table for vehicles with different configurations of the same vehicle, and the overall working efficiency is improved.
Example two
Referring to fig. 3, a method for determining a vehicle configuration module according to a second embodiment of the present invention is shown, which is applied to an after-market diagnostic apparatus, where the after-market diagnostic apparatus is in communication connection with a server, and the method specifically includes steps S11 to S17.
And step S11, acquiring the unique identification information of the target vehicle, and acquiring corresponding whole vehicle configuration information from the server according to the unique identification information, wherein the whole vehicle configuration information comprises all electronic module information which can be configured in the vehicle type corresponding to the target vehicle.
Step S12, extracting information of each electronic module from the vehicle configuration information to determine all possible configured target electronic modules of the target vehicle and their diagnostic identification information.
Step S13, sending a preset diagnosis instruction to each of the target electronic modules according to the diagnosis identification information of the target electronic module.
And step S14, receiving an affirmative response or a negative response of the target electronic module to the preset diagnosis instruction, and sending the corresponding preset diagnosis instruction to the target electronic module without response once every preset time until a preset stop condition is met.
And the preset sending stop condition is that a positive response is received, a negative response is received, or the sending times reach preset times.
That is, in the present embodiment, the response states of the target electronic module with respect to the preset diagnosis command include three types, namely, positive response, negative response and no response, the target electronic modules capable of making positive response and negative response are all normally communicable electronic modules actually configured by the target vehicle, and the target electronic module without response is an electronic module not actually configured by the target vehicle.
It should be understood that, because there are many electronic modules connected to the entire vehicle CAN network, and the entire vehicle CAN network is also easily affected by external electromagnetic wave interference signals, there may be abnormal situations that the diagnosis instruction is not successfully sent to the target electronic module, or the diagnosis instruction is interfered and fails in the transmission process, and the like, and at this time, a no-response situation will occur, which results in misunderstanding that the target electronic module is not actually configured for the vehicle. Based on the phenomenon, the embodiment sends the corresponding preset diagnosis instruction once every preset time for the target electronic module without response, and the electronic module which is not actually configured for the target vehicle is not finally determined until the positive response or the negative response made by the target electronic module is received or the sending times reach the preset times, so that the misjudgment phenomenon caused by single probabilistic influence is avoided, and the accuracy and the reliability are greatly improved.
Step S15, finding out the electronic modules with the acknowledgement status being positive acknowledgement and negative acknowledgement from all the target electronic modules according to the acknowledgement status of all the target electronic modules for the preset diagnosis instruction, so as to obtain the electronic modules which are actually configured by the target vehicle and can normally communicate.
And step S16, acquiring a configuration list table corresponding to the unique identification information, wherein the configuration list table contains all electronic module options which can be configured for the vehicle type corresponding to the target vehicle.
The configuration list table can also be downloaded from the server according to the unique identification information of the vehicle, and mainly comprises all electronic module options which are possible to be configured and corresponding to the vehicle type of the target vehicle, wherein the electronic module options are composed of English abbreviation and hook options of the electronic module, as shown in fig. 4. Aiming at the situation, the configuration list table can be also manufactured by designers and is associated and stored in the server along with the configuration information of the whole vehicle; or, the configuration list table may also be obtained by the server based on recognition of the vehicle configuration information, that is, english acronyms of the electronic modules in the vehicle configuration information are automatically extracted, so that the corresponding configuration list table is automatically formed.
As another implementation manner, the configuration list table may also be obtained locally, that is, after the step of extracting each electronic module information from the entire vehicle configuration information (step S12), the configuration list table may be automatically generated locally based on all the extracted electronic module information. Alternatively, all electronic modules (not classified into vehicle types) on the market can be recorded on the same configuration list table, that is, all vehicles correspond to one configuration list table.
And step S17, checking the electronic module options corresponding to the normally communicable electronic modules actually configured by the currently determined target vehicle in the configuration list table.
That is, after the electronic module capable of communicating normally and configured for the actual configuration of the target vehicle is determined, the electronic module capable of communicating normally and configured for the actual configuration of the target vehicle is automatically checked in the configuration list table, so that the maintenance personnel can quickly and directly know the electronic module configured for the actual configuration of the target vehicle according to the checking content on the configuration list table, and the subsequent maintenance and diagnosis operations are facilitated. In some optional examples, the configuration list table may further display a diagnosis ID corresponding to the electronic module for subsequent diagnosis.
In the embodiment, the normally communicable electronic module actually configured by the target vehicle is fed back to the maintenance personnel through the configuration list table, so that the maintenance personnel can perform the next diagnosis and maintenance according to the configuration list table. In other optional examples, a corresponding fault diagnosis instruction may be automatically generated for a fault description (e.g., abnormal sleep) of the vehicle, and the fault diagnosis instruction is sent to the currently confirmed electronic module capable of normal communication, which is actually configured for the target vehicle, so that after the electronic module of the actual configuration of the target vehicle is determined, vehicle diagnosis is automatically completed based on the fault description of the vehicle, and thus, a process of displaying a configuration list table and manually diagnosing by a serviceman based on the configuration list table may be omitted, and efficiency is improved.
Further, in some optional embodiments of this embodiment, the step of extracting information of each electronic module from the vehicle configuration information to determine the target electronic modules and the diagnosis identification information thereof of all possible configurations of the target vehicle includes:
extracting information of each electronic module from the configuration information of the whole vehicle;
determining the energy type of the target vehicle according to the unique identification information of the target vehicle, wherein the energy type comprises fuel oil, electric energy and mixed energy, namely corresponding to a fuel oil vehicle, an electric vehicle and a mixed vehicle;
and screening out the electronic module information which is impossible to configure the energy type of the target vehicle from all the extracted electronic module information according to the energy type of the target vehicle so as to determine all the target electronic modules which are possible to configure by the target vehicle and the diagnosis identification information thereof.
More specifically, the step of screening out the electronic module information, of which the energy type of the target vehicle is unlikely to be configured, from among all the extracted electronic module information specifically includes:
acquiring a preset electronic module information set corresponding to the energy type of the target vehicle, wherein the preset electronic module information set comprises electronic module information which cannot be configured by the energy type of the target vehicle;
all the extracted electronic module information is combined into a target electronic module information set;
calculating the intersection of the preset electronic module information set and the target electronic module information set;
and deleting the electronic module information in the intersection from the target electronic module information set.
That is to say, in this embodiment, the fuel types of the vehicles are further distinguished, so as to screen out the electronic module information that the energy type of the target vehicle is not likely to be configured from all the electronic module information extracted from the entire vehicle configuration information, for example, a vehicle type has a fuel charge and an electric charge, when the target vehicle is the fuel charge of the vehicle type, the electronic module (such as a power battery pack management module) that only the electric charge is configured CAN be removed from all the electronic module information in the entire vehicle configuration information of the target vehicle, thereby reducing the number of the target electronic modules that are likely to be configured by the target vehicle, further reducing the number of the preset diagnosis instructions that are subsequently generated to the target vehicle, reducing the transmission burden of the entire vehicle CAN network, and improving the response efficiency.
