Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The action execution subject of each step in the ECU identification method provided by the embodiment of the present application may be the ECU identification system, the ECU identification device, and the ECU identifier provided by the embodiment of the present application, or may be a computer, a server, or the like in which the ECU identification system is built. For convenience of description, the action execution subject of each step in the ECU identification method provided by the embodiment of the present application is referred to as an ECU identification system, referred to simply as an identification system, provided by the embodiment of the present application.
Referring to fig. 1, fig. 1 is a flowchart of an ECU identification method according to an embodiment of the present disclosure.
The ECU identification method provided by the embodiment of the application can comprise the following steps:
step S101: identity information of the target vehicle is obtained.
It should be noted that the identity information in the embodiment of the present application refers to information related to the target vehicle. The identification system can directly read the identity information of the target vehicle in the target vehicle, and also can directly receive the identity information of the target vehicle and the like which are transmitted by the uploading port of the identification system and are input from the outside.
Step S102: and determining an ECU communication protocol corresponding to the identity information.
After the identification system acquires the identity information of the target vehicle, the ECU communication protocol corresponding to the identity information can be determined. Specifically, the identity information is sent to the cloud server, the cloud server retrieves the ECU communication protocol corresponding to the identity information, and sends the retrieved ECU communication protocol to the recognition system.
Step S103: and scanning the ECU communication protocol of the target vehicle by using the ECU communication protocol corresponding to the identity information, and determining and identifying the ECU information configured by the target vehicle according to the scanning result.
After determining the ECU communication protocol corresponding to the identity information, the identification system may perform step S103, and further determine the ECU information configured by the target vehicle. It should be noted that, here, the process of scanning the ECU communication protocol of the target vehicle by the identification system using the ECU communication protocol corresponding to the identity information is the same as that in the prior art, taking the example that one ECU communication protocol corresponding to the identity information scans one ECU communication protocol of the target vehicle, the specific scanning process may be: sending a diagnosis instruction to the ECU of the target vehicle through the ECU communication protocol corresponding to the identity information, judging whether the format and the content of a response instruction returned by the target vehicle through the ECU communication protocol of the target vehicle correspond to the diagnosis instruction, if so, judging that the ECU communication protocol of the target vehicle is the ECU communication protocol corresponding to the identity information, determining that the ECU of the target vehicle is the ECU corresponding to the ECU communication protocol corresponding to the identity information, if not, judging that the ECU communication protocol of the target vehicle is not the ECU communication protocol corresponding to the identity information, and determining that the ECU of the target vehicle is not the ECU corresponding to the ECU communication protocol corresponding to the identity information. In addition, there may be a plurality of ECU communication protocols corresponding to the identity information, and there may be a plurality of ECU communication protocols of the target vehicle, in which case, the identification system may scan each ECU communication protocol of the target vehicle in turn using one of the ECU communication protocols corresponding to the identity information each time until scanning of each ECU communication protocol of the target vehicle is completed using all the ECU communication protocols corresponding to the identity information; in some specific cases, the identification system may also combine a multithreading technique to scan each ECU communication protocol of the target vehicle using the ECU communication protocol corresponding to the identity information, where, in the case that the ECU communication protocol corresponding to the identity information carried by each thread is the same, the ECU communication protocol of the target vehicle scanned by each thread should be a different ECU communication protocol; under the condition that the ECU communication protocols corresponding to the identity information carried by each thread are different, the ECU communication protocol of the target vehicle scanned by each thread may be the same ECU communication protocol or different ECU communication protocols.
According to the ECU identification method, after the identity information of the target vehicle is obtained, the ECU communication protocol corresponding to the identity information can be determined, then the ECU communication protocol corresponding to the identity information is used for scanning the ECU communication protocol of the target vehicle, and the ECU information configured by the target vehicle is determined and identified according to the scanning result; the ECU communication protocol corresponding to the identity information can be determined without manual participation in the whole identification process, the problem that in the prior art, the relevant information of the vehicle is identified by mistake manually, the identification efficiency of the information of the ECU installed in the vehicle is reduced is solved, and the identification efficiency is improved to a certain extent.
In the ECU identification method provided in the embodiment of the present application, the step S102 of determining the ECU communication protocol corresponding to the identity information may specifically be:
and determining the ECU communication protocol corresponding to the identity information according to the pre-established corresponding relationship, wherein the corresponding relationship represents the relationship between different identity information and different ECU communication protocols.
In practical application, in the process of retrieving the ECU communication protocol corresponding to the identity information by means of the cloud server, the identification system needs to have better communication capability, and the cloud server needs to have better retrieval capability, which has higher requirements on the performance of the identification system and the cloud server. In addition, due to the diversity of the identity information and the ECU communication protocol, the memory space consumed for storing the correspondence may be large, and at this time, in order to save the memory space, the correspondence may be compressed and then stored, and of course, other methods for saving the memory space may be available, and the present application is not limited specifically herein.
In order to complete the identification of the ECU configured for the target vehicle when the ECU communication protocol corresponding to the identity information cannot be determined according to the pre-created correspondence relationship, the ECU identification method provided in the embodiment of the present application may further include:
if the ECU communication protocol corresponding to the identity information cannot be determined according to the corresponding relation, a certain number of different ECU communication protocols are randomly determined to be the ECU communication protocol corresponding to the identity information.
It should be noted that the number of different ECU communication protocols determined randomly may be determined according to actual needs, and may be a certain preset fixed value, such as 10, 20, etc.; the number of the ECUs possibly installed in the target vehicle may also be used, and in a specific application scenario, the number of the ECUs possibly installed in each vehicle may be saved in advance, and then the number of the different ECU communication protocols randomly determined for the target vehicle may be determined according to the number of the ECUs possibly installed in each vehicle. In addition, after the ECU information configured by the target vehicle is determined according to the scanning result, the corresponding relationship between the ECU communication protocol corresponding to the ECU information and the identity information of the target vehicle can be established and stored, so that when the target vehicle or the vehicle with the same specification as the target vehicle is subjected to ECU identification next time, the ECU communication protocol corresponding to the identity information of the target vehicle or the vehicle with the same specification as the target vehicle can be quickly determined according to the corresponding relationship between the ECU communication protocol corresponding to the ECU information and the identity information of the target vehicle, and the identification efficiency of the identification system for identifying the ECU information of the vehicle is accelerated to a certain extent.
In an ECU identification method provided in an embodiment of the present application, the identity information may include identification information.
The identification information refers to information which can distinguish different vehicles, and the ECU communication protocol corresponding to the identity information of the target vehicle can be quickly determined by the aid of the identification information. In a specific application scenario, the Identification information may be a VIN (Vehicle Identification Number), a trademark, a product label, or the like. When the identity information is the identification information, no matter the identification system determines the ECU communication protocol corresponding to the identity information by means of the cloud server or determines the ECU communication protocol corresponding to the identity information according to the preset corresponding relation, due to the uniqueness of the identification information, the ECU communication protocol corresponding to the identity information determined by the identification system according to the identification information is most fit with the ECU communication protocol of the target vehicle, and the accuracy of determining the ECU communication protocol corresponding to the identity information by the identification system can be improved by means of the identification information.
In the method for identifying the ECU provided by the embodiment of the application, the identity information can comprise brand vehicle types.
In practical applications, the identification information may also be a brand model, wherein the brand model includes a small-sized vehicle, a mini-sized vehicle, a medium-sized vehicle, and the like. The division range of the brand vehicle type is larger than the identification information, namely the brand vehicle type of a vehicle can be obtained after the identification information of the vehicle is obtained, and the identification information of the vehicle cannot be determined necessarily after the brand vehicle type of the vehicle is obtained, so that the success rate of determining the ECU communication protocol corresponding to the identity information by the identification system can be ensured by means of the brand vehicle type. In addition, the brand vehicle type may also be determined according to the identification information of the target vehicle, and in practical application, referring to fig. 2, the ECU identification method provided in the embodiment of the present application may include the following steps:
step S201: identification information of the target vehicle is acquired.
Step S202: and judging whether the brand and model of the target vehicle can be determined according to the identification information of the target vehicle, if so, executing step S203, and if not, executing step S204.
Step S203: and determining the ECU communication protocol corresponding to the brand and the model of the target vehicle as the ECU communication protocol corresponding to the identity information according to the corresponding relationship between the different brands and the different ECU communication protocols, and executing the step S205.
Step S204: and randomly selecting the ECU communication protocols corresponding to a certain number of brands and vehicles as the ECU communication protocols corresponding to the identity information, and executing the step S205.
Step S205: and scanning the ECU communication protocol of the target vehicle by using the ECU communication protocol corresponding to the identity information, and determining and identifying the ECU information configured by the target vehicle according to the scanning result.
In order to ensure the accuracy of determining the communication protocol of the ECU corresponding to the identity information by the identification system and also consider the success rate of determining the communication protocol of the ECU corresponding to the identity information by the identification system, in practical application, referring to fig. 3, another ECU identification method provided in the embodiment of the present application may include the following steps:

step S401: acquiring identification information of a target vehicle;
