Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
The automobile system scanning method provided by the embodiment of the invention can be applied to automobile diagnosis equipment and an automobile-mounted ECU (electronic control unit) of an automobile, and is used for realizing automobile system scanning. Among them, the automobile diagnosis apparatus is an apparatus for diagnosing or scanning an automobile system. The onboard ECU is a microcontroller on the vehicle.
In an embodiment, as shown in fig. 1, a method for scanning a vehicle system is provided, which is described by taking the vehicle diagnostic apparatus in fig. 7 as an example, and includes the following steps performed by the vehicle diagnostic apparatus:
s10: and sending a system query request to the vehicle-mounted ECU, wherein the system query request comprises a part number query command corresponding to a preset system model.
Among them, an on-board ECU (Electronic Control Unit, ECU for short) is a microcontroller on the vehicle and is used to Control the vehicle system. Automotive systems include, but are not limited to, engine systems and transmission systems, among others. The system query request is a request for querying an automotive system. The preset system model is a model which is preset by a user and corresponds to an automobile system. The part number query command is a query command corresponding to a preset system model and is used for querying the part number of the automobile system corresponding to the preset system model. It should be noted that the part number query command is set by the user in a customized manner and is stored in the memory of the automobile diagnostic apparatus. It is understood that the number of the part number query commands in the system query request is at least one.
Taking an engine system as an example, for a certain vehicle type of automobile, the engine system can select and configure any engine system model supported by the vehicle type on the market, and therefore, a user can firstly determine which engine system models can be configured for the current vehicle type by collecting data, for example, the vehicle type a can select 5 engine system models corresponding to the installed engine system, and the system query request includes 5 engine system-based part number query commands corresponding to the 5 engine system models. The setting mode of the part number query command of other systems is similar to that of the sender system, and is not described herein.
The automobile diagnosis device sends a system query request to the vehicle-mounted ECU to query an automobile system in the automobile, and the system query request comprises a part number query command corresponding to a preset system model, and the part number query command corresponds to the preset system model in all automobile models, so that the automobile diagnosis device can query the automobile system corresponding to all automobile models in the market in a way of acquiring the system part number of the automobile system through the part number query command, and the applicability of the automobile diagnosis device in the automobile system query can be improved.
S20: and acquiring system response information which is sent by the vehicle-mounted ECU and corresponds to the part number inquiry command.
The system response information is formed by the vehicle-mounted ECU responding to the part number inquiry command. Specifically, the system response information acquired by the automobile diagnostic equipment is the vehicle-mounted ECU response and the part number query command. As an example, the automobile diagnostic device obtains system response information corresponding to the part number query command sent by the vehicle-mounted ECU, which indicates that a system part number corresponding to the automobile system actually detected by the vehicle-mounted ECU exists in the part number to be queried, and the automobile diagnostic device subsequently processes the system response information to obtain the system part number actually existing in the automobile system, so as to further scan or diagnose the automobile system through the system part number.

S30: and analyzing the system response information to acquire the system part number.
The system part number is a hardware number corresponding to an automobile system actually existing or applied in the automobile and is used for uniquely identifying one automobile system.
It should be noted that the system response message is actually a string of characters. And the automobile diagnosis equipment analyzes the part number character string in the system response information through the character string analysis rule to obtain the system part number. The part number character string is a character string corresponding to the system part number. The character string analysis rule is preset by a user, and system response information is analyzed into a rule of a part number character string corresponding to a system part number. The character string parsing rule may be a rule for parsing the system response information into a part number character string corresponding to the system part number according to the target start position and the target character string length. The target starting position is the starting position of the part number string. The target string length is the length of the part number string.
For example, the string corresponding to the system response information is res 8F F0135A 0338393636332D 453145353120208D, the target start position 38 starts to obtain a target string length 38393636332D 4531453531 as the part number string, and the auto diagnostic device further processes the part number string 38393636332D 4531453531 to obtain the system part number. Understandably, the system part number is acquired by analyzing the system response information through the character string analysis rule, so that the accuracy rate in the process of acquiring the system part number is improved.

The matching method of the system part number and the target system may be that the system part number and the target system are matched through a matching rule preset by a user, and specifically, the system part number and the target system may be matched by using a part number matching table stored in a memory of the automobile diagnosis device in advance by the user. The part number matching table comprises configuration matching data, and the configuration matching data comprises a one-to-one correspondence relationship between configuration part numbers and automobile systems, or a plurality of system part numbers correspond to the matching relationship between single automobile systems. The configuration part number is a preset system part number. For example, the engine system may correspond to multiple engine models or the engine system may correspond to a single engine model, where each engine model corresponds to a system part number.
As an example, the configuration match data may be a table of data that correlates all system part numbers to all automobile systems. The automobile diagnosis device can match the system part number with the target system through the configuration matching data pre-stored in the automobile diagnosis device memory, can quickly and accurately determine the target system matched with the system part number, and improves the efficiency and accuracy of positioning the automobile system.
Further, the automobile diagnosis device matches the system part number with the target system by configuring matching data, and after the target system is determined, the target system and the system part number corresponding to the target system are added into a preset system scanning result list. It can be understood that, since the preset system scanning result list includes the corresponding relationship between the automobile system and the system part number, the target system and the system part number corresponding to the target system are added to the preset system scanning result list, and the corresponding relationship between the system part numbers corresponding to all the automobile systems can be obtained through the preset system scanning result list, so as to position all the automobile systems in the automobile.
