Description

Technical Field

[0001] The embodiments of the present invention relate to the field of automobile diagnosis technology, and in particular to a vehicle diagnostic data acquisition method, diagnostic equipment, communication equipment, vehicle diagnostic data acquisition system and storage medium. Background Art

[0002] With the development of society and the advancement of science and technology, the design and production of automobiles have increasingly adopted Electronic Control Units (ECU). On the one hand, this has made the degree of automation of automobiles higher and higher, the performance has become more superior, and the operation has become more convenient and flexible. On the other hand, it has also put forward higher requirements for automobile maintenance.

[0003] In automobile diagnosis, maintenance personnel or users can operate automobile diagnostic equipment, connect VCI (Vehicle Communication Interface, VCI) communication equipment, and obtain bus data through OBD (On-Board Diagnostics) interface to realize automobile diagnosis in certain scenarios (such as battery pack diagnosis of new energy vehicles). Due to the differences in design of automobiles of different brands and models, automobile ECU uses different pin pairs of OBD interface to send diagnostic data to the communication bus, resulting in diagnostic data distributed on one or more groups of pin pairs. Since the OBD interface has multiple groups of pin pairs, and diagnostic data may exist on each group of pin pairs, if it is not clear in advance which group of pin pairs is used to send diagnostic data, when obtaining diagnostic data on the communication bus through the diagnostic equipment, it is necessary to traverse all pin pairs in turn to obtain diagnostic data that may exist on all pin pairs. However, this communication process (i.e., obtaining data on each group of pin pairs in turn) has low communication efficiency. Maintenance personnel or users need to wait for each group of pin pairs to obtain possible data before the diagnostic equipment can perform subsequent processing. The data acquisition efficiency is low, which leads to reduced diagnostic efficiency and poor user experience. Summary of the invention

[0004] In view of this, one of the purposes of an embodiment of the present invention is to provide a vehicle diagnostic data acquisition method, a diagnostic device, a communication device, a vehicle diagnostic data acquisition system and a storage medium. After the communication device acquires the diagnostic data of at least two groups of target pin pairs, the method concurrently transmits the diagnostic data through at least two types of communication modules of the diagnostic device and the communication device, so that the diagnostic device can concurrently acquire the vehicle's diagnostic data, thereby improving data acquisition efficiency, reducing waiting time and improving user experience.

[0057] In some embodiments, the communication device 20 may be a VCI device, which is an electronic device with computing and processing capabilities, and is integrated with a communication interface, such as an OBD interface. The communication device 20 may be connected to the OBD interface of the vehicle 30 through the OBD interface, and the communication device 20 may convert the data on the bus of the vehicle 30 into data that can be recognized by the diagnostic device 10, and may also convert the data sent by the diagnostic device 10 into data that can be recognized by the bus of the vehicle 30.

[0084] In an embodiment of the present invention, the pin communication parameter includes a first identification code of a target pin pair and a first communication mode parameter corresponding to the first identification code, the first communication mode parameter includes a second identification code of a first communication module and a second identification code of a second communication module, and the diagnostic data and the communication device can transmit the diagnostic data of the target pin pair through the first communication module and the second communication module according to the first communication mode parameter. The number of target pin pairs includes at least two groups. Among them, the target pin pair is the pin pair of the communication interface in the communication device that the communication device needs to read.

[0085] Specifically, the diagnostic device selects a suitable communication protocol (e.g., CAN, LIN, etc.) to send pin communication parameters to the communication device based on the established communication connection (e.g., Bluetooth connection, Wi-Fi connection, or other connection, etc.), so that after receiving the pin communication parameters, the communication device obtains the diagnostic data on the target pin pair and sends the diagnostic data to the diagnostic device.

[0086] In some embodiments, before sending pin communication parameters to the communication device, the diagnostic device needs to first determine the target pin pair (i.e., which pin pairs in the communication interface of the communication device to obtain diagnostic data on), so as to match the corresponding type of communication module in the diagnostic device and the communication device according to the target pin pair to obtain the pin communication parameters.

[0087] Exemplarily, in some embodiments, before sending the pin communication parameters to the communication device, the vehicle diagnostic data acquisition method further includes but is not limited to the following steps S101-S103:

[0088] S101: Determine a target pin pair.

[0089] Specifically, the diagnostic device identifies the type of vehicle system and electronic control unit (ECU) through the vehicle model and technical documents provided by the manufacturer, and queries an internal or external database based on the identified vehicle system, and performs pin pair mapping based on the pin pair information in the database to determine the pin pair used for the diagnostic task and the corresponding pin pair configuration information (for example, information such as the function of the pin pair and the first identification code of the pin pair).

[0090] In some embodiments, the target pin pair can be selected and determined according to a preset rule. For example, the electronic control unit (ECU) of a certain vehicle type usually sends diagnostic data to the communication device's pin pairs 3 and 13, 4 and 12, and 5 and 11. Therefore, the model of the vehicle type and the pin pairs 3-13, 4-12, and 5-11 can be used to form a preset rule. When the diagnostic device identifies and detects that the vehicle is of this model, it can determine that the target pin pairs are pin pairs 3-13, 4-12, and 5-11 according to the preset rule.

[0091] Of course, there may be other suitable ways to determine the target pin pair, and those skilled in the art may determine the target pin pair in any suitable way, which is not limited in any way in the embodiment of the present invention.

[0092] S102: Determine a first communication mode parameter corresponding to a first identification code of a target pin pair based on the number of types of the first communication module or the second communication module and the number of target pin pairs, wherein the first communication mode parameter includes a second identification code of the first communication module and a second communication module.

[0093] Specifically, after determining the target pin pair of the communication device, the diagnostic device identifies the number of types of the second communication module currently configured by itself, that is, how many types of second communication modules are configured by itself. Or it identifies the number of types of the first communication module currently configured by the communication device, that is, how many types of first communication modules are configured by the communication device. It can be understood that since each type of first communication module corresponds to one type of second communication module, the number of types of the first communication module configured in the communication device is equal to the number of types of the second communication module configured in the diagnostic device.

[0094] The diagnostic device allocates a corresponding type of first communication module and second communication module to each target pin pair according to the number of types of first communication modules or second communication modules and the number of target pin pairs based on a predefined mapping rule, and uses the second identification code of the first communication module and the second identification code of the second communication module as the first communication mode parameters, thereby obtaining the first communication mode parameters corresponding to the first identification code of each target pin pair.

[0095] In some embodiments, the corresponding first communication module and second communication module can be allocated to the target pin pair according to the relationship between the number of types of first communication modules or second communication modules and the number of target pin pairs to obtain the first communication mode parameter corresponding to the first identification code of the target pin pair.

[0096] In some embodiments, based on the number of types of the first communication module or the second communication module and the number of target pin pairs, determining the first communication mode parameter corresponding to the first identification code of the target pin pair specifically includes but is not limited to the following steps S1021:

[0097] S1021: If the number of types of the first communication module or the second communication module is greater than or equal to the number of target pin pairs, a type of first communication module and a second communication module are respectively assigned to each group of target pin pairs, and the second identification code of the first communication module and the second communication module assigned to each target pin pair is used as the first communication mode parameter corresponding to the first identification code of each group of target pin pairs, wherein each group of target pin pairs corresponds to a type of first communication module and a second communication module.

[0098] Specifically, the number of types of the first communication module or the second communication module is compared with the number of target pin pairs. If the number of types of the first communication module or the second communication module is greater than or equal to the number of target pin pairs, it means that different types of first communication modules and second communication modules can be assigned to each group of target pin pairs. Then, a type of first communication module and second communication module is assigned to each group of target pin pairs, and the second identification code of the first communication module and the second identification code of the second communication module assigned to each group of target pin pairs are used as the first communication mode parameter corresponding to the first identification code of the group of target pin pairs. In this embodiment, each group of target pin pairs uniquely corresponds to a type of first communication module and second communication module, that is, the types of the first communication module and the second communication module corresponding to each group of target pin pairs are different.

[0099] For example, the target pin pairs include three groups, namely target pin pairs 1, 2 and 3, the first identification code of target pin pair 1 is A211, the first identification code of target pin pair 2 is B233, and the first identification code of target pin pair 3 is C257. The first communication module and the second communication module include four types, namely Wi-Fi module, Bluetooth module, NFC module and Zigbee module.

[0100] Among the four types of first communication modules and second communication modules, different types of first communication modules and second communication modules are respectively allocated to three groups of target pin pairs. For example, the first communication module and the second communication module of the type of Wi-Fi module are allocated to the target pin pair 1, and the second identification code of the first communication module (i.e., Wi-Fi module) and the second identification code of the second communication module (i.e., Wi-Fi module) are used as the first communication mode parameter corresponding to the first identification code of the group of target pin pairs. The first communication module and the second communication module of the type of NFC module are allocated to the target pin pair 2, and the second identification code of the first communication module (i.e., NFC module) and the second identification code of the second communication module (i.e., NFC module) are used as the first communication mode parameter corresponding to the first identification code of the group of target pin pairs. The first communication module and the second communication module of the type of Bluetooth module are allocated to the target pin pair 3, and the second identification code of the first communication module (i.e., Bluetooth module) and the second identification code of the second communication module (i.e., Bluetooth module) are used as the first communication mode parameter corresponding to the first identification code of the group of target pin pairs.

[0101] Exemplarily, in some other embodiments, based on the number of types of the first communication module or the second communication module and the number of target pin pairs, determining the first communication mode parameter corresponding to the first identification code of the target pin pair specifically includes but is not limited to the following steps S1022-S1024:

[0102] S1022: If the number of types of the first communication module or the second communication module is less than the number of target pin pairs, at least two types of first communication modules and second communication modules are respectively assigned to a first number of target pin pairs, and the target pin pairs to which the first communication modules and the second communication modules are not assigned are counted, where the first number is the number of types of the first communication module or the second communication module.

[0103] Specifically, when comparing the number of types of the first communication module or the second communication module and the number of target pin pairs, if the number of types of the first communication module or the second communication module is less than the number of target pin pairs, it means that different types of first communication modules and second communication modules cannot be assigned to each group of target pin pairs, that is, different target pin pairs need to be assigned the same type of first communication modules and second communication modules, then at least two types of first communication modules and second communication modules are respectively assigned to a first number of target pin pairs, the first number being the number of types of the first communication module or the second communication module, so as to ensure that each type of first communication module and second communication module is assigned to the corresponding target pin pair. Then, the target pin pairs to which the first communication module and the second communication module have not yet been assigned are counted.

[0104] S1023: Filter out one or more types of reference communication modules whose data transmission rates are greater than or equal to a rate threshold from among the first communication modules and the second communication modules of various types, and assign reference communication modules to target pin pairs to which the first communication modules and the second communication modules are not assigned, wherein each type of the first communication modules and the second communication modules corresponds to one or more groups of target pin pairs.

[0105] Specifically, among at least two types of first communication modules and second communication modules, one or more types of first communication modules and second communication modules whose data transmission rates are greater than or equal to a rate threshold are screened out according to the data transmission rates of the first communication modules and the second communication modules, and the first communication modules and second communication modules whose data transmission rates are greater than or equal to the rate threshold are marked as reference communication modules.

[0106] Then, a reference communication module is allocated to the target pin pairs that have not yet been allocated the first communication module and the second communication module according to the types and availability of the first communication module and the second communication module. In this embodiment, each type of the first communication module and the second communication module corresponds to one or more groups of target pin pairs, that is, each type of the first communication module and the second communication module is used to transmit diagnostic data of one or more groups of target pin pairs, and the types of the first communication modules and the second communication modules corresponding to different target pin pairs may be the same or different.

[0107] S1024: Using the second identification code of the first communication module and the second communication module assigned to each target pin pair as the first communication mode parameter corresponding to the first identification code of each group of target pin pairs to obtain the first communication mode parameter.

[0108] After assigning the corresponding first communication module and second communication module to each group of target pin pairs, the second identification code of the first communication module and the second identification code of the second communication module assigned to each group of target pin pairs are used as the first communication mode parameters corresponding to the first identification code of the group of target pin pairs, thereby obtaining the first communication mode parameters corresponding to the first identification code of each group of target pin pairs.

[0109] For example, the target pin pairs include three groups, namely, target pin pairs 4, 5 and 6, the first identification code of target pin pair 4 is A121, the first identification code of target pin pair 5 is B143, and the first identification code of target pin pair 6 is C177. The first communication module and the second communication module include two types, namely, a Wi-Fi module and a Bluetooth module, wherein the data transmission rate of the first communication module of the Wi-Fi module type and the second communication module is greater than the rate threshold.

[0110] In this embodiment, if the number of target pin pairs is greater than the number of types of the first communication module or the second communication module, the first communication module and the second communication module of the type of Wi-Fi module are assigned to target pin pair 4, and the first communication module and the second communication module of the type of Bluetooth module are assigned to target pin pair 5, and the target pin pair 6 remains without the first communication module and the second communication module.

[0111] Among the two types of first communication modules and second communication modules, a reference communication module whose data transmission rate is greater than or equal to the rate threshold is screened out, that is, the first communication module and the second communication module of the type of Wi-Fi module, and the first communication module and the second communication module of the type of Wi-Fi module are assigned to the target pin pair 6.

[0112] Then, the second identification code of the first communication module and the second communication module of the type of Wi-Fi module assigned to the target pin pair 4 is used as the first communication mode parameter corresponding to the first identification code of the target pin pair 4. The second identification code of the first communication module and the second communication module of the type of Bluetooth module assigned to the target pin pair 5 is used as the first communication mode parameter corresponding to the first identification code of the target pin pair 5. The second identification code of the first communication module and the second communication module of the type of Wi-Fi module assigned to the target pin pair 6 is used as the first communication mode parameter corresponding to the first identification code of the target pin pair 6, thereby obtaining the first communication mode parameter corresponding to the first identification code of each group of target pin pairs.

[0113] In some embodiments, the first communication module of the communication device is any one of a Wi-Fi module, a USB module, a Bluetooth module and an Ethernet module, and correspondingly, the second communication module of the diagnostic device is any one of a Wi-Fi module, a USB module, a Bluetooth module and an Ethernet module.

[0114] S103: Combine the first identification code of the target pin pair and the first communication mode parameter corresponding to the first identification code to obtain a pin communication parameter.

[0115] Specifically, after determining the first communication mode parameter corresponding to the first identification code of the target pin pair, the diagnostic device combines the first identification code of the target pin pair and the first communication mode parameter corresponding to the first identification code of the target pin pair, that is, combines the first identification code of the target pin pair and the second identification code of the first communication module and the second identification code of the second communication module corresponding to the first identification code of the target pin pair to obtain the pin communication parameters.

[0116] For example, the target pin pairs include three groups, namely target pin pairs A, B and C, the first identification code of target pin pair A is A206, the first identification code of target pin pair B is B204, and the first identification code of target pin pair C is C207. Among them, the types of the first communication module and the second communication module assigned to the target pin pair A are Wi-Fi modules, the second identification code of the first communication module is Wi-Fi-11, and the second identification code of the second communication module is Wi-Fi-21, then the first communication mode parameter corresponding to the first identification code A206 of the target pin pair A includes the second identification code Wi-Fi-11 of the first communication module and the second identification code Wi-Fi-21 of the second communication module.

[0117] The types of the first communication module and the second communication module assigned to the target pin pair B are Bluetooth modules, the second identification code of the first communication module is Bluetooth-101, and the second identification code of the second communication module is Bluetooth-201. The first communication mode parameters corresponding to the first identification code B204 of the target pin pair B include the second identification code Bluetooth-101 of the first communication module and the second identification code Bluetooth-201 of the second communication module.

[0118] The types of the first communication module and the second communication module assigned to the target pin pair C are NFC modules, the second identification code of the first communication module is NFC-11, and the second identification code of the second communication module is NFC-21. The first communication mode parameters corresponding to the first identification code C207 of the target pin pair C include the second identification code NFC-11 of the first communication module and the second identification code NFC-21 of the second communication module.

[0119] Then, the first identification codes of the target pin pairs A, B and C and the second identification codes of the first communication module and the second identification codes of the second communication module corresponding to the first identification codes of the target pin pairs A, B and C are combined together to obtain pin communication parameters. In this embodiment, the pin communication parameters include three groups of parameters, namely [A206, Wi-Fi-11, Wi-Fi-21], [B204, Bluetooth-101, Bluetooth-201] and [C207, NFC-11, NFC-21].

[0120] S200: receiving diagnostic data of the target pin pair through the second communication module corresponding to the first communication mode parameter, wherein after acquiring the diagnostic data on the target pin pair, the communication device sends the diagnostic data of the target pin pair to the diagnostic device through the first communication module corresponding to the first communication mode parameter.

[0121] Specifically, the diagnostic device configures the corresponding second communication module according to the first communication mode parameter to ensure that the diagnostic data sent by the communication device can be received. The second communication module starts the monitoring process under the specified communication protocol and prepares to receive the diagnostic data. It can be understood that after receiving the pin communication parameters sent by the diagnostic device and obtaining the diagnostic data on the target pin pair according to the pin communication parameters, the communication device sends the diagnostic data to the diagnostic device through the first communication module corresponding to the first communication mode parameter, so that the diagnostic device receives the diagnostic data of the target pin pair.

[0122] In some embodiments, after receiving the diagnostic data through the second communication module, the diagnostic device parses the diagnostic data, extracts the diagnostic data and the first identification code, and then further processes, analyzes or displays the diagnostic data to obtain subsequent fault diagnosis results.

[0123] In some embodiments, the diagnostic device further includes a cache module, and after receiving the diagnostic data, the diagnostic device stores the diagnostic data in the cache module.

[0124] Specifically, in some embodiments, the vehicle diagnostic data acquisition method further includes but is not limited to the following steps S201:

[0125] S201: Storing diagnostic data of a target pin pair into a cache module, and recording a first identification code corresponding to the diagnostic data.

[0126] Specifically, after receiving the diagnostic data through the second communication module corresponding to the first communication mode parameter, the diagnostic device stores the received diagnostic data in the cache module of the diagnostic device, parses the received diagnostic data, extracts the first identification code corresponding to the diagnostic data (that is, the first identification code unique to the target pin pair, used to indicate that the diagnostic data originates from the group of target pin pairs), and records the first identification code corresponding to the extracted diagnostic data.

[0127] In some embodiments, in the cache module, the diagnostic data and the first identification code corresponding to the diagnostic data are associated and stored, so that the diagnostic data related to the specific pin pair can be quickly retrieved during subsequent query and processing.

[0128] In some embodiments, the diagnostic device monitors the amount of diagnostic data in the cache module in real time to determine whether a required amount of diagnostic data has been received.

[0129] Specifically, in some embodiments, the vehicle diagnostic data acquisition method further includes but is not limited to the following steps S202-S203:

[0130] S202: If the amount of diagnostic data corresponding to the first identification code is greater than or equal to a preset amount threshold, output the diagnostic data corresponding to the first identification code in the cache module to a diagnostic application of the diagnostic device.

[0131] Specifically, in the process of receiving diagnostic data, the diagnostic device monitors the number of diagnostic data corresponding to the first identification code in the cache module in real time. When the number of diagnostic data corresponding to the first identification code reaches or exceeds the preset number threshold (i.e., greater than or equal to the preset number threshold), it means that a sufficient number of diagnostic data has been received, triggering the diagnostic data output condition. The diagnostic data corresponding to the first identification code is retrieved in the cache module, and the diagnostic data corresponding to the first identification code is packaged or organized into a suitable data format, and then the packaged or organized diagnostic data is sent to the diagnostic application of the diagnostic device through a suitable communication channel (e.g., TCP / IP, Bluetooth, CAN bus, etc.), so that the diagnostic application processes and analyzes the diagnostic data, troubleshoots the fault, or displays it to the user after receiving the diagnostic data.

[0132] In some embodiments, after the diagnostic data corresponding to the first identification code is sent to the diagnostic application, the diagnostic data corresponding to the first identification code in the cache module may be deleted to release the storage space of the cache module.

[0133] S203: If the amount of diagnostic data corresponding to the first identification code is less than a preset amount threshold, and the duration of the target pin pair corresponding to the first identification code obtaining diagnostic data is greater than or equal to a preset time threshold, then the diagnostic data corresponding to the first identification code in the cache module is output to the diagnostic application of the diagnostic device.

[0134] Specifically, if the number of diagnostic data corresponding to the first identification code does not reach a preset number threshold (i.e., less than a preset number threshold), and the duration of the target pin pair corresponding to the first identification code obtaining diagnostic data is greater than or equal to a preset time threshold, it also indicates that a sufficient amount of diagnostic data has been received, triggering the diagnostic data output condition. The diagnostic data corresponding to the first identification code is retrieved in the cache module, the diagnostic data corresponding to the first identification code is packaged or organized into a suitable data format, and then the packaged or organized diagnostic data is sent to the diagnostic application of the diagnostic device through a suitable communication channel (e.g., TCP / IP, Bluetooth, and CAN bus, etc.), so that the diagnostic application processes and analyzes the diagnostic data, troubleshoots, or displays it to the user after receiving the diagnostic data.

[0135] It is easy to understand that for the preset quantity threshold and the preset time threshold, those skilled in the art can set and determine them according to actual application scenarios and historical experience data. For example, the preset quantity threshold can be 10, and the preset time threshold can be 30 seconds. The embodiments of the present invention do not impose any limitations on this.

[0136] In summary, the vehicle diagnostic data acquisition method provided in the embodiment of the present invention is applied to a diagnostic device, the diagnostic device is connected to a communication device, the communication device includes a communication interface and at least two types of first communication modules, the diagnostic device includes at least two types of second communication modules, each type of first communication module corresponds to one type of second communication module, the communication device is connected to the electronic control unit of the vehicle through the communication interface, the communication interface has multiple groups of pin pairs, and the electronic control unit sends diagnostic data to the pin pairs of the communication interface; the method includes: sending pin communication parameters to the communication device, the pin communication parameters include a first identification code of the target pin pair and a first communication mode parameter corresponding to the first identification code, and the number of target pin pairs includes at least two groups; receiving the diagnostic data of the target pin pair through the second communication module corresponding to the first communication mode parameter, wherein, after obtaining the diagnostic data on the target pin pair, the communication device sends the diagnostic data of the target pin pair to the diagnostic device through the first communication module corresponding to the first communication mode parameter.

[0137] The vehicle diagnostic data acquisition method provided in the embodiment of the present invention concurrently transmits the diagnostic data through at least two types of communication modules of the diagnostic device and the communication device after the communication device acquires the diagnostic data of at least two groups of target pin pairs, so that the diagnostic device can concurrently acquire the vehicle's diagnostic data, thereby improving data acquisition efficiency, reducing waiting time, and improving user experience.

[0138] Next, the vehicle diagnostic data acquisition method provided by the second aspect of the embodiment of the present invention is explained in detail.

[0139] See also Figure 6 , Figure 6 The flowchart of the vehicle diagnostic data acquisition method provided by some embodiments of the present invention is schematically shown.

[0140] Those skilled in the art will appreciate that the vehicle diagnostic data acquisition method provided in the embodiment of the present invention can be applied to the above communication device (eg, communication device 20). Specifically, the vehicle diagnostic data acquisition method is executed by one or at least two second processors of the communication device.

[0141] like Figure 6 As shown, the vehicle diagnostic data acquisition method includes but is not limited to the following steps S300-S500:

[0142] S300: receiving pin communication parameters sent by a diagnostic device, wherein the pin communication parameters include a first identification code of a target pin pair and a first communication mode parameter corresponding to the first identification code, and the number of the target pin pairs includes at least two groups.

[0143] In an embodiment of the present invention, the pin communication parameter includes a first identification code of a target pin pair and a first communication mode parameter corresponding to the first identification code, the first communication mode parameter includes a second identification code of a first communication module and a second identification code of a second communication module, and the diagnostic data and the communication device can transmit the diagnostic data of the target pin pair through the first communication module and the second communication module according to the first communication mode parameter. The number of target pin pairs includes at least two groups. Among them, the target pin pair is the pin pair of the communication interface in the communication device that the communication device needs to read.

[0144] Specifically, the communication device receives the pin communication parameters sent by the diagnostic device through the communication protocol (eg, CAN, LIN, etc.) selected by the diagnostic device based on the established communication connection (eg, Bluetooth connection, Wi-Fi connection, or other connection, etc.).

[0145] S400: Acquire diagnostic data from the target pin pair.

[0146] Specifically, after receiving the pin communication parameters, the communication device parses the received pin communication parameters and extracts the contents of the pin communication parameters, namely, obtains the first identification code of the target pin pair and the first communication mode parameter corresponding to the first identification code of the target pin pair.

[0147] The communication device obtains the diagnostic data sent by the vehicle to the target pin pair from the target pin pair in its own communication interface according to the first identification code of the target pin pair in the pin communication parameter. It is understandable that the electronic control unit of the vehicle can actively or passively send diagnostic data to the pin pair in the communication interface of the communication device. In some embodiments, after receiving the diagnostic data, the communication device parses the received diagnostic data, extracts useful data information, and performs necessary processing or format conversion so as to subsequently send it to the diagnostic device.

[0148] S500: After acquiring the diagnostic data on the target pin pair, sending the diagnostic data of the target pin pair to the diagnostic device through the first communication module corresponding to the first communication mode parameter, wherein the diagnostic device receives the diagnostic data of the target pin pair through the second communication module corresponding to the first communication mode parameter.

[0149] Specifically, after obtaining the diagnostic data on the target pin pair, the communication device determines to use the first communication module that sends the diagnostic data according to the first communication mode parameter. The communication device sends the diagnostic data of the target pin pair to the diagnostic device through the selected first communication module. Since each type of second communication module in the diagnostic device corresponds to a type of first communication module in the communication device (i.e., the second identification code of the first communication module in the first communication mode parameter corresponds one to one with the second identification code of the second communication module), after the communication device sends the diagnostic data of the target pin pair, the diagnostic device receives the diagnostic data of the target pin pair through the second communication module corresponding to the first communication mode parameter.

[0150] In some embodiments, after obtaining the diagnostic data of the target pin pair, the first identification code of the target pin pair is added to the diagnostic data of the target pin pair so that the diagnostic device can record the amount of received diagnostic data according to the first identification code of the target pin pair.

[0151] Specifically, in some embodiments, before sending the diagnostic data of the target pin pair to the diagnostic device through the first communication module corresponding to the first communication mode parameter, the vehicle diagnostic data acquisition method further includes but is not limited to the following steps S501:

[0152] S501: After obtaining the diagnostic data of the target pin pair, add the first identification code of the target pin pair to the diagnostic data of the target pin pair, wherein each group of target pin pairs corresponds to a unique first identification code, and the first identification code represents the target pin pair used to obtain the diagnostic data in the communication interface of the communication device.

[0153] Among them, each group of target pin pairs in the pin communication parameters corresponds to a unique first identification code, and the first identification code represents the target pin pair used to obtain diagnostic data in the communication interface of the communication device. The target pin pair is the pin pair for the vehicle's electronic control unit to send diagnostic data.

[0154] Specifically, after obtaining the diagnostic data of the target pin pair and before sending the diagnostic data of the target pin pair to the diagnostic device, the communication device adds the first identification code of the target pin pair to the diagnostic data of the corresponding target pin pair as auxiliary information of the diagnostic data (for example, the first identification code can be used as meta-information of the diagnostic data) to indicate which specific pin pair the group of diagnostic data comes from. Then, the complete data packet containing the diagnostic data and the first identification code is packaged into a suitable data format so as to be sent to the diagnostic device through the corresponding first communication module.

[0155] Through the above method, it is ensured that the diagnostic data has a clear source identification during the transmission process, which is conducive to the diagnostic device to correctly parse and process the diagnostic data when it is received.

[0156] In summary, the vehicle diagnostic data acquisition method provided by the embodiment of the present invention is applied to a communication device, the communication device is connected to the diagnostic device, the communication device includes a communication interface and at least two types of first communication modules, the diagnostic device includes at least two types of second communication modules, each type of first communication module corresponds to one type of second communication module, the communication device is connected to the electronic control unit of the vehicle through the communication interface, the communication interface has multiple groups of pin pairs, and the electronic control unit sends diagnostic data to the pin pairs of the communication interface; the method includes: receiving pin communication parameters sent by the diagnostic device, the pin communication parameters include a first identification code of the target pin pair and a first communication mode parameter corresponding to the first identification code; acquiring diagnostic data from the target pin pair; after acquiring the diagnostic data on the target pin pair, sending the diagnostic data of the target pin pair to the diagnostic device through the first communication module corresponding to the first communication mode parameter, and the diagnostic device receives the diagnostic data of the target pin pair through the second communication module corresponding to the first communication mode parameter.

[0157] The vehicle diagnostic data acquisition method provided in the embodiment of the present invention concurrently transmits the diagnostic data through at least two types of communication modules of the communication device and the diagnostic device after the communication device acquires the diagnostic data of at least two groups of target pin pairs, so that the diagnostic device can concurrently acquire the vehicle's diagnostic data, thereby improving data acquisition efficiency, reducing waiting time, and improving user experience.

[0158] An embodiment of the present invention provides a computer-readable storage medium, on which computer program instructions executable by a processor are stored. When the computer program instructions are called by the processor, the processor executes any one of the vehicle diagnostic data acquisition methods provided by the embodiments of the present invention, or executes the steps in any one of the implementation methods of any one of the vehicle diagnostic data acquisition methods provided by the embodiments of the present invention.

[0159] In some embodiments, the storage medium may be a flash memory, a hard disk, an optical disk, a register, a magnetic surface storage, a removable disk, a CD-ROM, a random access memory (RAM), a read-only memory (ROM), an electrically programmable ROM, and an electrically erasable programmable ROM, or any other form of storage medium known in the technical field, or various devices including one or any combination of the above storage media.

[0160] In some embodiments, computer program instructions may be in the form of a program, software, software module, script or code, written in any form of programming language (including compiled or interpreted languages, or declarative or procedural languages), and may be deployed in any form, including as a stand-alone program or as a module, component, subroutine or other unit suitable for use in a computing environment.

[0161] As an example, computer program instructions may, but do not necessarily, correspond to a file in a file system, may be stored as part of a file that stores other programs or data, for example, in one or more scripts in a HyperText Markup Language (HTML) document, in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files storing one or more modules, subroutines, or code portions).
