[0038] At present, intelligent driving adopts the method of building scenes when conducting simulation.

After calculation, the intelligent driving controller outputs the relevant signal to the simulation model to form a signal closed loop, and judges whether the software function is realized according to the relevant input and output rules to complete the simulation verification of the software. However, the number of simulated signal interactions is tens of thousands, which is extremely large, resulting in inefficiency, long time and high matching error rate in matching input simulation signals, which seriously affects the efficiency and accuracy of simulation verification.

[0039] In a first aspect, the present invention provides Figure 1 The method for automatically matching intelligent driving simulation signals shown in the figure comprises the following steps:

[0040] S1, obtaining virtual domain controller signal data and simulation signal data;

[0041] The acquired virtual domain controller signal data is stored in a virtual domain controller signal list in the form of a list, and the acquired simulation signal data is stored in a simulation signal list in the form of a list, wherein the virtual domain controller signal data includes a plurality of virtual domain controller signals, and each row or column in the virtual domain controller signal list represents identification information of one of the virtual domain controller signals, wherein the identification information of the virtual domain controller signal includes at least a signal address; the simulation signal data includes a plurality of simulation signals, and each row or column in the simulation signal list represents identification information of one of the simulation signals, wherein the identification information of the simulation signal includes at least a signal address.

[0042] In one embodiment, the virtual domain controller signal data includes several virtual domain controller signals, each row in the virtual domain controller signal list represents one of the virtual domain controller signals, and each column in the virtual domain controller signal list represents identification information of the virtual domain controller signal, wherein the identification information of the virtual domain controller signal includes at least a signal address; the simulation signal data includes several simulation signals, each row in the simulation signal list represents one of the simulation signals, and each column in the simulation signal list represents identification information of a simulation signal, wherein the identification information of the simulation signal includes at least a signal address.

[0043] The virtual domain controller signal has at least one identification information. Specifically, the identification information of the virtual domain controller signal may be a signal name and a signal address, or the identification information of the virtual domain controller signal may be a signal address and a serial port name, or the identification information of the virtual domain controller signal may be a signal name, a signal address and a serial port name.

[0044] In one embodiment, the identification information of the virtual domain controller signal includes a signal name, a signal address, and a serial port name. The number of specific identification information of the virtual domain controller signal can be defined according to actual conditions, and the identification information of the virtual domain controller signal is stored in the form of a string. The identification information of the simulation signal includes a signal name, a signal address, and a serial port name. The number of specific identification information of the simulation signal can be defined according to actual conditions, and the identification information of the simulation signal is stored in the form of a string.

[0046] S2, processing the virtual domain controller signal data to obtain virtual domain controller character data in the form of key-value pairs; processing the simulation signal data to obtain simulation character data in the form of key-value pairs;

[0047] The virtual domain controller character data in the form of key-value pairs obtained by processing the virtual domain controller signal data includes:

[0048] Define at least one class; sequentially assign the signal identification information in the virtual domain controller signal list to an object of a class, segment and splice the signal address of the virtual domain controller signal as the key of the virtual domain controller signal, and use the object of the class as the value of the virtual domain controller signal. In one embodiment, sequentially represents one by one according to the arrangement order of the virtual domain controller signal list, and assigns each identification information of the virtual domain controller signal to an object of a class. The number of objects of a class is greater than or equal to the number of identification information of a virtual domain controller signal. In one embodiment, the number of objects of a class is 3, the number of identification information of the virtual domain controller signal is 3, and the 3 identification information of the virtual domain controller signal is assigned to the 3 objects of the class. In another embodiment, the number of objects of a class is 4, the number of identification information of the virtual domain controller signal is 3, and the 3 identification information of the sensor signal is assigned to the first 3 objects of the class, and the 4th object of the class is empty and not assigned.

[0049] Define several dictionaries A, and put a key-value pair obtained by processing each virtual domain controller signal into dictionary A.

[0050] The class in this embodiment is a template for creating an object, which defines a set of properties and methods. A dictionary is a data type, and each element in the dictionary is a key-value pair, that is, a set of corresponding keys and values, where the key must be unique and is used as a retrieval tag, and the value is used to store information. Although the class in this embodiment is based on object-oriented programming languages, such as python, C++, etc., the functions similar to the class in this embodiment can also be realized by programming based on process-oriented programming languages ​​such as C language, and the present disclosure does not specifically limit the programming language. The present disclosure uses the uniqueness of the key to assign each identification information in the virtual domain controller signal to an object of the class, and divides and splices the virtual domain controller address in the identification information. The virtual domain controller address is a string, in which the virtual domain controller address of each virtual domain controller signal contains the same characters, removes these same characters and splices the remaining characters into a string as a key, and the remaining class objects are used as corresponding values. Each virtual domain controller signal in the virtual domain controller signal list is converted into a key-value pair in the dictionary and stored in dictionary A in turn.

[0051] The steps of converting the simulated signal data into simulated character data in the form of key-value pairs after segmentation and splicing include:

[0052] Define at least one class; assign the signal identification information in the simulation signal list to an object of a class in sequence, segment and concatenate the signal address of the simulation signal as the key of the simulation signal, and use the object of the class as the value of the simulation signal. In one embodiment, sequentially represents one by one according to the arrangement order of the simulation signal list, and assigns each identification information of the simulation signal to an object of a class. The number of objects of a class is greater than or equal to the number of identification information of a simulation signal. In one embodiment, the number of objects of a class is 3, the number of identification information of the simulation signal is 3, and the 3 identification information of the simulation signal is assigned to the 3 objects of the class. In another embodiment, the number of objects of a class is 4, the number of identification information of the simulation signal is 3, and the 3 identification information of the sensor signal is assigned to the first 3 objects of the class, and the 4th object of the class is empty and not assigned.

[0053] At least one dictionary B is defined, and the key and value of the simulation signal are stored in the dictionary B as a key-value pair.

[0054] The present disclosure uses the uniqueness of the key to assign each identification information in the simulation signal to an object of the class, and divides and splices the simulation address in the identification information. The simulation address is a string, which has the same characters contained in the simulation address of each simulation signal. These same characters are removed and the remaining characters are spliced ​​into a string as the key, and the remaining class objects are used as corresponding values. Each simulation signal in the simulation signal list is converted into a key-value pair in the dictionary and stored in the dictionary B in turn.

[0055] S3. Match the virtual domain controller character data with the simulation character data one by one to obtain a matching list and a prompt list.

[0056] The steps of matching the virtual domain controller character data with the simulation character data one by one include:

[0057] The keys in the virtual domain controller character data are matched one by one with the keys in the simulation character data. If the keys in the virtual domain controller character data are the same as the keys in the simulation character data, the match is determined to be successful; if the keys in the virtual domain controller character data are not the same as the keys in the simulation character data, the match is determined to have failed.

[0058] In one embodiment, the keys in the virtual domain controller character data are looped in sequence and the same keys are searched in the simulation character data. If there is the same key in the simulation character data as in the virtual domain controller character data, the match is determined to be successful; if there is no same key in the simulation character data as in the virtual domain controller character data, the match is determined to be unsuccessful. If the match is determined to be successful, the values ​​corresponding to the key in the virtual domain controller character data and the simulation character data are placed in the same row in the match list; if the match is determined to be unsuccessful, the value corresponding to the key in the virtual domain controller character data is placed in the prompt list; finally, the value corresponding to the key in the simulation character data that has not been successfully matched is placed in the prompt list. Among them, looping in sequence represents that the arrangement order of the keys in the virtual domain controller character data is performed one by one.

[0059] In another embodiment, the keys in the simulation character data are looped in sequence and the same keys are searched in the virtual domain controller character data. If there is the same key in the virtual domain controller character data as in the simulation character data, the match is determined to be successful; if there is no same key in the virtual domain controller character data as in the simulation character data, the match is determined to be unsuccessful. If the match is determined to be successful, the values ​​corresponding to the key in the simulation character data and the virtual domain controller character data are placed in the same row in the matching list; if the match is determined to be unsuccessful, the values ​​corresponding to the key in the simulation character data are placed in the prompt list; finally, the values ​​corresponding to the keys that have not been successfully matched in the virtual domain controller character data are placed in the prompt list. Among them, looping in sequence represents the arrangement order of the keys in the virtual domain controller character data one by one. By utilizing the uniqueness of the keys in the virtual domain controller character data and the simulation character data, and the keys after cutting and splicing are shorter and more accurate, the virtual domain controller signal will not match the wrong simulation signal during matching, and the virtual domain controller signal and the simulation signal can complete the matching quickly and efficiently.

[0060] Second, as Figure 2 As shown, the present invention provides a simulation signal automatic matching device, including a signal acquisition module, a simulation signal module and a signal matching module, wherein the signal matching module is electrically connected to the signal acquisition module and the simulation signal module, the signal acquisition module is used to acquire virtual domain controller signals, the simulation signal module is used to generate simulation signals, and the signal matching module uses the described intelligent driving simulation signal automatic matching method to match the virtual domain controller signal with the simulation signal. In this embodiment, the signal acquisition module is used to acquire virtual domain controller signals of the automobile intelligent driving system, and the simulation signal module simulates the signals to be simulated according to the signal level and attribute requirements through MATLAB Simulink. The signal flows of the signal acquisition module and the simulation signal module are mutual, the signal acquisition module has a virtual domain controller signal flowing to the simulation signal module to obtain a simulation signal, and the simulation signal module also has a virtual domain controller signal flowing to the signal acquisition module to obtain a simulation signal. When the signal matching module matches the virtual domain controller signal collected by the signal acquisition module with the simulation signal generated by the simulation signal module, the key of the virtual domain controller character data obtained by the virtual domain controller signal as virtual domain controller signal data is consistent with the key of the virtual domain controller character data obtained by the simulation signal as virtual domain controller signal data; similarly, the key of the simulation character data obtained by the virtual domain controller signal as simulation signal data is consistent with the key of the simulation character data obtained by the simulation signal as simulation signal data.

[0061] The signal acquisition module converts the collected virtual domain controller signals into ARXML files, and the simulation signal module compiles the simulation signals into sic files. ARXML files are a common file format for automotive electronic systems and are easy to convert into lists. Sic files contain the implementation data of Simulink models, which can be used on computers without MATLAB and Simulink, and are easy to convert into lists.

[0062] Specifically, Figure 3 The following usage examples are provided in this embodiment:

[0063] The signal acquisition module collects the virtual domain controller signals in the intelligent driving system and converts them into ARXML files. The simulation signal module simulates the signals to be simulated according to the signal level and attribute requirements, compiles them into sic files in Simulink, and transfers the ARXML files and sic files to the signal matching module.

[0064] The signal matching module extracts the virtual domain controller signal in the ARXML file and the simulation signal in the sic file, and organizes and classifies them into a virtual domain controller signal list and a simulation signal list. Among them, the virtual domain controller signal data includes a number of virtual domain controller signals, each row in the virtual domain controller signal list represents a virtual domain controller signal, each column in the virtual domain controller signal list represents the identification information of the virtual domain controller signal, and the identification information of the virtual domain controller signal in this embodiment includes the signal name, signal address and serial port name, and the identification information of the virtual domain controller signal is stored in the form of a string; the simulation signal data includes a number of simulation signals, each row in the simulation signal list represents a simulation signal, each column in the simulation signal list represents the identification information of a simulation signal, and the identification information of the simulation signal in this embodiment includes the signal name, signal address and serial port name, and the identification information of the simulation signal is stored in the form of a string.
