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 only a part of the embodiments of the present invention, 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 invention.
Referring to fig. 1, it is a schematic flow chart of an automatic generation method of an I/O module model of a vehicle control unit software according to an embodiment of the present invention, and the method includes steps S10 to S15:
s10, acquiring each type of CAN message information in the DBC file and each type of CAN signal information corresponding to each type of CAN message information;
the controller of the entire vehicle collects the CAN message information (i.e., CAN messages, which carry information of each CAN signal) sent from each part of the entire vehicle, and stores the CAN message in the DBC file in the form of text, referring to fig. 2 to 3. Each CAN message may include its own CAN message information (e.g., CAN message address, CAN message transmission and reception type, etc.) and CAN signal information (e.g., CAN signal name, start bit, signal length, maximum value, minimum value, transmission and reception node, etc.). For example, each piece of CAN message information CAN correspond to information with five different CAN signals, namely signal1, signal2, signal3, signal4 and signal5, besides the own CAN message address.
Preferably, the step S10 specifically includes steps S100 to S101:
s100, extracting CAN message information and CAN signal information compiled by a preset compiling rule in a DBC file by using a regular expression;
referring to fig. 2 to 3, the CAN message information and the CAN signal information are compiled according to a predetermined compiling rule and stored in the DBC file. Specifically, the CAN message information is compiled according to the naming specification of the CAN message; the CAN signal information is compiled according to the naming specification of the CAN signal, the underscore _ "is used for distinguishing the meaning of each field in the signal name, and the identifier in the name is used for distinguishing the valid signal, the check signal, the invalid signal and the like in the CAN signal, for example, the check signal CAN be identified by _VD. It can be understood that the standardization of information compilation of the DBC file is a precondition for realizing the automatic generation of the I/O module model.
It should be noted that when the CAN signal information is compiled, a compilation specification of key information such as a signal length, a signal unit, a sending node and the like of the CAN signal CAN be defined, which is an auxiliary condition generated by a subsequent CAN signal classification and CAN signal classification processing module. Meanwhile, a check rule of the information content of the DBC file can be designed, such as maximum and minimum value accounting, effective value range accounting and the like, so that normal generation of a subsequent module is ensured.
In this step, the script in the MATLAB software is run, the program command written according to the present invention is executed, referring to fig. 4, the CAN message information and the CAN signal information in the DBC file of the communication matrix are automatically extracted by using the regular expression for the subsequent module to generate and use.
S101, identifying the type of each CAN message and the CAN signal information corresponding to each CAN message, and classifying the CAN signal information corresponding to each CAN message according to the signal type to obtain a CAN data structure SignalInfo; the CAN data structure SignalInfo comprises the classified CAN message information and each classified CAN signal information corresponding to each type of CAN message information.
When the CAN messages and the CAN signal information are obtained from the DBC file, the types of the CAN messages need to be identified, the CAN signal information corresponding to each CAN message information needs to be identified (that is, the inclusion relationship between the CAN signal information and the corresponding CAN message information needs to be identified), and then the CAN signal information corresponding to each CAN message needs to be classified according to the signal types. After the category of each CAN message information and the category of each CAN signal information corresponding to each CAN message information are identified, the data structure SignalsInfo is generated, see fig. 5, so as to obtain the classification result of the information.
It should be noted that, when the CAN signal information is classified, the invalid CAN signal information does not need to participate in the classification, that is: the CAN data structure SignalsInfo does not contain invalid CAN signal information.
S11, generating a corresponding CAN message processing module according to the type of the CAN message information to obtain a frame of an I/O module model;
specifically, referring to fig. 8, each of the CAN message messages may generate corresponding CAN message processing modules according to its own category (for example, according to the classification of the CAN message addresses or according to the classification of the CAN transceiving types), where the CAN message processing modules are frames of I/O modules of the vehicle controller software, and are connected to other modules of the application software of the vehicle controller to obtain CAN messages sent by the other modules.
S12, generating a corresponding CAN signal classification processing module in the corresponding CAN message processing module according to the classification result of the CAN signal information corresponding to each CAN message information;
preferably, the CAN signal information corresponding to each CAN message information is divided into three data types, namely Float, UInt and boot, for processing according to the signal length and the physical meaning of the CAN signal, so as to maintain the consistency of the signals of the same data type in the processing mode and facilitate the simplification of the module. For example, referring to fig. 9, if a CAN message corresponds to information of five different CAN signals, namely, signal1, signal2, signal3, signal4 and signal5, wherein signal1 and signal2 are both of Float type, signal3 and signal4 are both of UInt type, and signal5 is of boot type, the five kinds of signal information are divided into three kinds, and three kinds of CAN signal classification processing modules are correspondingly generated.
Of course, the CAN signal information may also be classified according to other signal types, such as a transmitting and receiving node of the CAN signal.
S13, according to the preset signal processing logic of each type of CAN signal and calling a Simulink module library, generating the processing logic unit of each CAN signal in each signal classification processing module;
for example, a CAN message corresponds to information of five different CAN signals, namely signal1, signal2, signal3, signal4 and signal5, the five signal information are divided into three types, namely Float, UInt and boot, and correspond to three signal classification processing modules, and five CAN signal processing logic units, namely signal1, signal2, signal3, signal4 and signal5, are respectively generated in the three signal classification processing modules according to preset signal processing logic of each type of CAN signals. For example, referring to fig. 10, the Float signal classification processing module generates respective processing logic units of signal1 and signal 2.
The processing logic unit comprises specific processing logic for filtering, fault detection or fault processing and the like of the CAN signal. Specifically, the signal processing logic includes at least one of filtering, timing, top and bottom edge detection, and bit processing. It should be noted that the signal processing logics of the same type of CAN signals are generally the same (may be set to be different, of course), and the signal processing logics of different types of CAN signals are generally different (may be set to be the same, of course).
S14, carrying out internal parameter configuration on each CAN signal classification processing module;
referring to fig. 11, the purpose of configuring internal parameters of each CAN signal classification processing module is as follows: perfecting each content such as an initial value of each CAN signal classification processing module and an interface display attribute of the module, perfecting each content such as an initial value of a processing logic unit in each CAN signal classification processing module and an interface display attribute of the unit, and accordingly creating a complete CAN message processing module, the CAN signal classification processing module and the processing logic unit. Preferably, the internal parameter configuration includes at least one of an upper limit value and a lower limit value of CAN signal amplitude limiting, a filtering parameter and a fault threshold value.
And S15, connecting the CAN message processing module, the CAN signal classification processing module and the processing logic unit and displaying on a display interface.
Specifically, referring to fig. 12, after the internal parameters of each module and unit are configured, the CAN message processing modules are connected with each other, the CAN signal classification processing modules in each CAN message processing module are connected with each other, and the processing logic units in each CAN signal classification processing module are connected with each other, so that an I/O module model of the vehicle controller software is obtained, and is finally displayed on a display interface.
Compared with the prior art, in the embodiment of the invention, when the I/O module needs to be maintained and updated due to signal change, the embodiment of the invention only needs to obtain the DBC file firstly, and then classifies CAN messages and CAN signals stored in the DBC file to realize classification processing of different CAN signal objects, so that automatic generation of each CAN signal processing module is realized, and further automatic generation of an I/O module model of the whole vehicle controller software is realized.
In this embodiment of the present invention, preferably, after the internal parameter configuration is performed on each of the CAN signal classification processing modules, before the connection lines are performed between the CAN message processing module, the CAN signal classification processing module, and the processing logic unit and the connection lines are displayed on a display interface, the method further includes step S14':
and S14', the CAN message processing module, the CAN signal classification processing module and the processing logic unit are automatically arranged.
Specifically, referring to fig. 12, when the CAN message processing module, the CAN signal classification processing module and the processing logic unit are created, and the modules and the units are automatically arranged, the arrangement result should avoid that the graphs of the modules and the units are mutually staggered when being displayed, that is: the CAN message processing modules are not staggered with each other, the CAN signal classification processing modules in the CAN message processing modules are not staggered with each other, and the processing logic units in the CAN signal classification processing modules are not staggered with each other. Preferably, the arrangement modes include a left alignment mode, a right alignment mode, a centering mode and the like, and the automatic arrangement of the whole I/O module model is realized by calculating the position parameters of each module and unit from bottom to top.
In this embodiment, readability of the I/O module model after generation can be enhanced by automatically arranging the modules in the I/O module model.
In the above embodiment, optionally, after the step of acquiring each type of CAN message information in the DBC file and each type of CAN signal information corresponding to each CAN message information, the method further includes steps S102 to S103:

Preferably, the module interface information includes a signal type, an observed quantity and a standard quantity of the CAN signal information.
S103, generating an initialization file module _ init.m of a corresponding CAN signal classification processing module on the basis of the interface definition file according to the classified CAN signal information;
