[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the application clearer, the following will combine the drawings in the embodiments of the application to clearly and completely describe the technical solutions in the embodiments of the application. Obviously, the described embodiments are some of the embodiments of the application, not all the embodiments.

[0035] As Figure 1As shown, developing a new new energy vehicle requires building a vehicle control model 1 of an electronic control system, the model is roughly divided into eight modules, which are auxiliary system 2, fault handling 3, logic control 4, power-on and power-off management 5, communication fault 6, input and output 7, power system 8 and gear management 9, product developers work in cooperation, and each module is developed in parallel. When the developers work in modules, there are problems such as signal crossing between modules, inconsistent signal definition, and signal reuse, which further leads to simulation failure, and more seriously, it will cause real vehicle debugging failure. In order to solve this problem, the signal matching tool is developed, which requires the developer to sort out the signal and enter before model development, and timely confirm the existence and actual definition of the signal, and then reference to the own model building, improve the model development efficiency and accuracy.

[0036] In a first aspect, the present application provides a new energy vehicle electronic control system signal data management platform, as shown in Figure 2 As shown, it comprises a signal input unit 210, a signal database 220, a signal preview unit 230 and a signal search unit 240;

[0037] The signal input unit 210 is used for inputting the signal attribute information in the current new energy vehicle control model according to the demand into the signal database, and the vehicle control model comprises a plurality of different modules; the signal database 220 is used for storing the signal attribute information; the signal preview unit 230 is used for displaying the signal attribute information according to the module to which it belongs; and the signal search unit 240 is used for searching the required signal attribute information from the signal database, so that the developer can search and compare the signal attribute information through the signal search unit before determining the input and output signals of the model.

[0038] The signal attribute information of each module in the vehicle control model is input into the signal database according to the actual demand, and in the product module development process, the user can search through the signal search unit to find the required signal attribute information; so that the product control model developer can search and compare the signal information through the signal search module before determining the input and output signals of the model, avoiding the mismatch of data type or signal name in signal information interaction, signal repeated definition and other errors, also improving the success rate of model simulation, saving time cost.

[0039] Specifically, the signal attribute information includes but is not limited to the Chinese name of the signal, the English name of the signal, the type of the signal and the specific meaning of the signal, and in some embodiments, the signal attribute information can also include the value range of the signal and other information.

[0040] As an optional implementation, the signal input unit 210 comprises a verification subunit for verifying whether the Chinese name and English name in the signal attribute information are in a legal format.

[0041] Specifically, the legal Chinese name in the input signal attribute information can be pre-defined to contain one or more of the following: numbers, letters, underscores, and Chinese characters; the legal English name can be required to contain one or more of the following: numbers, letters, and underscores, for example, for a certain control signal, the legal Chinese name can be control signal 1, and the legal English name can be contr_1. If an illegal character is input, an alarm message is output, which includes but is not limited to a pop-up warning.

[0042] The signal type can classify signals from different angles, such as classifying signals into analog signals and digital signals from the perspective of time continuity, classifying signals into periodic signals and aperiodic signals from the perspective of repeatability, classifying signals into one-dimensional signals and multi-dimensional signals from the perspective of dimension, and classifying signals into deterministic signals and random signals from the perspective of randomness.

[0043] As an optional implementation, the signal preview unit 230 displays the signal attribute information according to the corresponding module in the form of a tree diagram.

[0045] As an optional implementation, the signal search unit 240 is specifically configured to search for the required signal attribute information from the signal database according to a keyword.

[0046] In specific implementation, a search box can be designed, and the user can search for the required signal attribute information by inputting a keyword in the search box. In addition, other search methods such as semantic search can be used to search for all information stored in the database for the required signal, providing a reference for pre-addition of signals.

[0047] As an optional implementation, the signal preview unit 230 includes an information echoing subunit, which is configured to further display other attribute information of the signal according to the name information of the signal.

[0048] When the signal preview unit 230 displays the signal attribute information according to the corresponding module, for example, in the form of a tree diagram, the signal names are displayed under the branches of the tree diagram. In order to further understand other attribute information of the signal, the echoing subunit can be used to display the detailed attribute information of the signal. For example, the signal name under the tree diagram can be designed to be double-clicked, and the system will automatically search for other signal attribute information stored in the signal database and display the information.

[0049] The echo sub-unit can simplify the display interface of the signal preview unit 230, so that the detailed attribute information of the signal is not displayed on the interface temporarily, and the required detailed attribute information of the signal (for example, the English name, the meaning of the signal, and the value range of the signal, etc.) can be displayed through the autonomous selection of the user when necessary, so as to meet the actual needs of the user.

[0050] In addition, the signal preview unit 230 can also realize autonomous modification of signal attribute information according to requirements.

[0051] As an optional implementation, the management platform further comprises a deletion unit for deleting unnecessary signal attribute information.

[0052] If the newly added signal is successfully entered, the information filled in by the current signal entry unit 210 will be emptied through the deletion unit; if the historical search records in the signal search unit 240 are too many, the deletion unit can also be used for deletion, for example, manually clicking a button to empty.

[0053] As an optional implementation, the signal database adopts an XML format.

[0054] The XML file is used as the database, which does not depend on other database systems, provides functions of adding, deleting, modifying and searching externally, is simple and fast to configure, and can avoid calling third-party software.

[0055] It should be noted that the management platform described in the present application can be applied to, but is not limited to, a laptop computer and a desktop computer, and can be applied to a win7 system or a win10 system in software.

According to the signal attribute information entry process Figure 4 From the beginning, inputting the Chinese name of the signal, inputting the English name of the signal, inputting the type of the signal, inputting the meaning of the signal, confirming the signal and ending the entry, a complete record will be successfully entered into the signal database after the process is ended.

[0060] The signal type can classify the signal from different angles, such as classifying the signal into an analog signal and a digital signal from time continuity, classifying the signal into a periodic signal and a non-periodic signal from repeatability, classifying the signal into a one-dimensional signal and a multi-dimensional signal from dimension, classifying the signal into a deterministic signal and a random signal from randomness, and the like.

[0063] In the specific implementation, if the developer needs to find whether a certain signal exists in the current signal database or find the attribute of a certain signal, the developer can input the keyword in the search box, click the search button, and search the database. Figure 5 The signal search process is expanded to search, specifically, inputting the keyword in the search box, clicking the search button, searching the database, if the database is not found, checking the keyword and returning to input the keyword again; if the database search is successful, displaying the found signal attribute information, and then ending the search.
