Description

Technical Field

[0001] The present invention relates to the technical field of controller information reading, and in particular to a controller coded information writing / reading method and system. Background Art

[0002] Currently, when developing a new controller, if you want to read specific controller information (such as the boot version number, hardware version number, software version number, and torque test data), you need to develop a host computer specifically for the controller to read it. Developing a host computer takes a long time, and when the host computer is not yet available, it is impossible to quickly obtain controller information. Or when performing specific tests, the host computer may not have this function.

[0003] To address this issue, manually sending a specific code can retrieve certain information. However, manual transmission can easily lead to forgetting the message ID and content, and if the amount of information to be read is large, efficiency can be very low, potentially taking one or several hours. Furthermore, some specific information requires sending multiple frames continuously within tens of milliseconds, which is impossible with manual transmission. Summary of the Invention

[0047] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0048] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0049] The embodiment of the present invention provides a controller coding information writing / reading method. For existing controllers, when the host computer has not yet been developed or is not yet available, the method uses self-set code to send and receive messages with the controller, forming a "question and answer" form to read the available information of the controller, solving the technical problem of the need to adapt to the diagnostic program and develop corresponding diagnostic equipment in traditional technologies with high costs. Figure 1 As shown, it may at least include the following steps S101 to S104:

[0050] Step S101: Connect the canoe software platform to the terminal device and the controller respectively.

[0051] In this embodiment of the present invention, the Canoe software platform includes Canoe hardware devices for connecting to a real vehicle bus and Canoe software for installation and deployment. The Canoe hardware devices connect to a controller via a bus, while the Canoe software connects to a terminal device. A terminal device is a mobile device, such as a laptop, that allows users to program and perform read and write operations.

[0052] In step S102, the canoe software platform loads and runs the preset code file to implement information interaction with the controller, so as to send the message-related request and read command signal of the controller coding information to the bus through the can communication device.

[0053] Pre-written code files are used to implement information exchange between the Canoe software platform and the controller. In practice, the CAN protocol uses an event / cycle format to define message requests and read command signals for the controller's coded information. These messages are then sent to the bus via the CAN communication device. This allows for information exchange with the controller over the bus.

[0054] Step S103: Write a program in the CAPEL programming language through the terminal device, and upload the completed CAPEL program to the Canoe software platform as a script.

[0055] It can be understood that the capl program in the embodiment of the present invention is written by professionals according to the controller coding information writing / reading requirements, and serves as the underlying support for the operator to write / read the controller coding information with one click.

[0056] Step S104: Based on the script, a reading module and a writing module for the controller coding information are set on the terminal device in the form of button triggering, and the controller coding information is automatically written / read by clicking the button.

[0057] The embodiment of the present invention is based on the Canoe software platform and a development script using the Capl editing language, thereby achieving the purpose of conveniently writing and reading the internal coding information of the controller. Specifically, a write module, a read module, and a reset module can be set up in the Canoe software platform's GUI interface, and the corresponding functions of each module can be implemented based on the Canoe software platform's script. The write module includes a code input box and a write code operation button; the read module includes a code display box and a read code operation button; and the reset module includes a reset button. The code input box is used to enter coded data; the write code operation button is used to confirm the writing of coded data; the read code operation button is used to confirm the reading of coded data; the code display box is used to display the coded data; and the reset button is used to control the controller to return to its initial state.

[0058] That is to say, in actual operation, you can enter the coding data in the coding input box, click the write coding operation button, and the GUI will display that the writing is successful, and the coding operation for the controller can be completed; click the read coding operation button, and the coding data will be displayed in the writing display box, and the coding reading operation for the controller can be completed.

[0059] In an alternative embodiment, if Figure 2As shown, the Canoe software platform loads and runs a preset code file. After establishing information exchange with the controller, professionals can write a CAPL program based on their needs. The terminal device can respond to the operator's keystroke trigger to run the CAPL program to obtain information or perform tests. Furthermore, professionals can repeatedly debug and modify the preset code file through the terminal device to test the controller and obtain corresponding test data information.

[0060] In an optional embodiment, when executing the read and write operations of the controller coding information: in response to a click on the read coding operation button, the embodiment of the present invention causes the Canoe program to read the signal list / matrix information of the CAN protocol, which includes the specific signals required for reading the coding to accommodate the different signal requirements of different vehicle models; sends a message instruction ID in the form of event / cycle to obtain the coding; then reads the hexadecimal coded data through the message instruction ID command, writes the coded data to a specific document, and displays it in the coding display box. It can be understood that if the coding information of the controller is read successfully, the document contains the message data of the corresponding ID.

[0061] Furthermore, if Figure 3 As shown, in response to a click operation on the write coding operation button, the embodiment of the present invention writes the signal list / matrix information of the CAN protocol in the MATLAB program. The signal list / matrix information includes the specific signals required for writing coding to adapt to the different signal requirements of different vehicle models; the corresponding ID message in the CAP1 program is used to write the hexadecimal message data, and the ID message request command containing the coding data is sent through the CANoe software platform to request the writing of the coding data; and then the coding information is written through the message (the written coding data is Data1). It should be noted that in the "request to write coding data" step, it is determined whether the controller feedback allows writing coding. If the controller feedback allows writing coding, the coding data is written to the controller; if the controller feedback does not allow writing coding, check whether the ID message request command is correct and / or whether the CAN communication is normal. After writing the coding data through the ID message, the controller sends a successful response Write_Success message, and the GUI interface displays a successful write.

[0062] As an example, the code to read the controller encoding information is as follows:

[0063]

[0064]

[0065]

[0066]

[0067] Split the string according to the specified delimiter similar to the python split function

[0069]

[0070]

[0071] The embodiment of the present invention provides a controller coding information writing / reading method and system, which respectively connects the Canoe software platform to the terminal device and the controller; the Canoe software platform loads and runs a preset code file to realize information interaction with the controller, so as to send the message-related request and read command signal of the controller coding information to the bus through the CAN communication device; through the terminal device, a program is written in the CAPEL programming language, and the written CAPEL program is uploaded to the Canoe software platform as a script; based on the script, a reading module and a writing module for the controller coding information are set in the form of key triggering on the terminal device, and the controller coding information is automatically written / read by clicking the key. Through the present invention, the controller is read and tested in the form of CAPEL code. It only needs to connect the computer to the controller or the whole vehicle, run the written CAPEL code through the Canoe operation, read the corresponding controller information, and perform specific tests on the controller.
