[0061] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The specific operating methods in the method embodiments can also be applied to device embodiments or system embodiments. It should be noted that in the description of the present application, "multiple" is understood as "at least two". "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. A is connected to B, which can represent: A is directly connected to B and A is connected to B through C. In addition, in the description of the present application, words such as "first" and "second" are only used to distinguish the purpose of description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0062] The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0063] In automotive CAN bus communications, after a signal is sent from one controller, it often needs to pass through multiple modules before it can be received by another controller.

[0064] For example, refer to Figure 1 , is a schematic diagram of a signal transmission path. Figure 1In the example, after the application software of controller 1 sends out signal sig1, it continues to pass through multiple modules of controller 1, such as the real-time runtime environment (RTE), COM, high-voltage power distribution unit (PDU), CAN transport layer protocol (CANTP), CAN interface module (CANIF), CAN, CAN driver (CAN_Drv), etc., and is transmitted to the CAN bus. It continues to pass through multiple modules such as CAN_Drv, CAN, CANIF, CANTP, PDU, COM, RTE, etc. before being received by controller 2. After multiple layers of transmission, it can reach the corresponding application software of controller 2. In the process of signal transmission, if there is a problem in the development of any module, the signal will not be transmitted correctly, thus affecting the normal operation of the vehicle function and even bringing potential safety hazards to the vehicle and the driver.

[0065] In the related art, in order to ensure the correct transmission of signals, usually during the product development process, test engineers write corresponding test cases and use HIL testing to detect whether the transmission of CAN signals is correct.

[0066] However, this signal transmission detection method usually targets each controller and is equipped with a corresponding simulation system to detect the corresponding signal transmission of the controller. This test link can only verify whether the transmission and reception of a controller are correct, but cannot simultaneously detect the signal transmission between the two controllers corresponding to the two ends of the signal transmission and reception.

[0067] In order to solve the above problems, the present application provides a signal transmission detection method, device, electronic device and storage medium. When the first controller obtains the wake-up instruction, it generates a first signal corresponding to the wake-up instruction, and based on the first signal, generates a first message of a preset number of frames. Further, the first message is sent to the second controller, so that after receiving the first message, the second controller assigns one or more signals corresponding to the first message, and compares the comparison results with the test values ​​respectively, to obtain the signal transmission detection result between the first controller and the second controller. In this process, the signal transmission detection result is completed based on the mutual cooperation between the first controller and the second controller. Therefore, based on the signal transmission detection result, the signal transmission between the two controllers corresponding to the signal sending and receiving ends can be detected. In addition, the signal transmission detection method is not only applicable to the detection environment, but also can realize signal transmission self-checking in the actual stage, avoiding functional and even safety problems in the subsequent use stage caused by development and testing errors.

[0068] Among them, the methods, devices, electronic devices and storage media in the embodiments of the present application are based on the same technical concept and the principles of solving the problems are similar. Therefore, the embodiments of the devices, electronic devices, storage media and methods can refer to each other, and the repeated parts will not be repeated.

[0069] In particular, the preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application, and the embodiments of the present application and the features in the embodiments may be combined with each other if there is no conflict.

[0070] Embodiment 1:

[0071] like Figure 2 FIG. 1 is a flow chart of a signal transmission detection method provided by the present application. The method is applied to a first controller and specifically includes the following steps:

[0072] S201, in response to obtaining a wake-up instruction, generating a first signal corresponding to the wake-up instruction, where the value carried by the first signal is a test value.

[0073] In the embodiment of the present application, the wake-up instruction is used to activate the first controller. When the first controller receives the wake-up instruction, it generates a second signal corresponding to the wake-up instruction in response to the wake-up instruction. For example, Figure 1 The signal sig1 in is a second signal.

[0074] Further, the first controller assigns the generated second signal according to the test value, and uses the assigned second signal as the first signal. The test value is pre-defined in the requirements stage, which is one of the most critical stages in the product development process. It aims to clarify and define the product's functions, performance, constraints, and interfaces, and accurately and professionally describe user expectations to the development team to ensure the effectiveness of the product development process.

[0075] S202, based on the first signal, generating a first message of a preset frame number, wherein the value carried by the first message is a self-test value, and the self-test value indicates that the signal carried by the first message is in a detection state.

[0076] In an embodiment of the present application, after the first controller generates the first signal, it generates a second message with a preset number of frames based on the first signal, wherein the preset number of frames may be 3 frames, 4 frames or 5 frames, and no specific limitation is made here.

[0077] After the second message is obtained, a self-test status bit is defined in the second message, and the self-test status bit is assigned a value according to the self-test value to obtain the first message. The self-test value is assigned to 1, and of course, it can also be set to other values, which are not specifically limited here. Then all signals in the first message are in the detection state.

[0078] By setting a self-test value for the first message signal, when the second controller that receives the first message can identify the self-test value, it starts to detect the signal transmission between the first controller and the second controller.

[0079] S203, sending a first message to the second controller, so that after receiving the first message, the second controller can obtain a signal transmission detection result between the first controller and the second controller based on the comparison results between one or more signal assignments corresponding to the first message and the test values.

[0080] In the embodiment of the present application, after the first controller generates the first message including the self-test value, it sends the first message to the second controller.

[0081] After receiving the first message, the second controller assigns one or more signals corresponding to the first message, compares them with the test values, obtains one or more comparison results, and obtains the signal transmission detection result between the first controller and the second controller according to the comparison results. The specific implementation method can refer to the subsequent embodiment 2, which will not be repeated here.

[0082] After the first controller sends out the first message with the preset frame number, the subsequently generated second signal is no longer assigned according to the test value, but the third message is generated by the second signal according to the actual value, and the self-test status bit in the third message is assigned to 0 instead of the self-test value. From then on, the first message used for signal transmission detection is no longer generated, indicating that for the first controller, the signal transmission self-test between the first controller and the second controller is completed.

[0083] The above signal transmission detection process of the first controller can also be regarded as the network initialization process of the first controller, such as Figure 3 FIG. 1 is an example diagram of the initialization process of the first controller, which specifically includes the following steps:

[0084] Step 1: First controller network wake-up;

[0085] Step 2: The self-check flag signal is set to 1, that is, the self-check status bit in the sent message is assigned a value of 1;

[0086] Step 3: Set the values ​​of all signals to test values;

[0087] Step 4: Send 3 frames of messages to the second controller;

[0088] Step 5: The self-check flag signal is set to 0, that is, the self-check status bit in the subsequent sent message is assigned to 0;

[0089] Step 6: Assign the values ​​of all signals to actual values;

[0090] Step 7: Self-test is completed.

[0091] In the above signal transmission detection method, the first controller generates a first signal corresponding to the wake-up instruction, and based on the first signal, generates a first message of a preset frame number, and further sends the first message to the second controller, so that after receiving the first message, the second controller assigns one or more signals corresponding to the first message, and compares the results with the test values ​​to obtain the signal transmission detection result between the first controller and the second controller. In this process, the signal transmission detection result is completed based on the mutual cooperation between the first controller and the second controller. Therefore, based on the signal transmission detection result, the signal transmission between the two controllers corresponding to the signal sending and receiving ends can be detected.

[0092] In addition, this signal transmission detection method is not only applicable to the detection environment, but can also realize signal transmission self-checking in the actual stage, avoiding functional and even safety problems in the subsequent use stage caused by development and testing errors.

[0093] Embodiment 2:

[0094] like Figure 4 FIG. 1 is a flow chart of a signal transmission detection method provided by the present application. The method is applied to the second controller and specifically includes the following steps:

[0095] S401, when receiving a first message sent by a first controller, updating the accumulated number of frames received of the first message;

[0096] In an embodiment of the present application, after the second controller receives the first message sent by the first controller, it updates the cumulative frame number of the received first message. For example, after previously receiving 2 frames of the first message, the next time the first message is received, the cumulative frame number is updated to 3. Of course, other counting methods can also be used, which are not specifically limited here.

[0097] In one embodiment, when the second controller receives the first message, it is also necessary to parse the first message to obtain a corresponding message signal.

[0098] S402, when the accumulated number of frames is less than or equal to the preset number of frames, determining whether the value assigned to the self-check status bit in the first message is a self-check value;

[0099] In an embodiment of the present application, after determining the cumulative number of frames of the first message, the second controller determines whether the cumulative number of frames is less than or equal to the preset number of frames. If the cumulative number of frames is greater than the preset number of frames, the second controller assigns one or more signals corresponding to the message signal obtained by parsing the first message, and transmits them to the corresponding application program; if the cumulative number of frames is less than or equal to the preset number of frames, it is further determined whether the value assigned to the self-test status in the first message is a self-test value. Here, the self-test value indicates that the signal in the message is used to test the signal transmission between the first controller and the second controller. Here, the value of the self-test value is 1. Of course, it can also be other values, and there is no specific limitation here.

[0100] S403, if yes, assigning values ​​to one or more signals corresponding to the first message, respectively comparing them with preset test values, and obtaining a signal transmission detection result between the first controller and the second controller according to the comparison result;

[0101] In an embodiment of the present application, if the value corresponding to the self-test status bit in the first message signal is a self-test value, it indicates that the first message sent by the first controller is used for signal transmission detection. At this time, the signal assignments of one or more message signals corresponding to the first message are respectively compared with preset test values ​​to obtain one or more corresponding comparison results, wherein the test value is set in the demand stage, indicating that the signal in the message is used to test whether the signal transmission is abnormal, and the comparison results obtained include consistent comparison and inconsistent comparison.

[0102] In one embodiment, if there is a comparison inconsistency in one or more comparison results, it is confirmed that the signal transmission between the first controller and the second controller is abnormal, and the corresponding signal transmission detection result is detection failure. Otherwise, it is confirmed that the signal detection result is detection passing.

[0103] For example, the first message contains three signals, namely, signal sigA, signal sigB, and signal sigC, wherein the signal value corresponding to signal sigA is 1, the signal value corresponding to signal sigB is 1, and the signal value corresponding to signal sigC is 0. In the product development requirement stage, the preset test value is 1, then the signal values ​​corresponding to signal sigA and signal sigB are respectively consistent with the test values, while the signal value corresponding to signal sigC is inconsistent with the test value. Therefore, among the three comparison results, there is an inconsistent comparison result. Therefore, it is confirmed that there is an abnormality in the signal transmission between the first controller and the second controller, and the corresponding signal transmission detection result is detection failure.

[0104] S404: If not, confirm that the signal transmission detection result between the first controller and the second controller is detection failure.

[0105] In an embodiment of the present application, when the cumulative number of frames is less than or equal to the preset number of frames, if the assigned value corresponding to the self-test status bit in the first message signal is inconsistent with the self-test value, it is directly confirmed that the signal transmission between the first controller and the second controller is abnormal, and the corresponding signal transmission detection result is detection failure.

[0106] When the signal transmission detection result obtained by the second controller is that the detection fails, functional protection measures will be taken, such as parking, lowering high voltage, etc.

[0107] For example, refer to Figure 5 , is a flowchart of a second controller signal transmission detection step, which specifically includes the following steps:

[0108] Step 1: Receive the first message;

[0109] Step 2: The number of the first message increases by 1;

[0110] Step 3: Analyze the first message and obtain the message signal;

[0111] Step 4: Determine whether the cumulative number of the first message is less than or equal to 3, if not, execute step 5, if yes, execute step 7;

[0112] Step 5: Assign the parsed message to the corresponding application and execute Step 6;

[0113] Step 6: End;

[0114] Step 7: Determine whether the self-test status bit in the first message is 1, if not, execute step 8, if yes, execute step 9;

[0115] Step8: Self-check signal failure;

[0116] Step 9: Compare the signal values ​​of the message signals one by one to see if they are equal to the test values;

[0117] Step 10: Determine whether all the assigned signals are equal to the test value. If so, execute step 11 and step 6, otherwise execute step 8;

[0118] Step 11: The message self-check passes.

[0119] In order to further elaborate the technical solution disclosed in the present application, the following description is made with the first controller as the signal sending end and the second controller as the signal receiving end. Figure 6 FIG. 1 is a schematic diagram of a signal transmission detection method provided in an embodiment of the present application, which specifically includes the following steps:

[0120] Step 1: The first controller obtains the wake-up command;

[0121] Step 2: Generate a first signal corresponding to the wake-up instruction, where the value carried by the first signal is a test value;

[0122] Step 3: Generate a first message with a preset number of frames, where the value carried by the first message is a self-test value;

[0123] Step 4: Send the first message to the second controller;

[0124] Step 5: The second controller updates the accumulated frame number of the first message;

[0125] Step 6: When the accumulated number of frames is less than or equal to the preset number of frames, determine whether the value assigned to the self-test status bit in the first message is a self-test value;

[0126] Step 7: If yes, assign values ​​to one or more signals corresponding to the first message, compare them with preset test values ​​respectively, and obtain the signal transmission detection result between the first controller and the second controller according to the comparison result;

[0127] Step 8: If not, confirm that the signal transmission detection result between the first controller and the second controller is detection failure.

[0128] It should be noted that the specific implementation method of the steps executed by the controller in this schematic diagram can refer to the above-mentioned embodiment 1 and embodiment 2, and will not be elaborated here.

[0131] The sending module 702 is used to send a first message to the second controller, so that after receiving the first message, the second controller can obtain the signal transmission detection result between the first controller and the second controller according to the comparison results between one or more signal assignments corresponding to the first message and the test values.
