[0088] Please refer toFigure 2 which shows a flow chart of a signal library management method according to an example embodiment of the present application. Referring to Figure 2 The method comprises the following steps.

[0089] Step 201: determining a plurality of vehicle controllers to be managed, the protocol types of the plurality of vehicle controllers comprising at least one of a vehicle controller local area network (CAN) protocol, a modified communication CAN (CANFD) protocol of the vehicle controller local area network, and a local interconnect network (LIN) protocol.

[0090] The plurality of vehicle controllers can be controllers of the same vehicle, or controllers of different vehicles. In the case that the plurality of vehicle controllers are controllers of different vehicles, the plurality of vehicle controllers can be all the controllers used by a vehicle manufacturer, and the vehicle manufacturer can produce a plurality of vehicle models, i.e., the plurality of vehicle controllers in the example embodiment of the present application can be applied to a plurality of vehicle models.

[0091] The protocol types of the plurality of vehicle controllers comprise at least one of the CAN protocol, the CANFD protocol, and the LIN protocol. In a possible implementation, the plurality of vehicle controllers are vehicle controllers of the same protocol type; for example, the plurality of vehicle controllers are all vehicle controllers of the CAN protocol, or the plurality of vehicle controllers are all vehicle controllers of the CANFD protocol, or the plurality of vehicle controllers are all vehicle controllers of the LIN protocol, so that the present application can manage test messages of a plurality of vehicle controllers of the same protocol. In another possible implementation, the plurality of vehicle controllers are vehicle controllers of different protocol types; for example, the plurality of vehicle controllers comprise vehicle controllers of the CAN protocol, vehicle controllers of the CANFD protocol, and vehicle controllers of the LIN protocol, so that the present application can be compatible with the CAN, CANFD, and LIN protocols, and meet the needs of signal differences between vehicle controllers of different protocols.

[0092] Step 202: controlling the plurality of vehicle controllers to respectively send test messages, the test messages sent by the plurality of vehicle controllers comprising test messages of at least one of the CAN protocol, the CANFD protocol, and the LIN protocol, and the test messages respectively sent by the plurality of vehicle controllers being used to test the transceiving relationship between the plurality of vehicle controllers.

[0093] The vehicle controller of the CAN protocol is used to send test messages of the CAN protocol, the vehicle controller of the CANFD protocol is used to send test messages of the CANFD protocol, and the vehicle controller of the LIN protocol is used to send test messages of the LIN protocol. The computer device can control the plurality of vehicle controllers to simultaneously send test messages, or can control the plurality of vehicle controllers to sequentially send test messages; in the example embodiment of the present application, the timing of the plurality of vehicle controllers sending test messages is not specifically limited.

[0094] Step 203: For any test message, determine the message information of the test message, the message information including the message identifier, the protocol format, the transmission rate switching identifier, the message name, the message type, the message length, the message sending type, the message cycle time, the fast cycle of the message sending, the number of fast sending of the message, the message delay time and the signal name included in the test message.

[0095] The message identifier is a symbol for uniquely identifying the test message; for example, please refer to Figure 3 , the identifiers of the test messages are 0x49C, 0x031, 0x021, 0x26B, 0x195, 0x1B8, 0x1BC, 0x159 and 0x145 respectively. The protocol format is used to identify the protocol format of the controller sending the test message; for example, the protocol format can be Standard CAN, Standard CAN NFD or Standard LIN, etc. The transmission rate switching identifier is used to identify whether the transmission rate of the test message corresponding thereto is switched; for example, the transmission rate switching identifier is 1, which is used to indicate that the transmission rate of the test message corresponding thereto is switched, that is, the vehicle controller sending the test message and the vehicle controller receiving the test message are not vehicle controllers of the same protocol, so that the transmission rate of the test message is switched; the transmission rate switching identifier is 0, which is used to indicate that the transmission rate of the test message corresponding thereto is not switched, that is, the vehicle controller sending the test message and the vehicle controller receiving the test message are vehicle controllers of the same protocol, so that the transmission rate of the test message will not be switched.

[0096] The message name can be composed of the vehicle controller name + serial number; for example, please continue to refer to Figure 3 , the plurality of vehicle controllers include 4 ACUs, and the message names of the test messages sent by the plurality of vehicle controllers can be ACU_1, ACU_2, ACU_3 and ACU_4; for another example, the plurality of vehicle controllers include 3 ADS_EPS and 2 ADS_ONEBOX, and the message names of the test messages sent by the plurality of vehicle controllers can be ADS_EPS_1, ADS_EPS_2, ADS_EPS_3, ADS_ONEBOX_1 and ADS_ONEBOX_2.

[0097] The message type can be IL; the message length can be 8 or 24; the message sending type can be Cycle or CE; the message cycle time is used to identify the sending cycle of the message, for example, the message cycle time can be 100, 10 or 20; the message fast sending times are used to represent the number of times the test message is sent fast; for example, the message fast sending times are 0 or 6. The message delay time is used to represent the difference between the receiving time and the sending time of the test message; for example, the message delay time is 0 or 5.

[0098] Step 204: Control the multiple vehicle controllers to perform the receiving operation of the test message.

[0099] The computer device controls the multiple vehicle controllers to perform the receiving operation of the test message, and the vehicle controllers having the transceiving relationship with the vehicle controller sending the test message will receive the test message. In this step, the multiple vehicle controllers are controlled to perform the receiving operation of the test message, so as to ensure the homology of the vehicle controllers receiving the test message, and the related information of the test message of the multiple vehicle controllers is updated at one time through the following steps 205-208, so as to avoid omission.

[0100] Step 205: Determine the vehicle controllers receiving the test message, and determine the vehicle controllers sending the test message and the vehicle controllers receiving the test message as the associated vehicle controllers of the test message, the associated vehicle controllers of the test message being used to represent the transceiving relationship between the multiple vehicle controllers.

[0101] The associated vehicle controllers of the test message are listed at the end of the test signal, and the associated vehicle controllers of the test message can represent the transceiving relationship between the multiple vehicle controllers, so as to facilitate the search for the vehicle controllers associated with the test message; when it is necessary to search for problems, the vehicle controllers associated with the test message can be quickly located based on the associated vehicle controllers of the test message, so as to facilitate positioning and tracking.

[0102] For example, please continue to refer to Figure 3 , Figure 3 The lower part is the vehicle controllers associated with the test message; for example, for the test message 0x031, the vehicle controller sending the test message 0x031 is CGW_DA, and the vehicle controllers receiving the test message 0x031 are PDC_DA and FCM_DA. For another example, for the test message 0x021, the vehicle controllers sending the test message 0x021 are CGW_DA and CGW_DK, and the vehicle controller receiving the test message 0x031 is FCM_DA; in Figure 3 the vehicle controllers marked with s are the vehicle controllers sending the corresponding test messages, and the vehicle controllers marked with r are the vehicle controllers receiving the corresponding test messages.

[0103] Step 206: determining the vehicle model information of the vehicle to which the associated vehicle controller of the test message is applied.

[0104] The same vehicle controller can be applied in one or more vehicles; therefore, the vehicle model information of the vehicle to which the associated vehicle controller of the test message is applied includes multiple vehicle model information.

[0105] Step 207: determining the network segment to which the test message belongs.

[0106] Step 208: storing the relevant information of the test message, the associated vehicle controller of the test message, the vehicle model information of the vehicle to which the associated vehicle controller is applied, and the network segment to which the test message belongs as a record item in the signal library.

[0107] The signal library can be an Excel table; and the table header of the Excel table has a filtering function; therefore, the computer device can filter the information to be queried from the Excel table based on the filtering function of the Excel table. In this step, the test messages sent by multiple vehicle controllers are stored in the signal library, and the same test message appears only once in the signal library, ensuring the uniqueness of the test message.

[0108] The test messages sent by multiple vehicle controllers include CAN protocol test messages, CANFD protocol test messages, and LIN protocol test messages; therefore, the embodiments of the present application can implement test messages compatible with different protocols of CAN, CANFD, and LIN, maintain test messages in three formats in the same Excel table, facilitate the search of test messages and the tracking of message routing. At the same time, it is convenient for the transmission of test messages between network segments without protocols, the establishment of message routing of test messages between different network segments, and has stronger compatibility.

[0109] In the embodiments of the present application, the test messages of multiple vehicle controllers are managed in a signal library, and the associated vehicle controller of the test message and other relevant information of the test message are stored in the signal library, so that when troubleshooting, the associated vehicle controller and other relevant information of the test message can be quickly determined from the signal library based on the test message, reducing the troubleshooting time and improving the troubleshooting efficiency.

[0110] In addition, the message information of the test message is stored in the signal library, which facilitates the management of the test message based on the message information of the test message.

[0111] Please refer to Figure 4 , which shows a flowchart of the signal library management method according to an exemplary embodiment of the present application. Please refer to Figure 4 , which shows a flowchart of the signal library management method according to an exemplary embodiment of the present application. Please refer to

[0112] Step 401: The computer device determines a plurality of vehicle controllers to be managed, and the protocol types of the plurality of vehicle controllers include at least one of a vehicle controller local area network (CAN) protocol, a CAN with flexible data rate (CANFD) protocol, and a local interconnect network (LIN) protocol.

[0113] In some embodiments, this step is the same as step 201, which will not be repeated here.

[0114] Step 402: The computer device controls the plurality of vehicle controllers to respectively send test messages, and the test messages sent by the plurality of vehicle controllers include at least one of test messages of the CAN protocol, test messages of the CANFD protocol, and test messages of the LIN protocol, and the test messages respectively sent by the plurality of vehicle controllers are used to test the transceiving relationship between the plurality of vehicle controllers.

[0115] In some embodiments, this step is the same as step 202, which will not be repeated here.

[0116] Step 403: For any test message, the computer device determines message information of the test message, and the message information includes a message identifier, a protocol format, a transmission rate switching identification bit, a message name, a message type, a message length, a message sending type, a message cycle time, a fast cycle of message sending, a number of fast sending of the message, a message delay time, and a signal name included in the test message.

[0117] In some embodiments, this step is the same as step 203, which will not be repeated here.

[0118] Step 404: The computer device controls the plurality of vehicle controllers to perform a receiving operation of the test message.

[0119] In some embodiments, this step is the same as step 204, which will not be repeated here.

[0120] Step 405: The computer device determines a vehicle controller that receives the test message, and determines a vehicle controller that sends the test message and the vehicle controller that receives the test message as an associated vehicle controller of the test message, and the associated vehicle controller of the test message is used to represent the transceiving relationship between the plurality of vehicle controllers.

[0121] In some embodiments, this step is the same as step 205, which will not be repeated here.

[0122] Step 406: The computer device determines vehicle model information of an automobile to which the associated vehicle controller of the test message is applied.

[0123] In some embodiments, this step is the same as step 206, which will not be repeated here.

[0124] Step 407: The computer device determines the network segment to which the test message belongs.

[0125] In some embodiments, the present step is the same as step 207, which will not be repeated here.

[0126] Step 408: The computer device stores the relevant information of the test message, the associated vehicle controller of the test message, the vehicle model information of the vehicle to which the associated vehicle controller is applied, and the network segment to which the test message belongs as a record item in the signal library.

[0127] In some embodiments, the present step is the same as step 208, which will not be repeated here.

[0128] Step 409: The computer device receives a first query instruction, which carries the message identifier of the first test message.

[0129] The development and improvement of the functions of the vehicle controller (which can be embodied in the form of test messages) can be divided into blocks and given to different development teams; and the associated vehicle controller of a certain function can be queried through a query function, and the relevant information of the vehicle controller is provided to the development team, at which time the first query instruction is triggered to the computer device, and the first query instruction carries the message identifier of the first test message. In a possible implementation manner, the signal library stores the relevant information of the test message in the form of an Excel table, and the table header of the Excel table has a query function; in the present step, the first test message is filtered through the table header of the Excel table to trigger the first query instruction to the computer device.

[0130] Step 410: The computer device obtains, based on the message identifier of the first test message, a record item in which the message identifier of the first test message is located from the signal library.

[0144] Step 505: The computer device determines the vehicle controller receiving the test message, determines the vehicle controller sending the test message and the vehicle controller receiving the test message as the associated vehicle controller of the test message, and the associated vehicle controller of the test message is used to represent the transceiving relationship between the plurality of vehicle controllers.

[0145] In some embodiments, the present step is the same as step 205, which will not be repeated here.

[0146] Step 506: The computer device determines the vehicle model information of the vehicle to which the associated vehicle controller of the test message is applied.

[0147] In some embodiments, the present step is the same as step 206, which will not be repeated here.

[0148] Step 507: The computer device determines the network segment to which the test message belongs.

[0150] Step 508: The computer device stores the related information of the test message, the associated vehicle controller of the test message, the vehicle model information of the vehicle to which the associated vehicle controller is applied, and the network segment to which the test message belongs as a record item in the signal library.

[0151] In some embodiments, the present step is the same as step 208, which will not be repeated here.

[0152] Step 509: The computer device receives a second query instruction, and the second query instruction carries the controller identifier of the first vehicle controller.

[0153] In a possible implementation, the signal library stores the related information of the test message in the form of an Excel table, and the table header of the Excel table has a query function; in the present step, the controller identifier of the first vehicle controller is filtered through the table header of the Excel table to trigger the second query instruction to the computer device.

[0154] Step 510: The computer device determines the controller identifier of the second vehicle controller, and the second vehicle controller is the vehicle controller receiving the test message sent by the first vehicle controller.

[0155] The signal library stores the sending and receiving relationship of the test message; in a possible implementation manner, the first vehicle controller is a vehicle controller that sends the test message; then, the step in which the computer device determines the controller identifier of the second vehicle controller can be: the computer device determines the test message sent by the first vehicle controller, determines the associated vehicle controller of the test message from the signal library based on the test message sent by the first vehicle controller, and determines the controller identifier of the second vehicle controller from the associated vehicle controller of the test message.

[0156] Step 511: The computer device generates routing information based on the controller identifier of the first vehicle controller and the controller identifier of the second vehicle controller.

[0157] In a possible implementation manner, the first vehicle controller is a controller that sends the test message, and the second vehicle controller is a controller that receives the test message; then, the routing information is the controller identifier of the first vehicle controller-the controller identifier of the second vehicle controller. In another possible implementation manner, the first vehicle controller is a controller that receives the test message, and the second vehicle controller is a controller that receives the test message; then, the routing information is the controller identifier of the second vehicle controller-the controller identifier of the first vehicle controller.

[0158] In another possible implementation manner, the protocol type of the first vehicle controller and the protocol type of the second vehicle controller are different; correspondingly, the step in which the computer device generates the routing information based on the controller identifier of the first vehicle controller and the controller identifier of the second vehicle controller can be implemented through the following steps (1) to (3), comprising:

[0159] (1) The computer device determines the first message identifier and the first transmission rate of the test message sent by the first vehicle controller.

[0160] Since the message identifiers and transmission rates of vehicle controllers between different protocols are different; for example, the vehicle controller of the LIN protocol sends the test message, and the vehicle controller of the CAN protocol receives the test message, the message identifier and the transmission rate (sending rate) of the test message sent by the vehicle controller of the LIN protocol are different from the message identifier and the transmission rate (receiving rate) of the test message received by the vehicle controller of the CAN protocol; therefore, the embodiment of the application can be compatible with the test message with variable ID and variable rate.

[0161] (2) The computer device determines a second message identifier and a second transmission rate of the test message received by the second vehicle controller from the first vehicle controller.

[0162] (3) The computer device generates routing information based on the controller identifier of the first vehicle controller, the first message identifier and the first transmission rate of the test message, and the controller identifier of the second vehicle controller, the second message identifier and the second transmission rate of the test message.

[0163] In a possible implementation, the first vehicle controller is a controller that sends the test message, and the second vehicle controller is a controller that receives the test message; the routing information is the controller identifier of the first vehicle controller-the controller identifier of the second vehicle controller, and the first message identifier and the first transmission rate of the test message sent by the first vehicle controller are marked in the routing information, and the second message identifier and the second transmission rate of the test message received by the second vehicle controller are marked in the routing information.

[0164] In the embodiments of the present application, since the multiple vehicle controllers are vehicle controllers of different network segments, the embodiments of the present application can route the test messages that need to be routed in different network segments, implement the routing of test messages among different protocols of CAN, CANFD and LIN, and quickly split out the routing information to avoid errors caused by manual preparation of the routing information.

[0165] Please refer to Figure 6 which shows a flowchart of a signal library management method according to an example embodiment of the present application. Please refer to Figure 6 The method comprises the following steps.

[0171] In some embodiments, this step is the same as step 203, which will not be repeated here.

[0172] Step 604: The computer device controls the multiple vehicle controllers to perform the receiving operation of the test message.

[0173] In some embodiments, this step is the same as step 204, which will not be repeated here.

[0174] Step 605: The computer device determines the vehicle controller that receives the test message, and determines the associated vehicle controller of the test message as the vehicle controller that sends the test message and the vehicle controller that receives the test message, which indicates the transceiving relationship between the multiple vehicle controllers.

[0175] In some embodiments, this step is the same as step 205, which will not be repeated here.

[0176] Step 606: The computer device determines the vehicle model information of the vehicle to which the associated vehicle controller of the test message is applied.

[0177] In some embodiments, this step is the same as step 206, which will not be repeated here.

[0178] Step 607: The computer device determines the network segment to which the test message belongs.

[0179] In some embodiments, this step is the same as step 207, which will not be repeated here.

[0180] Step 608: The computer device stores the related information of the test message, the associated vehicle controller of the test message, the vehicle model information of the vehicle to which the associated vehicle controller is applied, and the network segment to which the test message belongs as a record item in the signal library.

[0181] In some embodiments, this step is the same as step 208, which will not be repeated here.

[0182] Step 609: The computer device receives a third query instruction, and the third query instruction carries a target network segment.

[0183] In a possible implementation, the signal library stores the information of the test message in the form of an Excel table, and the table header of the Excel table has a query function; in this step, the target network segment is filtered through the table header of the Excel table to trigger the third query instruction to the computer device.

[0184] Step 610: The computer device determines, based on the target network segment, a plurality of third vehicle controllers belonging to the target network segment from the signal library.

[0185] In the embodiment of the present application, the computer device defines the network segment as an independent node and stores it in the signal library to distinguish different network segments, so that the vehicle controllers of each network segment can be intuitively seen.

[0186] Step 611: The computer device determines, based on the plurality of third vehicle controllers, test messages sent and received by the plurality of third vehicle controllers.

[0187] The signal library stores the controller identifiers of the plurality of third vehicle controllers, and in this step, the computer device determines the record items where the controller identifiers of the plurality of third vehicle controllers are respectively located, and determines the test messages sent and received by the plurality of third vehicle controllers from the record items where the controller identifiers of the plurality of third vehicle controllers are respectively located.

[0188] Step 612: The computer device determines, based on the test messages sent and received by the plurality of third vehicle controllers, the load rate and the delay rate of the target network segment.

[0189] For each third vehicle controller, the computer device determines the load rate and the delay rate of the third vehicle controller based on the test messages sent and received by the third vehicle controller, and determines the load rate and the delay rate of the target network segment based on the load rates and the delay rates of the plurality of third vehicle controllers. For example, the computer device determines the average value of the load rates of the plurality of third vehicle controllers to obtain the load rate of the target network segment, and determines the average value of the delay rates of the plurality of third vehicle controllers to obtain the delay rate of the target network segment.

[0190] In a possible implementation, the step of determining, by the computer device, the load rate and the delay rate of the third vehicle controller based on the test messages sent and received by the third vehicle controller can be: determining, by the computer device, the message length of the test message sent and received by the third vehicle controller to determine the load rate of the third vehicle controller; and determining, by the computer device, the message delay time of the third vehicle controller to determine the delay rate of the third vehicle controller.

[0191] Step 613: The computer device determines whether the target network segment meets the design requirement information based on the load rate and the delay rate of the target network segment.

[0192] The computer device determines whether the load rate of the target network segment is less than a preset load rate and whether the delay rate is less than a preset delay rate; in a case where the load rate of the target network segment is less than the preset load rate and the delay rate is less than the preset delay rate, it is determined that the target network segment meets the design requirement information; in a case where the load rate of the target network segment is not less than the preset load rate or the delay rate is not less than the preset delay rate, it is determined that the target network segment does not meet the design requirement information.

[0193] Step 614: In a case where the target network segment does not meet the design requirement information, the computer device adjusts the test message transmitted and received by the plurality of third vehicle controllers.

[0194] The step of adjusting the test message transmitted and received by the third vehicle controller by the computer device can be: the computer device adjusts at least one of the message type, the message length, the message sending type, the message period, the fast period of message sending, the number of times of fast sending of the message and the message delay time of the test message transmitted and received by the third vehicle controller, and then determines again whether the target network segment meets the design requirement information based on the adjusted test message of the third vehicle controller, adjusts the test message transmitted and received by the third vehicle controller again in a case where the target network segment does not meet the design requirement information, until the target network segment meets the design requirement information.

[0195] In the embodiments of the present application, the load rate and the delay rate of the target network segment can be quickly counted, and the load rate and the delay rate of the target network segment are counted by the third vehicle controller between the target network segments, which guides the network design in the test message design, avoids the change in the later period caused by the design error in the early period, and improves the efficiency.
