[0038] Please refer to Figure 1 , Figure 1 is one of the flowcharts of the ADAS and BMS key learning test method provided by the embodiments of the present application, as shown in Figure 1 , the method comprises:

[0039] Step 101, based on the message simulation of the sending logic of the host computer to the ADAS, the environment model file of the key learning test is obtained, and the environment model file includes the SKC and the SC.

[0040] Specifically, based on the message simulation of the sending logic of the host computer to the ADAS, the sending logic of the SKC, the SC, the random number and the like after the ADAS sends a request to learn the state in the environment model can be simulated, which can be realized in MATLAB / SIMULINK2018, and the implementation logic is explained. The host computer can be a computer or a single-chip microcomputer that directly sends operation instructions. Generally, it provides a user operation interactive interface and shows feedback data to the user. The ADAS can be an advanced driving assistance system (ADAS). The environment model file can be an environment model obtained after simulating the ADAS. The SKC can be a secret key code (SKC). The SC can be a safe code (SC). The SKC and the SC can be generated by a vehicle identification number (VIN) and have uniqueness, and are composed of 16 bytes and 3 bytes respectively.

[0041] Step 102, based on the host computer, the environment model file is compiled in the HIL device.

[0042] Specifically, the HIL device can be a hardware-in-the-loop (HIL) device. Hardware-in-the-loop is a development and testing technology for complex device controllers.

[0043] Step 103, the host computer generates an executable file according to the environment model file.

[0044] Specifically, the executable file is a file that can be directly executed by an autonomous automatic test tool, which can be a test case. The test case can be designed according to the simulation logic and implementation logic description, and specific scenarios and parameters are designed to verify the function and performance of the system. For example, Table 1 below is a BMS key learning test case. As shown in Table 1, the input signal of this test case is the external interface of the environment model, and the learning flow logic is integrated inside the model. Before learning, the ADAS sends a "request learning state" signal, and the BMS feedbacks the learning state "not learned". After learning (this process is completed in the "S5" row of the test case), the "request learning state" signal is sent again, and the BMS feedbacks the learning state "has learned". The specific learning process is as shown in Figure 2 and Figure 3 , wherein the contents in the dashed box are integrated inside the environment.

[0045] Table 1 BMS key learning test case

[0046]

[0047] Table 2 below is a BMS clear learning state test case. As shown in Table 2, the input signal of this test case is the external interface of the environment model. Before clearing the learning state, it is ensured that the BMS is in the "has learned" state. After clearing the learning state, the learning state is requested again. If the BMS learning state returns "not learned", it indicates that the clearing is successful.

[0049]

[0050]

[0051] Step 104, based on the host computer, the executable file is sent to the HIL device.

[0052] Step 105, based on the HIL device, the executable file is used to perform a key learning test on the battery management system BMS.

[0053] Specifically, the battery management system BMS can be a battery management system (BMS), the key learning test includes a learning process and a clearing process, the learning processes of the BMS in the factory mode and the after-sales mode are different, in the offline learning function, the BMS writes SKC and SC into a secure storage area through a Tester device, and checks through an authentication process between ADAS and the BMS, after the checking, the offline learning function ends; in the after-sales learning process, the newly installed BMS shares the stored SKC and SC in the ADAS with the newly installed BMS through the Tester sending instructions, and checks through the authentication process between the ADAS and the BMS, after the checking, the after-sales learning process ends, wherein the Tester device in the factory learning mode refers to an offline electrical inspection device, the Tester device in the after-sales mode refers to an after-sales diagnostic instrument, and the secure storage area can be stored into a secure chip with a hardware secure chip or into a FLASH memory without the hardware secure chip.

[0054] In the embodiment of the application, the key learning test method can simulate the communication process of ADAS and BMS on the HIL test environment, so that the BMS bus communication security algorithm becomes a testable item in the HIL environment, ensuring the security of bus communication, and through writing use cases and automatic scripts, automatic testing is realized, so that the accuracy of the test is higher.

[0055] Optionally, the sending logic of the auxiliary driving system ADAS based on the host computer is packet simulated to obtain an environment model file of the key learning test, including:

[0056] The sending logic of the learning process of the auxiliary driving system ADAS based on the host computer is packet simulated to obtain a learning environment model file in the key learning test;

[0057] The sending logic of the clearing process of the auxiliary driving system ADAS based on the host computer is packet simulated to obtain a clearing environment model file in the key learning test, and the environment model file includes the learning environment model file and the clearing environment model file.

[0058] Specifically, the key learning of the ADAS and the BMS includes a key learning process and a clearing process, for example, Figure 4 is a flow chart of the key learning process of the ADAS and the BMS provided by the embodiment of the application, as Figure 4As shown, the ADAS sends a system learning activation to start the learning process, and the BMS receives the signal and feeds back its learning state. If the BMS is in the learned state, the BMS does not perform the learning process. If the BMS is in the unlearned state, the BMS starts the learning process, and the ADAS continues to send the SKC and SC, which are stored in the BMS in the safe area. Then, the BMS verifies the SKC and SC through the random number. If the authentication fails and times out, the ADAS sends an authentication failure. If the authentication is passed, the BMS stops the learning process, and the ADAS sends a learning state setting. After receiving the signal, the BMS sets its learning state to the learned state and sends its learning state.

[0059] Figure 5 FIG. 1 is a flowchart of a key learning process of an ADAS and a BMS according to an embodiment of the present application. Figure 5 As shown, when the ADAS sends a learning instruction and SC, the BMS compares the SC value with the stored value. If the values are inconsistent, the BMS does not execute the clearing command. If the values are consistent, the BMS clears the learning state.

[0060] In the embodiment of the present application, the test method for key learning can simulate the key learning process and the clearing process of the ADAS and the BMS, respectively, to obtain the learning environment model file and the clearing environment model file, thereby realizing automatic testing of the key learning process and the clearing process of the ADAS and the BMS.

[0061] Optionally, the learning environment model file in the key learning test is obtained by packet simulation based on the sending logic of the learning process of the auxiliary driving system ADAS.

[0062] In the case where the ADAS sends a request learning state signal to the BMS, the learning state replied by the BMS is received.

[0063] In the case where the replied learning state is unlearned, the ADAS sends a key SKC and a security code SC to the BMS every first time interval.

[0064] In the case where the SKC and SC are sent, the ADAS waits for a second time interval, and then sends a random number packet to the BMS. The second time interval is greater than the first time interval.

[0065] The ADAS compares the calculation result sent by the BMS and the random number packet to obtain an authentication result. The calculation result is obtained by the BMS according to the received random number packet, and the authentication result is used to indicate whether the BMS learns successfully.

[0066] In a case that the authentication result represents that the BMS learns successfully, the ADAS sends the authentication result to the BMS;

[0067] In a case that the authentication result is sent, the ADAS sends setting learning state information to the BMS, the setting learning state information being used for instructing the BMS to set a learning state.

[0068] Specifically, the ADAS learning flow message simulation is crucial in terms of when to send and signal values sent, for example, Figure 6 The flow chart of ADAS learning flow message simulation is as shown in Figure 6 As shown, the ADAS learning message (message 1) polls to send a request learning state, an SKC and an SC, and when the setting request learning state signal is 1, the SKC and the SC are continuously sent, the time interval is 30 ms, after the sending is completed, 100 ms is waited to trigger the sending of a random number message, the message (message 2) also polls to send a random number and an authentication result, and after the AES calculation result returned by the BMS is compared, an authentication success is output, and after the authentication success is sent, the message 1 sends setting learning state.

[0069] In the embodiment of the present application, the key learning test method can simulate the key learning process of the BMS by using an automatic test tool, verify the correctness and security of the key learning process, improve the test efficiency and quality, and reduce the errors and costs of manual operation.

[0070] Optionally, the sending logic of the clearing flow of the auxiliary driving system ADAS based on the host computer is simulated by a message to obtain a clearing environment model file in the key learning test, and the clearing environment model file comprises:

[0071] The ADAS sends a clearing learning instruction and a security code SC to the BMS, wherein the clearing learning instruction is used for instructing the BMS to clear a learning state.

[0072] In a case that the security code SC is the same as the security code stored by the BMS, the BMS executes the clearing learning instruction.

[0073] Specifically, the flow of the ADAS learning flow message simulation is that the ADAS learning message (message 3) sends a clearing instruction and an SC code to the BMS.

[0074] In the embodiment of the present application, the key learning test method can simulate the key clearing process of the BMS by using an automatic test tool, verify the correctness and security of the key clearing process, improve the test efficiency and quality, and reduce the errors and costs of manual operation.
