[0041] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0043] In order to solve the problem of illegal startup of EOL test of automobile parts due to password loss in the prior art, the embodiment of the present application provides a method, system, device and vehicle for entering EOL test of parts, which can receive the first secret key and secret key seed sent by the lower computer, and then can generate the second secret key based on the secret key seed and the preset secret key generation algorithm, and when the first secret key and the second secret key are consistent, that is, when the secret key verification is successful, the startup mode of the lower computer can be switched from the first mode to the second mode. Since the second mode can be the EOL mode, the lower computer can be controlled to enter the EOL mode by responding to the user's restart command, so as to perform EOL test on the parts. In this way, the secret key can be transmitted through the communication between the upper computer and the lower computer, and the secret key can be securely verified, which ensures the normal communication between the upper computer and the lower computer, thereby improving the security of EOL test of automobile parts.

[0044] The method for entering component EOL testing provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments.

[0045] Figure 1 It is a flowchart of a method for entering component EOL testing provided in an embodiment of the present application.

[0046] like Figure 1 As shown, the execution subject of the method for entering the component EOL test may be a host computer, and the method may include the following steps:

[0047] S110, sending the first secret key to the subordinate computer.

[0048] In some embodiments, the first secret key involved above is generated based on the secret key seed sent by the lower computer and the preset secret key generation algorithm. Among them, the preset secret key algorithm is an algorithm preset by actual experience or situation, and is not limited too much here. The secret key seed involved above can be a random number, and is not limited too much here.

[0049] S120, receiving a first instruction sent by the lower computer.

[0050] In some embodiments, the first instruction involved above indicates that the first key is consistent with the second key, and the second key may be generated by the lower computer based on the key seed and a preset key generation algorithm.

[0051] Specifically, after receiving the first secret key sent by the upper computer, the lower computer can compare the received first secret key with the second secret key generated by itself to see if they are consistent. If the first secret key and the second secret key involved above are consistent, the lower computer can send a first instruction to the upper computer. In this way, the upper computer can receive the first instruction sent by the lower computer so as to subsequently instruct the lower computer to modify the startup mode.

[0052] It should be noted that the lower computer may generate the second key based on the key seed and the preset key generation algorithm after receiving the first key sent by the upper computer, or may generate the second key based on the key seed and the preset key generation algorithm before sending the key seed to the upper computer. The above sequence is not limited too much here.

[0053] S130, sending a second instruction to the lower computer, so that the lower computer switches the startup mode of the lower computer from the first mode to the second mode based on the second instruction.

[0054] The first mode mentioned above may be a Normal mode, that is, a normal mode. The second mode includes a terminal EOL mode.

[0055] Specifically, after the upper computer receives the first instruction sent by the lower computer, since the first instruction can represent that the first key and the second key are consistent, based on this, the upper computer can send a second instruction to the lower computer, and the second instruction is used to modify the startup mode of the lower computer. That is, after receiving the second instruction, the lower computer can switch the startup mode of the lower computer from the first mode to the second mode based on the second instruction, that is, change the Normal mode to the EOL mode.

[0056] In an example, when the first key is consistent with the second key, the upper computer can send a second instruction to the lower computer through diagnosis, so that the lower computer sets the ro.boot.hu.boot.mode attribute in the laconfig partition of the lower computer from the Normal mode to the EOL mode based on the second instruction.

[0057] S140, in response to a restart instruction from the user, controlling the lower computer to enter an EOL mode.

[0058] The restart instruction mentioned above may be an instruction generated in response to a user inputting a power-off button of a relay, which is not specifically limited here.

[0059] Specifically, after the upper computer switches the startup mode of the lower computer from the first mode to the second mode, the upper computer may receive a restart instruction from the user, and in response to the restart instruction, control the lower computer to enter the EOL mode to implement EOL testing of components.

[0060] In an embodiment of the present application, a first secret key can be sent to a lower computer. Since the first secret key is generated by the upper computer based on the secret key seed sent by the lower computer and the preset secret key generation algorithm, and the second secret key is generated by the lower computer based on the secret key seed and the preset secret key generation algorithm, it is convenient for the subsequent lower computer to compare whether the first secret key and the second secret key are consistent. Then, by receiving the first instruction sent by the lower computer, since the first instruction indicates that the first secret key is consistent with the second secret key, based on this, a second instruction can be sent to the lower computer, so that the lower computer switches the startup mode of the lower computer from the first mode to the second mode based on the second instruction. In this way, the secret key can be transmitted through the communication between the upper computer and the lower computer, and the secret key can be securely verified, which ensures the normal communication between the upper computer and the lower computer, thereby improving the security of the EOL test of automotive parts.

[0061] In order to more comprehensively describe the method for entering the component EOL test provided by the embodiment of the present application, in one embodiment, before sending the first secret key to the lower computer, the method for entering the component EOL test involved above may further include the following steps:

[0062] In response to a user's start instruction, a session establishment request is sent to the lower computer, so that the lower computer establishes a session with the upper computer based on the session establishment request;

[0063] Based on the established session, a first request is sent to the lower computer, where the first request is used to request the upper computer to generate a key seed corresponding to the first key.

[0064] The start instruction may include but is not limited to related instructions generated based on user input such as click input, touch input, and sliding input of the start button.

[0065] Specifically, before receiving the first secret key sent to the subordinate computer, the upper computer can receive the user's startup instruction and, in response to the user's startup instruction, send a session establishment request to the subordinate computer, so that the subordinate computer establishes a session with the upper computer based on the session establishment request, and then can send a first request to the subordinate computer based on the established session, and the first request is used to request the upper computer to generate a secret key seed corresponding to the first secret key.

[0066] In this embodiment, a session can be established between the upper computer and the lower computer, and the secret key can be transmitted through communication between the upper computer and the lower computer, and the secret key can be verified, thereby improving the security of the EOL test of automobile parts.

[0067] In order to more accurately describe the method for entering the component EOL test provided by the embodiment of the present application, in one embodiment, the above-mentioned step of controlling the lower computer to enter the EOL mode in response to the user's restart instruction may include the following steps:

[0068] In response to a restart instruction from a user, a file corresponding to the EOL mode is loaded, so as to control the lower computer to enter the EOL mode according to the file.

[0069] Among them, the above-mentioned documents are the relevant documents required for EOL testing of parts and components, which will not be elaborated here.

[0070] Specifically, the upper computer can receive a user's restart command, and in response to the user's restart command, load the file corresponding to the EOL mode. Since the file is a related file required for EOL testing of components, the lower computer can be controlled to enter the EOL mode according to the file corresponding to the EOL mode to implement EOL testing of components.

[0071] In one example, when the host computer responds to the user's restart command, different rc files can be loaded according to the value of ro.boot.hu.boot.mode prop. For example, if the current boot mode of the lower computer is EOL mode, the file corresponding to the EOL mode, i.e., the init.liammi.rc file, needs to be loaded. If the boot mode of the lower computer is Normal mode at this time, the file corresponding to the Normal mode, i.e., the init.rc file, needs to be loaded.

[0072] In this embodiment, by responding to the user's restart instruction, the file corresponding to the EOL mode can be loaded, and the lower computer can be controlled to enter the EOL mode according to the file corresponding to the EOL mode. In this way, after the boot.mode attribute of the lower computer is set to the EOL mode, it is realized that the computer automatically enters the EOL mode when it is powered on in the parts factory.

[0073] In order to more comprehensively describe the method for entering the EOL test of a component provided by an embodiment of the present application, in one embodiment, after responding to a user's restart instruction and controlling the lower computer to enter the EOL mode so as to perform the EOL test on the component, the method for entering the EOL test of the component involved may further include the following steps:

[0074] In response to the end instruction of performing EOL test on the component, a third instruction is sent to the subordinate computer, so that the subordinate computer changes the startup mode of the subordinate computer from the second mode to the first mode based on the third instruction.

[0075] Specifically, after controlling the lower computer to enter the EOL mode, the upper computer can send a third instruction to the lower computer in response to the end instruction of the EOL test on the component, so that after receiving the third instruction, the lower computer can change the startup mode of the lower computer from the second mode to the first mode based on the third instruction. That is, after the EOL test on the component is completed, the upper computer can change the startup mode of the lower computer from the EOL mode to the Normal mode.

[0076] In this embodiment, it is possible to respond to the end instruction of the EOL test on the component, that is, after the test on the component is completed, by sending a third instruction to the lower computer, so that the lower computer can change the startup mode of the lower computer from the second mode to the first mode based on the third instruction. In this way, after the last process test is completed, the upper computer can switch to the Normal mode, and there is no need to enter the EOL mode separately when testing each process, which speeds up the startup time and saves testing time.

[0077] In order to more accurately and comprehensively describe the component EOL test method provided in the embodiment of the present application, in one embodiment, the above-mentioned step of sending the second instruction to the lower computer so that the lower computer switches the startup mode of the lower computer from the first mode to the second mode based on the second instruction may specifically include the following steps:

[0078] A second instruction is sent to the lower computer, wherein the second instruction includes a mode switching parameter, so that the lower computer calls the first interface to transfer the mode switching parameter to the second interface, and obtains the mode switching parameter based on the second interface to switch the startup mode of the lower computer from the first mode to the second mode.

[0079] Among them, the above-mentioned mode switching parameters can be used to switch the startup mode of the lower machine from the first mode to the relevant parameters of the second mode, which will not be repeated here. In addition, the above-mentioned first interface can be an interface at the service layer of the lower machine, and the second interface can be an interface at the kernel layer of the lower machine.

[0080] Specifically, the upper computer can send a second instruction to the lower computer. Since the second instruction may include a mode switching parameter, the lower computer can subsequently call the first interface to pass the mode switching parameter to the second interface, and obtain the mode switching parameter based on the second interface to switch the startup mode of the lower computer from the first mode to the second mode.

[0081] In this embodiment, by sending a second instruction to the lower computer, the lower computer can call the first interface to pass the mode switching parameters included in the second instruction to the second interface, thereby facilitating the second interface to obtain the mode switching parameters and switch the startup mode of the lower computer from the first mode to the second mode, thereby realizing the switching of the startup mode of the lower computer.

[0082] In addition, the embodiment of the present application also provides another method for entering component EOL testing.

[0083] like Figure 2 As shown, the execution subject of the method may be a lower computer, and the method may specifically include the following steps:

[0084] S210, receiving a first secret key sent by a host computer.

[0085] In some embodiments, the first secret key involved above is generated by the upper computer based on the secret key seed sent by the lower computer and the preset secret key generation algorithm. Among them, the preset secret key algorithm is an algorithm preset by actual experience or situation, and is not limited too much here. The secret key seed involved above can be a random number, and is not limited too much here.

[0086] S220, obtaining a second secret key.

[0087] In some embodiments, the second secret key mentioned above is generated by the lower computer based on a secret key seed and a preset secret key generation algorithm.

[0088] Specifically, in one embodiment, the above-mentioned step of obtaining the second secret key may include the following steps:

[0089] Get the secret key seed;

[0090] The second secret key is generated by inputting the secret key seed into a preset secret key generation algorithm.

[0091] S230: When the first secret key and the second secret key are consistent, send a first instruction to the host computer.

[0092] Specifically, after receiving the first key sent by the upper computer and obtaining the second key, the lower computer can first compare whether the first key and the second key are consistent. If they are consistent, a first instruction is sent to the upper computer to facilitate subsequent operations of the upper computer.

[0093] S240, receiving a second instruction sent by the host computer.

[0094] Specifically, after the lower computer sends the first instruction to the upper computer, since the first instruction can indicate that the first secret key generated by the upper computer is consistent with the second secret key generated by the lower computer, that is, the communication between the upper computer and the lower computer is normal, the upper computer can send the second instruction to the lower computer. Based on this, the lower computer can receive the second instruction sent by the upper computer.

[0095] S250, based on the second instruction, switching the startup mode of the lower computer from the first mode to the second mode, where the second mode includes the terminal EOL mode, so that the upper computer controls the lower computer to enter the EOL mode in response to the user's restart instruction.

[0096] Specifically, after receiving the second instruction, the lower computer can switch the startup mode of the lower computer from the first mode to the second mode based on the second instruction, that is, change the Normal mode to the EOL mode, so that the upper computer can subsequently respond to the user's restart instruction and control the lower computer to enter the EOL mode.

[0097] In the embodiment of the present application, the first secret key sent by the host computer can be received, and the second secret key can be obtained. Since the first secret key is generated by the host computer based on the secret key seed sent by the slave computer and the preset secret key algorithm, and the second secret key is generated by the slave computer based on the secret key seed and the preset secret key generation algorithm, based on this, when the first secret key and the second secret key are consistent, the first instruction sent to the host computer can then receive the second instruction sent by the host computer, and then based on the second instruction, the startup mode of the slave computer can be switched from the first mode to the second mode. In this way, the secret key can be transmitted through the communication between the host computer and the slave computer, and the secret key can be securely verified, which ensures the normal communication between the host computer and the slave computer, thereby improving the security of the EOL test of automotive parts.

[0098] In order to more accurately describe the method for EOL testing of components provided in the embodiment of the present application, in one embodiment, the above-mentioned S250 may include the following steps:

[0099] receiving a second instruction sent by the host computer, where the second instruction includes a mode switching parameter;

[0100] The first interface is called to transfer the mode switching parameter to the second interface, and the mode switching parameter is obtained based on the second interface to switch the startup mode of the lower computer from the first mode to the second mode.

[0101] Among them, the above-mentioned mode switching parameters can be used to switch the startup mode of the lower machine from the first mode to the relevant parameters of the second mode, which will not be described in detail here. In addition, the above-mentioned first interface can be an interface at the service layer of the lower machine, and the second interface can be an interface at the kernel layer of the lower machine.

[0102] In this embodiment, by receiving the second instruction sent by the upper computer, since the second instruction may include a mode switching parameter, based on this, the lower computer can call the first interface to transfer the mode switching parameter value to the second interface, and can obtain the mode switching parameter based on the second interface, and switch the startup mode of the lower computer from the first mode to the second mode. In this way, the switching of the startup mode of the lower computer is realized.

[0103] It should be noted that the embodiment of the present application also provides a system for entering the EOL test of components, such as Figure 3As shown, the system for entering the component EOL test may include an upper computer and a lower computer, wherein the upper computer and the lower computer are communicatively connected.

[0104] Based on this, the embodiment of the present application also provides an interaction process between the upper computer and the lower computer, which can be specifically as follows: Figure 3 As shown, the process may specifically include the following steps:

[0105] S301, the upper computer sends a first secret key to the lower computer.

[0106] Specifically, the upper computer may send a first secret key to the lower computer, wherein the first secret key is generated based on a secret key seed sent by the lower computer and a preset secret key generation algorithm.

[0107] S302, the lower computer obtains the second secret key.

[0108] Specifically, the lower computer can obtain the second key before receiving the first key sent by the upper computer, after receiving the first key sent by the upper computer, or at the same time as the lower computer receives the first key sent by the upper computer. The second key is generated by the lower computer based on the key seed and the preset key generation algorithm.

[0109] S303, the lower computer compares whether the first secret key and the second secret key are consistent.

[0110] Specifically, after receiving the first secret key sent by the upper computer and obtaining the second secret key, the lower computer may first compare whether the first secret key and the second secret key are consistent.

[0111] S304: When the first secret key and the second secret key are consistent, the lower computer sends a first instruction to the upper computer.

[0112] Specifically, during the process of comparing whether the first secret key and the second secret key are consistent, if the first secret key and the second secret key are consistent, the lower computer can send a first instruction to the upper computer. The first instruction indicates that the first secret key and the second secret key are consistent;

[0113] S305: The upper computer sends a second instruction to the lower computer.

[0114] Specifically, after the upper computer receives the first instruction sent by the lower computer, since the first instruction indicates that the first key and the second key are consistent, the upper computer can send the second instruction to the lower computer.

[0115] S306: The lower computer switches the startup mode of the lower computer from the first mode to the second mode based on the second instruction.

[0116] Specifically, after receiving the second instruction, the lower computer may switch the startup mode of the lower computer from the first mode to the second mode based on the second instruction. The second mode includes the terminal EOL mode;

[0117] S307, the host computer receives a restart instruction from the user.

[0118] S308: The upper computer controls the lower computer to enter EOL mode in response to the user's restart instruction.

[0119] It should be noted that the interactive processing process between the upper computer and the lower computer can refer to all the above-mentioned embodiments of the method for entering the component EOL test.

[0120] In an embodiment of the present application, after the upper computer sends the first secret key to the lower computer and the lower computer obtains the second secret key, since the first secret key is generated by the upper computer based on the secret key seed sent by the lower computer and the preset secret key generation algorithm, and the second secret key is generated by the lower computer based on the secret key seed and the preset secret key generation algorithm, based on this, the lower computer can compare whether the first secret key and the second secret key are consistent, and send a first instruction to the upper computer when the first secret key and the second secret key are consistent. Since the first instruction represents that the first secret key and the second secret key are consistent, the upper computer can send a second instruction to the lower computer so that the lower computer can switch the startup mode of the lower computer from the first mode to the second mode based on the second instruction, and then when the upper computer receives the user's restart instruction, it can respond to the user's restart instruction and control the lower computer to enter the EOL mode. In this way, the secret key can be transmitted through the communication between the upper computer and the lower computer, and the secret key can be securely verified, thereby ensuring normal communication between the upper computer and the lower computer, thereby improving the security of the EOL test of automotive parts.

[0121] It should be noted that the method for entering the EOL test of components provided in the embodiment of the present application can increase the information security of the vehicle computer, facilitate after-sales return testing, facilitate rework of components in the component factory, increase the flexibility of product testing, and during normal testing, only load the test software through the EOL mode, thereby improving test efficiency and software stability.

[0122] Based on the same inventive concept, the embodiment of the present application also provides a device for entering the EOL test of a component. The device for entering the EOL test of a component can be applied to a host computer, and can be specifically combined with Figure 4 The device for entering component EOL testing provided in the embodiment of the present application is described in detail.

[0123] Figure 4 It is a structural schematic diagram of a device for entering component EOL testing provided in an embodiment of the present application.

[0124] like Figure 2As shown, the device 400 for component EOL testing may include: a sending module 410 , a receiving module 420 and a control module 430 .

[0125] A sending module 410 is used to send a first secret key to a lower computer, where the first secret key is generated based on a secret key seed sent by the lower computer and a preset secret key generation algorithm;

[0126] A receiving module 420 is used to receive a first instruction sent by a lower computer, where the first instruction indicates that the first key is consistent with the second key, and the second key is generated by the lower computer based on a key seed and a preset key generation algorithm;

[0127] The sending module 410 is further used to send a second instruction to the lower computer when the first secret key is consistent with the second secret key, so that the lower computer switches the startup mode of the lower computer from the first mode to the second mode based on the second instruction, and the second mode includes the terminal end-of-line (EOL) mode;

[0128] The control module 430 is used to control the lower computer to enter the EOL mode in response to a restart instruction from the user.

[0129] In one embodiment, the sending module mentioned above is used to send a session establishment request to the subordinate computer in response to a user's start instruction before sending the first secret key to the subordinate computer, so that the subordinate computer establishes a session with the upper computer based on the session establishment request;

[0130] The sending module is also used to send a first request to the lower computer based on the established session, where the first request is used to request the upper computer to generate a key seed corresponding to the first key.

[0131] In one embodiment, the control module mentioned above is specifically used for:

[0132] In response to the user's restart instruction, the file corresponding to the EOL mode is loaded, and according to the file, the lower computer is controlled to enter the EOL mode, and the file is a related file required for the EOL test of the component.

[0133] In one embodiment, the sending module involved above is also used to send a third instruction to the lower computer in response to an end instruction of the EOL test on the component after controlling the lower computer to enter the EOL mode in response to a restart instruction of the user, so that the lower computer switches the startup mode of the lower computer from the second mode to the first mode based on the third instruction.

[0134] In one embodiment, the sending module involved above is specifically used for: the lower computer sends a second instruction, the second instruction includes a mode switching parameter, so that the lower computer calls the first interface to pass the mode switching parameter to the second interface, and obtains the mode switching parameter based on the second interface to switch the startup mode of the lower computer from the first mode to the second mode.

[0135] In the embodiment of the present application, the first secret key can be sent to the lower computer. Since the first secret key is generated based on the secret key seed sent by the lower computer and the preset secret key generation algorithm, the lower computer can compare whether the first secret key and the second secret key are consistent, and then can receive the first instruction sent by the lower computer. Since the first instruction indicates that the first secret key is consistent with the second secret key, the second instruction can be sent to the lower computer, so that the lower computer switches the startup mode of the lower computer from the first mode to the second mode based on the second instruction. In this way, the secret key can be transmitted through the communication between the upper computer and the lower computer, and the secret key can be securely verified, which ensures the normal communication between the upper computer and the lower computer, thereby improving the security of the EOL test of automotive parts.

[0136] Each module in the device for entering the EOL test of components provided in the embodiment of the present application can be realized Figure 1 The method steps of the illustrated embodiment can achieve the corresponding technical effects, and for the sake of brevity, they will not be repeated here.

[0137] Based on the same inventive concept, the embodiment of the present application also provides a device for entering the EOL test of a component. The device for entering the EOL test of a component can be applied to a lower computer, and can be specifically combined with Figure 5 The device for entering component EOL testing provided in the embodiment of the present application is described in detail.

[0138] Figure 5 It is a structural schematic diagram of a device for entering component EOL testing provided in an embodiment of the present application.

[0139] like Figure 5 As shown, the device 500 for component EOL testing may include a receiving module 510 , an acquiring module 520 , a sending module 530 and a switching module 540 .

[0140] The receiving module 510 is used to receive a first secret key sent by the upper computer, where the first secret key is generated by the upper computer based on a secret key seed sent by the lower computer and a preset secret key generation algorithm;

[0141] An acquisition module 520 is used to acquire a second secret key, where the second secret key is generated by the lower computer based on a secret key seed and a preset secret key generation algorithm;

[0142] A sending module 530, configured to send a first instruction to an upper computer when the first key and the second key are consistent;

[0143] The receiving module 510 is further used to receive a second instruction sent by the host computer;

[0144] The switching module 540 is used to switch the startup mode of the lower computer from the first mode to the second mode based on the second instruction, wherein the second mode includes the terminal EOL mode, so that the upper computer controls the lower computer to enter the EOL mode in response to the user's restart instruction.

[0145] In one embodiment, the switching module mentioned above is specifically used to: receive a second instruction sent by a host computer, where the second instruction includes a mode switching parameter;

[0146] The first interface is called to transfer the mode switching parameter to the second interface, and the mode switching parameter is obtained based on the second interface to switch the startup mode of the lower computer from the first mode to the second mode.

[0147] In the embodiment of the present application, the first secret key sent by the host computer can be received, and the second secret key can be obtained. Since the first secret key is generated by the host computer based on the secret key seed sent by the slave computer and the preset secret key algorithm, and the second secret key is generated by the slave computer based on the secret key seed and the preset secret key generation algorithm, based on this, when the first secret key and the second secret key are consistent, the first instruction sent to the host computer can then receive the second instruction sent by the host computer, and then based on the second instruction, the startup mode of the slave computer can be switched from the first mode to the second mode. In this way, the secret key can be transmitted through the communication between the host computer and the slave computer, and the secret key can be securely verified, which ensures the normal communication between the host computer and the slave computer, thereby improving the security of the EOL test of automotive parts.
