[0028] Example 1

[0029] According to an embodiment of the present invention, a method for determining the mode of a vehicle system is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0030] Figure 1 This is a flowchart of a method for determining the mode of a vehicle infotainment system according to an embodiment of the present invention. The method can be applied to a vehicle infotainment system and may include the following steps:

[0031] Step S101: Respond to the input command applied to the interactive interface of the vehicle system and obtain the initial password of the vehicle system.

[0032] In the technical solution provided in step S101 of the present invention, the interactive interface can be used to at least represent a password input interface. The initial password can be obtained by encrypting the first key of the vehicle system and the vehicle identification code stored in the cloud. Wireless communication can be maintained between the cloud and the vehicle system. The initial password can be an engineering mode password obtained from the cloud, the first key can be the master key of the vehicle model obtained from the cloud, and the identification code can be the Vehicle Identification Number (VIN). This is only an example and not a specific limitation.

[0033] In this embodiment, the initial password of the vehicle's infotainment system is obtained in response to an input command applied to the system's interactive interface. Optionally, in this embodiment, when an input command is issued to the vehicle's interactive interface, the initial password obtained from the cloud is entered on the interface to obtain the entered initial password. For example, when an input command is issued to the password input interface, an engineering mode password obtained from the cloud platform is entered on the password input interface to obtain the entered engineering mode password. The engineering mode password can be obtained by encrypting the vehicle model's master key and the vehicle's VIN code stored on the cloud platform; this is merely an example and not a specific limitation.

[0034] Step S102: Based on the initial password and identification code, determine the second key stored in the vehicle system.

[0035] In the technical solution provided by step S102 of the present invention, the second key can be the master key of the vehicle model obtained from the vehicle system, and the storage location of the second key can be different from the storage location of the first key.

[0036] In this embodiment, after receiving an input command from the vehicle's infotainment system's interface and obtaining its initial password, a second key stored in the system is determined based on the initial password and the identification code. Optionally, this embodiment can obtain the vehicle's identification code in addition to the initial password. Based on the vehicle's identification code, the second key stored in the system can be determined. For example, the system can obtain the vehicle's VIN code after receiving the engineering mode password sent from the cloud. Based on the VIN code, the system can determine the vehicle model's master key from its security module.

[0037] Step S103: Encrypt the second key and the identification code to obtain the target password.

[0038] In the technical solution provided by step S103 of the present invention, the target password can be an engineering mode password obtained from the vehicle system, or the target password can be obtained by encrypting the second key of the vehicle system and the vehicle identification code stored in the vehicle system.

[0039] In this embodiment, after determining the second key stored in the vehicle's infotainment system based on the initial password and the identification code, the second key and the identification code are encrypted to obtain the target password. Optionally, in this embodiment, based on the second key stored in the vehicle's infotainment system, the target key can be determined from a key database. Using the determined target key, the second key and the identification code are encrypted to obtain the target password. The target key can be a symmetric key or an asymmetric key; this is merely an example and not a specific limitation.

[0040] Optionally, based on determining the master key of the vehicle model stored in the vehicle infotainment system, a key filtering operation can be performed in the key database to obtain the target key. Using the filtered target key, the master key of the vehicle model and the vehicle's VIN code stored in the vehicle infotainment system can be encrypted to obtain the target password.

[0041] Optionally, if the determined target key is a symmetric key, then the second key and the identification code can be symmetrically encrypted using the target key to obtain the target password. If the determined target key is an asymmetric key, then the second key and the identification code can be asymmetrically encrypted using the target key to obtain the target password. This is only an example and is not specifically limited.

[0042] Step S104: Based on the initial password and the target password, determine whether the vehicle system has entered engineering mode.

[0043] In the technical solution provided by step S104 of the present invention, the above-mentioned engineering mode can be used to troubleshoot various vehicle problems and debug various vehicle parameters.

[0044] In this embodiment, after encrypting the second key and the identification code to obtain the target password, the vehicle system is determined to have entered engineering mode based on the initial password and the target password. Optionally, this embodiment, based on the encrypted target password, performs detection on the obtained initial password and the obtained target password to obtain a detection result. Based on the relationship between the initial password and the target password as indicated by the detection result, it can be determined whether the vehicle system has entered engineering mode.

[0045] In this embodiment, if the relationship between the initial password and the target password indicated by the detection result is that the initial password and the target password are the same, it can be determined that the vehicle system has entered engineering mode. If the relationship between the initial password and the target password indicated by the detection result is that the initial password and the target password are different, it can be determined that the vehicle system has not entered engineering mode.

[0046] In steps S101 to S104 of this application, when determining the vehicle system's mode, the system can respond to input commands applied to the vehicle system's interactive interface to obtain the vehicle system's initial password. Based on the obtained initial password and identification code, the second key stored in the vehicle system can be determined. Encrypting the determined second key and identification code yields the target password. Based on the obtained initial password and target password, it can be determined whether the vehicle system has entered engineering mode, thereby achieving the goal of avoiding significant threats to vehicle safety, solving the technical problem of low vehicle control security, and realizing the technical effect of improving vehicle control security.

[0047] The method described in this embodiment will be further described below.

[0048] As an optional embodiment, step S102, determining the second key stored in the vehicle system based on the initial password and the identification code, includes: obtaining the identification code in response to the vehicle system receiving the input initial password; and obtaining the second key in response to the vehicle system obtaining the identification code.

[0049] In this embodiment, after obtaining the initial password of the vehicle's infotainment system in response to an input command applied to the system's interactive interface, the system obtains an identification code in response to receiving the initial password; and obtains a second key in response to obtaining the identification code. Optionally, in this embodiment, if the vehicle's infotainment system receives the initial password input from its interactive interface, it can obtain the vehicle's identification code. If the system obtains the vehicle's identification code, it can obtain the second key from the system's security module. For example, if the system receives an engineering mode password input from the password input interface, it can obtain the vehicle's VIN code. If the system obtains the vehicle's VIN code, it can obtain the vehicle model's master key from the system's security module.

[0050] As an optional embodiment, step S104, determining whether the vehicle system has entered engineering mode based on the initial password and the target password, includes: detecting the initial password and the target password to obtain the detection result; and determining whether the vehicle system has entered engineering mode based on the detection result.

[0051] In this embodiment, after encrypting the second key and the identification code to obtain the target password, the initial password and the target password are tested to obtain a test result. Based on the test result, it is determined whether the vehicle system has entered engineering mode. Optionally, this embodiment, based on the encrypted target password, tests the obtained initial password and the obtained target password to obtain a test result. Judging the obtained test result, it can be determined whether the vehicle system has entered engineering mode. If the test result indicates that the initial password and the target password are the same, it can be determined that the vehicle system has entered engineering mode; if the test result indicates that the initial password and the target password are different, it can be determined that the vehicle system has not entered engineering mode.

[0052] Optionally, the engineering mode password obtained from the cloud and the engineering mode password obtained from the vehicle's infotainment system can be tested to obtain a test result. The test result can be used to determine whether the vehicle's infotainment system has entered engineering mode. If the test result shows that the engineering mode password obtained from the cloud is the same as the engineering mode password obtained from the vehicle's infotainment system, then the vehicle's infotainment system has entered engineering mode. If the test result shows that the engineering mode password obtained from the cloud is different from the engineering mode password obtained from the vehicle's infotainment system, then the vehicle's infotainment system has not entered engineering mode.

[0053] As an optional implementation method, determining whether the vehicle system has entered engineering mode based on the detection result includes: determining that the vehicle system has entered engineering mode in response to the detection result that the initial password is the same as the target password; and determining that the vehicle system has not entered engineering mode in response to the detection result that the initial password is different from the target password.

[0054] In this embodiment, after detecting the initial password and the target password and obtaining the detection result, if the detection result is that the initial password and the target password are the same, it is determined that the vehicle system has entered engineering mode; if the detection result is that the initial password and the target password are different, it is determined that the vehicle system has not entered engineering mode. Optionally, this embodiment can determine whether the vehicle system has entered engineering mode by judging the obtained detection result. If it is determined that the obtained detection result is that the initial password and the target password are the same, it can be determined that the vehicle system has entered engineering mode; if it is determined that the obtained detection result is that the initial password and the target password are different, it can be determined that the vehicle system has not entered engineering mode.

[0055] Optionally, the obtained detection results can be evaluated to determine whether the vehicle system has entered engineering mode. If the detection result indicates that the engineering mode password obtained from the cloud is the same as the engineering mode password obtained from the vehicle system, then the vehicle system has entered engineering mode. If the detection result indicates that the engineering mode password obtained from the cloud is different from the engineering mode password obtained from the vehicle system, then the vehicle system has not entered engineering mode.

[0056] As an optional embodiment, step S101, in response to an input command applied to the interactive interface of the vehicle system, obtains the initial password of the vehicle system, including: in response to an input command applied to the interactive interface, inputting the initial password; and obtaining the input initial password.

[0057] In this embodiment, in response to an input command applied to the interactive interface, an initial password is entered; and the entered initial password is then obtained. Optionally, in this embodiment, when an input command is initiated to the vehicle's interactive interface, an initial password obtained from the cloud is entered on the vehicle's interactive interface, thereby obtaining the entered initial password. For example, when an input command is initiated to the password input interface, an engineering mode password obtained from the cloud platform is entered on the password input interface, thereby obtaining the entered engineering mode password. The engineering mode password can be obtained by encrypting the vehicle model's master key and the vehicle's VIN code stored on the cloud platform; this is only an example and not a specific limitation.

[0058] As an optional embodiment, the method further includes: determining a third key for encrypting the first key and the identification code; and using the third key to encrypt the first key and the identification code to obtain an initial password.

[0059] In this embodiment, the third key can be either a symmetric key or an asymmetric key; this is merely an example and not a specific limitation.

[0060] In this embodiment, a third key is determined for encrypting the first key and the identification code; the first key and the identification code are then encrypted using the third key to obtain the initial password. Optionally, this embodiment can obtain the third key by performing a key filtering operation in a key library. The first key and the identification code are then encrypted using the filtered third key to obtain the initial password.

[0061] Optionally, if the third key obtained through screening is a symmetric key, then the first key and the identification code can be symmetrically encrypted using this third key to obtain the initial password. For example, the initial password can be obtained by symmetrically encrypting the vehicle model master key and the vehicle's VIN code obtained from the cloud using this third key.

[0062] Optionally, if the third key obtained through screening is an asymmetric key, then the first key and the identification code can be asymmetrically encrypted using this third key to obtain the initial password. For example, the initial password can be obtained by asymmetrically encrypting the vehicle model master key and the vehicle's VIN code obtained from the cloud using this third key.

[0063] As an optional embodiment, step S103, encrypting the second key and the identification code to obtain the target password, includes: determining a fourth key for encrypting the second key and the identification code; and using the fourth key to encrypt the second key and the identification code to obtain the target password.

[0064] In this embodiment, the fourth key can be either a symmetric key or an asymmetric key. This is only an example and is not a specific limitation.

[0065] In this embodiment, a fourth key is determined for encrypting the second key and the identification code; using the fourth key, the second key and the identification code are encrypted to obtain the target password. Optionally, this embodiment performs a key filtering operation in a key library to obtain the fourth key. Using the filtered fourth key, the second key and the identification code are encrypted to obtain the target password.

[0066] Optionally, if the fourth key obtained through filtering is a symmetric key, then the second key and the identification code can be symmetrically encrypted using this fourth key to obtain the target password. For example, the target password can be obtained by symmetrically encrypting the vehicle model master key and the vehicle's VIN code stored in the vehicle's infotainment system using this fourth key.

[0067] Optionally, if the fourth key obtained through filtering is an asymmetric key, then the second key and the identification code can be asymmetrically encrypted using this fourth key to obtain the target password. For example, the target password can be obtained by asymmetrically encrypting the vehicle model master key and the vehicle's VIN code stored in the vehicle's infotainment system using this fourth key.

[0068] As an optional embodiment, the method further includes: detecting the vehicle's status and / or adjusting the vehicle's parameters in response to the vehicle system entering engineering mode.

[0069] In this embodiment, the above-described detection operation can be used to troubleshoot various vehicle problems, and the above-described adjustment operation can be used to adjust various vehicle parameters.

[0070] In this embodiment, in response to the vehicle's infotainment system entering engineering mode, the vehicle's status is detected, and / or the vehicle's parameters are adjusted. Optionally, this embodiment determines whether the vehicle's infotainment system has entered engineering mode. If it is determined that the vehicle's infotainment system has entered engineering mode, the vehicle's status is detected to investigate the current problem with the vehicle, or the vehicle's parameters are adjusted to correct any abnormal parameters currently present in the vehicle.

[0071] In this embodiment, it is determined whether the vehicle system has entered engineering mode. If it is determined that the vehicle system has entered engineering mode, the vehicle status is detected to investigate the current problems of the vehicle, and the vehicle parameters are adjusted to correct the abnormal parameters of the vehicle.

[0072] In this embodiment, the vehicle-mounted system control system can determine whether the vehicle-mounted system has entered engineering mode. This system may include a cloud platform, the vehicle-mounted system, and a mobile terminal. The cloud platform may include an engineering mode cryptographic processing module and an engineering mode master key list, while the vehicle-mounted system may include an engineering mode cryptographic processing module and a security module.

[0073] In this embodiment, the aforementioned engineering mode cryptography module can be used to encrypt the vehicle model master key and the vehicle's VIN code obtained from the cloud platform to obtain the engineering mode cryptography K to be output by the cloud platform. The aforementioned engineering mode master key list can be used to store the vehicle model master key in the cloud platform. The aforementioned engineering mode cryptography module can be used to encrypt the vehicle model master key and the vehicle's VIN code obtained from the vehicle's infotainment system to obtain the engineering mode cryptography K' to be output by the vehicle's infotainment system. The aforementioned security module can be used to store the vehicle model master key in the vehicle's infotainment system. The aforementioned mobile terminal can be used to log in to the cloud platform and to obtain the engineering mode cryptography queried from the cloud platform. The aforementioned mobile terminal can also be used to input the obtained engineering mode cryptography queried from the cloud platform into the password input interface of the vehicle's infotainment system.

[0074] In this embodiment, the cloud platform can generate a corresponding master key for each vehicle model and store the generated master key in the engineering mode master key list.

[0075] Optionally, R&D and after-sales personnel can log in to the cloud platform via mobile terminals. Login authentication can be performed using employee identification (ID) accounts, passwords, etc. By entering the VIN code of the vehicle requiring debugging and troubleshooting, the engineering mode password for that vehicle can be obtained. After obtaining the engineering mode password, the password input interface for the vehicle's engineering mode is accessed. After successful password verification, the vehicle can enter engineering mode.

[0076] In this embodiment of the invention, when determining the vehicle's infotainment system mode, an input command applied to the system's interface can be used to obtain the system's initial password. Based on the obtained initial password and identification code, a second key stored in the system can be determined. Encrypting the determined second key and identification code yields the target password. Based on the obtained initial password and target password, it can be determined whether the system has entered engineering mode, thereby achieving the goal of avoiding significant threats to vehicle safety, solving the technical problem of low vehicle control security, and achieving the technical effect of improving vehicle control security.

[0077] Example 2

[0078] The technical solutions of the embodiments of the present invention will be illustrated below with reference to preferred embodiments.

[0079] In a vehicle, various problems can be troubleshooted and vehicle parameters adjusted by controlling the vehicle's infotainment system to enter engineering mode. However, if any person can easily control the system to enter engineering mode, it poses a significant threat to vehicle safety, resulting in a technical problem of low vehicle control safety.

[0080] To address the aforementioned technical problems, this invention proposes a method for determining entry into engineering mode. Based on the initial password input to the vehicle's infotainment system via its interface and the vehicle's identification code, a second key stored in the system can be determined. Encrypting this second key and the vehicle's identification code yields a target password. Based on the obtained target password and the initial password input to the system, it can be determined whether the system has entered engineering mode. This effectively avoids significant threats to vehicle security, solves the technical problem of low vehicle control security, and achieves the technical effect of improving vehicle control security.

[0081] In this embodiment, the vehicle-mounted infotainment system can determine whether the vehicle-mounted infotainment system has entered engineering mode. For example, Figure 2 This is a schematic diagram of a vehicle-mounted infotainment system according to an embodiment of the present invention, such as... Figure 2 As shown, the system may include: a cloud platform 201, a vehicle-mounted system 202, and a mobile terminal 203. The cloud platform 201 may include: an engineering mode cryptographic operation module 2011 and an engineering mode master key list 2012. The vehicle-mounted system 202 may include: an engineering mode cryptographic operation module 2021 and a security module 2022.

[0082] In this embodiment, the engineering mode password operation module 2011 can be used to encrypt the vehicle model master key and the vehicle's VIN code obtained from the cloud platform to obtain the engineering mode password K to be output by the cloud platform. The engineering mode master key list 2012 can be used to store the vehicle model master key in the cloud platform. The engineering mode password operation module 2021 can be used to encrypt the vehicle model master key and the vehicle's VIN code obtained from the vehicle's infotainment system to obtain the engineering mode password K' to be output by the vehicle's infotainment system. The security module 2022 can be used to store the vehicle model master key in the vehicle's infotainment system. The mobile terminal 203 can be used to log in to the cloud platform 201 and to obtain the engineering mode password queried by the cloud platform 201. The mobile terminal 203 can also be used to input the obtained engineering mode password queried by the cloud platform 201 into the password input interface of the vehicle's infotainment system.

[0083] In this embodiment, the cloud platform 201 can generate a corresponding master key for each vehicle model and store the generated master key in the engineering mode master key list 2012.

[0084] Optionally, R&D and after-sales personnel can log in to the cloud platform via mobile devices, authenticating their identity using employee ID accounts, passwords, etc. By entering the VIN code of the vehicle requiring debugging and troubleshooting, the engineering mode password for that vehicle can be obtained. After obtaining the engineering mode password, the system enters the password input interface for the vehicle's engineering mode. Upon successful password verification, the system can enter engineering mode.

[0085] It should be noted that the aforementioned engineering mode password can be a derived key generated by performing cryptographic operations on the master key and the vehicle's VIN code for that model. The engineering mode password calculation module does not store the engineering mode password output by the vehicle's infotainment system. Only when a verification requirement arises for the engineering mode password, the vehicle's infotainment system retrieves the master key and the vehicle's VIN code from the security module and inputs them into the engineering mode password calculation module for processing. The resulting engineering mode password can then be used to verify the input engineering mode password.

[0086] In this embodiment, the vehicle-mounted system control system can execute the vehicle-mounted system control method to determine whether the vehicle-mounted system has entered engineering mode. For example, Figure 3 This is a flowchart of a vehicle system mode control method according to an embodiment of the present invention, such as... Figure 3 As shown, the method may include the following steps:

[0087] Step S301: Log in to the cloud platform via mobile terminal.

[0088] After logging into the cloud platform via mobile terminal, proceed to step S302 to verify the user's identity.

[0089] If user authentication fails, the method execution ends. If user authentication succeeds, proceed to step S303 and enter the vehicle VIN code to be queried.

[0090] After entering the VIN code of the vehicle to be queried, proceed to step S304 to query the master key of the vehicle model.

[0091] After querying the master key for the vehicle model, proceed to step S305, where the engineering mode password K for the vehicle is calculated using the cloud-based cryptographic calculation module.

[0092] After calculating the engineering mode password K for the vehicle, proceed to step S306 and return the queried engineering mode password K.

[0093] After returning the queried engineering mode password K, proceed to step S307, click on the vehicle screen, and enter the password input interface corresponding to the vehicle engineering mode.

[0094] After clicking on the vehicle's infotainment screen and entering the password input interface corresponding to the vehicle's engineering mode, proceed to step S308 and enter the obtained engineering mode password K.
