The terms (such as those defined in a general use dictionary) will be interpreted to have the same meaning as the contextual meaning in the relevant technical field and will not be interpreted to have an idealized meaning or an overly formal meaning, unless clearly defined in various embodiments of the present application.
[0040] The following will, with reference to the accompanying drawings, elaborate in detail on some embodiments of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.
[0041] First, an embodiment of the present application provides a parameter configuration system 100. Please refer to Figure 1 , which is a structural block diagram of the parameter configuration system 100 provided by an embodiment of the present application. The parameter configuration system 100 includes a diagnostic device 110 and a server 120. The diagnostic device 110 and the server 120 can be connected to achieve data transmission and interaction.
[0042] In one embodiment, the diagnostic device 110 includes a communication module. The diagnostic device 110 can be pre-connected to the server 120 through this communication module to achieve wireless communication with the server 120. Among them, the communication module includes but is not limited to a Wi-Fi module, a 4G / 5G module, etc.
[0043] In an embodiment of the present application, the diagnostic device 110 is used to send a parameter configuration request for a target vehicle to the server 120. The server 120 is used to provide a first ECU parameter modification case corresponding to the first target information to the diagnostic device 110 when the request includes the first target information; the server 120 is also used to provide a second ECU parameter modification case corresponding to both the first target information and the second target information to the diagnostic device 110 when the request includes the first target information and the second target information. Further, the diagnostic device 110 configures the parameters of the target vehicle according to the received first ECU parameter modification case or the second ECU parameter modification case, realizing personalized configuration of the ECU parameters.
[0044] Next, for the sake of easy understanding, the following embodiments of the present application will take Figure 1 the parameter configuration system shown as an example, and in combination with Figure 1, elaborate on the parameter configuration method provided by the embodiments of the present application.
[0045] Figure 2 shows a flowchart of a parameter configuration method according to an embodiment of the present application. Exemplarily, this parameter configuration method is applied to the diagnostic device 110 and specifically includes the following steps:
[0046] S210. Send a parameter configuration request for the target vehicle to the server 120.
[0047] In one embodiment, before sending the parameter configuration request, the diagnostic device 110 pre - establishes a secure communication channel with the server 120 that provides ECU parameter modification cases, specifically including: establishing a connection with the server 120 through the communication module, and performing authentication and handshake with the server 120 based on the Hypertext Transfer Protocol Secure (HTTPS) to establish a secure communication channel with the server 120.
[0048] In one implementation, when the diagnostic device 110 communicates with the server 120 using the HTTPS method, first, the diagnostic device 110 sends an HTTPS request to the server 120 through the communication module, requesting to establish an SSL (Secure Sockets Layer) connection with the server 120. After receiving the request from the diagnostic device 110, the server 120 transmits the certificate information to the diagnostic device 110. The browser of the diagnostic device 110 and the server 120 start negotiating the security level of the SSL connection, that is, the level of information encryption. The diagnostic device 110 establishes a session key according to the agreed - upon security level, then encrypts the session key using the public key. The server 120 decrypts the session key using the private key, and encrypts the communication with the diagnostic device 110 using the session key.
[0049] Exemplarily, an ECU parameter modification case refers to an actual application case of adjusting and optimizing the internal parameters in an automotive electronic control unit. Through the modification of ECU parameters in this application, the addition and customization of specific functions are achieved.
[0050] In one embodiment, the diagnostic device 110 sends a parameter configuration request to query the ECU parameter modification case corresponding to the target vehicle. Among them, the mandatory items of this request include the first target information, and the non - mandatory items of this request include the second target information.
[0051] S220. When the request only includes the first target information, receive the first ECU parameter modification case corresponding to the first target information provided by the server 120.
[0052] In one embodiment, the first target information includes the target brand and model, and the ECU parameter modification case includes a model identifier. This application receives the first ECU parameter modification case corresponding to the first target information provided by the server 120, including: receiving the first ECU parameter modification case corresponding to the model identifier that is the same as the target brand and model queried by the server 120 in the ECU parameter modification case library, so as to perform parameter configuration on the target vehicle according to the first ECU parameter modification case.
[0053] It can be understood that when the parameter configuration request only includes the target brand model, the server 120 will query the first ECU parameter modification case related to the target brand model, and return the first ECU parameter modification case to the diagnostic device 110 for display.
[0054] S230, when the request includes the first target information and the second target information, receive the ECU parameter modification case jointly corresponding to the first target information and the second target information provided by the server 120.
[0055] In one embodiment, the second target information includes the target function, that is, the name of the personalized function that the user wants to configure. The ECU parameter modification case further includes a first function identifier. This application receives the second ECU parameter modification case jointly corresponding to the first target information and the second target information provided by the server 120, including: the server 120 queries in the ECU parameter modification case library for the second ECU parameter modification case corresponding to the vehicle model identifier that is the same as the target brand model and the first function identifier that is the same as the target function, so as to perform parameter configuration on the target vehicle according to the second ECU parameter modification case.
[0056] In one implementation manner, when the parameter configuration request includes the target function and the target brand model, the server 120 queries in the set of the first ECU parameter modification cases related to the target brand model for the second ECU parameter modification case corresponding to the target function, and returns the second ECU parameter modification case to the diagnostic device 110 for display.
[0057] Exemplarily, when the server 120 queries the ECU parameter modification case according to the first target information and the second target information, there is no strict execution order. It can be executed synchronously, or first judge whether there is the first target information, and then judge whether there is the second target information, etc., so as to determine the final ECU parameter modification case.
[0058] In one implementation manner, the brand of the target vehicle includes all vehicle brands on the market, and the vehicle models include sedans, sports cars, SUVs (sport utility vehicles), commercial vehicles, electric vehicles, etc., which are not limited here.
[0059] S240, perform parameter configuration on the target vehicle according to the first ECU parameter modification case or the second ECU parameter modification case.
[0060] In one embodiment, the ECU parameter modification case further includes function parameters, and the function parameters include different preset values. This application configures the parameters of the target vehicle according to the first ECU parameter modification case or the second ECU parameter modification case, including: setting the function parameters to the corresponding preset values according to the ECU parameter modification case, where different preset values correspond to different second function identifiers.
[0061] In one implementation, the target function can be to change the number of times the turn signal flashes. The factory setting of the left and right turn signals of the vehicle is to flash 3 times when toggled once. The personalized configuration of the ECU parameters can adjust the ECU parameters to set the number of times the turn signal flashes. For example, the first function identifier of the ECU parameter modification case is the number of times the turn signal flashes, and the ECU parameter involved in the adjustment is the turn signal flashing frequency parameter. When the turn signal flashing frequency parameter is set to Param_1, the function parameter for changing the number of times the turn signal flashes can be set to Param_1. By adjusting the corresponding preset value Param_1_Value of Param_1, the number of times the turn signal flashes can be changed. Param_1_Value can be modified within a certain range, such as 1, 3, 5, 7, 10, etc., which is not limited here. Among them, different preset values correspond to different numbers of times the turn signal flashes, that is, the second function identifier.
[0062] In another implementation, the target function can also be to change the host startup screen. Some chassis of Mercedes-Benz cars allow changing the host startup screen of the central control screen. For the Mercedes-Benz cars with chassis number 205 and chassis number 213, the host startup screen can be Mercedes-Benz, AMG (Aufrecht, Melcher, and Großaspach, Mercedes-AMG), Maybach, etc. For example, the vehicle model identifier of the ECU parameter modification case is a Mercedes-Benz brand car, and the first function identifier is to change the host startup screen. The ECU parameter involved in changing the host startup screen is the startup screen setting parameter. When the startup screen setting parameter is set to Param_2, the function parameter for changing the host startup screen is Param_2. By adjusting the corresponding preset value Param_2_Value of Param_2, different host startup screens are displayed. Param_2_Value can be Type_1, Type_2, Type_3. Among them, the second function identifier corresponding to Type_1 is that the startup screen is Mercedes-Benz, the second function identifier corresponding to Type_2 is that the startup screen is AMG, and the second function identifier corresponding to Type_3 is that the startup screen is Maybach.
[0063] In another embodiment, the server 120 includes an ECU parameter modification case library for storing ECU parameter modification cases, which are classified according to the vehicle make and model, function name, and chassis number. The types of ECU parameter modification cases include: ECU parameter modification cases for implementing different functions in the same vehicle make and model; ECU parameter modification cases for implementing the same function in different vehicle makes and models. For example, Mercedes-Benz vehicles, Maybach vehicles, Toyota brand vehicles, and Audi brand vehicles can all modify the number of times the turn signal flashes. When modifying the number of times the turn signal flashes for vehicles of different makes and models, the corresponding function parameters of the vehicle make and model need to be modified. Therefore, different ECU parameter modification cases correspond to the same function in different vehicle makes and models. And ECU parameter modification cases for implementing the same function with different chassis in the same vehicle make. Since different chassis involve different ECUs to be modified, the ECU parameters involved are also different. For example, when the vehicle is configured to disable the start-stop function, there are different ECU parameter modification cases corresponding to Mercedes-Benz chassis 205, Mercedes-Benz chassis 222, and Mercedes-Benz chassis 213.
[0064] In one embodiment, the parameter configuration method further includes: uploading ECU parameter modification data to the server 120 so that the server 120 obtains at least one ECU parameter modification case based on the ECU parameter modification data, and adding the ECU parameter modification case to the ECU parameter modification case library.
[0065] Among them, the form of the ECU parameter modification data can be text, video, voice, etc., which is not limited here. The source of the ECU parameter modification data can be a tutorial case of an internal person of a third-party diagnostic equipment company, a modification case posted by a large number of auto repair technicians on short video platforms (such as Douyin, Xiaohongshu, and TikTok, etc.), a modification case posted on a professional auto repair forum, or a teaching case of a third-party training institution for training auto repair technicians.
[0066] In one embodiment, the present application splits the ECU parameter modification data according to the vehicle make and model, function, and chassis to obtain multiple different ECU parameter modification cases. For example, if the ECU parameter modification data includes ECU parameter modification cases with different vehicle makes and models but the same function name, the ECU parameter modification data is split and classified according to the vehicle make and model to obtain ECU parameter modification cases for implementing the same function in different vehicle makes and models.
[0067] In one embodiment, if the ECU parameter modification data includes ECU parameter modification cases of the same vehicle brand and model, the same function, and different chassis, the ECU parameter modification data is split according to the chassis. For example, if the ECU parameter modification data includes a video for modifying and disabling the start-stop function for a Mercedes-Benz chassis 205, a video for modifying and disabling the start-stop function for a Mercedes-Benz chassis 222, and a video for modifying and disabling the start-stop function for a Mercedes-Benz chassis 213, the ECU parameter modification data is split according to the chassis to obtain ECU parameter modification cases for the same vehicle brand and model with different chassis to achieve the same function.

[0072] In one embodiment, the parameter configuration method further includes: establishing a secure communication channel with the diagnostic device 110 in advance; obtaining at least one ECU parameter modification case according to the ECU parameter modification data, and adding the ECU parameter modification case to the ECU parameter modification case library.
[0073] The present application further provides a vehicle diagnostic device, which can be a vehicle diagnostic device such as an intelligent vehicle diagnostic device, a remote vehicle diagnostic device, and a remote video vehicle diagnostic device, etc., and is not limited here.
