[0040] It should be particularly noted that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0041] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0042] The embodiment provided in the present application, that is, an embodiment of a method for refreshing a vehicle controller, is applied to a diagnostic instrument on a vehicle controller.

[0043] Combine the following Figure 1 The embodiments of the present application are described in detail.

[0044] Step S101, obtaining a preset service instruction file for refreshing the controller.

[0045] Among them, each line in the preset service instruction file includes a refresh service information, and the arrangement order of each line matches the execution step order of the refresh service information. At least one line of refresh service information includes instruction information for calling a unit refresh script, and the unit refresh script is saved in the script data set.

[0046] A vehicle includes multiple controllers, and each controller performs different tasks in the vehicle. However, the flashing processes of each controller are not the same, so the flashing scripts of the diagnostic instrument for each controller are also different. In the prior art, it is necessary to write a dedicated flashing script for each controller, which is very time-consuming and labor-intensive. To this end, in an embodiment of the present application, a script data set is installed in the diagnostic instrument, and a plurality of unit refresh scripts are included in the script data set. Each unit refresh script can complete a minimum refresh function. The embodiment of the present application decomposes the original refresh scripts of each controller into a plurality of universal unit refresh scripts. Before refreshing the controller each time, according to the refresh characteristics of the controller, the call information of the plurality of unit refresh scripts related to the controller in the script data set is collected as refresh service information in the preset service instruction file, and the diagnostic instrument calls the corresponding unit refresh script through the refresh service information set in the preset service instruction file to refresh the controller.

[0047] For example, the preset service instruction file is a configuration file, which includes multiple lines, each line is configured with a refresh service information, when each line of refresh service information is read sequentially, that is, the steps of refreshing the service information are executed sequentially; the refresh service information is edited according to the prescribed format; when used, the refresh service information is decomposed according to the prescribed format to obtain the necessary execution information.

[0048] In some specific embodiments, each line in the preset service indication file includes a plurality of indication items, wherein the plurality of indication items include at least a service item, and the service item includes task information of a refresh service.

[0049] For example, the preset service indication file is a spreadsheet file, and the table in the spreadsheet file is used to save the contents of the indication items, wherein one column of the indication items is the service items, and the task information is saved in the table of the service items; the task information includes: long frame data information, short frame data information, "36" and "WT xxxx ms"; the long frame data information means transmitting the long frame data information to the controller; the short frame data information means transmitting the short frame data information to the controller; "36" represents refreshing the controller through the unit refresh script, and "WT 1000ms" means maintaining the session status with the controller during the idle time within 1000ms.

[0050] This specific embodiment can implement different refresh tasks for different controllers through the indication items of the service items and the flexible combination of the service items.

[0051] In some specific embodiments, the multiple indication items also include addressing mode information; the addressing mode information includes functional addressing information and physical addressing information.

[0052] The function addressing information indicates that all controllers in the vehicle are refreshed this time.

[0053] The physical addressing information indicates that a refresh is performed on a specific controller in the vehicle.

[0054] For example, a table of a column of indicator items in a spreadsheet file is used to record addressing mode information, where "F" represents functional addressing information; and "P" represents physical addressing information.

[0055] This specific embodiment enables the refresh work to flexibly adapt to various refresh requirements through the indication items of the addressing mode information.

[0056] In some specific embodiments, the multiple indication items also include a communication duration for transmitting a group of continuous frames, and the communication duration matches the task information.

[0057] Usually, after the diagnostic instrument shakes hands with the controller, the controller will feedback the communication duration of a group of continuous frames to the diagnostic instrument, and the diagnostic instrument will transmit a group of continuous frames according to the feedback communication duration. However, the communication duration fed back by some special processors is inaccurate, or the communication rate of the processor does not match the communication rate of the diagnostic instrument, resulting in loss of communication data. In order to ensure the security and reliability of data communication, this specific embodiment provides an indication of the communication duration.

[0058] In some specific embodiments, the plurality of indication items also include the unit refresh script.

[0059] For example, the service item in the i-th line in the preset service indication file is "36", the communication duration is 10ms, and the unit refresh script is "Script A" in the script data set. The refresh service information indicates that "Script A" in the script data set will be transmitted to the controller within 10ms.

[0060] Step S102, traverse each line in the preset service indication file in sequence, and obtain refresh service information of the corresponding line.

[0061] Step S103: Refresh the controller based on the refresh service information of each row.

[0062] In an embodiment of the present application, a script data set is installed in the diagnostic instrument, and the script data set includes multiple unit refresh scripts. Each unit refresh script can complete a minimum refresh function. Before refreshing the controller each time, according to the refresh characteristics of the controller, the call information of multiple unit refresh scripts related to the controller in the script data set is collected as refresh service information in a preset service instruction file. The arrangement order of the refresh service information in each line of the preset service instruction file is also the order of the refresh steps. The diagnostic instrument refreshes the controller in sequence by sequentially traversing the refresh service information in each line of the preset service instruction file. Through the flexible combination of refresh service information, different refresh tasks can be implemented for different controllers while the unit refresh script in the script data set remains unchanged. The flexibility, adaptability and convenience of the refresh are improved through the configuration of the preset service instruction file.

[0063] In some specific embodiments, the method further comprises the following steps:

[0064] Step S100, before sequentially traversing each line in the preset service instruction file, when it is detected that the controller is in a turned-off state, calling the power-on script corresponding to the controller in the script data set to enable the programmable power supply to power the controller.

[0065] This specific embodiment manages the program-controlled power supply before refreshing the controller to ensure that the refreshed controller can enter the power-on state, so that the controller can always communicate with the diagnostic instrument. No matter what state the vehicle is in, the controller can always be refreshed.

[0066] In some specific embodiments, the method further comprises the following steps:

[0067] During the refresh idle time, the session state with the controller is maintained based on preset heartbeat information.

[0068] For example, continuing the above example, the preset service instruction file is a spreadsheet file, and the record content of the spreadsheet file is:

[0069]

[0070] First, download the edited spreadsheet file to the diagnostic instrument;

[0071] Second, the power connection method of each controller in the vehicle is different. Before starting to traverse the preset service instruction file, if it is detected that the refreshed controller is in a closed state, the power connection script corresponding to the controller in the script data set is called to enable the program-controlled power supply to power the controller;

[0072] Third, read multiple indication items in the first row of the spreadsheet file, where the addressing mode information is "F", the service item is "Data1", and the communication duration is blank, indicating that the communication duration fed back by the controller is used by default to send "Data1" data to all controllers in the vehicle;

[0073] Fourth, read multiple indication items in the second row of the spreadsheet file, where the addressing mode information is "F", the service item is "Data2", and the communication duration is blank, indicating that the communication duration fed back by the controller is used by default to communicate and send "Data2" data to all controllers in the vehicle;

[0074] Fifth, read multiple indication items in the third row of the electronic spreadsheet file, among which only the service item "WT 1000ms" indicates that the session state with the controller is maintained through the preset heartbeat information "3E80" during the idle time within 1000ms;

[0075] Sixth, read multiple indication items in the fourth row of the spreadsheet file, where the addressing mode information is "P", the service item is "36", the communication duration is 10ms, and the unit refresh script is "script A", indicating that "script A" in the script data set is transmitted to the refreshed controller within 10ms to refresh the controller;

[0076] Seventh, read multiple indication items in the fifth row of the electronic spreadsheet file, where the addressing mode information is "P", the service item is "Data3", and the communication duration is 20ms, indicating that the "Data3" data is transmitted to the refreshed controller within 20ms;

[0077] ...until you reach the end of the spreadsheet file.
