[0041] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0042] Figure 1is a flowchart of a backup battery adaptation method provided in an embodiment of the present application, such as Figure 1 As shown, the method may include:

[0043] Step 101, receiving battery configuration parameter information of a replaced backup battery sent by an external configuration host computer when it is detected that the target vehicle is in a preset gear position and the target vehicle is in a powered-on state;

[0044] It should be noted that in the embodiment of the present application, the cockpit software is developed at one time to adapt the adjustable parameter information of the backup battery. The software integrates a default charging limit, life percentage, temperature protection parameters and other information of the backup battery. Therefore, after replacing the backup battery, it can be quickly adapted by diagnosing the upper computer and writing new parameters. For example, the writing time can be achieved within 1 minute.

[0045] Therefore, first, it is necessary to ensure that the current state of the target vehicle meets the adaptation conditions, specifically, the target vehicle is in a preset gear position and the target vehicle is in a powered-on state, wherein the preset gear position can be set to P gear.

[0046] After the above conditions are met, the battery configuration parameter information of the replaced backup battery sent by the external configuration host computer can be received.

[0047] For details, please refer to Figure 2 ,The external configuration host computer can write the battery configuration parameter information of the ,replaced backup battery into the memory of the main chip through diagnostic ,communication④.

[0048] Specifically, the battery configuration parameter information includes battery charging parameters, battery life detection parameters and battery temperature protection parameters, that is, battery charging limit, life detection, and temperature protection configuration information.

[0049] Step 102, obtaining a diagnostic identifier variable corresponding to the preset battery configuration parameter information;

[0050] It should be noted that for the main chip, first of all, it can receive the data of the entire vehicle and package the data for uploading, and it can integrate the battery configuration parameter information of the backup battery. At the software level, these battery configuration parameter information is based on different backup batteries and needs to be integrated into adjustable parameter information through software.

[0051] In one embodiment, obtaining the diagnostic identifier variable corresponding to the preset battery configuration parameter information includes:

[0052] The data length, data unit, and data type in the diagnostic identifier variable corresponding to the preset battery configuration parameter information are obtained, and the write security level corresponding to the battery configuration parameter information is set.

[0053] For example, the main chip pre-sets the diagnostic identifier variable to realize software integration, wherein the corresponding diagnostic identifier variable can be set according to the battery configuration parameter information, and the diagnostic identifier DID is set for the backup battery charging limit, life detection, and temperature protection. Among them, DID is a data identifier, which is used for data identification.

[0054] For example, the battery charging limit DID may be A001&&A002, the data range is [X, Y], the data type is Unsigned, the conversion Phy==XX*0.001, the unit is volt (V); the X value range is 0 to 10000, and the Y value range is 0 to 10000.

[0055] The X value is written via the diagnostic identifier A001 DID, and the Y value is written via the diagnostic identifier A002 DID.

[0056] In addition, the life detection DID can be A003, the data range is [0,100], the data type is HEX, and the conversion Phy==XX%.

[0057] The temperature DID can be A004, the data range is [0,120], the data type is HEX, the conversion Phy==XX, and the unit is Celsius (℃).

[0058] Therefore, the main chip integrates the above DID data content into software as a variable parameter, receives external configuration host computer data, and saves it, thereby realizing that when the backup battery is replaced, external data needs to be written and saved through the diagnostic protocol, wherein the diagnostic protocol is a process based on DID writing data, wherein the external data refers to the battery parameters of the new backup battery, specifically, the charging upper and lower limits of the new backup battery (A001 and A002, for example [4.650V, 5.800V]); life detection percentage (A003, for example 50%, after reaching 50% of the remaining life, an alarm record is made and transmitted to the SOC chip through the universal asynchronous receiver and transmitter ⑦ (UART)); temperature protection limit (A004, for example, 60°C is written, when the alarm temperature is reached, an alarm record is made and transmitted to the SOC chip through the universal asynchronous receiver and transmitter ⑦).

[0059] Step 103: Write the battery configuration parameter information into a memory via a diagnostic identifier variable.

[0060] In one embodiment, writing the battery configuration parameter information into a memory via a diagnostic identifier variable comprises:

[0061] The battery configuration parameter information is written into the memory according to a preset diagnostic protocol via a diagnostic identifier variable.

[0062] Specifically, please refer to Table 1, which is an exemplary diagnostic protocol table.

[0063] Table 1 An exemplary diagnostic protocol table

[0064]

[0065]

[0066] For the new backup battery parameters involved in steps 7, 9, 11, and 13, after-sales technicians can manually query and then input them. After the diagnostic host computer obtains the data, it automatically writes steps 1 to 16 through diagnostic communication ④, without manual operation again. In addition, the diagnostic host computer will prompt whether the writing process is successful or failed.

[0067] Therefore, in the embodiment of the present application, a universal diagnostic protocol is used to ensure compatibility, which facilitates technicians to use standard tools to update parameters. At the same time, a verification mechanism is included to ensure the correctness of the parameters, and security measures are considered to prevent unauthorized access.

[0068] In one embodiment, the battery configuration parameter information includes battery charging parameters, battery life detection parameters, and battery temperature protection parameters, and writing the battery configuration parameter information into the memory according to a preset diagnostic protocol through a diagnostic identifier variable includes:

[0069] In the case where it is detected that the main chip enters the extended talkback mode, determining a target write security level;

[0070] writing the battery charging parameters into the memory via the diagnostic identifier variable in the event that the target write security level is detected to be in a positive response state;

[0071] In case that the battery charging parameter is detected to be in a positive response state, the battery life detection parameter is written into the memory through the diagnostic identifier variable;

[0072] When it is detected that the battery life detection parameter is in a positive response state, the battery temperature protection parameter is written into the memory through the diagnosis identifier variable.

[0073] It should be noted that in the embodiments of the present application, reference is made to Figure 4 ,A positive response means that the input battery configuration parameter ,information meets the variable specifications pre-set in the diagnostic identifier ,variable., For example, the main chip software sets the DID variable, the length, unit, data type and ,other of the DID.

[0074] In one embodiment, after the step of writing the battery configuration parameter information into a memory via a diagnostic identifier variable, the method comprises:

[0075] When it is detected that any of the battery configuration parameter information is repeatedly written into the diagnostic identifier variable for a preset number of times and is in a write failure state, a failure prompt is sent to the external configuration host computer.

[0076] During the writing process, if a certain item fails to be written, it can be written repeatedly for 3 times. After 3 write failures, the external diagnostic host computer needs to prompt. Generally, it can be written successfully in one time. Common write failures are as follows: the gear is not in P gear; the vehicle is not powered on; and negative diagnostic response, for example, the written value exceeds the range, the length is incorrect, etc.

[0077] In another embodiment, the main chip includes a memory, the main chip is communicatively connected to a power management module, and after the step of writing the battery configuration parameter information into the memory through the diagnostic identifier variable, the method includes:

[0078] The battery configuration parameter information is written into the memory through the diagnostic identifier variable, so that the power management module monitors the temperature of the backup battery by querying the battery temperature protection parameter in the diagnostic identifier variable stored in the memory, and sends an alarm message to the main chip when it is detected that the temperature of the backup battery reaches the battery temperature protection parameter;

[0079] The alarm information is received, and the alarm information is sent to a cockpit system chip, so that the cockpit system chip issues an alarm prompt.

[0080] It should be noted that the main chip receives the power status information provided by the serial port ⑤ power management module, uploads data in abnormal situations and promptly informs the saved backup battery configuration information "X", "Y", "N", "Z" values ​​through the serial port ⑤. Therefore, when the target vehicle is in the charging process, the power management module can query the temperature limit configuration information stored in the memory to monitor the temperature in real time. When the temperature limit is reached, the alarm information is transmitted to the main chip through the serial port ⑤ communication. Each time the power is turned on, the backup battery life test is required to reach the relevant alarm, and the alarm information is transmitted to the main chip through the serial port ⑤ communication.

[0081] After receiving data from the main chip, the SOC chip uploads the data and feeds back the upload status command to the MCU. When receiving the backup battery temperature is too high or the life is expired, it provides relevant alarm prompts.

[0082] For example, the life detection percentage is set to 50%. When the remaining life reaches 50%, an alarm record is made and transmitted to the cockpit system chip (i.e., SOC chip) through the universal asynchronous receiver and transmitter ⑦; the temperature protection limit is written as 60°C. When the alarm temperature is reached, an alarm record is made and transmitted to the SOC chip through the universal asynchronous receiver and transmitter ⑦.

[0083] In the embodiment of the present application, the main chip receives the battery configuration parameter information of the replaced backup battery sent by the external configuration host computer when detecting that the target vehicle is in a preset gear and the target vehicle is in a powered-on state; obtains the diagnostic identifier variable corresponding to the preset battery configuration parameter information; and writes the battery configuration parameter information into the memory through the diagnostic identifier variable. That is, in the embodiment of the present application, by developing the battery configuration parameter information that adapts to multiple backup batteries at one time, it is possible to quickly write new parameters through the external diagnostic host computer after replacing the backup battery to achieve rapid adaptation, which can reduce the complexity and cost of software updates and enable the vehicle to adapt to different battery configurations of backup batteries.

[0084] Corresponding to the method provided in the above-mentioned backup battery adaptation method embodiment of the present application, see Figure 2 , the present application also provides a system schematic diagram of a backup battery adaptation system. In this embodiment, the backup battery adaptation system includes an external configuration host computer and an intelligent cockpit controller; the intelligent cockpit controller includes a cockpit system chip and a microcontroller, and the microcontroller includes a main chip;

[0085] The main chip is used to receive the battery configuration parameter information of the replaced backup battery sent by the external configuration host computer when it is detected that the target vehicle is in a preset gear position and the target vehicle is in a powered-on state; obtain the diagnostic identifier variable corresponding to the preset battery configuration parameter information; and write the battery configuration parameter information into the memory through the diagnostic identifier variable.

[0086] It should be noted that in the embodiment of the present application, the external configuration host computer is used to write the backup battery charging limit, life detection, and temperature protection configuration information into the memory of the main chip through diagnostic communication ④, and there are relevant prompts.

[0087] In one embodiment, the backup battery adaptation system further includes a backup battery, a vehicle battery, and a cloud database;

[0088] The vehicle battery is used to power the cockpit controller, and to power the backup battery through the power management module;

[0089] The backup battery is used to supply power to the cockpit controller when it is detected that the vehicle battery is in a disconnected state;

[0090] The cloud database is used to store battery configuration parameter information corresponding to different types of backup batteries.

[0091] It should be noted that in the embodiment of the present application, under normal circumstances, the vehicle battery provides power to the entire cabin controller through hard wire ①, and provides charging power to the backup battery through the hard wire ② of the power management module.

[0092] After the vehicle battery is abnormally disconnected, the backup battery provides the necessary power for the cockpit controller to upload abnormal data, ensuring the normal upload of national standard data. In the embodiment of the present application, the backup battery types can be various, and the charging limit, life detection, and temperature protection value parameters of each battery are different.

[0093] The cloud database is used to store various parameter values ​​of different types of backup batteries.

[0094] In one embodiment, the main chip includes a memory, and the microcontroller also includes a power management module.

[0095] It should be noted that in the embodiments of the present application, reference is made to the foregoing discussion and no further details will be given here.

[0096] In summary, the embodiment of the present application provides a backup battery adaptation system, which receives the battery configuration parameter information of the replaced backup battery sent by the external configuration host computer when it is detected that the target vehicle is in a preset gear and the target vehicle is in a powered-on state; obtains the diagnostic identifier variable corresponding to the preset battery configuration parameter information; and writes the battery configuration parameter information into the memory through the diagnostic identifier variable.
