[0051] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0052] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0053] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle pre-programming condition analysis device, etc. The following takes the vehicle pre-programming condition analysis device as an example to illustrate this embodiment and the following embodiments.

[0054] Based on this, the embodiment of the present application provides a vehicle pre-programming condition analysis method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle pre-programming condition analysis method of the present application.

[0055] In this embodiment, the vehicle pre-programming condition analysis method includes steps S10 to S40:

[0056] Step S10, obtaining vehicle message information;

[0057] It should be noted that the vehicle message information is used to transmit data between the vehicle's electronic control unit (ECU) and the diagnostic tool.

[0058] Step S20, determining message flag information according to vehicle message information;

[0059] It should be noted that the message flag information at least includes vehicle speed, gear position, parking position, charging status and high voltage status.

[0060] It should be understood that the flag bit in the vehicle diagnostic message is a bit used to indicate a specific state or attribute. In CAN (Controller Area Network) communication, a standard data frame contains multiple flag bits, each of which has a different meaning.

[0061] Understandably, these flags are extremely important to diagnostic tools and repair personnel, providing detailed information about the vehicle's status and potential problems. By analyzing these flags, the problem with the vehicle can be more accurately determined.

[0062] Further, obtaining vehicle history data;

[0063] Analyze the real-time vehicle data and the historical vehicle data, and dynamically adjust the type of message flag information based on the analysis results.

[0064] It should be noted that the collection of historical data of the vehicle may include previous diagnostic records, maintenance records, fault codes (DTC), etc.

[0065] In a specific implementation, statistical analysis, machine learning, or deep learning algorithms can be used to identify patterns or anomalies in the data, and then analyze vehicle behavior to identify patterns of normal operation and potential failures. Based on the analysis results, it is determined whether the type of message flag information needs to be adjusted.

[0066] For example, if a specific failure mode is discovered, it may be necessary to add a new flag bit to indicate this failure condition.

[0067] It should be noted that the type of pre-programmed conditional signal is not fixed. The purpose of analyzing the real-time vehicle data and the vehicle historical data and adjusting the pre-programmed conditional signal is to find the problem more accurately.

[0068] It should be understood that after determining the new message flag information, the vehicle's diagnostic system is updated in real time so that it can send a message containing the new flag.

[0069] Step S30, performing a pre-programmed condition check according to the message flag information and determining the check result;

[0070] In the specific implementation, the pre-programmed conditional check compares the flag bit to be read with the preset conditions to evaluate whether the vehicle meets these conditions. If a flag bit is out of the normal range, the corresponding message flag bit is set, and the comparison result is used to determine whether the check passes. If all preset conditions are met, the check result is "passed".

[0071] If any of the conditions are not met, the check result is "FAIL" and further diagnosis or repair is required.

[0072] Step S40: Perform vehicle message error analysis based on the inspection result.

[0073] In the specific implementation, the root cause of the problem is fed back in the form of a diagnostic message.

[0074] It should be noted that the inspection result is the updated vehicle message, and the possible scenarios are as follows:

[0075] Value(B) 0000 0011 0000 0101 0000 1001 0001 0001 0010 0001 Value (Hex) 0x03 0x05 0x09 0x11 0x21 Result interpretation Speed ​​is not satisfactory The gear is not satisfied Parking is not satisfactory Charging status is not satisfactory High pressure state is not satisfied

[0076] The above table only lists the scenarios where a single pre-programmed condition signal is not met. If multiple conditions are not met, they are judged according to the "&&" relationship.

[0077] It should be understood that the above table can be used to intuitively understand whether the corresponding message flag bit has passed the check, so as to directly locate the root cause of the failure to meet the pre-programmed conditions through the diagnostic message replied by the ECU.

[0078] Furthermore, after step S40, the method further includes:

[0079] The inspection results are displayed through the user interface, and the conclusions of the vehicle message error analysis are displayed to show the satisfaction of all pre-programmed conditions.

[0080] It should be noted that by displaying the inspection results through the user interface, the root cause of the failure to meet the pre-programmed conditions can be clearly and intuitively seen, so that the user or maintenance technician can quickly understand the status of the vehicle.

[0081] The present embodiment provides a vehicle pre-programming condition parsing method, which obtains vehicle message information; determines message flag information based on the vehicle message information; performs a pre-programming condition check based on the message flag information to determine the check result; performs a vehicle message error analysis based on the check result, directly analyzes and feeds back the root cause of the problem in the form of a message.

[0082] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S20, the vehicle pre-programming condition analysis method further includes steps S201-S202:

[0083] Step S201, determining a pre-programmed condition check data byte according to a vehicle message, wherein the pre-programmed condition check data byte includes 8 bits;

[0084] In a specific implementation, data of 1 byte size is defined in the vehicle message, and the result and reason of failure of the pre-programmed inspection are fed back according to the content.

[0085] It should be noted that in vehicle diagnostic communication, when the ECU (Electronic Control Unit) receives a diagnostic request message, it will generate a response message based on the content of the request and the current state of the vehicle. Usually, if the requested service or data cannot be executed or provided, the ECU will reply with a negative response (Negative Response), which contains a negative response code (NRC)

[0086] Therefore, in this strategy, even if the pre-programming check fails, the ECU is required to reply with an affirmative response instead of replying to NRC22 "The requested service or data is not supported". The diagnostic message is defined as: Response: 0x71 0x01 0x02 0x03 0xXX.

[0087] Among them, 0x71 is the starting byte of the response message, which is usually a fixed value used to identify that this is a response message.

[0088] 0x01 is the service identifier (SID), which indicates the request service corresponding to the response message.

[0089] 0x02 is the sub-function or parameter byte, the specific meaning depends on the definition of the service.

[0090] 0x03 is the data length code (DLC), which indicates the length of the subsequent data field.

[0091] 0xXX is the data field, its content depends on the requested service and the current state of the ECU. In this case, the ECU will send a positive response instead of NRC even if the pre-programmed check does not pass.

[0092] If 0xXX is 0x00, the pre-programming condition check passes; if it is not 0x00, the pre-programming condition check fails.

[0093] Using a single byte to represent multiple possible error conditions gives the ECU the flexibility to indicate which specific pre-programmed condition was not met, allowing diagnostic tools to quickly locate the problem.

[0094] Step S202, storing the result bit of the pre-programmed condition check and the message flag information through each bit of the pre-programmed condition check data byte, wherein the message flag information includes a vehicle speed flag, a gear flag, a parking position flag, a charging status flag and a high voltage status flag.

[0095] It should be noted that the pre-programmed condition signal includes at least vehicle speed, gear position, parking position, charging status and high voltage status.

[0096] In the specific implementation, 0xXX bytes are used to define each pre-programmed condition signal to occupy 1 bit, and they are arranged in sequence. The vehicle speed, gear position, parking position, charging status and high voltage status correspond to bit1 to bit5 respectively, namely bit1: vehicle speed; bit2: gear position; bit3: parking position; bit4: charging status; bit5: high voltage status.

[0097] It should be noted that bit 6 and bit 7 are reserved for subsequent extended pre-programming condition signals.

[0098] As shown in the following table:

[0099]

[0100] It should be understood that in actual applications, the ECU's diagnostic software needs to set these bits according to the actual state of the vehicle. For example, if the vehicle speed exceeds a preset threshold, then bit 1 will be set to 1; if the vehicle speed is below the threshold, bit 1 will be set to 0. The same method applies to other conditional signals.

[0101] This bit mapping method provides a compact way to represent multiple status information in a single byte, making diagnostic communication more efficient. However, it also requires the diagnostic tool to correctly interpret the meaning of these bits and ensure that all diagnostic participants follow the same bit definition standards.

[0102] This embodiment provides a vehicle pre-programming condition parsing method. By defining a byte (0xXX) to represent the result and cause of the pre-programming check, the ECU can provide clear and detailed feedback information to the diagnostic tool. Even if the pre-programming check fails, the ECU can reply with an affirmative response instead of an error code (such as NRC22), which simplifies the diagnostic process and improves the efficiency of communication. The ECU can flexibly perform pre-programming condition checks and clearly feedback the inspection results and causes through diagnostic response messages, while retaining the possibility of expansion.

[0103] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 3 , step S30, including steps S301 to S304:

[0104] Step S301, setting a signal analysis rule according to the message flag information;

[0105] It should be noted that the signal parsing rules define how to extract and interpret the status of each signal from the message.

[0106] In the specific implementation, when the vehicle speed (VehSpeed), gear position (AcGear), parking position (EPBSts), charging status (ChargeSts), and high voltage status (HvSts) all meet the corresponding conditions (pre-programmed check passed).

[0107] Pre-programmed condition check failed:

[0108] When any of the vehicle speed (VehSpeed), gear position (AcGear), parking position (EPBSts), charging status (ChargeSts), and high voltage status (HvSts) does not meet the corresponding conditions (pre-programmed check fails).

[0109] Step S302, performing a pre-programmed condition check on the message flag information according to the signal analysis rule to obtain a check result;

[0110] It should be noted that the inspection result is the vehicle diagnostic message after the vehicle message is updated by the pre-programmed condition inspection data bytes.

[0111] Furthermore, the step S302 includes:

[0112] Determine the vehicle speed, gear position, parking position, charging status and high voltage status corresponding to the message flag information according to the real-time data of the vehicle;

[0113] When the message flag information satisfies the corresponding pre-programmed conditions of the parsing rules, the bits corresponding to the pre-programmed condition check data bytes are set to 0;

[0114] If not, the bit corresponding to the pre-programmed condition check data byte is set to 1;

[0115] The vehicle message information is updated based on the processed pre-programmed condition check data bytes to obtain the check result.

[0116] It should be understood that the vehicle real-time data is acquired in a targeted manner based on the pre-programmed conditions in the ECU diagnosis, including at least the vehicle speed (VehSpeed), gear position (AcGear), parking position (EPBSts), charging status (ChargeSts), and high voltage status (HvSts).

[0117] It should be noted that 0xXX bytes are used to define each pre-programmed condition signal as one bit, and they are arranged in sequence corresponding to bit1 to bit5. The ECU application software checks the pre-programmed condition signals respectively. If the conditions are met, the corresponding position is set to 0, otherwise it is set to 1. Bit 0 is the result bit of the pre-programmed condition check, and is set based on the setting results of bit1 to bit5.

[0118] In a specific implementation, the transmission control system is checked to determine the current gear position. If the gear position is in a specific gear position, such as the P gear, the pre-programmed condition signal position corresponding to the gear position is set to 0.

[0119] Use the parking sensor or switch to detect whether the vehicle is in the parked state. If the vehicle is parked, the pre-programmed condition signal position of the parking position is set to 0.

[0120] Check the battery management system to determine whether the vehicle is in a charging state and whether the charging state meets the requirements, such as not charging. If the conditions are met, set the pre-programmed condition signal position of the charging state to 0.

[0121] Monitor the status of the high-voltage electrical system to ensure that it is within a safe range and meets specific conditions, such as the high-voltage system is shut down. If the high-voltage status meets the pre-programmed conditions, set the pre-programmed condition signal position of the high-voltage status to 0.

[0122] Furthermore, the step of updating the vehicle message information based on the processed pre-programmed condition check data bytes to obtain the check result further includes:

[0123] After all bytes corresponding to the message flag information of the pre-programmed condition check data byte are set, the result bit of the pre-programmed condition check data byte is set to obtain the target pre-programmed condition check data byte;

[0124] The vehicle message information is updated based on the target data byte structure to obtain the inspection result.

[0125] It should be noted that if Figure 4 As shown, Figure 4 The pre-programmed condition flow chart is parsed for the ECU application software. Based on the judgment of five pre-programmed condition signals, the output of bit0 is obtained.

[0126] Step S303, when all the message flag information meets the preset conditions, determining that the check result is passed for the pre-programmed condition check;

[0127] In a specific implementation, when bit1==1 and bit2=1 and bit3==1 and bit4==1 and bit5==1 are satisfied, bit0 is set to 0, and it is determined that the pre-programming check has passed.

[0128] Step S304: when the message flag information does not all meet the preset conditions, it is determined that the check result is that the pre-programmed condition check fails.

[0129] In a specific implementation, when bit1==1 or bit2=1 or bit3==1 or bit4==1 or bit5==1 is satisfied, bit0 is set to 1, and it is determined that the pre-programming check fails.

[0130] It should be noted that when the check passes or fails, log information is recorded to facilitate problem tracking and system monitoring. If the system does not respond within a certain period of time during the pre-programmed condition check, a timeout will be triggered; define error codes for different error conditions and provide more detailed error information. Provide user interface feedback or warning information when the pre-programmed condition check fails; give the system or user a chance to retry when the pre-programmed condition check fails; pre-programmed condition checks may depend on other system states or variables, ensure that these dependencies are also within the scope of the check; add security-related checks to pre-programmed condition checks, such as permission verification, data encryption, etc.; monitor system performance during the check to ensure that the check operation does not have a negative impact on system performance; allow the check rules to be adjusted through configuration files or parameters to adapt to different application scenarios.

[0131] This embodiment provides a vehicle pre-programming condition analysis method, which directly analyzes and feedbacks the root cause of non-satisfaction of pre-programming conditions through ECU application software, greatly simplifies the process of data collection and problem analysis, and improves the efficiency of real vehicle ECU flashing.

[0132] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vehicle pre-programming condition analysis method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
