[0002] In the traditional vehicle safety / performance testing method (for example: vehicle network status, maintenance cycle, power, oil level, tire pressure, in-car air quality and air humidity, etc.), users need to go to the auto repair shop regularly to check the vehicle's related status in various aspects. However, in this way, users cannot know the vehicle's safety / performance status in real time, nor can they obtain specific relevant data. In other words, users cannot know at any time whether there is a problem with the vehicle's safety / performance and what aspects of the problem are there.

[0003] In this way, if the safety / performance of the vehicle suddenly has problems and the user cannot know it in time, it may cause damage to the vehicle and may also bring safety risks to the user. Therefore, existing vehicles are equipped with relevant monitoring systems to provide users with real-time feedback on vehicle safety-related data and issue corresponding warnings when the vehicle has safety problems.

[0038] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0039] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0040] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0041] In the related art, the traditional vehicle safety / performance detection method cannot enable the user to be informed of the vehicle's safety / performance problems at any time. Therefore, most existing vehicles are equipped with relevant monitoring systems to provide users with real-time feedback on vehicle safety-related data and issue corresponding warnings when the vehicle has safety problems. However, the methods for vehicle safety warning in the existing art need further improvement.

[0042] The present application provides a vehicle safety warning method, electronic equipment and a vehicle safety warning system, which can improve the effectiveness of vehicle safety warnings and improve user experience.

[0043] Figure 1 is a schematic diagram of a vehicle safety warning system provided by this application, Figure 2 It is a schematic diagram of an example terminal provided in this application.

[0044] In an exemplary embodiment, Figure 1 As shown, the vehicle safety warning method provided in this application can be applied to a vehicle safety warning system 100. The vehicle safety warning system 100 includes a terminal 110 and a server 120. Figure 2 As shown, the terminal 110 can be a vehicle-mounted terminal in a vehicle, and various applications (for example: application 1, application 2, application 3) can be configured in the vehicle-mounted terminal to realize corresponding functions and interaction with the user; the server 120 is a computer that establishes a communication connection with the terminal 110, and can be a physical server or a cloud server.

[0045] The terminal 110 can obtain various status parameters related to the safety / performance of the vehicle through the Controller Area Network (CAN) in the vehicle. The status parameters may include: parameters related to the performance of the terminal 110 (e.g., memory usage, CPU utilization, disk transfer rate, network throughput, etc.), vehicle maintenance status, remaining battery power or fuel level of the vehicle, tire pressure of the vehicle, air quality and humidity inside the vehicle, etc.

[0046] The terminal 110 can generate and output the vehicle's safety warning information (referred to as: first warning information) based on the warning strategy and the above-mentioned status parameters. The server 120 can further judge the validity of the first warning information (i.e., judge whether the vehicle does have safety / performance problems), and when the first warning information is invalid, update the warning strategy and send the updated warning strategy to the terminal 110, so that the terminal 110 can generate and output valid warning information.

[0047] Optionally, an application program (APP) can be configured in the terminal 110, so that the above-mentioned functions such as obtaining status parameters, interactive communication with the server 120 and outputting warning information can be implemented through the application, and interaction with the user can be realized through the visual interface of the application.

[0048] The specific implementation method of the vehicle safety warning information provided by this application is described below.

[0049] In an exemplary embodiment, the terminal 110 may be pre-configured with early warning strategies for different status parameters.

[0050] Among them, the early warning strategy may include: a mapping relationship between state parameters and warning levels, that is, the state parameters have corresponding warning levels at different numerical values; more specifically, the early warning strategy may include: a mapping relationship between state parameters, state scores, state levels and warning levels, that is, the state parameters have corresponding state scores at different numerical values, different state scores have corresponding state levels, and different state levels have corresponding warning levels; and the early warning strategy may also include: a mapping relationship between preset warning levels, warning levels, warning information and prompt intensity, that is, after the warning level reaches the preset warning level, the corresponding warning information is output, and different warning information has different prompt intensities.

[0051] Exemplarily, the warning level can be divided into three levels: high, medium, and low (or divided into level one, level two, level three, or other classification methods, which are not limited in this embodiment);

[0052] Furthermore, the preset warning level can be set to be medium (i.e., when the warning level is high or medium, the warning information is output), the warning information when the warning level is level one is a voice prompt, and the prompt information is displayed in the terminal 110 (high prompt intensity), etc.; the warning information when the warning level is level two is a prompt information displayed in the terminal 110, and a prompt information is sent to the user's mobile phone, etc. (medium / low prompt intensity), etc.;

[0053] And, the status level corresponding to the warning level can be set as: good (corresponding to low warning level), poor (corresponding to medium warning level), and urgent processing (corresponding to high warning level);

[0054] Furthermore, the status level corresponding to the status score may be set as follows: 100 to 70 points correspond to a good status, 69 to 40 points correspond to a poor status, and 39 to 0 points correspond to a status that requires urgent processing.

[0055] The mapping relationship between the status parameter and the status score / status level can be set according to the specific status parameter, for example:

[0056] For the memory usage of terminal 110 (100%~0%), the mapping relationship between it and the status score / status level can be set as: when the memory usage is in the range of 100%~70%, the corresponding status score is 0~39 points (urgent processing status); when the memory usage is in the range of 69%~40%, the corresponding status score is 40~69 points (poor status); when the memory usage is in the range of 39%~0%, the corresponding status score is 70~100 points (good status).

[0057] For the vehicle maintenance status, the mapping relationship between it and the status score (the status score can be calculated based on the number of days from the last maintenance) / status level can be set as follows: if the time from the last maintenance of the vehicle is less than or equal to 2 months, the corresponding status score is 100-80 points (good status); if the time from the last maintenance of the vehicle is 3-6 months, the corresponding status score is 79-40 points (poor status); if the time from the last maintenance of the vehicle is greater than or equal to 7 months, the corresponding status score is 39-0 points (urgent treatment status).

[0058] For the air humidity inside the vehicle, the mapping relationship between it and the status score (the status score can be set according to different temperatures and seasons to correspond to different air humidities) / status level can be set as follows: when the air humidity is in the range of 40% to 60%, the corresponding status score is 70 to 100 points (good status); when the air humidity is in the range of 20% to 39% and 61% to 80%, the corresponding status score is 40 to 69 points (poor status); when the air humidity is in the range of 0% to 19% and 81% to 100%, the corresponding status score is 0 to 39 points (urgent status).

[0059] It should be noted that the relevant contents set in the above-mentioned early warning strategies are all examples, and the early warning strategies can be flexibly configured according to actual conditions, which is not limited in this embodiment.

[0060] In an exemplary embodiment, after obtaining the current status parameters of the vehicle (which can be one or more), the terminal 110 can determine the warning level corresponding to each status parameter based on the warning strategy to determine whether there are safety / performance issues in the current status of the vehicle, and whether it is necessary to generate and output corresponding warning information.

[0061] For example, when the warning level reaches or exceeds the preset warning level, it is determined that there are safety / performance issues in the current state of the vehicle, and warning information with a prompt intensity corresponding to the warning level is output; when the warning level is lower than the preset warning level, it is determined that there are no safety / performance issues in the current state of the vehicle, and no warning information may be output.

[0062] Optionally, while outputting the warning information, the terminal 110 may also output a solution for dealing with the current safety / performance problem of the vehicle, so as to help the user effectively solve the current safety / performance problem of the vehicle.

[0063] Optionally, the terminal 110 may also display the status score or status level corresponding to each current status parameter of the vehicle in the interface, so that the user can view the status of the status parameter that he wants to know in real time.

[0064] refer to Figure 3a and Figure 3b The figure shows a schematic diagram of a first warning message output by a terminal.

[0065] Exemplarily, assuming that the terminal 110 obtains that the current memory usage of the vehicle is 80%, the terminal 110 can determine that the current memory usage of the vehicle is within the range of 100% to 70% according to the above-mentioned warning strategy (still taking the content of the warning strategy listed above as an example), and the corresponding status score is 20 points, which is in an urgent processing state, and the corresponding warning level is a high warning level (higher than the preset warning level). Then the terminal 110 can output a first warning message with a high prompt intensity, for example, it can output a voice prompt (for example, "Your memory usage is too high, please deal with it in time"), and output a display prompt message on the display interface, etc., to inform the user that the current memory usage of the terminal 110 is very high, and it is recommended to deal with it immediately. Optionally, the terminal 110 can also provide relevant processing solutions, such as: ending certain processes in the terminal 110, closing certain unnecessary services, and so on.

[0066] Assuming that the terminal 110 obtains the current vehicle maintenance status of the vehicle as: 3 months have passed since the last maintenance, the terminal 110 can determine that the status score corresponding to the current vehicle maintenance status of the vehicle is in the range of 40 to 69 points according to the above-mentioned warning strategy, which is in a poor state, and the corresponding warning level is a medium warning level (reaching the preset warning level). Then the terminal 110 can output a first warning message with a medium prompt intensity. For example, the prompt message can be displayed in the display interface, or a prompt message can be sent to the user's mobile phone, etc., to inform the user that the vehicle is currently a long time away from the last maintenance, and it is recommended to perform maintenance as soon as possible, etc. Optionally, the terminal 110 can also provide relevant processing solutions, such as: finding a nearby auto repair shop for the user, establishing a vehicle maintenance schedule and reminder for the user, etc.

[0067] Figure 4 This is an interactive diagram of an example of a vehicle safety early warning method provided by this application.

[0068] S40, when a safety problem of the vehicle is detected according to the warning strategy based on the current state parameters of the vehicle, a first warning message is output.

[0069] Exemplarily, if the terminal 110 analyzes the acquired current state parameters of the vehicle according to the above-mentioned warning strategy and determines that the vehicle currently has safety / performance problems, it generates and outputs the first warning information.

[0070] S42, sending the current status parameters of the vehicle and the first warning information to the server.

[0071] It is understandable that due to sensor errors or network delays, etc., the status parameters obtained by the terminal 110 may be inaccurate, or the warning strategy in the terminal 110 may not be in line with the actual condition of the vehicle, resulting in the first warning information output by the terminal 110 being invalid warning information; that is, the terminal 110 determines that the vehicle has safety / performance problems, but in fact the vehicle does not have any safety / performance problems, then the first warning information output by the terminal 110 is invalid warning information.

[0072] For example, Figure 3a As shown, assuming that the terminal 110 obtains that the vehicle's memory usage at a certain moment is 80%, and outputs a first warning message with a medium prompt intensity according to the warning strategy, but in fact the vehicle's memory usage is 30%, then according to the above warning strategy, it can be determined that there is no problem with the current memory usage, and the first warning message output by the terminal 110 is an invalid warning message.

[0073] For example, Figure 3b As shown, assuming that the terminal 110 outputs a first warning message with medium prompt intensity according to the warning strategy when three months have passed since the last maintenance cycle of the vehicle; but combined with the recent frequency of use of the vehicle, the frequency of use of the vehicle is very low (for example, it has only been used once in these three months), and therefore the vehicle does not need maintenance at present. It can be determined that there is actually no problem with the current maintenance status of the vehicle, and the first warning message output by the terminal 110 is an invalid warning message.

[0074] Therefore, after outputting the first warning information, the terminal 110 may obtain the current state parameters of the vehicle again, and send the above-reobtained state parameters and the first warning information to the server 120 .

[0075] S44, determining that the vehicle currently has no safety issues based on the current state parameters of the vehicle and the historical state parameters of the vehicle; and determining the first warning information as invalid warning information.

[0076] Exemplarily, the server 120 may determine whether the vehicle currently has a safety / performance problem based on the above state parameters and the above warning strategy. If the server 120 determines that the vehicle currently has no safety / performance problem based on the current state parameters and the warning strategy, the first warning information is determined to be invalid warning information.

[0077] Specifically, the server 120 can determine the warning level corresponding to each state parameter according to the warning strategy to determine whether there is a safety / performance problem in the current state of the vehicle. For example, when the warning level reaches or exceeds the preset warning level, it is determined that there is a safety / performance problem in the current state of the vehicle. The specific judgment method can refer to the relevant description of the terminal 110 determining whether there is a safety / performance problem in the current state of the vehicle in the above embodiment, which will not be repeated here.

[0078] For example, Figure 3a As shown, the memory usage obtained by the terminal 110 is 80%. Assuming that the actual memory usage obtained by the server 120 is 30%, it means that the information obtained by the terminal 110 is not accurate. Therefore, the server 120 can determine that the current memory usage of the vehicle is in a good state (the vehicle currently has no safety / performance problems) according to the warning strategy, and determine that the first warning information output by the terminal 110 is invalid warning information.

[0079] Exemplarily, the server 120 may also store historical status parameters of the vehicle. Compared with the current status parameters of the vehicle, the historical status parameters may include the status parameters previously acquired by the server 120; the historical status parameters may also include other parameters, such as the frequency of use of the vehicle, the current environment, climate, temperature, etc.

[0080] Thus, the server 120 can also determine whether the vehicle currently has a safety / performance problem based on the current state parameters, historical state parameters, and early warning strategies obtained. If the server 120 determines that the vehicle currently has no safety / performance problem based on the current state parameters, historical state parameters, and early warning strategies, the first early warning information is determined to be invalid early warning information.

[0081] Specifically, the server 120 can combine the historical state parameters and the current state parameters to determine whether the warning strategy is reasonable, that is, whether the warning strategy is consistent with the actual situation of the vehicle. If the warning strategy is not consistent with the actual situation of the vehicle, it can be determined that the vehicle currently has no safety / performance problems and the first warning information is invalid warning information.

[0082] For example, Figure 3bAs shown, the terminal 110 determines that the vehicle currently needs maintenance according to the early warning strategy. Assuming that the server 120 determines that the user's actual use frequency of the vehicle is not high according to the historical status parameters of the vehicle, it means that the vehicle does not need to be maintained according to the current maintenance cycle, that is, the current early warning strategy does not meet the actual situation of the vehicle well. Therefore, the server 120 can determine that the vehicle currently does not need maintenance (the vehicle currently has no safety / performance problems), and determine that the first early warning information output by the terminal 110 is invalid early warning information.

[0083] S46, updating the early warning strategy according to the current state parameters of the vehicle and the historical state parameters of the vehicle.

[0084] Exemplarily, when the warning strategy does not conform to the actual state of the vehicle, the server 120 may update the current warning strategy based on data such as current state parameters and historical state parameters. Specifically, when updating the warning strategy, the server 120 may determine the critical state parameters corresponding to when the vehicle has a safety problem based on data such as the current state parameters and historical state parameters of the vehicle, and update the warning strategy based on the critical state parameters.

[0085] For example, in the vehicle maintenance example described in S44, the server 120 can determine the next maintenance time of the vehicle based on the vehicle usage frequency, the wear and tear of each component, etc. in the historical status parameters, that is, determine the critical status parameter for early warning of the maintenance status, for example, setting the critical status parameter of vehicle maintenance to 12 months. In this way, if the vehicle has not been maintained again after 12 months from the last maintenance, the early warning information can be output, so that the early warning strategy can better meet the actual status of the vehicle.

[0086] S48, sending the updated early warning strategy to the terminal.

[0087] Exemplarily, next, the server 120 sends the updated warning strategy to the terminal 110. Thus, the terminal 110 can continue to detect the safety / performance of the vehicle according to the updated warning strategy, that is, determine whether the vehicle currently has a safety / performance problem.

[0088] Exemplarily, S46 and S48 are related operations that the server 120 can perform when the warning strategy does not conform to the actual state of the vehicle; and when the state parameters obtained by the terminal 110 are incorrect, the server 120 can send an instruction to the terminal 110 to suspend the output of warning information to avoid the terminal 110 outputting invalid warning information multiple times and disturbing the user.

[0089] For example, in the memory usage example described in S44, the server 120 may send an instruction to the terminal 110 to suspend outputting the first warning information to avoid the terminal 110 outputting invalid warning information about memory usage multiple times and disturbing the user.

[0090] Optionally, after determining that the first warning information is invalid warning information, the server 120 may record the number of times the first warning information is determined to be invalid warning information (i.e., the number of times the first warning information is obtained). Further, the server 120 may set a first preset threshold, and when the number of times the first warning information is determined to be invalid warning information reaches the first preset threshold (i.e., the number of times the first warning information is obtained reaches the first preset threshold), the current warning strategy is updated, or an instruction to suspend outputting warning information is sent to the terminal 110.

[0091] In an exemplary embodiment, if the server 120 determines that the vehicle currently has a safety / performance problem based on the current state parameters and the warning strategy, the first warning information is determined to be valid warning information. Specifically, the server 120 can determine the warning level corresponding to each state parameter according to the warning strategy to determine whether the current state of the vehicle has a safety / performance problem. For example, when the warning level is lower than the preset warning level, it is determined that the current state of the vehicle does not have a safety / performance problem.

[0092] For example, Figure 3a As shown, the memory usage obtained by the terminal 110 is 80%. Assuming that the actual memory usage obtained by the server 120 is 80%, it means that the information obtained by the terminal 110 is accurate. Therefore, the server 120 can determine that the current memory usage of the vehicle is in an urgent state (the vehicle currently has safety / performance problems) according to the early warning strategy, and determine that the first early warning information output by the terminal 110 is valid early warning information.

[0093] Alternatively, if the server 120 determines that the vehicle currently has a safety / performance problem based on the current state parameters, the historical state parameters, and the warning strategy, the first warning information is determined to be valid warning information. Specifically, the server 120 can combine the historical state parameters and the current state parameters to determine whether the warning strategy is reasonable, that is, to determine whether the warning strategy is in line with the actual situation of the vehicle. If the warning strategy is in line with the actual situation of the vehicle, it can be determined that the vehicle currently has a safety / performance problem, and the first warning information is valid warning information.

[0094] For example, Figure 3bAs shown, the terminal 110 determines that the vehicle currently needs maintenance according to the early warning strategy. Assuming that the server 120 determines that the user's actual use frequency of the vehicle is relatively high according to the historical status parameters of the vehicle, it means that the maintenance cycle set in the early warning strategy is applicable to the actual use frequency of the vehicle, that is, the current early warning strategy is in line with the actual situation of the vehicle. Therefore, the server 120 can determine that the vehicle currently needs maintenance (the vehicle currently has safety / performance problems), and determine that the first early warning information output by the terminal 110 is a valid early warning information.

[0095] In addition to processing invalid warning information, we can also pay attention to whether the user processes the valid warning information, that is, whether the user processes the current problem of the vehicle after receiving the valid warning information.

[0096] Therefore, after the server 120 determines that the first warning information is valid warning information, the number of times the first warning information is determined to be valid warning information (ie, the number of times the first warning information is obtained) may be recorded.

[0097] Figure 5 This is a flowchart of an example of processing effective warning information provided by this application.

[0098] S50: The server determines that the number of times the first warning information is obtained reaches a second preset threshold.

[0099] S52: Send a first instruction to the terminal.

[0100] Furthermore, the server 120 may set a second preset threshold, and when it is determined that the number of times the first warning information is obtained reaches the second preset threshold, send a first instruction to the terminal 110. The first instruction includes an instruction to generate a second warning information, and the warning level corresponding to the second warning information is higher than the warning level corresponding to the first warning information.

[0101] S54: The terminal generates second warning information in response to the first instruction.

[0102] Exemplarily, the terminal 110 responds to the first instruction and generates a second warning message. Since the warning level corresponding to the second warning message is higher than the warning level corresponding to the first warning message, the prompt intensity of the warning message can be increased to strengthen the reminder to the user.

[0103] In an exemplary embodiment, if terminal 110 outputs a valid first warning message, but the user feels disturbed by the warning message, or the user believes that the first warning message is actually invalid, then the user can also choose to ignore the first warning message output by terminal 110 and further mark it as a false alarm.

[0104] Exemplarily, the user may click on a button such as "Ignore" or "False Alarm" in the display interface of the terminal 110. Thus, the terminal 110 sends information to the server 120 that the first warning is ignored and / or marked as a false alarm, and thus, the server 120 may send a second instruction to the terminal 110, wherein the second instruction includes an instruction to stop generating the first warning information, so as to instruct the terminal 110 to stop sending the first warning information. Furthermore, the server 120 may also send a third instruction to the terminal, so that the terminal 110 responds to the third instruction and generates a third warning information with a warning level lower than the first warning information, so as to avoid disturbing the user.

[0106] In an exemplary embodiment, the overall implementation of the vehicle safety warning method provided by the present application is as follows:

[0107] S60, the terminal obtains current state parameters of the vehicle.

[0108] S61, the terminal determines whether there is a safety problem with the vehicle at present.

[0109] Exemplarily, after acquiring the current state parameters of the vehicle, the terminal 110 determines whether the vehicle currently has a safety problem based on the current state parameters and the early warning strategy. If the vehicle currently has a safety problem, S62 is executed; if the vehicle currently does not have a safety problem, the process ends.

[0110] Optionally, for implementations of S60 to S61, please refer to Figure 1 to Figure 3b The relevant description in the illustrated embodiment will not be repeated here.

[0111] S62: When there is a safety problem with the vehicle, the terminal outputs a first warning message.

[0113] Optionally, please refer to the specific implementation method Figure 4 The relevant description of S40 will not be repeated here.

[0114] S63, the server determines whether there is a safety problem with the vehicle at present.

[0115] Exemplarily, after that, the server 120 further determines whether the vehicle currently has a safety problem based on the current state parameters, historical state parameters and other data. If the vehicle currently has a safety problem, S67 is executed; if the vehicle currently does not have a safety problem, S64 is executed.

[0116] S64: When there is no safety problem with the vehicle at present, the server determines that the first warning information is invalid warning information.

[0117] Optionally, for specific implementations of S63 to S64, please refer to Figure 4 The relevant description of S44 will not be repeated here.

[0118] S65: The server determines whether the number of invalid warnings reaches a first preset threshold.

[0119] For example, if the server 120 determines that the first warning information is invalid warning information, it can further determine whether the number of invalid warnings reaches a first preset threshold. If the number of invalid warnings reaches the first preset threshold, S66 is executed; if the number of invalid warnings does not reach the first preset threshold, the process ends.

[0120] S66: When the number of invalid warnings reaches a first preset threshold, the server causes the terminal to stop issuing warnings and updates the warning strategy.

[0121] Exemplarily, if the number of invalid warnings reaches a first preset threshold, the server 120 may cause the terminal 110 to stop issuing warnings; alternatively, the server 120 may update the warning strategy and send the updated warning strategy to the terminal 110 .

[0122] Optionally, the implementation of S65 to S66 can be found in Figure 4 The relevant description of S46 in the above description will not be repeated here.

[0123] S67, when the vehicle currently has a safety problem, the server determines that the first warning information is valid warning information.

[0124] S68: The server determines whether the number of effective warnings reaches a second preset threshold.

[0125] Exemplarily, if the server 120 determines that the first warning information is valid warning information, it can further determine whether the number of valid warnings reaches the second preset threshold. If the number of valid warnings reaches the second preset threshold, S69 is executed; if the number of valid warnings does not reach the second preset threshold, the process ends.

[0126] Optionally, please refer to the specific implementation method Figure 5 The relevant description of S50 will not be repeated here.

[0127] S69: When the number of effective warnings reaches a second preset threshold, the server enables the terminal to upgrade the warning level.

[0128] Exemplarily, if the number of effective warnings reaches a second preset threshold, the server 120 may enable the terminal 110 to upgrade the warning level.

[0129] Optionally, please refer to the specific implementation method Figure 5 The relevant description of S54 in the specification will not be repeated here.

[0130] S610: User manually ignores and / or marks a false alarm.

[0131] S611: The server stops the terminal from issuing warnings and reduces the warning level.

[0132] Exemplarily, if the user actively ignores the warning information output by the terminal 110 and / or marks it as a false alarm, the server 120 can stop the terminal 110 from issuing a warning; further, the server 120 can also reduce the warning level of the warning information; thereby, disturbing the user can be avoided.

[0133] Through the above scheme, the present application can obtain various status parameters related to vehicle safety / performance, and perform safety / performance evaluation on the vehicle according to the warning strategy based on the obtained status parameters, and output warning information. Furthermore, the validity of the output warning information can be verified; in the case where the warning information is invalid, the warning strategy is optimized to avoid repeatedly outputting invalid warning information and disturbing the user; and, in the case where the warning information is valid and the valid warning information is output multiple times, it indicates that the user has not dealt with the corresponding safety / performance problem, and the prompt intensity of the warning information can be increased, thereby further prompting the user to deal with it in time.
