Description

TECHNICAL FIELD

[0002] In a conventional vehicle safety / performance detection mode (for example, vehicle network status, maintenance cycle, power, oil, tire pressure, vehicle air quality, and air humidity, etc.), a user needs to regularly go to a car repair shop to check the relevant status of the vehicle in various aspects. However, in this way, the user cannot immediately know the safety / performance status of the vehicle, nor can the user know the specific relevant data. In other words, the user cannot know whether the safety / performance of the vehicle has a problem and which aspects have the problem at any time.

[0003] In this way, if the safety / performance of the vehicle suddenly has a problem and the user cannot know it in time, the vehicle may be damaged, and the user may also have a safety risk.

[0038] For the purposes of the present application, the technical solutions and advantages will be more apparent from the following detailed description of the embodiments of the present application, taken in conjunction with the accompanying drawings.

[0039] The following description refers to the accompanying drawings. Unless otherwise indicated, like numbers in the various drawings of the accompanying drawings denote like or similar elements. The following detailed description does not provide design limitations or suggestions to the embodiments described in the example embodiments. Instead, they are merely examples of devices and methods consistent with some aspects of the present application, as described in the appended claims.

[0040] In the description of the present application, it should be understood that the terms "first", "second", and the like are used only for the purpose of description, and cannot be understood as indicating or implying relative importance. For those skilled in the art, the specific meaning of the above terms in the present application can be understood in specific circumstances. In addition, in the description of the present application, "multiple" means two or more, unless otherwise specified. The "and / or" describes the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases: A alone, A and B together, and B alone. The character " / " generally represents a "or" relationship between the associated objects.

[0041] In the related art, the traditional vehicle safety / performance detection method cannot enable the user to know the safety / performance problem of the vehicle at any time, therefore, the existing vehicle is configured with a related monitoring system to feed back the data related to the safety of the vehicle to the user in real time, and to perform corresponding warning when the vehicle has a safety problem. However, the method for warning the safety of the vehicle in the prior art still needs to be further improved.

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

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

[0044] In the example embodiments, asFigure 1 As shown, the vehicle safety warning method provided by the present application can be applied to a vehicle safety warning system 100. The vehicle safety warning system 100 comprises a terminal 110 and a server 120. Among them, the terminal 110 can be a vehicle-mounted terminal in a vehicle, and various application programs (for example: application program 1, application program 2, application program 3) can be configured in the vehicle-mounted terminal to realize corresponding functions and interactions with the user; the server 120 is a computer that establishes a communication connection with the terminal 110, which can be a physical server or a cloud server. Figure 2 As shown, the terminal 110 can be a vehicle-mounted terminal in a vehicle, and various application programs (for example: application program 1, application program 2, application program 3) can be configured in the vehicle-mounted terminal to realize corresponding functions and interactions with the user; the server 120 is a computer that establishes a communication connection with the terminal 110, which can be a physical server or a cloud server.

[0045] The terminal 110 can obtain various state parameters related to the safety / performance of the vehicle through the controller area network (CAN) in the vehicle. Among them, the state parameters can include: parameters related to the performance of the terminal 110 (for example: memory usage, CPU utilization, disk transmission rate, network throughput, etc.), vehicle maintenance state, remaining power or oil of the vehicle, tire pressure of the vehicle tire, air quality and air humidity in the vehicle, etc.

[0046] The terminal 110 can generate and output the safety warning information of the vehicle (denoted as: first warning information) according to the warning strategy and the above-mentioned state parameters, and the server 120 can further judge the validity of the first warning information (that is, whether the vehicle indeed has a safety / performance problem), and in the case of invalid warning information, 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 as to realize the above-mentioned functions of obtaining state parameters, interacting with the server 120 and outputting warning information through the application program, and realizing the interaction with the user through the visual interface of the application program.

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

[0049] In an exemplary embodiment, the terminal 110 can be pre-configured with a warning strategy of different state parameters.

[0050] The early warning strategy can include a mapping relationship between the state parameter and the early warning level, i.e., the state parameter has a corresponding early warning level at different values. More specifically, the early warning strategy can include a mapping relationship between the state parameter, the state score, the state level, and the early warning level, i.e., the state parameter has a corresponding state score at different values, different state scores have a corresponding state level, and different state levels have a corresponding early warning level. In addition, the early warning strategy can also include a mapping relationship between the preset early warning level, the early warning level, the early warning information, and the prompt strength, i.e., after the early warning level reaches the preset early warning level, the corresponding early warning information is output, and different early warning information has different prompt strengths.

[0051] For example, the early warning level can be divided into three levels (high, medium, and low) (or one, two, or three levels, or other classification methods, which are not limited in the embodiment).

[0052] In addition, the preset early warning level can be set to medium (i.e., the early warning information is output when the early warning level is high or medium), the early warning information when the early warning level is one is a voice prompt, and the prompt information is displayed in the terminal 110 (high prompt strength), and so on; the early warning information when the early warning level is two is to display the prompt information in the terminal 110 and send the prompt information to the user's mobile phone (medium / low prompt strength), and so on.

[0053] In addition, the state level corresponding to the early warning level can be set to good (corresponding to low early warning level), poor (corresponding to medium early warning level), and urgent treatment (corresponding to high early warning level).

[0054] In addition, the state level corresponding to the state score can be set to 100-70 points for a good state, 69-40 points for a poor state, and 39-0 points for an urgent treatment state.

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

[0056] For the memory usage (100%-0%) of the terminal 110, the mapping relationship between the memory usage and the state score / state level can be set as follows: the memory usage in the interval of 100%-70% corresponds to the state score of 0-39 points (urgent treatment state); the memory usage in the interval of 69%-40% corresponds to the state score of 40-69 points (poor state); and the memory usage in the interval of 39%-0% corresponds to the state score of 70-100 points (good state).

[0057] For the vehicle maintenance state, the mapping relationship between the state score (which can be calculated according to the number of days since the last maintenance) / state level can be set as follows: if the vehicle has been maintained for less than or equal to 2 months since the last maintenance, the corresponding state score is 100-80 points (good state); if the vehicle has been maintained for 3-6 months since the last maintenance, the corresponding state score is 79-40 points (poor state); if the vehicle has been maintained for more than or equal to 7 months since the last maintenance, the corresponding state score is 39-0 points (urgent treatment state).

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

[0059] It should be noted that the related content set in the above early warning strategy is an example, and the early warning strategy can be flexibly configured according to actual conditions, which is not limited in this embodiment.

[0060] In an exemplary embodiment, after the terminal 110 obtains the current state parameter (which can be one or multiple) of the vehicle, it can determine the early warning level corresponding to each state parameter according to the early warning strategy to determine whether the current state of the vehicle has a safety / performance problem and whether the corresponding early warning information needs to be generated and output.

[0061] For example, when the early warning level reaches or is higher than the preset early warning level, it is determined that the current state of the vehicle has a safety / performance problem, and the early warning information with the prompt strength corresponding to the early warning level is output; when the early warning level is lower than the preset early warning level, it is determined that the current state of the vehicle does not have a safety / performance problem, and the early warning information can not be output.

[0062] Optionally, the terminal 110 can also output a solution for handling the current safety / performance problem of the vehicle while outputting the early warning information, to help the user effectively solve the current safety / performance problem of the vehicle.

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

[0064] ReferenceFigure 3a and Figure 3b a schematic diagram of the first warning information output by the terminal.

[0065] For example, assuming that the terminal 110 obtains the current memory usage of the vehicle as 80%, the terminal 110 can determine, according to the above-mentioned warning strategy (still taking the content of the above-mentioned warning strategy as an example), that the current memory usage of the vehicle is in the interval of 100% to 70%, and the corresponding state score is 20 points, in the state of urgent treatment, and the corresponding warning level is the high warning level (higher than the preset warning level). Then the terminal 110 can output the first warning information with high prompt intensity, for example, can output voice prompt (for example, "your memory usage is too high, please handle it in time"), and output display prompt information on the display interface, etc., to inform the user that the current memory usage of the terminal 110 is very high, and it is suggested to handle it immediately. Alternatively, the terminal 110 can also give relevant processing scheme, for example: end some processes in the terminal 110, close some unnecessary services, etc.

[0066] Assuming that the terminal 110 obtains the current vehicle maintenance state of the vehicle as 3 months away from the last maintenance, the terminal 110 can determine, according to the above-mentioned warning strategy, that the current vehicle maintenance state of the vehicle corresponds to the state score in the interval of 40 to 69 points, in the poor state, and the corresponding warning level is the medium warning level (reaching the preset warning level). Then the terminal 110 can output the first warning information with medium prompt intensity, for example, can display prompt information in the display interface, or send prompt information to the user's mobile phone, etc., to inform the user that the vehicle is currently far away from the last maintenance, and it is suggested to maintain as soon as possible, etc. Alternatively, the terminal 110 can also give relevant processing scheme, for example: find the nearest car repair shop for the user, establish vehicle maintenance schedule and reminder for the user, etc.

[0067] Figure 4 is an interaction diagram of a vehicle safety warning method provided by the present application.

[0068] S40, when detecting that the vehicle has safety problems according to the current state parameters of the vehicle according to the warning strategy, output the first warning information.

[0069] For example, if the terminal 110 analyzes the current state parameters of the vehicle obtained according to the above-mentioned warning strategy, and determines that the vehicle currently has safety / performance problems, the first warning information is generated and output.

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

[0071] It can be understood that due to sensor errors or network delays, etc., the state parameters obtained by the terminal 110 can be inaccurate, or the early warning strategy in the terminal 110 cannot well conform to the actual situation of the vehicle, so that the first early warning information output by the terminal 110 is invalid early warning information; that is, the terminal 110 makes a judgment that the vehicle has a safety / performance problem, but in fact the vehicle does not have a safety / performance problem, so the first early warning information output by the terminal 110 is invalid early warning information.

[0072] For example, as shown in FIG. 8, it is assumed that the terminal 110 obtains the usage of the memory of the vehicle at a certain time as 80%, and outputs the first early warning information with a medium prompt strength according to the early warning strategy, but in fact the usage of the memory of the vehicle is 30%. According to the above early warning strategy, it can be determined that the current usage of the memory does not exist a problem, and the first early warning information output by the terminal 110 is invalid early warning information. Figure 3a For example, as shown in FIG. 9, it is assumed that the terminal 110 outputs the first early warning information with a medium prompt strength according to the early warning strategy when the vehicle has passed the last maintenance period for 3 months; but in combination with the recent use frequency of the vehicle, the use frequency of the vehicle is very low (for example, only used once in the past 3 months), so the vehicle does not need to be maintained at present, and it can be determined that the current maintenance state of the vehicle does not actually exist a problem, and the first early warning information output by the terminal 110 is invalid early warning information.

[0073] Figure 3b Therefore, after outputting the first early warning information, the terminal 110 can obtain the current state parameters of the vehicle again, and send the above-mentioned re-acquired state parameters and the first early warning information to the server 120.

[0074] S44, according to the current state parameters of the vehicle and the historical state parameters of the vehicle, it is determined that the vehicle currently does not exist a safety problem; the first early warning information is determined as invalid early warning information.

[0075] For example, the server 120 can determine whether the vehicle currently exists a safety / performance problem according to the above state parameters and the above early warning strategy. If the server 120 determines that the vehicle currently does not exist a safety / performance problem according to the current state parameters and the early warning strategy, the first early warning information is determined as invalid early warning information.

[0076] For example, the server 120 can determine whether the vehicle currently exists a safety / performance problem according to the above state parameters and the above early warning strategy. If the server 120 determines that the vehicle currently does not exist a safety / performance problem according to the current state parameters and the early warning strategy, the first early warning information is determined as invalid early 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 the current state of the vehicle has a safety / performance problem. For example, when the warning level reaches or is higher than a preset warning level, it is determined that the current state of the vehicle has a safety / performance problem. The specific determination manner can refer to the related description of determining whether the current state of the vehicle has a safety / performance problem by the terminal 110 in the above embodiments, which will not be described here.

[0078] For example, as shown in FIG. 8, the memory usage obtained by the terminal 110 is 80%. Assuming that the actual memory usage obtained by the server 120 is 30%, it indicates 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 problem) according to the warning strategy, and determine that the first warning information output by the terminal 110 is invalid warning information. Figure 3a

[0079] For example, as shown in FIG. 8, the memory usage obtained by the terminal 110 is 80%. Assuming that the actual memory usage obtained by the server 120 is 30%, it indicates 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 problem) according to the warning strategy, and determine that the first warning information output by the terminal 110 is invalid warning information.

[0080] Therefore, the server 120 can also determine whether the current state of the vehicle has a safety / performance problem according to the obtained current state parameter, historical state parameter and warning strategy. If the server 120 determines that the current state of the vehicle has no safety / performance problem according to the current state parameter, historical state parameter and warning strategy, it is determined that the first warning information is invalid warning information.

[0081] Specifically, the server 120 can determine whether the warning strategy is reasonable in combination with the historical state parameter and the current state parameter, that is, determine whether the warning strategy conforms to the actual situation of the vehicle. If the warning strategy does not conform to the actual situation of the vehicle, it is determined that the current state of the vehicle has no safety / performance problem, and the first warning information is invalid warning information.

[0082] For example, as shown in FIG. 8, the memory usage obtained by the terminal 110 is 80%. Assuming that the actual memory usage obtained by the server 120 is 30%, it indicates 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 problem) according to the warning strategy, and determine that the first warning information output by the terminal 110 is invalid warning information. Figure 3b ​As shown, the terminal 110 determines that the vehicle currently needs to be maintained according to the early warning strategy. Assuming that the server 120 determines that the actual use frequency of the vehicle by the user is not high according to the historical state parameters of the vehicle, it is indicated that the vehicle does not need to be maintained according to the current maintenance period, that is, the current early warning strategy does not well conform to the actual situation of the vehicle. Therefore, the server 120 can determine that the vehicle currently does not need to be maintained (the vehicle currently does not have a safety / performance problem) 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] For example, in the case where the early warning strategy does not conform to the actual state of the vehicle, the server 120 can update the current early warning strategy according to the current state parameters and the historical state parameters and the like. Specifically, when updating the early warning strategy, the server 120 can determine the critical state parameters corresponding to the safety problem of the vehicle according to the current state parameters and the historical state parameters and the like of the vehicle, and update the early warning strategy according to the critical state parameters.

[0085] For example, in the example of vehicle maintenance described in S44, the server 120 can determine the next maintenance time of the vehicle, that is, the critical state parameters for early warning of the maintenance state, according to the vehicle use frequency, the wear condition of each component and the like in the historical state parameters, for example, the critical state parameters for vehicle maintenance are set to 12 months. In this way, the early warning information can be output when the vehicle has not been maintained again after 12 months from the last maintenance, so that the early warning strategy can better conform to the actual state of the vehicle.

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

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

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

[0089] For example, in the memory usage example described in S44, server 120 can send an instruction to terminal 110 to pause the output of the first warning information in order to avoid terminal 110 repeatedly outputting invalid warning information about memory usage and disturbing the user.

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

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

[0092] For example, such as Figure 3a As shown, the memory usage obtained by terminal 110 is 80%. Assuming the actual memory usage obtained by server 120 is also 80%, it indicates that the information obtained by terminal 110 is accurate. Therefore, server 120 can determine, based on the warning strategy, that the vehicle's current memory usage is in a state of urgent need for processing (the vehicle currently has a safety / performance issue), and determine that the first warning information output by terminal 110 is a valid warning.

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

[0094] For example, such as Figure 3bAs shown, the terminal 110 determines that the vehicle currently needs to be maintained according to the early warning strategy. It is assumed that the server 120 determines that the actual use frequency of the vehicle by the user is relatively high according to the historical state parameters of the vehicle, which indicates that the maintenance period set in the early warning strategy is suitable for the actual use frequency of the vehicle, that is, the current early warning strategy conforms to the actual situation of the vehicle. Therefore, the server 120 can determine that the vehicle currently needs to be maintained (the vehicle currently has a safety / performance problem) and determine that the first early warning information output by the terminal 110 is valid early warning information.

[0095] In addition to processing invalid early warning information, it can also be concerned whether the user has processed valid early warning information, that is, whether the user has processed the current problem of the vehicle after receiving valid early warning information.

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

[0097] Figure 5 The flowchart provided by the present application is an example of processing valid early warning information.

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

[0099] S52, the first instruction is sent to the terminal.

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

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

[0102] For example, the terminal 110 generates the second early warning information in response to the above-mentioned first instruction. Since the early warning level corresponding to the second early warning information is higher than the early warning level corresponding to the first early warning information, the prompt strength of the early warning information can be improved to strengthen the reminder to the user.

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

[0104] For example, the user can click the "ignore" or "false alarm" button in the display interface of the terminal 110. Thus, the terminal 110 sends the information that the first warning is ignored and / or marked as a false alarm to the server 120, so that the server 120 can send a second instruction to the terminal 110, which includes the instruction to stop generating the first warning information, to instruct the terminal 110 to stop sending the first warning information. Further, the server 120 can 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 lower warning level than the first warning information, to avoid disturbing the user.

[0105] Figure 6 is a flowchart of another example vehicle safety warning method provided by the present application.

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

[0107] S60, the terminal acquires the current state parameter of the vehicle.

[0108] S61, the terminal determines whether the vehicle currently has a safety problem.

[0109] For example, after the terminal 110 acquires the current state parameter of the vehicle, it determines whether the vehicle currently has a safety problem according to the current state parameter and the warning strategy. If the vehicle currently has a safety problem, S62 is performed; if the vehicle currently does not have a safety problem, the process ends.

[0110] Alternatively, the implementation of S60 to S61 can refer to the related description in the embodiment shown in Figures 1 to 3b , which will not be repeated here.

[0111] S62, in the case where the vehicle currently has a safety problem, the terminal outputs a first warning information.

[0112] For example, if the terminal 110 determines that the vehicle currently has a safety problem, it outputs a first warning information.

[0113] Alternatively, for specific implementation, please refer to the related description of S40 in Figure 4 , which will not be repeated here.

[0114] S63, the server determines whether the vehicle currently has a safety problem.

[0115] For example, then, the server 120 further determines whether the vehicle currently has a safety problem according to the current state parameter, historical state parameter and other data. If the vehicle currently has a safety problem, S67 is performed; if the vehicle currently does not have a safety problem, S64 is performed.

[0116] S64, in the case that the vehicle currently does not have a safety problem, the server determines that the first warning information is invalid warning information.

[0117] Optionally, the specific implementation of S63 to S64 can refer to the related description of S44 in Figure 4 , which will not be described here again.

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

[0119] Illustratively, 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. In the case that the number of invalid warnings reaches the first preset threshold, S66 is performed; in the case that the number of invalid warnings does not reach the first preset threshold, the process ends.

[0120] S66, in the case that the number of invalid warnings reaches the first preset threshold, the server makes the terminal stop warning and updates the warning strategy.

[0121] Illustratively, if the number of invalid warnings reaches the first preset threshold, the server 120 can make the terminal 110 stop warning; or the server 120 can update the warning strategy and send the updated warning strategy to the terminal 110.

[0122] Optionally, the specific implementation of S65 to S66 can refer to the related description of S46 in Figure 4 , which will not be described here again.

[0123] S67, in the case that 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 valid warnings reaches a second preset threshold.

[0125] Illustratively, 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 a second preset threshold. In the case that the number of valid warnings reaches the second preset threshold, S69 is performed; in the case that the number of valid warnings does not reach the second preset threshold, the process ends.

[0126] Optionally, the specific implementation can refer to the related description of S50 in Figure 5 , which will not be described here again.

[0127] S69, in the case that the number of valid warnings reaches the second preset threshold, the server makes the terminal upgrade the warning level.

[0128] For example, if the number of valid early warnings reaches a second preset threshold, the server 120 can cause the terminal 110 to upgrade the early warning level.

[0129] Alternatively, for specific implementation manners, please refer to the related description of S54 in Figure 5 , which will not be repeated here.

[0130] S610, the user manually ignores, and / or, marks false positives.

[0131] S611, the server causes the terminal to stop early warning and reduce the early warning level.

[0132] For example, if the user actively ignores the early warning information output by the terminal 110 and / or marks it as a false positive, the server 120 can cause the terminal 110 to stop early warning; further, the server 120 can also reduce the early warning level of the early warning information; thus, it can avoid disturbing the user.

[0133] The present application can obtain various state parameters related to vehicle safety / performance, and perform safety / performance evaluation on the vehicle according to the obtained state parameters according to the early warning strategy, and output early warning information. Further, the effectiveness of the output early warning information can be verified; in the case of invalid early warning information, the early warning strategy is optimized, so as to avoid repeatedly outputting invalid early warning information and disturbing the user; and in the case of valid early warning information and multiple outputs of the valid early warning information, it is indicated that the user has not processed the corresponding safety / performance problem, so as to improve the prompt strength of the early warning information, so as to further prompt the user to process in time.

1. A vehicle safety early warning method, characterized in that, The method includes: The system acquires a first warning message and the vehicle's current status parameters. The first warning message is generated when a safety problem is detected in the vehicle based on the vehicle's current status parameters and a warning strategy. The first warning message is used to alert the user that there is a safety problem with the vehicle. Based on the vehicle's current status parameters and its historical status parameters, it is determined that the vehicle currently does not have any safety issues. The first warning message is determined to be an invalid warning message; The number of times the first warning message is determined to be an invalid warning message; When the number of times the first warning information is an invalid warning information reaches a first preset threshold, the critical state parameters corresponding to when the vehicle has a safety problem are determined based on the current state parameters of the vehicle and the historical state parameters of the vehicle. The early warning strategy is updated based on the critical state parameters, and the updated early warning strategy is sent.

2. The method according to claim 1, characterized in that, The early warning strategy includes the mapping relationship between status parameters and early warning levels; The first warning information is generated when the warning level corresponding to the current state parameter of the vehicle is higher than the preset warning level. The warning level corresponding to the current state parameter of the vehicle is determined based on the current state parameter of the vehicle and the mapping relationship.

3. The method according to claim 2, characterized in that, The warning level is proportional to the intensity of the first warning information; the method further includes: Based on the vehicle's current status parameters and its historical status parameters, it is determined that the vehicle currently has a safety issue. The first warning message is determined to be a valid warning message; If the number of times the first warning information is obtained reaches a second preset threshold, a first instruction is sent, the first instruction including an instruction to generate a second warning information, the warning level corresponding to the second warning information being higher than the warning level corresponding to the first warning information.

4. The method according to claim 3, characterized in that, The method further includes: It was determined that the first warning message was marked as a false alarm by the user; Send a second instruction, which includes an instruction to stop generating the first warning information.

5. The method according to any one of claims 1 to 4, characterized in that, The status parameters are used to represent the safety status of the vehicle.
