[0053] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0054] Figure 1 FIG. 1 is a schematic diagram of an implementation environment of an exemplary embodiment of the present disclosure. Figure 1 As shown, the implementation environment may include a terminal 10 and a background system 20. For example, the terminal 10 may be a vehicle-mounted terminal or a handheld terminal.

[0055] A first signal transceiver module may be provided in the terminal 10, and correspondingly, a second signal transceiver module may be provided in the background system 20. The first signal transceiver module and the second signal transceiver module may establish a communication connection to allow signal transmission between the terminal 10 and the background system 20. Exemplarily, the terminal 10 and the background system 20 can communicate with each other by using any of the following methods, for example, Bluetooth, 2G (2nd-Generation wireless telephone technology), 3G (3rd-Generation wireless telephone technology), 4G (4th-Generation wireless telephone technology), 5G (5th-Generation wireless telephone technology), NB-IOT (Narrow Band Internet of Things), eMTC (LTE enhanced MTO), LTE (Long Term Evolution), LTE-A (LTE-Advanced), Near Field Communication (NFC), WiFi, etc.

[0056] In practical applications, the terminal 10 may often move with the vehicle, and considering convenience and timeliness, preferably, the terminal 10 and the background system 20 can communicate via 4G. In this way, the first signal transceiver module and the second signal transceiver module can both be 4G communication modules.

[0057] Combined with the following Figures 2 to 9 A vehicle status monitoring method applied to the above implementation environment is described.

[0058] Figure 2 1 is a flow chart of a vehicle status feedback method applied to a terminal provided by an exemplary embodiment of the present disclosure. Figure 2 The embodiment of the present disclosure provides a method for applying to a terminal (for example, Figure 1 A method for feedback of vehicle status of a terminal 10) in the vehicle, the method may include steps S11 to S13.

[0059] In step S11, first parameter information of the charging component at the current sampling moment is obtained according to a preset sampling period.

[0060] In step S12, judging whether the charging component fails according to the first parameter information, and storing the first parameter information in a cache queue, wherein the cache queue is used to store a first preset number of parameter information;

[0061] In step S13, when it is determined that a charging component fails based on the first parameter information, second parameter information of a second preset number of charging components is continuously obtained, and the obtained second parameter information is cached in a cache queue, and all parameter information in the cache queue is sent to the background system, wherein the second preset number is smaller than the first preset number.

[0062] In this way, all parameter information in the cache queue includes both the first parameter information before the charging component fails and the second parameter information after the charging component fails, so as to fully record the status of the charging component before and after the failure, which is convenient for accurate troubleshooting. At the same time, after the charging component fails, the terminal sends all parameter information in the cache queue to the background system, and then starts the troubleshooting process in advance to shorten the maintenance cycle and reduce the impact of the charging component failure on the user. In addition, after detecting a charging failure, the abnormal operating time of the vehicle can be reduced, which is beneficial to driving safety and avoids further expansion of vehicle damage.

[0063] Figure 3 FIG. 1 is a schematic diagram of caching parameter information when acquiring parameter information of a charging component, shown in an exemplary embodiment of the present disclosure. Figure 3 , Figure 3 The arrow direction in the figure is the cache direction of the cache queue 30. When the charging component fails, the first parameter information changes accordingly, so that the charging component can be determined to have failed according to the first parameter information. Figure 3 In the example, the first parameter information at the fault point 40 changes significantly, so that the charging component fault can be determined. After the charging component fault is determined, the second parameter information of the second preset number of charging components is continuously obtained, and the obtained second parameter information is cached in the cache queue 30.

[0064] After the second preset number of second parameter information and the third preset number of first parameter information are cached in the cache queue 30, the terminal sends all parameter information in the cache queue to the background system (for example, it can be Figure 1 The backend system 20 in the embodiment, wherein the sum of the third preset number and the second preset number is equal to the first preset number.

[0065] Figure 4 1 is a flow chart of a vehicle status feedback method applied to a background system provided by an exemplary embodiment of the present disclosure. Figure 4The embodiment of the present disclosure also provides a vehicle status feedback method, which is applied to a background system (for example, Figure 1 In the background system 20), the method includes step S21 and step S22.

[0066] In step S21, a cache queue sent by a receiving terminal is used to store a first preset number of parameter information, wherein the first preset number of parameter information includes a second preset number of second parameter information, wherein the second preset number is smaller than the first preset number;

[0067] In step S22, maintenance guidance information is obtained by analyzing all parameter information of the cache queue.

[0068] In this way, all parameter information in the cache queue includes both the first parameter information before the charging component fails and the second parameter information after the charging component fails, so as to fully record the status of the charging component before and after the failure, which is convenient for accurate troubleshooting. At the same time, after the charging component fails, the terminal sends all parameter information in the cache queue to the background system, and the background system can analyze and obtain maintenance guidance information based on all parameter information in the cache queue, and can quickly determine the maintenance guidance information to reduce the impact of the charging component failure on the user.

[0069] Figure 5 FIG. 1 is a flow chart of a vehicle status feedback method provided by an exemplary embodiment of the present disclosure. Figure 5 , an embodiment of the present disclosure provides a vehicle status feedback method, which may include steps S31 to S38.

[0070] In step S31, the terminal obtains first parameter information of the charging component at the current sampling moment according to a preset sampling period;

[0071] In step S32, the terminal determines whether the charging component fails according to the first parameter information, and stores the first parameter information in a cache queue;

[0072] In step S33, when the terminal determines that a charging component fails according to the first parameter information, the terminal continuously obtains second parameter information of a second preset number of charging components, and caches the obtained second parameter information in a cache queue.

[0073] In step S34, the terminal sends all parameter information in the cache queue to the background system.

[0074] In step S35, the background system receives all parameter information of the cache queue sent by the terminal.

[0075] In step S36, the background system analyzes all parameter information in the cache queue to obtain maintenance guidance information.

[0076] In step S37, the background system sends the maintenance instruction information to the terminal.

[0077] In step S38, the terminal receives the maintenance instruction information sent by the background system.

[0078] In this way, when a charging component fails, the terminal's cache queue can cache the first parameter information before the charging component fails and the second parameter information after the charging component fails, and send all the parameter information in the cache queue to the background system, so that the background system can analyze all the parameter information in the cache queue to obtain maintenance guidance information. In this way, the fault troubleshooting process can be started in advance to shorten the maintenance cycle and reduce the impact of the charging component failure on users.

[0079] After the terminal receives the maintenance guidance information sent by the background system, the user can accurately know the fault condition of the charging component, avoid unnecessary parts replacement due to inaccurate fault detection by maintenance personnel, and reduce unnecessary expenses for users.

[0080] At the same time, after a charging fault is detected, the vehicle's abnormal operating time can be reduced, which is beneficial to driving safety and avoids further expansion of vehicle damage.

[0081] Exemplarily, the terminal may be a vehicle-mounted terminal. After the terminal receives the maintenance guidance information sent by the background system, the terminal may control the dashboard in the vehicle to display the analysis guidance information to prompt the user.

[0082] In another possible implementation, the terminal may be a handheld terminal, and the handheld terminal may communicate with the vehicle-mounted terminal via Bluetooth to obtain the first parameter information and the second parameter information of the charging component. In this way, the upgrade cost of the vehicle may be reduced, and promotion may be facilitated.

[0083] In a possible implementation, the background system may include a server and a monitoring background, and the monitoring background and the terminal send parameter information and maintenance guidance information through the server.

[0084] Exemplarily, the maintenance guidance information includes at least one of the following: a name of a faulty component, a maintenance guidance price of the faulty component, a recommended maintenance point, and an estimated maintenance time.

[0085] The name of the faulty component can let the user know the faulty charging component, so that the user can have a relatively reasonable expectation of the impact of the faulty charging component, which is convenient for the user to adjust the driving strategy of the vehicle in time. For example, the vehicle can also prompt the user with the possible impact based on the name of the faulty component.

[0086] The repair guidance price, recommended repair point and estimated repair time of the faulty components help users choose a reasonable repair strategy and plan their travel during vehicle maintenance.

[0087] Exemplarily, the charging component may include a DC-DC converter, and correspondingly, the first parameter information and the second parameter information may both include at least one of the following: first voltage information for characterizing the output voltage of the DC-DC converter, first current information for characterizing the output current of the DC-DC converter, first temperature information for characterizing the temperature of the DC-DC converter, battery voltage information for characterizing the voltage of a low-voltage battery connected to the output of the DC-DC converter, step-down time information for characterizing the cumulative working time of the DC-DC converter, first maximum temperature information for characterizing the maximum temperature of the DC-DC converter during operation, and first peripheral information for characterizing the control instructions received by the DC-DC converter.

[0088] In this way, according to the first voltage information, it can be determined whether the output voltage of the DC-DC converter is normal, according to the first current information, it can be determined whether the output current of the DC-DC converter is normal, according to the first temperature information, it can be determined whether the temperature of the DC-DC converter is normal, according to the battery voltage information, the voltage of the low-voltage battery can be determined, and then it can be determined whether there is an abnormality in the low-voltage battery, according to the voltage reduction time information, the cumulative working time of the DC-DC converter can be determined, according to the first maximum temperature information, the maximum temperature of the DC-DC converter during operation can be determined, and according to the first peripheral information, the control instructions received by the DC-DC converter can be determined, for example, the control instructions sent to the DC-DC converter by the vehicle controller, or the control instructions sent to the DC-DC converter by the BMS (English: Battery Management System, Chinese: Battery Management System).

[0089] Exemplarily, the current of the low-voltage battery can be detected to determine the first current information; at the same time, the voltage value of the input terminal of the low-voltage battery can be detected to determine the first voltage information; at the same time, a temperature sensor can be set on the DC-DC converter to obtain the first temperature information and the first maximum temperature information.

[0090] Correspondingly, the terminal can determine the DC-DC converter failure through the following conditions:

[0091] When the first current information indicates that the output current of the DC-DC converter is abnormal, the first voltage information indicates that the output voltage of the DC-DC converter is normal, the first temperature information indicates that the temperature of the DC-DC converter is normal, the battery voltage information indicates that the low-voltage battery voltage is normal, and the first peripheral information indicates that the control instruction received by the DC-DC converter is normal, it is determined that the DC-DC converter is damaged.

[0092] For example, the first current information in the first parameter information corresponding to the sampling time before the fault time point 40 represents that the output current of the DC-DC converter is within a first preset value range, and the first current information in the first parameter information corresponding to the sampling time after the fault time point 40 represents that the output current of the DC-DC converter is outside the first preset value range. It can be determined that the first current information represents that the output current of the DC-DC converter is abnormal.

[0093] Exemplarily, the charging component may also be an on-board charger. Correspondingly, the first parameter information and the second parameter information may both include at least one of the following: second voltage information for characterizing the voltage at the on-board charger input terminal, second current information for characterizing the current at the on-board charger input terminal, second temperature information for characterizing the temperature of the on-board charger, resistance value information for characterizing the resistance value of the charging gun connected to the on-board charger input terminal, charging amount information for characterizing the cumulative charging amount of the on-board charger, second maximum temperature information for characterizing the maximum temperature during operation of the on-board charger, and second peripheral information for characterizing the control instructions received by the on-board charger.

[0094] The voltage at the input terminal of the on-board charger can be determined through the second voltage information, the current at the input terminal of the on-board charger can be determined through the second current information, the temperature of the on-board charger can be determined through the second temperature information, the resistance value of the charging gun connected to the input terminal of the on-board charger can be determined through the resistance value information, and then whether the charging gun has an abnormality can be determined based on the resistance value of the charging gun. The cumulative charging amount of the on-board charger can be determined through the charging amount information, the maximum temperature during the operation of the on-board charger can be determined through the second maximum temperature information, and the control instructions received by the on-board charger can be determined through the second peripheral information, for example, the control instructions sent by the vehicle controller to the charging gun, or the control instructions sent by the BMS to the on-board charger.

[0095] Correspondingly, the terminal can determine the fault of the on-board charger through the following conditions:

[0096] When the second current information indicates that the current at the input end of the on-board charger is abnormal, the second voltage information indicates that the voltage at the input end of the on-board charger is normal, the second temperature information indicates that the temperature of the on-board charger is normal, the resistance value information indicates that the resistance value of the charging gun is normal, and the second peripheral information indicates that the control instruction received by the on-board charger is normal, it is determined that the on-board charger is damaged.

[0097] For example, the second current information in the first parameter information corresponding to the sampling time before the fault time point 40 represents that the current at the input end of the vehicle charger is within the second preset value range, and the second current information in the first parameter information corresponding to the sampling time after the fault time point 40 represents that the current at the input end of the vehicle charger is outside the second preset value range. It can be determined that the second current information represents that the current at the input end of the vehicle charger is abnormal.

[0098] Exemplarily, the second parameter information may be the same as the first parameter information.

[0099] Figure 6 is a flow chart of a vehicle status feedback method provided by an exemplary embodiment of the present disclosure, Figure 7 FIG. 1 is a schematic diagram of a cache queue when a charging component is not faulty, shown in an exemplary embodiment of the present disclosure. Figure 6 and Figure 7 , an embodiment of the present disclosure further provides a vehicle status feedback method, which may include steps S41 to S48.

[0100] In step S41, the terminal obtains first parameter information of the charging component at the current sampling moment according to a preset sampling period;

[0101] In step S42, the terminal determines whether the charging component fails according to the first parameter information, and stores the first parameter information in a cache queue;

[0102] In step S43, when the terminal determines that the charging component has not failed according to the first parameter information, the terminal repeatedly obtains the third parameter information of the charging component at the next sampling moment, and stores the third parameter information at the next sampling moment in the cache queue.

[0103] In step S44, when receiving the vehicle power-off instruction, the terminal sends all parameter information in the cache queue to the background system.

[0104] In step S45, the background system receives all parameter information of the buffer queue sent by the terminal.

[0105] In step S46, the background system analyzes all the parameter information in the cache queue to obtain maintenance guidance information, where the maintenance guidance information is guidance information determined by the background system based on all the parameter information in the cache queue.

[0106] In step S47, the background system sends the maintenance guidance information to the terminal.

[0107] In step S48, the terminal receives the maintenance guidance information sent by the background system.

[0108] Through the solution of this example, when the terminal determines that the charging component has not failed based on the first parameter information, the terminal can continue to obtain the third parameter information of the charging component at multiple sampling moments. When it is determined that the vehicle power-off instruction has been received, the terminal sends all parameter information of the cache queue to the background system. Figure 4 Before receiving the vehicle power-off instruction, the cache area 30 continues to cache the third parameter information at the most recent sampling time. Since the cache queue stores the latest third parameter information of the charging component, the background system can determine the latest operating status of the charging component according to the third parameter information.

[0109] For example, the maintenance guidance information may include at least one of the following: a recommended maintenance time, recommended maintenance items, a recommended maintenance location, and an estimated maintenance price.

[0110] In this way, users can refer to the maintenance guidance information to reasonably determine the vehicle maintenance strategy, and at the same time facilitate travel planning during vehicle maintenance, reducing the impact of vehicle maintenance on users.

[0111] Exemplarily, the charging component may include a DC-DC converter. Referring to the above example, the third parameter information may include first current information, first voltage information, voltage reduction time information, first maximum temperature information, and first peripheral information. The background system may determine the current working state of the DC-DC converter according to the first voltage information, the first current information, the voltage reduction time information, the first maximum temperature information, and the first peripheral information.

[0112] For example, a correspondence between the first voltage information, the first current information, the voltage reduction time information, the first maximum temperature information and the first peripheral information and the life cycle of the DC-DC converter can be constructed, so that the position of the DC-DC converter in the current life cycle can be determined according to the first voltage information, the first current information, the voltage reduction time information, the first maximum temperature information and the first peripheral information, so as to facilitate the formulation of a maintenance and repair strategy for the DC-DC converter.

[0113] At the same time, when at least one of the first voltage information, the first current information, the first maximum temperature information and the first peripheral information is abnormal, the cause can be checked. After determining the cause, on the one hand, the working strategy of the DC-DC converter can be optimized to extend the service life of the DC-DC converter; on the other hand, it can also provide a reference for the formulation of test specifications and the design of new products, facilitating product upgrades and iterations.

[0114] Exemplarily, the charging component may include an on-board charger. Referring to the above example, the third parameter information may include second voltage information, second current information, charge amount information, second maximum temperature information, and second peripheral information. The background system may determine the operating state of the charging component according to the operating data information, which may include: determining the current operating state of the on-board charger according to the second voltage information, second current information, charge amount information, second maximum temperature information, and second peripheral information.

[0115] For example, a correspondence between the second voltage information, the second current information, the charge amount information, the second maximum temperature information and the second peripheral information and the life cycle of the on-board charger can be constructed, so that the position of the on-board charger in the current life cycle can be determined according to the second voltage information, the second current information, the charge amount information, the second maximum temperature information and the second peripheral information, so as to facilitate the formulation of a maintenance and repair strategy for the on-board charger.

[0116] At the same time, when at least one of the second voltage information, the second current information, the second maximum temperature information and the second peripheral information is abnormal, the cause can be checked.
