[0002] In the current automobile market, the fuel pump assembly is a key automobile component and is widely used in various models. The design and manufacturing of the fuel pump assembly has made certain progress, but there are still some shortcomings. For example, after long-term use, some fuel pump assemblies may cause pump core ablation due to wear of internal parts or aging of materials. This ablation phenomenon will not only affect the normal operation of the fuel pump, but also cause damage to other components in the fuel system, thereby affecting the performance of the entire vehicle; in addition, the poor sealing performance of the fuel pump assembly may cause fuel leakage and increase the risk of fire in the vehicle.

[0003] In the related art, it is necessary to reproduce the fault of the fuel pump and disassemble it for diagnosis and analysis.

[0017] If the current working current is greater than or equal to the second preset current value, and the fuel pump supply is less than the instantaneous fuel consumption of the engine, and the fuel pump supply is less than the preset fuel supply lower limit, then the fault type is predicted to be a pump core stuck state or a short circuit state, wherein the first preset current value is less than the second preset current value.

[0054] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0055] The following describes a method, device, vehicle and storage medium for predicting a fuel pump fault state according to an embodiment of the present application with reference to the accompanying drawings. First, a method for predicting a fuel pump fault state according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0056] Figure 1 It is a flow chart of a method for predicting a fuel pump fault state according to an embodiment of the present application.

[0057] For example, Figure 1 As shown, the method for predicting the fuel pump fault state includes the following steps:

[0058] In step S101, the current operating current of the fuel pump, the fuel supply of the fuel pump, the current fuel tank liquid level and the instantaneous fuel consumption of the engine are obtained.

[0059] Specifically, in the embodiment of the present application, the vehicle ECU (Electronic Control Unit) can simultaneously monitor parameters such as the current working current of the fuel pump, the fuel supply of the fuel pump, the current fuel tank level and the instantaneous fuel consumption of the engine. Among them, the current working current of the fuel pump can be monitored in real time by a current sensor installed in the fuel pump circuit. This data can reflect the power consumption of the fuel pump during working time, thereby indirectly reflecting its operating status; the fuel supply of the fuel pump can be calculated by a flow sensor or a related algorithm to calculate the fuel supply per unit time of the fuel pump. This data is directly related to the output capacity of the fuel pump and is of great significance for judging whether it has problems such as blockage, wear or efficiency reduction; the current fuel tank level can be obtained in real time by a level sensor, and this data is of great reference value for evaluating the working environment of the fuel pump and predicting potential faults (such as insufficient fuel supply caused by too low oil level); the instantaneous fuel consumption of the engine can be directly obtained by the ECU or other related sensors. By comparing the fuel supply of the fuel pump and the instantaneous fuel consumption of the engine, it can be evaluated whether the actual fuel supply capacity of the fuel pump meets the engine demand. The vehicle ECU can simultaneously obtain data from current sensors, flow sensors or related algorithm calculation results, liquid level sensors, etc., to achieve real-time monitoring of parameters such as the current working current of the fuel pump, the fuel supply of the fuel pump, the current fuel tank level, and the instantaneous fuel consumption of the engine.

[0060] In step S102, the fault type of the fuel pump is predicted according to the current working current, the fuel supply of the fuel pump, the current fuel tank liquid level and the instantaneous fuel consumption of the engine.

[0061] That is to say, by comprehensively analyzing and comparing the data such as the current working current, fuel pump fuel supply, current fuel tank liquid level and instantaneous fuel consumption of the engine obtained in step S101, and comparing with the data range or threshold under the normal state, any data points that are abnormal or deviate from the normal trend can be identified, and based on the results of the data analysis and the preset fault type, the possible or impending fault type of the fuel pump can be judged, among which common fault types of the fuel pump include idling of the fuel pump core, dry burning due to lack of oil, pump core jam (impeller stuck), short circuit (rotor short circuit), oil leakage, etc.

[0062] The following describes in detail how to predict the fault type of the fuel pump based on the current operating current, fuel pump fuel supply, current fuel tank level and engine instantaneous fuel consumption.

[0063] As a possible implementation method, in some embodiments, the fault type of the fuel pump is predicted based on the current working current, the fuel pump fuel supply, the current fuel tank liquid level and the instantaneous fuel consumption of the engine, including: determining whether the current working current is less than a first preset current value, and whether the fuel pump fuel supply is less than the instantaneous fuel consumption of the engine, and whether the current fuel tank liquid level is less than a preset alarm level; if the current working current is less than the first preset current value, and the fuel pump fuel supply is less than the instantaneous fuel consumption of the engine, and the current fuel tank liquid level is less than the preset alarm level, then the predicted fault type is a pump core idling state or a dry burning state.

[0064] The first preset current value may be a value pre-set by researchers in the field, a value obtained through a limited number of experiments, or a value obtained through a limited number of computer simulations, which will not be described in detail here. Preferably, the first preset current value is set to 5A in the embodiment of the present application.

[0065] Specifically, the current working current is compared with the theoretical working current of the fuel pump, that is, it is determined whether the current working current is less than the first preset current value (such as 5A), and the fuel supply of the fuel pump at the current moment is compared with the instantaneous fuel consumption of the engine, that is, it is determined whether the fuel supply of the fuel pump is less than the instantaneous fuel consumption of the engine, and the current fuel tank liquid level is compared with the preset alarm liquid level, that is, it is determined whether the current fuel tank liquid level is less than the preset alarm liquid level. If the above three conditions are met at the same time, that is, the current working current is less than the first preset current value, the fuel pump fuel supply is less than the instantaneous fuel consumption of the engine, and the fuel tank liquid level is less than the preset alarm liquid level. If the fuel pump fails to meet the fuel demand of the engine, which may cause the engine performance to decline or even stall, and the current fuel tank level is lower than the preset alarm level (indicating that the fuel tank is running low on fuel), the fuel pump fault is predicted to be idling or dry-burning. In this case, due to low current and insufficient fuel supply, the fuel tank level is too low, indicating that the fuel pump is running without sufficient fuel lubrication and cooling. This operating environment will cause the fuel pump core to idle or dry-burn, thus causing potential failures.

[0066] Therefore, timely detection and appropriate maintenance measures are very necessary to avoid further damage and potential safety risks.

[0067] As another possible implementation method, in some embodiments, the fault type of the fuel pump is predicted based on the current working current, the fuel pump fuel supply, the current fuel tank liquid level and the instantaneous fuel consumption of the engine, including: judging whether the current working current is greater than or equal to the second preset current value, and whether the fuel pump fuel supply is less than the instantaneous fuel consumption of the engine, and whether the fuel pump fuel supply is less than the preset fuel supply lower limit; if the current working current is greater than or equal to the second preset current value, and the fuel pump fuel supply is less than the instantaneous fuel consumption of the engine, and the fuel pump fuel supply is less than the preset fuel supply lower limit, then the predicted fault type is a pump core stuck state or a short circuit state, wherein the first preset current value is less than the second preset current value.

[0068] The second preset current value may be a value pre-set by researchers in the field, a value obtained through a limited number of experiments, or a value obtained through a limited number of computer simulations, which will not be described in detail here. Preferably, the second preset current value is set to 17A in the embodiment of the present application. The preset lower limit of the fuel supply can be set according to the performance parameters of the fuel pump to ensure that the fuel pump will not be lower than this value under normal working conditions.

[0069] Specifically, the current working current is compared with the rated working current of the fuel pump, that is, it is determined whether the current working current is greater than or equal to the second preset current value (such as 17A), and the fuel pump fuel supply at the current moment is compared with the instantaneous fuel consumption of the engine, that is, it is determined whether the fuel pump fuel supply is less than the instantaneous fuel consumption of the engine, and the fuel pump fuel supply is compared with the preset fuel supply lower limit, that is, it is determined whether the fuel pump fuel supply is less than the preset fuel supply lower limit. If the above three conditions are met at the same time, that is, the current working current is greater than or equal to the second preset current value (indicating that the working current is too high, which may be a precursor to motor overload or short circuit), the fuel pump fuel supply is less than the instantaneous fuel consumption of the engine (meaning that the fuel pump cannot meet the fuel demand of the engine, which may cause the engine performance to decline or even stall), and the fuel pump fuel supply is less than the preset fuel supply lower limit (further indicating that the fuel pump may have a serious fuel shortage problem), then the fuel pump fault type is predicted to be a pump core jam state (impeller stuck) or a short circuit state (rotor short circuit), such as Figure 2 This comprehensive judgment method can help users more accurately identify and prevent possible fuel pump failures, thereby ensuring the normal operation of the engine and the safety performance of the vehicle.

[0070] In step S103, an alarm is issued to the user based on the fault type of the fuel pump.

[0071] That is to say, by setting reasonable alarm triggering conditions, such as when the working current of the fuel pump increases abnormally, the fuel supply decreases significantly, the fuel tank liquid level is too low and the fuel supply is insufficient, the alarm reminder is triggered. Among them, the alarm reminder can be in the form of sound, light signal, instrument display, mobile phone APP notification and other methods to ensure that users can receive fault information in time and take corresponding treatment measures.

[0072] As a possible implementation method, in some embodiments, an alarm is issued to a user based on the fault type of the fuel pump, including: generating corresponding fault handling suggestions based on the fault type of the fuel pump; and issuing an alarm to the user according to the fault handling suggestions.

[0073] Specifically, after predicting the fault type of the fuel pump, corresponding fault handling suggestions can be generated based on the fault type of the fuel pump and an alarm reminder can be issued to the user. That is, if the fault type of the fuel pump is the pump core idling state or dry burning state, the user can be advised to stop the car immediately, check the fuel pump and fuel system, and remind the user to check the fuel tank level and refuel as soon as possible; if the fault type of the fuel pump is the pump core blocking state (impeller stuck) or short circuit state (rotor short circuit), the user can be advised to stop the car immediately and contact professional maintenance personnel for inspection and repair. The fault type and fault handling suggestions can be notified to the user through the indicator light on the vehicle dashboard, sound alarm or vehicle information system (such as touch screen). At the same time, the fault type and fault handling suggestions can also be sent to the user's mobile phone or tablet computer through mobile communication methods (such as text messages, APP push, etc.).

[0074] Furthermore, in some embodiments, after the user is alerted based on the fault handling suggestions, it also includes: obtaining information of at least one service station within a preset range of the current vehicle position; generating a corresponding navigation path based on the information of at least one service station, and sending the navigation path to a preset mobile terminal.

[0075] Specifically, after issuing an alarm to the user, the system can automatically use navigation technology to obtain information about service stations within a preset range of the current vehicle position (including the service station's name, address, contact number, and service range, etc.), and based on the service station information, use applications such as the on-board navigation system to generate a corresponding navigation path so that the user can quickly and accurately reach the service station, and send the generated navigation path to the user's preset mobile terminal (such as a mobile phone, tablet computer, etc.) so that the user can view and follow the navigation to the service station in time.

[0076] Therefore, through timely alarm reminders and fault prediction functions, early warning signals can be issued before the fuel pump fails, leaving users with enough time to repair or replace parts.

[0077] According to the prediction method of the fuel pump fault state proposed in the embodiment of the present application, by obtaining the current working current of the fuel pump, the fuel supply of the fuel pump, the current fuel tank liquid level and the instantaneous fuel consumption of the engine, the fault type of the fuel pump can be predicted based on the current working current, the fuel supply of the fuel pump, the current fuel tank liquid level and the instantaneous fuel consumption of the engine, and then, based on the fault type of the fuel pump, an alarm is given to the user. Therefore, by real-time monitoring of parameters such as the working current of the fuel pump and predicting the fault state of the fuel pump, the problem that traditional vehicles cannot be warned in advance when the fuel pump fails is solved, thereby avoiding vehicle driving interruption or other safety hazards caused by fuel pump failure, and improving the driving safety of the vehicle.

[0078] Next, a fuel pump fault state prediction device according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0079] Figure 3 It is a block diagram of a device for predicting a fuel pump fault state according to an embodiment of the present application.

[0080] like Figure 3 As shown, the fuel pump fault status prediction device 10 includes: an acquisition module 100 , a prediction module 200 and a reminder module 300 .

[0081] The acquisition module 100 is used to acquire the current working current of the fuel pump, the fuel supply of the fuel pump, the current fuel tank level and the instantaneous fuel consumption of the engine;

[0082] The prediction module 200 is used to predict the fault type of the fuel pump according to the current working current, the fuel supply of the fuel pump, the current fuel tank liquid level and the instantaneous fuel consumption of the engine;

[0083] The reminder module 300 is used to give an alarm reminder to the user based on the fault type of the fuel pump.

[0084] Furthermore, in some embodiments, the prediction module 200 is specifically configured to:

[0085] Determine whether the current working current is less than a first preset current value, whether the fuel supply of the fuel pump is less than the instantaneous fuel consumption of the engine, and whether the current fuel tank liquid level is less than a preset alarm liquid level;

[0086] When the current working current is less than the first preset current value, the fuel supply of the fuel pump is less than the instantaneous fuel consumption of the engine, and the current fuel tank liquid level is less than the preset alarm liquid level, the predicted fault type is the pump core idling state or dry burning state.

[0087] Furthermore, in some embodiments, the prediction module 200 is specifically configured to:

[0088] Determine whether the current working current is greater than or equal to a second preset current value, and whether the fuel supply of the fuel pump is less than the instantaneous fuel consumption of the engine, and whether the fuel supply of the fuel pump is less than a preset fuel supply lower limit;

[0089] When the current working current is greater than or equal to the second preset current value, and the fuel pump supply is less than the instantaneous fuel consumption of the engine, and whether the fuel pump supply is less than the preset lower limit of the fuel supply, the predicted fault type is a pump core stuck state or a short circuit state, wherein the first preset current value is less than the second preset current value.

[0090] Furthermore, in some embodiments, the reminder module 300 includes:

[0091] A generating unit, used for generating corresponding fault handling suggestions based on the fault type of the fuel pump;

[0092] The reminder unit is used to issue an alarm reminder to the user according to the fault handling suggestions.

[0093] According to an embodiment of the present application, after the user is given an alarm reminder according to the fault handling suggestion, the reminder unit is further used to:

[0094] Obtain information of at least one service station within a preset range of the current vehicle location;

[0095] Based on the information of at least one service station, a corresponding navigation path is generated, and the navigation path is sent to a preset mobile terminal.

[0096] It should be noted that the above explanation of the embodiment of the method for predicting the fault state of a fuel pump is also applicable to the device for predicting the fault state of a fuel pump in this embodiment, and will not be described in detail here.

[0097] According to the prediction device for the fuel pump fault state proposed in the embodiment of the present application, by obtaining the current working current of the fuel pump, the fuel supply of the fuel pump, the current fuel tank liquid level and the instantaneous fuel consumption of the engine, the fault type of the fuel pump can be predicted based on the current working current, the fuel supply of the fuel pump, the current fuel tank liquid level and the instantaneous fuel consumption of the engine, and then, based on the fault type of the fuel pump, an alarm is given to the user. Thus, by real-time monitoring of parameters such as the working current of the fuel pump and predicting the fault state of the fuel pump, the problem that the traditional vehicle cannot be warned in advance when the fuel pump fails is solved, thereby avoiding vehicle driving interruption or other safety hazards caused by fuel pump failure, and improving the driving safety of the vehicle.
