Description

Technical Field

[0001] The present application relates to the technical field of monitoring the fuel consumption of a vehicle engine, and more specifically, to a method, device, computer-readable storage medium and electronic device for monitoring the fuel consumption of a vehicle engine. Background Art

[0002] During long-term operation of the engine, the piston, piston ring and cylinder liner will wear with mileage. When the piston ring, piston ring groove and cylinder liner are abnormally worn, the engine leakage will increase and the oil consumption will increase. When the oil ring is abnormally worn or has abnormal contact, the oil ring will not scrape the oil smoothly, which will also increase the oil consumption. When excessive oil consumption occurs, it will not only affect the product reliability but also greatly cause customer complaints and affect the product reputation.

[0003] The existing technology determines the fuel consumption of a vehicle based on the vehicle's mileage and fuel consumption. If the fuel consumption is high, general users will think that the sudden increase in fuel consumption is caused by the engine itself, affecting the product reputation. However, in actual operation, fuel consumption is not only related to the performance of the engine, but may also be affected by other factors. Therefore, when the fuel consumption per mileage increases, users are informed that it is caused by non-engine factors to reduce customer complaints.

[0004] Therefore, how to accurately monitor the oil consumption of the engine during market operation is crucial. Accurate monitoring is also of great research significance for studying the oil consumption under different road conditions and mileage distribution in the market.

[0035] In this embodiment, a method for monitoring the fuel consumption of a vehicle engine is provided, which runs on a mobile terminal, a computer terminal or a similar computing device. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0036] Figure 2 1 is a flow chart of a method for monitoring vehicle engine fuel consumption according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0037] Step S201, obtaining the real-time fuel volume and cumulative mileage of the vehicle in two consecutive parking states, and determining the fuel consumption rate according to the real-time fuel volume and cumulative mileage in the two consecutive parking states;

[0038] Specifically, each time the vehicle stops for a preset time, the real-time oil level is determined by the correspondence between the calibrated oil level and the oil capacity, and the fuel consumption rate is determined by the real-time oil level and the accumulated mileage. The preset time can be set according to specific calculation requirements, for example, it can be set to 2 minutes, 5 minutes, 10 minutes, etc.

[0039] Step S202, obtaining the road spectrum data of the vehicle between two adjacent stops, wherein the road spectrum data includes at least one of the driving altitude, ambient temperature, vehicle speed, throttle opening, actual torque, and intake manifold pressure;

[0040] Specifically, during the actual operation of the vehicle, accurate parameters such as "mileage, altitude, ambient temperature, vehicle speed, throttle" are obtained through the vehicle and its driving companion.

[0041] Step S203, determine the fuel consumption result based on the fuel consumption rate and the road spectrum data, and send the fuel consumption result to the user end, wherein the fuel consumption result is the influence trend of any parameter in the road spectrum data on the fuel consumption rate, and the influence trend is determined based on the mapping relationship between any parameter in the pre-set road spectrum data and the fuel consumption rate.

[0042] Specifically, first, a mapping relationship between various parameters and fuel consumption rate is constructed according to the vehicle's operating data, and then the fuel consumption rate corresponding to any parameter is determined according to the mapping relationship and the data size of each parameter in the road spectrum data. In this way, the user can intuitively determine the relationship between the actual fuel consumption rate and the fuel consumption rate determined by the mapping relationship, and can determine which specific factors lead to the increase in the actual fuel consumption rate. This plays an extremely important role in helping users understand the characteristics of the entire vehicle.

[0043] Especially when customers are doing short-distance transshipment or waiting in line for a long time (especially when idling for a long time with air conditioning in winter and summer), the oil consumption level under such conditions will exceed the requirements of the normal oil change cycle. Users can intuitively feel the difference in oil consumption caused by different working conditions through the data display of the oil consumption results, which can improve customers' understanding of the engine oil consumption level. This is not caused by the hardware problem of the engine itself, but is a "unique attribute" under this specific working condition, avoiding the bad "brand effect" due to cognitive bias. Secondly, for operating conditions like mountainous areas, this typical road spectrum condition with frequent starting and stopping, acceleration and deceleration, and low average speed on uphill and downhill roads will also have different differences in oil consumption from normal national highways and expressway roads. This plays an extremely important role in helping users understand the characteristics of the entire vehicle.

[0044] Through this embodiment, the real-time fuel level and cumulative mileage of the vehicle in two adjacent parking states are obtained, and the fuel consumption rate is determined based on the real-time fuel level and cumulative mileage in the two adjacent parking states; the road spectrum data of the vehicle between two adjacent parkings is obtained, wherein the road spectrum data includes at least one of driving altitude, ambient temperature, vehicle speed, throttle opening, actual torque, and intake manifold pressure; the fuel consumption result is determined based on the fuel consumption rate and the road spectrum data, and the fuel consumption result is sent to the user end, wherein the fuel consumption result is the influence trend of any parameter in the road spectrum data on the fuel consumption rate, and the influence trend is determined based on the mapping relationship between any parameter in the road spectrum data and the fuel consumption rate that is preset. By sending the fuel consumption results to the user, the impact of vehicle speed, mileage, ambient temperature and altitude on vehicle fuel consumption can be shown to the user, which can be used to enhance the customer's intuitive feeling of vehicle fuel consumption, and let the user know that the increase in fuel consumption is not only caused by hardware problems of the engine itself, which is very important for users to understand the characteristics of the whole vehicle. By combining road spectrum data with fuel consumption rate, the influence trend of any parameter in the road spectrum data on the fuel consumption rate can be shown to the user, thereby solving the problem that the prior art lacks a technical solution to show users how multiple factors affect vehicle fuel consumption.

[0045] In the specific implementation process, it is determined that the fuel consumption rate of the vehicle is abnormal. Figure 3 As shown, the specific steps include:

[0046] Step S301, judgment step: determining whether the fuel consumption rate is greater than the fuel consumption rate limit;

[0047] Step S302, when the judging step indicates that the fuel consumption rate is greater than the fuel consumption rate limit, the cumulative number is increased by 1;

[0048] Step S303, when the accumulated number of times is greater than or equal to the first preset number of times and less than the second preset number of times, a prompt message is generated, wherein the prompt message is used to prompt that the fuel consumption rate of the vehicle is abnormal.

[0049] Among them, the first preset number of times can be set to 5 times, 10 times, etc., and the second preset number of times can be set to 20 times, 30 times, etc., and the second preset number of times must be greater than the first preset number of times.

[0050] When the method detects that the fuel consumption rate is greater than the fuel consumption rate limit for a number of times and is continuously greater than a first preset number of times, it is necessary to remind the driver that the fuel consumption rate is high. The driver is required to determine whether it is caused by a hardware problem of the engine itself or by environmental factors based on the fuel consumption results of the client. This helps the driver to troubleshoot the high fuel consumption of the vehicle.

[0051] Specifically, when the judgment step indicates that the fuel consumption rate is greater than the fuel consumption rate limit, after the cumulative number is increased by 1, the method also includes: when it is determined that the cumulative number is greater than a second preset number, generating an alarm message, wherein the alarm message is used to prompt that the vehicle has an engine failure, and the engine failure includes at least one of piston wear, piston ring wear, and cylinder liner wear.

[0052] The engine failures that cause increased fuel consumption in this method also include abnormal wear of the air filter, intake and four-matching piston ring group. By setting the second preset number of times, it helps to remind the driver to detect engine failures, thereby improving the safety of the entire vehicle.

[0053] More specifically, after obtaining the real-time fuel level and accumulated mileage of the vehicle during two adjacent stops, the method also includes: determining the driving condition of the vehicle based on the fuel level and mileage of the vehicle each time it stops; obtaining the road spectrum data of the vehicle between two adjacent stops and the fuel consumption rate corresponding to the road spectrum data; generating a fuel consumption result based on the driving condition combined with the road spectrum data and the fuel consumption rate, and sending the fuel consumption result to the user end.

[0054] This method will increase fuel consumption when customers are doing short-distance reverse transportation or long-term waiting in line (especially when idling for a long time with air conditioning in winter and summer), as well as in mountainous areas. This typical road spectrum with frequent starts and stops, acceleration and deceleration, and low average speed on uphill and downhill roads will also increase fuel consumption. In addition, mountainous areas will also have different differences in oil consumption from normal national highways and expressways. This is very important for users to understand the characteristics of the whole vehicle.

[0055] Further, the fuel consumption rate is determined according to the real-time fuel volume and the accumulated mileage in two adjacent parking states, including: according to the first formula: W = (L t-1 -L t ) / (K t -K t-1 ), determine the fuel consumption rate between the t-1st stop and the tth stop of the vehicle, where W is the fuel consumption rate, L is the fuel consumption rate, t is the fuel volume of the vehicle at the tth stop, L t-1 is the fuel volume of the vehicle at the t-1th stop, K t is the mileage of the vehicle’s t-th stop, K t-1 is the mileage of the vehicle's t-1th stop; after determining the amount of oil and the mileage between the vehicle's t-1th stop and the tth stop and determining the fuel consumption rate between the vehicle's t-1th stop and the tth stop, the method further includes: determining whether the fuel consumption rate is greater than a fuel consumption rate limit, and if it is determined that the fuel consumption rate is greater than the fuel consumption rate limit, recording and storing the fuel consumption rate.

[0056] This method stores data with a fuel consumption rate greater than the fuel consumption rate limit, which helps manufacturers provide accurate oil consumption data for subsequent vehicle and engine development, so as to continuously improve and optimize products. At the same time, it can identify high oil consumption risks in the market in advance and improve user experience and vehicle safety.

[0057] Furthermore, road spectrum data of vehicles of the same model and the fuel consumption rate corresponding to the road spectrum data are obtained; a target vehicle whose fuel consumption rate is greater than a fuel consumption rate limit is determined among vehicles of the same model; a fuel consumption analysis is performed on the target vehicle based on the fuel consumption rate of the target vehicle and the road spectrum data corresponding to the fuel consumption rate, to determine whether the fuel consumption of the target vehicle greater than the fuel consumption rate limit is caused by an engine failure of the target vehicle.

[0058] This method stores data on vehicles of the same model whose fuel consumption rates are greater than the fuel consumption rate limit, which helps manufacturers analyze vehicles with high fuel consumption, identify risks in advance, avoid large-scale market problems, and provide accurate oil consumption data for subsequent development of complete vehicles and engines, so as to continuously improve and optimize products. At the same time, it can identify high oil consumption risks in the market in advance, enhance user experience and vehicle safety.

[0059] Specifically, before obtaining the real-time fuel level and accumulated mileage of the vehicle in two consecutive parking states, the real-time fuel level of the vehicle is determined as follows: Figure 4 As shown:

[0060] Step S401, statically calibrating the oil level of the engine oil pan of the vehicle to determine a mapping relationship between the fuel level and the oil level;

[0061] Step S402, determining the real-time fuel volume of the vehicle each time it stops according to the fuel level and the mapping relationship.

[0062] This method obtains the relationship of "fuel level-oil amount" by statically calibrating the oil amount in the engine oil pan (different engine oil levels "H1, H2, H3...Hi" correspond to different oil storage amounts "L1, L2, L3...Li").

[0063] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for monitoring the fuel consumption of a vehicle engine of the present application will be described in detail below in combination with specific embodiments.

[0064] During long-term operation of the engine, the piston, piston ring and cylinder liner will wear with mileage. When the piston ring, piston ring groove and cylinder liner are abnormally worn, the engine leakage will increase and the oil consumption will increase. When the oil ring is abnormally worn or has abnormal contact, the oil ring will not scrape the oil smoothly, which will also increase the oil consumption. When excessive oil consumption occurs, it will not only affect the product reliability but also greatly cause customer complaints and affect the product reputation. Therefore, it is very important to accurately monitor the oil consumption of the engine during market operation. Accurate monitoring is also of great research significance for studying the oil consumption under different road conditions and mileage distribution in the market.

[0065] This embodiment involves a specific method for monitoring the fuel consumption of a vehicle engine. The corresponding relationship between the "oil level and oil volume" of the oil pan is obtained through static calibration of the oil pan. During the actual operation of the vehicle, the driving companion obtains the key parameters of the engine by obtaining the parameters of the vehicle such as "mileage, altitude, ambient temperature", and establishes a series of models such as "fuel consumption-road spectrum model" and "fuel consumption-mileage model" to provide guarantees for product development and accurate calculation of vehicle fuel consumption. Figure 5 As shown, including the following:

[0066] By statically calibrating the oil level in the engine oil pan, the relationship between "oil level-oil volume" is obtained (different oil levels "H1, H2, H3...Hi" correspond to different oil storage volumes "L1, L2, L3...Li"). During the actual operation of the vehicle, the precise parameters of the vehicle and its driving companions such as "mileage, altitude, ambient temperature, vehicle speed, and throttle" are used. For example, the oil consumption is accurately predicted by establishing an "oil consumption-mileage model": when the transportation route of the tractor is fixed, the oil consumption is relatively regular on the fixed route. The oil level after the vehicle stops for T1 time is used as the oil volume calculation parameter, and the "oil consumption-mileage model" is established together with the mileage on the dashboard. Mileage model", (this model is based on the factory oil consumption rate limit A. After each stop for T1 time, the oil consumption at the current mileage is calculated through the correspondence between the calibrated oil level and the oil capacity Li. The oil consumption rate is calculated by the remaining oil. The oil consumption rate will be recorded in the "Oil Consumption-Mileage Model" as valid data on oil consumption. When the oil consumption exceeds the limit, the data will be temporarily stored. When it exceeds N2 times in a row, it will be recorded in the database as valid data on high oil consumption at the mileage. The total data points can be used to count the failure rate of "high oil consumption" and the corresponding mileage distribution can be viewed at the same time).

[0067] When the oil consumption per M kilometers after K mileage is counted in the background, it is necessary to pay attention to the vehicle's operating status (i.e., the oil consumption rate W = (L i-1 -L i) / K, when the consumption rate W < the oil consumption limit A, no warning is required; when the oil consumption exceeds the limit A for N1 consecutive times, the yellow warning light for high oil consumption is triggered. If the oil consumption exceeds the limit A for more than N2 consecutive times, the user is reminded to pay attention to the oil consumption). Before exceeding the oil consumption standard, risks are identified in advance to avoid large-scale market problems; secondly, by obtaining key information such as engine speed, vehicle speed, and throttle, an "oil consumption-road spectrum model" is established. The driving companion can summarize the oil consumption under different road spectra through big data, and accurately analyze the impact of different road conditions, vehicle speeds and other factors in the segmented market;

[0068] This effect can be displayed through the whole vehicle and user client to show customers the average speed, average mileage fuel consumption and the impact of altitude on oil consumption. It can be used to enhance customers' intuitive feeling of oil consumption, especially when customers are doing short-distance transshipment or waiting in line for a long time (especially when idling for a long time with air conditioning in winter and summer). The oil consumption level under such conditions will exceed the requirements of the normal oil change cycle. Users can intuitively feel the difference in oil consumption caused by the difference in working conditions through the data display, which can enhance customers' understanding of the engine oil consumption level. This is not caused by the hardware problem of the engine itself, but is a "unique attribute" under this specific working condition, avoiding the bad "brand effect" caused by cognitive bias. Secondly, for mountainous operating conditions, this typical road spectrum condition with frequent starting and stopping, acceleration and deceleration, and low average speed on uphill and downhill will also have different differences in oil consumption from normal national highways and highways. This is very important for users to understand the characteristics of the whole vehicle.

[0069] Among them, the oil consumption-mileage model can be used by the background and users to identify oil consumption risks. When the oil consumption rate rises slowly and is about to approach the critical value, the background will issue an early warning and pay attention to whether the air filter, intake, and four-matching piston ring set have abnormal wear. The oil consumption-road spectrum model can count the road conditions of the whole vehicle, the oil consumption at different altitudes, and the oil consumption corresponding to different intake negative pressure ratios under different road conditions. Based on similar statistics, it is also possible to compare the oil consumption rates corresponding to different vehicle speeds under national highways and mountainous road conditions. The method of this embodiment can be used to accurately calculate and count oil consumption, and continuously improve product reliability.

[0070] In this embodiment, the "oil level-oil quantity" relationship is obtained by calibrating the oil pan, and other key parameters such as "mileage, vehicle speed, throttle" established by the model are obtained through the whole vehicle and the driving companion. The model and parameter acquisition are relatively convenient and feasible, providing accurate oil consumption data for the subsequent development of the whole vehicle and the engine, so as to continuously improve and optimize the product. At the same time, it can identify the high risk of oil consumption in the market in advance, and improve the user experience and vehicle safety.

[0071] The embodiment of the present application also provides a device for monitoring the fuel consumption of a whole vehicle engine. It should be noted that the device for monitoring the fuel consumption of a whole vehicle engine in the embodiment of the present application can be used to execute the method for monitoring the fuel consumption of a whole vehicle engine provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0072] The following is an introduction to the device for monitoring the fuel consumption of a vehicle engine provided in an embodiment of the present application.

[0073] Figure 6 Schematic diagram of a device for monitoring vehicle engine fuel consumption according to an embodiment of the present application. Figure 6 As shown, the device comprises:

[0074] The first acquisition unit 61 is used to acquire the real-time fuel quantity and cumulative mileage of the vehicle in two consecutive parking states, and determine the fuel consumption rate according to the real-time fuel quantity and cumulative mileage in the two consecutive parking states;

[0075] Specifically, each time the vehicle stops for a preset time, the real-time oil level is determined by the correspondence between the calibrated oil level and the oil capacity, and the fuel consumption rate is determined by the real-time oil level and the accumulated mileage. The preset time can be set according to specific calculation requirements, for example, it can be set to 2 minutes, 5 minutes, 10 minutes, etc.

[0076] The second acquisition unit 62 is used to acquire the road spectrum data of the vehicle between two adjacent stops, wherein the road spectrum data includes at least one of the driving altitude, the ambient temperature, the vehicle speed, the throttle opening, the actual torque, and the intake manifold pressure;

[0077] Specifically, during the actual operation of the vehicle, accurate parameters such as "mileage, altitude, ambient temperature, vehicle speed, throttle" are obtained through the vehicle and its driving companion.

[0078] The sending unit 63 is used to determine the fuel consumption result based on the fuel consumption rate and the road spectrum data, and send the fuel consumption result to the user end, wherein the fuel consumption result is the influence trend of any parameter in the road spectrum data on the fuel consumption rate, and the influence trend is determined based on the mapping relationship between any parameter in the road spectrum data and the fuel consumption rate set in advance.

[0079] Specifically, first, a mapping relationship between various parameters and fuel consumption rate is constructed according to the vehicle's operating data, and then the fuel consumption rate corresponding to any parameter is determined according to the mapping relationship and the data size of each parameter in the road spectrum data. In this way, the user can intuitively determine the relationship between the actual fuel consumption rate and the fuel consumption rate determined by the mapping relationship, and can determine which specific factors lead to the increase in the actual fuel consumption rate. This plays an extremely important role in helping users understand the characteristics of the entire vehicle.

[0080] In this embodiment, the first acquisition unit is used to obtain the real-time fuel level and cumulative mileage of the vehicle in two adjacent parking states, and determine the fuel consumption rate based on the real-time fuel level and cumulative mileage in the two adjacent parking states; the second acquisition unit is used to obtain the road spectrum data of the vehicle between two adjacent parkings, wherein the road spectrum data includes at least one of driving altitude, ambient temperature, vehicle speed, throttle opening, actual torque, and intake manifold pressure; the sending unit is used to determine the fuel consumption result based on the fuel consumption rate and the road spectrum data, and send the fuel consumption result to the user end, wherein the fuel consumption result is the influence trend of any parameter in the road spectrum data on the fuel consumption rate, and the influence trend is determined based on the mapping relationship between any parameter in the road spectrum data and the fuel consumption rate set in advance. By sending the fuel consumption results to the user, the impact of vehicle speed, mileage, ambient temperature and altitude on vehicle fuel consumption can be shown to the user, which can be used to enhance the customer's intuitive feeling of vehicle fuel consumption, and let the user know that the increase in fuel consumption is not only caused by hardware problems of the engine itself, which is very important for users to understand the characteristics of the whole vehicle. By combining road spectrum data with fuel consumption rate, the influence trend of any parameter in the road spectrum data on the fuel consumption rate can be shown to the user, thereby solving the problem that the prior art lacks a technical solution to show users how multiple factors affect vehicle fuel consumption.

[0081] As an optional solution, the device also includes a judgment unit, an indication unit and a first generating unit, the judgment unit is used to execute a judgment step: determine whether the fuel consumption rate is greater than the fuel consumption rate limit; the indication unit is used to add 1 to the cumulative number of times when the judgment step indicates that the fuel consumption rate is greater than the fuel consumption rate limit; the first generating unit is used to generate a prompt message when the cumulative number of times is greater than or equal to a first preset number of times and less than a second preset number, wherein the prompt message is used to prompt that the fuel consumption rate of the vehicle is abnormal.

[0082] Specifically, when it is detected that the fuel consumption rate is greater than the fuel consumption rate limit for a number of times and is continuously greater than the first preset number of times, the driver needs to be reminded that the fuel consumption rate is high. The driver needs to combine the fuel consumption results of the client to determine whether it is caused by a hardware problem of the engine itself or by environmental factors. This helps the driver to troubleshoot the high fuel consumption of the vehicle.

[0083] In an optional scheme, the device also includes a second generating unit, which is used to generate an alarm message when the judgment step indicates that the fuel consumption rate is greater than the fuel consumption rate limit, after the cumulative number is increased by 1, and when it is determined that the cumulative number is greater than a second preset number, wherein the alarm message is used to prompt that the vehicle has an engine failure, and the engine failure includes at least one of piston wear, piston ring wear, and cylinder liner wear.

[0084] Specifically, engine failures that lead to increased fuel consumption also include abnormal wear of the air filter, intake, and four-matching piston ring group. By setting the second preset number of times, it helps to remind the driver to detect engine failures, thereby improving the safety of the entire vehicle.

[0085] An optional solution, the device also includes a first determination unit, a third acquisition unit and a third generation unit; the first determination unit is used to determine the vehicle's driving condition based on the vehicle's fuel volume and mileage each time it stops after acquiring the vehicle's real-time fuel volume and accumulated mileage in two adjacent parking states; the third acquisition unit is used to acquire the vehicle's road spectrum data between two adjacent parkings and the fuel consumption rate corresponding to the road spectrum data; the third generation unit is used to generate a fuel consumption result based on the driving condition combined with the road spectrum data and the fuel consumption rate, and send the fuel consumption result to the user end.

[0086] Specifically, when customers are doing short-distance reverse transport or waiting in line for a long time (especially when idling for a long time with air conditioning in winter and summer), as well as in mountainous areas, such typical road conditions of frequent starting and stopping, acceleration and deceleration, and low average speed on uphill and downhill roads will increase fuel consumption. In addition, there will be different differences in oil consumption between mountainous areas and normal national highways and expressways. This is very important for users to understand the characteristics of the whole vehicle.

[0087] In an optional solution, the first acquisition unit includes a determination module and a storage module, and the determination module is used to determine the first formula: W = (L t-1 -L t ) / (K t -K t-1 ), determine the fuel consumption rate between the t-1st stop and the tth stop of the vehicle, where W is the fuel consumption rate, L is the fuel consumption rate, t is the fuel volume of the vehicle at the tth stop, L t-1 is the fuel volume of the vehicle at the t-1th stop, K t is the mileage of the vehicle’s tth stop, K t-1is the mileage of the vehicle's t-1th stop; the storage module is used to determine whether the fuel consumption rate is greater than the fuel consumption rate limit after determining the amount of oil and the mileage between the vehicle's t-1th stop and the tth stop and determining the fuel consumption rate between the vehicle's t-1th stop and the tth stop, and if it is determined that the fuel consumption rate is greater than the fuel consumption rate limit, record and store the fuel consumption rate.

[0088] Specifically, storing data with a fuel consumption rate greater than the fuel consumption rate limit will help manufacturers provide accurate oil consumption data for subsequent vehicle and engine development, so as to continuously improve and optimize products. At the same time, it can identify high oil consumption risks in the market in advance and enhance user experience and vehicle safety.

[0089] An optional solution, the device also includes a fourth acquisition unit, a second determination unit and an analysis unit; the fourth acquisition unit is used to obtain road spectrum data of vehicles of the same model and the fuel consumption rate corresponding to the road spectrum data; the second determination unit is used to determine the target vehicle whose fuel consumption rate is greater than the fuel consumption rate limit among vehicles of the same model; the analysis unit is used to perform fuel consumption analysis on the target vehicle according to the fuel consumption rate of the target vehicle and the road spectrum data corresponding to the fuel consumption rate, and determine whether the fuel consumption of the target vehicle greater than the fuel consumption rate limit is caused by an engine failure of the target vehicle.

[0090] Specifically, by storing data on vehicles of the same model whose fuel consumption rates are greater than the fuel consumption rate limit, it helps manufacturers analyze vehicles with high fuel consumption, identify risks in advance, avoid large-scale market problems, and provide accurate engine oil consumption data for subsequent development of complete vehicles and engines, so as to continuously improve and optimize products. At the same time, it can identify high market engine oil consumption risks in advance, enhance user experience and vehicle safety.

[0091] An optional solution, the device also includes a calibration unit and a third determination unit; the calibration unit is used to statically calibrate the oil level in the vehicle's engine oil pan before obtaining the real-time oil level and accumulated mileage of the vehicle in two adjacent parking states, and determine the mapping relationship between the fuel level and the oil level; the third determination unit is used to determine the real-time oil level of the vehicle each time it stops based on the fuel level and the mapping relationship.

[0092] Specifically, by statically calibrating the oil level in the engine oil pan, the relationship of "fuel level-oil level" is obtained (different engine oil levels "H1, H2, H3...Hi" correspond to different oil storage capacities "L1, L2, L3...Li").

[0093] The device for monitoring vehicle engine fuel consumption includes a processor and a memory. The first acquisition unit, the second acquisition unit and the sending unit are stored in the memory as program units, and the processor executes the program units stored in the memory to implement corresponding functions. The modules are all located in the same processor; or, the modules are located in different processors in any combination.

[0094] The processor includes a kernel, and the kernel retrieves the corresponding program unit from the memory. One or more kernels can be set, and the problem that the prior art lacks a technical solution for displaying multiple factors affecting vehicle fuel consumption to users is solved by adjusting kernel parameters.

[0095] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.
