[0054] Due to the fluctuation of oil prices and the enhancement of environmental protection awareness in the prior art, improving fuel efficiency and reducing energy consumption have become the focus of attention of the automobile industry and vehicle owners. Accurate estimation of the remaining fuel quantity can help drivers optimize driving behavior and choose more economical driving strategies, such as avoiding sudden acceleration and sudden braking, and reasonably planning the route to reduce unnecessary travel, thereby achieving the goal of energy saving and emission reduction and reducing operating costs.

[0055] With the development of technologies such as Internet of Vehicles, big data, and artificial intelligence, the intelligent management level of vehicles has been greatly improved. Accurate fuel quantity management is an important part of the intelligent vehicle management system, which can be integrated with other systems (such as navigation, remote diagnosis, maintenance reminders, etc.) to provide whole-cycle health management and services for vehicles.

[0056] In daily driving, uncertain fuel quantity estimation often causes anxiety to drivers, especially on long trips or unfamiliar routes. An accurate fuel quantity estimation system can reduce this uncertainty, improve the driving experience, and avoid inconvenience or danger caused by running out of fuel.

[0057] The present application provides a solution that obtains the vehicle state and the current fuel quantity in real time, and obtains a more accurate fuel tank fuel quantity estimation value by combining the fuel quantity correlation factor, to provide a more accurate estimated fuel quantity for the user. The accuracy of the estimated fuel quantity can help the driver adjust the driving strategy and plan the route containing the gas station, thereby reducing unnecessary fuel consumption and saving costs. The present application avoids the inaccurate display of the fuel tank fuel quantity during vehicle operation, which leads to unreasonable route planning.

[0058] From the above embodiment, the application discloses a vehicle oil estimation method, device, equipment and storage medium, relates to the technical field of vehicles, and discloses the following: obtaining a current vehicle state and a current oil correlation factor state of a target vehicle; obtaining a vehicle oil related parameter of the target vehicle based on the current vehicle state; querying an oil calibration table according to the vehicle oil related parameter to obtain an initial oil quantity; and adjusting the initial oil quantity according to the current oil correlation factor state and a preset oil factor corresponding table to obtain an estimated oil quantity.

[0059] It should be noted that the execution subject of the embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone or the like, or an electronic device, a vehicle oil estimation device or the like capable of realizing the above functions. The embodiment and the following embodiments will be described below by taking the vehicle oil estimation device as an example.

[0060] Based on this, the embodiment of the application provides a vehicle oil estimation method, which refers to Figure 1 , Figure 1 The flowchart of the first embodiment of the vehicle oil estimation method of the application is shown in FIG. 1.

[0061] In the embodiment, the vehicle oil estimation method comprises steps S10-S40.

[0062] Step S10: obtaining a current vehicle state and a current oil correlation factor state of a target vehicle.

[0063] It can be understood that the current vehicle state can include a refueling state, an acceleration / deceleration driving state, an uphill / downhill state and a steering state.

[0064] It should be noted that the current oil correlation factor state can be a current oil temperature T, a slope P, a vehicle speed v, a liquid level height h and a liquid level pressure S of the target vehicle.

[0065] It can be understood that the current oil correlation factor state can be obtained according to data collection by various sensors provided in the vehicle.

[0066] It should be understood that the vehicle refueling state can also be obtained according to the signal of the vehicle related sensor, for example, whether it is in the refueling state, which can be determined according to the on-off signal of the vehicle tank, the vehicle acceleration / deceleration state can be determined according to the change of the vehicle speed at the front and rear time, for example, the steering state can be determined by the enable signal of the steering signal, etc.

[0067] In step S20, the vehicle oil amount related parameter of the target vehicle is obtained based on the current vehicle state.

[0068] It can be understood that the vehicle oil amount parameters obtained by different vehicle states can be the same or different.

[0069] It should be noted that the vehicle oil amount related parameter can include oil temperature T, slope P, vehicle speed v, liquid level height h1, liquid level height h2, liquid level height h3, and liquid level pressure S.

[0070] It should be understood that the liquid level height h1, the liquid level height h2, and the liquid level height h3 can be the liquid level heights detected by the liquid level meters at different positions in the tank.

[0071] In a possible implementation, step S20 can include steps A21-A22:

[0072] In step A21, when the current vehicle state is the vehicle refueling state, the vehicle oil amount related parameter is obtained, and the vehicle oil amount related parameter includes fuel temperature, vehicle slope, vehicle speed, tank liquid level pressure, and tank liquid level height.

[0073] In a specific implementation, when the vehicle is refueling: after the vehicle is refueled, the fuel temperature T1 is read by the temperature sensor T, the vehicle parking slope P1 is read by the slope sensor P, the actual vehicle speed v1 is read by the vehicle speed sensor v, the liquid level pressure S1 is read by the liquid level pressure sensor S arranged in the tank, the liquid level heights H1, H2, and H3 are respectively read by the liquid level height sensors h1, h2, and h3, the average value aveH1 of the liquid level heights H1, H2, and H3 is taken, and the actual oil amount o1 is read on the instrument display according to the oil amount model calibrated in the early stage.

[0074] In step A22, when the current vehicle state is any one of the vehicle acceleration / deceleration state, the uphill / downhill state, and the steering state, the vehicle oil amount related parameter is obtained, and the vehicle oil amount related parameter includes fuel temperature, vehicle slope, first vehicle speed, second vehicle speed, tank liquid level pressure, and tank liquid level height.

[0075] In a specific implementation, when the vehicle is accelerating or decelerating, the fuel temperature T1 is read by the temperature sensor T, the vehicle parking slope P2 is read by the slope sensor P, the actual vehicle speed v2 and v3 (i.e., the first vehicle speed and the second vehicle speed) are read by the vehicle speed sensor v, and the acceleration a1 is converted by a model, the speed difference between v2 and v3 and the speed change time can be used to obtain the acceleration value, the liquid level pressure S2 is read by the liquid level pressure sensor S arranged in the fuel tank, the average liquid level aveH2 (the average of the liquid levels H4, H5, and H6) is obtained by reading the liquid levels H4, H5, and H6, and the actual fuel quantity o2 is read on the instrument display according to the fuel quantity model calibrated in the early stage.

[0076] When the vehicle is driving uphill or downhill, the fuel temperature T1 is read by the temperature sensor T, the vehicle parking slope P3 is read by the slope sensor P, the actual vehicle speed v4 and v5 are read by the vehicle speed sensor v, and the acceleration a2 is converted by a model, the liquid level pressure S3 is read by the liquid level pressure sensor S arranged in the fuel tank, the average liquid level aveH3 (the average of the liquid levels H7, H8, and H9) is obtained by reading the liquid levels H7, H8, and H9, and the actual fuel quantity o3 is read on the instrument display according to the fuel quantity model calibrated in the early stage.

[0077] When the vehicle is driving left or right, the fuel temperature T1 is read by the temperature sensor T, the vehicle parking slope P4 is read by the slope sensor P, the actual vehicle speed v6 and v7 are read by the vehicle speed sensor v, and the acceleration a3 is converted by a model, the liquid level pressure S4 is read by the liquid level pressure sensor S arranged in the fuel tank, the average liquid level aveH4 (the average of the liquid levels H10, H11, and H12) is obtained by reading the liquid levels H10, H11, and H12, and the actual fuel quantity o4 is read on the instrument display according to the fuel quantity model calibrated in the early stage.

[0078] In this embodiment, by monitoring the fuel temperature, the vehicle slope, the vehicle speed, and other parameters in real time, the current fuel consumption can be more accurately estimated, and by comprehensively analyzing the vehicle state and the fuel quantity related parameters, the vehicle information system can provide more accurate fuel remaining mileage estimation for the driver, reduce the user's range anxiety, and improve the driving experience.

[0079] The above is only an implementation manner of step S20 provided by the embodiment, and the embodiment does not specifically limit the specific implementation manner of step S20.

[0080] In step S30, the initial fuel quantity is obtained by querying the fuel quantity calibration table according to the vehicle fuel quantity related parameters, and the fuel quantity calibration table includes one-to-one corresponding vehicle fuel quantity related parameters and gear fuel quantities.

[0081] It can be understood that,

[0082] In a possible implementation, before step S30, steps A301-A303 can be included:

[0083] Step A301, obtaining a vehicle fuel quantity related parameter of a target vehicle.

[0084] It should be noted that the target vehicle can be a vehicle currently performing fuel quantity estimation.

[0085] Step A302, obtaining an initial gear fuel quantity based on the vehicle fuel quantity related parameter.

[0086] It can be understood that the initial gear fuel quantity can be understood as a tank fuel quantity obtained after calculation based on the vehicle fuel quantity related parameter.

[0087] It should be noted that the specific calculation method can be

[0088] If the liquid level height h (such as one of h1, h2, and h3 as the current liquid level) is known, and the geometric shape of the tank or oil tank is known, the oil volume in the tank can be determined by geometric calculation or by consulting a pre-established liquid level-volume calibration curve. For complex container shapes, three-dimensional modeling or piecewise linearization processing can be required. If there are multiple liquid level heights, the time series change represented by these data points can need to be considered to calculate the instantaneous or average fuel quantity. The volume of the oil will expand or shrink with temperature changes. Usually, there is a temperature compensation coefficient or chart to adjust the calculated volume according to the current oil temperature T. This involves the oil expansion coefficient, and the liquid level pressure S (especially in closed or pressure vessels) can affect the liquid level reading. The pressure needs to be converted into a change in equivalent height, and then this value is subtracted or added from the original liquid level height to obtain the true liquid level height, and there are other calculation methods, which are not limited in the embodiment, and the calculation method can be selected according to the actual situation.

[0089] It should be emphasized that the initial gear fuel quantity does not take into account the driving state of the vehicle, and different driving states have a certain influence on the vehicle fuel quantity related parameter, resulting in that the initial gear fuel quantity is not necessarily accurate.

[0090] In a specific implementation, the initial gear fuel quantity corresponding to the vehicle fuel quantity related parameter A is a, but because of the influence of the vehicle state, the real vehicle fuel quantity related parameter is B, and the initial gear fuel quantity corresponding to B is not a, so there is an error between the initial gear fuel quantity and the real fuel quantity.

[0091] Step A303, obtaining a fuel quantity calibration table according to the vehicle fuel quantity related parameter and the initial gear fuel quantity.

[0092] It can be understood that the oil calibration table includes one-to-one correspondence between the vehicle oil related parameters and the gear oil.

[0093] It should be noted that the gear oil corresponding to the vehicle oil related parameters in the oil calibration table can be the ideal oil amount when the vehicle is in a stable normal condition.

[0094] It should be noted that the oil calibration table can be the relationship between the calibrated oil sensor gear oil o and the following parameters, i.e., the relationship between the oil temperature T, the slope P, the vehicle speed v, the liquid level height h1, the liquid level height h2, the liquid level height h3, and the liquid level pressure S.

[0095] In this embodiment, by establishing an oil calibration table based on vehicle oil related parameters, not only the fuel efficiency and driving experience of the vehicle can be improved, but also the generation of the oil calibration table takes into account the specific conditions and driving environment of the vehicle, and can provide personalized oil management strategies for each vehicle. It can better adapt to the needs of the vehicle in different use scenarios, whether it is urban congestion, high-speed cruising or rugged mountain roads, it can provide suitable fuel consumption expectations to help the owner or fleet manager optimize the oil strategy.

[0096] The above is only an implementation manner of step S20 provided by the present embodiment, and the present embodiment does not specifically limit the specific implementation manner of step S20.

[0097] Step S40, adjusting the initial oil amount according to the current oil amount correlation factor state and the preset oil amount factor corresponding table to obtain the estimated oil amount.

[0098] It can be understood that the current oil amount correlation factor state will change under different vehicle driving conditions, and the influence of the change degree and change size of the current oil amount correlation factor state on the initial oil amount will also be different.

[0099] It should be understood that the preset oil amount factor corresponding table includes the corresponding oil amount change degree under different change degrees of each oil amount correlation factor. For example, if the temperature changes by 5 degrees, the corresponding oil amount change degree is 30, and if the temperature changes by 10 degrees, the corresponding oil amount change degree is 40. It does not represent the relationship between the actual temperature change degree and the oil amount change degree.

[0100] It should be noted that the reference oil amount correlation factor state for obtaining the oil amount change degree in the preset oil amount factor corresponding table is the change reference value; based on the change reference value and the current oil amount correlation factor state, the change degree of the current oil amount correlation factor can be obtained, the oil amount correction parameter is obtained based on the change degree and the preset oil amount factor corresponding table, and the initial oil amount is adjusted according to the oil amount correction parameter to obtain the estimated oil amount.

[0101] In specific implementation, the implementation logic of the vehicle oil estimation method can refer toFigure 2 , Figure 2 The figure is a schematic diagram of a brief flow of the vehicle oil amount estimation method, in which the calibrated oil tank oil amount is related to temperature, vehicle speed, slope, oil tank liquid level height, and oil tank liquid level pressure. According to the operating conditions of the vehicle, the temperature, vehicle speed, slope, oil tank liquid level height, and oil tank liquid level pressure are collected in real time through the CAN line. The oil tank oil amount is calculated in real time through the pre-calibration program of the oil tank controller, and the actual oil amount is displayed on the instrument panel.

[0102] The embodiment provides a vehicle oil amount estimation method. By acquiring the vehicle state and the current oil amount in real time, a more accurate oil tank oil amount estimation value is obtained by combining the oil amount correlation factor, so that a more accurate estimated oil amount is provided for a user. The accuracy of the estimated oil amount can help the driver to adjust the driving strategy and plan a route containing a gas station, thereby reducing unnecessary fuel consumption and saving costs. The current inaccurate display of the oil tank oil amount during the operation of the vehicle leads to unreasonable route planning.

[0103] Based on the first embodiment of the application, in the second embodiment of the application, the same or similar contents as the above embodiment one can be referred to the above description, and will not be described in detail. On this basis, please refer to Figure 3 , step S40, the vehicle oil amount estimation method further includes steps S41-S42:

[0104] Step S41, according to the current oil amount correlation factor, the reference oil amount conversion amount is obtained by querying the preset oil amount factor corresponding table. The preset oil amount factor corresponding table includes one-to-one oil amount correlation factor and oil amount conversion amount.

[0105] In a possible implementation, step S40 can include steps A401-A402 before step S40:

[0106] Step A401, the oil amount correlation factor is obtained.

[0107] It should be noted that the oil amount correlation factor includes fuel temperature T, vehicle speed v, vehicle slope P, oil tank liquid level height h, and oil tank liquid level pressure S.

[0108] Step A402, based on the vehicle oil amount related parameters in the oil amount calibration table and the oil amount correlation factor, the oil amount change test is performed to obtain the preset factor oil amount corresponding table.

[0109] It can be understood that the vehicle oil amount related parameters in the oil amount calibration table are used as vehicle simulation driving parameters. Based on the simulation driving parameters, one of the oil amount correlation factors is changed, and the other factors remain unchanged.

[0110] It should be noted that the factor is changed by one unit each time, for example, the vehicle speed in the oil quantity correlation factor is changed, the vehicle speed is changed by 10km / h, and the oil quantity change after each change is calculated.

[0111] It can be understood that the preset factor oil quantity corresponding table includes the oil quantity change value corresponding to the change of one unit, two units, and three units of each oil quantity correlation factor from the reference value.

[0112] It should be noted that each oil quantity correlation factor has a reference value, which is dynamically changed based on the reference value. The reference value can be the value of the factor during normal driving.

[0113] It can be understood that each factor has a corresponding preset factor oil quantity corresponding table.

[0114] It should be noted that the oil quantity change test based on the vehicle oil quantity related parameters in the oil quantity calibration table and the oil quantity correlation factor obtains a preset factor oil quantity corresponding table, including: dynamically changing the oil quantity correlation factor to obtain a pre-change oil quantity correlation factor and a post-change oil quantity correlation factor; obtaining the gear oil quantity before and after dynamic change based on the vehicle oil quantity related parameters in the oil quantity calibration table, the pre-change oil quantity correlation factor and the post-change oil quantity correlation factor; and obtaining the preset factor oil quantity corresponding table of the oil quantity correlation factor and the gear oil quantity according to the gear oil quantity before and after dynamic change.

[0115] It can be understood that dynamically changing the oil quantity correlation factor to obtain a pre-change oil quantity correlation factor and a post-change oil quantity correlation factor can be analogized as: having oil quantity correlation factors 1, 2, 3, 4, 5, 6, 7, 8, and changing the seventh factor to a to obtain the post-change oil quantity correlation factors 1, 2, 3, 4, 5, 6, a, 8.

[0116] It can be understood that the vehicle oil quantity related parameter is a related parameter for calculating the oil quantity, and the initial oil quantity is obtained based on the parameter. The oil quantity correction parameter can be obtained according to the change factor; only one of the oil quantity correlation factors is changed, the oil quantity change before and after the change is calculated, the influence of the factor on the oil quantity change is obtained, and the preset factor oil quantity corresponding table of the factor is obtained.

[0117] According to the gear oil quantity before and after dynamic change, the preset factor oil quantity corresponding table of the oil quantity correlation factor and the gear oil quantity is obtained, including: obtaining the dynamic change unit of the oil quantity correlation factor; obtaining the correlation coefficient of the oil quantity correlation factor and the oil quantity change amount according to the dynamic change unit and the gear oil quantity before and after the change; and obtaining the preset factor oil quantity corresponding table of the oil quantity correlation factor and the gear oil quantity according to the correlation coefficient.

[0118] Wherein, it can be understood that the dynamic conversion unit can be the conversion unit of each oil quantity associated factor.

[0119] In a specific implementation, when the fuel temperature T changes, the fuel density p at the current temperature is obtained according to the fuel temperature T and the fuel density corresponding table, and the corresponding table of the oil quantity o of each gear of the oil quantity sensor and the fuel density p is corrected in real time according to the relationship between the fuel density p and the fuel volume V.

[0120] When the vehicle speed v changes, the acceleration a is converted through the model, and the corresponding table of the oil quantity o of each gear of the oil quantity sensor and the vehicle speed v is corrected in real time according to the relationship between the vehicle speed v and the fuel volume V.

[0121] When the vehicle slope P changes, the corresponding table of the oil quantity o of each gear of the oil quantity sensor and the vehicle slope P is corrected in real time according to the relationship between the vehicle slope P and the fuel volume V.

[0122] When the tank liquid level height h changes, the corresponding table of the oil quantity o of each gear of the oil quantity sensor and the tank liquid level height h is corrected in real time according to the relationship between the tank liquid level height h and the fuel volume V.

[0123] When the tank liquid level pressure S changes, the corresponding table of the oil quantity o of each gear of the oil quantity sensor and the tank liquid level pressure S is corrected in real time according to the relationship between the tank liquid level pressure S and the fuel volume V.

[0124] In the embodiment, the preset factor oil quantity corresponding table provides a quantitative basis for the change of the oil quantity under different working conditions, so that the system can more accurately predict the fuel consumption according to the specific conditions of the current vehicle (such as the driving mode, the road slope, the environment temperature, etc.), which helps the driver or the management system to make more efficient energy distribution and driving strategy adjustment.

[0125] The above is only an implementation manner of step S10 provided by the embodiment, and the embodiment does not specifically limit the specific implementation manner of step S10.

[0126] Step S42, adjusting the initial oil quantity according to the reference oil quantity conversion amount to obtain the estimated oil quantity.

[0127] It can be understood that the reference oil quantity conversion amount can be obtained by adding the oil quantity conversion amounts corresponding to each oil quantity associated factor, or can be obtained by adjusting the conversion amounts of each oil quantity associated factor according to the weights of each oil quantity associated factor and then adding them.

[0128] The embodiment provides a vehicle oil amount estimation method.
