The present application relates to the technical field of oil level display, and in particular, to an oil level display method and control device.

Background technique

The statements herein merely provide background information relevant to the present application and do not necessarily constitute exemplary techniques.

Oil-powered engines mainly use gasoline or diesel in the fuel tank to run, thereby providing mechanical energy to the outside. In order to facilitate users to know the amount of oil in the tank, an oil level sensor is usually used to collect the amount of oil in the tank. However, the oil level sensor can only collect a few fixed amounts of oil, and the oil amount has a large jump amplitude. Therefore, the displayed remaining oil amount in the tank also has a large jump amplitude. In this way, the user cannot intuitively know the amount of oil in the tank. If the remaining oil level is too low, it is easy to cause the oil-driven engine to fail to operate due to insufficient refueling, resulting in poor user experience. Therefore, how to accurately display the remaining amount of fuel in the fuel tank is an urgent problem that needs to be solved.

Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments may be combined with each other without conflict.

Please refer to FIG. 1 , which is a schematic flowchart of an oil quantity display method provided by an embodiment of the present application.

As shown in Figure 1, the oil quantity display method includes steps S101 to S103.

Step S101: Obtain the output power of the oil-driven engine, and determine the fuel consumption per unit time of the oil-driven engine based on the output power.

The greater the output power of the oil-driven engine, the higher the fuel consumption per unit time of the oil-driven engine. The fuel consumption per unit time of a petrol engine can include the fuel consumption per hour, the fuel consumption per minute or the fuel consumption every 30 seconds. The fuel consumption per hour, fuel consumption per minute and fuel consumption per 30 seconds of a petrol engine can be converted to each other.

For example, a mapping relationship table between the output power range of the oil-driven engine and the fuel consumption per unit time of the oil-driven engine is established in advance. Determine the output power range in which the output power of the oil-driven engine is located, and query the mapping relationship table to obtain the fuel consumption per unit time corresponding to the output power range in which the output power of the oil-driven engine is located. Among them, through multiple rigorous tests on the corresponding relationship between the output power of the oil-driven engine and the fuel consumption per unit time, and based on the test results, the output power range of the oil-driven engine and the relationship between the output power of the oil-driven engine and the oil-driven engine were established. Mapping relationship between engine fuel consumption per unit time. For example, the mapping relationship table can be as shown in Table 1.

Table 1

Output power range	Fuel consumption per unit time
0	300ml/H
0<P<450W	476ml/H
450<P<＝900W	625ml/H
900<P<＝1350W	661ml/H
1350W<P<＝1800W	920ml/H

For example, when the output power of the oil-driven engine is 1500W, it can be determined that 1500W is in the range of 1350W<P<=1800W. Therefore, we can know that the fuel consumption of the oil-driven engine is 920ml per hour. Through conversion, we can get that the fuel consumption of the oil-driven engine is 15.3ml per minute, and the fuel consumption of the oil-driven engine every 30 seconds is 7.6ml.

Step S102: Obtain the remaining fuel percentage currently displayed by the display device and obtain the fuel consumption coefficient of the oil-driven engine.

Among them, the fuel consumption coefficient of the oil-driven engine is used to correct the remaining oil percentage displayed by the display device. The fuel consumption coefficient of the oil-driven engine can be greater than 1, can be equal to 1, or can be less than 1. The embodiment of the present application is No specific restrictions are made. In some embodiments, the initial value of the fuel consumption coefficient of the oil-driven engine is 1, and the fuel consumption coefficient will be updated according to actual conditions during actual operation. The remaining fuel percentage refers to the percentage of the remaining fuel in the fuel tank of the oil-driven engine to the full fuel volume of the fuel tank. The full fuel volume of the fuel tank is the amount of gasoline or diesel required to fill the fuel tank.

In one embodiment, the oil quantity refresh frequency is obtained, the output power of the oil-driven engine is obtained according to the oil quantity refresh frequency, and the fuel consumption per unit time of the oil-driven engine is determined based on the output power. Obtain the remaining fuel percentage currently displayed by the display device and obtain the fuel consumption coefficient of the oil-driven engine. The oil amount refresh frequency refers to the update frequency of the remaining oil amount percentage displayed by the display device. The oil amount refresh frequency can be set according to the actual situation. This is not specifically limited in the embodiment of the present application. For example, the oil quantity refresh frequency is to refresh the remaining oil quantity percentage displayed by the display device once a minute, or to refresh the remaining fuel quantity percentage displayed by the display device once every 30 seconds.

For example, if the oil quantity refresh frequency is to refresh the remaining oil quantity percentage displayed by the display device once a minute, then the output power of the oil-driven engine is obtained at a frequency of once a minute, and based on the output power, the unit time consumption of the oil-driven engine is determined. Oil volume. Obtain the remaining fuel percentage currently displayed by the display device and obtain the fuel consumption coefficient of the oil-driven engine.

For example, the output power of the oil-driven engine is obtained at 10:30, and the fuel consumption per unit time of the oil-driven engine is determined based on the obtained output power, and the fuel consumption coefficient of the oil-driven engine and the current value displayed by the display device are obtained. Remaining oil percentage. After 1 minute, that is, at 10:31, the output power of the oil-driven engine is obtained again, and the fuel consumption per unit time of the oil-driven engine is determined based on the obtained output power, and the remaining fuel volume currently displayed on the display device is obtained. percentage and obtain the fuel consumption coefficient of the oil-driven engine.

It can be understood that the output power of the oil-driven engine, the fuel consumption coefficient of the oil-driven engine, and the remaining oil percentage currently displayed on the display device will change over time. Therefore, the oil-driven engine's information is obtained according to the oil volume refresh frequency. Output power, and based on the output power, determine the fuel consumption per unit time of the oil-driven engine, and obtain the fuel consumption coefficient of the oil-driven engine and the remaining fuel percentage currently displayed on the display device, and the latest unit of the oil-driven engine can be obtained The time fuel consumption, the latest fuel consumption coefficient and the latest remaining fuel percentage currently displayed by the display device.

Among them, the fuel consumption coefficient of the oil-driven engine is updated based on the remaining oil percentage currently displayed by the display device and the remaining oil collected by the oil level sensor. By updating the fuel consumption coefficient, the consistency of the remaining fuel percentage displayed by the display device and the remaining fuel percentage calculated by the background can be ensured, and the accuracy of the remaining fuel percentage displayed by the display device can be improved.

It can be understood that when executing the oil level display method, step S101 may be executed first, and then step S102 may be executed, or step S102 may be executed first, and then step S101 may be executed, or step S101 and step S102 may be executed at the same time. Embodiments of the present application There is no specific limit on this.

Step S103: Update the remaining fuel percentage displayed by the display device based on the fuel consumption per unit time, the currently displayed remaining fuel percentage, and the fuel consumption coefficient.

Among them, the new remaining fuel percentage can be calculated through the fuel consumption per unit time, the currently displayed remaining fuel percentage and the fuel consumption coefficient, and then the remaining fuel percentage displayed by the display device is replaced with the new remaining fuel percentage. , to update the remaining fuel percentage displayed by the display device.

In one embodiment, the total fuel consumption of the oil-driven engine is calculated based on the fuel consumption per unit time and the fuel consumption coefficient. The remaining fuel percentage displayed on the display device is updated based on the total fuel consumption, the currently displayed remaining fuel percentage and the full fuel tank of the oil-driven engine. The total fuel consumption of the oil-driven engine can be accurately calculated through the fuel consumption per unit time and the fuel consumption coefficient, and then through the accurate total fuel consumption, the currently displayed remaining fuel percentage and the full fuel tank of the oil-driven engine , can accurately update the remaining oil percentage displayed by the display device.

Among them, the total fuel consumption of the oil-driven engine refers to the amount of oil consumed by the oil-driven engine within an oil quantity refresh cycle. Therefore, by calculating the product of the fuel consumption per unit time, the duration of the fuel refresh cycle and the fuel consumption coefficient, the total fuel consumption of the oil-driven engine can be obtained. The oil quantity refresh period is determined based on the oil quantity refresh frequency. For example, if the oil quantity refresh frequency is to refresh the remaining oil quantity percentage displayed by the display device once a minute, then the oil quantity refresh period is one minute. For example, the oil quantity refresh frequency is The remaining fuel percentage displayed by the display device is refreshed once every 30 seconds, and the fuel refresh cycle is 30 seconds.

For example, based on the total fuel consumption, the currently displayed remaining fuel percentage and the full fuel tank of the oil-driven engine, the method of updating the remaining fuel percentage displayed by the display device may be: calculating the currently displayed remaining fuel percentage and The product of the full fuel capacity of the fuel tank; calculate the difference between the product and the total fuel consumption, and divide the difference between the product and the total fuel consumption by the full fuel volume of the fuel tank to obtain the new remaining fuel percentage; The remaining fuel percentage shown on the display device is updated to the new remaining fuel percentage.

For example, assume that the full amount of fuel in the fuel tank is N, the fuel consumption coefficient is α, the remaining fuel percentage currently displayed by the display device is β ₁ , the fuel consumption per unit time is C, the duration of the fuel refresh cycle is T, and the new The remaining oil percentage is β ₂ , then the new remaining oil percentage is: β ₂ =(N*β ₁ -α*C*T)/N, assuming the full fuel capacity of the tank is N=3950ml, and the fuel consumption coefficient α=1 , the remaining fuel percentage currently displayed by the display device is β ₁ = 95%, the engine’s fuel consumption per unit time C = 15 ml/min, and the fuel refresh cycle is 1 minute, then the new remaining fuel percentage is: β ₂ = (3950 *95%-1*15*1)/3950=94%, the display accuracy is 1%.

For example, based on the total fuel consumption, the currently displayed remaining fuel percentage and the full fuel tank of the oil-driven engine, the method of updating the remaining fuel percentage displayed on the display device may be: dividing the total fuel consumption by the full fuel tank. The fuel consumption percentage is obtained by subtracting the fuel consumption percentage from the remaining fuel volume percentage currently displayed on the display device to obtain the new remaining fuel volume percentage. For example, the new remaining oil percentage: β ₂ =β ₁ -(α*C*T)/N)=95%-(1*15*1)/3950=94%.

In one embodiment, as shown in FIG. 2 , the updating process of the fuel consumption coefficient of the oil-driven engine includes steps S110 to S130.

Step S110: Calculate the product of the percentage of remaining oil currently displayed on the display device and the full amount of oil in the oil tank of the oil-driven engine to obtain the first remaining oil amount.

For example, if the remaining oil percentage currently displayed by the display device is 95%, and the oil tank of the oil-driven engine is full of 3950 ml, then the first remaining oil amount is: 3950*95%=3752.5 ml. It can be understood that the percentage of remaining fuel currently displayed by the display device in step S110 and the percentage of remaining fuel currently displayed by the display device in step S102 may be the same or different. For example, when step S110 and step S102 are executed simultaneously, the remaining oil percentages in these two steps are the same. For another example, when step S110 and step S102 are not executed at the same time, the remaining oil percentages in these two steps are different.

Step S120: Obtain the second remaining oil amount collected by the oil level sensor.

Wherein, the oil level sensor is used to collect the remaining oil amount of the oil tank of the oil-driven engine. The remaining oil amount of the oil tank collected by the oil level sensor can be determined as the second remaining oil amount. The oil level sensor can include a capacitive oil level sensor or Electronic oil level sensor, electronic oil level sensor can include resistive oil level sensor, voltage oil level sensor or frequency oil level sensor.

In one embodiment, multiple remaining oil quantities collected by the oil level sensor are obtained; an average remaining oil quantity is calculated based on the multiple remaining oil quantities, and the average remaining oil quantity is determined as the second remaining oil quantity. Among them, the oil level sensor can be in an oil level. Among them, the oil level sensor can collect multiple remaining oil quantities of the fuel tank within a preset time period. The preset time period can be set based on actual conditions. This is not specifically limited in the embodiments of the present application. For example, if the preset time is 1 second, the fuel level sensor collects multiple remaining fuel levels in the fuel tank within 1 second. The accuracy of the remaining oil amount can be improved by collecting multiple remaining oil amounts in the fuel tank through the oil level sensor, and taking the average of the multiple remaining oil amounts as the second remaining oil amount.

It can be understood that when executing steps S110 and S120, step S110 may be executed first, and then step S120 may be executed, or step S120 may be executed first, and then step S110 may be executed, or step S110 and step S120 may be executed at the same time. This application implements This example does not specifically limit this.

Step S130: Update the fuel consumption coefficient based on the first remaining fuel quantity and the second remaining fuel quantity.

Since the remaining oil amount displayed by the display device may be different from the remaining oil amount collected by the oil level sensor, that is, there is a deviation between the remaining oil amount displayed by the display device and the actual remaining oil amount in the fuel tank. The fuel consumption coefficient can be updated, that is, the fuel consumption coefficient can be increased or decreased, and the remaining fuel percentage of the updated display device is related to the fuel consumption coefficient, so that after the fuel consumption coefficient is updated, the fuel consumption coefficient can be updated based on the updated fuel consumption coefficient. The fuel consumption coefficient accurately updates the remaining fuel percentage displayed by the display device, thereby reducing the deviation between the remaining fuel volume displayed by the display device and the actual remaining fuel volume in the fuel tank.

In an embodiment, as shown in Figure 3, step S130 may include sub-steps S131 to sub-step S133.

Sub-step S131: When the first remaining oil amount is not equal to the second remaining oil amount, calculate the difference between the first remaining oil amount and the second remaining oil amount to obtain the oil amount deviation.

Sub-step S132: Determine the oil quantity deviation range in which the oil quantity deviation lies, and determine the correction value of the fuel consumption coefficient according to the oil quantity deviation range in which the oil quantity deviation lies.

Sub-step S133: Update the fuel consumption coefficient according to the correction value of the fuel consumption coefficient.

By when the first remaining oil amount is not equal to the second remaining oil amount, that is, there is a deviation between the remaining oil amount displayed by the display device and the actual remaining oil amount in the fuel tank, based on the oil between the first remaining oil amount and the second remaining oil amount, The correction value of the fuel consumption coefficient is determined based on the quantity deviation, and then the fuel consumption coefficient is updated through the correction value. In this way, the remaining fuel percentage displayed by the display device can be accurately updated based on the updated fuel consumption coefficient, thereby reducing the remaining fuel quantity displayed by the display device. The deviation between the fuel level and the actual remaining fuel level in the tank.

For example, the mapping relationship table between the pre-established oil quantity deviation range and the correction value of the fuel consumption coefficient is queried to obtain the correction value corresponding to the oil quantity deviation range in which the oil quantity deviation lies. According to the correction value of the fuel consumption coefficient, the fuel consumption coefficient is updated, that is, the correction value of the fuel consumption coefficient is accumulated with the currently stored fuel consumption coefficient to obtain a new fuel consumption coefficient. The mapping relationship table between the oil quantity deviation range and the correction value of the fuel consumption coefficient can be established based on multiple tests, which is not specifically limited in the embodiment of the present application.

For example, according to the correction value of the fuel consumption coefficient, the method of updating the fuel consumption coefficient may include: accumulating the correction value of the fuel consumption coefficient and the currently stored fuel consumption coefficient to obtain a new fuel consumption coefficient, And replace the currently stored fuel consumption coefficient with the new fuel consumption coefficient to update the fuel consumption coefficient.

The correction value of the fuel consumption coefficient includes a positive correction value or a negative correction value. When the difference between the first remaining fuel quantity and the second remaining fuel quantity is greater than zero, the correction value of the fuel consumption coefficient is a positive number. Correction value, when the difference between the first remaining oil amount and the second remaining oil amount is less than zero, the correction value of the fuel consumption coefficient is a negative correction value. For example, if the percentage of remaining oil displayed by the display device is 80%, and the full oil volume of the fuel tank is 3950ml, then the first remaining oil volume can be calculated as: 3950*80%=3160ml, and the second remaining oil volume collected by the oil level sensor The amount is 75% of the full tank capacity, that is, the second remaining oil amount is: 3950*75%=2962.5ml. The oil amount deviation is calculated through calculation: 3160-2962.5=197.5ml. If the oil amount deviation is 197.5ml, The correction value corresponding to the range of 180ml to 200ml is 0.35, then it can be determined that the correction value of the fuel consumption coefficient is 0.35. If the currently stored fuel consumption coefficient is 1, update the fuel consumption coefficient according to the formula, that is, α = α + Δα, Δα is the correction value of the fuel consumption coefficient, and the new fuel consumption coefficient can be calculated as: α = α+Δα=1+0.35=1.35.

For another example, if the percentage of remaining oil displayed by the display device is 72%, and the full oil volume of the fuel tank is 3950ml, then the first remaining oil volume can be calculated as: 3950*72%=2844ml, and the second remaining oil volume collected by the oil level sensor is The oil volume is 75% of the full tank capacity, that is, the second remaining oil volume is: 3950*75%=2962.5ml. The oil volume deviation is calculated through calculation: 2844-2962.5=-118.5ml. If the oil volume deviation is -118.5ml The correction value corresponding to the range of -100ml to -120ml is -0.2, then the correction value of the fuel consumption coefficient can be determined to be -0.2. If the currently stored fuel consumption coefficient is 1, the fuel consumption is updated according to the formula The fuel consumption coefficient is α=α+Δα, Δα is the correction value of the fuel consumption coefficient, and the new fuel consumption coefficient can be calculated as: α=α+Δα=1-0.2=0.8.

In an embodiment, as shown in Figure 4, step S130 may include sub-steps S134 to sub-step S136.

Sub-step S134: When the first remaining oil amount is not equal to the second remaining oil amount, obtain the third remaining oil amount collected previously by the oil level sensor.

Sub-step S135: Determine the correction value of the fuel consumption coefficient based on the first remaining oil amount, the second remaining oil amount and the third remaining oil amount.

Sub-step S136: Update the fuel consumption coefficient according to the correction value of the fuel consumption coefficient.

When the first remaining oil amount is not equal to the second remaining oil amount, that is, there is a deviation between the remaining oil amount displayed by the display device and the actual remaining oil amount of the fuel tank, the actual remaining oil amount of the fuel tank, the remaining oil amount displayed by the display device, and The last actual remaining fuel quantity in the fuel tank can more accurately determine the correction value of the fuel consumption coefficient, so that the fuel consumption coefficient can be updated more accurately, so that the remaining fuel displayed by the display device can be updated more accurately based on the updated fuel consumption coefficient. The oil volume percentage is further reduced, thereby further reducing the deviation between the remaining oil volume displayed by the display device and the actual remaining oil volume in the fuel tank.

For example, when the deviation between the first remaining oil amount and the second remaining oil amount is greater than the preset deviation threshold, the third remaining oil amount collected previously by the oil level sensor is obtained. The correction value of the fuel consumption coefficient is determined based on the first remaining oil amount, the second remaining oil amount and the third remaining oil amount. According to the correction value, the fuel consumption coefficient is updated. By updating the fuel consumption coefficient when the deviation between the first remaining fuel quantity and the second remaining fuel quantity is greater than the preset deviation threshold, there is no need to update the fuel consumption coefficient every time, which not only reduces the fuel consumption coefficient The number of updates saves computing resources and ensures that the deviation between the remaining fuel amount displayed by the display device and the actual remaining oil amount in the fuel tank is small.

Among them, the third remaining oil amount collected last time can be the average of multiple remaining oil amounts collected by the oil level sensor last time. The preset deviation threshold can be set based on the actual situation. This is not done in the embodiment of this application. Specific limitations. For example, the preset deviation threshold is 5ml, 15ml or 20ml, etc. When the deviation between the first remaining oil amount and the second remaining oil amount is less than the preset deviation threshold, the fuel consumption coefficient is not updated.

For example, based on the first remaining oil amount, the second remaining oil amount and the third remaining oil amount, the correction value of the fuel consumption coefficient may be determined by: calculating the difference between the first remaining oil amount and the second remaining oil amount. value to obtain the first oil quantity deviation; calculate the difference between the third remaining oil quantity and the second remaining oil quantity to obtain the second oil quantity deviation; divide the first oil quantity deviation by the second oil quantity deviation to obtain the fuel consumption The correction value of the coefficient. Among them, the correction value of the fuel consumption coefficient includes a positive correction value or a negative correction value. When the first fuel quantity deviation and the second fuel quantity deviation are both positive or negative values, the correction value of the fuel consumption coefficient is a positive correction value. value, the correction value of the fuel consumption coefficient includes a positive correction value or a negative correction value. When one of the first fuel quantity deviation and the second fuel quantity deviation is a negative value and the other is a positive value, the correction value of the fuel consumption coefficient is a negative number. Correction value.

For example, if the percentage of remaining oil displayed by the display device is 80%, and the full oil volume of the fuel tank is 3950ml, then the first remaining oil volume can be calculated as: 3950*80%=3160ml, and the second remaining oil volume collected by the oil level sensor The amount is 75% of the full amount of the fuel tank, that is, the second remaining oil amount is: 3950*75% = 2962.5ml. The third remaining oil amount collected by the oil level sensor is 100% of the full amount of the fuel tank, that is, the third remaining amount. The oil volume is 3950ml. The first oil volume deviation is calculated through calculation: 3160-2962.5=197.5ml. The second oil volume deviation is: 3950-2962.5=987.5ml. 197.5 divided by 987.5 is equal to 0.2. Therefore, the fuel consumption coefficient The correction value is 0.2. If the currently stored fuel consumption coefficient is 1, the fuel consumption coefficient is updated according to the formula, that is: α = α + Δα, Δα is the correction value of the fuel consumption coefficient, and the new fuel consumption can be calculated The quantity coefficient is: α=α+Δα=1+0.2=1.2. By increasing the fuel consumption coefficient when the remaining oil amount displayed by the display device is greater than the actual remaining oil amount in the fuel tank, the deviation between the remaining oil amount displayed by the display device and the actual remaining oil amount in the fuel tank can be quickly reduced.

For another example, if the percentage of remaining oil displayed by the display device is 70%, and the full oil volume of the fuel tank is 3950ml, then the first remaining oil volume can be calculated as: 3950*70%=2765ml, and the second remaining oil volume collected by the oil level sensor is The oil volume is 75% of the full fuel capacity of the fuel tank, that is, the second remaining oil volume is: 3950*75%=2962.5ml. The third remaining oil volume collected by the oil level sensor is 100% of the full fuel volume of the fuel tank, that is, the third remaining oil volume is: The remaining oil volume is 3950ml. Through calculation, the first oil volume deviation is: 2962.5-3160=-197.5ml. The second oil volume deviation is: 3950-2962.5=987.5ml. -197.5 divided by 987.5 equals -0.2. Therefore, the consumption The correction value of the fuel consumption coefficient is -0.2. If the currently stored fuel consumption coefficient is 1, the fuel consumption coefficient is updated according to the formula, that is: α = α + Δα, Δα is the correction value of the fuel consumption coefficient, which can be calculated The new fuel consumption coefficient is obtained: α=α+Δα=1-0.2=0.8. By reducing the fuel consumption coefficient when the remaining oil amount displayed by the display device is less than the actual remaining oil amount of the fuel tank, the deviation between the remaining oil amount displayed by the display device and the actual remaining oil amount of the fuel tank can be quickly reduced.

It can be understood that steps S110 to S130 can be performed before or after step S101, step S102 or step S103, or can be performed before the step of "obtaining the fuel consumption coefficient of the oil-driven engine" in step S102. This application The implementation does not impose specific restrictions on this.

Exemplarily, the solution for steps S110 to S130 to be executed before the step of "obtaining the fuel consumption coefficient of the oil-driven engine" in step S102 is to obtain the output power of the oil-driven engine, and determine the fuel consumption of the oil-driven engine based on the output power. fuel consumption per unit time; obtain the remaining fuel percentage currently displayed by the display device; calculate the product of the remaining fuel percentage currently displayed by the display device and the full fuel capacity of the oil tank of the oil-driven engine to obtain the first remaining fuel volume; obtain the oil level The second remaining oil amount collected by the sensor; update the fuel consumption coefficient according to the first remaining oil amount and the second remaining oil amount; obtain the fuel consumption coefficient of the oil-driven engine; based on the fuel consumption per unit time and the currently displayed remaining oil amount The fuel percentage and fuel consumption coefficient update the remaining fuel percentage displayed by the display device.

Exemplarily, steps S110 to S130 are executed before step S101 as follows: calculating the product of the percentage of remaining oil currently displayed on the display device and the full amount of oil in the oil tank of the oil-driven engine to obtain the first remaining oil amount; and obtaining the oil level sensor.

Step S201: Obtain the fuel volume record value of the fuel tank and the remaining fuel volume in the fuel tank collected by the fuel level sensor.

Step S202: When the remaining oil amount in the fuel tank is less than the recorded value of the oil amount in the fuel tank, obtain the output power of the oil-driven engine, and determine the fuel consumption per unit time of the oil-driven engine based on the output power.

Step S203: Obtain the remaining fuel percentage currently displayed by the display device and obtain the fuel consumption coefficient of the oil-driven engine.

In one embodiment, when the remaining oil amount in the fuel tank is less than the recorded value of the fuel tank oil amount, the recorded value of the fuel tank oil amount is updated to the remaining oil amount in the fuel tank. By updating the fuel tank fuel volume record value to the remaining fuel volume in the fuel tank when the oil-driven engine is in working condition and consuming gasoline or diesel in the fuel tank, the accuracy of the fuel tank fuel volume record value can be ensured.

In one embodiment, when the remaining oil amount in the fuel tank is greater than the recorded oil amount in the fuel tank, the remaining oil amount percentage displayed by the display device and the recorded oil amount in the fuel tank are updated according to the remaining oil amount in the fuel tank. That is, divide the remaining fuel volume in the fuel tank by the full fuel volume in the fuel tank to obtain the new remaining fuel volume percentage, replace the remaining fuel volume percentage displayed by the display device with the new remaining fuel volume percentage, and update the fuel tank fuel volume record value to The amount of fuel remaining in the tank. By updating the remaining fuel percentage displayed by the display device and the fuel tank fuel record value based on the actual remaining fuel quantity in the fuel tank when refueling the fuel tank, the accuracy of the remaining fuel percentage and the fuel tank fuel record value can be improved.

In some embodiments, whether the oil-driven engine is in a working state can also be determined by the rotation speed of the oil-driven engine. For example, obtain the current speed of the oil-driven engine. When the current speed of the oil-driven engine is greater than the preset speed threshold, obtain the output power of the oil-driven engine, and determine the fuel consumption per unit time of the oil-driven engine based on the output power. Obtain the remaining fuel percentage currently displayed by the display device and obtain the fuel consumption coefficient of the oil-driven engine; update the remaining fuel percentage displayed by the display device based on the fuel consumption per unit time, the currently displayed remaining fuel percentage and the fuel consumption coefficient. .
