Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve the accuracy of the determined fuel quantity when determining the fuel quantity of a fuel system, the embodiment of the invention provides a fuel quantity determining method, a fuel quantity determining device and electronic equipment.
The execution main body of the fuel quantity determination method provided by the embodiment of the invention can be a fuel quantity determination device. The device can be used in electronic equipment containing a fuel system. In a specific application, the electronic device may be a drone, but is not limited thereto.
In the embodiment of the invention, empirical data of oil consumption values of an engine of a fuel system under different throttle opening degrees and rotating speeds are obtained through multiple tests in advance, and the corresponding relation between a plurality of preset working conditions and the oil consumption values is set according to the empirical data, wherein each preset working condition comprises a preset throttle opening degree and a preset rotating speed. It should be noted that the fuel quantity determining method provided by the embodiment of the invention describes the process of determining the fuel quantity of the fuel system once. In practice, the method may be repeatedly performed while the fuel system is in operation. For example, the fuel amount of the fuel system is determined every 20 milliseconds, and then the method is executed every 20 milliseconds.
First, a fuel amount determination method provided by an embodiment of the present invention is explained in detail. As shown in fig. 1, the method for determining the amount of fuel provided by the embodiment of the invention may include the following steps:
s101: and acquiring the current throttle opening and the current rotating speed of the fuel system, and acquiring a reference fuel quantity.
Wherein the reference fuel amount is a fuel amount read from a fuel amount sensor of the fuel system when the reference fuel amount is obtained for the first time; when the reference fuel amount is not obtained for the first time, the reference fuel amount is the last determined fuel amount of the fuel system. That is, after each start of the fuel system, when the action of obtaining the current throttle opening and the rotating speed of the fuel system is executed for the first time, the fuel quantity is read from the fuel quantity sensor of the fuel system, and the reference fuel quantity is obtained; when the action of obtaining the current throttle opening and the rotating speed of the fuel system is not executed for the first time, the last determined fuel quantity of the fuel system is obtained, and therefore the reference fuel quantity is obtained. It will be appreciated that the fuel system is typically started upon start-up of the device to which it belongs, and that the device is still in a static mode of operation, so that the fuel tank of the fuel system is not sloshing, and the fuel quantity read from the fuel quantity sensor is relatively accurate. Therefore, when the reference fuel amount is obtained for the first time, the fuel amount read by the fuel amount sensor may be used as the reference fuel amount.
S102: and determining the oil consumption value of the fuel system under the current throttle opening and rotating speed according to the corresponding relation between the preset working conditions and the oil consumption value.
The preset working conditions comprise a preset throttle opening and a preset rotating speed.
In practice, when the fuel consumption is measured in advance under various predetermined operating conditions, the measured fuel consumption is usually measured in liters/hour. At this time, the fuel consumption value in liters/hour may be converted into a fuel consumption value in a certain period, and then set in the corresponding relationship between the preset operating condition and the fuel consumption value. Here, the determination period is an execution period for executing the fuel amount determination method of the invention.
In the embodiment of the invention, the specific implementation modes of determining the oil consumption value of the fuel system under the current throttle opening and rotating speed can be various according to the corresponding relation between the preset working conditions and the oil consumption value.
For example, in a first implementation manner, when the pre-tested data volume is sufficient and various possible throttle openings and rotation speeds are tested, the current throttle opening and oil consumption value of the fuel system at the rotation speed can be directly read from the corresponding relationship.
In a second implementation manner, a two-dimensional table shown in fig. 2 may be formed by using a preset correspondence relationship between the operating conditions and the fuel consumption values. In the two-dimensional table, each fuel consumption value corresponds to one throttle opening and one rotating speed. Therefore, the fuel consumption value of the fuel system under the current throttle opening and the current rotating speed can be calculated by utilizing a two-dimensional piecewise linear interpolation method according to the corresponding relation between the preset working condition and the fuel consumption value. In a particular application, the data in the table may form a three-dimensional plane or surface. Wherein, the first dimension is the opening degree of a throttle valve; the second dimension is the rotation speed, and the third dimension is the fuel consumption value. After the current throttle opening and the current rotating speed of the fuel system are obtained, a small part of area where the current throttle opening and the current rotating speed are located can be found in the plane or the curved surface. Since the part of the region already has a plurality of known values, the function of the part of the region can be fitted. After the function is fitted, the current throttle opening and the current rotating speed are substituted into the function, and the oil consumption value corresponding to the current throttle opening and the current rotating speed can be calculated.
Of course, in a third implementation manner, the preset corresponding relationship between the operating condition and the fuel consumption value may be: a predetermined fitting function in which the independent variables are: the opening degree of a throttle valve and the rotating speed are controlled, and the dependent variable is the oil consumption value. And the preset fitting function is a function obtained by fitting a plurality of groups of preset working conditions and oil consumption values.
S103: and subtracting the determined oil consumption value from the reference fuel quantity to obtain a difference value, and taking the difference value as the current fuel quantity of the fuel system.
It is understood that after the execution of S103 is completed, the current determination period is ended, and the next determination period can be directly entered, and so on, until a command to stop determining the fuel amount is received. In each determination cycle, the steps described in one pass of S101-S103 are performed.
In addition, the preset corresponding relationship between the operating condition and the fuel consumption value may be a corresponding relationship under a preset external environment parameter. Therefore, in the embodiment of the present invention, after subtracting the determined fuel consumption value from the reference fuel amount to obtain a difference value, and before using the difference value as the fuel amount of the fuel system, the method may further include:
obtaining current external environment parameters;
determining a value of each of the current external environment parameters and a value of each of the preset external environment parameters for each of the current external environment parameters; calculating a correction parameter for the difference value using the determined two values;
and correcting the difference value by using the calculated correction parameter.
The external environment parameters may include altitude, air temperature, atmospheric pressure, and the like.
It can be understood that the fuel consumption of the fuel system is affected by external environmental parameters. Therefore, in order to further improve the accuracy of the determined fuel amount, when the current external environment is different from the environment defined by the preset external environment parameters, the difference value can be corrected according to the difference between the current external environment and the preset external environment parameters, so that the accurate fuel amount is obtained.
In practical application, each parameter of the external environment parameters can be pre-determined, the parameter is traversed under the condition that other parameters are fixed values, and the fuel consumption value of the fuel system is measured in the traversing process. Thus, a correction parameter of the parameter to the fuel consumption value can be calculated according to the measured data. Therefore, after subtracting the determined fuel consumption value from the reference fuel amount, the difference can be corrected by using the correction parameter. Here, the correction parameter may be a correction amount per unit, a correction factor, or the like, but is not limited thereto. For example, for a parameter of air temperature, the correction parameter may be an amount of increase or decrease in the difference value for every degree of celsius higher or lower.
It will be appreciated that a more accurate fuel quantity for the fuel system can be obtained after the difference is corrected for each parameter.
In the fuel quantity determining method provided by the embodiment of the invention, the corresponding relation between a plurality of preset working conditions and the fuel consumption value is preset for a fuel system. The preset working conditions comprise a preset throttle opening and a preset rotating speed. Therefore, when the current throttle opening and the current rotating speed of the fuel system are obtained, the fuel consumption value of the fuel system at the current throttle opening and the current rotating speed can be determined from the corresponding relation. And then, the last determined fuel quantity of the fuel system is used as a reference fuel quantity, and the determined fuel consumption value is subtracted, so that the current fuel quantity of the fuel system can be obtained. In this way, even if the measured value of the fuel quantity sensor is inaccurate, the determined fuel quantity is not affected. According to the scheme, when the fuel quantity of the fuel system is determined, the current throttle opening and the rotating speed of the fuel system, the reference fuel quantity and the preset corresponding relation between the plurality of preset working conditions and the fuel consumption value are depended, and compared with an oil quantity sensor in the prior art, the fuel quantity sensor is not affected by liquid level shaking, so that the accuracy of the fuel quantity can be improved through the scheme.
On the basis of the fuel quantity determination method shown in fig. 1, another fuel quantity determination method is provided in the embodiment of the present invention, and as shown in fig. 3, the method may include the following steps:
s310: monitoring a measured value of an oil mass sensor of the fuel system;
s320: judging whether a first measured value smaller than or equal to a preset threshold value is monitored, and executing S3202-S3204 when the judgment result is yes; when the determination result is no, S3201 is executed;
s3201: taking the measured value of the oil quantity sensor as the current fuel quantity of the fuel system;
s3202: obtaining the current throttle opening and the rotating speed of a fuel system, and obtaining a reference fuel quantity;
s3203: determining the oil consumption value of the fuel system under the current throttle opening and rotating speed according to the corresponding relation between a plurality of preset working conditions and the oil consumption value;
s3204: and subtracting the determined oil consumption value from the reference fuel quantity to obtain a difference value, and taking the difference value as the current fuel quantity of the fuel system.
S3202-S3204 are the same as the above-mentioned S101-S103, and are not described herein again.
It can be understood that in the case of a fuel system with a sufficient amount of fuel in the tank, the fuel level will not slosh much, and the measurement value of the fuel sensor will be relatively accurate. Therefore, before the first measured value which is less than or equal to the preset threshold value is monitored, the measured value of the fuel quantity sensor can be directly used as the current fuel quantity of the fuel system.
In addition, in order to simplify the process, after the first measured value less than or equal to the preset threshold value is monitored and S3202 to S3204 are sequentially executed, in the process of determining the fuel amount in a new round, the process may directly return to S3202 without executing S310 and S320.
For example, as shown in fig. 4, when the first measured value less than or equal to the preset threshold is not monitored as the result of the determination at S42, S41 is executed in a loop, that is, the fuel amount of the fuel system is determined in the measurement mode until the first measured value less than or equal to the preset threshold is monitored. When the first measured value less than or equal to the preset threshold value is monitored as a result of the judgment at S42, execution of the loop S43, that is, the fuel amount of the fuel system is determined in the estimation mode, until the determination of the fuel amount is stopped as a result of the judgment at S44. The manner of determining the fuel amount of the fuel system in the measurement mode in S41 is the same as the manner of determining the fuel amount of the fuel system in S3201, and the manner of determining the fuel amount of the fuel system in the estimation mode in S43 is the same as the manner of determining the fuel amount of the fuel system in S3202-S3204.
In practical application, the highest actual fuel quantity can be selected as the preset threshold value from each actual fuel quantity when the fuel quantity monitored by the fuel quantity sensor is inconsistent with the actual fuel quantity. Or, after a low oil conservation quantity is added on the basis of the real oil quantity, the summation result is used as a preset threshold value. Thus, the estimation mode can be started in advance, and the condition that the determined fuel quantity is inaccurate near the preset threshold value is avoided.
Corresponding to the method for determining the fuel quantity, the embodiment of the invention also provides a device for determining the fuel quantity.
It should be noted that the fuel quantity determining device provided by the embodiment of the present invention may be used in an electronic device including a fuel system. In a specific application, the electronic device may be a drone, but is not limited thereto.
