Referring to fig. 1, fig. 1 is a schematic structural diagram illustrating an oil amount calculating device according to an embodiment of the present application.
As shown in fig. 1, the fuel quantity calculation means may include one or more fuel quantity sensors, one or more controllers, and one or more memories. The oil quantity sensor or the oil quantity sensors can be applied to detection of oil consumption in multiple fields, for example, the oil quantity sensor in the embodiment of the application can be used for detecting liquid level change in a vehicle oil tank so as to obtain instantaneous oil consumption of a vehicle, further obtain oil consumption speed of the vehicle and provide more intuitive oil quantity judgment for a user. Possibly, the fuel quantity sensor can be applied to the field of automotive electronics, mainly focuses on vehicle fuel quantity detection and is generally arranged in a vehicle fuel tank. When the specific oil quantity sensor is applied to a vehicle, under the condition that the vehicle runs on a flat road or on an uphill or on a downhill or in an emergency stop, the controller can receive an electric signal which is sent by the oil quantity sensor and used for reflecting instantaneous oil consumption and the running speed of the vehicle, calculate the oil consumption speed of the vehicle and further display the accurate residual oil quantity on an instrument of the vehicle. Possibly, the oil quantity sensor can be applied to the field of ferry transportation, mainly focuses on detecting the oil quantity of a steamship and can be generally arranged in a steamship oil tank. When the specific oil quantity sensor is applied to ship transportation, under the condition that a ship is in a large sea surface wave or the sea surface is stable, the controller can receive an electric signal which is sent by the oil quantity sensor and used for reflecting instantaneous oil consumption and the running speed of the ship, the oil consumption speed of the ship is obtained through calculation, and then accurate residual oil quantity is displayed on a display interface of the ship.
The one or more controllers may be a Central Processing Unit (CPU), a single chip, a Programmable Logic Controller (PLC), or the like, and for example, may be configured to receive an electric signal sent by the oil amount sensor and reflecting the instantaneous oil consumption, perform conversion Processing on the electric signal, and obtain the speed to calculate the oil consumption speed and the remaining oil amount corresponding to the oil consumption speed.
The one or more memories may be used to store data calculated by the one or more controllers, such as the fuel consumption rate and the remaining fuel amount corresponding to the fuel consumption rate. Specifically, the fuel quantity calculating device can further comprise a display screen electrically connected with one or more controllers, or a display meter. The display screen, or display instrument, may be used to display data corresponding to data calculated by one or more controllers, such as the amount of remaining fuel calculated by the controller. Specifically, the fuel amount calculating means may further include a speaker. The loudspeaker can be used for playing prompt information or early warning information correspondingly generated according to the data calculated by the controller, for example, when the residual oil amount calculated by the controller is only one tenth, the early warning information of 'the current oil amount is insufficient' is played so as to remind a user of refueling in time.
In the embodiment of the application, the oil quantity sensor can be applied to the field of automotive electronics. Specifically, as shown in fig. 1, the instantaneous oil consumption of the vehicle during current running is obtained, after the controller arranged in the vehicle receives an electric signal corresponding to the instantaneous oil consumption, the instantaneous oil consumption is determined through circuits such as signal processing, amplification and conversion, and the damping speed is determined based on the running speed of the current vehicle. Furthermore, the controller calculates the oil consumption speed of the current vehicle at the running speed according to the damping speed and the instantaneous oil consumption, and determines the current remaining oil amount corresponding to the oil consumption speed, so that the phenomenon of instrument jump can be avoided, and more accurate and intuitive oil amount judgment is brought to a user.
It should be noted that the oil amount sensor and the oil amount calculating device provided in the embodiments of the present application are not limited to the application in the above-mentioned fields, and are not limited to the specific application.
The method for calculating the oil amount provided by the embodiment of the present application is described in detail below with reference to fig. 2.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for calculating an oil amount according to an embodiment of the present application.
As shown in fig. 2, the oil amount calculation method may specifically include:
Specifically, taking the application of the method in the field of automotive electronics as an example, the current running speed of the vehicle is acquired. Possibly, when the vehicle runs on a smooth road surface, the running state of the vehicle is smooth and has no resistance, and the obtained running speed of the vehicle can be regarded as the actual running speed. It is possible that when the vehicle travels on an uphill road section, the traveling state of the vehicle fluctuates and there is resistance in the traveling direction, and the acquired traveling speed of the vehicle may be considered to be greater than the actual traveling speed. Possibly, when the vehicle runs on the downhill road section, the running state of the vehicle fluctuates and extra driving force exists in the running direction, and the obtained running speed of the vehicle can be considered to be smaller than the actual running speed.
It is understood that, specifically, when the vehicle runs on a smooth road surface, the actual fuel consumption speed may be determined according to the running speed of the vehicle, for example, when the running speed of the vehicle is higher, the current fuel consumption speed of the vehicle is also higher, and when the running speed of the vehicle is lower, the current fuel consumption speed of the vehicle is also lower. However, in the actual driving process, when the vehicle is driving on an uphill road section, the actual fuel consumption speed may not be determined corresponding to the driving speed of the vehicle, for example, when the driving speed of the vehicle is relatively high, the current fuel consumption speed of the vehicle is greater than the fuel consumption speed corresponding to the same driving speed when the vehicle is driving on a smooth road, and when the driving speed of the vehicle is relatively low, the current fuel consumption speed of the vehicle is still greater than the fuel consumption speed corresponding to the same driving speed when the vehicle is driving on a smooth road. For example, when the driving speed of the vehicle is relatively high, the current fuel consumption speed of the vehicle is less than the fuel consumption speed corresponding to the same driving speed when the vehicle is driven on a smooth road, and when the driving speed of the vehicle is relatively low, the current fuel consumption speed of the vehicle is still less than the fuel consumption speed corresponding to the same driving speed when the vehicle is driven on a smooth road. Specifically, the vehicle may be running on a multi-traffic light road section, the vehicle is in a continuous stop-and-go state, the running speed of the vehicle is always slow, but the fuel consumption speed of the vehicle is high due to continuous sudden stop and sudden start, and the running speed of the vehicle cannot be determined correspondingly.
Further, according to the acquired current running speed of the vehicle, a damping speed corresponding to the current running speed can be determined. The running speed of the vehicle may not be always at a constant value during running but within a range of fluctuation up and down, and the damping speed may be understood as a speed that quickly returns the current actual running speed of the vehicle to a speed close to the acquired running speed or reduces the amplitude of fluctuation until the speed is close to the acquired running speed. Possibly, when the obtained running speed is larger, the corresponding damping speed is also larger, so that the actual running speed is quickly close to the obtained running speed, and the filtering time is shorter. Possibly, when the acquired running speed is small, the corresponding damping speed will also be small, the time for which the actual running speed approaches the acquired running speed will also be slow, and the filtering time will be long.
In the embodiment of the application, the current running speeds in different intervals can correspond to different damping speeds.
Specifically, the actual vehicle correspondingly obtains the damping speed according to the current running speed during running, and the running speed and the damping speed can be regarded as a direct proportion relation. In order to improve the rapidity and the accuracy of determining the damping speed, the running speed of the vehicle can be divided into a plurality of intervals, and each interval can correspond to one damping speed respectively. In particular, the travel speed of the vehicle may be divided into sections at intervals of 10 km/hour, such as 0-10 km/hour, 10-20 km/hour, 20-30 km/hour, and so on, for example when the travel speed of the vehicle is 35 km/hour, it may be understood that the travel speed of the vehicle is in the interval of 30-40 km/hour. Further, each interval may correspond to a damping speed, for example, the damping speed corresponding to the interval of 10-20 km/h may be set to be X1, the damping speed corresponding to the interval of 20-30 km/h may be set to be X2, and X1 is smaller than X2 in the embodiment of the present application.
It should be noted that each of the above mentioned intervals may correspond to a damping speed. The specific interval includes a plurality of continuous running speeds, the damping speed corresponding to each running speed can be different, and in order to make the damping speed corresponding to each interval more representative, the average value of the damping speeds corresponding to all the running speeds in one interval can be preferably taken as the damping speed corresponding to the interval.
It should be noted that, when the damping speed determined according to the acquired vehicle running speed is applied to a smooth road section where the vehicle runs, it is possible that when the running speed is higher, the corresponding damping speed is higher, and the actual fuel consumption speed is also higher. When the running speed is lower, the corresponding damping speed is lower, the actual oil consumption speed is also lower, and the condition that the oil consumption speed of the vehicle is determined according to the damping speed can be met on the basis. However, when the method is applied to the vehicle running on the uphill road section, when the obtained running speed is consistent with the speed of the vehicle running on the smooth road section, the actual current oil consumption speed is greater than the oil consumption speed of the vehicle running on the smooth road section. When the method is applied to the situation that the vehicle runs on the downhill road section, when the obtained running speed is consistent with the speed of the vehicle on the smooth running road section, the actual current oil consumption speed is smaller than the oil consumption speed of the vehicle on the smooth running road section. By combining the above, it can be known that the damping speed corresponding to the running speed of the vehicle cannot meet the actual fuel consumption condition of the vehicle.
Specifically, the oil consumption parameter includes an average oil consumption value and a maximum oil consumption limit value in a preset time period. The average fuel consumption value can be obtained by obtaining the average value of the instantaneous fuel consumption in the preset time period based on the fuel quantity sensor. For example, 10 instantaneous fuel consumption speeds can be acquired within 0-10 seconds (the frequency of the fuel quantity sensor acquiring signal can be set by self), and the average fuel consumption within 0-10 seconds is calculated based on the 10 instantaneous fuel consumption speeds. The maximum fuel consumption limit, which is understood to be the maximum instantaneous fuel consumption speed during the driving of the vehicle, may be determined according to the attribute parameters of the current vehicle, for example, the maximum fuel consumption limits may be different for different types of vehicles, and a fixed maximum fuel consumption limit may be associated with a vehicle or a type of vehicle.
Specifically, a schematic flow chart for determining the current speed provided by the embodiment of the present application as shown in fig. 3 can be referred to.
As shown in fig. 3, determining the current oil consumption speed based on the damping speed and the oil consumption parameters specifically includes:
Specifically, in order to realize real-time detection of the current remaining oil amount during the running process of the vehicle, the average value of the instantaneous oil consumption speed in the interval can be obtained according to the preset time interval, and the ratio can be obtained by calculation in combination with the maximum limit value of the instantaneous oil consumption in the attribute parameters of the vehicle. The preset time interval may be 10 seconds, 15 seconds, 20 seconds, etc., and preferably 15 seconds. Specifically, when the preset time interval is 15 seconds, the vehicle can obtain 15 instantaneous oil consumption speeds according to the oil quantity sensor, and sends the 15 instantaneous oil consumption speeds to the controller, and the controller calculates the average value of the 15 instantaneous oil consumption speeds and the ratio of the average value to the maximum limit value of the instantaneous oil consumption set by the vehicle.
It should be noted that, in order to ensure the accuracy of calculating the current fuel consumption speed, the preset time interval herein may also be used to obtain the running speed of the vehicle, that is, the running speed of the vehicle may be obtained within the preset time interval, and the corresponding damping speed is determined based on the running speed of the current vehicle.
Specifically, the current fuel consumption speed of the vehicle can be calculated by the following formula (1).
In the above formula (1), Damp _ run _ fuel _ delay x may be represented as a damping speed corresponding to a driving speed of the current vehicle within a preset time interval, IFC _ Avg may be represented as an average value of instantaneous fuel consumption speeds of the current vehicle within the preset time interval, IFC _ Max may be represented as a maximum value of the instantaneous fuel consumption speeds of the current vehicle, and the current fuel consumption speed of the vehicle within the preset time interval may be obtained by substituting data into the above formula (1).
Specifically, when the above formula (1) is applied to a smooth driving section of a vehicle, it is possible that when the driving speed is high, the corresponding damping speed Damp _ run _ full delta is high, the IFC _ Avg is also high according to the instantaneous fuel consumption of the vehicle, and the actual fuel consumption speed is also high. When the running speed is low, the corresponding damping speed Damp _ run _ full delay X is low, the IFC _ Avg is low according to the instantaneous fuel consumption of the vehicle, the actual fuel consumption speed is low, and the condition of determining the fuel consumption speed of the vehicle can be met based on the fact. Specifically, when the above equation (1) is applied to the vehicle driving on the uphill road section, when the acquired driving speed coincides with the speed of the vehicle driving on the smooth road section, the corresponding damping speed Damp _ run _ full delta x is kept consistent, and IFC _ Max is kept constant, but the current IFC _ Avg is greater than the IFC _ Avg when the vehicle is driving on the smooth road section, then the current fuel consumption speed is increased relative to the fuel consumption speed of the vehicle on the smooth road section. Specifically, when the above formula (1) is applied to the case where the vehicle runs on the downhill section, when the acquired running speed coincides with the speed of the vehicle on the running smooth section, the corresponding damping speed Damp _ run _ full delta x remains the same, and IFC _ Max remains constant, but the current IFC _ Avg is smaller than the IFC _ Avg when the vehicle runs on the smooth section, and then the current fuel consumption speed is reduced relative to the fuel consumption speed of the vehicle on the running smooth section. Possibly, when the above formula (1) is applied to the situation that the vehicle runs on a road section with multiple traffic lights, the vehicle is in a continuous stop-and-go state, the running speed of the vehicle is always slow, but the average value IFC _ Avg of the instantaneous fuel consumption speed of the vehicle is larger than the IFC _ Avg of the vehicle when the vehicle runs on a smooth road section due to continuous sudden stop and sudden start, and then the current fuel consumption speed of the vehicle is increased relative to the fuel consumption speed of the vehicle when the vehicle runs on the smooth road section.
By combining the above, it can be known that the current fuel consumption speed of the vehicle calculated based on the above formula (1) satisfies the fuel consumption condition of the actual vehicle.
And step 203, determining the residual oil quantity according to the current oil consumption speed.
Specifically, after the current fuel consumption speed is calculated, the current remaining fuel quantity of the vehicle can be determined by combining the initial remaining fuel quantity of the vehicle. For example, the controller acquires the initial residual oil quantity of the vehicle before starting, the running speed of the vehicle and at least one instantaneous oil consumption speed acquired by the oil quantity sensor in the interval are acquired according to a preset time interval, the controller determines the damping speed based on the running speed of the vehicle and calculates the average value of the instantaneous oil consumption based on the at least one instantaneous oil consumption speed, and the maximum values of the damping speed, the instantaneous oil consumption speed and the instantaneous oil consumption of the vehicle are substituted into the formula (1) to obtain the oil consumption speed in the preset time interval. Further, the oil consumption of the current vehicle in the preset time interval can be obtained based on the oil consumption speed and the time interval, and the current remaining oil quantity can be determined by combining the oil consumption and the initial remaining oil quantity.
Specifically, the determined remaining amount of oil may be displayed to the user. Possibly, the determined residual oil quantity can be displayed to a user through the meter, and the user can conveniently and visually judge the residual oil quantity. Possibly, the determined remaining oil amount may be played to the user through a device such as a speaker, or the remaining oil amount may be displayed on the touch screen when a touch instruction that the user does not want to listen to the remaining oil amount is received, as shown in fig. 4, which is an interface effect diagram for displaying the remaining oil amount provided in the embodiment of the present application. In fig. 4, it can be seen that the remaining power is displayed in the upper left corner of the interface in a percentage manner, a button with a prompt sound may be further disposed below the corresponding remaining power, and the user may touch the button with the prompt sound to make the speaker play the current remaining power. It should be noted that when the remaining oil amount is detected to be less than the preset threshold, the warning information can be played through the loudspeaker or the warning interface frame with the insufficient oil amount can be popped up on the touch screen to remind the user of refueling in time. Preferably, the preset threshold value is twenty percent of the total fuel tank.
In the embodiment of the application, the corresponding damping speed can be determined based on the current running speed of the vehicle, the current oil consumption speed of the vehicle can be obtained through calculation according to the set maximum limit value of the instantaneous oil consumption, the detected instantaneous oil consumption and the determined damping speed of the vehicle, and the current residual oil quantity of the vehicle can be further obtained through the oil consumption speed. The method is different from the method of directly determining the output residual oil quantity according to the liquid level in the vehicle oil tank, and the oil consumption speed of the vehicle in a certain time period or a preset time interval in the driving process is obtained through calculation, so that the residual oil quantity in the time period or the preset time interval can be obtained, and the stability of the residual oil quantity is ensured. Based on this embodiment can make the current residual oil volume that the vehicle shows more stable, the great condition of fluctuation can not appear, and then also can avoid the instrument to take place the jump phenomenon to bring more directly perceived, accurate oil volume judgement for the user.
As an embodiment of the present application, based on the above-mentioned oil amount calculation method, the present application proposes an oil amount output control method including:
acquiring a current running speed, and determining a damping speed based on the current running speed;

Specifically, after the remaining oil amount is determined according to step 201, step 202, and step 203, the remaining oil amount may be displayed to the user through a display manner such as a meter, a speaker, or a touch screen, so as to implement output control of the oil amount.

And step 504, when the residual oil quantity belongs to a preset interval, determining a preset first threshold value of the preset interval as a target oil quantity.
Specifically, the preset interval is an interval greater than a preset first threshold and smaller than a second threshold, and the preset first threshold is smaller than the preset second threshold. Wherein the preset interval may be set as a continuous interval of 10 liters, such as 0-10 liters, 10-20 liters, 20-30 liters. It is mainly explained here that the interval of the preset interval provided in the embodiments of the present application may not be limited to the above-mentioned 10 liters, and the present application does not limit this. Taking the preset interval of 20-30 liters as an example, the preset first threshold value is 20 liters, the preset second threshold value is 30 liters, and when the remaining oil amount is 26 liters, the preset interval is reached, the target oil amount can be determined to be 20 liters.
The oil quantity of the vehicle belongs to a continuous consumption state in the driving process, a controller of the vehicle can constantly receive oil consumption data and calculate the residual oil quantity, oil quantity values observed by users in real time are different, and the mode can influence the basic judgment of the users on the oil quantity. In this application embodiment, when the remaining oil amount is in a certain interval, the minimum value in the interval can be used as the target oil amount displayed to the user, and the oil amount displayed on the meter in the interval can be maintained at the minimum value, so that the meter is prevented from continuously descending and the judgment of the user on the oil amount is not affected.
And step 505, outputting the target oil quantity.
Specifically, after the target oil amount is determined according to the preset interval where the residual oil amount is located, the target oil amount can be displayed to the user through a display mode such as an instrument, a loudspeaker or a touch screen. Specifically, referring to fig. 6, a schematic diagram of the effect of outputting the oil amount provided by the embodiment of the present application may be understood as a schematic diagram of calculating the oil amount resistance for displaying the liquid level fluctuation in combination with the embodiment of the present application and corresponding to the output residual oil amount that falls in a stable gradient. The upper part shown in fig. 6 is a change diagram of the liquid level in the oil tank when the vehicle runs on an uphill road section or a downhill road section, and it is found that the fluctuation is too large, and the oil quantity cannot be output directly according to the liquid level. The lower half shown in fig. 6 is a current fuel consumption speed calculated according to the embodiment of the present application in combination with the current driving speed of the vehicle and the fuel consumption parameter within a preset time interval, and the remaining fuel amount is determined based on the current fuel consumption speed, and the preset interval corresponding to the remaining fuel amount is a continuous interval with an interval of 1 liter, such as 36-37 liters, 37-38 liters, 38-39 liters, and so on. Assuming that the remaining oil amount is determined to be in the 36-37 interval when the remaining oil amount is calculated to be 36.5 liters, the target oil amount is determined to be 36 liters based on this and 36 liters is output to be displayed to the user. It can be clearly seen that the oil quantity increase shown in fig. 6 can effectively avoid the phenomenon that the display instrument jumps when the vehicle runs on an uphill slope or a downhill slope, and can bring more accurate oil quantity judgment to a user.
In the embodiment of the application, the corresponding damping speed can be determined based on the current running speed of the vehicle, the current oil consumption speed of the vehicle can be obtained through calculation according to the set maximum limit value of the instantaneous oil consumption, the detected instantaneous oil consumption and the determined damping speed of the vehicle, and the current residual oil quantity of the vehicle can be further obtained through the oil consumption speed. The method is different from the method of directly determining the output residual oil quantity according to the liquid level in the oil tank of the vehicle, and the oil consumption speed of the vehicle in a certain time period or a preset time interval in the driving process is obtained through calculation, so that the residual oil quantity in the time period or the preset time interval can be obtained. Furthermore, when the residual oil quantity is detected to belong to the preset interval, the minimum value of the preset interval is used as the target oil quantity to be output to a user, the oil quantity displayed to the user when the residual oil quantity of the vehicle changes in a certain interval is a constant value, and the staged oil quantity consumption change is brought to the user, so that the stability of the oil quantity change is guaranteed, and the oil quantity judgment of the user can be more accurately performed.
