Description

Technical Field

[0001] The present invention relates to the technical field of vehicle fuel quantity calculation, and in particular to a vehicle fuel quantity display method, device, equipment and storage medium. Background Art

[0002] As vehicles become more and more intelligent, the requirements for data accuracy are also getting higher and higher. For example, if the instrument oil level display accuracy is 1%, and the sensor uses a segmented sensor, it is necessary to achieve high-precision display of the oil level signal from the software. The segmented oil level sensor is composed of multiple resistors. The resistance value increases nonlinearly from bottom to top in a step-by-step manner. There is a certain gap between the resistors. When the oil level float floats up and down between the two resistors, the resistance value remains unchanged. At this time, the oil level sensor signal collected by the control is also unchanged. The sensor resistance value increases in a step-by-step manner, and the signal collected by the controller also presents a step-by-step mutation. The sudden change of the sensor signal, coupled with the bumps on the road, will cause the oil level display value to jump, which in turn leads to inaccurate oil level display results.

[0003] Therefore, how to achieve accurate display of vehicle fuel level is a technical problem that urgently needs to be solved. Summary of the invention

[0039] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0040] Furthermore, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. Some of the blocks shown in the drawings are functional entities and do not necessarily correspond to physically or logically separate entities.

[0041] The embodiments of the present application provide a vehicle fuel level display method, device, equipment and storage medium, which implement filtering and smoothing of the fuel level signal through the average value of two different sampling rates, thereby achieving the purpose of high-precision and smooth display of fuel level changes.

[0042] In order to achieve the above technical effects, the general idea of ​​this application is as follows:

[0043] A method for displaying the fuel level of a vehicle, the method comprising the steps of:

[0044] S101: Based on a set first sampling period, an oil level signal during vehicle driving is collected, and an average value of the oil level signal is calculated in real time.

[0045] S102: Based on a set second sampling period, an average value of the oil quantity signal is obtained, and an average value of the average values ​​of the oil quantity signal is calculated in real time to smooth the oil quantity signal.

[0046] S103: Based on the smoothed fuel level signal, determine whether to display the current fuel level value of the vehicle.

[0047] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0048] Reference Figure 1 , Figure 1 FIG. 1 is a flow chart of a vehicle fuel level display method provided by the present invention, as shown in FIG. Figure 1 As shown, the method comprises the steps of:

[0049] Step S101: Based on a set first sampling period, the fuel level signal of the vehicle during driving is collected, and the average value of the fuel level signal is calculated in real time.

[0050] It needs to be explained that, based on the set first sampling period, the oil level signal of the vehicle during driving is collected, and before the real-time calculation of the average value of the oil level signal, it includes: judging the state of the vehicle during refueling, the state including the vehicle powered on state and the vehicle not powered on state; executing the corresponding display strategy according to the state of the vehicle during refueling.

[0051] It is understandable that the vehicle is generally refueled when it is stationary, and the oil level will change greatly before and after refueling. The software records the last sampling data before the vehicle is powered off, and calculates the difference between the data collected after powering on and the last sampling data before the vehicle is powered off. If the absolute value of the difference is greater than the maximum change threshold set by the software, and the vehicle is stationary, it is considered that the vehicle is refueling, and the first collected data after powering on is displayed as the current oil level value, otherwise it is displayed according to the oil level value before the vehicle is powered off.

[0052] Specifically, if the vehicle is not powered on during refueling, the fuel level signal en collected last time before power off is stored;

[0053] After the vehicle is powered on after refueling, the fuel level signal ex is collected, and the difference △e is calculated between the collected fuel level signal value and en;

[0054] The absolute value of △e is compared with the set judgment threshold △emax. When △e is greater than △emax, it is determined that the vehicle has been refueled and ex is sent as the display value. When △e is less than △emax, the fuel value after filtering before power off is sent. As display value;

[0055] If the vehicle is powered on during refueling, the fuel level signal ex is collected according to the set period, and when the difference △e between the fuel level signal ex collected according to the set period and the fuel level signal en collected last time before power off is greater than △emax, the fuel level display result is updated in real time according to the fuel level signal collected according to the set period;

[0056] If the difference △e between the oil level signal ex collected according to the set period and the oil level signal en collected for the last time before power-off is less than △emax, it is determined that the vehicle has not been refueled, and the oil level value before the last power-off is displayed.

[0057] Specifically, a first queue is created to store a plurality of oil quantity signal data;

[0058] Collecting a fuel level signal of the vehicle during the characterization process once at a first preset time interval, and storing the collected fuel level signal in the first queue;

[0059] The average values ​​of multiple oil quantity signals in the first queue are calculated to filter the oil level fluctuations, wherein the data in the first queue are updated according to the first-in-first-out principle, so that a new average value is generated at regular intervals.

[0060] For easy understanding, let's take an example. A queue A is created, which can hold N data. The software collects sensor data e every T1 seconds and puts it into the queue. The queue data is updated according to the first-in-first-out principle, and the real-time average ê is calculated: ê = (e1+e2+......en) / N. The arithmetic mean ê reflects the trend in the data set and can effectively filter out the ups and downs of the oil signal caused by road bumps.

[0061] Optionally, when the vehicle is driving on a bumpy road, the fuel in the fuel tank will fluctuate up and down, driving the float of the fuel level sensor to float up and down, resulting in the fuel level sensor signal value collected by the controller to be inaccurate, and the collected value is distributed above and below the actual value. Collect the fuel level signal multiple times, period T2, form a queue of length N, calculate the average value, and obtain a fuel level signal close to the actual value. Thereby achieving the filtering effect of the oil level fluctuation. The queue continuously updates the fuel level signal value in the queue according to the first-in-first-out principle, and generates a new average value every once in a while.

[0062] It can be understood that the oil level fluctuation can be filtered by the above-mentioned method of calculating the average value.

[0063] Step S102: Based on the set second sampling period, the average value of the oil level signal is obtained, and the average value of the average values ​​of the oil level signal is calculated in real time to smooth the oil level signal.

[0064] Specifically, a second queue is created to store a plurality of oil level signal data; a data is obtained from the first queue at every second preset time interval and put into the second queue, and the average value of the average values ​​of the oil level signals in the second queue is calculated in real time.

[0065] For easier understanding, let's take an example. When the oil level sensor jumps from one gear to another, the signal collected by the sensor shows an obvious mutation. The dynamic averaging algorithm is used here to process it.

[0066] A queue B is created, which can hold M data. Every T2 time interval, a piece of data is obtained and put into the queue. The queue data is updated according to the first-in-first-out principle, and the real-time arithmetic mean is calculated at intervals. Data update: [ê1,ê2,ê3......êm]T2 time later [ê2,ê3,ê4......êm+1]

[0067] Arithmetic mean

[0068] Specifically, fast filtering: collect oil level signals multiple times, period T2, form a queue of length N, calculate the average value, and obtain an oil level signal close to the actual value. This achieves the filtering effect of oil level fluctuations. Smoothing filtering: Generate an average oil level signal value from the fast filtering queue every T3 (much greater than T2) time, form a queue of length M, and calculate the average value. Because the sampling interval of the smoothing filter stage is relatively long, there may be two stages of oil level sensor values ​​in the array. As the running time increases, the tank liquid level slowly decreases, the number of small oil level values ​​in the queue accounts for an increasing proportion, and the average value of the entire array becomes smaller and smaller, thereby achieving filtering of sudden changes in the oil level signal and making the oil level display smoother.

[0069] Step S103: Based on the smoothed fuel level signal, determine whether to display the current fuel level value of the vehicle.

[0070] Specifically, if the current oil level signal after smoothing is The oil level signal after smoothing at the previous moment If the difference between the two is less than the set threshold, the current oil volume signal after smoothing is output. As the oil level real-time display result;

[0071] If the current oil level signal after smoothing The oil level signal after smoothing at the previous moment If the difference between them is greater than the set threshold, the smoothing operation will continue until the set threshold is met, and the result will be output and displayed.

[0072] After the oil level signal is smoothed, it includes:

[0073] Determine whether the oil quantity signal value after smoothing is much greater than the oil quantity signal value calculated after smoothing in the previous cycle;

[0074] If yes, the result after this smoothing process is discarded, and the fuel level signal value calculated after the previous smoothing process is used as the current fuel level display result. It can be understood that 1) when the vehicle turns, due to the centrifugal force, the fuel level is concentrated on one side of the fuel tank, making the fuel level signal value larger.

[0075] 2) The addition of a larger fuel level signal value causes the software to obtain a larger fuel level value after fast filtering and smoothing filtering. This is because the fuel level signal value at this time is larger than the value calculated in the previous cycle. Considering that the fuel level value gradually decreases during driving, the software will discard this larger value and continue to display the value of the previous state.

[0076] Reference Figure 2 , Figure 2 FIG. 1 is a schematic diagram of a vehicle fuel level display device provided by the present invention, such as Figure 2 As shown, the device comprises:

[0077] The calculation module 201 is used to collect the fuel level signal of the vehicle during driving based on a set first sampling period, and calculate the average value of the fuel level signal in real time.

[0078] The processing module 202 is used to obtain the average value of the oil quantity signal based on the set second sampling period, and calculate the average value of the average values ​​of the oil quantity signal in real time to smooth the oil quantity signal.

[0079] Display module 203: It is used to determine whether to display the current fuel level value of the vehicle based on the fuel level signal after smoothing.

[0080] Further, in a possible implementation manner, the processing module is further used to determine the state of the vehicle during refueling, wherein the state includes a vehicle powered-on state and a vehicle unpowered state;

[0081] According to the state of the vehicle during refueling, the corresponding display strategy is executed.

[0082] Furthermore, in a possible implementation manner, the processing module is further configured to store the fuel level signal en collected last time before power is turned off if the vehicle is not powered on during refueling;

[0083] After the vehicle is powered on after refueling, the fuel level signal ex is collected, and the difference △e is calculated between the collected fuel level signal value and en;

[0084] The absolute value of △e is compared with the set judgment threshold △emax. When △e is greater than △emax, it is determined that the vehicle has been refueled and ex is sent as the display value. When △e is less than △emax, the fuel value after filtering before power off is sent. As display value;

[0085] If the vehicle is powered on during refueling, the fuel level signal ex is collected according to the set period, and when the difference △e between the fuel level signal ex collected according to the set period and the fuel level signal en collected last time before power off is greater than △emax, the fuel level display result is updated in real time according to the fuel level signal collected according to the set period;

[0086] If the difference △e between the oil level signal ex collected according to the set period and the oil level signal en collected for the last time before power-off is less than △emax, it is determined that the vehicle has not been refueled, and the oil level value before the last power-off is displayed.

[0087] Furthermore, in a possible implementation manner, the processing module is further used to create a first queue to store a plurality of oil quantity signal data;

[0088] Collecting a fuel level signal of the vehicle during the characterization process once at a first preset time interval, and storing the collected fuel level signal in the first queue;

[0089] The average values ​​of multiple oil quantity signals in the first queue are calculated to filter the oil level fluctuations, wherein the data in the first queue are updated according to the first-in-first-out principle, so that a new average value is generated at regular intervals.

[0090] Furthermore, in a possible implementation manner, the display module is also used to display the current oil level signal after smoothing. The oil level signal after smoothing at the previous moment If the difference between the two is less than the set threshold, the current oil volume signal after smoothing is output. As the oil level real-time display result;

[0091] If the current oil level signal after smoothing The oil level signal after smoothing at the previous moment If the difference between them is greater than the set threshold, the smoothing operation will continue until the set threshold is met, and the result will be output and displayed.

[0092] Furthermore, in a possible implementation manner, the processing module is further used to determine whether the fuel quantity signal value after smoothing is much greater than the fuel quantity signal value calculated after smoothing in the previous cycle;

[0093] If so, the result after this smoothing process is discarded, and the oil quantity signal value calculated after the previous smoothing process is used as the current oil quantity display result.

[0094] Reference Figure 3 , Figure 3 The figure shows the oil quantity display processing flow chart provided by the present invention, as shown in FIG. Figure 3 As shown:

[0095] If the vehicle is powered on during refueling, the fuel level signal ex is collected according to the set period (T1), and when the difference △e between the fuel level signal ex collected according to the set period and the fuel level signal en collected for the last time before power off is greater than △emax, the fuel level display result (fuel level E=ex) is updated in real time according to the fuel level signal collected according to the set period.

[0096] If the difference △e between the fuel level signal ex collected according to the set period and the fuel level signal en collected last time before power off is less than △emax, it is determined that the vehicle has not been refueled, and the fuel level value before the last power off is displayed (fuel level where is the final displayed value after filtering).

[0097] Then determine whether the vehicle is started. If not, return to the step of collecting the fuel sensor signal ex, sampling period T1. If yes, collect the fuel sensor signal e, sampling period T2, and put the collected fuel signal into queue A to calculate the fuel level fluctuation filter:

[0098] ê=(e0+e1+...en-1+en) / N. Periodically obtain the average value of the oil volume signal ê, and put ê into queue B with a period of T3 to perform dynamic smoothing filtering: If the current oil level signal after smoothing The oil level signal after smoothing at the previous moment If the difference between the two is less than the set threshold, the current oil volume signal after smoothing is output. The result is displayed in real time as oil level.
