[0032] Embodiment 1

[0033] Figure 1 This is a flow chart of a method for observing the fuel level of a vehicle provided in the first embodiment of the present invention. This embodiment is applicable to the case of realizing high-precision fuel level observation. The method can be executed by a vehicle fuel level observation device. The vehicle fuel level observation device can be implemented in the form of hardware and / or software. The vehicle fuel level observation device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0034] S110, determining the current fuel level collection data and the last fuel level observation data of the target vehicle.

[0035] Among them, the target vehicle may refer to a vehicle that needs to display the fuel level. The fuel level collection data may refer to the fuel level data determined based on data collection, and the fuel level observation data may refer to the fuel level data determined based on data estimation (calculation). Among them, the fuel level data can be used to characterize the amount of fuel remaining in the target vehicle's fuel tank. For example, the parameters corresponding to the fuel level data may be the fuel level height, the percentage of the fuel level height (the percentage of the fuel level height to the tank height) or the fuel volume, etc. The current fuel level collection data may refer to the fuel level collection data corresponding to the current detection moment. The previous fuel level observation data may refer to the fuel level display data corresponding to the previous detection moment.

[0036] In this embodiment, the fuel level sensor installed on the target vehicle can collect the fuel level sensor value based on the preset period, and convert the collected fuel level sensor value into a quantity that can represent the actual physical meaning, such as the percentage of the fuel level height or the absolute value of the fuel level height, as the fuel level collection data at different detection times, which is used to characterize the amount of fuel remaining in the target vehicle's fuel tank at different detection times. Among them, the preset period can be determined according to the speed of the change of the tank level. The faster the level changes, the shorter the preset period. Exemplarily, the preset period can be set to a value between 10ms-1s. For example, based on the above method, the fuel level sensor value corresponding to the current detection time is obtained and converted into the fuel level height, and the current fuel level collection data of the target vehicle can be obtained. The previous fuel level observation data can be determined by reading the fuel level display data of the target vehicle at the previous detection time.

[0037] It should be noted that the parameters corresponding to the fuel level data need to be determined according to different vehicle models, that is, the target vehicle is set to use which parameters to display the fuel level. After the fuel level sensor value of the target vehicle is collected, it needs to be converted into which parameters for display. For example, this solution adopts the method of analog acquisition of output voltage, the voltage range is 0-5V, and the corresponding fuel level percentage is 0-100%.

[0038] In addition, other fuel level sensors can be used to determine the fuel level collection data of the target vehicle at different detection times, or to obtain the instantaneous fuel consumption of the target vehicle at different detection times, and calculate the fuel level collection data of the target vehicle at different detection times based on the instantaneous fuel consumption.

[0039] S120, determining a last fuel level acquisition error and a last fuel level observation error of the target vehicle.

[0040] The fuel level acquisition error is the acquisition error of the fuel level acquisition data, and the fuel level observation error is the estimation error of the fuel level observation data. The last fuel level acquisition error and the last fuel level observation error may refer to the fuel level acquisition error and the fuel level observation error corresponding to the last detection moment, respectively.

[0041] In this embodiment, if the fuel level collection data is determined by a sensor, the sensor's detection accuracy, such as ±10%, can be obtained through the sensor specification as the fuel level collection error; if the fuel level collection data is determined by instantaneous fuel consumption, the collection error of instantaneous fuel consumption can be used as the fuel level collection error. It should be noted that the fuel level collection errors corresponding to different detection moments are all the same fixed values. Exemplarily, the fuel level collection error and the fuel level observation error can be presented in the form of absolute values, or in the form of relative values ​​such as percentages or decimals, which is not limited in this embodiment.

[0042] In this embodiment, optionally, the method further includes: using the initial fuel level acquisition error of the target vehicle as the initial fuel level observation error of the target vehicle. The initial fuel level acquisition error and the initial fuel level observation error may refer to the fuel level acquisition error and the fuel level observation error at the initial detection time, respectively. For example, assuming that the initial time is time 0, and the fuel level acquisition error at time k is denoted by E mea (k) represents the fuel level observation error at time k, and E est (k) indicates that the initial fuel level observation error can be initialized as the initial fuel level acquisition error, that is, let E est (0) = E mea (0).

[0043] Through such a setting, the present scheme can initialize the initial fuel level observation error in a simple and quick manner.

[0044] S130, determining a current fuel level observation weight according to a previous fuel level acquisition error and a previous fuel level observation error.

[0045] The fuel level observation weight is used to characterize the importance of the fuel level observation error to the fuel level observation data. The current fuel level observation weight may refer to the fuel level observation weight corresponding to the current detection moment.

[0046] In this embodiment, after determining the last fuel level acquisition error and the last fuel level observation error, the current fuel level observation weight can be determined according to the last fuel level acquisition error and the last fuel level observation error. Optionally, determining the current fuel level observation weight according to the last fuel level acquisition error and the last fuel level observation error includes: determining the last fuel level total error of the target vehicle according to the sum of the last fuel level acquisition error and the last fuel level observation error; determining the current fuel level observation weight according to the ratio of the last fuel level observation error to the last fuel level total error.

[0047] The last total error of the fuel level may refer to the total error of the fuel level corresponding to the last detection moment. For example, the following formula may be used to calculate the current fuel level observation weight:

[0048]

[0049] Among them, K(k) represents the current (time k) fuel level observation weight, E mea (k-1) represents the fuel level acquisition error at the previous (k-1 moment), E est (k-1) represents the fuel level observation error at the previous (k-1 moment), E mea (k-1)+E est (k-1) represents the total error of the fuel level at the previous (k-1 moment).

[0050] It should be noted that, from the above formula, it can be seen that the greater the current fuel level observation weight, the higher the proportion of the previous fuel level observation error in the previous fuel level total error, that is, the higher the importance of the previous fuel level observation error to the current fuel level observation data. Among them, the current fuel level observation data may refer to the fuel level observation data corresponding to the current detection moment.

[0051] S140, determining the current fuel level observation data of the target vehicle according to the current fuel level observation weight, the current fuel level collection data and the previous fuel level observation data.

[0052] In this embodiment, after determining the current fuel level observation weight, the current fuel level observation data of the target vehicle can be determined according to the current fuel level observation weight, the current fuel level collection data and the previous fuel level observation data. Optionally, determining the current fuel level observation data of the target vehicle according to the current fuel level observation weight, the current fuel level collection data and the previous fuel level observation data includes: subtracting the current fuel level collection data from the previous fuel level observation data to obtain the first reference data; multiplying the current fuel level observation weight by the first reference data to obtain the second reference data; and adding the previous fuel level observation data to the second reference data to obtain the current fuel level observation data.

[0053] For example, taking the absolute value of the fuel level height as the fuel level data, the following formula can be used to determine the current fuel level observation data:

[0054] H est (k) = H est (k-1)+K(k)*(H mea (k)-H est (k-1));

[0055] Among them, H est (k) represents the current (time k) fuel level observation height, H mea (k) represents the current (time k) fuel level collection height, H est (k-1) represents the fuel level observation height at the previous (k-1 moment), K(k) represents the fuel level observation weight at the current (k moment), H mea (k)-H est (k-1) represents the first reference data, K(k)*(H mea (k)-H est (k-1)) represents the second reference data.

[0056] It should be noted that the calculation and display cycle of the fuel level observation data needs to be consistent with the collection cycle of the fuel level collection data. After determining the current fuel level observation data of the target vehicle, the current fuel level observation data can be displayed to the driver through a display unit on the target vehicle, such as an instrument, a vehicle computer or other display device. Compared with the sensor collection data, this observation data has a higher accuracy, so that the driver can know the current fuel level of the target vehicle in advance. The mileage can also be further calculated through the current fuel level observation data, which helps to plan the trip reasonably.

[0057] The technical solution of the embodiment of the present invention first determines the current fuel level collection data and the last fuel level observation data of the target vehicle; and determines the last fuel level collection error and the last fuel level observation error of the target vehicle; then determines the current fuel level observation weight according to the last fuel level collection error and the last fuel level observation error; and then determines the current fuel level observation data of the target vehicle according to the current fuel level observation weight, the current fuel level collection data and the last fuel level observation data. This technical solution, in response to the problem of insufficient detection accuracy of existing liquid level sensors, realizes high-precision fuel level observation based on the fuel level observation weight, can effectively improve the display accuracy of the fuel level without increasing hardware costs, helps to improve the driver's driving experience, and has high practical value and good application prospects.

[0058] In this embodiment, optionally, the method further includes: using the initial fuel level acquisition data of the target vehicle as the initial fuel level observation data of the target vehicle.

[0059] For example, taking the absolute value of the fuel level height as the fuel level data, assuming that the initial time is time 0, the fuel level collection height at time k is H mea (k) represents the fuel level observation height at time k, and H est (k) indicates that the initial fuel level observation height can be initialized as the initial fuel level acquisition height, that is, let H est(0) = H mea (0).

[0060] Through such a setting, the present scheme can initialize the initial fuel level observation height in a simple and quick manner.

[0061] Embodiment 2

[0062] Figure 2 This is a flow chart of a method for observing the fuel level of a vehicle provided in the second embodiment of the present invention. This embodiment is optimized based on the above embodiment.

[0063] like Figure 2 As shown, the method of this embodiment specifically includes the following steps:

[0064] S210, determining the current fuel level collection data and the last fuel level observation data of the target vehicle.

[0065] S220, determining a last fuel level acquisition error and a last fuel level observation error of the target vehicle.

[0066] S230, determining a current fuel level observation weight according to a previous fuel level acquisition error and a previous fuel level observation error.

[0067] S240, determining the current fuel level observation data of the target vehicle according to the current fuel level observation weight, the current fuel level collection data and the previous fuel level observation data.

[0068] Among them, the specific implementation method of S210-S240 can refer to the detailed description of S110-S140, which will not be repeated here.

[0069] S250, determining a current fuel level observation error of the target vehicle according to a current fuel level observation weight and a previous fuel level observation error.

[0070] The current fuel level observation error may refer to the fuel level observation error corresponding to the current detection moment. Optionally, the current fuel level observation error of the target vehicle is determined according to the current fuel level observation weight and the previous fuel level observation error, including: multiplying the current fuel level observation weight by the previous fuel level observation error to obtain a reference observation error; subtracting the previous fuel level observation error from the reference observation error to obtain the current fuel level observation error.

[0071] For example, the current fuel level observation error may be determined using the following formula:

[0072] E est (k)=(1-K(k))*E est (k-1);

[0073] Among them, E est (k) represents the current (time k) fuel level observation error, K(k) represents the current (time k) fuel level observation weight, E est (k-1) represents the fuel level observation error at the last (k-1 moment), K(k)*E est (k-1) represents the reference observation error.

[0074] S260, determining a current fuel level collection error and next fuel level collection data of the target vehicle.

[0075] Among them, the current fuel level collection error may refer to the fuel level collection error corresponding to the current detection moment, and the next fuel level collection data may refer to the fuel level collection data corresponding to the next detection moment. Specifically, it can be determined by referring to the relevant description of the previous fuel level collection error and the current fuel level collection data in the above-mentioned embodiment 1.

[0076] S270, determining the next fuel level observation weight according to the current fuel level acquisition error and the current fuel level observation error.

[0077] Among them, the next fuel level observation weight may refer to the fuel level observation weight corresponding to the next detection moment. Optionally, the next fuel level observation weight is determined according to the current fuel level acquisition error and the current fuel level observation error, including: determining the current total fuel level error of the target vehicle according to the sum of the current fuel level acquisition error and the current fuel level observation error; determining the next fuel level observation weight according to the ratio of the current fuel level observation error to the current total fuel level error.

[0078] Among them, the current total fuel level error may refer to the total fuel level error corresponding to the current detection moment. The current total fuel level error and the next fuel level observation weight may be determined by referring to the relevant descriptions of the previous total fuel level error and the current fuel level observation weight in Example 1. Thus, the next fuel level observation weight may be quickly determined based on the current fuel level acquisition error and the current fuel level observation error.

[0079] S280, determining the next fuel level observation data of the target vehicle according to the next fuel level observation weight, the next fuel level collection data and the current fuel level observation data.

[0080] Among them, the next fuel level observation data may refer to the fuel level observation data corresponding to the next detection moment. Optionally, according to the next fuel level observation weight, the next fuel level collection data and the current fuel level observation data, the next fuel level observation data of the target vehicle is determined, including: subtracting the next fuel level collection data from the current fuel level observation data to obtain the first target data; multiplying the next fuel level observation weight by the first target data to obtain the second target data; adding the current fuel level observation data to the second target data to obtain the next fuel level observation data.

[0081] The method for determining the next fuel level observation data may refer to the description of the current fuel level observation data in the first embodiment. Thus, the next fuel level observation data of the target vehicle may be quickly determined based on the next fuel level observation weight, the next fuel level collection data, and the current fuel level observation data.

[0082] Figure 3 This is a schematic diagram of a method for observing the fuel level of a vehicle provided by Embodiment 2 of the present invention. Figure 3 As shown in the figure, assuming that the current time is time k, taking the fuel level height value as the fuel level data as an example, when the target vehicle is started (powered on, i.e., KEY ON), the fuel level observation error E is initialized first. est (0) = E mea (0) and fuel level observation data H est (0) = H mea (0). Then collect the fuel level sensor value at time k and convert it into the fuel level height value H mea (k). Next, calculate the fuel level observation weight K(k) at time k, the fuel level observation height value H at time k, and est (k) and the fuel level observation error E at time k est (k), and the display unit est (k) is displayed. Then determine whether the target vehicle is stopped (i.e., KEY OFF). If so, end the calculation process. Otherwise, set k = k + 1, that is, the output E est (k) and H est (k) is used as the input for the next cycle, so that the fuel level observation height values ​​at different detection times can be continuously calculated. This solution automatically adjusts the fuel level observation weight according to the fuel level observation error and the fuel level acquisition error to ensure that the error of the final output fuel level observation data is minimized.

[0083] Figure 4 This is a schematic diagram of a vehicle fuel level observation system provided by Embodiment 2 of the present invention. Figure 4As shown, the system includes a collection unit, a calculation processing unit and a display unit. The collection unit can be used to collect the fuel level sensor values ​​at different detection times; the calculation processing unit can be used to convert the collected fuel level sensor values ​​into fuel level collection data, and is responsible for calculating the fuel level observation data at different detection times; the display unit can be used to display the calculated fuel level observation data to the driver.

This technical solution can automatically adjust the fuel level observation weight according to the fuel level observation error and the fuel level collection error to ensure that the error of the fuel level observation data finally outputted is minimized, which helps to improve the display accuracy of the fuel level observation data.
