[0002] With the rapid development of my country's social economy and the improvement of people's living standards, the number of private cars has increased significantly and has become one of the main means of transportation. At present, the cars on the market are mainly traditional fuel vehicles, which use fuel combustion to provide power for the vehicles. Therefore, the requirements for accurate display of vehicle fuel level are also increasing. At present, the main methods for displaying vehicle fuel level are motor pointer drive, segment distribution, and LCD display.

[0003] Currently, the change in fuel level in a vehicle's fuel tank is usually uniform or linear as the vehicle moves. However, in reality, factors such as uncertain road conditions, refueling, and fuel leaks can cause changes in the actual fuel level reading. If the actual fuel level reading is used as the basis for the fuel level display, it may result in an incorrect fuel level reading, leading to a low accuracy rate for the vehicle's fuel level display.

[0082] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0083] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0084] Currently, fuel level gauges in fuel tanks typically consist of a sliding rheostat and a float. Due to the diverse driving conditions, such as sudden braking, slopes, and bumpy roads, the float on the fuel surface can easily move with the fuel level, causing the sliding rheostat to fluctuate and further affecting the fuel level reading. Factors such as refueling and fuel leaks can also cause changes in the fuel level reading. The purpose of a vehicle's fuel gauge is to display the remaining fuel level in the tank in real time, helping users determine when to refuel and calculate driving range. Inaccurate fuel gauge readings or frequent fluctuations in the fuel gauge needle can mislead users, cause complaints, and even lead to functional safety issues, ultimately impacting vehicle sales and brand reputation. Therefore, improving the accuracy of fuel level displays is crucial.

[0085] This application provides a method for displaying vehicle fuel level. In the first embodiment of this method, refer to... Figure 1 The vehicle fuel level display method includes:

[0086] Step S10: If the target vehicle is detected to be powered on, the previous fuel reference value of the target vehicle is obtained, and the current fuel sampling value of the target vehicle is collected.

[0087] Step S20: Based on the current fuel sampling value and the previous fuel reference value, perform fuel behavior detection on the target vehicle to obtain the corresponding fuel behavior detection result;

[0088] Step S30: Based on the fuel behavior detection results, assign a value to the current fuel quantity of the target vehicle to obtain the current fuel display value;

[0089] Step S40: Based on the current fuel display value, control the target vehicle to display the fuel quantity.

[0090] In this embodiment, it should be noted that the previous fuel reference value is used to record the fuel reference value before the fuel gauge is powered off, so that when the target vehicle is powered on, this value can be used as a display data support to accurately display the current real fuel value; the current fuel sampling value refers to the current fuel value of the target vehicle collected.

[0091] As an example, steps S10 to S40 include: (refer to...) Figure 2The diagram illustrates the fuel level display process upon power-on. When a target vehicle is detected to be powered on, the system reads the previous fuel reference value and the previous fuel display value stored in the target vehicle's memory database, and samples the current fuel level to obtain the target vehicle's current fuel sample value. Based on the current fuel sample value and the previous fuel reference value, the system performs fuel behavior detection on the target vehicle, specifically detecting whether the target vehicle has refueled or leaked fuel during the power-off process, obtaining the corresponding fuel behavior detection result. The fuel behavior may include refueling or leaking fuel. The fuel behavior detection result characterizes whether the target vehicle has triggered fuel behavior. The condition for triggering fuel behavior is that there is a first difference between the current fuel sample value and the current fuel reference value, and this first difference persists for a stable period of time. The current fuel reference value is based on the target vehicle's... The vehicle speed attribute and power attribute are obtained by updating the previous fuel reference value. The vehicle speed attribute is used to indicate whether the target vehicle's speed is zero, and the power attribute is used to indicate the overall power status of the target vehicle. If the fuel behavior detection result is a triggered fuel behavior, the fuel change amplitude corresponding to the triggered fuel behavior is obtained. It is then checked whether the first difference is greater than or equal to the fuel change amplitude. If it is greater than or equal to the fuel change amplitude, the current fuel reference value is used as the current fuel display value. The fuel change amplitude is set based on the triggering of the fuel behavior, and in this embodiment, it can be set to 0.3L. If it is less than the fuel change amplitude, the previous fuel display value is used as the current fuel display value. Based on the current fuel display value, the target vehicle is controlled to display the fuel quantity.

[0092] As a preferred example, considering that the target vehicle may be powered on for the first time, a step to determine whether the previous fuel reference value was zero can be added to this embodiment. If the previous fuel reference value was zero, it means that the target vehicle is powered on for the first time, and the current fuel sampling value is directly assigned to the current display value. If the previous fuel reference value was not zero, it means that the target vehicle is not powered on for the first time, and subsequent fuel behavior detection is performed.

[0093] In this embodiment, based on the characteristic of the vehicle's fuel tank float floating according to the fuel level, to ensure that the fuel level displayed on the fuel gauge when the target vehicle is powered on remains consistent with that when it is powered off, thus avoiding user confusion, a "previous fuel level display value" attribute is defined. This allows users to more clearly observe the fuel level changes of the target vehicle, improving the user experience. In addition, the defined "previous fuel reference value" attribute provides data support for the current fuel level display. Fuel behavior detection can detect whether the target vehicle has refueled or leaked fuel when it is powered off, thereby further improving the accuracy of the vehicle's fuel level display.

[0094] The step of detecting fuel behavior of the target vehicle based on the current fuel sampling value and the previous fuel reference value to obtain the corresponding fuel behavior detection result includes:

[0095] Step S21: Update the previous fuel reference value based on the vehicle speed attribute and power attribute of the target vehicle to obtain the current fuel reference value of the target vehicle.

[0096] Step S22: Based on the current fuel sampling value and the current fuel reference value, perform fuel behavior detection on the target vehicle to obtain the fuel behavior detection result.

[0097] As an example, steps S21 to S22 include: based on the vehicle speed attribute, detecting whether the target vehicle's speed is zero to obtain the target vehicle's current speed reference value; based on the power attribute, detecting whether the target vehicle's overall power status is on to obtain the target vehicle's current power reference value; updating the previous fuel reference value based on the current vehicle speed reference value and the current power reference value to obtain the target vehicle's current fuel reference value; and detecting whether the target vehicle triggers fuel behavior based on the current fuel sampling value and the current fuel reference value to obtain the fuel behavior detection result.

[0098] In this embodiment, vehicle speed and power attributes are introduced to simulate the operation of the target vehicle in a relatively realistic manner, thereby improving the credibility and accuracy of the current fuel reference value and further improving the accuracy of the vehicle fuel level display.

[0099] The step of updating the previous fuel reference value based on the target vehicle's speed and power attributes to obtain the target vehicle's current fuel reference value includes:

[0100] Step S211: Based on the vehicle speed attribute, perform illegal speed detection and speed timeout detection on the current speed of the target vehicle to obtain the corresponding illegal speed detection result and speed timeout detection result.

[0101] Step S212: Based on the illegal speed detection result, the speed timeout detection result, and the current fuel sampling value, assign a value to the current speed of the target vehicle to obtain a current speed reference value;

[0102] Step S213: Based on the power attributes, perform power illegality detection and power timeout detection on the current power of the target vehicle to obtain the corresponding power illegality detection results and power timeout detection results;

[0103] Step S214: Based on the power illegal detection result, the power timeout detection result, and the current fuel sampling value, assign a value to the current power of the target vehicle to obtain the current power reference value;

[0104] Step S215: Perform reference value illegality detection on the current vehicle speed reference value and the current power supply reference value to obtain the reference value illegality detection result;

[0105] Step S216: Based on the illegal detection result of the reference value, update the fuel reference value of the target vehicle to obtain the current fuel reference value.

[0106] In this embodiment, it should be noted that the illegal speed detection result is used to characterize whether the speed reference value stored in the target vehicle has been assigned a value; the speed timeout detection result is used to characterize the timeout time related to the current speed of the target vehicle, which corresponds to a preset speed timing threshold, such as a preset time value of 5 seconds. If the speed timing is greater than or equal to 5 seconds, it is determined to be a timeout; the illegal power supply detection result is used to characterize whether the power supply reference value stored in the target vehicle has been assigned a value; the power supply timeout detection result has the same definition as the speed timeout detection result, and will not be described again; in this embodiment, the calculation order of the current speed reference value and the current power supply reference value can be set by the user, and is not limited to calculating the speed reference value first and then the power supply reference value in this embodiment.

[0107] As an example, steps S211 to S216 include: (refer to...) Figure 3 The flowchart illustrates the process. Based on the vehicle speed attribute, it determines whether the target vehicle has stopped. If it hasn't stopped, it means the target vehicle is currently moving, so the speed timer is set to zero, and the speed reference value is set to an invalid value. If it has stopped, an invalid speed detection is performed, which checks whether the speed reference value stored in the memory database is invalid. If the speed reference value stored in the memory database is invalid, a speed timeout detection is further performed, which checks whether the speed timer is greater than or equal to a preset speed timer threshold. If it is not greater than or equal to the preset speed timer threshold, it means the speed change duration is short, and the process ends. If it is greater than or equal to the preset speed timer threshold, meaning the speed is both invalid and has timed out, an invalid detection is performed on the power reference value stored in the memory database. If the power reference value stored in the memory database is not invalid, it is directly assigned to the current speed reference value. If the power reference value stored in the memory database is invalid, sampling is performed, and the current fuel sampling value is assigned to the current speed reference value. Similarly, the process can be referred to... Figure 4 The flowchart illustrates that the process for assigning the current power supply reference value is the same as the process for assigning the current vehicle speed reference value, and will not be repeated here; refer to... Figure 5After obtaining the current vehicle speed reference value and the current power reference value, in order to further ensure the accuracy of the subsequent current fuel reference value, an illegality check can be performed on the current vehicle speed reference value and the current power reference value again. First, the current vehicle speed reference value can be assigned to the current fuel reference value. Then, it can be checked whether the current fuel reference value is an illegal value. If the current fuel reference value is an illegal value, it means that the current vehicle speed reference value has been assigned. Then, it can be checked whether the current power reference value is an illegal value. If the current power reference value is not an illegal value, then the current power reference value can be assigned to the current fuel reference value.

[0108] In this embodiment, by utilizing illegal detection and timeout detection techniques, the reliability and accuracy of the current vehicle speed reference value and the current power reference value are improved, thereby increasing the credibility and accuracy of the subsequent current fuel reference value, and ultimately improving the accuracy of the vehicle fuel level display.

[0109] The step of detecting fuel behavior of the target vehicle based on the current fuel sampling value and the current fuel reference value, and obtaining the fuel behavior detection result, includes:

[0110] Step S221: Detect whether the first difference between the current fuel sample value and the current fuel reference value is greater than or equal to a preset first difference threshold.

[0111] Step S222: If the difference is greater than or equal to the preset first difference threshold, then detect whether the duration of the first difference is greater than or equal to the preset first duration threshold.

[0112] Step S223: If the result is greater than or equal to the preset first duration threshold, then the fuel behavior detection result is determined to be a triggered fuel behavior.

[0113] As an example, steps S221 to S223 include: (refer to...) Figure 6 First, it detects whether the first difference between the current fuel sample value and the current fuel reference value is greater than or equal to a preset first difference threshold x, where the preset first difference threshold is a standard value for the difference between the current fuel sample value and the current fuel reference value. If it is greater than or equal to the preset first difference threshold, it further detects whether the duration of the first difference is greater than or equal to a preset first duration threshold t, where the preset first duration threshold is a standard value for the duration of the first difference. If it is greater than or equal to the preset first duration threshold, the fuel behavior detection result is determined to be a triggered fuel behavior.

[0114] In this embodiment, the target vehicle can be determined to have triggered fuel behavior only when both the first difference and the duration of the first difference meet the conditions simultaneously, thus doubly ensuring the accuracy and reliability of the fuel behavior detection results.

[0115] The step of assigning a value to the current fuel level of the target vehicle based on the fuel behavior detection result to obtain the current fuel display value includes:

[0116] Step S31: If the fuel behavior detection result is a triggered fuel behavior, then query the corresponding fuel change magnitude.

[0117] Step S32: Detect whether the first difference is greater than or equal to the fuel change amplitude;

[0118] Step S33: If the change in fuel amount is greater than or equal to the change in fuel amount, then the current fuel reference value is used as the current fuel display value.

[0119] As an example, steps S31 to S33 include: if the fuel behavior detection result is a triggered fuel behavior, then query the corresponding fuel change amplitude; detect whether the first difference is greater than or equal to the fuel change amplitude; if it is greater than or equal to the fuel change amplitude, then use the current fuel reference value as the current fuel display value; if it is less than the fuel change amplitude, then it is necessary to further detect whether the duration of the first difference is greater than or equal to a preset second duration threshold.

[0120] The step of using the current fuel reference value as the current fuel display value further includes:

[0121] Step S34: If it is less than the fuel change range, then detect whether the duration of the first difference is greater than or equal to a preset second duration threshold.

[0122] Step S35: If the change in fuel quantity is greater than or equal to a preset second time threshold, then stop querying the change in fuel quantity.

[0123] As an example, steps S34 to S35 include: if the first difference is less than the fuel change amplitude, then detecting whether the duration of the first difference is greater than or equal to a preset second duration threshold, wherein the preset second duration threshold is used to characterize the duration standard value of the fuel behavior; if it is greater than or equal to the preset second duration threshold, it indicates that the fuel behavior of the target vehicle has lasted for a stable period of time, meeting the stopping condition, and then stopping the query of the fuel change amplitude.

[0124] In this embodiment, by performing difference detection and duration detection again on the target vehicle that triggered the fuel behavior, the current fuel display value of the target vehicle is obtained, thereby improving the accuracy of the current fuel display value.

[0125] The vehicle fuel level display method further includes:

[0126] Step A10: If the target vehicle is detected to be powered off, then obtain the previous fuel display value and the previous fuel reference value of the target vehicle.

[0127] Step A20: Detect whether the difference between the previous fuel display value and the current fuel display value is greater than or equal to a preset second difference threshold.

[0128] Step A30: If the value is greater than or equal to the preset second difference threshold, then the previous fuel display value is assigned to the current fuel display value.

[0129] Step A40: Detect whether the difference between the previous fuel reference value and the current fuel reference value is greater than or equal to a preset third difference threshold.

[0130] Step A50: If the value is greater than or equal to a preset third gap threshold, then update the previous fuel reference value to the current fuel reference value, and save the current fuel display value and the current fuel reference value.

[0131] In this embodiment, it should be noted that when the target vehicle is powered off, the "previous display value" and "previous reference value" are updated and saved. These are used to display the fuel quantity when the target vehicle is powered on again, as well as to record data on refueling and leakage during the synchronous power-off process after power-on.

[0132] As an example, steps A10 to A50 include: (refer to...) Figure 7 The flowchart illustrates the process as follows: If the target vehicle is detected to be powered off, the previous fuel consumption display value and the previous fuel consumption reference value of the target vehicle are obtained; the difference between the previous fuel consumption display value and the current fuel consumption display value is checked to see if it is greater than or equal to a preset second difference threshold, wherein the preset second difference threshold is used to characterize the standard difference value between the previous fuel consumption display value and the current fuel consumption display value; if it is greater than or equal to the preset second difference threshold, the previous fuel consumption display value is assigned to the current fuel consumption display value; the difference between the previous fuel consumption reference value and the current fuel consumption reference value is checked to see if it is greater than or equal to a preset third difference threshold, wherein the preset third difference threshold is used to characterize the standard difference value between the previous fuel consumption reference value and the current fuel consumption reference value; if it is greater than or equal to the preset third difference threshold, the previous fuel consumption reference value is updated to the current fuel consumption reference value, and the current fuel consumption display value and the current fuel consumption reference value are saved for displaying the fuel quantity the next time the target vehicle is powered on.

[0133] In this embodiment, the power-off process of the target vehicle is considered. In order to have data to rely on when the target vehicle is powered on again, the current fuel display value and the current fuel reference value are updated and saved during the power-off process, thereby improving the accuracy of the fuel quantity display when the target vehicle is powered on again.

[0134] This embodiment provides a method, device, equipment, and readable storage medium for displaying vehicle fuel level. Compared with the prior art, this embodiment first detects that the target vehicle is powered on, then obtains the previous fuel reference value of the target vehicle and collects the current fuel sampling value of the target vehicle; based on the current fuel sampling value and the previous fuel reference value, fuel behavior detection is performed on the target vehicle to obtain the corresponding fuel behavior detection result; based on the fuel behavior detection result, the current fuel level of the target vehicle is assigned a value to obtain the current fuel display value; based on the current fuel display value, the target vehicle is controlled to display the fuel level. This application introduces the attribute of a fuel reference value and performs fuel behavior detection on the target vehicle during the fuel level display process to detect whether the vehicle has refueled or leaked fuel, thereby calculating the current fuel display value based on the fuel behavior detection result. Compared with the current method that directly uses the actual fuel sampling value as the basis for fuel level display, this application considers the impact of vehicle refueling and fuel leakage on fuel level display, and the added fuel reference value serves as a data support for fuel level display, so that the fuel gauge can accurately display the current real fuel level, thus improving the accuracy of vehicle fuel level display.
