[0113] Example 1: In one embodiment, the following further illustrates the intelligent instrument fuel level display based on multi-source information fusion and dynamic regulation:
[0114] 1. Multi-source data collection
[0115] A fuel level sensor, pressure sensor, temperature sensor, and flow sensor are deployed inside the fuel tank. An inductive switch is installed at the fuel tank cap, and a conversion resistor is connected to the fuel pump float. The fuel level sensor collects real-time fuel level data, the pressure sensor monitors changes in tank pressure, the temperature sensor obtains fuel temperature, the flow sensor detects fuel inflow and outflow, the inductive switch provides feedback on the open / close status of the fuel tank cap, and the conversion resistor outputs a corresponding resistance value as the position of the fuel pump float changes. Simultaneously, the vehicle's electronic control unit collects driving data such as vehicle speed, engine speed, mileage, driving mode, fuel injection volume, and ignition status. An inertial measurement unit collects vehicle attitude data such as tilt angle and acceleration, and a communication unit acquires vehicle geographic location information and real-time weather data.
[0116] 2. Data fusion processing
[0117] All collected data is transmitted to the data processing module, where a Kalman filter algorithm is used to remove noise. The fuel level sensor's measurement is corrected using the pump float's conversion resistance data, and the fuel level data is recalibrated based on fuel temperature and pressure. A multidimensional fuel level calculation model is constructed, integrating vehicle driving, attitude, geographic location, and weather data to improve accuracy.
[0118] Multi-dimensional fuel quantity calculation model optimization: Building on the existing multi-dimensional fuel quantity calculation model, additional influencing factors are introduced. Vehicle load is taken into account, and load information is obtained through sensors in the vehicle's suspension system. Increased vehicle load leads to increased fuel consumption. Furthermore, real-time traffic congestion information (available through the communication unit) is combined to more accurately model fuel consumption under different levels of congestion. For example, in severely congested conditions, in addition to considering engine idling time and the number of starts and stops, the fuel consumption coefficient is dynamically adjusted based on the duration of congestion, making the fuel quantity calculation more accurate to actual conditions.
[0119] 3. Oil resistance strategy
[0120] A mapping table is established between the pump float's conversion resistance and fuel level. The data processing module monitors resistance changes in real time, obtains initial fuel level data through table lookup, and performs weighted fusion calculations based on data from other sensors. Dynamically adjust the mapping table parameters based on changes in the vehicle's ambient temperature and operating conditions to ensure accurate fuel level calculations under varying conditions.
[0121] 4. Vehicle start-up fuel reduction strategy
[0122] At the moment the vehicle starts, the data processing module builds a fuel consumption prediction model for the start-up phase based on parameters such as engine model, fuel injection volume at startup, and idle speed, combined with historical startup fuel consumption data. Initially, the fuel level display is updated at a lower frequency to avoid display anomalies caused by data fluctuations at startup. As the vehicle completes startup and enters stable operation, the fuel level display update frequency is gradually increased to a normal level, and the displayed value is adjusted in real time based on actual fuel consumption.
[0123] Optimization of the startup prediction model: The existing startup fuel consumption prediction model now takes the engine's thermal state into account. This information is obtained through the engine coolant temperature sensor, as the engine's fuel consumption characteristics differ during cold and hot starts. During a cold start, the engine requires more fuel to reach normal operating temperature, so the fuel consumption coefficient in the prediction model is appropriately increased. During a hot start, the fuel consumption coefficient is reduced, resulting in a more accurate fuel level display during startup.
[0124] 5. Fuel Level Display under Different Operating Conditions - Normal Driving Conditions: Utilizing a fuel consumption prediction model to calculate real-time fuel consumption, combining vehicle speed, engine speed, road conditions, weather, and other data, the instrument panel displays fuel level and remaining mileage at a fixed frequency, maintaining standard display accuracy.
[0125] Congestion Condition: When the vehicle speed remains below a set threshold (e.g., 15 km / h) for two minutes, congestion is detected. A congestion fuel consumption model is activated, calculating fuel consumption based on factors such as engine idling time and the number of starts and stops. The instrument panel updates the fuel level display at a higher frequency (e.g., every 30 seconds), using prominent signage to alert the driver to changes in fuel level.
[0126] High-speed driving conditions: When the vehicle speed exceeds 80 km / h, the fuel consumption prediction model is adjusted based on the vehicle's high-speed driving characteristics. The remaining fuel range at high speeds is highlighted on the instrument panel, and the display duration and font size of the range reminder are increased.
[0127] Bumpy Road Condition: The inertial measurement unit detects changes in vehicle acceleration and tilt angle, determining whether the vehicle is on a bumpy road. If the fuel injection amount changes by less than 15%, the fuel level display update frequency is reduced to once every 10 seconds. A weighted average algorithm is used to smooth the fuel level data, combining historical fuel level data with vehicle posture information, to stabilize the displayed value.
[0128] Optimized operating condition identification: To more accurately identify different operating conditions, a fuzzy logic algorithm is used to comprehensively analyze multi-source data. For example, when determining whether a vehicle is in a congested condition, not only vehicle speed is considered, but also factors such as engine speed, accelerator pedal position, and brake pedal usage frequency. By establishing a fuzzy rule base, the degree of membership in a congested condition is calculated based on the different value ranges of these factors. When the membership exceeds a certain threshold, a congested condition is determined, thereby improving the accuracy of operating condition identification and providing a more reliable basis for subsequent fuel quantity calculation and display strategies.
[0129] 6. Dynamic prediction of fuel quantity
[0130] Based on the integrated multi-source data, a machine learning algorithm is used to train a fuel consumption prediction model. Combining the vehicle's real-time location, navigation route, road conditions, terrain, weather, and other information, the model predicts the vehicle's remaining fuel and mileage to its destination, providing drivers with a reference for fuel planning.
[0131] Machine Learning Model Optimization: Fuel consumption prediction is performed using a long short-term memory (LSTM) network, a deep learning framework. LSTM networks are capable of processing time series data and capturing long-term dependencies in fuel consumption. The LSTM network is trained using extensive historical data to learn fuel consumption patterns under different operating and environmental conditions. Furthermore, an attention mechanism is introduced to allow the model to focus on factors that significantly influence fuel consumption, such as vehicle speed and engine load, improving prediction accuracy.
[0132] 7. Refueling detection strategy Refueling detection strategy, oil leak detection strategy, fuel sensor abnormality display strategy, vehicle stall refueling strategy, ignition refueling strategy, slope parking stability strategy and fuel level display optimization
[0133] When the fuel tank cap sensor detects an open state and the flow sensor detects a fuel flow rate greater than 0.5L / min for 10 seconds, the vehicle is considered to be refueling. The instrument display module uses dynamic animation to display the refueling progress and shows the amount of fuel added in real time. After refueling is completed, the actual amount of fuel is calculated based on the fuel level data before and after refueling, and the instrument display updates the fuel level.
[0134] 8. Oil Leak Detection Strategy
[0135] The data processing module continuously analyzes data from the flow sensor, fuel tank pressure sensor, and fuel level sensor. When the flow sensor detects a fuel outflow exceeding 0.1L / min, and the fuel tank pressure and fuel level continue to drop, the fuel leak alarm is triggered. The instrument panel alerts the driver with a flashing red icon and a beeping sound, and the leak notification is also pushed to the owner's mobile device.
[0136] 9. Display strategy when fuel sensor is abnormal
[0137] Fuel level sensor abnormality: When the data processing module detects a sudden change in fuel level sensor data (a change exceeding 20% of the total tank capacity and not corresponding to a reasonable operating condition) or a prolonged period of no change (no update for more than 5 minutes), and when other sensor data show no obvious abnormalities, the fuel level sensor is considered abnormal. At this point, the instrument display module switches to a backup display mode. Based on the fuel pump float resistor data, pressure sensor data, and historical fuel level data, the data processing module's estimation model calculates a temporary fuel level value. The instrument display displays "Fuel level sensor abnormality, current fuel level is estimated" in orange font. The fuel level display update frequency is reduced to once every 30 seconds to avoid display confusion caused by abnormal data.
[0138] Pressure sensor abnormality: If the pressure sensor data exceeds the normal range and does not match the trend of other sensor data, the pressure sensor is considered abnormal. The instrument display module displays a blue icon next to the fuel level display area indicating "Pressure sensor abnormality." The data processing module then reduces the weight of the pressure sensor data when calculating fuel level, relying more on the data from the fuel level sensor, temperature sensor, and the fuel pump float resistor conversion, ensuring that the fuel level display remains reliable.
[0139] Temperature sensor abnormality: When the temperature sensor data shows unreasonable values, the instrument display module displays a purple icon indicating "Temperature sensor abnormality." During fuel quantity calculation, the data processing module replaces the abnormal data with the default standard fuel temperature parameter and combines it with other sensor data to calculate fuel quantity. A message indicating that the actual temperature data is not being used in the current fuel quantity calculation is displayed on the instrument interface.
[0140] Simultaneous multiple sensor anomalies: If at least two of the fuel level, pressure, or temperature sensors exhibit an anomaly simultaneously, the instrument display module displays a red alert stating, "Multiple fuel sensors are anomaly; fuel level display may be inaccurate." Regular fuel level updates cease, and only the message "Fuel level data abnormal, please inspect as soon as possible" appears. At this point, the data processing module generates a rough fuel level estimate based on limited normal data (such as flow sensor data and historical vehicle fuel consumption data), attempting to update the display every five minutes to provide the driver with a minimum fuel level reference.
[0141] 10. Refueling strategy when the vehicle is turned off
[0142] When the vehicle is turned off and the fuel tank cap sensor detects that it's open, the data processing module immediately suspends all non-essential data collection and computation tasks (such as driving data collection and fuel consumption prediction), retaining only data from refueling-related sensors (flow sensor, fuel level sensor). During refueling, the instrument display module displays refueling progress in a simple and clear interface. In addition to showing the amount of fuel added, it also calculates and displays the estimated time required to fill the tank in real time (based on the current refueling flow rate and remaining tank capacity). If the vehicle experiences any abnormalities during refueling (such as a sudden interruption or unusual fluctuation in flow detected by the flow sensor), the data processing module issues an alert to alert the refueler and driver. After refueling, the data processing module restarts all data collection and computation tasks, updates the fuel resistance mapping table based on accurate fuel level data, and synchronizes the latest fuel level information to the instrument display module and the vehicle information system.
[0143] 11. Ignition and Refueling Strategy
[0144] When the vehicle's ignition is on and the fuel tank cap sensor detects an open state, and the flow sensor detects a fuel flow rate exceeding 0.5 L / min for 10 seconds, the data processing module determines that refueling is in progress. At this point, the instrument display module displays a prominent red warning message: "Refueling with the vehicle's ignition on. Safety risk!" and provides a voice notification to the driver. Simultaneously, the data processing module lowers the maximum allowable refueling flow rate (for example, from 1.5 L / min to 0.8 L / min), slowing refueling and mitigating safety risks. During refueling, key data such as engine status and fuel tank pressure are monitored in real time. If an anomaly is detected (such as sudden engine jerking or an abnormally high fuel tank pressure), refueling is immediately stopped and an emergency alarm is triggered. A flashing red icon and a beeping sound indicate "Refueling abnormality, refueling stopped" on the instrument display module. After refueling, the fuel level display and related data records are updated according to normal procedures.
[0145] 12. Slope parking stability strategy
[0146] When the inertial measurement unit detects that the vehicle's tilt angle exceeds a set threshold (e.g., 15 degrees) and the vehicle speed is zero, the data processing module determines that the vehicle is parked on a slope. At this point, the data processing module enhances the fuel level anti-shake strategy. In addition to using the existing weighted average algorithm to process fuel level data, it also compensates for the fuel level sensor data based on the vehicle's tilt direction and angle to ensure a stable fuel level display without jumps.
[0147] 13. Fuel level display optimization
[0148] The instrument display module features a dynamic visual design. When the fuel level is sufficient, the fuel gauge fills in green. When the fuel level is low but sufficient for the current trip, the gauge displays the estimated mileage in yellow. When the fuel level is nearing depletion, the gauge flashes red and sounds an alarm. A fuel consumption trend graph displays historical and predicted fuel consumption trends in real time.
