Description

Technical Field

[0002] Sensor-based vehicle energy consumption data monitoring involves installing various sensors on the vehicle to collect data, then analyzing the data to understand the vehicle's energy consumption. Fuel level sensors are commonly used to monitor vehicle fuel consumption. When the fuel level changes, the position of the oil float also changes. Sensors sense changes in the oil float's position, obtaining information about the liquid's level and enabling real-time monitoring of the vehicle's fuel consumption. Using fuel level sensors to observe fuel level changes, we can understand the vehicle's fuel consumption and, in turn, the remaining mileage. However, the remaining mileage calculation is affected by many factors, such as driving habits and road conditions. Frequent starting and stopping on congested roads can increase fuel consumption and reduce the remaining mileage, leading to discrepancies between the remaining mileage displayed on the vehicle and the accuracy of vehicle energy consumption monitoring.

[0038] Figure 1 This is a flow chart of the steps of a sensor-based vehicle energy consumption data monitoring method of the present invention. DETAILED DESCRIPTION

[0039] To further illustrate the technical means and effectiveness of the present invention in achieving its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, describes in detail the specific implementation, structure, features, and effectiveness of a sensor-based vehicle energy consumption data monitoring method proposed in accordance with the present invention. In the following description, references to different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0040] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0041] The following describes in detail a specific solution of a vehicle energy consumption data monitoring method based on a sensor provided by the present invention with reference to the accompanying drawings.

[0042] See also Figure 1 , which shows a flowchart of a method for monitoring vehicle energy consumption data based on a sensor according to an embodiment of the present invention, the method comprising the following steps:

[0043] Step S001: Obtain the fuel consumption, driving distance, remaining fuel, actual driving distance with remaining fuel, remaining fuel and vehicle speed of the vehicle at the current moment after each driving of the vehicle.

[0044] Several speed ranges are preset to obtain the fuel consumption and driving distance when the vehicle speed is in each speed range during each driving process.

[0045] The speed range of the driving vehicle from 0 to the maximum is divided into w speed ranges, where w is a preset number threshold, which is 5.

[0046] Specifically, in this embodiment, several speed ranges are preset: [0, 40], [40, 80], [80, 120], [120, 160], and [160, 180].

[0047] It should be noted that: when the vehicle speed is in each speed range during the entire driving process, there will be several time periods. The fuel consumption is calculated based on the fuel volume data from the beginning to the end of the time period, and the driving distance is calculated based on the duration and speed of the time period. This is a well-known calculation and will not be explained in detail here.

[0048] The car is equipped with an oil level sensor and an on-board computer system, which collects oil level data through the oil level sensor; the vehicle's fuel consumption, remaining fuel level and driving distance are calculated by the on-board computer system and displayed on the dashboard.

[0049] It should be noted that the on-board computer system calculates the actual driving distance based on the current fuel level and the vehicle's average fuel consumption rate, and displays it on the vehicle information screen.

[0050] What needs to be explained is that by installing a fuel level sensor in the car, the dynamic changes in the fuel level are recorded in real time during multiple driving activities, tracking the changes in the fuel tank, whether it is the amount of fuel added due to refueling or the amount of fuel consumed during driving. With each use of the vehicle, the fuel level sensor will capture the increase or decrease in the fuel level, and this data is then used to calculate the actual fuel consumption during each trip. Furthermore, through the collected mileage and fuel consumption data, the system can estimate the remaining range based on average fuel consumption. It will display an estimated value indicating the distance the car can travel with the current fuel level, and record the estimated remaining range for each trip.

[0051] Obtain the fuel consumption, driving distance, remaining fuel, actual driving distance with remaining fuel, remaining fuel and vehicle speed of the vehicle at the current moment after each driving of the vehicle.

[0052] Step S002: Obtain the average fuel consumption of all previous driving of the vehicle based on the fuel consumption and driving distance after each driving of the vehicle.

[0053] It should be noted that the driver's own driving behavior habits have a great impact on the actual driving distance of the vehicle. Therefore, we first obtain the driver's average fuel consumption based on previous driving data, and then obtain the estimated remaining mileage. Compared with the actual mileage, we further obtain the distance error caused by the driver's driving habits, and then correct the remaining mileage to obtain the actual mileage that can be driven.

[0054] It should be noted that calculating average fuel consumption is an important step in understanding how drivers consume fuel and assessing the impact of different driving patterns on fuel efficiency in order to more accurately estimate a vehicle's remaining range and optimize driving habits. By collecting and analyzing historical driving data, the average distance a driver can travel for each unit of fuel consumed is determined. This metric not only reflects the vehicle's energy efficiency but also comprehensively reflects the impact of driving behavior on fuel consumption. Accurately calculating average fuel consumption can provide drivers with practical advice on how to improve their driving habits to increase fuel efficiency, while also providing key data support for estimating remaining range. The actual fuel consumption of each trip is compared with the corresponding mileage to determine the fuel consumption for each trip.

[0055] The calculation method for the average fuel consumption of the vehicle during all driving times is as follows:

[0056]

[0057] Where, Y represents the average fuel consumption of the vehicle during all driving times; N represents the number of times the vehicle is driven; HL represents the average fuel consumption of the vehicle during all driving times; n Indicates the fuel consumption after the nth driving of the vehicle; X n Indicates the distance traveled after the nth driving of the vehicle.

[0058] What needs to be explained is that represents the fuel consumption of the vehicle driven for the nth time; It indicates the average fuel consumption of all driving. The higher the average fuel consumption of all driving, the worse the driver's driving habits.

[0059] What needs to be explained is that average fuel consumption can be used to evaluate the economy of driving behavior, identify trips with abnormal fuel consumption, and guide drivers to drive reasonably to reduce unnecessary fuel waste.

[0060] At this point, the average fuel consumption of the vehicle during all previous driving times is obtained.

[0061] Step S003: Based on the fuel consumption and the driving distance when the vehicle speed is in each speed range during the entire driving process of each time, the average fuel consumption of the vehicle speed in each speed range during the entire driving process of the vehicle is obtained; based on the remaining fuel after each driving process, the actual driving distance with the remaining fuel, and the average fuel consumption of the vehicle in all previous driving processes, the difference between the actual driving mileage and the estimated driving mileage is obtained.

[0062] It should be noted that the estimated remaining range is a process that calculates the vehicle's remaining range based on the current fuel level and average fuel consumption. By dividing the vehicle's fuel level by the average fuel consumption rate, an estimated range is obtained, indicating the distance the vehicle can travel without refueling. This step is crucial for trip planning, ensuring that the vehicle reaches its destination or the nearest refueling station before running out of fuel. The estimated remaining range is then compared to the actual mileage driven, and the estimation model is optimized by analyzing the discrepancies between actual driving data and the system's estimates. During this process, if the actual mileage is frequently lower than the estimated range, this may indicate fuel-intensive driving behavior or that the estimation model is not accurately capturing certain driving conditions, such as frequent acceleration or driving in heavy traffic. By identifying these discrepancies and adjusting the estimation parameters, such as recalculating the fuel consumption rate for specific driving patterns or updating the vehicle load factor, more accurate predictions of the remaining range can be achieved, helping drivers plan their trips and refueling schedules more effectively.

[0063] It's important to note that different driving speeds have varying effects on fuel consumption. This is primarily because at higher speeds, the vehicle must overcome greater air and rolling resistance, which increases the load on the engine and, consequently, fuel consumption to maintain power output. Specifically, as speed increases, air resistance increases quadratically, forcing the engine to burn more fuel to generate sufficient power to propel the vehicle forward, leading to increased fuel consumption. Furthermore, the selection of different transmission gears at different speeds also affects the engine's operating state, which in turn affects fuel consumption. Fluctuations in vehicle speed, especially the frequent acceleration and deceleration in urban traffic, further exacerbate additional fuel consumption. Therefore, it's necessary to analyze fuel consumption at different speeds to accurately calculate the remaining range. This approach involves segmenting the vehicle's speed according to its gear position, creating several speed ranges.

[0064] The calculation method for the average fuel consumption during the entire driving process when the vehicle speed is in the u-th speed range is as follows:

[0065]

[0066] Where VY u It represents the average fuel consumption of the vehicle in the u-th speed range during the entire driving process; M u Indicates the number of times the vehicle speed is in the u-th speed range during the entire driving process; VL m,u VX represents the fuel consumption during the mth driving process when the vehicle speed is in the uth speed range; m,u It represents the distance traveled during the entire process of driving the vehicle for the mth time when the vehicle speed is in the uth speed range.

[0067] It should be noted that the calculation of the average fuel consumption during the entire driving process when the vehicle speed is within the u-th speed range only counts a certain driving time when the vehicle speed is within the u-th speed range.

[0068] What needs to be explained is that It indicates the average fuel consumption of the vehicle in the u-th speed range during the entire driving process. The larger the value, the greater the average fuel consumption in the speed range.

[0069] It's important to note that careful analysis of the data after each driving session reveals discrepancies between the vehicle's actual mileage and its estimated mileage. This data includes the actual and estimated remaining range, as well as the vehicle's average fuel consumption over the entire driving pattern. The actual remaining range is calculated based on fuel level changes recorded by the fuel level sensor and distance traveled, while the estimated remaining range is a pre-calculated estimate based on the vehicle's average fuel consumption over the course of each drive and the starting fuel level. Comparing these two values ​​not only provides a precise understanding of the estimation system's accuracy but also identifies any systematic deviations or individual errors, which is crucial for understanding vehicle performance under varying driving conditions and habits. For example, if the actual mileage is consistently lower than the estimated range, this may indicate a tendency toward fuel-intensive driving patterns, such as heavy acceleration or high-speed driving, or higher-than-average fuel consumption due to road conditions, traffic conditions, or other external factors. Conversely, if the actual mileage exceeds the estimated range, it may indicate more fuel-efficient driving or ideal road conditions.

[0070] The on-board computer system can display the remaining fuel level of the vehicle; the on-board computer system calculates the actual driving distance based on the current fuel level and the average fuel consumption rate of the vehicle, and displays it on the vehicle information screen.

[0071] The difference between the actual mileage and the estimated mileage is calculated as follows:

[0072]

[0073] Where E represents the difference between the actual mileage and the estimated mileage; N represents the number of times the vehicle was driven; L s represents the remaining fuel after the sth driving of the vehicle; Y represents the average fuel consumption of the vehicle during all previous driving; X s The actual driving distance represents the remaining fuel after the s-th driving of the vehicle; is the estimated driving distance of the vehicle for the sth time; sigmoid() is the normalization function.

[0074] What needs to be explained is that represents the estimated driving distance of the vehicle for the sth time; It represents the difference between the estimated driving distance and the actual driving distance in the s-th driving of the vehicle.

[0075] What needs to be explained is that the difference between the actual mileage and the estimated mileage is obtained. Analyzing the distance error formed by driving habits is a process of in-depth exploration of how driver behavior affects fuel consumption and mileage. By evaluating the actual impact of driving patterns (such as sudden acceleration, sudden braking, or high-speed driving) on ​​fuel efficiency and comparing it with the estimated model, behavioral patterns that lead to high fuel consumption can be identified. This analysis helps provide drivers with specific feedback and suggestions, prompting them to improve their driving habits, such as adopting smoother acceleration and deceleration methods, and maintaining a constant speed, thereby optimizing fuel consumption and reducing driving costs, and helping to adjust the remaining mileage to obtain the true remaining drivable distance.

[0076] At this point, the difference between the actual mileage and the estimated mileage is obtained.

[0077] Step S004: Obtain the corrected remaining mileage at the current moment based on the difference between the actual mileage and the estimated mileage, the remaining fuel volume of the vehicle at the current moment, and the average fuel consumption corresponding to the speed range of the vehicle.

[0078] It should be noted that the calculation of the revised remaining range is performed by analyzing the differences between actual driving data and the estimated model, with the goal of adjusting and optimizing the estimation algorithm. This process involves re-evaluating the impact of driving behavior, road conditions, vehicle condition, and environmental factors on fuel consumption, and updating the estimation model based on these new data inputs. By precisely adjusting the estimation parameters, the remaining range prediction can be made more accurate and closer to actual driving conditions, thereby providing drivers with more reliable driving data support. By analyzing data from previous driving, the driver's driving behavior can be evaluated. A large difference between the actual and estimated driving distances indicates that the driver's driving habits are poor, indicating that the system's estimated remaining range should be reduced. The smaller the difference, the better the driver's driving habits, the more accurate the system's estimated remaining range is, and the larger the revised remaining range is.

[0079] The calculation method for the corrected remaining mileage at the current moment is as follows:

[0080]

[0081] Where Z represents the corrected remaining mileage at the current moment; E represents the difference between the actual mileage and the estimated mileage; L represents the remaining fuel of the vehicle at the current moment; VY represents the average fuel consumption corresponding to the speed range of the vehicle at the current moment; The estimated remaining mileage for the current speed range of the vehicle.

[0082] What needs to be explained is that Indicates the remaining mileage after correction at the current moment. The smaller the difference between the actual mileage and the estimated mileage, the greater the adjustment, and the greater the remaining mileage after correction at the current moment.

[0083] At this point, the corrected remaining mileage at the current moment is obtained.

[0084] Step S005: Monitor the vehicle energy consumption data based on the corrected remaining mileage at the current moment.

[0085] According to the above method, the corrected remaining mileage at each moment is obtained in real time, and the significance detection CA algorithm is used to detect abnormal data in the corrected remaining mileage at each moment obtained in real time; when abnormal data appears, it indicates that the vehicle energy consumption is abnormal, and the problem is solved in time to avoid unnecessary fuel waste.

[0086] The saliency detection CA algorithm is a well-known technology, and the specific method will not be introduced here.

[0087] What needs to be explained is that the vehicle's energy consumption is monitored through the corrected remaining mileage at each moment. When the remaining mileage decreases abnormally, or the remaining mileage decreases at a rate beyond the normal range, the significance detection CA algorithm is used to detect the remaining mileage. When there is abnormal data, it indicates abnormal energy consumption. The system will promptly remind the driver of the vehicle's energy consumption abnormality and solve the problem in a timely manner to avoid unnecessary fuel waste.

[0088] It's important to note that the vehicle's remaining range monitoring system not only provides drivers with timely updates on the range their current fuel level can support, but also provides energy-saving recommendations and warnings based on the vehicle's actual energy consumption. For example, if the monitoring system detects an abnormally low remaining range due to aggressive driving, or if the rate of decline exceeds expectations, the system will promptly alert the driver to adjust their driving strategy to avoid unnecessary fuel waste. This intelligent monitoring not only helps drivers optimize their routes and driving behavior, but also helps maintain vehicle performance and extend its lifespan. Furthermore, this monitoring system can provide optimal driving recommendations based on environmental and traffic conditions, such as suggesting a more fuel-efficient driving style to extend the vehicle's range in congested traffic or recommending a constant speed on highways to reduce drag and wind resistance, further optimizing fuel efficiency. In this way, the monitoring system not only improves driving convenience and safety, but also maximizes fuel economy, achieving both environmental and cost-effectiveness.

[0089] At this point, this embodiment is completed.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the scope of protection of the present invention.
