[0002] Sensor-based vehicle energy consumption data monitoring is to collect data by installing various sensors on the car, and then analyze the data to understand the energy consumption of the car. Usually, an oil level sensor is used to observe the vehicle's fuel consumption. When the oil level changes, the position of the oil float will also change.

[0039] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation method, structure, features and effects of a sensor-based vehicle energy consumption data monitoring method proposed by the present invention in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[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 is a detailed description of a specific solution of a vehicle energy consumption data monitoring method based on a sensor provided by the present invention in conjunction with the accompanying drawings.

[0042] See also Figure 1 , which shows a flow chart 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 the entire driving process each time.

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

[0046] Specifically, in this embodiment, several speed ranges are preset, respectively: [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 described 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 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 on the car, the dynamic changes of the fuel level are recorded in real time during multiple driving activities, and the changes in the amount of fuel in the tank are tracked, 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 amount of fuel, 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 mileage based on the average fuel consumption, and will display an estimated value indicating the distance the car can travel at the current amount of fuel, and record the estimated remaining mileage 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: according to the fuel consumption and driving distance after each driving of the vehicle, the average fuel consumption of all previous driving of the vehicle is obtained.

[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, the driver's average fuel consumption is first obtained based on previous driving data, so as to obtain the estimated remaining mileage. By comparing it with the actual mileage, the distance error caused by the driver's driving habits is further obtained, and the remaining mileage is corrected to obtain the actual mileage.

[0054] It should be noted that in order to more accurately estimate the remaining mileage of the vehicle and optimize driving habits, calculating the average fuel consumption is an important step in understanding how drivers consume fuel and evaluating the impact of different driving modes on fuel efficiency. By collecting and analyzing historical driving data, the average distance that the driver can travel for each amount of fuel consumed is determined. This indicator not only reflects the energy efficiency performance of the vehicle itself, but also comprehensively reflects the impact of driving behavior on fuel consumption. By accurately calculating the average fuel consumption, practical suggestions can be provided to drivers on how to improve driving habits to improve fuel efficiency, and key data support is also provided for estimating the remaining mileage. Compare the actual fuel consumption of each trip with the corresponding mileage to obtain the fuel consumption of each trip.

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

[0056]

[0057] Where, Y represents the average fuel consumption of the vehicle during all driving times; N is the number of times the vehicle is driven; HL is 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 is completed.

[0058] It should be noted 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 the 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 drivings is obtained.

[0061] Step S003: According to the fuel consumption and the driving distance when the vehicle speed is in each speed range during the whole process of driving the vehicle each time, the average fuel consumption when the vehicle speed is in each speed range during the whole process of driving the vehicle is obtained; according to the remaining fuel after each driving of the vehicle, the actual driving distance with the remaining fuel and the average fuel consumption of the vehicle in all previous drivings, the difference between the actual mileage and the estimated mileage is obtained.

[0062] It should be noted that the estimated remaining range is the process of calculating how far the vehicle can travel based on the current fuel level and average fuel consumption. By dividing the vehicle's fuel volume by the average fuel consumption rate, an estimated mileage can be obtained, which indicates the distance the vehicle can reach without refueling. This step is critical and can help plan the trip to ensure that you can reach your destination or the nearest gas station before the fuel runs out. The actual mileage is then compared with the estimated remaining range, and the estimation model is optimized by analyzing the differences between the actual driving data and the system's estimated results. In this process, if it is found that the actual mileage is often lower than the estimated mileage, this may indicate that the driving behavior is more fuel-intensive or that the estimation model fails to accurately capture certain driving conditions, such as frequent acceleration or dealing with congested traffic. By identifying these differences and adjusting the estimation parameters, such as recalculating the fuel consumption rate in a specific driving mode or updating the vehicle load factor, the remaining range can be predicted more accurately, thereby helping drivers plan their trips and refueling arrangements more effectively.

[0063] It should be noted that different driving speeds have different effects on fuel consumption, mainly because when driving at high speeds, the vehicle needs to overcome greater air resistance and rolling resistance, which increases the engine load and consumes more fuel to maintain power output. Specifically, as the speed increases, the air resistance increases quadratically, so the engine must burn more fuel to generate enough power to propel the car forward, so fuel consumption increases accordingly. In addition, different gear selections of the gearbox at different speeds will also affect the working state of the engine, and thus affect fuel consumption. The fluctuation of vehicle speed, especially the frequent acceleration and deceleration in urban traffic, will further aggravate the additional consumption of fuel. Therefore, it is necessary to analyze the fuel consumption at different speeds in order to accurately calculate the remaining mileage. According to the different gears of the car, the speed is segmented to obtain several speed ranges.

[0064] The calculation method of the average fuel consumption in the u-th speed range during the whole driving process is as follows:

[0065]

[0066] Where VY u It represents the average fuel consumption of the vehicle in the uth speed range during the whole 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 driving distance during the mth driving process 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 process of driving the vehicle when the vehicle speed is within the u-th speed range only counts a certain driving of the vehicle 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 in the u-th speed range during the entire driving process. The larger the value, the greater the average fuel consumption in this speed range.

[0069] It should be noted that by carefully analyzing the data after each driving activity, information about the difference between the actual mileage of the vehicle and the estimated mileage can be obtained. These data include the actual remaining mileage and the estimated remaining mileage, as well as the average fuel consumption in the overall driving situation of the vehicle. The actual remaining mileage is an actual value calculated based on the fuel level change and the driving distance recorded by the fuel level sensor, while the estimated remaining mileage is an estimated value pre-calculated by the system based on the average fuel consumption and the starting fuel level of the vehicle in previous driving. By comparing these two values, not only can we accurately understand the accuracy of the estimation system, but also any systematic deviations or individual errors that may exist, which is crucial to understanding the performance of the vehicle under different driving conditions and different driving habits. For example, if the actual mileage is usually lower than the estimated mileage, this may indicate that the driving behavior tends to be in a high-fuel consumption mode, such as rapid acceleration or high-speed driving, or it may be due to road conditions, traffic conditions or other external factors that cause the actual fuel consumption to be higher than the average level. On the contrary, if the actual mileage exceeds the estimated mileage, this may mean that the driving behavior is more energy-efficient or the vehicle is driving under more ideal road conditions.

[0070] The on-board computer system can display the vehicle's remaining fuel level; 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.

[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 is driven; L s represents the remaining fuel after the sth driving of the vehicle; Y represents the average fuel consumption of the vehicle in all previous driving; X s The actual driving distance indicating the remaining fuel after the sth driving of the vehicle is completed; 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 sth 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 an in-depth process of exploring how driver behavior affects fuel consumption and mileage. By evaluating the actual impact of driving modes (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 to 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 previous 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 mileage is performed by analyzing the difference between the actual driving data and the estimated model, with the purpose of adjusting and optimizing the estimation algorithm. This process involves re-evaluating the impact of driving behavior, road conditions, vehicle conditions, and environmental factors on fuel consumption, and updating the estimation model based on these new data inputs. By accurately adjusting the estimation parameters, the prediction of the remaining mileage can be made more accurate and closer to the actual driving situation, thereby providing drivers with more reliable driving data support. By analyzing the data from previous driving, the driver's driving behavior can be evaluated. When the difference between the actual and estimated driving distances is large, it means that the driver's driving behavior habits are poor, indicating that the remaining mileage estimated by the system should be reduced. When the difference is smaller, it means that the driver's driving habits are better. At this time, the system's estimated remaining mileage is more accurate and the revised remaining mileage is larger.

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

[0080]

[0081] In the formula, 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; It is the estimated remaining mileage within the current speed range of the vehicle being driven.

[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 according to the remaining mileage corrected 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] Among them, the saliency detection CA algorithm is a well-known technology, and the specific method is not introduced here.

[0087] What needs to be explained is that the energy consumption of the vehicle is monitored by the remaining mileage corrected at each moment. When the remaining mileage decreases abnormally, or the remaining mileage decreases at a speed beyond the normal range, the remaining mileage is detected using the significance detection CA algorithm. When there is abnormal data, it indicates that the energy consumption is abnormal. The system will promptly remind the driver of the abnormal vehicle energy consumption and solve the problem in time to avoid unnecessary fuel waste.

[0088] It should be noted that through the vehicle's remaining mileage monitoring system, the driver can not only obtain timely updates on the driving distance that the current fuel can support, but also receive energy-saving suggestions or warnings from the system based on the actual energy consumption performance of the vehicle. For example, if the monitoring system finds that the remaining mileage is abnormally reduced due to intense driving habits, or the remaining mileage decreases at a rate beyond the normal range, the system will promptly remind the driver to adjust the driving strategy to avoid unnecessary fuel waste. This intelligent monitoring not only helps the driver optimize the driving route and driving behavior, but also helps maintain vehicle performance and extend the service life of the vehicle. Moreover, this monitoring can also provide the driver with the best driving suggestions based on environmental conditions and traffic conditions, such as suggesting a more energy-saving driving method to extend the vehicle's driving distance in traffic congestion, or suggesting a constant speed when driving on the highway to reduce resistance and wind resistance, further optimizing fuel efficiency. In this way, the monitoring system not only improves driving convenience and safety, but also promotes the maximization of fuel economy, achieving the dual advantages of environmental protection 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 protection scope of the present invention.
