Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The vehicle coasting is a phenomenon that a driver releases an accelerator pedal (a throttle valve is completely closed) during the running process of the vehicle, so that an engine does not need to output torque, and the vehicle can continuously move forward under the dragging of previous kinetic energy, and the working condition is called coasting.
During the sliding process, the generator does not output torque any more, and the engine does not need to be started with fuel consumption, so that fuel can be saved. In order to calculate the amount of fuel oil saved during the sliding process, a commonly used method at present is to obtain a total travel distance and a sliding distance of a vehicle within a preset time period, calculate an actual distance of the vehicle by using the two total travel distances and the sliding distance, calculate a total fuel consumption corresponding to the total travel distance and an actual fuel consumption corresponding to the actual distance by using a unit fuel consumption value of the vehicle, and determine a fuel consumption saving value for sliding according to a difference value of the two fuel consumptions.
However, the currently used method has the following technical problems: the sliding states of the vehicles are various (such as sliding with gear, sliding in neutral gear or both sliding with gear and sliding in neutral gear), the fuel consumption saved by different sliding is different, and some vehicles are still in the fuel consumption state in the sliding process, so that the statistical sliding distance of the vehicles and the actual sliding distance of the vehicles without fuel consumption are deviated, the calculated fuel consumption saving value is inaccurate, and the error is large.
In order to solve the above problem, a method for calculating fuel saving regarding a vehicle coasting state provided by the embodiments of the present application will be described and illustrated in detail by the following specific embodiments.
In an embodiment, the method is suitable for a vehicle-mounted terminal or a cloud platform connected with a vehicle, and both the vehicle-mounted terminal and the cloud platform can be in communication connection with an intelligent terminal of a vehicle driver so that the driver can acquire data of the vehicle from the cloud or the vehicle-mounted terminal through the intelligent terminal.
Referring to fig. 1, a flowchart of a method for calculating fuel economy in a vehicle coasting state according to an embodiment of the present invention is shown.
As an example, the method for calculating fuel economy in a vehicle coasting state may include:
s11, collecting a driving data set of the vehicle within a preset first time length.
In one embodiment, the driving data set may include various driving parameters of the vehicle, such as speed, driving duration, fuel injection, throttle status, acceleration, vehicle driving environment, tire pressure, mileage, and the like. The preset first duration may be a certain period of time, for example, one day, half day, 8 hours or one week, etc., during which the driver drives the vehicle, and may be specifically adjusted according to actual needs.
In an optional implementation mode, the vehicle can be provided with an R-BOX device (or an on-vehicle T-BOX device is directly used, and aiming at the condition that the T-BOX device is installed when the vehicle leaves a factory), vehicle operation data is collected in real time through the R-BOX device or the T-BOX device, and various data are gathered together to obtain a driving data set.
In an embodiment, the collected data has multiple types, and if all the data are used for subsequent analysis and calculation, the calculated data amount is large, the time consumption is long, and the data may contain useless data, and in order to reduce the processed data amount and improve the processing efficiency of the data, as an example, step S11 may include the following sub-steps:
and S111, acquiring real-time data of the vehicle during running by using the R-BOX equipment of the vehicle.
And S112, preprocessing the real-time data to obtain a driving data set, wherein the preprocessing comprises sequentially identifying, screening and classifying.
Specifically, real-time data of a vehicle during running can be collected by the R-BOX device, the data are stored in the cloud, and when the collected duration is equal to the preset first duration, the data in the time interval of the preset first duration are preprocessed to obtain a running data set.
Wherein the preprocessing comprises data identification, data screening and data classification.
Data identification specifically identifies the time dimension of the data. For example, the acquired data may have a time dimension of 1 second, 0.5 second, or 3 seconds.
The data screening is to remove data with a data time dimension smaller than a preset time dimension, for example, if the preset time dimension is 1 second, data with a time dimension larger than or equal to 1 second is retained, and data with a time dimension smaller than 1 second is removed.
The data classification is to divide each data into oil injection quantity, speed, mileage and the like.
And S12, determining the sliding type of the vehicle based on the fuel injection quantity in the running data set.
During the sliding process of the vehicle, no oil injection or small oil injection is possible, the sliding type of the vehicle can be determined according to the oil injection amount of the generator, and therefore the calculation of the oil consumption and the oil saving amount can be carried out according to the actual sliding type of the vehicle.
In an alternative embodiment, the coasting types include single-gear coasting, single-neutral coasting, and both-gear and neutral coasting.
Wherein, the independent drive sliding is the continuous sliding with gear of the vehicle. The single neutral coasting is the coasting in which the vehicle continues to coast. The two states of the vehicle, namely driving and neutral gear, are adopted in the process of coasting, and the vehicle can be switched back and forth in the two states in the process of coasting.
Wherein, as an example, step S12 may comprise the following sub-steps:
s121, extracting the running speed, the accelerator opening and the initial fuel injection quantity value of the vehicle from the running data set, and counting the duration that the accelerator opening is equal to a preset opening value and the duration is greater than or equal to a preset second duration, the running speed is greater than or equal to a preset first speed value and the initial fuel injection quantity value is less than or equal to a preset first fuel quantity value to obtain the fuel quantity change duration, wherein the preset second duration is less than the fuel quantity change duration, and the fuel quantity change duration is less than the preset first duration.
And S122, extracting a plurality of fuel injection quantity values from the driving data according to the fuel quantity change duration.
And S123, if each oil injection quantity value is smaller than a preset second oil quantity value, determining that the sliding type of the vehicle in a preset first time length is the single sliding with the gear.
And S124, if each oil injection quantity value is larger than a preset second oil quantity value and smaller than a preset first oil quantity value, determining that the sliding type of the vehicle in a preset first time length is the single neutral sliding.
And S125, if not, determining that the sliding type of the vehicle in the preset first time length is the geared and neutral sliding.
In a real time, whether the vehicle slides or not can be determined, after the vehicle slides, the duration of the change of the fuel injection quantity of the vehicle during sliding can be counted, the fuel injection quantity of the duration of the change of the fuel injection quantity can be further obtained, and the sliding type of the vehicle can be determined according to the fuel injection quantity.
Referring to fig. 2, a flowchart of the operation of the coasting judgment provided by an embodiment of the present invention is shown.
To illustrate with an alternative operation example, assuming that the driver does not depress the accelerator for a certain period of time (the accelerator opening is equal to 0 and the duration is greater than or equal to 5 seconds), the vehicle is in a running state (the running speed is greater than or equal to 20) and the generator of the vehicle has fuel injection (the initial fuel injection amount is less than or equal to 40 liters per hour), it is determined that the vehicle is handling a coasting state, and the duration of the period of time is counted to obtain the fuel amount change duration.
The duration of the vehicle in the sliding state is counted, the data of the fuel injection quantity in the duration can be obtained, and the sliding type of the vehicle can be accurately determined according to the fuel injection quantity.
Specifically, a plurality of fuel injection quantity values within the fuel quantity change duration may be obtained, and assuming that the fuel quantity change duration is 10 seconds, one fuel injection quantity value is obtained every 1 second to obtain 10 fuel injection quantity values, or one fuel injection quantity value may be obtained every 2 seconds or one fuel injection quantity value may be obtained every 0.5 seconds. The method can be adjusted according to actual requirements.
After the plurality of oil injection quantity values are obtained, each oil injection quantity value can be respectively judged, and when each oil injection quantity value is smaller than a preset second oil injection quantity value, the sliding type of the vehicle in a preset first time length is determined to be single sliding with a gear; if each oil injection quantity value is larger than a preset second oil quantity value and smaller than a preset first oil quantity value, determining that the sliding type of the vehicle in a preset first time length is single neutral sliding; in addition, if all the conditions remain, the coasting type of the vehicle within the preset first time period is determined to be the coasting in neutral gear.
Wherein the preset second oil amount value is smaller than the preset first oil amount value.
Referring to fig. 3, a flowchart of operations for identifying a coasting type according to an embodiment of the present invention is shown.
When each fuel injection quantity value is less than 3 liters per hour, determining that the sliding type of the vehicle in a preset first time period is single sliding with gears; when each fuel injection quantity value is larger than 3 liters per hour and smaller than or equal to 40 liters per hour, determining that the sliding type of the vehicle in a preset first time period is independent neutral sliding; and when one fuel injection quantity is less than 3 liters per hour, the rest fuel injection quantity values are all more than 3 liters per hour and less than or equal to 40 liters per hour, or one fuel injection quantity is more than 3 liters per hour and less than or equal to 40 liters per hour, and the rest fuel injection quantity values are all less than 3 liters per hour, and the coasting type of the vehicle in the preset first time period is determined to be the coasting with the gear and in the neutral gear.
The actual sliding type of the vehicle in the sliding process can be accurately distinguished through the fuel injection quantity, and further the fuel consumption saving quantity can be calculated according to the sliding type.
And S13, calculating the fuel consumption saving value of the vehicle sliding according to the sliding type.
In one embodiment, the fuel consumption corresponding to the coasting type may be obtained, and the fuel consumption saving value may be calculated based on the fuel consumption.
In one embodiment, step S13 may include the following sub-steps:

And S132, calculating the difference value between the prior oil consumption value and the sliding oil consumption value to obtain an oil consumption saving value.
Referring to fig. 4, a flowchart illustrating an operation of calculating the fuel consumption saving value according to an embodiment of the present invention is shown.
In actual operation, the hundred kilometer fuel consumption value of a vehicle before the vehicle enters the fuel quantity change duration can be obtained, and a prior fuel consumption value is obtained; then, the fuel consumption value of the vehicle in hundred kilometers within the time length of the oil quantity change can be obtained, and the sliding fuel consumption value is obtained. And finally, subtracting the sliding oil consumption value from the prior oil consumption value to obtain an oil consumption saving value.
In order to facilitate the user to view the fuel consumption saved by the vehicle during the coasting process, for example, after determining the fuel consumption saving value, the method may further include:

In the chart, the chart may further include a statistical report (the ratio of total mileage during coasting, the ratio of total time during coasting, the ratio of total fuel consumption during coasting, and the ratio of coasting between vehicle speeds), and a coasting classification detail report (the coasting start speed interval of coasting with gear, coasting with neutral, and coasting with neutral + with gear, the coasting duration, the coasting mileage, the coasting fuel consumption, the ratio of duration to mileage, the fuel consumption in hundred kilometers, and the actual fuel saving). Through detailed data analysis, a driver can visually know fuel saved by sliding, and the fuel reduction potential of the driver under the same road condition is judged subjectively.
