The half-load state may belong to a normal running state of the vehicle, and may be ignored and only a full-load state and an empty-load state may be considered in order to promote efficiency of subsequent calculation.
In an embodiment, after acquiring each data, each data may be incomplete or have repeated data, and in order to perfect each data, in an embodiment, after step S11, the method may further include:

In a specific operation mode, it may be determined whether the engine speed included in the current running data is greater than a preset speed value, if the engine speed is greater than the preset speed value (for example, 100 rpm), it may be determined whether the vehicle speed included in the current running data is greater than a vehicle speed value, if the vehicle speed value is greater than the vehicle speed value (for example, 15 km/h), and the duration is greater than a preset duration, it may be determined that the vehicle is currently starting.
Then, the corresponding value of the running gradient angle can be determined, and if the running gradient angle is a negative value, the vehicle can be judged to be started on a downhill slope; if the driving gradient angle is smaller than or equal to a preset angle (for example, 3 degrees), the vehicle can be judged to be started on a flat road; if the driving gradient angle is greater than a preset angle (for example, 3 degrees), the vehicle can be judged to be started on an uphill.
After determining the starting state and the loading state, the two states may be combined to determine the starting type of the vehicle.
Referring specifically to fig. 3, in an alternative embodiment, step S12 may include the sub-steps of:
and S123, if the starting state is downhill starting and the real-time load state is no-load state, determining that the starting type of the vehicle is no-load downhill type.

And S125, if the starting state is flat road starting and the real-time load state is no-load state, determining that the starting type of the vehicle is no-load flat road type.
And S126, if the starting state is a flat road starting state and the real-time load state is a full load state, determining that the starting type of the vehicle is a full load flat road type.
And S127, if the starting state is uphill, and the real-time load state is no-load state, determining that the starting type of the vehicle is no-load uphill.
And S128, if the starting state is uphill starting and the real-time load state is full load state, determining that the starting type of the vehicle is full load uphill type.

According to the foregoing, the vehicle is started in various types, whether the vehicle is started in an unreasonable manner can be determined according to the starting type, if not, the real-time oil consumption of the vehicle can be immediately calculated, and the driver is reminded of adjusting the driving manner through the oil consumption.
In one embodiment, the unreasonable launch may be: full load uphill start and the driver performs a skip gear treatment on the vehicle.
The jump starting can be as follows: the operation of directly engaging in a higher gear from the next gear of the current gear skipping up gear is gear skipping, and the starting mode including gear skipping operation in the vehicle starting process is gear skipping starting.
In one embodiment, step S13 may include the sub-steps of:
s131, when the starting type is a full-load ascending type, acquiring starting gear data of the vehicle within a preset time period, wherein the starting gear data comprise an initial gear number, an upshift frequency and a downshift frequency.
In one embodiment, the shift operation of the vehicle during the hill start may be determined according to a gear identification model that determines a gear according to parameters such as a clutch signal, a brake switch state, a vehicle speed, an engine speed, an accelerator opening, and a cyclical fuel injection amount.
Referring to FIG. 4, a flow chart illustrating the operation of shift identification provided by an embodiment of the present invention is shown.
In a specific implementation, it may be determined whether a clutch signal of the vehicle is received, and if the clutch signal is received, the brake switch state is processed to be closed, the vehicle speed is greater than zero, and the engine speed is greater than a preset value (e.g., 400 rpm), it may be determined that the vehicle is likely to be shifted. At this time, the fuel injection amount of the vehicle engine or the accelerator pedal opening degree can be obtained; if the fuel injection amount of the vehicle engine is equal to zero or the opening degree of the accelerator pedal is equal to zero, and the state is continuously smaller than a preset duration (for example, 2 seconds), the state can be defined as the first working condition.
Then, the first engine speed N of the vehicle may be obtained before the first operating condition is entered, respectively A After exceeding the preset time period, the second engine speed N of the vehicle B And a third engine speed N one second after the second engine speed C 。
If the third engine speed N C Is greater than or equal to a first preset speed value (e.g., 650 rpm), and a first engine speed N A And a second engine speed N B The difference in (c) is greater than or equal to a second preset rotational speed value (e.g., 100 rpm), a shift of the vehicle may be determined to be an upshift. If the third engine speed N C Is greater than or equal to a first preset speed value (e.g., 650 rpm), and a first engine speed N A And a second engine speed N B The difference in (c) is less than or equal to a third preset rotational speed value (e.g., -100 rpm), a shift of the vehicle may be determined to be a downshift.
And S132, if the difference value between the initial gear number and the upshift frequency is smaller than or equal to the downshift frequency, determining that the starting of the vehicle is of an unreasonable type.
After the upshift or downshift is determined, the initial gear number, the upshift number, and the downshift number of the vehicle may be counted. And then determining whether the driver performs a gear-shifting operation on the vehicle according to the initial gear number, the gear-shifting frequency and the gear-shifting frequency.
If the gear jump operation is performed, the starting of the vehicle can be determined to be of an unreasonable type.
In particular, referring to fig. 5, a flowchart of the operation of skip shot identification provided by an embodiment of the present invention is shown.
In one implementation, when the launch type is a full-load uphill type, the first gear of the vehicle may be identified within 5 seconds from the end of the launch, resulting in an initial gear (e.g., 1 or 2, etc.). Meanwhile, whether the vehicle is upshifted or downshifted in the next operation can be determined in the manner of fig. 4 described above, and the upshift and downshift times can be counted. Wherein, the initial gear number is marked as A, the up-shift number is marked as U, and the down-shift number is marked as D.
If the initial gear number a-upshift number U is less than or equal to the preset shift number (for example, 1), and the decrease number D is the preset decrease number (for example, 0), it may be determined that the vehicle is started in a skip gear, and it may be determined that the vehicle is started in an unreasonable type. Otherwise, the vehicle can be determined to be started in a step-by-step gear shifting mode, and the vehicle can be determined to be started in a reasonable mode.
And S14, when the starting of the vehicle is determined to be of an unreasonable type, acquiring real-time operation data of an engine of the vehicle, calculating a real-time oil consumption value of the vehicle by adopting the real-time operation data, and carrying out oil consumption reminding according to the real-time oil consumption value.
According to the foregoing description, there are various types of starting, and some types of starting may be reasonable or normal types of starting; and if the starting type is the unreasonable type, the real-time running data of the vehicle engine can be obtained through the additionally arranged R-BOX equipment, and then the real-time oil consumption value of the vehicle is calculated by adopting the real-time running data.
And finally, the fuel consumption reminding can be carried out according to the real-time fuel consumption value, so that the driver is reminded that the current driving mode possibly generates high fuel consumption, and the driver is reminded of modifying the driving mode.
In an embodiment, the calculation formula of the real-time fuel consumption value is as follows:
sum=speed/a number of cylinders of the engine/speed per cycle/quantity of fuel injected per cycle/B/fuel density;
the SUM is a real-time oil consumption value, and the A and the B calculate constants.
In an alternative embodiment, starting fuel consumption (L) =sum (starting condition single measurement fuel consumption) =sum real-time fuel consumption value=engine speed/60×engine cylinder number/per cycle speed×cycle fuel injection quantity/1000000/fuel density.
In an embodiment, the fuel consumption of the vehicle can be judged according to the scientific starting fuel consumption standard. The scientific starting oil consumption can be as follows: the average value of the latest 100 times of full-load uphill scientific starting oil consumption (L) is determined as an oil consumption standard, and the standard value after each time of scientific starting is averaged according to the value of the previous 100 times.
The fuel consumption value of the single full-load uphill starting driving behavior can be calculated according to the collected vehicle operation data. When the full-load uphill starting mode is unreasonable, the oil consumption of the starting is compared with the oil consumption standard of the scientific starting, and the oil reduction potential of the single starting of the vehicle is calculated.
In an embodiment, the fuel consumption reminding mode may be a voice reminding mode. When the vehicle starts in the journey, the vehicle is identified and judged in the starting process. When the starting process is judged to be the full-load starting of the ramp, judging the rationality of the starting and following the following strategy of voice broadcasting:
when 100 times of full-load uphill starts are completed in an accumulated way, carrying out voice broadcasting on the ratio of scientific starts in 100 times of starts;
wherein, broadcast the mode: and immediately triggering voice broadcasting after the full-load uphill starting times are counted to be 100 times, and after voice broadcasting, accumulating the full-load uphill starting times from 0 again until the full-load uphill starting times reach 100 times again, triggering voice broadcasting, wherein the triggering logic of follow-up broadcasting is consistent.
Broadcasting content reference: 100 starts recently, with scientific starts reaching 60% (configurable), please continue hold (> 60%)/boost (< 60%).
In the journey, unreasonable starting behaviors appear in the uphill heavy-load starting scene, a voice broadcasting training function is immediately triggered, and the following voice training is performed:
and when the vehicle is started in a full load on an ascending slope and the current starting gear and the gear shifting mode do not meet the 1-gear starting and step-by-step gear shifting conditions, triggering voice training broadcasting when the user stops next time. For example: the front uphill full load starting mode of the vehicle can be optimized: starting at 1 gear when the uphill is fully loaded, gradually upshifting, and starting by using a flash accelerator is more scientific.
In yet another alternative embodiment, after the reminding is finished, the detailed analysis data of the current service trip starting working condition is pushed to the user through the mobile phone APP of the end user, which may include the total number of current trip starts, the number and the duty ratio of full-load uphill scientific starts, and may also include refined numerical values such as average starting time, average starting mileage and the like.
Through the journey analysis, the user can more intuitively see the index data of the specific journey, and the scientificity of the driving behavior of the driver can be improved by combining the scientific starting voice broadcasting content, so that the fuel economy in the driving process is effectively improved, and the loss of vehicle parts is reduced. The method can not only cultivate the usage habit of a driver for analysis of related indexes of driving behavior and fuel economy, but also accumulate related data, and provide data support for subsequent business expansion.
Referring to fig. 6, an operation flowchart of a method for reminding a vehicle of fuel consumption during climbing is shown.
Specifically, the current running data of the vehicle and the gradient data of the current location of the vehicle may be acquired in an online manner. When the vehicle starts, the real-time load state of the vehicle is identified through the load model, the starting state of the vehicle is identified through the uphill and downhill identification model, the starting type of the vehicle can be determined by combining the real-time load state and the starting state, finally, whether the starting mode of the vehicle is unreasonable or not can be determined according to the starting type of the vehicle, if the starting mode is unreasonable, oil consumption calculation can be immediately carried out, and a driver is informed of driving adjustment through real-time oil consumption, so that the effect of reducing the oil consumption is achieved.
The invention can comprehensively consider and analyze the actual running condition of the vehicle, road conditions, driving behaviors of the driver and other factors, calculate whether the vehicle has unreasonable full-load uphill starting behaviors currently in real time, delay the voice broadcast reminding to the driver and provide the analysis content of the journey scientific starting driving behaviors. Meanwhile, through detailed data analysis and visual display forms of APP and web, a driver is more sensitive to scientific starting, and driving behaviors are promoted to be improved.
Meanwhile, the enthusiasm of the user for improving the driving behavior is improved, the fuel economy of the vehicle is improved, the abrasion of the vehicle parts in the starting process is reduced, and the vehicle cost is saved for the user in the long term.
It should be noted that the invention can be applied to the situation that the ramp is more in the business process, that is, the situation that the terrain of row Cheng Zhongshan is larger and the vehicle has a larger probability of having hill start in the business process.
And meanwhile, the load of the vehicle is required to be identified, and the hill start driving behavior of the vehicle is analyzed in a model mode and whether the vehicle starts scientifically is output only when the load in the journey of the user is identified as full load. When the driver finishes 100 times of starting (configurable) in an accumulated way, a statistical voice broadcast of the scientific starting ratio is received. When unreasonable starting is generated in the business trip, scientific starting voice broadcasting is provided for a driver immediately, and a starting behavior analysis report is provided after the single business trip is finished.
