Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, including but not limited to combinations of embodiments, which can be made by one of ordinary skill in the art without inventive faculty, are intended to be within the scope of the present application, based on the embodiments herein.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims of this application and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be capable of operation in sequences other than those illustrated or described herein, for example. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Energy is the fundamental source of vehicle running power, but the energy can be supplemented everywhere because the construction degree of the current traffic infrastructure can not be realized. Therefore, when a user drives a vehicle, the user needs to pay attention to the remaining amount of energy, such as the remaining amount of gasoline, diesel oil, liquefied natural gas, and liquefied petroleum gas, for a conventional automobile, and the remaining amount of electric energy and liquefied hydrogen for a new energy automobile. The conventional prompting mechanism is to send out a prompting message, such as a fuel or electric quantity warning lamp on the instrument panel when the residual quantity is smaller than or equal to a preset threshold value.
However, if the vehicle is located at a position far from the energy supply stations such as the gas station, the charging station, the docking station, and the like, the remaining energy of the vehicle may not support the form of the energy supply station, so that the vehicle cannot run, the user can only call for rescue, and the use experience of the user is seriously affected.
In order to solve the technical problems, the invention concept of the application is as follows:
the inventor of the application finds that the situations of energy source supplement of users are divided into two types by combining experience with a large amount of user real data analysis: 1. the energy surplus is reduced to a threshold value which is considered to be insufficient by the psychology of the user; 2. users are habitually supplied with periodic energy (e.g., adding fuel or hydrogen or charging once a week or during the course of work) for a certain period of time.
Therefore, based on the historical change data of the energy surplus of the user at the vehicle-mounted terminal, the application performs preliminary characteristic engineering treatment (such as mutation analysis of the energy surplus) at the vehicle-mounted terminal, and analyzes the energy supplementing behavior (such as supplementing time and energy surplus during supplementing) of the user; then, carrying out cluster analysis to divide the sample into psychological anxiety data and/or periodic behavior data; after the far-away group points are removed, detecting whether the period sample data really has a period or not, and setting a period reminder if the period sample data really has the period; and reasonably reminding the psychological anxiety samples through different characters and different driving habits of the user.
The following describes in detail how the present application enables the transfer of information by tactile sensation.
Fig. 1 is an application scenario schematic diagram of a method for reminding of energy supplement provided in the present application. As shown in fig. 1, the vehicle 102 performs energy replenishment at the same or different energy replenishment sites 101 at different time points, and each time the replenishment is performed, the vehicle terminal records the time of replenishing the energy and the remaining amount of the energy before the replenishment. According to the method and the device, the reminding mode of energy source supplementation is adjusted through the cluster analysis of the energy source supplementation behavior of the user.
Fig. 2 is a flow chart of a method for reminding of supplementing energy according to an embodiment of the present application. As shown in fig. 2, the specific steps of the method for reminding the supplement of energy include:
s201, acquiring historical operation data and current operation data of the vehicle.
In the step, when the vehicle runs, the vehicle machine side acquires running data of the vehicle once at preset time intervals, for example, 1-5 minutes, and stores the running data to form historical running data. The current operation data is the operation data which is acquired up to date.
In the present embodiment, the history operation data includes: historical values of the energy surplus at each historical moment, and current operation data comprise: the energy surplus is the current value at the current moment.
Specifically, when the historical value of the energy remaining amount is recorded, the historical value of the energy remaining amount needs to be compared with the last energy remaining amount every time a new energy remaining amount is detected, and when the current energy remaining amount is larger than the last energy remaining amount and larger than a certain preset threshold value, the user is considered to be in progress or has completed energy replenishment, such as oiling, charging and the like, during the current detection. And the historical operation data can correspondingly record the value of the energy surplus and the corresponding time.
It will be appreciated that other data may be included in the historical operating data and the current operating data, such as current vehicle position information, current vehicle operating state information, vehicle travel state data, such as engine operating data, gearbox operating data, drive motor operating data, brake system operating data, communication system operating data, body stability system operating data, and the like.
S202, determining at least one clustering line according to the preprocessed historical operation data by using a preset clustering model.
In this step, the historical operation data may be understood as current operation data corresponding to each historical moment, where the historical operation data needs to be preprocessed to screen out data related to the behavior of the user for supplementing energy, and the data is added into a cluster sample set, and then the cluster sample set is subjected to cluster recognition through a preset cluster model, so as to obtain at least one cluster line. The preprocessing can greatly reduce the data volume for cluster recognition, eliminate the interference of noise data, reduce the data processing volume and improve the clustering efficiency.
It should be noted that, if the current operation data in S201 can also show the behavior of the user for supplementing energy, the current operation data is also added to the cluster sample set.
The cluster lines are used to characterize the driving habits and/or energy replenishment habits of the user. The clustering line includes: at least one of a straight line, a curved line, and a broken line composed of a plurality of straight line segments and/or curved line segments.
Specifically, historical operation data is subjected to preliminary screening according to a plurality of preset clustering dimensions, and the screened data is placed into a clustering sample set. In the embodiment, firstly, calculating the variation of any two adjacent recorded values in the historical operation data; then judging whether the variation meets the preset variation requirement or not; when the variation meets the preset variation requirement, the previous recorded value in the two adjacent recorded values is added into the clustering sample set.
For example, when the history operation data includes the energy remaining amount records of the energy remaining amount of the vehicle at the respective detection timings, the variation includes the difference between the first energy remaining amount record at the previous timing and the second energy remaining amount record at the subsequent timing; the preset change requirements include: the difference value is a negative value, and the absolute value of the difference value is larger than or equal to a preset charging threshold value.
It should be noted that, in order to enable the preset clustering model to adapt to the user habit changes and reduce the calculation time, the clustering sample set may set a certain capacity limit, such as a fixed value of 100, according to the LRU (Least Recently Used ) caching rule, or a capacity value that can be dynamically changed and is set according to the occurrence frequency of the energy source supplementing behavior of the user. The first-in first-out principle is then followed, and the earliest sample is rejected when the number of samples exceeds a threshold.
Next, it is necessary to perform cluster division on each sample in the clustered sample set, which is a main function of the preset cluster model. In a preset clustering model, an initial cluster line to be selected is firstly determined according to one or more preset clustering dimensions, and f is used i (x 1 ,x 2 ,……,x n ) To represent the cluster line to be selected, i represents the number of the cluster line to be selected, x n Representing each preset clustering dimension, including: time, amount of energy remaining before each replenishment, etc. Each preset clustering dimension forms a clustering space, and the essence of the clustering analysis is to find the distribution condition of each sample point in the clustering space.
The method comprises the steps of firstly randomly selecting a straight line or a curve passing through a certain sample or a plurality of sample points as an initial clustering line to be selected, then circularly calculating the Euclidean distance between each sample and the clustering line to be selected by using an Euclidean distance formula, and then solving the average distance between all samples and the clustering line to be selected. And translating the to-be-selected cluster line to the position of the sample with larger Euclidean distance, recalculating the Euclidean distance and average distance between each sample and the to-be-selected cluster line, and finally selecting the to-be-selected cluster line meeting the requirement as a cluster line, namely a cluster center line according to the preset screening requirement.
It should be noted that, in the multi-dimensional clustering space, the number of the clustering lines may be set to be equal to the number of preset clustering dimensions, and the direct distance of each clustering line may be the maximum distance as far as possible, so that the clustered multiple sample clusters may be distinguished.
It is noted that, unlike the prior art in which the points are used as the clustering centers, the clustering center of the present application is a line, so that each sample value can be maximally utilized, and the behavior habit of the user sometimes indicates a clustering rule not around the center point but around a certain straight line or curve, so that the behavior habit of the user can be fully reflected. Therefore, the preset clustering model of the embodiment of the application can be obtained by modifying the clustering center point in the Kmeans++ model into the clustering center line.
S203, determining a preset reminding range according to at least one clustering line and a preset distance threshold value, and judging whether the current operation data is in the preset reminding range.
In the step, the preset distance threshold is obtained by screening out samples with the distance greater than the preset deviation threshold from other samples in the clustered sample set, fitting the samples through a Gaussian model, obtaining the mean value mu and the variance sigma of each sample point, and then calculating the preset distance threshold according to the mean value mu and the variance sigma.
For example, the preset distance threshold d may be expressed by the formula (1):
d=Aμ+Bσ (1)
wherein a and B are dynamic parameters, which can be set according to specific application scenarios, and optionally, the value ranges of a and B can be set to [0,2], for example, a=1, b=1.5.
And calculating the distance between the current operation data and one or more clustering lines, judging whether each distance is smaller than or equal to a preset distance threshold value, and if so, considering that the current operation data is in a preset reminding range.
S204, outputting prompt information to prompt a user to supplement energy for the vehicle.
In the step, prompt information is sent to a user through a vehicle-mounted terminal, such as a vehicle-mounted display, a loudspeaker, a buzzer, an LED lamp and the like, so as to prompt the user to perform actions of supplementing energy sources, such as refueling, charging and the like, for the vehicle.
It should be noted that the clustering lines can be divided into two types, one is a time line with time as a clustering dimension, and the other is an energy line with energy remaining as a clustering dimension.
The time line is mainly used for identifying the periodic energy supplementing behavior of the user, and can also be used for carrying out auxiliary verification by adding geographic position information, and the energy line is mainly used for identifying psychological thresholds of different users, so that anxiety caused when the user forgets to check and suddenly finds that the energy remaining amount is lower than the psychological threshold is reduced.
The embodiment provides a system method for reminding of supplementing energy sources, which comprises the steps of obtaining historical operation data and current operation data of a vehicle; determining at least one clustering line according to the preprocessed historical operation data by using a preset clustering model, wherein the clustering line is used for representing the driving habit and/or the energy supplementing habit of a user; determining a preset reminding range according to at least one clustering line and a preset distance threshold value, and judging whether the current operation data is in the preset reminding range or not; if yes, outputting prompt information to prompt a user to supplement energy for the vehicle. The technical problem of how to carry out intelligent early warning prompt according to the driving habit and/or the energy supplementing habit of the user is solved. The energy supplementing prompt is timely sent out according to the running state of the vehicle and the habit of the user, so that the effectiveness of prompt information to the user is improved, and the technical effect that the vehicle cannot be used due to insufficient energy is avoided.
Fig. 3 is a flow chart of another method for reminding of supplementing energy provided in the implementation of the present application. As shown in fig. 3, the specific steps of the method for reminding the user of supplementing energy source include:
s301, acquiring historical operation data and current operation data of the vehicle.
In this step, the historical operating data includes: historical values of the energy surplus at each historical moment, and current operation data comprise: the energy surplus is the current value at the current moment.
S302, preprocessing historical operation data to determine a clustering sample set.
In this step, specifically, the method includes: calculating the variable quantity of any two adjacent recorded values in the historical operation data; judging whether the variation meets the preset variation requirement or not; when the variation meets the preset variation requirement, the previous recorded value in the two adjacent recorded values is added into the clustering sample set.
In the present embodiment, the history operation data includes the energy remaining amount records of the energy remaining amount of the vehicle at each detection timing; the variation comprises a difference value between a first energy residual record at the previous moment and a second energy residual record at the later moment; the preset change requirements include: the difference value is a negative value, and the absolute value of the difference value is larger than or equal to a preset charging threshold value.
When the historical value of the energy surplus is recorded, the energy surplus needs to be compared with the last energy surplus each time when a new energy surplus is detected, and when the current energy surplus is larger than the last energy surplus and larger than a certain preset threshold value, the user is considered to be in progress or has completed energy replenishment, such as oiling, charging and the like, during the current detection. And the historical operation data can correspondingly record the value of the energy surplus and the corresponding time. In order to adapt the preset clustering model to the habit changes of the user and reduce the calculation time, the clustering sample set may set a certain capacity limit, such as a fixed value of 100, according to the LRU (Least Recently Used ) caching rule, or a capacity value that can be dynamically changed according to the occurrence frequency of the energy supplementing behavior of the user. The first-in first-out principle is then followed, and the earliest sample is rejected when the number of samples exceeds a threshold.
S303, circularly calculating the distance between each sample data in the clustering sample set and each candidate clustering line in the clustering space.
In this step, the cluster space corresponds to a plurality of preset cluster dimensions. A plurality of preset cluster dimensions, comprising: charging time and energy surplus.
The cluster line to be selected is determined by the charging time, the energy surplus and the dimension weight. The dimension weight can adjust the charging time and the specific gravity preference when classifying the behavior habit of the user according to different clustering demands, and even can set the curve to be clustered as a dimension clustering center line only with the charging time or the energy surplus before energy supplementation.
In one possible design, the plurality of candidate cluster lines includes: a plurality of time lines corresponding to the charging time and a plurality of energy source quantity lines corresponding to the energy source surplus, wherein the time lines and the energy source quantity lines are respectively parallel to coordinate axes of the clustering space; correspondingly, the cluster line includes: the energy charging time cluster center line and the energy remaining quantity cluster center line.
In one possible design, when the cluster line to be selected is a timeline, the steps specifically include:
determining a first distance to be selected according to the time coordinate values of the sample data and the time corresponding to the time line;
Determining a second distance to be selected according to the first distance to be selected and a preset time period;
and selecting the smaller value of the first distance to be selected and the second distance to be selected as the distance.
For ease of understanding, assume that the time corresponding to the timeline is t 0 The time coordinate value of the sample data is t, then the first distance D is selected 1 Can be expressed as: d (D) 1 =|t 0 -t|, second candidate distance D 2 Can be expressed as D 2 =|t+T-t 0 I, T is a time period, for example, when t=24 represents using 24 hours as one time cycle period, so the distance D can be expressed by the formula (2):
D=min{D 1 ,D 2 } (2)
it should be noted that, since the time has its cycle special, for example, 24 is similar to 1,2 except that it is similar to 23, 22, so we consider the cycle characteristic when calculating the distance on the time axis, for example, when calculating the distance of 22 and 3, we get min (|22-3|, |3+24-22|) =5.
S304, determining at least one clustering line from the to-be-selected clustering lines according to the distances and the preset screening requirements.
Specifically, a straight line or a curve passing through a certain sample or a plurality of sample points is selected randomly as an initial clustering line to be selected, or one or more initial clustering lines to be selected are selected in a random mode, then the Euclidean distance between each sample and the clustering line to be selected is calculated circularly by using the Euclidean distance formula, and then the average distance between all samples and the clustering line to be selected is calculated. And calculating the barycenter position of each sample point, translating the to-be-selected cluster line to the barycenter position, re-calculating the Euclidean distance and the average distance between each sample and the to-be-selected cluster line, judging whether the translated to-be-selected cluster line meets the requirement according to the preset screening requirement, and if not, continuously repeating the process until the to-be-selected cluster line meeting the requirement is selected as a cluster line, namely a cluster center line.
In one possible implementation, for the two-dimensional case, i.e. two clustering dimensions exist, two clustering lines are corresponding at this time, so-called clustering is to assign all sample points to the periphery of the clustering line close to the clustering line as far as possible, and to group the sample points assigned to the same line into the same cluster; since the position of the sample point is not movable, the cluster line to be selected can be moved so that the cluster line to be selected moves towards the gravity center direction of the cluster, which is essentially to minimize the average distance of the cluster; and repeating the process, recalculating the distance between the two to-be-selected cluster lines for each sample, reassigning the cluster to which the sample points belong (because the cluster lines are moved, some sample points are possibly closer to other cluster lines), and continuously repeating the process until the to-be-selected cluster lines are balanced, namely the to-be-selected cluster lines do not need to be moved any more, or all to-be-selected cluster lines reach the center of gravity of the cluster, and the distance between all the sample points and the to-be-selected cluster lines of the cluster is smaller than or equal to the distance between the to-be-selected cluster lines of the cluster points and other cluster lines, so that the to-be-selected cluster lines can be determined to be final cluster lines.
It should be noted that, in the multi-dimensional clustering space, the number of the clustering lines may be set to be equal to the number of preset clustering dimensions, and the direct distance of each clustering line may be the maximum distance as far as possible, so that the clustered multiple sample clusters may be distinguished.
It is noted that, unlike the prior art in which the points are used as the clustering centers, the clustering center of the present application is a line, so that each sample value can be maximally utilized, and the behavior habit of the user sometimes indicates a clustering rule not around the center point but around a certain straight line or curve, so that the behavior habit of the user can be fully reflected.
Fig. 4 is a schematic diagram of a cluster line obtained by analyzing a cluster sample set provided in the present application. As shown in fig. 4, a sample point is a first type of sample point, i.e. a black sample point 401, when the abscissa of the sample point is farther from the timeline cluster centerline 42 than the ordinate of the sample point is from the cluster centerline 41, otherwise a gray sample point 402.
In one possible design, in this step, it is also necessary to further analyze the periodicity and calculate the period interval for a class of samples concentrated at a certain time, further analyze whether there is periodicity, such as daily, weekly, every two weeks, etc., if a higher probability is satisfied (so-called higher probability, say, 70% or more accords with periodicity, no strict periodicity is considered in practice, a person always has various reasons that cannot completely accord with regularity, temporary matters or oil amount is not enough to be added once in advance), we determine that there is a fueling habit of the periodicity time, so we can make fueling reminders at the periodicity time point.
S305, determining a preset reminding range according to at least one clustering line and a preset distance threshold value, and judging whether the current operation data is in the preset reminding range.
In the step, the preset distance threshold is obtained by screening out samples with the distance greater than the preset deviation threshold from other samples in the clustered sample set, fitting the samples through a Gaussian model, obtaining the mean value mu and the variance sigma of each sample point, and then calculating the preset distance threshold according to the mean value mu and the variance sigma.
In this embodiment, assuming that a cluster of samples is in a gaussian distribution, taking fueling as an example, when the remaining amount of fuel fluctuates around the user's psychological anxiety value, the user begins to feel anxiety to the situation of actual fueling, and also needs to consider the distance of the vehicle from the fueling station, and whether it is convenient to refuel at that time. According to the Gaussian distribution property, the area under the Gaussian distribution curve is 68.27% of the total area in the interval of (mu-sigma, mu+sigma); within plus or minus 2 standard deviations, i.e., within the (μ -2σ, μ+2σ) interval, the area was 95.44%, and we set the anxiety reminding value to μ+1.5σ, approximately covering 90% of anxiety cases.
If the current energy remaining amount is within the preset threshold, i.e., μ+1.5σ, it is determined that the reminding is required, and S306 is executed.
If the current time is within the range corresponding to the time line or within the periodic interval of the periodic behavior obtained by further analysis of the time lines, it is determined that the reminding is required, and S306 is executed.
S306, outputting prompt information to prompt a user to supplement energy for the vehicle.
