Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in 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.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a service publishing method according to an exemplary embodiment of the present application. The service publishing system 100 includes a data collecting module 110, a data reporting module 120, and a service publishing module 130. The data collection module 110 is used to collect vehicle-end data, such as speed, acceleration, and ignition signal of the vehicle. The data reporting module 120 is configured to report the data collected by the data collecting module 110 to the service publishing module 130. The service issuing module 130 is configured to decide a service issuing scheme according to the received vehicle-end data, and execute a service issuing operation. The data collection module 110, the data reporting module 120 and the service publishing module 130 are deployed on the same vehicle.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a service publishing method according to an embodiment of the present disclosure. The service distribution method may be applied to the service distribution module 130 in the service distribution system 100 shown in fig. 1, or the service distribution apparatus 200 shown in fig. 6, which will be mentioned below, or the vehicle 300 shown in fig. 7, which will be mentioned below. The service delivery method may include the following steps S110-S130.
And step S110, acquiring vehicle end resource utilization rates of the vehicle in multiple operation stages, wherein the multiple operation stages are divided according to the operation state of the vehicle and the vehicle end resource utilization rates.
The operating phases are the phases that the vehicle is in during driving. The plurality of operating phases may include, but are not limited to, a pull-off phase, a sleep phase, an acceleration phase, and a smooth operation phase. The plurality of operating phases may be predetermined before the service delivery starts, or may be determined in the service delivery process.
The vehicle-end resource utilization rate refers to the current utilization rate of all hardware resources at the vehicle end, namely the ratio of the occupied amount to the total amount of all the hardware resources at the vehicle end. One operation stage can correspond to at least two vehicle end resource utilization rates. For example, the vehicle-end resource utilization rate corresponding to the highest risk time and the vehicle-end resource utilization rate corresponding to the lowest risk time.
In some embodiments, the steps of dividing the plurality of operating phases are as follows: acquiring the running state of a vehicle, the utilization rate of vehicle-end resources, an ignition signal, a speed signal and an acceleration signal; and dividing a plurality of operation stages according to the operation state, the utilization rate of vehicle-end resources, the ignition signal, the speed signal and the acceleration signal.
The running state of the vehicle refers to an operating condition of the vehicle during running. For example, in terms of the form of motion of the vehicle, the operating state of the vehicle may include, but is not limited to, take off, acceleration, constant speed, deceleration, turning, uphill or downhill, and stopping. In terms of the control scheme employed by the driver, the operating state of the vehicle may include, but is not limited to, shifting, coasting (e.g., coasting off gear, coasting on neutral, coasting on acceleration, coasting off park), braking (e.g., emergency braking, speed control, braking), throttle control, steering, and reverse.
The vehicle can directly read the current running state of the vehicle, the utilization rate of vehicle-end resources, an ignition signal, a speed signal and an acceleration signal.
In some embodiments, the step of dividing the plurality of operating phases according to the operating state, the vehicle end resource utilization rate, the ignition signal, the speed signal and the acceleration signal is as follows: identifying a resource utilization rate mutation point according to the running state and the vehicle-end resource utilization rate; dividing a plurality of operation stages according to the resource utilization rate catastrophe point, the ignition signal, the speed signal and the acceleration signal; and acquiring service running time, matching the service running time with the time corresponding to the multiple running stages, and determining the service sequence corresponding to the multiple running stages.
Because the change of the vehicle-end resource utilization rate is caused by the change of the operation stage, the resource utilization rate change point can be identified according to the operation state and the vehicle-end resource utilization rate, and the operation stage is divided according to the resource utilization rate change point, the ignition signal, the speed signal and the acceleration signal. After the operation stages are divided, the service can be matched with the time corresponding to the plurality of operation stages according to the service operation time to determine the service sequence corresponding to each operation stage, so that the vehicle-end resource utilization rate corresponding to each operation stage can be calculated according to the resource occupied by the service sequence corresponding to each operation stage.
After the operation stage is determined, the service sequences corresponding to the operation stage can be obtained, and the vehicle-end resource utilization rate of the vehicle in the multiple operation stages is respectively calculated according to the service sequences corresponding to the multiple operation stages.
In some embodiments, the first preset relationship function between resource utilization rate of the service P, the operation phase of the vehicle, and the time may be represented as X (C, T, P), where X represents resource utilization rate of the service, C represents the operation phase of the vehicle, and T represents the time. The second preset relationship function between the vehicle-end resource utilization rate, the operation phase of the vehicle and the time can be represented as Q (C, T, P1, P2, \8230;, pn), wherein Q represents the vehicle-end resource utilization rate, C represents the operation phase of the vehicle, T represents the time, and P1-Pn represent the services installed or to be installed by all the users. The function analytic expression of the second preset relation function lambda Q (C, T, P1, P2, \8230;, pn) and the first preset relation function X (C, T, P) can be obtained by fitting based on historical data or simulation environment test data. It should be noted that n and m which will be mentioned next in the embodiments of the present application are positive integers.
As an example, when the service P1 is triggered at the time T1, T2, and T3 of the operation phase C, the vehicle-end resource utilization rate and the service resource utilization rate corresponding to the time T1, T2, and T3 may be recorded as shown in table 1.
TABLE 1
And calculating the vehicle-end resource utilization rate at the highest risk moment and the vehicle-end resource utilization rate at the lowest risk moment corresponding to the multiple operation stages according to the service sequences corresponding to the multiple operation stages. The highest risk moment refers to a moment when the possibility that the vehicle cannot respond in time or even has the largest stuck problem occurs, and the utilization rate of vehicle end resources is generally higher at the moment. The minimum risk moment refers to a moment when the possibility that the vehicle cannot respond in time or even the possibility of the stuck problem is minimum, and the utilization rate of vehicle-end resources is usually low at the moment.
In some embodiments, calculating the vehicle-end resource utilization rate at the highest risk moment in each operation stage comprises the following steps: and calculating the sum of the highest resource utilization rate of the service P and the highest resource utilization rates of other services to serve as the vehicle-end resource utilization rate at the highest risk moment, wherein the service P is any installed service or service to be installed.
For example, the service P operates during the operating phases C1, C2, \8230;, cm of the vehicle. At the time T1 of the operating phase Ci, the resource utilization rate of the service P is at most X (Ci, T1, P), where i is less than or equal to m and greater than or equal to 1. At the time of T2 in the operation stage of the Ci, the resource utilization rate of other services is the highest Q (Ci, T2, P1, P2, \8230;, pn) -X (Ci, T2, P1), and then the vehicle-side resource utilization rate H (Ci) at the time of the highest risk in the operation stage of the Ci is calculated according to the following expression:
H(Ci)＝X(Ci,T1,P)+[Q(Ci,T2,P1,P2,…,Pn)-X(Ci,T2,P1)]。
in some embodiments, calculating the vehicle-end resource utilization rate at the lowest risk moment of each operation stage comprises the following steps: and calculating the sum of the minimum resource utilization rate of the service P and the minimum resource utilization rates of other services to serve as the vehicle-end resource utilization rate at the moment of the lowest risk. Where the service P is any installed or to be installed service.
For example, at time T3 of the Ci runtime phase, the resource utilization of service P is at the lowest X (Ci, T3, P), where i is less than or equal to m and greater than or equal to 1. At the time of T4 in the Ci operation stage, the resource utilization rate of other services is the lowest Q (Ci, T4, P1, P2, \8230;, pn) -X (Ci, T4, P1), and then the vehicle-side resource utilization rate L (Ci) at the time of the lowest risk in the Ci operation stage is calculated according to the following expression:
L(Ci)＝X(Ci,T3,P)+[Q(Ci,T4,P1,P2,…,Pn)-X(Ci,T4,P1)]。
according to the method, the vehicle end resource utilization rates of the multiple operation stages can be obtained through calculation, and comprise the vehicle end resource utilization rates at the highest risk moments of the multiple operation stages and the vehicle end resource utilization rates at the lowest risk moments of the multiple operation stages. For example, the vehicle-end resource utilization rate at the time of the highest risk in a plurality of operation phases is H (C1), H (C2), H (C3), \8230;, H (Cm). The utilization rate of the vehicle-end resources at the time of the lowest risk in a plurality of operation stages is L (C1), L (C2), L (C3), \ 8230;, L (Cm).
And step S120, determining the utilization rate of the target vehicle end resources according to the utilization rates of the vehicle end resources in a plurality of operation stages.
The target vehicle-end resource utilization rate comprises at least one of a vehicle-end resource utilization rate corresponding to the highest risk moment and a vehicle-end resource utilization rate corresponding to the lowest risk moment.
According to the vehicle resource utilization rate of the multiple operation stages, the target vehicle end resource utilization rate can be determined from the vehicle end resource utilization rates of the multiple operation stages.
In some embodiments, the target vehicle-end resource utilization rate is a vehicle-end resource utilization rate corresponding to the highest risk time, and a maximum value of the vehicle-end resource utilization rates of the plurality of operation stages may be determined as the target vehicle-end resource utilization rate. For example, the maximum value among all of the vehicle-end resource utilization rates H (C1), H (C2), H (C3), \8230;, H (Cm) and L (C1), L (C2), L (C3), \8230;, L (Cm) may be determined as the target vehicle-end resource utilization rate. Because the vehicle-end resource utilization rate at the highest risk moment is often greater than that at the lowest risk moment, the maximum value MAX (C) in the vehicle-end resource utilization rates H (C1), H (C2), H (C3), \ 8230;, H (Cm) at the highest risk moment in a plurality of operation stages can be determined as the target resource utilization rate, so as to save the calculation time.
In other embodiments, the target vehicle resource utilization rate is a vehicle-end resource utilization rate corresponding to the lowest risk time, and a minimum value of the vehicle-end resource utilization rates in a plurality of operation phases may be determined as the target vehicle-end resource utilization rate. For example, the minimum value among all of the vehicle-end resource utilization rates H (C1), H (C2), H (C3), \8230;, H (Cm) and L (C1), L (C2), L (C3), \8230;, L (Cm) may be determined as the target vehicle-end resource utilization rate. Because the vehicle-end resource utilization rate at the highest risk moment is often greater than that at the lowest risk moment, the minimum MIN (C) in the vehicle-end resource utilization rates L (C1), L (C2), L (C3), \ 8230and L (Cm) at the lowest risk moments in a plurality of operation stages can be determined as the target resource utilization rate, so that the calculation time is saved.
In still other embodiments, the target vehicle-end resource utilization rate includes a vehicle-end resource utilization rate corresponding to the highest risk time and a target vehicle-end resource utilization rate corresponding to the lowest risk time, and the target vehicle-end resource utilization rate may be determined according to the maximum value and the minimum value of the vehicle-end resource utilization rates in the multiple operation stages. For example, the maximum value MAX (C) of the vehicle-end resource utilization rates H (C1), H (C2), H (C3), \8230;, H (Cm) at the time of highest risk in a plurality of operation phases and the minimum value MIN (C) of the vehicle-end resource utilization rates L (C1), L (C2), L (C3), \8230;, L (Cm) at the time of lowest risk in a plurality of operation phases may be determined as the target resource utilization rate.
And step S130, issuing new service according to the comparison result of the target vehicle-end resource utilization rate and a preset utilization rate threshold value.
The preset utilization rate threshold is preset and stored in the vehicle, and may be used for judging the use condition of the vehicle-end resource and the feasibility of service upgrade.
The basic principle of service release in the embodiment of the present application is as follows: under the condition of ensuring the availability of the system, the service requirement of the user is met to the maximum extent, and the utilization resources of the vehicle end are saved to the maximum extent. The following three points can be specifically summarized:
1. and the utilization rate of the vehicle-end resources in each phase of the operation of the service P is always smaller than a preset utilization rate threshold value.
2. Publishing service P may maximize the value of the overall service to the user.
3. The utilization rate of the vehicle end resources is lowest.
Specifically, the target vehicle-side resource utilization rate can be compared with a preset utilization rate threshold, and a new service is issued according to the comparison result, so that the current vehicle-side resource use condition and the service upgrading feasibility can be determined in advance, and whether the new service is issued or not can be decided based on the judgment.
For example, if the target vehicle-side resource utilization rate is MAX (C) and MIN (C), issuing a new service according to a comparison result between the target vehicle-side resource utilization rate and a preset utilization rate threshold includes at least the following three cases:
1) If MIN (C) is greater than or equal to the preset utilization rate threshold value, the three points 1-3 are not met, and no new service is issued to the vehicle end. Alternatively, at this time, the values of the new service and the installed service may be compared, and the installed service having a low value may be replaced with the new service having a high value, that is, the installed service having a low value may be uninstalled, and the new service having a high value may be installed.
2) If MAX (C) is less than or equal to the preset utilization threshold, the above three points are met, and a new service can be released at this time.
3) If the preset utilization rate threshold is greater than MIN (C) and less than MAX (C), a certain resource risk exists when the new service is released, and a vehicle can not respond in time, the service release risk can be further analyzed, and whether the new service is released or not can be determined according to the service release risk.
It should be noted that, for details of the specific implementation of issuing the new service, refer to the following steps S230, S330, and S430-S460, which are not described herein again.
According to the service issuing method, the target vehicle-end resource utilization rate is determined according to the vehicle-end resource utilization rates in multiple operation stages, the new service is issued according to the comparison result of the target vehicle-end resource utilization rate and the preset utilization rate threshold value, the resource use condition and the service upgrading feasibility can be judged in advance, therefore, the user service requirement is met to the maximum extent under the condition that the system is ensured to be available, the vehicle-end utilization resources are saved, and the risk of operation blockage and running rush of the service caused by resource problems is reduced. The embodiment of the application can automatically acquire the optimal combination scheme under the condition of meeting the resource limit, so that the hardware resources of the vehicle machine can be fully utilized. In addition, the embodiment of the application calculates according to the running stage of specific service running, so that the calculation amount can be reduced, and the service release efficiency is improved.
Referring to fig. 3, fig. 3 is a schematic flow chart illustrating a service publishing method according to another embodiment of the present application. The service distribution method may be applied to the service distribution module 130 in the service distribution system 100 shown in fig. 1, or the service distribution apparatus 200 shown in fig. 6, which will be mentioned below, or the vehicle 300 shown in fig. 7, which will be mentioned below. The service publishing method may include the following steps S210-S230.
Step S210, obtaining vehicle end resource utilization rates of the vehicle in multiple operation stages, wherein the multiple operation stages are divided according to the operation state of the vehicle and the vehicle end resource utilization rates.
For the detailed description of step S210, please refer to step S110, which is not described herein again.
Step S220, determining a maximum value of the vehicle-end resource utilization rates of the multiple operation stages as a first target vehicle-end resource utilization rate.
The first target vehicle-end resource utilization rate in the embodiment of the application is the utilization rate corresponding to the highest risk moment, namely, the possibility that the vehicle cannot respond in time or even has the highest possibility of blocking under the first target vehicle-end resource utilization rate is the highest.
For the detailed description of step S220, please refer to step S210, which is not described herein again.
In step S230, if the first target vehicle-end resource utilization rate is less than or equal to the preset utilization rate threshold, it is determined to issue a new service.
And when the utilization rate of the first target vehicle-end resource is less than or equal to the preset utilization rate threshold value, the vehicle-end system is available, and at the moment, new service can be released.
In some embodiments, the new services can be issued in sequence from high value to low value according to the value of the new services, and after each new service is issued, a service issuing process can be executed once to determine whether to issue a next new service, so that normal operation of a vehicle end is ensured, and safety of the vehicle end is improved.
In other embodiments, the current available resources of the system can be calculated according to the resource utilization rate of the first target vehicle end, the target services can be selected from the new services according to the available resources in the sequence from high value to low value of the new services, and the target services are issued to the vehicle end in parallel, so that the service issuing time can be saved.
According to the service issuing method provided by the embodiment of the application, the target vehicle-end resource utilization rate is determined according to the vehicle-end resource utilization rates in multiple operation stages, and the new service is issued according to the comparison result of the target vehicle-end resource utilization rate and the preset utilization rate threshold value, so that the resource use condition and the service upgrading feasibility can be judged in advance, the user service requirement is met to the greatest extent under the condition that the system is ensured to be available, the vehicle-end utilization resources are saved, and the risk of operation jam and running of the service caused by resource problems is reduced.
Referring to fig. 4, fig. 4 is a flowchart illustrating a service publishing method according to another embodiment of the present application. The service distribution method may be applied to the service distribution module 130 in the service distribution system 100 shown in fig. 1, or the service distribution apparatus 200 shown in fig. 6, which will be mentioned below, or the vehicle 300 shown in fig. 7, which will be mentioned below. The service publishing method may include the following steps S310-S330.
Step S310, obtaining vehicle end resource utilization rates of the vehicle in multiple operation stages, wherein the multiple operation stages are divided according to the operation state of the vehicle and the vehicle end resource utilization rates.
For the detailed description of step S310, please refer to step S110, which is not described herein again.
Step S320, determining a minimum value of the vehicle-end resource utilization rates of the multiple operation phases as a second target vehicle-end resource utilization rate.
The second target vehicle-end resource utilization rate in the embodiment of the application is the utilization rate corresponding to the lowest risk moment, namely the possibility that the vehicle cannot respond in time or even is stuck is lowest under the second target vehicle-end resource utilization rate.
For the detailed description of step S320, please refer to step S210, which is not described herein again.
Step S330, if the utilization rate of the second target vehicle-side resource is greater than or equal to the preset utilization rate threshold, determining not to issue the new service or issuing the new service according to the service retention weight, wherein the service retention weight represents the value of the service.
When the resource utilization rate of the second target vehicle end is greater than or equal to the preset utilization rate threshold value, the available resources of the system are less, and at the moment, the new service can be determined not to be issued or issued according to the service reservation weight.
In some embodiments, the step of calculating the service retention weight for each service is as follows: acquiring a sum of a value function of a target service and a value function of all services (namely, installed services or services to be installed), wherein the target service is one of the all services; acquiring a first preset relation function among the resource utilization rate, the operation stage and the time of a target service; acquiring a second preset relation function among the utilization rate of vehicle-side resources, an operation stage and time; and calculating the service retention weight of the target service according to the value function of the target service, the sum of the value functions of all the services, the first preset relation function and the second preset relation function.
In some embodiments, the step of obtaining the cost function of the target service is as follows: acquiring the trigger time of a target service and the trigger times corresponding to the trigger time, and constructing a service utilization function according to the trigger time and the trigger times; acquiring a demand level acquisition time of a target service and a demand level corresponding to the demand level acquisition time, and constructing a service demand level function according to the demand level acquisition time and the demand level, wherein the demand level is determined by a user; and calculating a value function of the target service according to the service utilization function and the service demand function.
For ease of understanding, an example is provided herein for the case of the target service P to illustrate a detailed process of calculating the service retention weights. And counting the triggering times of the service P from zero, and if the user clicks the service P once, triggering the service P once, wherein the triggering times are increased by 1. The change situation of the triggering times corresponding to the triggering time along with the time can be fitted to obtain a service usage degree function a (P, t), wherein a (P, t) represents the accumulated usage times of the user to the service P at the time t, the time t is input into a (P, t), and the service triggering times of the user to the service P at the time t can be predicted. The service usage increase gradient Δ a may be calculated according to the service usage function according to the following expression:
Δa＝[a(P,t1)-a(P,t2)]/(t1-t2)；
