Detailed Description
In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a schematic diagram of an application scenario of a service publishing method according to an exemplary embodiment of the present application. The service distribution system 100 includes a data acquisition module 110, a data reporting module 120, and a service distribution module 130. The data acquisition module 110 is used for acquiring vehicle-end data, such as speed, acceleration and ignition signals of a 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 determine a service issuing scheme according to the received vehicle-end data, and execute a service issuing operation. The data acquisition module 110, the data reporting module 120, and the service distribution module 130 are disposed on the same vehicle.
Referring to fig. 2, fig. 2 is a flowchart of a service publishing method according to an 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 described above, 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 distribution method may include the following steps S110 to S130.
Step S110, obtaining the utilization rate of vehicle end resources of the vehicle in a plurality of operation stages, wherein the operation stages are divided according to the operation states of the vehicle and the utilization rate of the vehicle end resources.
The operating phases refer to a plurality of phases of the vehicle during running. The plurality of operating phases may include, but are not limited to, a start phase, a sleep phase, an acceleration driving phase, and a smooth running phase. The plurality of operation phases may be predetermined before the service release is started, or may be determined in the service release flow.
The vehicle-end resource utilization rate refers to the current utilization rate of all hardware resources of the vehicle end, namely the ratio of the occupation amount of all hardware resources of the vehicle end to the total amount. One operation phase may correspond to at least two vehicle-side resource utilization rates. For example, the vehicle-end resource utilization corresponding to the highest risk time and the vehicle-end resource utilization corresponding to the lowest risk time.
In some embodiments, the dividing of the plurality of operational phases is as follows: acquiring the running state, the utilization rate of vehicle end resources, an ignition signal, a speed signal and an acceleration signal of a vehicle; 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 the working condition of the vehicle during running. For example, in terms of the movement pattern of the vehicle, the running state of the vehicle may include, but is not limited to, starting, accelerating, constant speed, decelerating, turning, ascending and descending a slope, and stopping. In terms of the control mode employed by the driver, the operating state of the vehicle may include, but is not limited to, shift speed, coasting (e.g., out-of-gear coasting, neutral coasting, accelerating coasting, parking coasting), braking (e.g., emergency braking, speed control braking, braking), throttle control, steering, and reversing.
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 steps of dividing the plurality of operational phases according to the operational state, the vehicle end resource utilization, the ignition signal, the speed signal, and the acceleration signal are 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 abrupt points, the ignition signals, the speed signals and the acceleration signals; and acquiring service running time, matching the service running time with the time corresponding to the plurality of running phases, and determining service sequences corresponding to the plurality of running phases.
Because the abrupt change of the vehicle-end resource utilization rate is caused by the change of the operation stage, the abrupt change point of the resource utilization rate can be identified according to the operation state and the vehicle-end resource utilization rate, and then the operation stage is divided according to the abrupt change point of the resource utilization rate, an ignition signal, a speed signal and an acceleration signal. After the operation phases are divided, the service and the time corresponding to the operation phases can be matched according to the service operation time so as to determine the service sequence corresponding to each operation phase, and therefore the utilization rate of the vehicle-end resources corresponding to each operation phase can be calculated according to the resources occupied by the service sequence corresponding to each operation phase.
After the operation phases are determined, service sequences corresponding to the operation phases can be obtained, and the utilization rate of vehicle resources of the vehicle in the operation phases is calculated according to the service sequences corresponding to the operation phases.
In some embodiments, the first preset relationship function between the resource utilization of the service P, the operating phase of the vehicle, and the time may be represented as X (C, T, P), where X represents the resource utilization of the service, C represents the operating phase of the vehicle, and T represents the time. The second preset relationship function between the vehicle end resource utilization, the operation phase of the vehicle, and the time may be expressed as Q (C, T, P1, P2, …, pn), where Q represents the vehicle end resource utilization, C represents the operation phase of the vehicle, T represents the time, and P1-Pn represents the service that all users have installed or are about to install. The function analysis formula of the second preset relation function λq (C, T, P1, P2, …, 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. Note that n and m to be mentioned next in the embodiments of the present application are positive integers.
As an example, the service P1 is triggered at times T1, T2 and T3 of the operation stage C, and the resource utilization of the vehicle end and the resource utilization of the service corresponding to times T1, T2 and T3 may be recorded as shown in table 1.
TABLE 1
According to the service sequences corresponding to the operation phases, 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 operation phases can be calculated. The highest risk time refers to the time when the possibility that the vehicle cannot respond to even the jam problem in time is maximum, and the utilization rate of vehicle-end resources is generally higher at the moment. The lowest risk time refers to the time when the possibility that the vehicle cannot respond to even the jam problem in time is minimum, and the utilization rate of vehicle-end resources is low at the moment generally.
In some embodiments, calculating the vehicle-side resource utilization at the highest risk moment for each operational phase includes the steps of: and calculating the sum of the highest utilization rate of the resources of the service P and the highest utilization rate of the resources of other services as the vehicle-end resource utilization rate at the highest risk moment, wherein the service P is any installed or to-be-installed service.
For example, the service P operates in the operating phases C1, C2, …, cm of the vehicle. At time T1 of the Ci operation phase, the resource utilization of 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 T2 of the Ci operation stage, the highest resource utilization rate of other services is Q (Ci, T2, P1, P2, …, pn) -X (Ci, T2, P1), and then the vehicle end resource utilization rate H (Ci) at the time of the highest risk of the Ci operation stage 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-side resource utilization at the lowest risk moment of each operational phase includes the steps of: and calculating the sum of the minimum utilization rate of the resources of the service P and the minimum utilization rate of the resources of other services, and taking the sum as the vehicle-end resource utilization rate at the lowest risk moment. Where service P is any installed or to be installed service.
For example, at time T3 of the Ci operation phase, the resource utilization of service P is at a minimum X (Ci, T3, P), where i is less than or equal to m and greater than or equal to 1. At the time T4 of the Ci operation stage, the resource utilization rate of the service P is Q (Ci, T4, P1, P2, …, pn) -X (Ci, T4, P1) at the lowest resource utilization rate of other services, and the vehicle-end resource utilization rate L (Ci) at the lowest risk time of 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 rate of the plurality of operation stages can be calculated and obtained, wherein the vehicle-end resource utilization rate of the plurality of operation stages comprises the vehicle-end resource utilization rate of the highest risk moment of the plurality of operation stages and the vehicle-end resource utilization rate of the lowest risk moment of the plurality of operation stages. For example, the utilization of the vehicle-end resources at the highest risk time of the plurality of operation phases is H (C1), H (C2), H (C3), …, H (Cm). The utilization rate of the vehicle-end resources at the lowest risk moment of a plurality of operation stages is L (C1), L (C2), L (C3), … and L (Cm).
Step S120, determining the target vehicle-end resource utilization according to the vehicle-end resource utilization of 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 rates of the plurality of operation phases, the target vehicle end resource utilization rate can be determined from the vehicle end resource utilization rates of the plurality of operation phases.
In some embodiments, the target vehicle-end resource utilization is a vehicle-end resource utilization corresponding to the highest risk moment, and a maximum value of the vehicle-end resource utilization in the multiple operation phases may be determined as the target vehicle-end resource utilization. For example, the maximum value of all of the vehicle-end resource utilization rates H (C1), H (C2), H (C3), …, H (Cm), and L (C1), L (C2), L (C3), …, L (Cm) may be determined as the target vehicle-end resource utilization rate. Because the utilization rate of the vehicle-end resource at the highest risk moment is often greater than that at the lowest risk moment, the maximum value MAX (C) of the utilization rates H (C1), H (C2), H (C3), …, H (Cm) of the vehicle-end resource at the highest risk moment in a plurality of operation phases can be determined as the target utilization rate, so as to save the calculation time.
In other embodiments, the target vehicle resource utilization is a vehicle-end resource utilization corresponding to the lowest risk moment, and the minimum value of the vehicle-end resource utilization in the multiple operation phases may be determined as the target vehicle-end resource utilization. For example, the minimum value of all of the vehicle-end resource utilization rates H (C1), H (C2), H (C3), …, H (Cm), and L (C1), L (C2), L (C3), …, and L (Cm) may be determined as the target vehicle-end resource utilization rate. Since the utilization rate of the vehicle-end resource at the highest risk moment is often greater than that at the lowest risk moment, the minimum value MIN (C) in the vehicle-end resource utilization rates L (C1), L (C2), L (C3), …, L (Cm) at the lowest risk moment in a plurality of operation phases can be determined as the target resource utilization rate, so as to save the calculation time.
In still other embodiments, the target vehicle-end resource utilization rate includes a vehicle-end resource utilization rate corresponding to a highest risk time and a target vehicle-end resource utilization rate corresponding to a lowest risk time, and the maximum value and the minimum value in the vehicle-end resource utilization rates in the multiple operation phases may be determined to be the target vehicle-end resource utilization rate. For example, the maximum value MAX (C) of the highest risk timings of the plurality of operation phases, H (C1), H (C2), H (C3), …, H (Cm) and the minimum value MIN (C) of the lowest risk timings of the plurality of operation phases, L (C1), L (C2), L (C3), …, L (Cm) may be determined as the target resource utilization.
Step S130, a new service is issued according to the comparison result of the target vehicle-end resource utilization and the preset utilization threshold.
The preset utilization threshold is preset and stored in the vehicle, and can be used for judging the utilization condition of the vehicle-end resources and the feasibility of service upgrading.
The basic principle of service release in the embodiment of the application is as follows: under the condition of ensuring the availability of the system, the service requirement of the user is met to the greatest extent, and the utilization resources of the vehicle end are saved to the greatest extent. Specifically, the following three points can be adopted for generalization:
1. the utilization rate of the vehicle-end resources at each stage of service P operation is always smaller than a preset utilization rate threshold value.
2. The publication service P may maximize the value of the overall service to the user.
3. The utilization rate of the vehicle-end resources is the lowest.
Specifically, the target vehicle-end resource utilization rate can be compared with a preset utilization rate threshold value, and a new service is issued according to the comparison result, so that the current vehicle-end resource utilization condition and service upgrading feasibility can be determined in advance, and whether to issue the new service is decided based on the judgment.
For example, if the target vehicle-end resource utilization is MAX (C) and MIN (C), the issuing of the new service according to the comparison result between the target vehicle-end resource utilization and the preset utilization threshold value at least includes the following three cases:
1) If MIN (C) is larger than or equal to the preset utilization rate threshold, the three points 1-3 are not met, and at the moment, no new service is issued to the vehicle end. Alternatively, the value of the new service and the value of the installed service may be compared at this time, 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 smaller than or equal to the preset utilization threshold, the three points are met, and at the moment, new service can be released.
3) If the preset utilization rate threshold is larger than MIN (C) and smaller than MAX (C), a certain resource risk exists in the process of releasing the new service, and the vehicle can possibly fail to respond in time, the service release risk can be further analyzed, and whether to release the new service is determined according to the service release risk.
It should be noted that, the details of the implementation of the new service release are shown in the following steps S230, S330 and S430-S460, which are not described herein.
According to the service release 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 of a plurality of operation stages, and the new service is released 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 service requirements of users can be met to the greatest extent under the condition that the availability of a system is ensured, the vehicle-end utilization resources are saved, and the running jam and running burst risks caused by the resource problem of the service are reduced. According to the method and the device for obtaining the optimal combination scheme, under the condition that the resource limitation is met, the optimal combination scheme can be automatically obtained, and therefore vehicle hardware resources can be fully utilized. In addition, the embodiment of the application calculates aiming at the operation stage of the specific service operation, so that the calculated amount can be reduced, and the service release efficiency is improved.
Referring to fig. 3, fig. 3 is a flowchart of 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 described above, 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 distribution method may include the following steps S210 to S230.
Step S210, obtaining the utilization rate of vehicle end resources of the vehicle in a plurality of operation stages, wherein the operation stages are divided according to the operation states of the vehicle and the utilization rate of the vehicle end resources.
The specific description of step S210 is referred to the aforementioned step S110, and will not be repeated here.
Step S220, determining the maximum value of the vehicle-end resource utilization rates in a plurality of operation phases 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 is blocked under the first target vehicle-end resource utilization rate is highest.
The specific description of step S220 is referred to the aforementioned step S210, and will not be repeated here.
Step S230, if the first target vehicle end resource utilization is smaller than or equal to the preset utilization threshold, the new service release is determined.
When the utilization rate of the first target vehicle-end resource is smaller than or equal to a preset utilization rate threshold value, the vehicle-end system is available, and at the moment, a new service can be released.
In some embodiments, the new service may be sequentially released according to the value of the new service from high to low, and after each release of the new service, a service release process may be executed to determine whether to release the next new service, so as to ensure normal operation of the vehicle end and improve safety of the vehicle end.
In other embodiments, the current available resources of the system can be calculated according to the first target vehicle-end resource utilization rate, the target service can be selected from the new service according to the available resources from high to low according to the value of the new service, and the target service can be issued to the vehicle end in parallel, so that the service issuing time can be saved.
According to the service release 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 of a plurality of operation stages, and the new service is released 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 service requirements of users can be met to the greatest extent under the condition that the availability of a system is ensured, the vehicle-end utilization resources are saved, and the running jam and running burst risks caused by the resource problem of the service are reduced.
Referring to fig. 4, fig. 4 is a flowchart of 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 described above, 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 distribution method may include the following steps S310 to S330.
Step S310, obtaining the utilization rate of the vehicle end resources of the vehicle in a plurality of operation stages, wherein the operation stages are divided according to the operation states of the vehicle and the utilization rate of the vehicle end resources.
The specific description of step S310 is referred to the aforementioned step S110, and will not be repeated here.
Step S320, determining the minimum value of the vehicle-end resource utilization rates in the multiple operation phases as the 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 under the second target vehicle-end resource utilization rate is lowest.
The specific description of step S320 is referred to the aforementioned step S210, and will not be repeated here.
Step S330, if the second target vehicle-end resource utilization is greater than or equal to the preset utilization threshold, it is determined that no new service is issued or that a new service is issued according to a service reservation weight, and the service reservation weight characterizes 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, the available resources of the system are less, and at the moment, it can be determined that no new service is released or that the new service is released according to the service reservation weight.
In some embodiments, the service reservation weight for each service is calculated as follows: obtaining a sum of a cost function of a target service and a cost function of all services (i.e., installed services or services to be installed), wherein the target service is one of all services; acquiring a first preset relation function among the resource utilization rate, the operation stage and the time of the target service; acquiring a second preset relation function among the utilization rate of the vehicle-end resources, the operation stage and the time; and calculating the service reservation weight of the target service according to the cost function of the target service, the sum of the cost functions of all the services, the first preset relation function and the second preset relation function.
In some embodiments, the step of obtaining a cost function for the target service is as follows: acquiring the trigger time of the target service and the trigger times corresponding to the trigger time, and constructing a service usage degree 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 cost function of the target service according to the service usage degree function and the service demand degree function.
For ease of understanding, an example is provided herein to illustrate a detailed process of calculating service reservation weights taking the target service as service P. The triggering times of the service P are counted from zero, and the user clicks the service P once, so that the service P is triggered once, and the triggering times are increased by 1. The method can fit the time-dependent change of the triggering times corresponding to the triggering time to obtain a service usage degree function a (P, t), wherein a (P, t) represents the accumulated usage times of the user on the service P at the time t, the time t is input into the a (P, t), and the service triggering times of the user on the service P at the time t can be predicted. The service usage ascending gradient Δa may be calculated according to the following expression from the service usage function:
Δa＝[a(P,t1)-a(P,t2)]/(t1-t2)；
the greater the gradient of the increase in the service usage, the faster the user's increase in the service P.
The service P may be set to have a demand level of five stars, which indicates that the user has a higher demand for the service P when the user marks five stars for the service P, and sequentially decreases, and indicates that the user has a lowest demand for the service P when the user marks one star for the service P. The demand level acquisition time of the service P and the demand level corresponding to the demand level acquisition time can be acquired, the change condition of the demand level corresponding to the demand level acquisition time of the service P along with time is fitted, a service demand level function b (P, t) is obtained, b (P, t) represents the demand level of a user on the service P at the time t, the time t is input into the b (P, t), and the service demand level of the user on the service P at the time t can be predicted. The service demand level gradient Δb may be calculated from the service demand level function according to the following expression:
Δb＝[b(P,t1)-b(P,t2)]/(t1-t2)；
