[0054] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0055] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0056] In the vehicle-machine interconnection solution, currently, business components such as services and applications based on the vehicle operating system process can only be allocated to the vehicle-machine side or the user side during the development phase. Once the compilation and packaging are completed and the components are flashed to the hardware, they can no longer be adjusted according to the load. It can be seen that this allocation result is fixed and cannot be adjusted. Therefore, there is no solution for load balancing business components between the vehicle-machine side and the user side. In response to the above-mentioned load balancing problem, the embodiments of the present disclosure provide a load balancing method, device, medium, equipment and vehicle for vehicle-machine interconnection. For ease of understanding, the embodiments of the present disclosure are described below.

[0057] The disclosed embodiment provides a load balancing method for vehicle-machine interconnection, which can dynamically load balance the service components between the vehicle-machine end and the user end according to the load on the vehicle-machine end and the user end; the technology can be applied to autonomous driving vehicles and manned vehicles. The method can be executed by a load balancing device for vehicle-machine interconnection, and the load balancing device for vehicle-machine interconnection can be implemented in software and / or hardware.

[0058] To facilitate understanding of the disclosed embodiments, the application scenario of the load balancing method for vehicle-machine interconnection is first described. Vehicle-machine interconnection refers to connecting the vehicle-machine end with a user end such as a mobile phone, tablet, smart watch, etc. through a connection method such as Ethernet, CarPlay, and a data cable, so that the user can directly access the application (such as map, information, music, etc.) on the user end from the screen of the vehicle-machine end, or vice versa, access the application on the vehicle-machine end from the user end.

[0059] In one example, if Figure 1As shown, the vehicle terminal can be a terminal of a vehicle deployed with the Android Automotive OS system. Android Automotive is an Android platform for cars. The full name of OS is Operating System, which means operating system. The user terminal can be a terminal deployed with a car service framework, such as a common mobile phone. The vehicle terminal and the user terminal can be connected via Ethernet, and there can be at least one user terminal connected to the same vehicle terminal.

[0060] In order to facilitate the implementation of the load balancing method for vehicle-machine interconnection, this embodiment can determine a master server from the vehicle-machine end and the user end that establish the connection, and other terminals except the master server are slave servers. For example, the vehicle-machine end is determined as the master server, and the user end is determined as the slave server.

[0061] According to the above embodiments, the load balancing method for vehicle-machine interconnection provided in this embodiment can be applied to the main server, and the main server is one of the vehicle-machine end and the user end that establish the connection. Figure 2 As shown, the method may include the following steps:

[0062] Step S102, obtaining the service components deployed simultaneously on the vehicle machine side and the user side with which the connection has been established.

[0063] Some of the same business components are deployed on the vehicle side and the user side, and these same business components can be load balanced. Figure 3 In the example, the business components include services and applications, and the same services 1, 2, 3, and 4, as well as applications 1, 2, 3, and 4 are deployed on the vehicle side and the user side. In this embodiment, redundant backup of business components is performed on the vehicle side and the user side, which can improve service robustness and provide basic support for subsequent load balancing.

[0064] This embodiment obtains the above-mentioned business components deployed simultaneously on the vehicle terminal and the user terminal through the main server terminal, that is, obtains the above-mentioned business components deployed simultaneously on the main server terminal and the slave server terminal.

[0065] Reference Figure 4 , load balancing services are also deployed in the vehicle side and the user side. The load balancing service on the vehicle side establishes a connection and communicates with the load balancing service on the user side through Ethernet. The load balancing service is used to detect the load situation of the current terminal, and manage the business components such as enabling, stopping, and prohibiting according to the load situation to achieve load balancing. Taking the vehicle side as an example, the load balancing service can specifically be the control interface responsible for monitoring and managing business components in the vehicle side.

[0066] In this embodiment, the master-slave relationship between the vehicle terminal and the user terminal can also be understood as the master-slave relationship between the load balancing service of the vehicle terminal and the load balancing service of the user terminal. For example, the master service terminal is the vehicle terminal, which is equivalent to the master service terminal being the load balancing server of the vehicle terminal, and correspondingly, the slave service terminal is the load balancing server of the user terminal.

[0067] Step S104, obtaining the master load of the master server and receiving the slave load sent by the slave server, wherein the master server is one of the vehicle terminal and the user terminal, and the slave server is the terminal other than the vehicle terminal and the user terminal.

[0068] In this embodiment, the main server collects at least one load indicator of itself at a preset time interval, and obtains the main end load according to each load indicator. Load indicators include, but are not limited to: the number of enabled business components, the proportion of enabled business components to all business components, CPU utilization, memory utilization, disk utilization and network card bandwidth, etc.; the main end load is determined based on the above-mentioned load indicators collected and the weights assigned to each load indicator. In some examples, the number of enabled business components can be determined as the main end load. Alternatively, the main end load is determined according to x=αK1+βK2+γK3, where x represents the main end load, K1, K2, and K3 respectively represent the proportion of enabled business components to all business components, CPU utilization, and memory utilization, and α, β, and γ are the weights of K1, K2, and K3 respectively. Of course, the above is only an example of the main end load and should not be understood as a limitation.

[0069] And, the slave server collects at least one load indicator of itself according to the above preset time interval, obtains the slave load (which can be expressed as y) according to each load indicator, and sends the slave load y to the master server. The process of obtaining the slave load from the slave server can refer to the above embodiment of the master load, and will not be described in detail here.

[0070] Step S106, monitoring whether the load on the master end and the load on the slave end within a preset time period meet a load balancing condition.

[0071] In this embodiment, it can be determined whether load balancing is required based on the load on the master end and the load on the slave end, wherein there can be multiple load balancing conditions, such as referring to the following embodiments.

[0072] In some embodiments, the load balancing condition may include: any load is greater than a preset first load value. In this case, monitor the master-side load or the slave-side load within a preset time period to see if one of them is greater than the preset first load value. If so, it means that one of the master server and the slave server is overloaded, and the load between the master server and the slave server is unbalanced, and load balancing is required to determine whether the load balancing condition is met; at the same time, determine the current load that is greater than the first load value. Taking the current load that exceeds the first load value as the master-side load as an example, the master-side load is greater than the first load value, which means that the master server is overloaded and some business components on the master server need to be allocated to the slave server.

[0073] In some embodiments, the load balancing condition may include: any load is less than a preset second load value. In this case, monitor the master-side load or the slave-side load within a preset time period to see if one of them is less than the preset second load value. If so, it means that one of the master server and the slave server has more idle computing resources and can assist the other in running business components, thereby determining that the load balancing condition is met; at the same time, determine the current load that is less than the second load value. Taking the current load that is less than the second load value as the master-side load as an example, the master-side load is less than the second load value, which means that the master server has excess computing resources, and some of the business components on the slave server can be allocated to the master server to assist the slave server in running the business components more smoothly.

[0074] In some embodiments, the load balancing condition may include: the load difference between the master end load and the slave end load is greater than a preset threshold. In this scenario, an embodiment of monitoring whether the master end load and the slave end load within a preset time period meet the load balancing condition may include:

[0075] The load difference between the master end load and the slave end load is determined at a preset time interval. Specifically, the master end load x and the slave end load y are differentiated to obtain the load difference δ, δ=xy.

[0076] Monitor whether the absolute value of the average value of multiple load differences within a preset time period is greater than a preset threshold; the preset time period includes multiple preset time intervals. When implemented, the average value of multiple load differences δ within the preset time period can be calculated. Then the average The absolute value of Compare with the preset threshold t.

[0077] If the absolute value of the average of multiple load differences If the average value of the load difference is greater than the preset threshold value t, it means that there is a load imbalance between the master server and the slave server and it lasts for a period of time, and load balancing is required. Therefore, when the absolute value of the average value of the load difference is greater than the preset threshold value, it is determined that the load balancing condition is met.

[0078] If the absolute value of the average of multiple load differences If it is not greater than the preset threshold t, it means that there is no load imbalance between the master server and the slave server, or the load imbalance only occurs briefly. At this time, load balancing is not required, and the load balancing condition is not met.

[0079] This embodiment can determine which of the master server and the slave server is overloaded based on the positive and negative values ​​of the average values ​​of the multiple load differences, and then load balance the enabled service components on the master server and the slave server.

[0080] Step S108: When the load balancing condition is met, load balancing is performed on the enabled service components on the master server and the slave server.

[0081] According to the above embodiment, when it is determined that the load balancing condition is met, the enabled service components on the master server and the slave server can be load balanced according to the master load and the slave load. In this embodiment, the master load and the slave load are first compared, and then the load balancing embodiment is described according to the two situations that the master load is greater than the slave load, or the slave load is greater than the master load.

[0082] In this embodiment, when the load on the master end is greater than the load on the slave end, at least one first service component to be balanced is selected from the service components enabled on the master server. Service components can generally include two states: enabled and disabled. The same service component is generally enabled on only one terminal. Figure 5 As shown, all the services and applications that can be load balanced in the vehicle are enabled on the vehicle side and disabled on the user side.

[0083] In the implementation process of selecting the first business component, at least one first business component to be balanced can be selected from the business components enabled on the main server according to preset selection indicators; wherein the selection indicators include at least one of the following: arrangement order of the business components, resource occupancy, importance level and usage frequency, etc.

[0084] In one example, among the enabled service components on the primary server, the first two service components, namely, service 1 and service 2, are selected as the first service components to be balanced according to the arrangement order of the service components.

[0085] Then, the first service component is transferred from the master server to the slave server for operation.

[0086] In a specific embodiment, the master server sends the first component identifier of the first service component to the slave server, so that the slave server controls the first service component to enter a waiting-for-balancing state according to the first component identifier.

[0087] In order to more intuitively show the user which first business components are being transferred, in this embodiment, before the master server sends the first component identifier of the first business component to the slave server, the master server can first control the display mode of the first business component on the display interface to change, so as to prompt the first business component to enter the waiting state from the enabled state through the changed display mode. Figure 6 As shown, the first business component can change the original solid-line frame display mode to a dotted-line frame display mode, and the changed dotted-line frame display mode prompts the first business component to enter the waiting state from the enabled state, and the first business component is disabled on the main server at this time. The above display mode changes are only examples, and there can be many other practical applications, such as changing the control display mode from color to gray.

[0088] Similarly, after the slave server controls the first service component to enter the waiting state, it can also control the first service component to change its display mode on the display interface of the slave server, so as to prompt the first service component to enter the waiting state from the disabled state through the changed display mode.

[0089] After the slave server controls the first service component to enter the waiting state, it will feedback a notification to the master server. When the master server receives the notification from the slave server that the first service component has entered the waiting state, it controls the first service component to stop running and enter the disabled state; and sends a notification to the slave server that the first service component has entered the disabled state, so that the slave server starts running the first service component.

[0090] At this point, the load balancing between the master server and the slave server is completed; then, continue to obtain the master load and receive the slave load, monitor whether the master load and the slave load within the preset time meet the load balancing conditions, and if so, load balance the enabled business components on the master server and the slave server.

[0091] In this embodiment, when the load on the slave end is greater than that on the master end, at least one second service component to be balanced is selected from the service components enabled on the slave end, and the second service component is transferred from the slave end to the master end for operation.

[0092] The implementation process of this embodiment is basically the same as the above embodiment. Specifically, it includes: among the enabled business components on the slave server, at least one second business component to be balanced is selected according to a preset selection index. The slave server controls the display mode of the second business component to change on the display interface, so as to prompt the second business component to enter the state to be balanced from the enabled state through the changed display mode. The slave server sends the second component identifier of the second business component to the master server, and the master server controls the second business component to enter the state to be balanced according to the second component identifier, and feeds back a notification to the slave server that the second business component has entered the state to be balanced. The slave server controls the second business component to stop running and enter the disabled state, and sends a notification to the master server that the second business component has entered the disabled state. The master server starts running the second business component.

[0093] In one embodiment, a method for determining a master server and a slave server between a vehicle terminal and a user terminal may also be provided, as shown below.

[0094] A connection is established between the vehicle terminal and the user terminal; after the connection is established, a master server terminal and a slave server terminal are determined from the vehicle terminal and the user terminal according to the following two implementation methods.

[0095] Implementation method 1. After the connection is established, the master server and the slave server are determined from the vehicle terminal and the user terminal according to the preset master-slave relationship. Considering that the vehicle terminal is generally fixed and the number is generally one, while the user terminal may change frequently and the number is not fixed, the vehicle terminal can be preset as the dominant and the user terminal as the subordinate; according to the master-slave relationship, the vehicle terminal is determined as the master server from the vehicle terminal and at least one user terminal, and the other user terminals are slave servers. This embodiment uses the master-slave relationship to quickly determine the master server and the slave server.

[0096] Implementation method 2. Both the vehicle terminal and the user terminal are used as terminals to be elected. The load score of each terminal to be elected is determined according to the preset load index, and the highest load score is determined from the load scores of all terminals to be elected. The load index is the performance information of the service that each terminal to be elected will collect regularly after startup. The load index can include multiple indicators such as CPU utilization, available memory, network bandwidth, disk utilization, etc. The corresponding load score is calculated according to the load index and its preset weight. The higher the load score, the better the performance of the terminal to be elected. The terminal to be elected corresponding to the highest load score is determined as the main server, and the terminals to be elected other than the main server are determined as slave servers.

[0097] This embodiment first calculates the load score according to the load index, and then uses the load score to determine the master server and the slave server. This can increase the possibility of using a high-performance terminal as the master server, thereby improving the load balancing efficiency between the vehicle terminal and the user terminal.

[0098] In summary, the load balancing method for vehicle-machine interconnection provided by the present disclosure includes, first, obtaining the service components deployed simultaneously on the vehicle-machine end and the user end with established connection; and, obtaining the master-end load of the master server end, receiving the slave-end load sent by the slave server end; and then monitoring whether the master-end load and the slave-end load within the preset time length meet the load balancing condition; when the load balancing condition is met, load balancing is performed on the service components enabled on the master server end and the slave server end. It can be seen that, by obtaining the service components deployed simultaneously on the vehicle-machine end and the user end, the technical scheme provides basic support for adjusting the distribution relationship between the service components and the terminals (i.e., the vehicle-machine end and the user end), and then, when it is monitored that the master-end load and the slave-end load meet the load balancing condition, the service components on the vehicle-machine end and the user end can be load balanced, so that the situation that some terminals are highly loaded and some terminals are idle can be prevented, the utilization efficiency of the hardware computing power is improved, the reliability and robustness of the service components running between the vehicle-machine end and the user end are improved, and the probability of service unavailability is reduced.
