Abstract

A method for controlling a vehicle includes: establishing, by a vehicle controller, a connection between a client and a plurality of servers, the plurality of servers includes a primary server and at least one replica server, the at least one replica server is a replica of the primary server; making, by the vehicle controller, a data request about a given service to the plurality of servers; in response to the data request, receiving reply data from the plurality of servers to the data request via a middleware; fusing, by the middleware, the reply data from the plurality of servers to generate a resulting data; receiving, by the vehicle controller, the resulting data; and controlling, by the client, the vehicle based on the resulting data.

Claims

1. A method, comprising:

establishing, by a vehicle controller of a vehicle, a connection between at least one client and a plurality of servers, the plurality of servers includes a primary server and at least one replica server, the at least one replica server is a replica of the primary server;

making, by the vehicle controller, a data request about a given service to the plurality of servers;

in response to the data request, receiving reply data from the plurality of servers to the data request via a middleware;

fusing, by the vehicle controller, the reply data from the plurality of servers to generate a resulting data via the middleware;

receiving, by the vehicle controller, the resulting data; and

controlling, by the vehicle controller, the vehicle based on the resulting data.

2. The method of claim 1, further comprising generating, by the vehicle controller, a plurality of notifications by the plurality of servers in response to establishing the connection between the at least one client and the plurality of servers.

3. The method of claim 2, further comprising filtering, by the vehicle controller, duplicate notifications from the plurality of notifications generated by the plurality of servers to generate a filtered notification via the middleware.

4. The method of claim 3, further comprising receiving, by the vehicle controller, the filtered notification.

5. The method of claim 4, further comprising registering, by the vehicle controller, a same service of a plurality of services with the middleware.

6. The method of claim 5, further comprising maintaining, by the middleware, a list of instances for the same service of the plurality of services.

7. The method of claim 6, further comprising providing, by the vehicle controller, a fusion strategy to the plurality of servers.

8. The method of claim 7, further comprising providing, by the vehicle controller, a filter strategy to the plurality of servers.

9. The method of claim 8, further comprising activating, by the vehicle controller, an alarm in response to receiving the filtered notification from the middleware.

10. A system, comprising:

a vehicle including a vehicle body and a vehicle controller attached to the vehicle body, wherein the vehicle controller is programmed with a middleware to establish a connection between at least one client and a plurality of servers, the plurality of servers includes a primary server and at least one replica server;

wherein the vehicle controller is programmed to;

establish communication between at least one client and the plurality of servers;

make a data request about a service to the plurality of servers;

in response to the data request, receive reply data from the plurality of servers through the middleware;

fuse, by the middleware, the reply data from the plurality of servers to generate a resulting data; and

controlling, by the vehicle controller, the vehicle based on the resulting data.

11. The system of claim 10, wherein each of the plurality of servers generates a plurality of notifications in response to establishing the connection between the at least one client and the plurality of servers.

12. The system of claim 11, wherein the middleware filters duplicate notifications from the plurality of notifications generated by the plurality of servers to generate a filtered notification.

13. The system of claim 12, wherein the vehicle controller is programmed to receive the filtered notification.

14. The system of claim 13, wherein each of the plurality of servers registers a same service of a plurality of services with the middleware.

15. The system of claim 14, wherein the middleware maintains a list of instances for the same service of the plurality of services.

16. The system of claim 15, wherein the vehicle controller is programmed to provide a fusion strategy to the plurality of servers.

17. The system of claim 16, wherein the vehicle controller is programmed to provide a filter strategy to the plurality of servers.

18. The system of claim 17, wherein the vehicle controller is programmed to activate an alarm in response to receiving the filtered notification from the middleware.

19. A system, comprising:

a vehicle including a vehicle body and a vehicle controller attached to the vehicle body, wherein the vehicle controller is programmed with a middleware to establish a connection between at least one client and a plurality of servers;

wherein the vehicle controller is programmed to;

establish the connection between the at least one client and a plurality of servers;

make a data request about a service to the plurality of servers;

in response to the data request, receive reply data from the plurality of servers via the middleware;

fuse, by the middleware, the reply data from the plurality of servers to generate a resulting data;

receive the resulting data;

control the vehicle based on the resulting data;

wherein each of the plurality of servers generates a plurality of notifications in response to establishing the connection between the at least one client and the plurality of servers;

wherein the middleware filters duplicate notifications from the plurality of notifications generated by the plurality of servers to generate a filtered notification;

wherein the vehicle controller is programmed to receive the filtered notification;

wherein each of the plurality of servers registers a same service of a plurality of services with the middleware;

wherein the middleware maintains a list of instances for the same service of the plurality of services;

wherein the vehicle controller is programmed to provide a fusion strategy to the plurality of servers;

wherein the vehicle controller is programmed to provide a filter strategy to the plurality of servers; and

wherein the vehicle controller is programmed to activate an alarm in response to receiving the filtered notification from the middleware.
