A car intelligent infotainment service system and its control method

Abstract

The present invention provides an automobile intelligent infotainment service system, which digitally processes intelligent information including entertainment information, and realizes distributed deployment with a man-machine interface client, which at least includes mutually separated: automobile Ethernet intelligent interconnection antenna A controller, which includes an antenna and a functional module, a central processing unit, and an Ethernet communication interface; and, a man-machine interface client, which includes an operation interaction module, an arithmetic processing unit, and an Ethernet communication interface; wherein, the man-machine interface The client and the automotive Ethernet intelligent interconnection antenna controller are based on the distributed architecture design to realize mutual communication through the Ethernet communication interface. The technical solution of the present invention highlights the independence of the infotainment functional domain and avoids system complexity and redundancy; more reasonably Deploy interconnection and communication function modules in the car; continue to use the function and performance advantages of its roof antenna digital gateway; serve more than two or more man-machine interface windows in the car, and the software angle can be reasonably realized; isolation Separate isolation and deployment of functional applications with relatively large security vulnerabilities in communication and interconnection can reduce the impact on systems with high security levels in the car, etc.

Description

technical field [0001] The invention relates to vehicle Ethernet technology, in particular to a distributed vehicle information service system and its corresponding control method. Background technique [0002] Traditional vehicle infotainment systems generally include the human-machine interface, navigation, radio, multimedia player, and device interconnection focused on the central control system, as well as some body control functions (such as air conditioning control, volume control, etc.), and some vehicle status information. real-time display. Definition of a broader category: The vehicle infotainment system also includes the processing and display of some assisted driving function information, the access of network communication and car phone, and the integration of voice recognition, etc. Generally speaking, the conventional vehicle-mounted central control infotainment system in the prior art is a centralized system. [0003] Since the traditional vehicle central c...

Problems solved by technology

Of course, since all functions are concentrated on the only screen, the entire operating system is very complicated and subject to the technical characteristics of the centralized system, which also greatly limits the flexible planning and deployment of in-vehicle interconnection and communication functions

When there are more than two human-machine interface requirements in the car, the realization of the existing system technology is more complicated and difficult; at the same time, because it is a centralized system, the security loopholes are relatively large; especially for interconnection and high-level security functions When systems such as auxiliary driving functions coexist, there are relatively high safety hazards

[0004] In order to solve the complex operation of the centralized central control system in the prior art, the flexible deployment of interconnection and communication functions in the vehicle is limited; when there are more than two human-machine interface requirements, it is difficult to implement and the system requires high levels of interconnection and safety functions For example, when auxiliary driving functions and other functions coexist, there are defects such as relatively high potential safety hazards; the present invention proposes a new distributed vehicle information service system and its corresponding control method
