Distributed running system of vehicle-mounted Ethernet and running method

Abstract

The invention discloses a distributed running system of a vehicle-mounted Ethernet and a running method. The running system includes: a hardware layer, which is a controller and transmission equipmentof an Ethernet or another high-speed bus; a protocol layer, which is a communication library based on a distributed architecture, and includes a message framework and a protocol stack; a framework layer, which is services based on the distributed architecture or a multimedia framework; a service layer, which is various services realized on the basis of the distributed architecture; an applicationlayer, which is applications based on the various services; and a security layer, which provides a secure environment for each layer. The system has the advantages that an additional encryption mechanism guarantees secure and reliable communication and business processes; customers are regarded as central goals, and autonomy is achieved; local resources are dynamically merged on final user equipment; rapid innovation and rapid expansion based on a common architecture are realized; and real-time processing and physical information system control are realized.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to an operating system and an operating method based on a vehicle-mounted Ethernet distributed system architecture. Background technique [0002] With the progress and development of the automobile industry, automobile manufacturers and users are gradually no longer satisfied with the improvement of the hardware system of the vehicle's mechanical performance and ride comfort, and gradually began to turn their attention to the intelligent upgrade of automobiles. The ideal intelligent vehicle operation system is a comprehensive system that integrates environmental perception, planning decisions, multi-level assisted driving functions, and intelligent multimedia entertainment systems with an organic whole. It will focus on the use of computer computing and modern sensor systems , information fusion, communication, artificial intelligence and a variety of automatic cont...
