Embodiment Construction

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] The present invention provides a dynamic QoS guarantee mechanism, which is oriented to intelligent driving vehicles and based on a service-oriented architecture, which can ensure that the vehicle network of the vehicle is guaranteed under the circumstances of increased vehicle traffic, coexistence of multiple business types, and variable traffic patterns. QoS guarantee requirements for each service traffic in the Through reasonable resource allocation, while realizing deterministic and low-latency communication of time-sensitive traffic, the communication capability of other traffic is guaranteed, and it can be dynamically adjusted according to business mode and service requirements to achieve certain scalability and flexibility.

Abstract

The invention discloses a service-oriented intelligent vehicle vehicle network QoS guarantee method: topology discovery is performed when the vehicle is started, and parameter import of each node in the vehicle electronic and electrical architecture and vehicle network is completed; service and QoS demand registration is performed; when the application layer subscribes to the service Read QoS requirements; calculate and allocate network resources for subscribed services according to QoS requirements, formulate and issue corresponding forwarding and scheduling policies, and complete static configuration; update nodes and give feedback when QoS requirements are changed or added Node information, while calculating whether the remaining network resources in the network meet the changed or newly added QoS requirements; if so, send the configuration file and establish a connection; if not, renegotiate with the previously configured network resources , if the negotiation is successful, reconfigure the vehicle network resources while sacrificing part of the non-real-time stream, generate the corresponding configuration file to update the network configuration and nodes, and establish a connection; if the negotiation fails, a warning will be issued.

Description

technical field [0001] The invention relates to the technical field of in-vehicle network, in particular to the application of technologies such as QoS guarantee of in-vehicle network and time-sensitive network in the field of intelligent driving vehicles, in particular to a service-oriented intelligent vehicle in-vehicle network QoS guarantee method. Background technique [0002] In recent years, the continuous development of intelligent driving vehicles makes it difficult for the traditional in-vehicle communication network based on CAN (Controller Area Network, Controller Area Network) to meet the increasing demand for in-vehicle network communication. The increase in the number of electronic devices such as sensors, controllers and actuators in vehicles has increased the sharing requirements for data transmission and cross-domain communication of intelligent driving vehicles; at the same time, due to the safety requirements of perception, control and decision-making of in...
