混合临界车载网络的仿真

Simulation of Mixed Critical In-vehicular Networks

Philipp Meyer, Franz Korf, Till Steinbach, Thomas C. Schmidt

摘要:

从高级驾驶员辅助到自动驾驶的未来汽车应用将大大增加对车载网络的需求。高带宽或低延迟要求的数据流,特别是许多额外的通信关系将给车内通信系统引入新的复杂度。预计未来将传感器和执行器与汽车ECU互连的通信主干将建立在以太网技术之上。然而,来自不同应用域的信令需要定制属性的网络服务,包括在TSN以太网扩展中定义的实时传输协议。这些QoS约束将进一步增加网络复杂性。基于事件的仿真是解决车载网络设计难题的关键技术。本章介绍车载网络的特定领域和仿真模型,并概述以汽车为中心的网络设计过程。从特定领域的描述语言开始,我们涵盖了相应的仿真模型及其工作流程,并将我们的方法应用于高级汽车车载网络的相关案例研究。

英文摘要:

Future automotive applications ranging from advanced driver assistance to autonomous driving will largely increase demands on in-vehicular networks. Data flows of high bandwidth or low latency requirements, but in particular many additional communication relations will introduce a new level of complexity to the in-car communication system. It is expected that future communication backbones which interconnect sensors and actuators with ECU in cars will be built on Ethernet technologies. However, signalling from different application domains demands for network services of tailored attributes, including real-time transmission protocols as defined in the TSN Ethernet extensions. These QoS constraints will increase network complexity even further. Event-based simulation is a key technology to master the challenges of an in-car network design. This chapter introduces the domain-specific aspects and simulation models for in-vehicular networks and presents an overview of the car-centric network design process. Starting from a domain specific description language, we cover the corresponding simulation models with their workflows and apply our approach to a related case study for an in-car network of a premium car.
