A Comparison of ROS 2 and AUTOSAR Adaptive Platform Against Industry-Elicited Automotive Middleware Requirements

In software-defined vehicles, automotive middleware plays a fundamental role in enabling efficient communication, integration, and coordination among software components. This paper examines how well two of the currently most popular middleware frameworks, ROS 2 Jazzy and AUTOSAR Adaptive Platform R24-11, meet practical requirements elicited from automotive software engineers at one of the major automotive supplier companies, ZF Group. Our objective is to provide insight into an otherwise difficult-to-obtain industrial perspective and support a clearer understanding of priorities in the development and evaluation of middleware for automotive applications.

Efficient Integration of cross platform functions onto service-oriented architectures

The automotive industry is currently undergoing a major transformation with respect to the Electric/Electronic (E/E) and software architecture, driven by a significant increase in the complexity of the technological stack within a vehicle. This complexity acts as a driving force for Software-Defined Vehicles (SDVs) leading to the evolution of the automotive E/E architectures from decentralized configuration comprising multiple Electronic Control Units (ECUs) towards a more integrated configuration comprising a smaller number of ECUs, domain controllers, gateways, and High-Performance Computers (HPCs) [2]. This transition along with several other reasons have resulted in heterogeneous software platforms such as AUTOSAR Classic, AUTOSAR Adaptive, and prototypical frameworks like ROS 2. It is therefore essential to develop applications that are both hardware- and platform/middleware-agnostic to attain development and integration efficiency. This work presents an application development and integration concept to facilitate developing applications as Software as a Product (SaaP), while simultaneously ensuring efficient integration onto multiple software architecture platforms. The concept involves designing applications in a hardware- and software platform-agnostic manner and standardizing application interfaces [6]. It also includes describing the relevant aspects of the application and corresponding middleware in a machine-readable format to aid the integration of developed applications. Additionally, tools are developed to facilitate semi-automation of the development and integration processes. An example application has been developed and integrated onto AUTOSAR Adaptive and ROS 2, demonstrating the applicability of the approach. Finally, metrics are presented to show the efficiency of the overall concept.

A Semi-Automated Corner Case Detection and Evaluation Pipeline

In order to deploy automated vehicles to the public, it has to be proven that the vehicle can safely and robustly handle traffic in many different scenarios. One important component of automated vehicles is the perception system that captures and processes the environment around the vehicle. Perception systems require large datasets for training their deep neural network. Knowing which parts of the data in these datasets describe a corner case is an advantage during training or testing of the network. These corner cases describe situations that are rare and potentially challenging for the network. We propose a pipeline that converts collective expert knowledge descriptions into the extended KI Absicherung ontology. The ontology is used to describe scenes and scenarios that can be mapped to perception datasets. The corner cases can then be extracted from the datasets. In addition, the pipeline enables the evaluation of the detection networks against the extracted corner cases to measure their performance.
