Automated Dynamic Safety Evaluation of Generic Fail-Operational Mechatronic Systems
The increasing complexity of connected and distributed mechatronic systems developed for safety-critical applications, as e.g. a powertrain of automated vehicles, makes their dependability evaluation a challenging task. Moreover, precise statements about the dependability metrics are of high interest for architectural decisions in the early stages of the design process. System dynamics, possible fault combinations as well as the sequence, duration and impact of various faults and the associated system states must be considered for a realistic evaluation and quantification of the failure behavior. In order to optimize the design of generic mechatronic systems at different abstraction levels and with different component characteristics, this paper examines a method to analytically quantify the stochastic behavior of a system. The proposed approach enables to significantly increase the computational efficiency of the safety analysis of generic fail-operational mechatronic systems without loss in accuracy by automating the dynamic evaluation of convolutional integrals. The application of the proposed safety analysis is demonstrated using an example system with dynamic redundancy.

Talk by Ralph Lange
Bosch has been closely involved with this open source project since the early days of ROS at the startup Willow Garage in Silicon Valley and actively contributes to the development of ROS. In this presentation, Ralph discusses various areas of application of ROS, and gives an overview of Bosch's contributions. He also describes the collaboration in the global ROS community. The talk ends with a short introduction to the ongoing development of micro-ROS, in which Bosch is involved as part of an EU-funded project.

Experimental investigation on acoustics and efficiency of rotor configurations for electric aerial vehicles
Aerial vehicles based on distributed electric propulsion systems have gained great interest. Their rotors, however, create loud and annoying sound, which impends market success. Variations in rotor configuration can be observed on emerging concepts, whereby the main varied parameters are blade size, number of blades and blade distribution.
The focus of this paper is to identify how these parameters can be chosen to optimize eciency and acoustics, including psychoacoustic metrics of single rotors while hovering. Results from experimental investigations done in a hover-test-bench are presented. Rectangular, symmetric blades are used. Experiments are done varying blade size (radius 61 mm to 126 mm), number of blades (2 to 8) and blade distribution (equal and unequal angles). Acoustic measurements are analyzed regarding microphone position, sound pressure level, spectral characteristics and psychoacoustic metrics.
Results show that variations in blade size, number of blades and blade distribution can improve efficiency and acoustics. Influence of these parameters on the acoustic signature at constant thrust is discussed. Conclusions for optimized rotor design at aerial vehicles are derived and supplemented by resulting boundary conditions like assembly space and weight.

Designing Reliable Distributed Systems
Software is disrupting one industry after the other. Currently, the automotive industry is feeling the pinch to innovate in the software business. New, innovative approaches to vehicles and their HW/SW architectures are needed and are currently subsumed under the term SW-defined Vehicle. This trend however does not stop at vehicle boundaries but includes off-board communication with edge and cloud services. Thinking it further, this results in a disruptive technology we call Reliable Distributed Systems (RDS), enabling the operation of vehicles, where parts, such as sensing and compute are no longer bound to the vehicle, but can be performed in an edge-cloud continuum. Reliable Distributed Systems are not limited to automotive use cases. By making compute and sensing ubiquitously available, as well as offering transparent communications, applications in several domains are possible: from industrial automation, over building automation to consumer robotics. However, designing Reliable Distributed Systems raises several questions and poses new challenges for electronic design automation.

Verification of electric axle simulation models via a coupled eAxle-in-the-loop approach
The rapid change from internal combustion engines to electric drives in the automotive industry requires efficient development processes. The early phase of product development is increasingly accompanied by modelling and simulation of the complete vehicle. Extensive tests and optimizations on test benches follow. In this work, both the simulative and the test-based methods are improved by coupling a complete vehicle model with a test bench for electric drivetrains. Such an eDrive-in-the-Loop system enables realistic tests on the drive train test bench through the integration of the complete vehicle and the environment models. The modelling of electric drive trains is also associated with numerous uncertainties due to complex physical relationships. Particularly, thermal effects can only be represented in a very simplified manner in a system simulation. Outsourcing the drive train to the test bench can therefore significantly improve the simulation results.
In contrast to conventional hardware-in-the-loop systems, an object-oriented simulation model is used in this work. This enables a high level of detail and good understanding of the model structure but cannot be carried out on a real-time computer. Therefore, the connection to the test bench is established via a co-simulation with an integrated real-time interface. This requires a middleware that coordinates the data exchange between the simulation and the test bench in real time. With this approach, hardly any changes need to be made in the vehicle model. The co-simulation can be run on a Windows notebook, which means that no additional hardware is required.
With adequate coupling settings in the co-simulation middleware, a stable, accurate and real-time-capable test environment can be assured. The simulation model of the test vehicle can be modified very efficiently, thus allowing a fast analysis of effects on the electric axle due to changes on the (simulated) vehicle system level.
