Indy Autonomous Challenge -- Autonomous Race Cars at the Handling Limits

Alexander Wischnewski, Maximilian Geisslinger, Johannes Betz et al.

Motorsport has always been an enabler for technological advancement, and the same applies to the autonomous driving industry. The team TUM Auton-omous Motorsports will participate in the Indy Autonomous Challenge in Octo-ber 2021 to benchmark its self-driving software-stack by racing one out of ten autonomous Dallara AV-21 racecars at the Indianapolis Motor Speedway. The first part of this paper explains the reasons for entering an autonomous vehicle race from an academic perspective: It allows focusing on several edge cases en-countered by autonomous vehicles, such as challenging evasion maneuvers and unstructured scenarios. At the same time, it is inherently safe due to the motor-sport related track safety precautions. It is therefore an ideal testing ground for the development of autonomous driving algorithms capable of mastering the most challenging and rare situations. In addition, we provide insight into our soft-ware development workflow and present our Hardware-in-the-Loop simulation setup. It is capable of running simulations of up to eight autonomous vehicles in real time. The second part of the paper gives a high-level overview of the soft-ware architecture and covers our development priorities in building a high-per-formance autonomous racing software: maximum sensor detection range, relia-ble handling of multi-vehicle situations, as well as reliable motion control under uncertainty.

Real-Time Adaptive Velocity Optimization for Autonomous Electric Cars at the Limits of Handling

Thomas Herrmann, Alexander Wischnewski, Leonhard Hermansdorfer et al.

With the evolution of self-driving cars, autonomous racing series like Roborace and the Indy Autonomous Challenge are rapidly attracting growing attention. Researchers participating in these competitions hope to subsequently transfer their developed functionality to passenger vehicles, in order to improve self-driving technology for reasons of safety, and due to environmental and social benefits. The race track has the advantage of being a safe environment where challenging situations for the algorithms are permanently created. To achieve minimum lap times on the race track, it is important to gather and process information about external influences including, e.g., the position of other cars and the friction potential between the road and the tires. Furthermore, the predicted behavior of the ego-car's propulsion system is crucial for leveraging the available energy as efficiently as possible. In this paper, we therefore present an optimization-based velocity planner, mathematically formulated as a multi-parametric Sequential Quadratic Problem (mpSQP). This planner can handle a spatially and temporally varying friction coefficient, and transfer a race Energy Strategy (ES) to the road. It further handles the velocity-profile-generation task for performance and emergency trajectories in real time on the vehicle's Electronic Control Unit (ECU).

Your Interests According to Google - A Profile-Centered Analysis for Obfuscation of Online Tracking Profiles

Martin Degeling, Thomas Herrmann

Profiling users for the purpose of targeted advertisements or other kinds of personalization is very popular on the internet. But besides the benefits of individually tailored news feeds and shopping recommendation research has shown that many users consider this practice as privacy infringement. Profiling is often conducted without consent and services offer neither information about what the profile looks like nor which effects it might have. In this paper we argue that understanding profiling and thus interacting with the resulting profiles fosters a privacy literacy that is necessary for users to stay autonomous in the information society. We analyze the extent of interest profiling by google and develop a countermeasures that helps to obfuscate these profiles. To do so we analyzed a links lists from a social bookmarking service with regard to the interests they reveal. We found that, although the profiling by google is very unstable we can still use the information to obfuscate the profile.
