“Pedestrian in the Loop”: An Approach Using Augmented Reality

2018-04-03

A large number of testing procedures have been developed to ensure vehicle safety in common and extreme driving situations. However, these conventional testing procedures are insufficient for testing autonomous vehicles. They have to handle unexpected scenarios with the same or less risk a human driver would take. Currently, safety related systems are not adequately tested, e.g. in collision avoidance scenarios with pedestrians. Examples are the change of pedestrian behaviour caused by interaction, environmental influences and personal aspects, which cannot be tested in real environments. It is proposed to use augmented reality techniques. This method can be seen as a new (Augmented) Pedestrian in the Loop testing procedure.

Technology from Highly Automated Driving to Improve Active Pedestrian Protection Systems

Highly Automated Driving (HAD) opens up new middle-term perspectives in mobility and is currently one of the main goals in the development of future vehicles. The focus is the implementation of automated driving functions for structured environments, such as on the motorway. To achieve this goal, vehicles are equipped with additional technology. This technology should not only be used for a limited number of use cases. It should also be used to improve Active Safety Systems during normal non-automated driving. In the first approach we investigate the usage of machine learning for an autonomous emergency braking system (AEB) for the active pedestrian protection safety. The idea is to use knowledge of accidents directly for the function design. Future vehicles could be able to record detailed information about an accident. If enough data from critical situations recorded by vehicles is available, it is conceivable to use it to learn the function design.

Challenges for Reuse in a Safety-Critical Context: A State-of-Practice Study

The need for cost efficient development and shorter time to market requires reuse of safety-critical embedded systems. One main challenge for reuse approaches in a safety-critical context is to provide evidence that assumptions of the safety artifacts for the reused component are still valid in the new system definition. This paper summarizes the major findings from an explorative study conducted in order to identify the state of practice of reuse in the context of different functional safety standards. The explorative study consists of a set of questions, which have been discussed with interviewees from companies of various domains. The companies act in safety-critical domains with diverse product portfolios. We covered several points of view by interviewing persons with different background. The results of the study reveal industrial challenges, which built the input for the derivation of possible future work based on the identified practical needs.

Stability Analysis of a Two-Voltage Vehicle Electrical System Based on Co-Simulation

In the automotive industry a strong trend towards electrification is determined. It offers the possibility of a more flexible actuation of the vehicle systems and can therefore reduce the fuel consumption and CO₂ emissions for modern vehicles. This is not only valid for typical drive train components, e.g., for hybrid or pure electric vehicles, but also for chassis components and auxiliaries like power-steering pump or air-conditioning compressor. However, a further electrification is limited by the 14V power net of conventional passenger cars. The high electric currents required by new/additional electrical components may lead to increased line losses and instability in the vehicle electrical system. With the introduction of a medium voltage level (≺60V) these problems can be circumvented.
