    Fahrerintentionserkennung zur lichtbasierten Kommunikation mit Fußgängern (2022)
    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: Especially pedestrians rely on the interaction with other road users. The introduction of automated driving systems withdraws this communication from drivers and thus, vehicles need to interact with pedestrians. Therefore, multiple vehicle-pedestrian-communication concepts are evaluated. A driver intention prediction allows pedestrians to learn these newly introduced signals, while driver and vehicle communicate simultaneously.

    Chip-scale optical frequency comb sources for terabit communications (2022)
    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: To keep up with the ever-increasing data transmission speed needs, data center interconnects are scaling up to provide multi-Tbit/s connectivity. These links require a high number of WDM channels, while the associated transceivers should be compact and energy efficient. Scaling the number of channels, however, is still limited by the lack of adequate optical sources. In this book, we investigate novel chip-scale frequency comb generators as multi-wavelength light sources for Tbit/s WDM links.

    Probabilistic Models and Inference for Multi-View People Detection in Overlapping Depth Images (2022)
    KIT Scientific Publishing | KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: In this work, the task of wide-area indoor people detection in a network of depth sensors is examined. In particular, we investigate how the redundant and complementary multi-view information, including the temporal context, can be jointly leveraged to improve the detection performance. We recast the problem of multi-view people detection in overlapping depth images as an inverse problem and present a generative probabilistic framework to jointly exploit the temporal multi-view image evidence.

    Details
    Publication Date: 2024-04-11
    Description: In recent years, OFDM has become more and more important for radar applications. A disadvantage, however, is the need for high sampling rates, which is exactly the starting point of the frequency comb OFDM radar scheme. With its help, the bandwidth in the radar channel can be enhanced without increasing the sampling rates at the same time. In this way, a high range resolution can be achieved without using fast converters with high sampling rates.

    Description: In this work describes the development of a light-based driver assistance system through projections on the road. Under realistic conditions it is shown that information can be transmitted to the driver at night by using projections in front of the vehicle: test persons drive more safely through narrow spaces and react earlier to obstacles. A prototype suitable for road use demonstrates the possibility of a near-series implementation of such a headlamp projection system.

    Publication Date: 2024-04-11
    Description: In this work, two methods are developed and evaluated to integrate and test functional chains of automotive lighting functions on simulation-based test systems. The focus is initially on an approach for the efficient use of light for the display of high contrasts in virtual night driving with a real driver assistance camera. Furthermore, a test method is developed to evaluate pixel-based lighting functions on a hardware-in-the-loop test system based on metrics. In this work, two methods to stimulate and test automotive front lighting functions on simulation-based test benches are developed and evaluated. The first approach deepens the idea to reach necessary high contrasts for virtual night driving with a real driver assistance camera by an efficient use of reflecting light. Furthermore, a test method is shown to test pixel-based lighting functions based on metrics on a hardware-in-the-loop test bench.

    Description: This work introduces a new specification and verification approach for dynamic systems. The introduced approach is able to provide type II error free results by definition, i.e. there are no hidden faults in the verification result. The approach is based on Kaucher interval arithmetic to enclose the measurement in a bounded error sense. The developed methods are proven mathematically to provide a reliable verification for a wide class of safety critical systems.

    Publication Date: 2024-04-11
    Description: The work deals with aspects of image and video exploitation for monitoring, surveillance and security applications in non-cooperative application situations. The term "non-cooperative" refers to scenarios in which, for example, the recording parameters (backgrounds, lighting conditions, etc.) are not or hardly known. The goal is to detect man-made modifications (artifacts) in natural environments.

    Details
    Publication Date: 2024-04-11
    Description: In classical approaches for the torque control of Permanent Magnet Synchronous Machines the torque references are converted into current references by static lookup tables which consider power losses. This procedure is dynamically suboptimal, interdependent and strongly machine-dependent. This work addresses the question: How can a Model Predictive Controller be designed to simultaneously optimize the objectives torque reference tracking and power loss minimization?

    Details
    Publication Date: 2024-04-11
    Description: In this work, discrete-time and continuous-time methods that integrate flexible reference trajectory representations into Adaptive Dynamic Programming approaches are presented and analyzed for the first time. Moreover, theoretical conditions on the system state are derived that ensure the persistent excitation property, which is crucial for the convergence of the adaptation. Real-world applications of the presented adaptive optimal trajectory tracking control methods reveal their potential.

    Publication Date: 2024-04-11
    Description: Currently, dynamically reconfigurable systems are not used in automotive and there is no process model for their development. The focus of this dissertation is to explore methods and approaches for the development of such systems. One major architectural driver is autonomous driving, another is functional high integration on central computing platforms. Taking these into account, dynamic reconfiguration is classified and explored.

    Description: Model-based methods are increasingly being used for a safe and efficient operation of battery cells. For modeling battery cells, fractional models which are characterized by non-integer derivative orders have become established due to their electrochemical interpretability. In this work, methods for parameter and derivative order identification of fractional systems are derived without restriction with respect to the excitation at the begin of identification.

    Description: The electrification and automation of passenger vehicles promote innovations of the entire vehicle architecture. If wheel-selective steered and driven vehicles are considered, challenges of urban regions can be met. In order to combine these development priorities with the alternative vehicle concept, an optimal suspension is designed for the vehicle concept. The topology optimization of a virtual wheel suspension takes place in interaction with a continuous, optimal dynamics vehicle control.
