    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.

    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: By providing a high resolution at high distances in a broad field of view, LiDAR sensors are a key element in automated driving cars. However, in harsh environmental conditions, particles from rain or dust attach on the outer surface of the sensor and cause a degradation of the overall performance. This work introduces several methods to detect and characterize those particles, realizing the integration of an intelligent and fully automated cleaning system to restore the required performance.

    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: The simulation of ceramic phosphors by means of the diffusion approximation of the radiation transport equation is extended from rotationally symmetrical cases to general, three-dimensional problems. The phosphor is simulated with the diffusion approximation for a temporal and spacial variable laser light source for the first time. Therefore, different laser light sources are being compared to evaluate, which one of the alternatives is best suited for the intended use in an automotive head lamp.

    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?

    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.
