More aggressive emission tests such as WLTP and RDE require a dynamic control of the EGR rate, otherwise a too low EGR rate results in increased NOx emissions, a too high EGR rate in particulate emissions. The difficulty in any EGR control is the missing plant knowledge; the EGR rate is controlled although the present EGR rate is not exactly known. EGR flow sensors are available, but due to additional costs they have not found a broad acceptance. A different approach for high pressure EGR investigated in this paper is a control using a second lambda sensor between EGR and inlet valves. This approach improves the dynamic response, but it might come with costs similar to an EGR flow sensor.

New problems and effects require dedicated research and modified methods. The present contribution discusses these new challenges covering aspects like specific vehicle design concepts (e.g. three-wheelers) and the significance of human body mass in relation to the total mass. Some initial simulation results are presented that were gained with an example design of a three-wheeled two seater vehicle. The results show that the seating position and number of passengers have a significant influence on the stability against rollover. Thus they illustrate that the mass of the human body is of importance for the dynamic behaviour of the overall system. The article gives a list of further effects like the stiffness and damping properties of the human body and also the influence of the human as part of the system in terms of control engineering. A strategy is suggested which combines computer simulation and road tests. This strategy minimizes the need for costly testbed experiments for optimizing the simulation models. Particularly when simulation is employed in order to reduce the need for sensors that would require complicated structural modification (e.g. force sensors in suspension components). Ideally, sensor application can be limited to inertial sensors and other positioning sensors like GPS.}, subject = {Leichtfahrzeug}, language = {en} } @book{Borgeest2018, author = {Borgeest, Kai}, title = {EMC and Functional Safety of Automotive Electronics}, publisher = {IET}, address = {Stevenage}, isbn = {978-1-78561-408-8}, pages = {264}, year = {2018}, abstract = {Experience in automotive industry shows that there are in particular two technical reasons why electronic systems in vehicles do not work as expected: software bugs and electromagnetic interference. Malfunctions are more than a mere annoyance, they can damage cars or other goods, injure people or kill people. This book focuses on electromagnetic compatibility (EMC) keeping a close relation to functional safety as required by ISO 26262. It first introduces functional safety and EMC experts to automotive electronics. Since functional safety is still an emerging field, a primer might be useful to automotive engineers and EMC engineers as well. It then introduces to EMC. Signal and power integrity are topics which share the same fundamentals as EMC and are also relevant in some cases. In automotive industry the V-model is still common to describe a development process. For this reason it is necessary to discuss the model and to integrate the safety life cycle and the EMC design flow into the model. After the lecture the reader should be able to recognize and avoid hazards, to avoid expensive EMC problems, to simulate and test for EMC compliance of the car and its components and to fix problems. It helps to learn automotive EMC and functional safety and will stay a reference book after lecture. The book considers all levels from the whole car down to the single electronic control unit (ECU). EMC on integrated circuit level is considered in a few points which are relevant to vehicles.

The proposed control scheme is universally applicable and based on Artificial Intelligence (AI). The lateral control is realized using a Model Predictive Controller (MPC). In order to take into account the diversity of the industrial truck variants, a multi-model approach is used. Therefore, a plant model for each truck variant is integrated into the MPC. In a practical application, the most suitable model has to be selected. This decision is based on AI in the form of an Artificial Neural Network (ANN). It is able to distinguish the different truck variants based on that part of the plant's state vector, which represents the vehicle dynamic characteristics. Thus, the appropriate model can be used, which significantly improves the control quality and guarantees an accurate track guidance of different forklifts. Due to the AI-based selection of the model, the computational effort can be kept low and real-time capability can be ensured.

Human factors significantly influence the driving behavior of a vehicle. Thus, understanding the causal relations between human factors and driving behavior is essential for accurate prediction of vehicle behavior. This is important when autonomous vehicles are expected to behave (cooperatively, according to traffic rules and good praxis) in a human predictable manner, while driving in mixed traffic, involving autonomous, automated, and human driven vehicles.

Within the multitude of factors contributing to these incidents, inattentiveness and the intricate human elements inherent in driving behaviors stand out as pivotal. As indicated by reports and studies on traffic safety, a significant share of accidents can be attributed to driver inattentiveness, encompassing activities such as texting, talking on the phone, or simply being distracted by the surrounding environment. Beyond these observable behaviors lie complex human elements, influenced by factors ranging from cognitive processes to emotional states, which significantly contribute to the occurrence and severity of critical safety events. Inattentiveness is defined as a state in which a driver's eye gaze behavior deviates from attentive driving patterns. It can be influenced by human factors and adverse weather conditions, serving as an indicator of an increased risk of inattentiveness and the potential to contribute to safety-critical events on the road. Recognition of inattentiveness occurs when the average gaze duration on the road or critical areas falls below a specified threshold.

To tackle this issue, we built a Bayesian Network (BN) model for analyzing and predicting congestion probability that can occur due to accidents. In this work, the complexity of handling real data obtained from Darmstadt city is described in detail. The accidents and congestion are correlated by introducing a novel threshold-based approach, which identifies congestion based on the change in vehicle density immediately following an accident. Different thresholds are explored to determine the most reliable measure of congestion, with the T4 threshold emerging as the optimal choice.
