In particular, the introduction of AI methods to sensors, signal fusion, and traffic recognition allows us to step forward from actual level-2 assistance to level-3 A dvanced D river A ssistance S ystems (ADAS), where driving becomes autonomous and responsibility shifts from the driver to the automobile manufacturers. This, however, requires a high-precision risk assessment of failure, which can only be achieved by extensive data acquisition and statistical analysis of real traffic scenarios (which is impossible to perform by humans). Therefore, critical driving situations have to be identified and classified automatically. This paper develops and compares two different strategies—a traditional rule-based approach derived from deterministic causal considerations, and an AI-based approach trained with idealized cut-in, cut-out, and cut-through maneuvers. Application to a 10-h measurement sequence on a German highway demonstrates that the latter has the higher performance, whereas the former misses some of the safety-relevant events to be identified.}, language = {en} } @misc{BielitzBestle, author = {Bielitz, Timo and Bestle, Dieter}, title = {Artificial recurrent model for parameter identification of dynamic systems}, series = {Proceedings in Applied Mathematics \& Mechanics}, journal = {Proceedings in Applied Mathematics \& Mechanics}, publisher = {Wiley-VCH GmbH}, issn = {1617-7061}, doi = {10.1002/pamm.202400015}, pages = {9}, language = {en} } @misc{BestleBielitz, author = {Bestle, Dieter and Bielitz, Timo}, title = {Real-time models for systems with costly or unknown dynamics}, series = {Special Issue: 94th Annual Meeting of the International Association of Applied Mathematics and Mechanics (GAMM)}, volume = {24}, journal = {Special Issue: 94th Annual Meeting of the International Association of Applied Mathematics and Mechanics (GAMM)}, number = {2}, issn = {1617-7061}, doi = {10.1002/pamm.202400008}, pages = {8}, abstract = {Many applications require real-time simulation where the computer model can be executed at least as fast as the underlying physical system. However, as the complexity of models grows, for example, in case of flexible multibody dynamics accounting for body elasticity, this becomes harder even with high-end computers and parallel computing. Further the modeling itself could be too cumbersome to come up with causal models, especially in industrial applications, or modeling is inhibited by unknown physical effects. In such cases, data-based modeling with AI-strategies may be an alternative to come up with real-time capable simulation models. Based on measured or costly simulated trajectories, state function values of the dynamic system are first identified from divided differences of subsequent states, and then used for training a feedforward neural network. This can then be used as an approximate surrogate for further simulations or as part of a real-time application. Applications to the Duffing equation and a closed-loop mechanism demonstrate high conformity of predicted and directly simulated trajectories reproducing even the bifurcation behavior of the Duffing equation.}, language = {en} } @misc{BielitzBestle, author = {Bielitz, Timo and Bestle, Dieter}, title = {Identification of dynamic systems assisted by an autoregressive recurrent model}, series = {Proceedings in Applied Mathematics \& Mechanics : PAMM}, volume = {23}, journal = {Proceedings in Applied Mathematics \& Mechanics : PAMM}, number = {2}, issn = {1617-7061}, doi = {10.1002/pamm.202300086}, pages = {8}, abstract = {The identification of parameters in dynamic systems usually first requires modeling the system as nonlinear differential equations based on physical principles, which then can be evaluated to search for a set of optimal parameters that enable the mathematical model to reproduce some desired behavior of the real system. To overcome the necessity of complex modeling and to possibly reduce the number of extensive experimental evaluations of the real system or numerical evaluations of the differential equations, strategies from machine learning may be applied. The proposed method uses recurrent architectures such as Long Short-Term Memory (LSTM) networks as core to predict the system development from initial conditions and parameter values. The trainable weights of the model are optimized based on a set of training data containing parameter values and corresponding solution trajectories generated by evaluation of the system to be investigated. The trained model may then be used to identify unknown system parameter values related to a specific solution trajectory by solving an optimization problem for the inputs of the machine learning model.}, language = {en} } @misc{NiehoffBestleKupijai, author = {Niehoff, Malte and Bestle, Dieter and Kupijai, Philipp}, title = {Model-based design optimization taking into account design viability via classification}, series = {Engineering Modelling, Analysis and Simulation : the NAFEMS Journal}, volume = {1}, journal = {Engineering Modelling, Analysis and Simulation : the NAFEMS Journal}, number = {1}, publisher = {NAFEMS Ltd.}, address = {Knutsford}, issn = {3005-9763}, doi = {10.59972/c7b5hzx7}, pages = {1 -- 12}, language = {en} }
