Design of an active trailer-steering system for multi-trailer articulated heavy vehicles using real-time simulations
Proceedings of the Institution of Mechanical Engineers Part D: Journal of Automobile Engineering, 2020Co-Authors: Xuejun Ding, Steve Mikaric, Yuping HeAbstract:This paper presents the design for an active trailer-steering system of multi-trailer articulated heavy vehicles using Driver-Software-in-the-loop real-time simulations. A linear yaw-plane multi-trailer articulated heavy-vehicle model is generated to derive an optimal active trailer-steering controller. Then, the controller is reconstructed in LabVIEW and integrated with a vehicle model for a tractor- double-trailer combination developed in TruckSim. The Driver-Software-in-the-loop real-time simulations are conducted on a vehicle simulator. The Driver-Software-in-the-loop real-time simulations indicate that the active trailer-steering controller can effectively improve the low-speed manoeuvrability and high-speed stability of the multi-trailer articulated heavy vehicle when testing using a low-speed 360° roundabout path-following manoeuvre and a high-speed single-lane-change manoeuvre respectively. The investigation based on the Driver-Software-in-the-loop real-time simulations paves the way to future development of electronic control units for the active trailer-steering system using Driver-hardware-in-the-loop real-time simulations.

Real-Time Simulations for Design of Active Safety Systems for Multi-Trailer Articulated Heavy Vehicles
Applied Mechanics and Materials, 2012Co-Authors: Xuejun Ding, Yuping HeAbstract:This paper introduces a design of active trailer steering system (ATS) for multi-trailer articulated vehicles (MTAHVs) using Driver-Software-in-the-loop (DSIL) real-time simulations. A yaw-plane MTAHV model is developed to derive an ATS controller. Then, the real-time versions of the controller and MTAHV models are constructed in LabVIEW and TruckSim, respecitvely. With the integration of these models, the real-time simulations are conducted with a vehicle simulator. The simulations indicate that the controller can effectively improve the MTAHV’s directional performance under the specified test maneuvers.

A Tool for Databus Safety Analysis Using Fault Injection
Lecture Notes in Computer Science, 2020Co-Authors: Dawid Trawczynski, Janusz Sosnowski, Janusz ZalewskiAbstract:In real-time safety-critical systems, it is important to predict the consequences of specific faults in databus logic and Driver Software on the safe operation of a databus. For this purpose we have developed a test-bench based on the TrueTime simulator extended by adding a fault injection capability, with new network models and fault modeling strategy. Faults are simulated by disturbing specified parameters of the databus model. In this paper, we present the modeling approach, the fault injection scenarios, and illustrate it with examples of the impact of the simulated faults on data throughput, message latency and bus scheduling for CAN and TTCAN networks.

ICMLA (2) - Application of Adaptive Artificial Neural Network Method to Model the Excitation Currents of Synchronous Motors
2012 11th International Conference on Machine Learning and Applications, 2012Co-Authors: Ramazan Bayindir, Ilhami Colak, Seref Sagiroglu, Hamdi Tolga KahramanAbstract:In the classic ANN-based approaches, the synchronous motor parameters mostly could be modeled with n-hidden layered networks. It is an important challenge in Driver Software development is to realize complex mathematical models in real time environments and circuits. This paper presents an Adaptive Artificial Neural Network-based (AANN) method to easily model excitation current of synchronous motors. It has a simple network structure and less processing units (nodes) more than classic ANN. The main purpose of this method are to estimate the excitation current and also to assist designers to model excitation current easily and to develop complex Driver Software with low degree programming effort while improving the efficiency of classic ANN-based approach. In the adopted approach, the activation functions of nodes in the hidden layers of multilayered feed forward neural network have been determined by using a heuristic method. The experimental results have shown that the proposed method successfully creates single-hidden layered simple networks have less node number than classic ANN-based solutions and achieves the tasks in high estimation accuracies.
