Simulation has become an essential tool in the development of construction machinery. In addition to the validation of technical features, the assessment of man-machine interaction has become more important within complex working environments. In cases where most attention is paid to the human as the operator, simulations have to fulfil special requirements. Allowing the user to interact with the system implies the need for real time simulation as well as flexible hardware integration and a powerful visualisation. Therefore a modular software framework called SAR-TURIS 3 has been developed meeting all these requirements. In order to support flexible multidomain modelling the Modelica language is being used. This paper presents SARTURIS and its applications, focusing on the integration of Modelica based on OpenModelica using the example of a wheel loader. Since OpenModelica is not yet able to deal with the Modelica Multibody library, a Python-based tool called PyMbs has been developed. It allows comfortable description of multibody systems and export to Modelica code as well as other formats.

“…An important issue to consider when implementing any simulator is validity. According to a technical report (Literature survey on driving simulator validation studies, 2006) of the Pennsylvania Transportation Institute examining the differences in driver behavior in simulated and real environments can be a useful method to validate driving simulators [7][8][9][10][11].…”

Study of a simulator database and an experiment for the evaluation of highway driving safety

Drivers acquire more than 90% of visual information through road signs. However, the road signage along highways can cause driver discomfort and traffic accidents. Conducting experiments along a real highway may cause traffic accidents; therefore, obtaining accurate results from such experiments is difficult. Consequently, this paper reports an experiment for evaluating highway driving safety to reduce the causes of accidents through highway design. It examines the development of a highway database to classify road types in exact accordance with real highways. The study involves an experiment using a driving simulator. The highway database was constructed in two aspects (original and alternative designs) compatible with the DirectX program of Multigen. Four types of physiological measurements (i.e., electrocardiogram, electromyography, electrooculography, and galvanic skin response) were taken from 33 subjects using Biopac equipment in the developed highway database. The skin temperature was measured by a thermal camera. The driver's state was measured through the Subjective Workload Analysis Technique, NASA-Task Load Index, and Modified Cooper-Harper, among various psychological methods. Statistical analysis was conducted to assure the reliability of the results using the Statistical Package for the Social Sciences 12.0 program.

“…One of the in-door test methods for a GPS module is to use an NMEA signal through a RS232 connection (Koo et al, 2008). However, to use this method, we must rework the telematics device to receive the RS232 signal directly.…”

For developing telematics devices, traditional development methods include the unit function test, compatibility test and T-Car, which have some limitations. Telematics devices have various functions that require accounting for the interactions among three major elements of automotive electronics: the vehicle, the device unit and driver. The KAAS (KATECH Advanced Automotive Simulator) system is a virtual-reality-based test environment designed to test and analyze the three elements in one place. One of the difficult functions when constructing such VR (Virtual Reality)-based telematics test environment is to develop a test method for the LBS (Location-Based Service) function such as a car navigation demanding the GPS (Global Positioning System) satellite signals because KAAS is in a fixed laboratory. To overcome these problems, a real-time GPS simulation system, which can be integrated with KAAS, is needed because the location of the vehicle in virtual space is determined purely by the driver's personal intention while driving virtually. This paper presents new concepts needed to construct a VR-based telematics test environment to generate a GPS RF signal, which reflects the continuously changing vehicle location during virtual driving in real-time. To construct this system, the coordinate transform must be conducted from a rectangular coordinate system that is compatible with a virtual 3D DB that is used to construct a 3D image for KAAS using a WGS84 and a longitude-latitude coordinate system compatible with a GPS simulator. Moreover, the real-time HILS (Hardware In Loop Simulation) systems and the CDMA (Code Division Multiple Access) simulation system are developed to evaluate telematics devices. Finally, we show its applications and results.
