During the last years a rapid increase of traffic volume in association with limited road space could be observed. This led to a raising load of the driver while achieving his driving tasks. Therefore so called Advanced Driver Assistance Systems (ADAS) are under development in recent years with an upward tendency. Such systems will relieve the driver and improve safety on the road in the future. A rising number of computed-aided-simulation becomes important for the development and evaluation of such systems. Developing ADAS makes a specific demand on the simulation environment. ADAS interact strongly with their traffic environment. Therefore the simulation has to cover both, a detailed model of the ego vehicle and an adequate representation of the traffic environment. The traffic flow simulation program PELOPS meets these requirements. The newly implemented extension of PELOPS with techniques of Software- and Hardware-in-the-Loop-simulation (SiL- and HiL-simulation) allows system developers a fast functional check and an assessment of new ADAS. External software can be linked to PELOPS via Ethernet-based network communication, which has already been realised for the widely used development tool MATLAB/Simulink. Besides the Ethernet interface PELOPS-HiL (PHIL) gives the developer two other possibilities for providing a HIL-environment: a serial interface which can be used for a connection to a dSpace development platform and a CAN data bus interface. The following article describes by means of chosen examples how flexible the PHIL-simulation can be adapted to a development task and which results can be obtained. [less ▲]

Within the German Research Initiative INVENT, the partial project „Verkehrliche Wirkung, Recht und Akzeptanz (VRA)“ deals with traffic effects, legal aspects, acceptance and economics of driver assistance systems. This presentation gives examples for the consulting services of VRA as well as for the early simulations of a driver assistance system. Such simulations vary in scale from basic functions over driving situations and traffic situations to traffic scenarios. Results are presented for the basic functions and driving situations for a stop-and-go extension of adaptive cruise control. [less ▲]

Within the German Research Initiative INVENT, the partial project „Verkehrliche Wirkung, Recht und Akzeptanz (VRA)“ deals with traffic effects, legal aspects, acceptance and economics of driver assistance systems. The major focus is to accompany the development of such systems rather than evaluating the systems at a later stage. This ensures that wrong development paths are avoided from the beginning. This presentation gives examples for the consulting services of VRA as well as for the early simulations of a driver assistance system. Such simulations vary in scale from basic functions to driving situations, then to traffic situations and finally to traffic scenarios. Results are presented for the basic functions and driving situations for a stop-and-go extension of adaptive cruise control. [less ▲]

In this article methods are shown to use software in the loop (SIL) and hardware in the loop (HIL) techniques in connection with the microscopic traffic flow simulation program PELOPS. With some application examples the use of these methods are depicted. In this context the ossibilities of such coupled simulation tools in development of driver assistance systems are presented. An outlook is given to future enhancements of the described HIL techniques to control for example test benches or assess real vehicles in virtual traffic. [less ▲]
