    SHAKE - an approach for realistic simulation of rough roads in a moving base driving simulator2010In: Trends in driving simulation design and experiments: proceedings of the driving simulation conference Europe 2010, Arcueil: Institut national de recherche sur les transports et leur securite, INRETS , 2010, p. 135-143Conference paper (Refereed)
    Abstract [en]

    With today’s advanced measurement equipment for measuring roads, it is possible to measure road geometry at high precision within a large span of wavelengths. Detailed information about the roads longitudinal and lateral profile, including macro texture, would in theory be sufficient for a realistic reproduction of road induced vibration and noise in a driving simulator. Especially, it would be possible to create a direct connection between the visual information of the road condition and the ride experience, which would increase the level of realism in the simulation. VTI has during three years performed an internal project called SHAKE with the aim to develop and implement models in VTI driving simulator III that use measured road data for generating realistic vibrations and audible road noise connected to the visual impression presented on the projection screen. This has indeed resulted in an more realistic driving experience, and a validation study with test persons driving both in the simulator and in the field has been undertaken. The OpenDRIVE standard is used as a framework for describing the road properties (e.g. visual, vibrations and noise). For this purpose some augumentations to the OpenDRIVE standard had to be made. This paper describes the technical implementations in the driving simulator, along with results from test drives on the implemented road sections

    Improving the realism in the VTI driving simulators: Shake final report2012Report (Other academic)
    Abstract [en]

    The Swedish Road and Transport Research Institute (VTI) has three advanced moving base driving simulators. The aim of this project was to develop and implement new models concerning vibration, noise and graphics in order to improve the realism in the simulators. Moreover, a validation study was to be conducted.

    Within the frame of the project the following were achieved:

    • improvement of the tyre/road vibration models,
    • •improvement of the motion system by changing the rotation centre,
    • •improvement of the noise module facilitating reproduction of noise from tyre/road,
    • •synchronization of the impressions from graphics, noise and vibrations caused by the road surface.

    The validity of the models was tested in the VTI Simulator III. Statistical testing of differences between the car and the simulator indicated absolute validity for the subjective ratings of evenness and noise level and the objective measure speed, with the exception of areas surrounding speed limit signs where only relative validity was found. Relative validity was also indicated for the variable overall comfort. The results from the different validations show that the improvements have been successful and the driver in the simulator can now see, hear and feel the sensation of any road surface irregularities exactly when the wheels hit that part of the road. However, several improvements in the simulator models can still be desired.

    Förutsättningar för en avancerad körsimulator i Göteborg2008Report (Other academic)
    Abstract [en]

    Driving simulators play an important role in many fields of research and development. In vehicle industry simulators are used as powerful tools for product development, often with focus on HMI, active safety and vehicle dynamics. In a prestudie, financed by Test Site Sweden, VTI has investigated the possibilities to establish and run an advanced, world-class driving simulatorin Gothenburg, characterized by: - a possibility to use and shift between personal car and lorry cabins - at least 180 degree horizontal view - an advance moving base, with solid mechanical properties, allowing linear movements in x- and y-direction, combined with titling for the simulation of static acceleration.
