SIM4

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.

VTI, the Swedish National Road and Transport Research Institute, is developing the fourth swedish simulator (named SIM4) which is a moving base driving simulator with interchangeable cabins. It is currently under construction and planned to be operational in the spring of 2011.

Visual system

The visual system consists of 9 projectors providing a 210 degrees forward field of view and 3 LCD displays for the rear view mirrors. Edge blending and geometrical correction is provided by a state of the art system.

Moving base system

The moving base is used to generate forces felt by the driver while driving. It consists of two parts a XY-table providing large stroke linear motion in two direction and a hexapod providing 6-DOF motion capabilities within the stroke of the actuators. SIM 4 is the only VTI simulator to provide large stroke linear motion in both the longitudinal and lateral direction simultaneously. The hexapod is used in the roll and pitch direction to simulate long term accelerations such as driving in a curve or longitudinal acceleration and deceleration. It also provide capabilities to generate road roughness for higher frequencies.

Applications

VTI SIM4 is used both for experiments involving passenger vehicles and heavy vehicles. It is the first hand choice when realistic longitudinal acceleration or a wide field of view is prioritized.
