Connected and Automated Driving Urban Test Site Tampere

Test vehicles

The key assets in VTT's  automated vehicle research are  two passenger cars, a Citroen C4 and a Volkswagen Touareg, which are converted for automated driving,  and which are equipped with the latest sensors, driving monitoring, sensor fusion and co-operative (V2X) technology.  VTT also has developed the MD15 all-terrain vehicle for testing the behaviour of autonomous vehicle systems and machine intelligence algorithms. VTT also has a mobile road side unit, which allows to test road side sensors and V2X technology in a flexible way.

​Citroen C4 - Marilyn 2.0

Marilyn 2.0 is the first passenger car in Finland, which received permission for autonomous driving in real traffic. The car is equipped with advanced sensor technology, software solutions and automated driving functions.  The vehicle has been modified for automated driving, by installing electric actuators for control of throttle, steering wheel, gear handle and brake.

The following sensors have been installed at the front of the vehicle:

  • SICK HD Lidars (110°/6.4°, range: 120 m)
  • Bosch LLR2 77 GHz long range radar (16°/4°, range: 200 m)
  • FLIR AX8 thermal camera 80x60 7.5-13 μm (48°/37°, range ~30 m)
  • IDS HDR stereo camera system
  • Continental SRR 20X Short range radar (150°/12°, 50 m)
  • DGNSS (GPS, Glonass) for positioning
  • OBD-2 connection for reading data from the CAN-bus
  • XSENS AHRS unit
  • ITS G5 and cellular LTE communication devices

At the rear of the vehicle, the following sensors are installed:

  • ibeo LUX Laserscanner
  • Continental SRR 20X Short range radar

The second research vehicle of VTT is a VW Touareg.  The vehicle contains a similar sensor set and the same software as Marilyn 2.0. The following sensors have been installed at the front of the vehicle:

  •  3 SICK laser scanners, from which 1 HD LiDAR (110°/6.4°, range: 120 m)
  • Continental SRR 20X Short range radars (150°/12°, 50 m)
  • Vislab 3DV-E stereo camera
  • DGNSS (GPS, Glonass) for positioning
  • Vehicle CAN-bus connection for reading data from the vehicle.
  • ITS-G5 and cellular LTE communication devices.


MD15 is an off-road track vehicle. It is equipped with a 20 kW diesel engine and hydrostatic transmission. It weighs 1200 kg and has a top speed of 12 km/h and can produce a traction force of up to 8 kNWP_20161028_11_47_00_Pro.jpg
