|Renault Launch HELIOS for Lighting Simulation
Renault has dedicated resources to simulation to develop thermal behaviour, vibration, pedestrian crash, realistic rendering of lit aspect, simulation of a light beam distribution on the road.
This simulator is composed of a spherical screen with a field of view of 225° and a pixel size equivalent to the precision of the human eye (1/60°), beamers and a vehicle which gives to the driver the feeling of real driving.
With these 2 characteristics, it will be possible for Renault to reach the best level of representation of a light beam, especially for high beam which is the function on which all the carmakers are focused now with the development of ADB solutions. Regarding the simulation software, the simulator uses SCANeR™ from AV-Simulation. The driver is installed in the cockpit of a real car. All the commands of this car are monitored, and a computer manages the behavior of a virtual vehicle. Thus, it is possible to drive on a virtual road projected on the spherical screen. In addition to this simulation, it is possible to add on it, light beam patterns. It can be basic functions like low beam and high beam or more sophisticated ones like adaptive Driving Beam with the integration in the simulation of additional vehicles, virtual front camera and a software for the activation of different part of the light beam.
It is also possible with specific glasses and tracking systems to have a 3D representation of the virtual environment for a better immersion in the virtual environment.
A presentation of Renault lighting simulators and lighting department facilities was done for the students of the 4th session of ELS Master.
