Benefits ofTarget Simulation

• Target simulation can partially replace driving in the real worldenvironment

• Dedicated scenarios can be re-played

• Sensors can be re-validated more faster after software modifications

• Simulation can help to meet ASIL-D safety requirements more faster

• Random Scenario mode- helps to find unusual problems

Sensor Fusion

• Each sensor has its own unique limitations

• Cameras

o Great at detecting lateral movement, lanes etc

o Limited range

• Radar

o Great at detecting radial movement

o Can suffer from clutter, noise

By testing multiple sensors together, the simulation comes closer andcloser to reality.
