AVL DRIVINGCUBE FORAUDI ADAS/AD VALIDATION
The available Audi adaptive cruise assist (ACA) is a “hands-on”
system that enhances comfort, particularly on long journeys – by
assisting the driver with acceleration and braking plus maintaining
speed and following distance – and keeps the car in its lane at
highway speeds up to 250 km/h and during traffic jam situations.
The AVL DRIVINGCUBE™ will increase the efficiency in validation
an calibration by combining both simulation and the ready-to-drive
vehicle on testbed.
▪ Functional tests can be performed at vehicle level under highly
reproducible conditions.
▪ Different variants and scenarios can be repeated easily
▪ Sensor components are connected to the virtual environment
using over-the-air-stimulation technologies
