AVL DELIVERYING “DRIVINGCUBE” PLATFORM

COMPANY CONFIDENTIAL

ICV2020

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
