High standards regarding quality and performance of the automated vehicle
Measures that product needs to meet
Basic functionality is technologically given
Has been demonstrated in various projects
Together with electric driving, automated driving is tomorrow’s subject matter.
Introduction to the Research Project
Resulting Starting Position – Automated Driving
3
Existing measures for testing and release are insufficient, too cost-intensive and too complex
Consequently, the introduction of highly automated driving features today can only be achieved with great expenditure.

How can complete-ness of relevant test runs be ensured?
What do the criteria and measures for these test runs look like?
What can be tested in labs or in simulation? What must be tested on proving grounds, what must be tested on the road?
Which tools, methods and processes are necessary?
What human capacity does the application require?
What about technical capacity?
Is it sufficiently accepted?
Which criteria and measures can be deducted from it?
Introduction to the Research Project
Major Questions of the Project
