We present autonomous driving with high-tech model cars (Audi Q2 on a scale of 1:8). The Audi Autonomous Driving Cup is an international competition aiming at developing fully automatic driving functions and corresponding software architecture, for which our Team AFILSOP won the 1st prize in 2017. Decided for our win is the application of a model-based optimal control algorithm. Since our algorithm considers the passenger's desire, road situation and car dynamics, the computed driving strategy is more reliable and comfortable in comparison to conventional methods. The concept is industrial-oriented and can easily be transferrred to real cars.
