For research and development of driver assistance systems a Wizard of Oz vehicle was developed. In this vehicle, a hidden second driver in the load compartment is able to take over parts of the driving task varying the degree of automation from manual control to complete automatic control. Besides alternative control of the driving subtasks a co-operative control of the vehicle is possible by simultaneous manipulation of driver and wizard. This set-up allows the person on the driver's seat to experience not yet existing future driver assistance systems. Hence, sensor development issues are no longer limiting user testing and different degrees of intelligence of the driver assistance system can be realised before spending effort in technical development. Results from user testing can be generated much earlier in the development process and find their entry into the ongoing system design. Besides the advantages for early usability testing, this instrument offers outstanding possibilities in the development of assistance functionality as even very early ideas can be experienced in a real car. Therefore, the Wizard of Oz vehicle is an important instrument within a rapid prototyping approach in the development of assistance systems, completing established development tools such as driving simulators and prototype vehicles. By means of the description of the technical realisation of the experimental vehicle the conception and design of user studies is presented. Two example studies designed for validation of the tool are introduced and described.
