Current partially automated driving systems enable lane following and lane changes on the motorway. Driver input and safety measures vary for these systems, as there are no legal regulations on how the human-machine-interaction should be designed. In this paper, an interaction concept for a partially automated lane change is presented. The initiation of the lane change includes a request by the driver and a feasibility check by the system. Based on the results of expert interviews, various input variations were implemented and evaluated in a driving study on the motorway. The experts generally preferred the activation of the indicator lever in combination with steering wheel contact for lane change requests. This input variation enables the driver to express his wish without active intervention in the vehicle guidance. For activation of a so-called lane change abort, which results in an automated return to the starting lane, the experts preferred steering input to the starting lane.
