Summary

The present driving simulator study investigated the effects of a stationary steering wheel in automatic driving in two parts. In the first part, a stationary steering wheel is compared to a rotating steering wheel on a highway as well as a winding country road. In the second part, the transfer of the driving task to the driver with a stationary steering wheel was examined in detail. The results for the first part show, that on the one hand, a stationary steering wheel increased driver's perceived comfort. On the other hand, a rotating steering wheel enhanced perceived safety, so that overall, no clear preference for either of the two steering wheel modes was observed. In a take-over situation (part two), four options in which the driver performs synchronization from the straight ahead position of the steering wheel himself were compared with options, in which synchronization was performed automatically by the steering system.
