Abstract

We examined the necessity for plausibilization of test scenarios within usability studies for AV HMIs in driving simulator studies. One group of drivers experienced system-initiated transitions without any obvious reason, the other with plausible reasons (e.g. fog for L3 → L2 transition, broken-down vehicle for L3 TOR). The results showed that reaction times to TORs were not influenced by the plausibility while the type of reaction was. Drivers reported less system trust but still knew how to react to the transitions. Non-plausibility did not negatively affect system acceptance. It can be concluded that plausibilization is not necessarily required for all kinds of research questions.
