Kurzbeschreibung (Abstract)

Automated cars will be able to control themselves, but there will still be a need for take-over requests in critical situations that the automation system cannot handle on its own. In this paper a development and evaluation of three different take-over requests was performed. For this purpose, a total of 70 subjects took part in three independent studies conducted in a driving simulator mock-up. Within the studiesthree different critical scenarios with either a visual, a vibrotactile or a multimodal (combination of visual, vibrotactile and acoustic)take-over requestwere examined. During the automated ride, the test subjects were asked to engage in two different non-driving related tasks. The results show that all three take-over requests serve their purpose and all subjects switched from automated driving mode back to manual driving by using the steering wheel or pedals to intervene into the driving situation. Based on the results published here, a multimodal take-over request should be preferred, as it has the fastest reaction times in critical and non-critical traffic situations and consistently received good ratings within the questionnaires. A vibrotactile take-over request scored the worst in the questionnaires and participants stated that vibration as single stimulus is not being associated enough with a warning signal.
