Design of Control Transfer Rituals for Automated Vehicles

In 1886, humanity started a great effort to move away from horseback and build a carriage over which they have full control. A century-and-a-half later, we have succeeded to the degree that we are looking for a way to relax in our automobiles. The MEDIATOR project tackles the transitional period between conventional automobiles and fully...

Does personality affect responses to auditory take-over requests? Validating a simulator experiment setup through a N=1-study

Automated vehicles with conditional driving automation (SAE level 3 (SAE, 2018)) will request the human driver to intervene when reaching its system boundaries by issuing a take-over request (TOR). This study is investigating whether a speech-based auditory take-over request is influencing the time it takes from automated to manual driving,...

A method to assess safety implications during authority transitions in automated driving

The question of how well in terms of safety can a driver take over control of an automated vehicle in response to an emergency situation is of crucial importance. Most of the studies performed so far focus on the drivers’ reaction times and the mechanisms behind the transition. In this study, an effort is made to incorporate the braking times...

Quantifying Take-Over Quality: A Novel Approach Utilizing a Scenario-Specific Optimized Reference Trajectory

Due to recent advancements in automated driving systems, drivers are able to withdraw themselves from the control loop of the vehicle in certain driving situations. However, system limits occur relatively frequently, which results in the driver having to take back control. It is argued most currently used take-over quality quantification methods...

Evaluating take-over requests with directional audio: Assessing the effect of ipsilateral and contralateral verbal stimuli on response times and visual behavior

Taking over control from an automated vehicle may take a substantial amount of time if the driver is not engaged in the driving task. Take-over requests containing directional information of hazardous surrounding cars could aid the driver in taking over the vehicle faster. However, whether the directional information should be presented...
