Perceive the difference: Vehicle pitch motions as feedback for the driver

The feedback of state transitions and intentions of the automation system is very important for obtaining and/or increasing the driver's awareness of the automation system's state during partially automated driving. In this paper, the feedback is realized via rotational vehicle motions and not, as usual, visually. The detailed design of active pitch motions for feeding back state transitions and intentions of the automation system is evaluated in a driving study on a test track. In doing so, the lateral and longitudinal vehicle guidance is carried out by the automation system.
