- Highlights: Driving simulator study investigating the acceptance of automated reactions in a lane change situation. Manipulating the way the automated vehicle reacts, as well as different situational factors. Compare the acceptance with and without a secondary task. Participants tend to accept the automated vehicle's behavior in the majority of the situation. Abstract: Automated cooperatively interacting vehicles will change the future of traffic completely. Such vehicles will be capable of planning and carrying out maneuvers based on vehicle-to-vehicle and vehicle-to-infrastructure communication, enabling a safer driving experience. However, this gain of safety will only be effective if drivers use and accept the decisions made by advanced automated technology. Especially when drivers are cognitively distracted, new strategies might be necessary, e.g., by further explaining the reason for a cooperative decision. In a driving simulator study, we investigated the acceptance of lane change maneuvers in cooperative situations carried out by an automated vehicle on a two-lane German highway. When the automated system detected a potential lane change ahead, it carried out one of three possible maneuvers: accelerate, decelerate, or maintain speed. Participants ( N = 20) were asked whether they accepted the system's behavior either while being cognitively distracted or in an attentive state. Thus, we investigated the influence of a cognitively demanding secondary task and, inHighlights: Driving simulator study investigating the acceptance of automated reactions in a lane change situation.

Participants ( N = 20) were asked whether they accepted the system's behavior either while being cognitively distracted or in an attentive state. Thus, we investigated the influence of a cognitively demanding secondary task and, in addition, further situational characteristics (Scope of action, Criticality for the lane-changing vehicle, Display of intention) on the acceptance towards the system's behavior. Moreover, participants had to rate the perceived situation's criticality. Results underlined the importance of explicit indication of the intention to change lanes. Furthermore, increased cognitive load led to a higher acceptance of the defensive system behavior. This study contributes to the development of a user-centered interface and interaction strategy for cooperative interacting vehicles. … (more)
