Driver Interventions in Critical Situations During Automated Driving

Highly automated vehicles control the lateral and longitudinal movement of the vehicle in defined use cases, without being monitored by the human driver. The amendment of the Vienna Convention on Road Traffic [1] allows such self-driving vehicles, but requires that the driver is able to switch off or to overwrite the automated system at any time. However, interventions by the driver can lead to critical situations, especially in highly dynamic driving situations. Therefore, this paper investigates at which point driver interventions during highly automated driving can be critical and how the driver can be assisted in order to avoid dangerous driver inputs. To answer these questions, this paper presents test group studies conducted in a driving simulator and a concept for an intervention assistance system.
