In the framework of large scale project interactive co-funded by the European Commission Ford develops an active safety system for the supported and autonomous avoidance of rear end collisions by intervention in braking and steering. This paper describes the system and its architecture (especially sensor architecture) and focus an the threat assessment for the decision making related to the initiation of the interventions. The system interventions have to be initiated as early as possible in order to avoid the collision and avoid unstable vehicle dynamics situations. In parallel the reaction has to be delayed long enough until it is likely that the driver will no longer intervene or respectively he is no longer able to intervene. For this reason an experiment is conducted with 26 subjects. The purpose of the subject is to determine the braking and steering onsets when the driver avoids a rear end collision either by steering or braking. The scenario is chosen in a way that the subjects are aware of the stationary obstacle in their Jane. Additionally they were instructed to initiate the corresponding avoidance maneuver as late as possible and delay the steering and braking until they think that any further delay of their action would result in a collision. The results show that the onsets are much earlier than the physical limits for both steering as well as braking. It can be assumed that the driver would not consider any system intervention beyond these onsets as an override by the system. If he would be aware of the situation he would have intervened himself at an earlier stage. The results of the experiment will be used for the refinement of the threat assessment in a next step.
