Braking is the most frequent maneuver in emergency situations quite often, however it has been observed that the driver did not brake hard enough. To help the driver an assisting emergency braking system was envisaged. The aim of this study is to define requirements for emergency braking systems based on the behaviour of the driver. One hundred drivers volunteered to drive on a closed track in order to study their braking behaviour. Participants were not informed that they would be placed in an emergency situation. Their behaviour was assessed by measurements on the car and video recordings. Their workload and emotional strain were evaluated by analysis of electrodermal recordings. From these electrophysiological measures it has been possible to distinguish standard accurate and emergency braking. It was found that skin resistance is relevant to workload whereas skin potential is more linked to emotional strain.
