A driver assistance system is described which provides an automatic road-departure warning and intervention function. The system is intended for drivers who are drifting off the roadway at a shallow angle of departure, recognised by a camera and a vision system, due to inattention, drowsiness, intoxication, or other causes. An integrated set of model-based estimation algorithms serves to anticipate imminent road departures. Interventions are achieved using differential braking - the application of unequal brake torques at the right and left wheels. The driver remains in the loop, always able to provide the primary steering commands. A driver state assessment module is being developed to further adapt to individual drivers and to identify changes in driver behaviour. The algorithms, present simulation results, and preliminary experimental data from a prototype vehicle are described.
