Development of the Emergency Brake & Steer Assist represents the next logical step to integrate the Emergency Brake Assist with its lateral assistance complement, the Emergency Steer Assist function. As subject driver examinations show, drivers intuitively combine braking and steering activities dependent on time-to-collision and object overlap in emergency situations. Key factor for the improvement of the overall function is the fused surrounding sensor concept. The ability and robustness of the sensor system plays a major role to display the precise picture of the real surrounding. This is the basis for the assistance system to make the right decision, how to assist the overstrained driver in a crash-imminent situation. The integration of the longitudinal and the lateral assistances opens literally a new dimension. On the one hand this second dimension increases the complexity of the total crash scenario with more challenges for an enhanced sensor system, e.g. the challenge of free space recognition. On the other hand, however, the integral function approach gives the opportunity to address more use cases and with that it will help another time to reduce accident rates and to support the vision zero, traffic without serious injuries and fatalities in future.
