Development of predictive safety functions for the activation of restraint systems


The activation of restraint systems (airbags, seat belts) in accident situations is so far based on sensor signals (acceleration, pressure, impact sound), which have to be evaluated within a short time interval after the moment of collision. In addition to the limited time period, during which safety measures can be initiated, and the large number of necessary sensors this results in a strong dependence of implemented crash functions of the vehicle structure. The increasing performance of predictive vehicle sensors allows the development of new safety systems. These systems can support conventional crash sensors by preparing restraint systems in case of an approaching accident and activating them reliably and precisely timed depending on situational aspects.


The objective of this project is the development of a model-based functional concept, which chooses the best sensor information in terms of the current environmental conditions and uses it for the preparation and activation of restraint systems. The triggering of the restraint systems is supposed to be initiated on the base of an extensive recognition, analysis and predictive interpretation of the environmental situation.


- Requirement definition and development of a concept based on an overview over the state of research and related projects
- Development of a method for the evaluation of object data (velocity, angle, offset, type, size, …) and object tracking under the requirements of accident scenarios
- Prototypic integration of the developed functional modules into the simulation as well as into a concept car and test of the overall functionality
- Implementation and integration of the functional modules into a serial control unit
- Evaluation of the developed functions


Whereas the restraint systems are initially supposed to be activated after the time of collision but more robust and situation-specific than within common systems, it is the long term aim to already initiate the activation before the time of collision only by predictive sensors and car2x communication.
