Increasing complexity of advanced restraint systems due to the large number of protection devices, additional sensor systems and adaptive actuators require a modular system architecture, transparent data management and a sophisticated system control. Robert Bosch GmbH has developed an appropriate concept. By using fast and reliable bus systems such as vehicle CAN bus or the Bosch Firing System, the availability of any safety related data enables superior restraint management specific to conditions and priorities. The Bosch Smart Restraint System Control is based on innovative sensor systems such as occupant, rollover sensing or precrash sensor. Smart restraints will rely on the Bosch Interior Sensing Module which properly discriminates occupant presence (AOS), occupant out of position (OPP) and child seat presence and orientation (CSD). The Bosch Smooth Inflation Concept (SMINC) for smart airbags is based on an algorithm discriminating between hard crashes, where full inflation is required, and soft crashes, where smooth inflation is more suitable. For belted occupants, reduced inflation (75 % inflator output) is sufficient, whereas staged inflation (with 30 ms time delay between two stages) is required for unbelted occupants. Smooth inflation significantly reduces loadings for occupants out of position. A comprehensive concept for smart restraint control combines the Smooth inflation Concept for airbags with tailoring belt load according to occupant conditions such as weight or seat position.
