On the way to automated driving, the installation rate of surround sensing systems will rapidly increase in the upcoming years. The respective technical progress in the areas of driver assistance and active safety leads to a numerous and valuable information and signals to be used prior to, during and even after an accident. Car makers and suppliers can make use of this new situation and develop integrated safety functions to further reduce the number of injured and even deaths in car accidents. Nevertheless, the base occupant safety remains the core of this integrated safety system in order to ensure at least a state-of-the-art protection even in vehicles including partial, high or full automation.
Current networked safety systems comprehend a point-to-point connection between single components of active and safety systems. The optimal integration requires a much deeper and holistic approach. This paper and presentation describe current and future challenges and a clear strategy for the product management as well as for the development and validation of integrated safety systems. The starting points are: market and field requirements based on accident research data, components and technologies brought into the market through driver assistant and automated driving functions as well as design and validation methods to minimize development cost for the targeted performance.
This paper will also include an overview of current and future integrated safety functions, the required functional and E/E architectures and the respective roadmap. Technical examples for pre-and in-crash functions will be described including a design overview, HW components and results.
