2 Multiple Advanced Driver Assistance Systems Main Topics 1 Driver HMI Vehicle 2 Synergy Architecture Fusion n Integration HMI Algorithm Component 1 Component 2 System Sensor... ECU Siemens VDO Automotive AG 2005 Happe/Lütz SV C RS DA Questions to be answered for multiple Advanced Driver Assistance Systems () HMI: How many information does the driver need and where do we put it? Architecture: What are the requirements on a network of multiple Advanced Driver Assistance Systems ()? Synergy: How can sensors be used for multiple functions? Fusion: What kind of fusion of different sensors can be made? Siemens VDO Automotive AG 2005 Happe/Lütz SV C RS DA

3 Advanced Driver Assistance Systems SV Comfort / Rela Driving Pleasure & Fun Driving without stress e.g. LDW, ACC Driving with less fuel consumption, less cost e.g. ACC Stop&Go Driver Enjoy driving, but never leave the limit Driving like on the home course e.g. Sensitive Guidance, Night Vision, Object Detection Economic Driving Orientation & Overview Siemens VDO Automotive AG 2005 Happe/Lütz SV C RS DA Advanced Driver Assistance Systems System Approach Siemens VDO Automotive AG 2005 Happe/Lütz SV C RS DA

4 Concept Car System Level System Level 0 multiple System Levels Concept Car System Level 1 complete functionalities including HMI, controlling,... System Level 2 closed sub-functionalities (e.g. Camera & ECU with defined interface) Component Systems which support eclusively functions (e.g. sensors, actuators, displays, lighting,...) Enabler Systems with impact (e.g. brake, steering, display,...)
