6 Automotive Systems Engineering in the Development Process Providing internal departments + suppliers with virtual prototypes Internal dept. 1 or supplier 1 Component A Internal dept. 2 or supplier 2 Component B Internal dept. 3 or supplier 3 Component C Internal dept. N or supplier N Component Z Virtual Prototypes Integration workshop Internal development depts. or suppliers Development + test of full system in full vehicles in scenarios Pre-calibration of the system Test driving department Calibration (virtual + real) Release (also virtual) Engineers can test and release their systems in a full vehicle: automotive systems engineering! 7

7 Automotive Systems Engineering in the Development Process Using virtual prototypes throughout the entire development process Same maneuvers + same evaluation criteria Reuse of virtual prototypes and maneuvers saves time and costs 8

8 Test Scenario Definition Test scenario Static objects Traffic signs, buildings, road incl. markings,... Virtual prototype AD functions, (sub-) system models, driver,... Dynamic objects Cars, trucks, pedestrians,... Surrounding of virtual prototype Environmental conditions Lighting, temperature, precipitation,... 9

10 Environment Function / fusion Use Case-Specific Sensor Models Overview The use case drives the level of detail: Ideal Sensors for rapid prototyping / proof of concept HiFi Sensors for function development & testing Raw Signal Interface for component / signal processing development & testing Virtual scenario Ideal Sensor Virtual prototype with system under test HiFi Sensor Raw Signal Interface Processing / tracking Use case-specific sensor models for real-time simulation! 11

11 Do the algorithms work? Requirements: Function interface (e.g. object list) Technology-independent Easy to parameterize Does the function generally work? Requirements: Function interface (e.g. object list) Technology-specific Physical phenomena Processing/Target selection included Does the sensor component work? Requirements: Raw signal interface Technology-specific Detailed physical effects 12

12 Suitable Sensor Models for Every Use Case Ideal Sensors for verification and early development phases Scenario Function / Fusion Ideal Sensor Information extraction Object selection HiFi Sensor Propagation reduced to essentials Target selection RAW Signal Interface Signal propagation Processing / tracking 13

13 Object and Line Sensor Highlights Object sensor detects and tracks surrounding traffic Object list Relevant target Line sensor generates object list of lane boundaries Road markings Traffic barriers Application areas ACC, LDW, LKA, 14

14 Radar Sensor Outputs: Object lists with Relative position / velocity / acc Classification of object / dynamics / confidence Probability of existence / obstacle Received power / RCS / SNR Features: Detection based on SNR including occlusion Antenna gain Object RCS Propagation loss Object fusion based on resolution cell Latency, noise False negatives (False positives) 15
