Supply chain Chip Assembled board Controller Function unit Car assembly Final Test Execution SemiCI Placer 1st Tier OEM Responsability Component Electrical Single Multi system functionality functionality system functionality functionality CtoC, CtoX interaction 8
Adaptive suspension system (exemple) Subsystem JIS modul Final assembly + test @mobis, @audi @magna 9
Requirements 1. Cost reduction (assembled board controller) 1. More signal processing directly on the sensor 2. Integration of power electronic components 3. Reduction of components, cables 2. Assistance for technological partners 3. New sensors 4. Safety and security in software 5. Information exchange security 10
Assistance for technological partners Examples for new features Inductive switching surfaces in wood decors Integration of Sensors in Automotive Textiles @ITP, Danzer 11
Safety and security Software integrity requires absence of programming an execution errors Execution Errors Programming Errors Occurrence Hardware execution errors Transient (soft) Correct Program Permanent (from a point in time) Systematic, e. g. design errors time time Temperature Radiation Aging Moisture ESD Mechanical stress Interference time 12
Execution errors which propagate into the execution of the software must be detected Cases: No propagation: No effect on software execution Hardware execution error Software execution error Intrusion by hacker Transient error in software execution Permanent and systematic errors in software execution Interference error in software execution Malicious software execution SIListra Systems error model Error detection 13
