1 1 Prf. Burkhard Geschel Hw Cars Cmmunicate with their Envirnment

2 Telemetry in Frmula , why? 2 analyze chassis data, e.g. handling, aerbalance, tire temperature derive necessary setup changes t imprve car behavir, e.g. wing psitin, brake distributin analyze engine data in terms f perfrmance and life time derive engine/ setup changes, dne by the driver, e.g. lambda, ignitin get bjective data fr race strategy decisins, e.g. pit stps, fuel quantity crrelate the driver feedback with bjective car data, prve driver requests Technlgy is restricted by rules: Only ne way cmmunicatin since 2003

3 Perfrmance f Frmula 1 Telemetry Systems 3 Vice and real time telemetry within ne unit Up t 400 independent data channels GHz transfer frequency Transfer rate up t 1 Mbit/s 2 ms maximal time delay t pit and t head ffice On bard data strage fr lw signal quality regins 600 grams

5 Changes in the industry require business transfrmatin 5 Increasing regulatins (Emissins, Safety..) will drive vehicle and services cmplexity 90% f future vehicle innvatins will be in electrnics and sftware Warranty csts are explding because f increasing electrnics and sftware failures OEM/Supplier cllabratin transfrms frm hierarchical t value net mdel with new entrants frm IT and SW Industry Onging custmer relatinship frm initial vehicle purchase thrugh dispsal Innvative infrmatin-based services and business mdels enabled by telematics will pen up new prfit streams
