16 AUTOSAR adoption challenges Different Tier 1 relationships License models Legacy subsystems, mixed systems Business case on a per product level ISOBUS compatibility 16 AUTOSAR at John Deere 27 Nov 2014

17 Common needs with passenger cars Functional safety autonomous driving Security (hackers) V2V /V2X M2M / worksite High speed networks 17 AUTOSAR at John Deere 27 Nov 2014

18 Common needs with passenger cars Functional safety autonomous driving Security (hackers) V2V /V2X M2M / worksite High speed networks 18 AUTOSAR at John Deere 27 Nov 2014

19 Differences from passenger cars Open communication protocols SAE J1939 & ISO (ISOBUS) Need for common diagnostic protocols for mixed systems ISOBUS and Agricultural Electronics Foundation Automotive is selling creature comforts and safety features Ag and Construction are selling productivity and economy features 19 AUTOSAR at John Deere 27 Nov 2014

20 Conclusions AUTOSAR is an enabler in agricultural electronics for methodology changes systems engineering managing costs of infrastructure Adoption strategy must be tuned to the business cannot wait for complete cost justification. fully commit to AUTOSAR discover opportunities and optimize them Adopt standard solutions to common problems. Extend the cooperation within agricultural equipment companies. 20 AUTOSAR at John Deere 27 Nov 2014
