John Deere AUTOSAR adoption approach

Phase out JD/OS and FOCUS. Move all new development to AUTOSAR

Compatibility class 3 32-bit micro common hardware Common BSW and tool set across all product

divisions Leverage suppliers for BSW, CDDs JD develops all applications (features) Drive a top-down design methodology compatible

with model based development and AUTOSAR

Differences from passenger cars

Open communication protocols – SAE J1939 & ISO 11783 (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

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.
