Gateway 24V Sensor Fusion 24V for commercial, construction and agriculture vehicles (CAV)
Evolution of E/E architectures
Distributed E/E Domain E/E Centralized Megatrends in CAV like CO2
emissions, ADAS and
Connectivity require cost
efficient and high performant
computational power
› Each function has its › Use of Domain
own CPU controllers Such requirements demand high
› Domain independent
vehicle centralized complexity E/E architectures with
› Isolated functions › Performance and
Connectivity oriented approach with central respect to in-vehicle
vehicle brain and communication networks, power
› Ability to handle neural network
complex functions, networks, connectivity, safety
dependability and security
Today Tomorrow Future
Cost efficiency, computation performance, function
complexity

Central gateway using AURIX™
Example: Tractor / Trailer Gateway
Multiple functional domains in
the tractor
Multiple functional domains in
the trailer
A gateway works as data hub
that interconnects functional
domains present across
different networks. Safety and
security here is a MUST!
Data exchange between
gateways also possible
Important: Most of the
systems in CAV applications
Voltage requirements for Commercial, Construction & Agriculture operate in 24 V
