In-Vehicle Networking Evolution
o
Current Situtation
• Heterogenous networking
local and prorietary structrures
• Up to 80 different ECUs
o
Market Trends
• More Bandwidth Required
• More Embedded computing power required
• Green Trend, reduce power consumption
Source: BMW, Ludwigsburg 2008
The gateway module is the
central point of convergence
of all networks & dataflow in
the vehicle

o
Tommorow’s in vehicle networking
• Domain Controller interconnected via a
central gateway
• Reduced number of ECUs, increase
functionnality and computing power per
domain controller ECU
• Intelligent satellite modules
