o Current Situtation

Heterogenous networkinglocal and prorietary structrures

Up to 80 different ECUs

o Market Trends

More Bandwidth Required

More Embedded computing power required Green Trend, reduce power consumption

o Tommorows in vehicle networking

Domain Controller interconnected via a

central gateway

Reduced number of ECUs, increasefunctionnality and computing power per

domain controller ECU

Intelligent satellite modules

Source: BMW, Ludwigsburg 2008

The gateway module is the

central point of convergenceof all networks & dataflow in

the vehicle

Wireless in and around the car

o Within and around the cabin ISM, Bluetooth, ZigBee, Wi-Fi, NFC/RFID, UWB

o From the garage to home or e-commerce kiosk

Wi-Fi/802.11.P, potentially Bluetooth 3.0, DSRC, UWB

o From the automobile to roadsideinfrastructure Wi-Fi/802.11.P, ZigBee, DSRC

o From the automobile to the rest of the world Cellular, Wi-Fi/802.11.P and WiMAX

Open Connectivity to the external world

Summary

o Electronic is imperative tobalance increasing individual

transportation and reducing

emissions and casualties

o Connection of in-vehicle

network to ITS infrastructure via

the next-gen gateway will enable

the deployement of EV fleets
