Foresighted Driving

In future, telematics (maps,

communication and networking)

will play an increasingly important

role in safe and efficient driving.

Danger alert

Obstacle alert

Warning in situations with

poor visibility or reduced

road grip

Warning at road works

vehicle communication

Obstacle behind a bend Slippery road surface

Vehicle-to-Vehicle Communication

Requirements

Available everywhere

Existing technology

No operating costs

Solution

Wireless LAN

Available on every computer today

Information distribution via Ad Hoc networks

In rural areas:

Store & forward

On highways:

Ad Hoc networking

Routing protocols coordinated with the project NOW Network on Wheels

Ad Hoc Communication

Random group of vehicles creates an(Ad Hoc) communication network

Some vehicles leave the network, others join it Communication between vehicles in new configuration

Advantage of Ad Hoc: no operating costs


11/14

Danger Identification

The vehicle as sensor

Vehicles already feature a large number of reliable

electronic driving safety systems today (ABS, ESP, )

All systems function more or less independently asstand-alone applications

Goal: information from these systems should be used

in a coordinated fashion to help identify dangers


12/14

Danger Identification

Goal: affordable solution for everybody in particular also small cars Retrofitting possible

a) with appropriate danger detection system adapted to the vehicle

b) without danger detection system, to relay information

Future communication architectures & related challenges

Applications (Traffic-, FleetManagement, etc.) will function

via seamless access to various

communication technologies

(CALM +)

Interfaces, handover procedures,

delay etc.

Local communication (Ad Hoc)

has to be harmonised to

infrastructure communication

Way from WILLWARN scenarioto CVIS scenario


14/14

Future communication architectures & related challenges

Integration of personal mobiledevices (PDAs) has to be

ensured

Evolution from vehicle-to-vehicle

communication

to road user to road user

communication (R2R-Com)

Systems will be very complex

Have to be adequately explained

to the driver

Must be easy to handle so that the

driver can concentrate on his main

task, which is

Driving the vehicle!
