Introduction
![Page 7: Automotive Radar and Radar Based Perception for Driverless](https://reader031.vdocuments.mx/reader031/viewer/2022012412/616c41b20316a12b86166e2d/html5/thumbnails/7.jpg)
Driver less driving: A Trend at Hype peak?
7
If you are in „Wikipedia“
and things like „How Stuff works,“
you have reached public societal awareness
2016 Start-ups, new players
and Car-OEMs
flooded the autonomous driving
arena
… and they all
heavily use Radar
![Page 8: Automotive Radar and Radar Based Perception for Driverless](https://reader031.vdocuments.mx/reader031/viewer/2022012412/616c41b20316a12b86166e2d/html5/thumbnails/8.jpg)
Drvless driving – How we approached it

How do we see the drvless future, … that´s how our future began in 2013

COLLISION PREVENTION ASSIST PLUS
COLLISION PREVENTION ASSIST uses radar to constantly monitor closing speeds
between your Mercedes-Benz and the moving vehicles around it. If the system
determines that a collision is likely, it can help you apply the ideal level of braking.
![Page 14: Automotive Radar and Radar Based Perception for Driverless](https://reader031.vdocuments.mx/reader031/viewer/2022012412/616c41b20316a12b86166e2d/html5/thumbnails/14.jpg)
The new E-Class 2016

Active Brake Assist with cross-traffic function: The
system can detect crossing traffic at junctions and, if thedriver fails to respond, applies the brakes autonomously.
It is possible to completely avoid accidents at speeds up
to 100 km/h or substantially reduce the severity ofaccidents at speeds above this level.
![Page 15: Automotive Radar and Radar Based Perception for Driverless](https://reader031.vdocuments.mx/reader031/viewer/2022012412/616c41b20316a12b86166e2d/html5/thumbnails/15.jpg)

PRE-SAFE® impulse side: The system inflates an air
chamber in the side bolster of the front seat backrestnearest the side of the imminent impact in a fraction
of a second, thus increasing the distance between
occupant and door and, at the same time, reducingthe forces acting on the occupants.

The Automation Dilemma
24
Present automatisation practice Future autmatization expectation
Wish for dissipation, relaxing and opportunity of parallel activities
Expected extremely high safety level to autonomous systems
Accidents cased by limitations of human driver Humans perform more right than wrong if driving
Reduce some accidentscaused by human drivers
Additional task: Automating tasks that humans do right
Know your neighbour Know your neighbourhood
Know the relevant objectKnow what is what
