What is Autonomous Driving? Why?
• An Autonomous car : A vehicle which is capable enough to fulfill human-
transportation capabilities without human inputs.
• Why do we need it?
• Accroding to The Eno Center for Transportations,Washington D.C,
- 90% of road accidents are actually human errors
- If 10 % cars are autonomous,
- 2,11,000 fewer crashes , 1100 lives can be saved p.a.
- If 50% cars are autonomous,
- 1.88 million fewer crashes, 9600 lives can be saved p.a.

• Sensors :
- Raw input data
• ECU (Processor) :
- Decision Making
- Cheking functionalities of all
control drives
- Sending signals to actuators
according situation
- Alerts to Driver using UI.
• Actuators :
- Steering control
-Throttle control
-Differential control
- Motion contorl
- Break control

Multi-Sensor Collaboration
Seminar Automotive Sensors
Chair for Measurement and Sensor Technology
Univ.-Prof. Dr.-Ing. O. Kanoun
• A self-driving car, to be deployed in real-world driving environments, must be
capable of reliably detecting and effectively tracking of nearby moving objects.
• Sensor fusion for object detection
developed by Carnegie Mallon
University.
• LIDAR – For edge detection
• RADAR – For point detection
• Vision sensor / Camera – For
vision target
6x LIDAR
6x RADAR
3x Vision sensors / Cameras

• A radar – LIDAR pair at different
heights – Maximize the reliability and
range of measurements.
• 200 m – Any side of the vehicle
• 60 m – Object detected by at least 2
sensors (i.e. radar and LIDAR or radar
and camera)
• Sensor setup, Image : http://www.cmu.edu
• Coverage of sensors and blind spots, Image : http://www.cmu.edu

Data extraction and Observation
Seminar Automotive Sensors
Chair for Measurement and Sensor Technology
Univ.-Prof. Dr.-Ing. O. Kanoun
• High definition
screenshots of scenes.
• 3-D point clouds.
• Line segments or
junction of lines (“L”)
shaped.
• 2-D position and velocity
of objects.
• Precise measurements
even after 200m.
• Data from multiple sensors of same type – considered as 1 module.
• Sequential sensor method applied
a) Detection using camera, b) Detection using LIDAR, c) Detection using radar, Images : ICRA 2014, sensor fusion
