5. What is ADAS?
ADAS
Purpose
Functions
➢ Advanced Driver – Assistant Systems
➢ To improve safety -with adas functions

6. ADAS functions
ABS Anti-lock Braking System
-To prevent slipping in the rain/on curved road
-To prevent derailment when braking suddenly
ACC / ASCC Adative Cruise Control
-To calculate the distance and the speed of the front car to
maintain the proper distance with the front car.
AEB Automoatic Emergency Brake -To warn drivers in case of emergency and brake
BSW/BSD Blind spot Warning -To detect blind spots
LDW Lane Departure Warning
-To alert when driver leaves the lane and help to
return to the original lane
LKAS Lane Keeping Assist System
-To directly operate steering wheel when the car
leaves the lane
Automatic
parking..etc
ADAS function Function role

7. Sensors
Sensor
Camera
Radar
LIDAR
- use visible light
- computer vision ex) object detection, lane detection
- use radio waves
- calculate the distance, speed, angle of front car
- pulse modulation, frequency modulation
- use laser
- expensive

8. Sensors used for each function
LSS
(Lateral Safety System)
Camera
Radar
SRR
ARS
- main role : lane detection
- maximum 100m
- guard rail / tunnel recognition
- maximum 100m
- especially oncoming obstacles
- maximum 250 ~ 300m

9. Relationship between automotive sensors and ADAS functions
Sensors used for each function

10. NCAP
N C A P
New Car Assessment Programme

11. EURONCAP

12. EURONCAP – for engineers

13. EURONCAP – for engineers

14. EURONCAP – for engineers

15. Lane Detection
LD
(lane detection)
Function
Steering controller
HMI
(Human – Machine interface)
LKA
LDW
etc
ego lane
adjacent lane
road edge

16. Lane Detection
Grappa
LD
CNN output
1. semseg
2. key point
3. pattern(dash, continuous..)
4. color (blue, yellow, white..)
5. group( I,II,III…)
6. event(bott dot, zigzag…)
Edge detection
-under the horizontal line
-use sobel filter
