AV Perception
Surrounding-sensing
Usage of sensors:
perceive road markings, road slope, traffic signs, weather conditions, state of obstacles and state of driver
-
-
Ultrasonic sensor
-
pros: cheap, works normally in low visibility and low lighting conditions
-
Image processing sensor
-
pros: low cost, off-the-shelf components and implementation is almost entirely software
cons: implemented as passive sensors so needs to cope with full range of ambient and uncontrolled conditions. require lot of processing power from controller which generates heat
Challenges
-
-
-
utilization of connected vehicle technology to improve accuracy, certainty and reliability of perception
-
Localisation
-
Global Positioning System (GPS), Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS), Galileo and BeiDou Navigation Satellite System (BDS)
Process
Self-Sensing
-
Vehicle dynamic state
By yaw rate, lateral and longitudinal acceleration
driver inputs
throttle and brake pedal positions, turn signals and headlights
