ADAS Sensor Data Flow
How an advanced driver assistance system turns camera, radar and ultrasonic data into warnings and braking or steering actions.
Drawing diagram…
What this diagram shows
- Camera, radar and ultrasonic data are fused into one picture
- Perception detects lanes, vehicles and pedestrians
- Decisions go to brakes and steering over the CAN bus
Prompt used
Data flow for ADAS: a front camera, front radar and ultrasonic sensors feed a sensor fusion module in the ADAS ECU, which builds an object list. Perception detects lanes, vehicles, pedestrians and traffic signs; the planning module decides on lane keeping, adaptive cruise control or automatic emergency braking, sends commands to the brake and steering ECUs over CAN, and shows warnings on the instrument cluster. Selected events are logged for fleet learning.
