Study Notes
Radar Sensors in Automotive Systems
- Radar sensors use radio waves to detect objects, enabling actions or alerts, and can operate in bad weather and dark conditions.
- They provide safety alerts and enable safety maneuvers like Automatic Emergency Braking, Adaptive Cruise Control, Cross-Traffic Alert, and Blind Spot Monitoring.
Types of Sensors
- Radar sensors: detect objects using radio waves
- LIDAR sensors: use laser light for high-resolution 3D modeling and object detection
- Camera sensors: use optical images for object identification
Sensor Ranges
- Short-range sensors (0.5-20m): detect objects in close proximity, often used for rear vehicle corners
- Medium-range sensors (1-60m): used for navigating around town, often used for front/ rear sensors
- Long-range sensors (10-250m): used on highways and in high-traffic areas, often used for forward-facing sensors
Advanced Driver-Assistance Systems (ADAS)
- Rely on advanced technologies like radars, software, and cameras to assist drivers on journeys
- Provide safety alerts and enable safety maneuvers
Benefits of Radar Sensors in ADAS
- Minimize road collisions caused by human errors
- Enhance vehicle safety by alerting the driver of potential problems
- Can take over vehicle control to avoid accidents
- Function well in various light conditions (day/night) and weather conditions (temperature & humidity)
- Easily distinguish between stationary and moving objects
- Can detect multiple items simultaneously
