TYPES OF SENSORS
Driving sensors are the unsung heroes behind modern vehicle intelligence, especially in advanced driver-assistance
systems (ADAS) and autonomous driving. Here's a breakdown of the key types:
1. Perception Sensors
These help the vehicle "see" its surroundings:
- Cameras: Used for lane detection, traffic sign recognition, and pedestrian detection.
- LiDAR (Light Detection and Ranging): Creates 3D maps of the environment using laser pulses.
- Radar (Radio Detection and Ranging): Excellent for detecting objects at long range and in poor weather.
- Ultrasonic Sensors: Common in parking assist systems for short-range object detection.
- Infrared/Thermal Cameras: Detect heat signatures, useful for night driving and spotting animals or pedestrians.
2. Localization Sensors
These help the vehicle know where it is:
- GPS: Provides global positioning data.
- Inertial Measurement Units (IMUs): Track acceleration and rotation to estimate position when GPS is unavailable.
4. Proprioceptive Sensors
These monitor the vehicle’s internal state:
- Wheel Speed Sensors: Crucial for ABS and traction control.
- Yaw Rate Sensors: Measure the car’s rotation to help with stability control
-
- Steering Angle Sensors: Determine the direction the driver intends to go.
Each of these sensors plays a role in making driving safer, smoother, and more automated. Want to zoom in on how LiDAR compares to radar,
or how these sensors work together in self-driving cars? I’ve got plenty more where that came from.
