What are Self-driving Car Sensors?

Self-driving car sensors are electronic components designed to collect data about a vehicle’s environment, including objects, road conditions, traffic, and pedestrians. These sensors work together through sensor fusion to provide a complete, real-time picture that enables autonomous decision-making.

Key sensor types include:

• LiDAR (Light Detection and Ranging) for 3D mapping and obstacle detection
• Radar for detecting objects at long distances and in poor weather
• Cameras for visual recognition of signs, lanes, and pedestrians
• Ultrasonic sensors for short-range object detection and parking assistance
• Inertial measurement units (IMUs) for vehicle stability and navigation

These sensors collectively provide redundancy and accuracy, which are critical for safe autonomous driving.
