Self-driving mode (autonomous driving) works by combining several technologies to understand its surroundings, make decisions, and control the vehicle safely.
Main technologies used:
1. Cameras 📷
* Detect lanes, traffic lights, road signs, vehicles, cyclists, and pedestrians.
2. LiDAR (Light Detection and Ranging) 🔦
* Uses laser beams to create a detailed 3D map of the surroundings.
* Measures the distance and shape of nearby objects with high accuracy.
3. Radar 📡
* Measures the distance and speed of other vehicles.
* Works well in rain, fog, and darkness.
4. Ultrasonic Sensors 📶
* Detect nearby objects at short distances.
* Commonly used for parking and low-speed maneuvers.
5. GPS and HD Maps 🗺️
* Determine the vehicle’s location.
* High-definition maps provide detailed information about roads, lanes, and intersections.
6. Artificial Intelligence (AI) 🧠
* Processes data from all sensors.
* Decides when to accelerate, brake, steer, or change lanes.
7. Vehicle Control System ⚙️
* Executes the AI’s decisions by controlling the steering, accelerator, and brakes.
How it works:
1. Sensors continuously collect data about the environment.
2. The onboard computer processes this information in real time.
3. AI identifies objects, predicts their movement, and plans a safe path.
4. The control system steers, accelerates, or brakes as needed.
5. This entire process repeats many times every second.
Most modern self-driving systems rely on a combination of cameras, radar, GPS, and AI. Some companies, such as Tesla, primarily use cameras and AI, while many others combine LiDAR, radar, cameras, and AI for additional redundancy and accuracy.
