Research Objectives and Importance
Autonomous driving technology has various advantages, such as reducing traffic accidents, alleviating traffic congestion, and increasing the convenience of transportation. Therefore, research on autonomous driving technology is very important.
Development Process of Autonomous Driving Technology
- Early Research and Attempts: Research on autonomous driving technology began in the mid-20th century, and initially, simple road driving experiments were the main focus. In the 2000s, large IT companies such as Google actively engaged in the development of autonomous driving technology, leading to significant advancements.
- Recent Development Trends: In recent years, autonomous driving technology has rapidly advanced along with the development of artificial intelligence and machine learning. Companies such as Tesla, Waymo, and Uber are making various attempts to commercialize autonomous vehicles.
Core Technologies and Components
Sensor Technology
Autonomous vehicles use a variety of sensors to perceive their surroundings. The main sensor technologies are as follows:
- LiDAR: Uses lasers to create a 3D map of the surrounding environment. It can detect obstacles and measure distances with high accuracy.
- Camera: Collects visual information to recognize road signs, traffic lights, pedestrians, etc. Image processing is performed through deep learning technology.
- Radar: Uses radio waves to measure the speed and distance of objects. It provides stable performance without being affected by weather conditions.
- Ultrasonic Sensor: Used for detecting nearby objects. It is used in parking assist systems, etc.
Artificial Intelligence and Machine Learning Algorithms
AI and machine learning technologies, which act as the brain of the autonomous driving system, analyze complex driving situations and determine the optimal driving route. The main technologies are as follows:
- Computer Vision: Analyzes images collected from cameras to understand road conditions. Object recognition and lane recognition are performed through deep learning.
- Path Planning: Calculates the optimal route from the current location to the destination. It finds a route that avoids obstacles and complies with traffic rules.
- Control System: Controls the vehicle's speed, direction, etc. It monitors the vehicle's status in real-time during driving and sends control signals.
Precise Mapping and Location Tracking Technology
Autonomous vehicles use precise maps to determine their exact location and plan routes. The main technologies are as follows:
- HD Mapping: Creates high-resolution maps that include detailed road information (lanes, traffic lights, signs, etc.).
- GPS: Tracks the vehicle's location using satellite signals. Provides real-time location information.
- INS (Inertial Navigation System): Tracks the vehicle's movement using accelerometers and gyroscopes. Used as a supplement when GPS signals are weak.
