What is an Autonomous Vehicle?
The term “autonomous vehicle” refers to a car equipped with cutting-edge technology that enables it to sense its surroundings, including traffic, pedestrians, and potential hazards, and adjust its course and speed without the need for human input. This revolutionary advancement in vehicle automation holds the promise of transforming the way we approach transportation in the future.
Definition and Levels of Automation
Autonomous vehicles are classified into different levels of automation, as defined by the Society of Automotive Engineers (SAE). These levels range from 0 (no automation) to 5 (full automation), with each level representing a higher degree of automation and decreased human involvement in the driving process.
- Level 0: No Automation – The driver is responsible for all driving tasks.
- Level 1: Driver Assistance – The vehicle can assist with some driving tasks, such as steering or acceleration/deceleration, but the driver must remain in control.
- Level 2: Partial Automation – The vehicle can perform both steering and acceleration/deceleration tasks, but the driver must remain engaged and ready to take control.
- Level 3: Conditional Automation – The vehicle can perform all driving tasks, but the driver must be ready to intervene when necessary.
- Level 4: High Automation – The vehicle can perform all driving tasks in specific, pre-mapped environments, without the need for human intervention.
- Level 5: Full Automation – The vehicle can perform all driving tasks in any environment, without the need for a human driver.
Only Level 5 autonomous vehicles represent a truly driverless, autonomous system, where the vehicle can operate without any human input or supervision. The lower levels of automation, from 1 to 4, involve varying degrees of driver involvement and technological assistance.
SAE Automation Levels

How Do Self-Driving Cars Work?
Self-driving cars, also known as autonomous vehicles, utilize a diverse array of sensor technologies to perceive their surroundings and make informed decisions. These sensors include radar, cameras, and the cutting-edge lidar technology (light detection and ranging) to create a comprehensive understanding of the vehicle’s environment.
The data gathered by these sensors is then processed by the car’s onboard computers, which employ advanced artificial intelligence (AI) and machine learning algorithms to interpret the information and control the vehicle’s actions, such as braking, steering, and acceleration. This sophisticated software enables self-driving cars to identify a wide range of road features and obstacles, including lane markings, curbs, pedestrians, cyclists, and other vehicles.
Sensor Technologies
- Radar systems emit radio waves and measure their reflections to detect and track objects in the vehicle’s vicinity.
- Cameras provide visual information that can be used for computer vision techniques to identify and classify various elements of the driving environment.
- Lidar technology utilizes lasers to create a detailed 3D map of the surrounding environment, allowing the vehicle to accurately perceive and respond to its surroundings.
Artificial Intelligence and Machine Learning
The combination of these sensor technologies and the advanced AI and machine learning algorithms powering self-driving cars enables them to adapt to new situations and scenarios, continuously improving their performance and safety. However, the effectiveness of these sensors can be diminished by poor weather conditions or obscured lane markings, presenting ongoing challenges for the development of fully autonomous vehicles.
