What are autonomous cars?
Autonomous cars, also known as self-driving cars, driverless cars, or robo-cars, are vehicles that can drive themselves without human intervention. They use a combination of sensors, cameras, radar, lidar, GPS, maps, and artificial intelligence to perceive their environment, plan their routes, and control their actions. Autonomous cars can operate in various modes, such as fully autonomous, where the car drives itself without any human input; partially autonomous, where the car assists the human driver with some tasks; or conditional autonomous, where the car drives itself only in certain situations or areas.
What are the levels of automation?
The Society of Automotive Engineers (SAE) has defined six levels of automation for autonomous cars, ranging from level 0 to level 5. Here is a brief overview of each level:
- Level 0: No automation. The human driver performs all the driving tasks.
- Level 1: Driver assistance. The car can assist the human driver with either steering or acceleration/deceleration, but not both. For example, adaptive cruise control or lane keeping assist.
- Level 2: Partial automation. The car can assist the human driver with both steering and acceleration/deceleration, but the human driver must still monitor the driving environment and be ready to take over at any time. For example, Tesla Autopilot or GM Super Cruise.
- Level 3: Conditional automation. The car can drive itself under certain conditions or areas, but the human driver must still be present and ready to intervene when needed. For example, Audi Traffic Jam Pilot or Honda Traffic Jam Assist.
- Level 4: High automation. The car can drive itself under most conditions or areas, but the human driver can still take over if they want to or if the car requests it. For example, Waymo One or Zoox.
- Level 5: Full automation. The car can drive itself under all conditions and areas, without any human intervention or supervision. For example, Google Firefly or Navya Autonom Cab.
What are the technologies involved?
Some of the main technologies in Autonomous cars are:
- Sensors: These are devices that collect data from the environment and send it to the car's computer system. Sensors include cameras, radars, lidars, ultrasonic sensors, GPS, and IMU. They help the car to perceive its surroundings, detect obstacles, and navigate safely.
- Computer vision: This is the field of artificial intelligence that enables machines to understand and interpret visual information. Computer vision algorithms process the images and videos captured by the sensors and extract useful information such as lane markings, traffic signs, pedestrians, and other vehicles.
- Machine learning: This is the branch of artificial intelligence that allows machines to learn from data and improve their performance over time. Machine learning techniques are used to train the car's computer system to recognize patterns, make decisions, and adapt to new situations.
- Connectivity: This is the ability of the car to communicate with other devices, such as smartphones, cloud servers, or other cars. Connectivity enables the car to access online services, such as maps, traffic updates, or entertainment. It also allows the car to share data and coordinate actions with other vehicles on the road.
- Software: This is the set of programs that control the car's functions and behavior. Software includes the operating system, the applications, and the middleware. Software is responsible for integrating all the components of the car, managing the data flow, and executing the commands.
