Autonomous Vehicles
What is an autonomous vehicle?
An autonomous vehicle (AV) is a vehicle that can perform some or all of the driving tasks without human intervention.
How do autonomous vehicles work?
Autonomous vehicles use a combination of sensors, cameras, radars, lidars (light detection and ranging), maps, software, and artificial intelligence to sense and navigate the environment. The sensors collect data about the surrounding objects, such as their position, shape, size, speed, and direction. The cameras capture images and videos of the road, traffic signs, lane markings, pedestrians, and other vehicles.
The radars and lidars emit radio waves and laser pulses to measure the distance and velocity of the objects. The maps provide information about the road network, such as the location, topology, geometry, and attributes of the roads. The software and artificial intelligence process and analyze the data from the sensors, cameras, radars, lidars, and maps to represent the environment and plan the optimal path and actions for the vehicle. The vehicle then executes the actions by controlling the steering, acceleration, braking, and signaling systems.
What are the levels of automation in autonomous vehicles?
The level of automation in autonomous vehicles refers to the extent to which the car can perform the driving tasks without human intervention. The Society of Automotive Engineers (SAE) has defined six levels of automation in autonomous vehicles:
Level 0: No Automation. The human driver performs all the driving tasks.
Level 1: Driver Assistance. The vehicle can assist the human driver with either steering or acceleration/deceleration in specific situations.
Level 2: Partial Automation. The vehicle can assist the human driver with steering and acceleration/deceleration in specific situations.
Level 3: Conditional Automation. The vehicle can perform all the driving tasks under certain conditions, but the human driver must be ready to take over when needed.
Level 4: High Automation. The vehicle can perform all the driving tasks under certain conditions without human intervention.
Level 5: Full Automation. The vehicle can perform all the driving tasks under all conditions without any human involvement.
The level of automation in autonomous vehicles affects their design, functionality, safety, and regulation. For example, level 0 and level 1 vehicles require a human driver always to be present and attentive. Level 2 vehicles require a human driver to be present and ready to take over when needed. Level 3 vehicles require a human driver to be present but not always attentive. Level 4 and level 5 vehicles do not require a human driver to be present or attentive at any time.
