An autonomous vehicle uses a fully automated driving system to allow the vehicle to respond to external conditions that a human driver would manage.

What are the 6 levels of autonomous vehicles?
There are six different levels of automation, and as the levels increase, the degree of independence of the driverless car in controlling operations increases.
SAE AUTOMATION LEVEL
At level 0, the car has no control over its operation and the human driver does all the driving.
At level 1, the vehicle’s ADAS (advanced driver assistance system) has the ability to support the driver with both steering and acceleration and braking.
At level 2, the ADAS can supervise steering and acceleration and braking under certain conditions, although the human driver must continue to pay full attention to the driving environment throughout the trip while also performing the rest of the necessary tasks.
At llevel 3, the ADS (advanced driving system) can perform all parts of the driving task in some conditions, but the human driver must be able to regain control when the ADS requires it. In the remaining conditions, the human driver performs the necessary tasks.
At level 4, the vehicle ADS is able to perform all driving tasks independently under some conditions where human attention is not required.
Finally, level 5 involves full automation, where the vehicle ADS is able to perform all tasks under all conditions, and no driving assistance is required from the human driver. This full automation will be enabled by the application of 5G technology, which will allow vehicles to communicate not only with each other, but also with traffic lights, signs, and even the roads themselves.
One of the aspects of technology used in automated vehicles is ACC, or adaptive cruise control. This system can automatically adjust the speed of the vehicle to ensure that it maintains a safe distance from vehicles in front of it. This feature relies on information obtained through sensors on the vehicle and allows the car to perform tasks such as braking when it senses that it is approaching any vehicle in front. This information is then processed and appropriate instructions are sent to actuators in the vehicle, which control the car’s reactive actions such as steering, acceleration and braking. Highly automated vehicles with fully automatic speed control are able to respond to traffic light signals and other non-vehicular activities.
