Autonomous Control in Production Logistics. For production systems, different autonomous control methods have been developed. All of these methods aim at enabling parts in a production system to decide about possible alternative routes through a production system.
An autonomous car (also known as a driverless car, auto, self-driving car, robotic car) is a vehicle that is capable of sensing its environment and navigating without human input. Many such vehicles are being developed, but as of February 2017 automated cars permitted on public roads are not yet fully autonomous. They all require a human driver at the wheel who is ready at a moment's notice to take control of the vehicle.
