Technology that can safely drive humans or goods to their destination without, or with less, human operation. Automat- ed driving systems for cars, trucks, and buses will eventually be able to sense the environment and make human-like decisions, using an onboard computer, sensors, and communication with a data center or roadway. This article will focus on self-driving cars (Fig. 1). + ward ' s science Content • Key technologies of automated driving - Navigation - Environment perception - Vehicle control - Path planning • Issues and impacts Key Concepts • Automated driving systems — sometimes referred to as autonomous, intelligent, driverless, or self-driving vehicles — are capable of monitoring the road environment using onboard sensors to provide inputs to software that automatically plans the driving route and controls the vehicle as it moves toward a predetermined destination. • The key technologies of automated driving are navigation, environment perception, vehicle control, and path planning. • In addition to technical issues, some legal, regulatory, and ethical issues need to be considered for the commercialization of automated driving systems. • The development of automated driving will most likely be realized in a gradual way and, once realized, is expected to have a profound impact on human society. Fig. 1: The key technologies of a self-driving car. The levels of driving automation as defined by the Society of Automotive Engineers (SAE) International are listed in the table. If the classification is level 3 or higher, then the system is considered an automated driving system.
