History and Evolution of Autonomy in Self-Driving Cars
The concept of self-driving cars, also referred to as autonomous cars (AC), robotaxis, robotic cars or robo-cars, is not new and has been in development for several decades. These vehicles are designed to perform all driving activities such as perceiving the environment, monitoring vital systems, and controlling the vehicle, which includes navigating from point A to point B without or with minimal human input.
The journey towards autonomous vehicles began as early as the 1950s with trials of semi-autonomous vehicles. The first successful development of a semi-autonomous car was by Japan’s Tsukuba Mechanical Engineering Laboratory in 1977, which required specially marked streets that were interpreted by two cameras on the vehicle and an analog computer.
Subsequent developments in the 1980s saw the launch of Carnegie Mellon University’s Navlab and ALV semi-autonomous projects. These initiatives were funded by the United States’ Defense Advanced Research Projects Agency (DARPA) beginning in 1984. In the same decade, Mercedes-Benz and Bundeswehr University Munich embarked on the EUREKA Prometheus Project.
With increasing connectivity and data-driven approaches, autonomous vehicles are becoming more susceptible to potential cyberattacks, posing threats to individual privacy and public safety. Despite these challenges, brands are continuously implementing AI in self-driving cars to improve user experiences and enhance the role of AI in transportation.
Going forward, as technology continues to evolve, more advanced functionalities are expected to be added to the Advanced Driver-Assistance Systems (ADAS), further enhancing safety on the roads and overall driving experiences.
Levels of Autonomy
The Society of Automotive Engineers (SAE) defines six levels of driving automation ranging from 0 (fully manual) to 5 (fully autonomous). Autonomous driving technology progressively evolves through these levels, gradually reducing the need for human involvement.
Level 0 to Level 2
From Level 0 to Level 2, drivers benefit from systems that control both steering and acceleration/braking simultaneously, although they are required to remain alert and in control.
Level 3 to Level 4
Moving from Level 2 to Level 3, vehicles gain the ability to handle all driving tasks under specific conditions, with the understanding that the driver should be prepared to intervene if necessary. Progressing further to Level 4, the car can manage all functions and address special conditions independently within defined areas, though manual control is still possible.
Level 5
The ultimate goal is to achieve Level 5 autonomy, in which cars won’t even have steering wheels or acceleration/braking pedals. At this level, vehicles will be free from geofencing and will have the ability to go anywhere and do anything that an experienced human driver can do. Currently, fully autonomous cars are undergoing testing in several parts of the world, but none are yet available to the general public.
Key Areas of Technological Advancements
The advancements in autonomous vehicle technology have been substantial over the past years, with numerous companies across the automotive and technology sectors investing immense resources into this area.
