By comparison, differentiation is made between five different steps on the way to autonomous driving. In assisted driving at level 1, individual assistance systems either provide support in processes such as accelerating and braking or in steering. In partially autonomous driving at level 2, the support goes a step further: Certain functions, affecting both longitudinal and lateral control, can be passed by the driver to complex assistance systems. This includes a corresponding congestion assistant, which brakes or accelerates up to a certain speed, adjusted to the other vehicles. However, the driver must monitor the process and be able to step in at any time. In highly automated driving (level 3), the driver can temporarily hand over control in predefined situations completely. As soon as the system requests, they must take over the steering wheel again.
The Audi AI:ME concept is designed for what is referred to as level 4 fully autonomous driving. This means that on certain routes the system is fully in control, within its limits. If necessary, it can bring the vehicle to a stop autonomously. If the steering wheel and control elements in the Audi AI:ME are not required, the steering wheel is retracted in a beautifully choreographed movement. It is then almost fully concealed by a stowage compartment featuring a walnut surface, providing optimum space for users to relax in the Audi AI:ME’s cabin.
Then comes the last step: level 5 – autonomous driving. At this stage, the vehicle operates completely without a driver in all situations. With the Audi AI:CON concept, Audi has already revealed a vision for a full level 5 autonomous driving car. This luxuriously appointed vehicle represents a future where occupants could be freed entirely from the task of driving, even on long journeys.
