Waymo, an Alphabet company, has launched the world's first driverless taxi service. Residents of Phoenix, Arizona will be able to use the Waymo One app to book their ride and be picked up by a self-driving car in a 50-square-mile area. An important milestone after a year of testing with a few hundred customers and 11 years after the start of road trials . Car autonomy levels But what is a self-driving car? To be precise, even if the use of this term has become widespread in practice, we should more correctly speak of self-driving cars, so as not to interfere with the concept of autonomy which would imply some form of conscience. But beyond the terminological disputes, to understand something you can use the taxonomy developed by the SAE (The Society of Automotive Engineers) which defines 6 levels of automation. In the first three levels the driver always has complete control, even if some automatic systems are activated.
In the subsequent levels the driver does not drive, but limits himself to a support or India Mobile Number Data substitute activity. Level 0: no automation. The car controls are completely manual, but the system can signal some events to the driver (blind spots, out of lane, emergency braking) Level 1: the car has some automation system, for example one that controls and stabilizes the speed set by humans (cruise control) or maintains the lane Level 2: the vehicle has multiple automation systems, for example it can steer and accelerate automatically, but the driver controls the activities and can take control at any time Level 3: The car can perform most driving functions, but under certain conditions. For example, in the case of congested traffic, it hands over the controls to the driver Level 4: the car drives itself, but in limited areas and under certain conditions. The human option is always active Level 5: the vehicle is fully automated under all circumstances.
No need for human attention. How do driverless cars work? Driverless vehicles are among the most complex "smart objects" because they must learn to "see" the surrounding environment and make appropriate decisions on the move. For this they require different hardware technologies that acquire useful data and software based on artificial intelligence algorithms capable of combining them and making sense of them. Radars (Radio Detection and Ranging) are used to estimate the distance and speed of objects, using electromagnetic waves. They may have trouble identifying objects that are not metallic or have particular shapes. They scan the environment in front up to about 200 meters away. They are usually installed at the front and rear of the car.
