Level 3 Autonomous Vehicles Explained: Features and Current Availability

The level 3 autonomous driving level marks a major jump in car technology, allowing the vehicle to manage most driving tasks under certain conditions while demanding that a driver take over when invited. Unlike level 2 systems, which require constant attention, level 3 allows moments of real driving in the hands.

This breakthrough is already making its way in production cars, with some car manufacturers leading the charge. By mixing advanced sensors, AI and regulatory approvals, level 3 shapes the future of mobility.

Here is what level 3 autonomy really means, how it differs from previous levels and which brands are already deploying it today.

There are a number of different levels of autonomous driving

In the modern world, we are all used to having a certain driver level in our cars, whether more advanced autonomous characteristics or simple parking sensors. To understand what level 3 autonomy is and why it is so important, we must examine the levels of autonomy and what they mean each.

The six levels of driving autonomy

• Level 0 – No driving help

• Level 1 – Driving assistance

• Level 2 – Partial driving automation

• Level 3 – Conditional driving automation

• Level 4 – High driving automation

• Level 5 – Complete driving automation

It is difficult to believe that it was not so long ago that most traditional cars were sitting in level 0. In the modern era, it is almost impossible to buy a car that does not come at least with assists. Things like the cruise control will put your car at this level. However, many cars have started a traditional deployment of level 2 functions, where the vehicle can control management and acceleration / deceleration.

Level 3 may seem a subtle leap in the average person, but the technology it executes is much more advanced than what you would find in a level 2 vehicle. Level 4 goes further, allowing automation in most cases, with a very minimal human interaction. Vehicles at level 5 do not require any entry or attention of a human. Although the concepts of these levels exist, they are still far away.

The key characteristics of level 3

As mentioned above, level 3 autonomy is called conditional driving automation. This essentially means that the vehicle can manage most driving processes alone in specific conditions, but the driver must be aware and ready to take over from the car when systems encourage them to do so.

Essentially, cars that qualify for level 3 can speed up, decelerate, brake, direct and navigate outside the stimuli, including obstructions or other vehicles. Generally, cars that offer this level of autonomy can only work in specific geographic areas under certain conditions. As a driver of a level 3 vehicle, you must maintain your concentration and be easily available to take over from the car.

The way in which level 3 autonomy is different from level 2 autonomy

Level 2 is defined as partial driving automation. By comparing this to the automation of conditional driving (level 3), it can be difficult to understand the differences. From a technological point of view, level 3 is a huge leap forward, with a number of impressive systems under development to execute the show.

The equipment behind the level 3 autonomy

• Cameras

• Sensors

• Radar

• Lidar

In this sense, there is no massive difference between vehicles capable of level 2 autonomy and those capable of level 3. The two levels of autonomy require a certain number of different sensors which can absorb external information. What this means is that there is often a certain level of scalability, certain cars being now capable of level 3 autonomy in the future, despite the achievement only of level 2.

However, there are three basic differences. The first being the addition of Lidar to level 3 cars. This allows a 3D cartography, which allows better decision -making. Level 3 vehicles also have many more redundancy systems, where level 2 vehicles mainly depend on the driver as a backup for any failure. The third thing is the computing power, with level 3 vehicles requiring high -performance computer fleas.

The software behind level 3 autonomy

The difference between level 2 and level 3 is much greater when you take a look at the software behind the cars and how they work. Both take information in the outside world, but level 2 vehicles use you as the main decision -maker, while level 3 vehicles are able to make their own decisions, to be able to react to the traffic flow or exceed cars that move too slowly.

The way vehicles on both different levels of information processing are very different. Level 2 cars adopt a simple approach to the merger of sensors, adopt an approach based on the rules on the functioning of systems in particular circumstances. Level 3 cars push things further, incorporating a higher level of AI in the operation. This allows a higher level of interpretation with regard to the mixture of information sent by sensors and cameras. These systems can generate a 3D provision of the environment around the car and use it to determine the best action plan.

Level 3 autonomy is on the horizon, with a number of car manufacturers pushing research

For the most part, cars on the road which offer a certain level of automation are considered to be level 2. This includes a number which claims to offer really free driving. However, some car manufacturers from around the world have started to prowl vehicles capable of level 3 autonomy, with a number of close competitors behind them.

Which now offers level 3 autonomy

Currently, there is only one car manufacturer selling vehicles equipped with level 3 autonomy in the United States and it is Mercedes-Benz. He comes to their flagship S class of class S as well as his electric counterpart, the EQS. It is only regulated for use on highways specifically described in California and Nevada.

BMW and Honda are the two car manufacturers closest to Mercedes-Benz’s achievements, both benefiting from publicly sold vehicles with a level 3 capacity. Although they were only sold in their local markets, this shows that the two car manufacturers have ready-to-leave systems.

There are a number of other car manufacturers who are very close to level 3 autonomy in their cars, with a large barrier at the entrance being the legal obstacles they must overcome. Things like Tesla’s automatic driver, Ford Bluecruise and GM supercruise are only considered to offer level 2 autonomy.

Waymo offers an autonomous e-hailing

One of the largest developments in the world of autonomous cars is Google Waymo. It is a carpooling service offered in certain areas where the car you order is completely independent. These vehicles are considered to have reached level 4 autonomy, with the capacity to manage all driving inputs but to be limited to certain areas and environments. However, they still have a long way to go before they are perfect.

Waymo opens a brand new debate on the property of cars. Although autonomous taxis will not satisfy those who lead for pleasure, they will make it more difficult to justify the purchase of a basic suburban car. When they are more easily available, you can go wherever you want without having to interact with a driver, preserving your peace and personal space, while saving you the many costs of possession of the vehicle.
