In this case, we discuss about the SAE International classification for autonomous vehicles. We also have 5 levels from no technology integrated to the car at level 0.
Level 0: No automation
Does what it says on the tin. The car is not automated in any way and relies on a human for all of the tasks. It’s also know that all things such as: Execution of Steering and Acceleration/ Deceleration – Monitoring of Driving Environment – Fallback
Performance of Dynamic Driving Task are depends on the processing of human.
Level 1: Driver assistance
Level 1 involves the human and a computer system working together on tasks, with the majority of the work being done by the person at the wheel. It encompasses many cars that are already on the road today running with so-called assistance modes such as Jaguar Land Rover’s experimental off-road vehicles, capable of using off-road cruise control.
SAE International explains level 1 driver assistance systems include steering, acceleration/deceleration as well as features that use “information about the driving environment”. Ultimately, though, the human is expected to do the majority of the work.
Level 2: Partial automation
Here’s where things start to get serious. In level 2 systems, the steering and speed of the vehicle are controlled by “one or more driver assistance systems” but a human controls the other elements of driving.
Tesla’s Autopilot system has been described as being within the level 2 bracket, although it is also considered, by some, to be a level 3 vehicle. It’s testing in some development countries, especially in Dubai.
Level 3: Partial automation
Vehicles in level 3 and above are considered “automated driving systems”. The substantial difference here is that the vehicles are able to monitor the driving environment around them. Crucially, these types of vehicles make decisions themselves. For instance, a level 3 car will be capable of seeing a slower moving vehicle in front of it before taking the decision to overtake. The human is on hand, mostly, to intervene if things go wrong.
Level 4: High automation
The autonomous cars Ford wants to put on the road by 2021 are considered to be level 4 vehicles.
SAE describes this as having “driving mode-specific performance by an automated driving system of all aspects of the dynamic driving task, even if a human driver does not respond appropriately to a request to intervene”. Put more simply, if something goes wrong, the car can handle it itself.
Level 5: Full automation
In this scenario, no human control of a vehicle is needed at all. Level five has full automation and vehicles don’t need any pedals, steering wheels, or controls for a human to take charge. Google, through its Waymo subsidiary, is working on producing this level of automation.
We are known that the function of autonomous car, so everything has both sides. In this stage, we will discuss on the affected side of this smart car:
Advantage:
-> Easy to use
-> Make human feel comfortable
-> We can do other things when we are driving in smart car
-> Easier to control and changing equipment
-> Some smart car have eco-friendly
Disadvantage:
-> The car can be hacked and can cause accident
-> Sometimes, it can create error and maybe cause dangerous for people
-> It’s must be repair and test follow on periodic
These are something that we should know the level of autonomous car. Although it still have some errors, it can replace self-driving and make the customer feel comfortable. In the future, the autonomous car will popular, we also interact with car to know that how long we go to somewhere, reduce traffic jam by using smart system or reduce traffic accidents.
