Although some accidents are caused by technical failures, most accidents are caused by human error. It is this very human error that ADAS tries to fix. Systems like these include lots of active and passive safety features aimed at assisting the driver to eliminate their susceptibility to errors.
AI chip companies that specialize in ADAS have been constantly growing, with the current market value being estimated at around 25 billion USD as of 2021. That’s not the crescendo though with it being projected to grow up to 55 billion USD by 2030.
What is ADAS?
Let’s talk definition:
Advanced driver assistant systems can be described as passive and active electronic safety systems that are designed to remove the human error component in the operation of motor vehicles.
Typically, these systems use sensors in the vehicle to perceive the world around them and provide information to the driver or even better, take action automatically with the information perceived. Common sensors include cameras as well as radar.
In a nutshell, ADAS combines a variety of technologies to improve driver performance.
Remember how I mentioned the systems can be either active or passive? Allow me to indulge you in that regard.
Active and Passive ADAS Systems
These two systems are distinguished by the very sense of their names, active and passive.
Active Systems
In an active ADAS system, the ADAS processor does its thing and the vehicle takes direct action — ergo active system.
Some examples of active ADAS systems include emergency steering, automatic emergency braking, lane centering, and self-parking. See how in all these the vehicle is actively involved in what’s going on and not just an observer?
Passive Systems
Passive systems on the other hand are passive in the sense that all they do is process information and inform the driver of unsafe conditions.
It doesn’t matter how many sensors are installed, at the end of the day it’s the driver who has to take action to avoid the aforementioned unsafe conditions. This is where all warning signs come in with all those warning lights and flashing lights on the dashboard.
Some passive ADAS systems take it a step further with physical feedback like the steering wheel vibrating to warn the driver to steer away.
Every car enthusiast, or anyone who owns a four-wheeled machine for that matter, has heard of some technologies like anti-lock braking systems (ABS), traction control, and reverse cameras.
All these technologies fall under this passive ADAS systems umbrella.
How ADAS Systems Work
Essentially, ADAS systems are equipped with an array of advanced sensors and processors that far outweigh our five senses – or all the senses we use while driving for that matter.
All the blindpots when driving are covered by ADAS systems. All those deficiencies we have as human drivers like not seeing in the dark, not seeing some spots while reversing, not having our eyes watching all directions – not even superman can do all that, which is why ADAS systems are important.
The sensors survey the surroundings then the ADAS processors interpret the information and decide what needs to be done. From then on, the system will take action or inform you as the driver to enable you to make a decision depending on if it’s an active or passive ADAS system.
What the Future Holds for Advanced Driver Assistant Systems
These systems use technology and as technology grows, ADAS systems can only evolve to be better and more efficient. For instance, 5G is slowly gaining wind with the large bandwidth and low latency it offers.
Granted, ADAS doesn’t rely on 5G, but ADAS systems will still work better with the technology and open up the possibility of more applications. Typically, a lot of information is transmitted in an ADAS system so a slow system will only get slower.
In the future, it is possible for AI chip companies in this scope to incorporate some augmented reality to overlay important data like speed limit and navigation instruction.
