Advanced Driver Assistance Systems (ADAS) are designed to eliminate human error when operating vehicles of all types. ADAS uses advanced technologies to assist drivers, thereby improving their performance. But what exactly are these systems and why do we need them? While the answer to that question is complicated, it starts with the basics—ADAS help prevent accidents and save lives.
Why Do We Need ADAS?
While you may have heard of ADAS, you might not know why we need these assistance systems. There are several good reasons why ADAS should be incorporated into your new ride:
- They reduce accidents. Autonomous vehicles can eliminate many of the common causes of collisions—from distracted driving to drunk driving—which will help reduce accidents.
- They reduce traffic congestion. As autonomous vehicles become more common, they’ll start replacing cars that are driven by humans, especially in urban areas where traffic is most congested..
- They save you money. Without needing gas or insurance payments (and with fewer accidents), self-driving cars could save their owners money on transportation costs over time.
Introduction to ADAS
ADAS is a collection of technologies that help drivers avoid collisions and stay in their lanes. These systems are designed to be as unobtrusive as possible, so you can continue to drive safely while they take care of the hard work.
ADAS uses cameras, radar and sensors to identify objects around your vehicle and determine whether they pose a threat to your safety or not. If there are any threats detected by your vehicle’s ADAS system, it will alert you immediately so that you can adjust accordingly.
According to the National Highway Traffic Safety Administration (NHTSA), collision warning systems can reduce rear-end car accidents by 27%, lane departure warning systems reduce the number of accidents by 21%, and blind spot detection systems reduce lane collisions by 14%. These figures speak volumes about the value of the ADAS system.
NHTSA and Advanced Driver Assistance Systems
In 1999, Congress directed the National Highway Traffic Safety Administration to develop minimum performance standards for automotive occupant protection systems, which included ADAS. The NHTSA is a federal agency that is responsible for safety on public roads and helps ensure that drivers and passengers are safe when they get behind the wheel. Now, after more than two decades of work, we’re seeing some truly exciting developments from automakers.
In the 2000s, ADAS systems became popular in the US with a variety of safety features such as night vision, dynamic laser cruise control, lane departure warning, lane keeping assist, and so on. By 2018, the US Department of Transportation mandated that all new vehicles weighing less than 10,000 pounds (4,500 kg) be equipped with rear-view cameras. In addition, manufacturers have also researched and developed a variety of other technologies to improve vehicle safety.
The Future of ADAS
The future of ADAS technology is autonomous vehicles. As the technology advances and becomes more mainstream, we can expect to see a host of new challenges and regulatory issues arise.
The first challenge will be to ensure that autonomous vehicles are as safe or safer than human drivers. This requires solving a series of technological issues—for example, how to program an automated vehicle to respond appropriately when faced with potential hazards or unexpected situations. It also requires resolving many questions about who should be allowed access to these vehicles. For example, should they only be available for licensed drivers? And if so, are there any special requirements for licensing?
ADAS has a long history that dates back to the 1970s and 80s, with roots even earlier than that. ADAS is a combination of many different technologies, some of which were being developed independently of each other before they were used in conjunction with each other. The first ADAS systems used radar and camera technology to monitor speed and distance between vehicles. They did not have any control over steering or braking, but were able to alert drivers when they were getting too close to another vehicle ahead or in their blind spot.
VinFast’s Relentless Innovation in ADAS
After just three years in operation, VinFast has managed to bring to market a midsize SUV/C-segment with self-driving and steering assistance features such as lane departure warning, blind spot warning, and rear cross traffic alert. These cutting-edge technologies help reduce collisions common in urban traffic, particularly in densely populated cities.
- Traffic Jam Assist is an advanced driver assistance system that uses radars and cameras to compare the speed of surrounding vehicles with your own. It assists the driver in maintaining control of the vehicle during traffic jams or heavy traffic.
- Highway Assist helps maintain a safe distance from the vehicle in front of you, stay centered in your lane, and even help make sure that your speed is within legal limits by using GPS data.
- Lane Departure Warning helps you to avoid drifting or departing your lane by alerting you when one of the tires touches a lane marker.
- Lane Keeping Assistance is an automated system that helps the driver maintain their position in a lane by correcting any unintended deviations.
- Lane Centering Assist is an automatic steering system that keeps a vehicle in the center of its lane by relying on sensors and brakes to help counteract human driver error.
- Automated Lane Change Assist is a feature that warns drivers when they are trying to change lanes by sounding an alarm if another car approaches from the side. Lane Change Assist can help prevent accidents by warning drivers of vehicles approaching their blind spots.
- Adaptive Cruise Control is a computer-controlled system that automatically adjusts a vehicle’s speed to help it maintain safe following distances and stay within the speed limit.
- Traffic-sign recognition is a system that displays the information contained in traffic signs to the driver through an instrument cluster, infotainment screen, or head-up display. Most TSR systems can identify stop, speed limit and “do not enter” signs.
- Forward Collision Warning systems use sensors to detect obstacles in the vehicle’s path. They are especially useful for alerting drivers when traffic ahead has come to a standstill or slowed down considerably — but some may also note pedestrians, cyclists, and large animals that happen to be nearby.
- Rear-Cross Traffic Alert is designed to help you back out of spaces where other vehicles may be approaching from the sides.
- Intersection Assist utilizes the same camera and radar technology used by Pre-Collision Assist with Automatic Emergency Braking to detect oncoming traffic when making a left turn.
- Blind Spot Detection is a system designed to increase road safety by alerting the driver to vehicles that may have escaped visibility in side-view mirrors.
- Automatic Emergency Braking is a system that can identify when a possible collision is about to occur and respond by activating the brakes.
- Smart Parking Assist uses sensors, radars and cameras to take control of specific parking tasks or the entire exercise—helping drivers safely store their vehicle without damaging it or other cars parked nearby.
- Smart Summon Mode allows you to use your phone’s GPS as a target destination or manually select one and maneuver around obstacles until the vehicle arrives at its desired location.
- Automatic High Beam/Adaptive Driving Beam are lights that turn brighter and dimmer depending on the other vehicles and available light on the road.
- Driver-monitoring systems use cameras mounted on the dashboard to track driver drowsiness or distraction, issuing warnings when necessary to get their attention back onto the road.
So far, we’ve discussed the history of ADAS. We’ve seen how it evolved from simple safety features like antilock braking systems to more advanced driver assist technologies like automatic emergency braking. We’ve also covered some of the challenges that lie ahead in making these systems work effectively on real roads with real drivers behind the wheel.
While there’s still a lot of work to be done before new systems are ready for prime time, many people across industries are working hard toward this goal. It’s exciting to see where we’ll go next.
We hope you enjoyed learning about these important driver assistance technologies. They can help you drive safer and more efficiently, which is why many of them are prevalent in VinFast’s new SUV/C-segment. We think it’s important for drivers to understand what these systems do so they can make an informed decision on whether or not they want them installed in their EV!
