What does the ADAS acronym stand for (advanced driver-assistance systems)?

Advanced driver assistance systems calculate multiple information to help the driver

You have heard the word ADAS here and there without knowing its meaning? Are you intrigued by the latest technologies advertised by the car manufacturing industry?

After reading this article, you will have familiarized yourself with the ADAS system and learned how to maintain it to ensure its proper functioning for ever-safer driving.


What are the advanced driver assistance systems doing exactly?

As you might have guessed from the title, ADAS stands for Advanced Driver-Assistance System. These devices are meant to warn and protect drivers from potentially dangerous situations. Data collected by the sensors, radars, lidars and digital camera (positioned behind the rearview mirror) feed the system.


How do driver assistance systems help prevent accidents?

Driver assistance systems are not new. Since the 2000s, many safety measures made their way into the automotive market to help minimize road accidents. Did you know that in Canada, 94% of traffic accidents are attributed to driving errors? Without a shadow of a doubt, it can be said that mistakes happen everywhere: distractions while driving, speed and impaired driving are the among the main causes. Driving as safely as possible is everyone's business! ADAS can help reduce road accidents by up to 36% by addressing human failures. Thanks to the camera behind the rearview mirror, the vehicle can interact more safely with other road users by taking into account the speed, distance, direction and position of surrounding objects. The data transmitted by the digital camera is sent to the driver-assistance systems and used to send signals to the driver.

The popular belief was that ADAS were only found on higher end vehicle models, when in fact all lines of vehicles have them. In 2020, it is believed that 15% of vehicles in use in Canada will be equipped with ADAS technologies.

Here are the most popular smart devices. You probably have one in your vehicle!

The importance of the camera located on the windshield

Many of the previous features depend on one or more digital cameras located on the vehicle's windshield, behind the rearview mirror. Cameras can calculate the speed, distance, direction and position of surrounding objects. Thus, cameras transmit the information to the driver-assistance systems.


Did you know that advanced driver-assistance systems need to be maintained?

When a windshield is replaced, the camera must be recalibrated according to the manufacturer's standards. Each vehicle is subject to car manufacturers' specific standards. That is why the recalibration must be performed by expert technicians who have received recalibration training and use patented tools that meet the requirements of each manufacturer. To learn more about the recalibration process, you can visit our page on the subject.

Keep in mind that lack of or inadequate maintenance could cause malfunction of the advanced driver-assistance system. The good news is that most Canadian insurers now cover recalibration on a windshield replacement claim. If you wish to have your camera recalibrated, you can use our service center locator to find the nearest location.
