We no longer depend solely on our eyesight to be safe on the road. Technology is “driving” us forward using Advanced Driver-Assistance Systems (ADAS), found in the majority of newer vehicles. Although it sounds like something out of a sci-fi novel, this technology is advancing rapidly to make semi-autonomous driving a reality.

What Is ADAS?

Advanced Driver-Assistance Systems consist of cameras, lasers, and radar to help with lane changes, collision avoidance systems, and navigation features. There can be multiple cameras in the windshield that work in conjunction with radar and lasers throughout the vehicle to improve overall safety while providing a comfortable driving experience. While this technology is not new, it is becoming increasingly popular in modern cars and is changing the industry. In 2020, more than 44% of new auto glass production includes ADAS features.

What are the features?

ADAS features included in most new vehicles are automotive navigation systems, blind-spot detection, lane-centring, lane-change assistance, and collision avoidance. A few standard features include automatic headlights, an anti-lock braking system, and adaptive cruise control.

How Does It Increase Safety?

ADAS increases vehicles’ overall safety on the road by “reacting” to potential accidents before they occur. In recent years, the percentage of car crashes and injuries have lowered thanks to ADAS technology. In 2019, the rate of forward-collision accidents dropped by 50% when auto brake technology was involved. Accidents caused by lane departure and changes have also decreased by 23% in the same year.

Why Does ADAS Require Recalibration?

Recalibration is necessary when the windshield is being replaced or when other adjustments are made to the vehicle, including bodywork and alignments. When replacing the windshield, the cameras need to go through a recalibration process to ensure they are working correctly. Why is this important? Suppose the cameras do not realign on the windshield according to the manufacturer’s requirements. They could misread the vehicle’s position on the road, putting the driver and the surrounding vehicles in danger.

Recalibrating ADAS

There are two processes for calibrating a vehicle after getting the windshield replaced. The first process is static calibration, which is done in the shop. Targets are set up with specific manufacturer measurements. The ADAS system is put into a learning mode and reads the marks. This allows the ADAS system to align the cameras to the precise placement they need to be pointing on the windshield. The second process is the dynamic calibration. The ADAS system is put into a learning mode while driving on the road with a scanning tool. Some vehicles require only one of the calibration processes, and others require both. After calibration is complete, a technician will test the operation of the lane departure system.

Recalibrating the ADAS system has been a challenge for many dealerships and windshield replacement facilities. Often, installers do not know they should be recalibrating the ADAS system upon replacement or do not have the necessary equipment to perform this task. ACR Auto Glass is one of the very few Winnipeg locations that can recalibrate the ADAS system to original working conditions.
