Over the last decade, multiple makes and models of American vehicles increasingly included ADAS (Advanced Driver Assistance Systems). This technology intends to help automate and enhance existing safety systems such as adaptive cruise control and automatic braking. While this technology has been on the market for a while, customers would be hard-pressed to find a new vehicle without some ADAS feature. If you need a windshield replacement and your vehicle has ADAS features, you need to have your windshield recalibrated after replacement to ensure that all of your safety features work correctly.
Certain ADAS features, such as tire pressure monitoring (TPS), have become nearly ordinary. However, other features, such as those listed below, have become increasingly prevalent in recent years:
These technologies use technology such as radar, cameras, sensors, networking, and computer imaging to help keep you and your family safe on the road.
Still unsure if your vehicle has ADAS or other forms of assistive technology? Here are some of the most common types of ADAS sensors and where to find them on your car:
If your vehicle has automatic braking, adaptive cruise control, lane departure warnings, or automatic headlight high-beam activation, the car likely has front-facing camera sensors. These are easy to see, as they’re usually mounted against the inside of the windshield. Camera sensors “translate” information it sees into metrics for your vehicle’s computer to interpret and use to control safety systems. If anything goes wrong with the cameras’ calibration, the sensors may not be able to accurately inform the car’s computer of any dangerous situations, rendering the safety features useless.
Front-facing radar sensors aid vehicles with features such as adaptive cruise control, forward collision warning, and automatic braking. The sensors transmit high-frequency radio signals that reflect off objects around the car and return to the sensor. These sensors are typically found in or just behind the front bumper or grille.
A vehicle’s ultrasonic sensors aid in parking assist and self-parking ADAS technologies. They’re typically found in the front or rear bumper covers, and they work similarly to radar sensors. Ultrasonic sensors do not require calibration, but they are meant to be in precise positions to work correctly.
Steering angle sensors provide your car’s computer information related to electronic stability control and adaptive suspensions. Additionally, steering angle sensors help with lane departure warnings and adaptive headlight technology. You won’t be able to see these sensors, though, as they’re usually built into the steering column.
Despite all of the new technology, not much can be done about rocks on the highway or other sources of trauma to your vehicle. If your vehicle has integrated ADAS features in its windshield, your windshield replacement isn’t as straightforward as it used to be.
While windshields, even on ADAS-integrated vehicles, look like they’re made from glass, they’re not just glass. While you can’t see them, your windshield has built-in sensors linked to the vehicle’s ADAS. If the sensors change position, even only by one degree or one millimeter, the entire system may be affected. If your car has an advanced feature, such as a lane departure warning system, the windshield has areas for the lens. These specialized areas must be lined up properly during calibration, or the ADAS feature won’t work correctly, putting you at risk on the road.
The process for ADAS calibration varies from vehicle to vehicle. Consider the fact that any single year, make, and model of a car has over twenty possible windshields. While calibration for some cars may be as simple as resetting the car’s computer, other calibration processes require the technician to set up lasers, take precise measurements, and make manual adjustments. ADAS calibrations require specialized tools and training, which our technicians at Collision Auto Glass & Calibration & Calibration have undergone successfully. We own our equipment, as well, so we can perform your windshield replacement accurately and promptly.
We do not recommend ignoring ADAS calibration after you have your windshield replaced. For the ADAS to work correctly, it requires inputs from a variety of sensors to interpret the environment and what’s going on in traffic around the vehicle. As mentioned before, ADAS sensors need precise aiming and calibration, and if any of them are misaligned, you could see any of the following problems in your car:
Problems with your vehicle’s steering can severely affect your safety on the road, along with the safety of everyone around you. You must get your windshield calibrated after replacement.
