What Are ADAS Sensors?

Posted by Chief Technology on Jul 9, 2020 3:26:00 PM

Let's start at the beginning. ADAS stands for advanced driver assistance systems. Some people refer to them simply as driver assistance systems. These are the high-tech safety features that most drivers have come to expect in their new vehicles. Some examples include lane departure warning, emergency braking, blind spot monitoring, front collision warning, adaptive cruise control, self-parking and more.

Each of these systems relies on sensors in the vehicle in order to watch what’s going on around them. There are four common types of sensors: radar units, cameras, ultrasonic transmitters and steering angle sensors. Some driver assistance systems rely on multiple sensors, while others need just one to function properly.

Radar sensors are typically used in ADAS features that involve calculating distance. Most often you’ll find radar sensors mounted in or behind the front bumper or grille, in the side view mirrors and sometimes in the rear bumper. The radar sends out a high-frequency radio signal. If it reflects off an object and returns to the sensor, the sensor can use that information to calculate the distance between the vehicle and the object. This can help alert drivers to other cars, pedestrians or obstructions in the road.

For safety features that require more information than a simple radar signal can provide, you need a high-definition camera sensor with advanced data processing. Most of these camera sensors can be found inside a windshield, on the back of the vehicle or integrated with the rearview mirror. Other camera types provide a 360-degree view of a vehicle in its environment with multiple lower-resolution cameras placed around the vehicle, all designed to work together. Whatever kind of camera gets disrupted, they all need to be calibrated in order to function properly.

Ultrasonic transmitters.
If you thought self-parking systems would rely on cameras, think again. Parking assist features typically use ultrasonic sensors in the front and rear bumpers where they can reflect high frequency sound waves off of objects or people in close proximity to the vehicle. It’s pretty similar to radars. One difference is that most ultrasonic transmitters used in ADAS don’t need to be calibrated. However, if an aftermarket body part is used for a repair, it might interfere with the sensors and keep them from working properly. It’s always best to run a diagnostic scan to see if a sensor requires calibration.

Steering angle sensors.
For ADAS features involved with measuring the degree of steering wheel rotation, you need steering angle sensors. Those features include lane departure warning, adaptive headlights that follow steering, electronic stability control and adaptive suspensions. These kinds of sensors can be found in, you guessed it, the steering column.

The technology that goes into making modern vehicles safe is hyper complex. It’s also changing all the time. If you want to ensure you can properly repair vehicles outfitted with these kinds of sensors, you need an easy-to-use ADAS calibration tool and access to the latest OEM procedures. You can have both with Mosaic ADT from Chief.

What Do Automated Driver-Assistance Systems Do?

Posted by Chief Technology on Jun 11, 2020 3:23:00 PM

Mosaic ADT, the ADAS (advanced driver-assistance systems) calibration tool from Chief Collision Technology, is the only automated system on the market for repairing vehicle sensors and calibrating them according to OEM standards. But what does that really mean? Why does automation make a difference in ADAS calibrations?

In traditional structural collision repair, aesthetics and function were the signs of a good repair. In modern collision repair—where small sensors are built into windshields, mirrors, bumpers, you name it—accuracy is the most important thing. It can be frustrating trying to repair something you can’t really see or get your hands on. The key is having a tool you can trust. That’s where automation comes in. The automation features of Mosaic ADT allow for accuracy, significantly less room for error, less time to complete a calibration and a calibration that’s based on hard data, not just handiwork. Here’s how:

Automated alignment with the target.
One of the most time-consuming tasks in an ADAS calibration process is aligning the car accurately to the target. Systems that aren’t automated might have a tech lay a string on the ground, use plumb bobs from the center emblem on the hood, stretch out a tape measure or physically adjust the target stand to line everything up just right. Can you say “room for error”? With Mosaic, the tech parks the car within four or five feet of the target and attaches the wheel clamps so the machine can read the distance to the target. Everything else—distance, height, width and yaw—is all adjusted automatically.

Automated OEM procedures.
In order to choose the right target for calibration and complete an accurate repair, you have to use the correct OEM procedure and follow it precisely. Other systems will rely on techs to manually search for the correct standards, determine all the right steps and follow them. With Mosaic, all techs have to do is enter the VIN into the machine. Once the machine has identified the correct OEM procedure, a step-by-step process is automatically sent to the tablet. Just follow the directions on screen to reach an accurate repair. The software won’t let you skip a step, ensuring accuracy every time.

Automated documentation.
So you’ve followed the step-by-step process and completed your calibration. Next, Mosaic automatically generates documentation that captures all the data gathered throughout the process. It also makes a record in your system database that a calibration was completed successfully. Having proof that a calibration was performed to OEM standards gives you and your customer peace of mind.

Before you choose an ADAS calibration tool for your shop, consider how all the features work together. Will it help you work efficiently and accurately? We know Mosaic will.

ADAS Calibration and OEM Repair Procedures

Posted by Chief Technology on May 21, 2020 3:13:00 PM

OEM procedures and requirements are nothing new in collision repair. We’ve always needed precise specs to make a vehicle look and run like new. From emergency braking systems to lane departure warnings and more, modern vehicles are getting complex, so repairing them is more complex too.

Every time you complete a structural repair, you need to repair—aka recalibrate—the sensors in the advanced driver-assistance systems. In order to perform the most accurate calibration and keep drivers safe, you need three things:

1. The latest OEM repair procedures for the exact make and model you’re working on.
2. A clear, reliable process that can be followed again and again without mistake.
3. An ADAS calibration tool to calibrate the sensors.

Or, if you want all three things in one, choose the Mosaic ADT from Chief.

With Mosaic, you’ll always have access to the most up-to-date OEM standards for ADAS calibrations right there in the system database. Other aftermarket calibration systems hold shops responsible for updating OEM standards and repair procedures as they receive them from the OEM, or they use tools that have old data. Not with Mosaic. We get our data directly from the OEMs themselves and update it automatically for you.

Another common disadvantage of other calibration systems is not having a clear and repeatable process for techs to follow. Other systems simply give you the data and leave your techs to interpret it into a process of their own. Even for a skilled professional, that room for error isn’t very efficient or accurate.

Mosaic tells techs exactly what to do, step-by-step, through automation. Once the correct vehicle information has been identified in the database, the whole procedure automatically loads into the Mosaic tablet. The software automatically moves the targets and performs the scans and calibrations. All that your tech has to do is simply follow each step on the tablet to complete the repair--no searching or interpreting needed. The software also won’t let the tech skip any steps, so you can be sure the repair is completed accurately every time.

As more and more vehicles roll into your shop needing ADAS calibration, you’ll need an accurate, efficient and error-free system on your side. Consider Mosaic ADT to make pulling OEM procedures and following them a breeze.
