Guild 21’s Take on ADAS
Dec. 21, 2020—Guild 21 hosted a webinar this month that detailed the rising complexity of today’s vehicles with advanced driver assistance systems and the calibrations that need to be completed to ensure their proper repairs.
The webinar was hosted by David DeBoer, CEO of Burke Porter Group, who outlined the importance of ADAS calibrations, how to test their accuracy, and even offered an inside look at one of the industry’s most robust calibration tools.
“Now is the time to prepare collision bays,” said DeBoer of the rising popularity and complexity of ADAS systems.
Guarding Against False Positives
DeBoer warned of the pitfalls of ADAS calibrations, such as false positive testing results. He recommended performing a variety of tests with misplaced targets to determine if your system could provide incorrect results. The steps are as follows:
Intentionally misplace a static radar calibration target
Perform the calibration with proper OE scan tools, equipment, and procedures
If the system says it was accurately calibrated, then you know it was a false reading; but if the vehicle does not indicate a proper calibration, you know your system can be trusted
Repeat the test by moving the radar targets further from its correct position, and calibrate
Repeat the entirety of the test with various OEM vehicle types, makes, and models
Factory and Aftermarket Calibrations
DeBoer also discussed the differences between factory calibrations and aftermarket calibrations. Although they both aim to provide complete and proper repairs, the steps taken to get there vary exponentially based on the space, resources, and tools available.
Aftermarket calibrations usually consist of a human driving the vehicle into the calibration space and manually placing it along the checkered floor targets. Then, humans (the technicians) manually move each of the sensor’s targets into the specified location for the vehicle to recognize. DeBoer said the technicians placing the targets must be highly skilled and understand the patience necessary to complete these repairs. For aftermarket calibrations, DeBoer said the margin of error is much wider due to the amount of human interaction involved.
Factory calibrations are more commonly done using a standalone ADAS calibration system, said DeBoer. These systems operate using a conveyor belt to place the vehicle in the exact location, every time. Even the targets are moved via conveyor belts to ensure the proper positioning, removing human error.
The presentation concluded with DeBoer giving a demonstration of Chief’s Mosaic Advanced Diagnostic Technology, an automated ADAS calibration system. Chief, a collision technology company, partnered with Burke Porter Group to create a state-of-the-art calibration tool that minimizes the risk for human error.
Mosaic ADT automatically updates to provide technicians with the most relevant calibration information, directly from the OEMs. Mosaic ADT also documents what is done to the vehicle throughout the repair process, leaving a paper trail for shops and insurers to follow.
“It’s your craft and your customer’s life,” said DeBoer, “so do it right.”
