Advanced driver-assistance systems (ADAS)
technology is now standard on most new vehicles. Many drivers have got used to
features such as lane-keeping assist (LKA), automatic emergency braking (AEB),
and adaptive cruise control (ACC).
However, as common as ADAS are, the
collision repair industry hasn't fully caught up. And that’s a problem, because
ADAS changes a lot about auto repair. Not all shops are equipped to
handle ADAS, and the consequences of getting it wrong are serious.
What are ADAS?
Advanced Driver Assistance Systems are
electronic features that help drivers steer, stop, and brake their vehicles.
ADAS use sensors, cameras, radar, LiDAR, and onboard software to interpret
surroundings and provide warnings and interventions.
Examples of ADAS
Popular ADAS features include:
●
ACC:
Automatically changes your vehicle's speed to maintain a safe distance from the
vehicle in front of you.
●
AEB:
Detects an imminent collision with a vehicle, cyclist, pedestrian, or obstacle
and automatically applies the brakes if you can’t react in time.
●
Blind spot monitoring: Alerts you if there’s a vehicle in your blind spot when changing
lanes.
●
LKA and LDW (lane departure
warning): Sends an alert if you unintentionally drift
out of your lane and can gently steer the vehicle back into place.
●
Traffic sign recognition: Uses cameras to read speed limits and other road signs and displays
them on your dashboard.
ADAS, collision repair, and
calibration
ADAS features depend on millimetre-level
precision to function correctly. This means even a minor collision can knock
them out of alignment. What’s even more concerning is that these misalignments
are often invisible, at least to the naked (and untrained) eye. So while most
drivers might think about the visible damage after a collision, they should
also ponder if there’s damage they can’t see.
What happened to the sensors behind the
bumper? How’s the camera mounted behind the rearview mirror? Is the radar unit
tucked inside the grille OK? These are the questions collision repair
technicians must ask. Because while these components may look untouched, and
may even test as functional, their alignment, the precise angle at which they
read the road, could be off. And this can be dangerous.
It’s why calibration is essential. After any
auto repair that affects an ADAS component, or even the area around it, the
system in question requires recalibration back to manufacturer specifications.
That process comes in two forms: static calibration and dynamic calibration.
●
Static calibration: Collision repair techs do this in a controlled indoor environment,
using target boards, precise measurements, and diagnostic equipment to reset
the system while the vehicle is stationary.
●
Dynamic calibration: This requires driving the vehicle under specific conditions,
including particular speeds, road types, and distances, so the system can
recalibrate itself in real time.
Many vehicles require both types of
calibration after an auto repair. The threshold for triggering a required
recalibration is lower than most drivers expect. For example, a windshield
replacement almost always requires recalibration because the forward-facing
camera mounts to the glass. The same is true for a wheel alignment, bumper
repair, or any work near a radar or sensor housing. In short, recalibration
isn’t just needed after serious collisions. It’s required after a wide range of
auto repairs.
What auto shops need to properly
service ADAS
ADAS features are common on far more than just
luxury vehicles today. Over
90% of new vehicles sold now come standard
with at least one ADAS feature. Therefore, it only stands to reason that most
collision repair shops today perform ADAS calibration as part of a standard
auto repair.
The problem is that precise calibration isn't
easy, nor is it cheap. It requires professional diagnostic scan tools,
calibration target systems, and a dedicated workspace with a flat, level floor
and enough space to position targets at the exact distances the system
requires. It also requires collision repair technicians who are trained not
just in general auto repair, but specifically in ADAS diagnostics and
calibration procedures, ideally with the right certifications to back it up.
How many shops can do this?
Many independent collision repair shops don't
have all these things. Some have the tools but not the trained staff. Some have
staff with general knowledge but lack manufacturer-specific equipment. Others
quietly outsource calibration to a dealership or third party, which may be
fine, but only if it's disclosed, documented, and included as a verified step
in the repair process.
The collision repair businesses that are the
most concerning are the ones that skip the step entirely, or which perform a
calibration check without the proper setup, producing a result that looks
complete on paper but leaves the system misaligned on the road.
For drivers, the unsettling part is that a
mis-calibrated ADAS feature often gives no obvious warning. The vehicle may
drive normally; no dashboard light appears, no warning signal beeps. So, the
lane-keeping feature still seems to work––until the moment you need it the
most. During a sudden stop, an unexpected lane drift, or a vehicle appearing in
a blind spot, that mis-calibration reveals itself. And frighteningly, by then
it may be too late.
Making sure your ADAS are
calibrated
It’s important for drivers to understand this
isn't about mistrust; it's about asking questions the auto repair industry has
been slow to answer.
Drivers should ask the technician they’re
speaking to questions like:
●
Do you have in-house ADAS
calibration capabilities?
●
Do your technicians have
ADAS-related certifications?
●
Will you provide a calibration
report with my repair?
Ultimately, ADAS have made vehicles safer. But
these systems can only do this if
professional
collision repair technicians do their jobs correctly. This is a special report for our Formula 1 readers.
