ADAS Calibration: What Are The Facts & Service Requirements?

Fri, 23 Aug 2024 14:19:00 GMT

What Is ADAS?

Many auto manufacturers started adding additional safety features, called Advanced Driver Assistance System, to high-end luxury vehicles in the 2000s. Today, most vehicles include one or more forms of ADAS technology across all makes and models. Motorists now expect top-notch safety features built into every automobile, not just the premium option. the technology has evolved to be more accurate, easier to use, and safer. Let’s review a few of the most common types:

ADAS Types

Modern vehicles utilize several types of Advanced Driver Assistance System technologies. Each type addresses and assists motorists with specific driving challenges:

Adaptive Cruise Control (ACC): More advanced than simple cruise control, ACC automatically adjusts your vehicle’s speed to keep a safe distance from the automobile in front of you. This feature provides a safer, more comfortable driving experience, especially on long drives like road trips.
Adaptive Headlights: Adaptive headlights automatically adapt to changing conditions like environmental lighting, road conditions, and vehicle position.
Automatic Emergency Braking (AEB): The ABE detects potential collisions and automatically employs the brakes if the motorist fails to respond quickly. This system helps reduce the severity and frequency of auto collisions.
Blind Spot Monitoring/Warning (BSM) or (BSW): Depending on your vehicle, this system can be a dashboard indicator light or side-view mirrors icon light. BSM and BSW systems help identify risks and warn the motorist via a visual or audible alert. Some warning systems may include a driver’s seat or steering wheel vibration.
Forward Collision Warning (FCW): The FCW alerts the motorist with a sound or vibration in the steering wheel to an impending collision with an obstacle in front of the vehicle. This system gives the driver additional time to react and helps avoid accidents.
Lane Departure Warning (LDW): This technology monitors lane markings on the roadway and alerts the driver when the vehicle drifts out of its lane without signaling. The LDW system helps motorists prevent accidental swerving and unintended lane changes.

How Does ADAS Work?

ADAS enhances a motorist’s capabilities and provides accurate data and feedback to improve decision-making while driving. It uses an elaborate network of sensors, cameras, and software to monitor the vehicle’s surroundings in real-time. It helps detect potential hazards and can take actions to avoid collisions to increase driver safety.

ADAS Cameras & Sensors

These cameras and sensors play a critical role in the functionality and accuracy of the Advanced Driver Assistance System. To operate correctly, they require precise, factory-specified calibration. Routine maintenance and calibration ensure the ADAS operates as intended, providing safety and convenience to the driver.

Steering Angle Sensors: Steering angle sensors detect the orientation of the steering wheel, influencing functionalities like adaptive headlights and blind spot detection. Vehicle structural changes or airbag deployment require an ADAS calibration service.
Front-Facing Camera: The front-facing cameras, mounted near the windshield, are vital for the automatic emergency braking and lane departure warning systems. A calibration is necessary after windshield replacement or front-end repairs.
Rear-Facing Camera: The location of the rear-facing cameras (sometimes called Back-Up Camera) varies based on your vehicle’s make and model. A calibration is necessary after rear window replacement or rear-end repairs.
Forward Radar Sensors: These sensors, located at the front of the vehicle, are crucial for adaptive cruise control and forward collision warning systems. They require calibration after any front bumper or collision repairs.
Rear Radar Sensors: Rear radar sensors help with blind spot warnings and rear cross-traffic alerts. They require calibration after any rear bumper removal and collision repairs.
Lidar Sensors: Lidar sensors (Light Detection and Ranging) provide a 3D representation of the vehicle’s surroundings, which is crucial for detecting objects and their distances. Schedule a calibration service when lidar units are disturbed, damaged, or replaced.
Ultrasonic Sensors: These sensors assist with parking and maneuvering in tight spaces by detecting nearby objects.
Wheel Speed Sensors: Part of your vehicle’s anti-lock braking system, these ADAS sensors monitor the speed of each wheel. They usually need calibration after brake or wheel hub work.
Yaw Rate Sensors: These sensors measure a vehicle’s rotation around its vertical axis, aiding ADAS’s stability control and cornering functions. They require calibration after significant suspension or chassis work.

ADAS Calibration Service Requirements

An ADAS calibration service is a highly technical process used to maintain the functionality and accuracy of your vehicle’s Advanced Driver Assistance System. It’s vital to orient the many sensors and cameras that process the data in the environment around your auto and provide the appropriate alerts. While some vehicles may notify drivers of ADAS issues via a dashboard warning light, not every automobile does this. Knowing when a minor fender bender, auto repair, or vehicle maintenance may impact the ADAS is important.

Auto Repairs & Part Replacements

Certain auto repairs and part replacements (i.e., brakes, suspension, windshields, bumpers) can knock vital advanced driver assistance system sensors out of alignment. An ADAS calibration service ensures that all the cameras, sensors, and other components adhere to the factory specifications. Only properly calibrated cameras and sensors can provide the reliable data necessary for the vehicle’s safety systems. Ask your service technician or read your owner’s manual to determine which auto repairs may require this calibration service.

Maintenance & Software Updates

ADAS calibration must adhere to strict industry standards. These standards ensure that each camera and sensor is precisely positioned and calibrated according to the factory specifications to provide accurate readings. The ADAS features must function correctly for driver safety. A minor misalignment or outdated software can significantly impact your vehicle’s ADAS effectiveness. Most of the time, ADAS software updates happen automatically via over-the-air (OTA) technologies. However, corrupted data or invasive malware in the ADAS software can require an automotive service center’s assistance.

Wheel Alignment: Performance Auto Tech in Corpus Christi, TX

At Performance Auto Tech, our guaranteed wheel alignment services put the latest diagnostic equipment in the hands of experienced technicians. That means we can perform repairs and scheduled maintenance according to strict manufacturer’s standards — maintaining your warranty and returning your vehicle to the road swiftly and safely.

What is a Wheel Alignment?

Over time, normal wear and tear on a vehicle’s suspension can cause a car, truck, or SUV to drive off-center. A wheel alignment is a periodic diagnostic and repair that measures the angle of your tires as they turn on the road and adjusts that angle according to manufacturer guidelines.

If you notice that your vehicle is driving off center, vibrations in the steering wheel, or that your fuel economy has worsened, these may be signs that you should ask a technician about your wheel alignment.

Here’s How it Works

To find the perfect alignment, our local technicians in Corpus Christi, TX, will measure three key angles in your vehicle’s wheels: camber, toe, and caster.

Camber. This is the inward or outward tilt of the wheels, which is visible from the front of a vehicle. Worn bearings, ball joints, and other parts of the suspension attached closely to the wheels can cause this misalignment. In severe cases, the vehicle may look like it’s shrugging or leaning.
Toe. Toe or toe-in alignment is the angle of your tires viewed from above. Most vehicles should have a slight inward toe, meaning the front of the tire points towards the middle of the car. Adjusting the toe-in angle often fixes an off-center steering wheel.
Caster. Your caster angle is about maintaining balance as you take tight turns and corners. This angle is difficult to recognize visually, but you can feel it as you drive. A positive caster can cause your car, truck, or SUV to pull to one side of the road. A negative caster causes overly light steering that needs constant adjustment to remain on-center.

How Often Should You Check Your Alignment?

Alignment recommendations will vary by manufacturer, but you should usually check your wheel alignment twice a year — once before and once after the winter season.

By regularly checking your vehicle’s alignment, you’re ensuring that your car is safe to drive. This will also reduce wear and tear on critical components like your vehicle’s suspension and tires.
