The Impact of Alignment on Advanced Driver Assistance Systems (ADAS)

Your ADAS Systems Need Proper Alignment

Modern cars have advanced driver assistance systems. Lane keeping assist. Adaptive cruise control. Automatic emergency braking. Blind spot monitoring. These systems use cameras, radar, and sensors. They depend on precise vehicle geometry. If your alignment is off, these systems can malfunction. They might disable themselves. They might give false warnings. They might fail when you need them. Alignment isn't just about tire wear anymore. It's about safety system functionality.

ADAS Systems Affected by Misalignment

• Lane keeping assist - relies on camera detecting lane markings
• Adaptive cruise control - needs accurate vehicle positioning
• Automatic emergency braking - requires precise forward detection
• Blind spot monitoring - depends on accurate sensor positioning
• Forward collision warning - needs accurate distance measurement
• Parking assist - relies on camera and sensor calibration
• Stability control - uses suspension geometry for calculations
• All systems rely on proper vehicle alignment for accuracy

How Alignment Affects Sensor Calibration

ADAS cameras and sensors are calibrated for specific vehicle geometry. When you get alignment, technicians must recalibrate these systems. The car's computer needs to know wheel angles, height, and positioning. Misalignment throws these measurements off. Systems can't recalibrate. They might disable themselves or malfunction. After any alignment service, ADAS systems should be recalibrated.

Why ADAS Recalibration Matters

• Alignment changes vehicle geometry
• Geometry changes invalidate previous ADAS calibration
• Systems must recalibrate to new geometry
• Without recalibration, systems may malfunction
• Recalibration ensures safety systems work properly
• Modern vehicles have multiple ADAS systems to recalibrate
• Recalibration takes 30 minutes to several hours
• Cost varies from free to $150+ depending on shop

The Safety Implications

Your ADAS systems are safety features. They prevent accidents. They protect you and your passengers. If they malfunction due to misalignment or failed recalibration, you've lost critical protection. You might not even know they're not working. The automatic emergency braking might not activate. The lane keeping assist might not prevent a drift. This is why alignment and ADAS recalibration are critical safety services.
