Understanding ADAS Calibration
Modern vehicles are equipped with Advanced Driver Assistance Systems (ADAS) that enhance safety on the road. These systems use sensors to constantly monitor the area around the vehicle, helping to provide warnings or even taking temporary control of braking and steering. However, for ADAS to work correctly, these sensors need to be properly calibrated. This makes calibration services an essential part of vehicle maintenance.
What is ADAS Calibration?
To understand ADAS calibration, let’s first clarify what ADAS is. Advanced Driver Assistance Systems include various safety features that help protect drivers and passengers. If a vehicle has been in an accident or has had repairs, the ADAS must be recalibrated to ensure it works as intended. This process ensures that all systems are functioning properly and that the vehicle remains safe to drive.
ADAS calibration involves aligning and testing the sensors that support safety features like forward collision warning (FCW), lane departure warning (LDW), and automatic emergency braking (AEB). Proper calibration helps sensors know where to look and what to monitor. Even a tiny misalignment can affect how these sensors perform. For example, AAA notes that a sensor out of alignment by just a fraction of an inch can lead to significant errors in its readings, affecting safety.
Why Sensor Misalignment Matters
When a vehicle is new, ADAS sensors are set to precise factory positions. Over time, things like minor accidents or repairs can cause these sensors to shift. For example, if a vehicle has a forward ADAS camera on the windshield and the glass is replaced, the camera will need recalibration to work correctly.
Not all ADAS sensors can alert you when they need recalibration, so it’s important for auto professionals to follow OEM (Original Equipment Manufacturer) guidelines to ensure everything works as it should.
Types of ADAS Calibration
Vehicles with ADAS may need either static calibration, dynamic calibration, or both, depending on their specific needs. Each type of calibration uses different tools and conditions to ensure everything is aligned properly.
In summary, knowing about ADAS calibration is important for keeping your vehicle safe and running well. Regular checks and recalibrations by trained professionals can help ensure that your vehicle’s safety systems work effectively, giving you confidence on the road.
