With every new model year more vehicles are equipped with Advanced Driver Assist Systems (ADAS). There is an added cost to owning these new technologically advanced vehicles. After a collision, certain systems require calibration as many sensors are in the bumpers, grill or attached to radiator support. Replacing components related to suspension or tires may also require alignment of ADAS. Similarly, replacing a windshield which has an ADAS camera mounted to the glass or the roof of vehicle, looking through the windscreen, will likely require camera calibration and the added expense associated with the service.
The most relevant ADAS to windshield replacement are:
- Forward collision warning
- Automatic emergency braking
- Adaptive cruise control
- Lane departure warning
- Lane keeping assist
The suite of sensors installed on a vehicle (camera, ultrasonic, radar and steering sensors) all work together for a complete assessment of vehicle location and direction of travel. ADAS sensors require calibration if their positions are changed.
Forward Facing Camera
Many new vehicles are equipped with forward-facing cameras. These cameras are used for target acquisition for adaptive cruise control, automatic emergency braking, lane departure warning and lane keep assist.
Static calibration is performed in shop using factory approved and designed targets or patterns to confirm and adjust where and what the camera sees and transmits back to the vehicle computer.
Dynamic calibration is the typical method for domestic cars and trucks. Dynamic calibrations are initiated with an OBD scan tool, or aftermarket scanner followed by driving the vehicle on relatively straight roads with clear lane markings at specified speeds and distances until the scan tool indicate calibration is completed successfully.
There are several vehicles which require Universal calibrations. This is typically completed by first aligning the camera in shop via static calibration and then proceeding to drive the vehicle to acquire a successful dynamic calibration.
Advanced Driver Assist Systems have undoubtedly made for a safer driving experience. Unfortunately, it has added a very large expense to a very common service. Autofocus Glass Inc has invested time and money to provide its customers with state-of-the-art tooling which allows calibrations on most vehicles that currently require ADAS calibration after windshield replacement. This allows us to offer a more convenient experience for customers as we are a one stop shop and no visit to the dealership is required after having your windscreen service completed.
