ADAS Calibration Facility Requirements

Nov. 19, 2020—During AAPEX’s virtual experience this week, Bosch emphasized the importance of ADAS calibration procedures after a vehicle has suffered a collision. 

ADAS features are made possible through the use of sensors, both camera and radar. The sensors are able to provide information to the vehicle such as its position within a lane or the distance between an object and the vehicle. 

When a vehicle is involved in a collision, the sensors could suffer damage that is undetectable to the naked eye. If not properly re-calibrated, the sensors could cause the vehicle to react to driving situations in potentially dangerous ways.

Calibrating these sensors is a meticulous process, but in order to start, shops need the proper setup to do so. During a Nov. 3 presentation, Bosch outlined its recommendations for an ADAS calibration facility. 

 

Floor Space

Bosch recommends a space of at least 10 meters wide by 15 meters in length to perform calibrations. This includes the size of the car as well as the length of floor targets needed to perform static calibrations of sensors. 

The floor should be level within 10 millimeters from one side of the workspace to the other. A slight incline along the floor of the space could result in the miscalibration of camera or radar sensors, thus skewing the vehicle’s reactions. 

 

Lighting

When it comes to the shop’s lighting, it is important to ensure there is evenly diffused light across the entire workspace. Minor details such as shadows, reflections, or even garage doors could hinder the accurate calibration of the sensors. 

Bosch recommends lighting that is adjustable according to seasons, weather, and time. All of which are moving variables depending on the location of the shop and the time of year. Bulbs with 300 to 400 Lumens are recommended by Bosch. 

 

Wall Coating

Bosch recommends a matte, solid-color wall coating in beige, grey, light grey, or white to perform calibrations. 

Similar to the lighting, reflections and shadows cast upon the walls of the shop could also alter the accuracy of a calibration. That is why the shop’s walls must be one solid color so the sensors are able to place the vehicle within the space. 

Wall coatings should also avoid any patterns that could mimic the calibration targets and confuse the sensors.
