Submission + - Minor car crashes mean high tech repairs (cnn.com)
smooth wombat writes: With all the improvements in car safety over the decades, the recent addition of a plethora of high tech sensors and warnings comes with increased costs. And not just to have to have them on your car. Any time you get into an accident, even a minor one, it will most likely require a detailed examination of any sensors which may have been affected and their subsequent realignment, replacement, and calibration.
Some vehicles require “dynamic calibration,” which means, once the sensors and cameras are back in place, a driver needs to take the vehicle out on real roads for testing. With proper equipment attached the car can, essentially, recalibrate itself as it watches lane lines and other markers. It requires the car to be driven for a set distance at a certain speed but weather and traffic can create problems.
“If you’re in Chicago or L.A., good luck getting to that speed,” said Ebrahimi ”or if you’re in Seattle or Chicago or New York, with snow, good luck picking up all the road markings.”
More commonly, vehicles need “static calibration,” which can be done using machinery inside a closed workshop with a flat, level floor. Special targets are set up around the vehicle at set distances according to instructions from the vehicle manufacturer.
“The car [views] those targets at those specific distances to recalibrate the world into the car’s computer,” Ebrahimi said.
These kinds of repairs also demand buildings with open space that meet requirements including specific colors and lighting. And it requires special training for employees to perform these sorts of recalibrations, he said.
