The National Institute for Automotive Service Excellence (ASE) recently hosted a webinar for service technicians, "ADAS Calibration---Do It Right and Document What You Do!"
The webinar was presented by Brent Johnson, Vehicle Service Group global product management for collision director, who stressed using proper procedures and materials to ensure accurate calibrations are performed for customers.
“All vehicles are calibrated in the factory using static calibration methods,” said Johnson. “But ADAS needs a real world reference. This means the system needs to know what to consider a threat and what it can ignore.”
He used an example of teaching someone how to drive. “They need to know if a vehicle coming across its path is a threat, or even a road sign because it has to protect you from certain dangers,” Johnson said.
He also noted artificial intelligence systems learn on its own, but it “takes a while to understand and learn.”
“If you’ve calibrated the system and return it to a customer, they are going to expect their vehicle to be what they’re use to,” said Johnson. “But it can take a while before the system to relearn the driver’s preferences after a collision, so you need to calibrate the vehicle so that it responds as the driver expects it to respond.”
