...building their own cars. Lots of new players are entering the market, and it’s definitely not going anywhere. As that segment of the industry grows, there will be more opportunities for others to join in.”
Explaining why CVs and AVs matter to repairers, Farnsworth said, “Sensor-based blind zone and cross traffic alerts get knocked around in crashes, and ADAS are proliferating in lower-priced vehicles. All new light vehicles will have backup cameras, and the industry has agreed to make automatic braking and forward collision warning systems standard by 2022.
"Replacing a sensor torn off a car’s front end and swept up at a crash site can require a body shop diagnostic technician to go far beyond looking up a vehicle identification number to see what ADAS technology was original equipment.”
Repairing AVs also requires knowledge about repair and replacement of sensors, knowledge of electrical theory and information technology, and understanding of ADAS technology.
“ADAS assist drivers in driving and parking functions," Farnsworth said. "Through a safe human-machine interface, ADAS increase car and road safety, using automated technology, such as sensors and cameras, to detect nearby obstacles or driver errors, and respond accordingly. ADAS are developed to automate, adapt and enhance vehicle systems for safety and better driving. Although cars with ADAS are involved in fewer collisions, these systems are the costliest to repair.”
Discussing the number of sensors on a modern vehicle, which can exceed 100, Farnsworth pointed out even the headlights and tires contain sensors, and she predicted more sensors will be added to vehicles as they evolve. The addition of so many sensors necessitates scanning and calibration procedures.
“Sensors are the eyes and ears of ADAS, and when ADAS need to be serviced, it requires special equipment, operated by a specially trained technican,” she noted. “Many previously simple repairs now require ADAS calibration, which includes cameras, sensors and controllers, and requires specialized tooling and equipment.”
Farnsworth reminded, “ADAS systems use multiple sensors, and all need to be validated to solve the problem. In addition to the increased cost, the vehicle often requires...
