From Audi to Volvo, most "self-driving" cars use the same hardware

Much of the technology that underpins these systems is shared among the industry. A handful of companies like Bosch, Delphi, and Mobileye provide sensors, control units, and even algorithms to car makers, who then integrate and refine those systems. Depending on the make of car, these advanced driver assistant systems--ADAS in industry speak--might be called Traffic-Aware Cruise Control and Autosteer (Tesla), IntelliSafe Assist and Pilot Assist (Volvo), Distronic Plus with Steering Assist (Mercedes-Benz), Adaptive Cruise Control with Lane Assist and Traffic Jam Assist (Audi), and so on. But all of them work on the same basic principles. A fusion of sensors identify the lane markings on the road, the cars around you, and now even road signs like speed limits or school zones, and use this information to maintain your speed and a safe distance to those other cars.
