A Small CAN of History
CAN is short for Controller Area Network. It was originally created by the Robert Bosch company. CAN networks have found their home mostly in vehicles where they’ve been used since the late 1980s.
The first vehicles to use CAN were expensive luxury cars like Mercedes. As the average vehicle grew more complex and found itself stuffed with more and more electronics, CAN migrated to more ordinary vehicles.
CAN’s cousin, LIN (Local Interconnect Network) is newer and used for less critical subsystems where data transmission speed and reliability are less critical such as air-conditioning and infotainment.
CAN is designed for more critical systems like engine control, anti-lock brakes, parking assist etc.
