According to Elektronic Praxis, the autonomous electronic control units were introduced by the availability of low-cost and high-performance microelectronic components for different functional areas such as ignition, transmission control, or antilock braking systems.
In driving behavior, a significant improvement was a result due to the process synchronization that was distributed on various control devices that were necessary for controlled data exchange between the devices.
The digital communication system was introduced in the automotive industry, driven by several components which were growing for the body and electronics that is convenient enough to be needed in a connected/linked environment for application such as climate control, seat and mirror adjustment, electric windows, anti-theft systems, central light and locking mechanisms, etc.
The length of the wiring or mitigated neuralgic cabling points are reduced in an automotive area where the digital communication system, a primary medium. For example, grommet from the car’s inside to the front doors. Due to the security of data transmission with high demand in an environment that is full of electromagnetic interference, developing a suitable communication concept is necessary.
The situation described above led to the initial point to develop CAN i.e. Controller Area Network protocol which was started in 1983 by Bosch.
