CAN Bus
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Controller Area Network (CAN) is a robust vehicle bus standard designed for communication among microcontrollers and devices without a host computer. It uses a differential signal on two wires to achieve high reliability in electrically noisy environments.
Example in context
“The electronic control units in this powertrain communicate via a high‑speed CAN bus to coordinate engine and transmission functions.”
“Bu güç aktarma organındaki elektronik kontrol üniteleri, motor ve şanzıman işlevlerini koordine etmek için yüksek hızlı bir CAN veri yolu üzerinden iletişim kurar.”
Where engineers use it
When integrating multiple microcontrollers in an automotive or industrial system, engineers select a CAN bus due to its fault tolerance and real-time capabilities. It is used for tasks like transmitting sensor data and actuator commands across a shared two-wire network.
Synonyms: Controller Area Network, CAN
Practice: can you use “CAN Bus” at work?
You are wiring an engine control unit and a transmission controller in a hybrid vehicle. Explain why a CAN bus is preferred over a simpler UART link for this application.
