The Controller Area Network (CAN) is a robust vehicle bus standard designed to facilitate communication among various electronic components in automobiles. It allows microcontrollers and devices to communicate with each other without a host computer, making it essential for modern vehicles that rely on numerous electronic systems. Originally developed by Robert Bosch GmbH in the 1980s, the CAN protocol is widely used in automotive applications due to its reliability and efficiency. It supports real-time data transmission and can connect multiple devices, such as engine control units, brake systems, and infotainment systems, ensuring seamless operation and coordination among them.
