The CAN Bus, or Controller Area Network Bus, 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. Developed in the 1980s by Bosch, the CAN Bus is widely used in automotive applications due to its reliability and efficiency. It supports real-time data transmission, enabling systems like anti-lock braking systems and engine control units to share information quickly, enhancing vehicle performance and safety.
