Abstract
As a field bus, CAN bus has been increasingly used in automotive electronic system.In this paper,a vehicle internal network architecture based on CAN bus system was introduced. Utilized the high-performance PIC18F258 MCU with CAN controller to design a CAN bus interface circuit, meanwhile shown the structure of major hardware and software design processes. The circuit has several advantages such as simple hardware design, high reliability,and powerful real-time.
