Hardware Design of Automobile Bus System

The hardware design of CAN bus includes bus selection, bus interface circuit design and bus control circuit design. When designing the bus interface circuit, factors such as timing, electrical characteristics, and signal interference need to be considered. When designing the bus control circuit, factors such as bus protocol specifications, timing, and signal integrity need to be considered. In addition, attention should be paid to using high-quality components, reasonably laying out the PCB, using appropriate resistors and capacitors, adding filters and protection circuits, and using CAN bus transceivers.
