Electrical Characteristics Design of Automobile Bus System

The CAN bus system consists of a CAN controller, a CAN transceiver, a data transmission line, etc., and has electrical characteristics such as differential signals, terminal resistance, and transmission rate. Differential signals are implemented through twisted pair cables, which can effectively reduce interference and noise and improve the reliability of data transmission. Terminal resistance is installed at both ends of the trunk to prevent signal reflection and interference. The transmission rate is selected according to specific needs, such as 1 Mbps, 500 kbps, etc.
