Analysis and Testing of Improving Transmission Distance of CAN Bus

The CAN Bus is a serial communication system which supports distributed control and real time control. It is spread out in industry field because its 1 Mbps transmission speed and over 10 km distance. But in real system, it’s performance isn’t ideal. Aiming at this problem and combining an actual system, various factors affecting transmission capability were analyzed. The methods improved actual communication distance of CAN Bus was put forward.
