Description:
Abstract With the growing number of onboard ECUs, the load of classical CAN (Controller Area Network) is aggravated to produce transmission delay issue. A new protocol CAN-FD (Controller Area Network with Flexible Data-Rate) was presented by the BOSCH company to meet the high speed and real-time data exchange needs of the intelligent vehicles and ITS (Intelligent Transport System). For the vehicle electronics, the CAN-FD data network is still growing up. In this paper, the classical CAN and CAN-FD in protocol are compared through experiments. Results show that: (1) the terminal resistors have more effects on the CAN-FD than the CAN; (2) the bit rate of the CAN-FD can be ten times of that of the CAN; and (3) the data transmission efficiency of the CAN-FD network is affected by both the bit rate and the data length. Additionally, the physical network configuration takes decisive effect on the minimum frame interval of the CAN-FD frame.
